Version 4.1.1 (30 Nov 2022)
===========================
2022-11-29: bero
Fix mismatch between #pragma GCC diagnostic push and pop statements
2022-11-26: wsfulton
#2449 Fix undefined behaviour in ccache-swig calculating md4 hashes and possibly
also handling errors when CCACHE_CPP2 is set.
2022-11-25: wsfulton
#961 Fix syntax error parsing unnamed template parameters with a default value.
2022-11-25: olly
#2447 Fix undefined behaviour in swig's parser when handling
default parameter expressions containing method calls.
2022-11-13: olly
[PHP] #2419 Update the documentation to reflect that SWIG 4.1.0
dropped support for -noproxy when generating PHP wrappers.
2022-11-05: wsfulton
#2417 Fix -swiglib for Windows when building with CMake.
2022-11-02: wsfulton
#2418 Fix infinite loop handling non-type template parameters.
Fixes infinite loop due to () brackets in a non-type template
parameter containing an expression.
2022-10-28: wsfulton
[R] R rtypecheck typemaps
Further switch to use rtypecheck typemaps instead of hard coded logic.
The full switch to typemaps is deferred until swig-4.2 as it can't be fully
backwards compatible. For now a warning is provided to help the
transition. It provides the full typemap that should be placed into
a user's interface file, for example:
%typemap("rtype") int32_t * "integer"
void testmethod(int32_t * i);
void testmethod();
If there is no rtypecheck typemap for int32_t *, the warning shown is:
example.i:7: Warning 750: Optional rtypecheck code is deprecated. Add the
following typemap to fix as the next version of SWIG will not work without it:
%typemap("rtypecheck") int32_t * %{ (is.integer($arg) || is.numeric($arg)) %}
The warning is shown for any code that previously used "numeric", "integer" or
"character" for the rtype typemap. Copying the rtypecheck typemap as
shown into the user interface file will provide the appropriate fix and
the warning will disappear. This is important to do as swig-4.2 will
not be able to provide this helpful warning.
2022-10-27: wsfulton
[R] Allow NULL to be used in overloaded functions taking shared_ptr.
Also fixes special variable $argtype expansion in rtypecheck typemaps.
2022-10-26: wsfulton
[R] Improve R wrapper error message when calling overloaded methods
when incorrect types passed are passed to the overloaded methods.
Old unhelpful error message:
Error in f(...) : could not find function "f"
Example of new improved error message:
Error in use_count(k) :
cannot find overloaded function for use_count with argtypes (NULL)
2022-10-26: wsfulton
[R] #2386 Fix memory leak in R shared_ptr wrappers.
Fix leak when a cast up a class inheritance chain is required.
Version 4.1.0 (24 Oct 2022)
===========================
2022-10-24: wsfulton, AndLLA
[R] #2386 Fix problems in shared_ptr wrappers where the class names
were not consistent when using the shared_ptr template or the actual
underlying type.
2022-10-24: wsfulton
[R] Add support for special variable replacement in the $typemap()
special variable macro for R specific typemaps (rtype, rtypecheck,
scoercein, scoereout).
2022-10-24: wsfulton
[R] Polymorphism in the wrappers was only working for C++ classes,
now this works for C++ structs too.
2022-10-19: olly
[Lua] #2126 Fix type resolution between multiple SWIG-wrapped
modules.
2022-10-17: wsfulton
[R] #2385 Add support for std::vector<std::vector<std::string>>.
2022-10-14: murillo128
[Javascript] #2109 Tweak unsigned long and unsigned long long typemaps
to create a v8::Number instead of v8::Integer if the value exceeds
the size of v8::Integer. Note that the v8::Number value will be
imprecise if the value is > MAX_SAFE_INTEGER.
2022-10-14: olly
[R] Arrange that destructors of local C++ objects in the wrapper
function get run on SWIG_fail (which calls Rf_error() which calls
longjmp()).
2022-10-14: olly
[Lua] Arrange that destructors of local C++ objects in the wrapper
function get run on SWIG_fail (which calls lua_error() which calls
longjmp()).
2022-10-13: wsfulton
[R] Add missing SWIGTYPE *const& typemaps for supporting pointers
by const reference.
2022-10-10: wsfulton
#2160 Fix compile error when using templates with more than one template
parameter and used as an input parameter in a virtual method in a
director class (problem affecting most of the scripting languages).
2022-10-10: treitmayr, wsfulton
[Python, Ruby] #1811 #1823 Fix invalid code generated in some cases when
returning a pointer or reference to a director-enabled class instance.
This previously only worked in very simple cases, now return types are
resolved to fix. A bug in template instantiations using pointers also
works now.
2022-10-06: wsfulton
[CFFI] #1966 #2200 Remove code for Common Lisp CFFI. We dropped support
for it in SWIG 4.0.0 by disabling it as the first stage. This is the
final stage for complete removal as there has been no meaningful
progress to revive it to the status of experimental language.
2022-10-06: olly
[Python] #2390 Remove deprecated and apparently useless defarg.swg
The only documentation is in the file itself and describes a Python
wrapper around the C function defined here, but digging though the
git history this Python wrapper doesn't seem to have ever actually
been generated by SWIG.
This file was also marked as deprecated in 2005.
2022-10-06: wsfulton
[Java] #2048 Fix quoting for doxygen \image command to quote the output
file name generated into the html src attribute.
2022-10-05: benjamin-sch
[Python] added an interpreter counter to fix deinitialization
issues if multiple subinterpreters are used
2022-10-05: olly, wsfulton
#672 Add support for parsing C++11 final classes such as:
class X final {};
This no longer gives a syntax error.
2022-10-05: wsfulton
[OCaml] Fix %rename for enum items. Previously the rename had no effect.
2022-10-05: olly
#1465 Report errors in preprocessor expressions by default
Until now SWIG quietly ignored such errors unless -Wextra (or -Wall
which implies -Wextra) was passed, but this is unhelpful as it tends
to hide genuine problems. To illustrate this point, enabling this
warning by default revealed a typo in the preproc_defined.i
testcase in SWIG's own testsuite.
If you really don't want to see this warning, you can suppress it
with command line option -w202 or by using this in your interface
file:
%warnfilter(SWIGWARN_PP_EVALUATION);
Both will work with older versions of SWIG too.
2022-10-04: olly
#1050 Consistently define SWIG_VERSION both at SWIG-time and in
the generated wrapper. Best practice remains to check at SWIG-time
where possible because that results in smaller generated wrapper
sources.
SWIGGO and SWIGJAVASCRIPT are now defined in the generated wrappers
to match behaviour for all other target languages.
The undocumented SWIGVERSION macro is no longer defined.
2022-09-29: olly
#2303 SWIG's internal hash tables now use a better hash function.
The old hash function only considerd the last five characters
plus the least significant bit of the last-but-sixth character,
which as you might guess generated a lot of many-way collisions.
This change seems to give about a 4% reduction in wallclock time
for processing li_std_list_wrap.i from the testsuite for Python.
The hash collision rate for this example drops from 39% to 0!
2022-09-29: wsfulton
#2303 Type tables are now output in a fixed order whereas previously
the order may change with any minor input code change. This shouldn't
affect users except SWIG_TypePrettyName may output a different C/C++
typedef to a type - it's used mostly for showing errors when the type
passed to a function is wrong.
2022-09-29: olly
[PHP] Dynamic class properties are no longer supported by default.
Historically PHP has supported dynamic class properties and SWIG
has implemented them too (because we implement the magic __get(),
__set() and __isset() methods we need to include explicit
handling).
PHP 8.2 deprecates dynamic class properties - initially they'll
warn, and apparently they'll not work by default in PHP 9.0:
https://wiki.php.net/rfc/deprecate_dynamic_properties
In PHP code dynamic properties can be enabled for a class by
marking that class with the attribute `#[AllowDynamicProperties]`.
To follow this PHP change, in SWIG you now need to specify
`%feature("php:allowdynamicproperties", 1) Foo;` (or
`%feature("php:allowdynamicproperties", 1)` to enable it for
all wrapped classes). Unknown features are ignored, so you can add
it unconditionally and it'll work with older SWIG too.

2022-09-19: wsfulton
#1484 Fixes for class inheritance with the same name in different namespaces
such as:
namespace A { class Bar {}; }
namespace B { template<typename T, typename U> class Bar : public A::Bar {}; }
2022-09-19: wsfulton
#2316 Remove swig.spec file and srcrpm makefile target. These are very out of date
and don't seem to be used by RPM based Linux distributions which have their
own version of swig.spec.
2022-09-17: wsfulton
[Go, Guile, Racket, Scilab] Add throws typemaps for std::string so that thrown
string exception messages can be seen.
2022-09-17: wsfulton
[Racket] Add throws typemaps for char * so that thrown string exception
messages can be seen from Racket.
2022-09-17: wsfulton
[Javascript, Octave, R] Improve exceptions for %catches and exception
specifications for native types. String exception messages are shown as
the exception message instead of just the type of the exception.
2022-09-17: wsfulton
Add missing typecheck typemaps for std::auto_ptr and std::unique_ptr to
fix overloading when using these types.
2022-09-17: wsfulton
[Guile] Add error checking to SWIGTYPE and SWIGTYPE & in typemaps to prevent
seg faults when passing #nil to these parameter types.
2022-09-16: wsfulton
#999 Provide SWIGTYPE MOVE typemaps in swigmove.i for implementing full
move semantics when passing parameters by value.
2022-08-31: wsfulton
#999 Improve move semantics when using rvalue references.
The SWIGTYPE && input typemaps now assume the object has been moved.
These typemaps have been changed assuming that after the function call,
the rvalue reference parameter has been moved. The parameter's proxy class
that owns the C++ object thus has the underlying pointer set to null
so that the (moved from, but still valid) C++ object cannot be used again
and the object is additionally deleted.

2022-08-28: wsfulton
[Octave] SWIG now marshals a C/C++ NULL pointer into the null matrix, [].
SWIG has always marshalled the null matrix into a NULL pointer; this remains
and now we have consistency in representing a NULL pointer.
2022-08-26: wsfulton
[Racket] SWIG now marshals a C/C++ NULL pointer into a null value by calling
scheme_make_null(), so that scheme's null? is true for a NULL C/C++ pointer value.
2022-08-18: wsfulton
[Racket] Add support for std::unique_ptr in std_unique_ptr.i.

Add support for std::auto_ptr in std_auto_ptr.i.
2022-08-05: wsfulton
[D] Fix occasional undefined behaviour with inheritance hierarchies, particularly
when using virtual inheritance as the pointers weren't correctly upcast from derived
class to base class when stored in the base's proxy class.
2022-08-05: wsfulton
[D] Add support for std::unique_ptr in std_unique_ptr.i.

[Python] Add initialisers for additional members in PyHeapTypeObject
(builtin mode) for Python-3.11 - _ht_tpname, _spec_cache.
2022-07-30: wsfulton
C++20 has deprecated std::basic_string<>::reserve() and the C++11 method
std::basic_string<>::shrink_to_fit() is a replacement that can be used.
std_string.i and std_wstring.i provided wrappers for reserve with the following
template instantiations:
%template(string) std::basic_string<char>;
%template(wstring) std::basic_string<wchar_t>;
The reserve method is no longer wrapped, however the shrink_to_fit() method
can be used as an alternative from the target language (the generated wrappers
call reserve() instead if C++<=20).
Note that std::basic_string<>::reserve(size_t n) is still wrapped unchanged.

2022-07-30: wsfulton
[Tcl] Add support for std::unique_ptr in std_unique_ptr.i.

[Tcl] https://sourceforge.net/p/swig/bugs/977/
Fix handling of long long on 32-bit platforms. This fix raises
SWIG's minimum supported Tcl version to 8.4.0 (which was released
just under 20 years ago).
2022-07-26: olly
Fix incorrect operator precedence in preprocessor expressions.
2022-07-25: olly
Support for C++14 binary integer literals in preprocessor expressions.

#422 [Python] Fix mishandling of a Python class inheriting from
multiple SWIG-wrapped director classes.
2022-07-19: wsfulton
#692 [C#, Java, Perl, Python, Ruby] std::unique_ptr and std::auto_ptr typemaps
provided for inputs types in std_unique_ptr.i and std_auto_ptr.i.
Now these smart pointers can be used as input parameters to functions. A proxy
class instance transfers memory ownership of the underlying C++ object from the
proxy class to a smart pointer instance passed to the wrapped function.
2022-07-19: jschueller
[Python] #2314 Drop support for Python 3.2.
2022-07-19: olly

#999 Performance optimisation for parameters passed by value that are C++11 movable.
The C++ wrappers create a temporary variable for a parameter to be passed to a
function. This is initially default constructed and then copy assigned from the
instance being passed in from the target language. This is unchanged, however,
when the temporary variable is passed to the wrapped function, it is now done using
std::move. If the type is move constructible, the move constructor will be used
instead of the copy constructor.
2022-07-12: wsfulton
[Perl] Add std::auto_ptr support in std_auto_ptr.i library file.
2022-07-12: erezgeva
[Perl] Add std::unique_ptr support in std_unique_ptr.i library file.
2022-07-07: jmarrec
#1158 #2286 Add basic support for C++11 attributes. These are now
crudely ignored by SWIG's parser's tokeniser, which is better than
failing with a parse error.
2022-07-05: ianlancetaylor
[Go] #2245 Handle NULL pointers for string* conversions.
Rearrange generation of director methods and rename
receiver argument from p to swig_p.
2022-07-03: wsfulton
#999 Performance optimisation for directors for classes passed by value. The directorin
typemaps in the director methods now use std::move on the input parameter when
copying the object from the stack to the heap prior to the callback into the target
language, thereby taking advantage of move semantics if available.
2022-07-02: wsfulton
#1722 [C#, Java, Python, Ruby] Add std::unique_ptr support. Ported from std::auto_ptr.
Use the %unique_ptr(T) macro as follows for usage std::unique_ptr<T>. For example, for
a class called Klass:
%include "std_unique_ptr.i"
%unique_ptr(Klass)
Support is currently limited to only returning a std::unique_ptr from a function.
2022-06-29: wsfulton
#999 #1044 Enhance SWIGTYPE "out" typemaps to use std::move when copying
objects, thereby making use of move semantics when wrapping a function returning
by value if the returned type supports move semantics.
Wrapping functions that return move only types 'by value' now work out the box
without having to provide custom typemaps.
The implementation removed all casts in the "out" typemaps to allow the compiler to
appropriately choose calling a move constructor, where possible, otherwise a copy
constructor. The implementation also required modifying SwigValueWrapper to
change a cast operator from:
SwigValueWrapper::operator T&() const;
to
#if __cplusplus >=201103L
SwigValueWrapper::operator T&&() const;
#else
SwigValueWrapper::operator T&() const;
#endif
This is not backwards compatible for C++11 and later when using the valuewrapper feature
if a cast is explicitly being made in user supplied "out" typemaps. Suggested change
in custom "out" typemaps for C++11 and later code:
1. Try remove the cast altogether to let the compiler use an appropriate implicit cast.
2. Change the cast, for example, from static_cast<X &> to static_cast<X &&>, using the
__cplusplus macro if all versions of C++ need to be supported.
*** POTENTIAL INCOMPATIBILITY ***
2022-06-15: wsfulton
#2039 Add move assignment operator to SwigValueWrapper used by the
valuewrapper feature.
2022-06-04: sethrj
Enhance $typemap to support typemap attributes.
$typemap(method:attribute, typepattern)
For example:
%typemap(cstype, out="object") XClass "XClass"
%typemap(cscode) BarClass %{
$typemap(cstype:out, XClass) bar() {
return null;
}
which expands to
object bar() {
return null;
}

[Python] #2277 Define PY_SSIZE_T_CLEAN macro before #include "Python.h" as

./configure now enables C++11 and later C++ standards testing by default (when
running: 'make check').
The options to control this testing are the same:

[Python] #1635 The "autodoc" feature no longer overrides Doxygen comments
in the generated docstring.
If a "docstring" feature is present it will still override a Doxygen comment.
If the "autodoc" feature is also present, the combined "autodoc" and "docstring"
will override the Doxygen comment. If no "docstring" is present then the
"autodoc" feature will not be generated when there is a Doxygen comment.
This way the "autodoc" feature can be specified and used to provide documentation
for 'missing' Doxygen comments.

#1277 Fixes for the family of %interface macros, %interface,
%interface_impl and %interface_custom fixes for overloaded methods
in an inheritance chain.
When C++ methods are not able to be overloaded in a derived class,
such as when they differ by just const, or the target language
parameters types are identical even when the C++ parameter types

a warning. A %ignore is required to explicitly ignore one of the

SWIG should now reliably exit with status 0 if the run was
successful and status 1 if there was an error (or a warning and
-Werror was in effect).
Previously in some situations SWIG would try to exit with the
status set to the number of errors encountered, but that's
problematic - for example if there were 256 errors this would
result in exit status 0 on most platforms. Also some error
statuses have special meanings e.g. those defined by <sysexits.h>.
Also SWIG/Javascript tried to exit with status -1 in a few places
(which typically results in exit status 255).

[Python] #1951 Add Python variable annotations support.
Both function annotations and variable annotations are turned on using the
"python:annotations" feature. Example:
%feature("python:annotations", "c");
struct V {
float val;
};
The generated code contains a variable annotation containing the C float type:
class V(object):
val: "float" = property(_example.V_val_get, _example.V_val_set)
...
Python 3.5 and earlier do not support variable annotations, so variable
annotations can be turned off with a "python:annotations:novar" feature flag.
Example turning on function annotations but not variable annotations globally:
%feature("python:annotations", "c");
%feature("python:annotations:novar");
or via the command line:
-features python:annotations=c,python:annotations:novar

#1465 An invalid preprocessor expression is reported as a pair of
warnings with the second giving a more detailed message from the
expression evaluator. Previously SWIG prefixed the second message
with "Error:" - that was confusing as it's actually only a warning
by default so we've now dropped this prefix.
Before:
x.i:1: Warning 202: Could not evaluate expression '1.2'
x.i:1: Warning 202: Error: 'Floating point constant in preprocessor expression'

#1384 Fix a preprocessor expression evaluation bug. A
subexpression in parentheses lost its string/int type flag and

resulted in a preprocessor expression incorrectly evaluating as
zero. If -Wextra was in use you got a warning:

#1806 Remove support for the "command" encoder, which was mostly
intended for use in `%rename` - most uses can be achieved using
the "regex" encoder, so we recommend using that instead.
The "command" encoder suffers from a number of issues - as the
documentation for it admitted, "[it] is extremely slow compared to
all the other [encoders] as it involves spawning a separate process
and using it for many declarations is not recommended" and that it
"should generally be avoided because of performance
considerations".
But it's also not portable. The design assumes that `/bin/sh`
supports `<<<` but that's a bash-specific feature so it doesn't
work on platforms where `/bin/sh` is not bash - it fails on
Debian, Ubuntu and probably some other Linux distros, plus most
non-Linux platforms. Microsoft Windows doesn't even have a
/bin/sh as standard.
Finally, no escaping of the passed string is done, so it has
potential security issues (though at least with %rename the input
is limited to valid C/C++ symbol names).

[PHP] #2014 Throw PHP exceptions instead of using PHP errors
PHP exceptions can be caught and handled if desired, but if they
aren't caught then PHP exits in much the same way as it does for a
PHP error.
In particular this means parameter type errors and some other cases
in SWIG-generated wrappers now throw a PHP exception, which matches
how PHP's native parameter handling deals with similar situations.
`SWIG_ErrorCode()`, `SWIG_ErrorMsg()`, `SWIG_FAIL()` and `goto thrown;`
are no longer supported (these are really all internal implementation
details and none are documented aside from brief mentions in CHANGES
for the first three). I wasn't able to find any uses in user interface
files at least in FOSS code via code search tools.
If you are using these:
Use `SWIG_PHP_Error(code,msg);` instead of `SWIG_ErrorCode(code);
SWIG_ErrorMsg(msg);` (which will throw a PHP exception in SWIG >= 4.1
and do the same as the individual calls in older SWIG).
`SWIG_FAIL();` and `goto thrown;` can typically be replaced with
`SWIG_fail;`. This will probably also work with older SWIG, but
please test with your wrappers if this is important to you.

[Python] #1985 Fix memory leaks:
1. Python object references were being incorrectly retained by
SwigPyClientData, causing swig_varlink_dealloc() never to run / free
memory. SwigPyClientData_New() / SwigPyClientData_Del() were updated
to fix the object reference counting, causing swig_varlink_dealloc()
to run and the memory swig_varlink owns to be freed.
2. SwigPyClientData itself was not freed by SwigPyClientData_Del(),
causing another heap leak. The required free() was added to
SwigPyClientData_Del()
3. Fix reference counting/leak of python cached type query

SWIG now only use PHP's C API to implement its wrappers, and no
longer generates PHP code to define classes. The wrappers should
be almost entirely compatible with those generated before, but
faster and without some previously hard-to-fix bugs.
The main notable difference is SWIG no longer generates a .php
wrapper at all by default (only if %pragma(php) code=... or
%pragma(php) include=... are specified in the interface file).
This also means you need to load the module via extension=...
in php.ini, rather than letting the dl() in the generated
.php wrapper load it (but dl() has only worked for command-line
PHP for some years now).

[Octave] Fix exception raising for newer Octave versions
Since (at least) Octave 5.1.0, the Octave error() function now raises a C++ exception,
which if uncaught immediately exits a SWIG wrapper function, bypassing any cleanup code
that may appear after a "fail:" label. This patch adds a "try { ... } catch(...) { }"
block around the contents of SWIG wrapper functions to first execute the cleanup code
before rethrowing any exception raised. It is backward compatible with earlier versions
of Octave where error() does not raise an exception, which will still branch to the
"fail:" block to execute cleanup code if an error is encountered.
Note that the new "try { ... } catch(...) { }" block will localise any local variables
used in typemaps that were NOT declared through SWIG's %typemap(...) syntax, so it's
possible this could break existing SWIG wrappers which were implicitly sharing local
variables between typemaps. This can be fixed, however, by declaring local variables
which need to be shared between typemaps through SWIG's %typemap(...) syntax.

[Python] Fix method overloading of methods that take STL containers of different

%template(VectorInt) std::vector<int>;
%inline %{

string VectorOverload(vector<X> v);
string VectorOverload(vector<int> v);
%}
The following would incorrectly fail:
s = VectorOverload([1, 2, 3])
With:
Traceback (most recent call last):
File "runme3.py", line 20, in <module>
ret = VectorOverload([1, 2, 3])
TypeError: Wrong number or type of arguments for overloaded function 'VectorOverload'.
Possible C/C++ prototypes are:
VectorOverload(std::vector< Number,std::allocator< Number > >)
VectorOverload(std::vector< int,std::allocator< int > >)
The problem was due to some error handling that was not cleared during typechecking.
In this case an error was not cleared when the elements in the list failed the
typecheck for converting to X. Only occurs in Python 3+.
In some combinations of overloaded methods, the following type of error message would
occur:
RuntimeError: in sequence element 0
The above exception was the direct cause of the following exception:
Traceback (most recent call last):

[Java] std::vector improvements for types that do not have a default constructor.
The std::vector wrappers have been changed to work by default for elements that are
not default insertable, i.e. have no default constructor. This has been achieved by
not wrapping:
vector(size_type n);
Previously the above had to be ignored via %ignore.
If the above constructor is still required it can be added back in again via %extend:
%extend std::vector {
vector(size_type count) { return new std::vector< T >(count); }
}
Alternatively, the following wrapped constructor could be used as it provides near-enough
equivalent functionality:
vector(jint count, const value_type& value);

to obtain a back-reference to the container by the wrapper to the element in the Python

Python static method wrapper changes
- Static method wrappers were using the 'fastproxy' approach by default.
This is inconsistent with instance method wrappers. The fastproxy approach
is now turned off by default to be consistent with instance methods.
Static method wrappers can now also be controlled using the -fastproxy and
-olddefs options.
Example:
struct Klass {
static int statmethod(int a = 2);
};
generates by default:
class Klass(object):
...
@staticmethod
def statmethod(a=2):
return _example.Klass_statmethod(a)
instead of the following (which can be restored by using -fastproxy):
class Klass(object):
...
statmethod = staticmethod(_example.Klass_statmethod)
- Modernise wrappers for static methods to use decorator syntax - @staticmethod.
- Add missing runtime test for static class methods and using the actual class method.

Global functions previously generated two definitions, eg:

generated by default and if the -fastproxy command line option is used, just the second
definition is generated. The second definition is faster as it avoids the proxy Python
method as it calls the low-level C wrapper directly. Using both -fastproxy and -olddefs
command line options will restore the previously generated code as it will generate both
method definitions.
With this change, the wrappers for global C/C++ functions and C++ class methods now work
in the same way wrt to generating just a proxy method by default and control via
-fastproxy/-olddefs options.

2018-12-16: wsfulton
[Python] #848 #1343 The module import logic has changed to stop obfuscating real ImportError
problems. Only one import of the low-level C/C++ module from the pure Python module is
attempted now. Previously a second import of the low-level C/C++ module was attempted
after an ImportError occurred and was done to support 'split modules'. A 'split module' is
a configuration where the pure Python module is a module within a Python package and the
low-level C/C++ module is a global Python module. Now a 'split module' configuration is
no longer supported by default. This configuration can be supported with a simple
customization, such as:
%module(package="mypackage", moduleimport="import $module") foo
or if using -builtin:
%module(package="mypackage", moduleimport="from $module import *") foo
instead of
%module(package="mypackage") foo
See the updated Python chapter titled "Location of modules" in the documentation.

2018-11-28: wsfulton
[Python] When using -builtin, the two step C-extension module import is now
one step and the wrapped API is only available once and not in an underlying
module attribute like it is without -builtin. To understand this, consider a
module named 'example' (using: %module example). The C-extension is compiled into
a Python module called '_example' and a pure Python module provides the actual
API from the module called 'example'. It was previously possible to additionally
access the API from the module attribute 'example._example'. The latter was an
implementation detail and is no longer available. It shouldn't have been used, but
if necessary it can be resurrected using the moduleimport attribute described in the
Python chapter of the documentation. If both modules are provided in a Python
package, try:
%module(moduleimport="from . import _example\nfrom ._example import *") example
or more generically:
%module(moduleimport="from . import $module\nfrom .$module import *") example
and if both are provided as global modules, try:
%module(moduleimport="import _example\nfrom _example import *") example
or more generically:
%module(moduleimport="import $module\nfrom $module import *") example
The module import code shown will appear in the example.py file.

[Python] #1282 Make generated module runnable via python -m (PEP 366 conforming)
Previously any SWIG generated modules in a package would fail with an ImportError
when using 'python -m' for example 'python -m mypkg.mymodule'.
This fix also allows the SWIG generated module to be placed into a directory and
then renamed __init__.py to convert the module into a package again. This ability
stopped working in swig-3.0.9. However, only Python 2.7 or 3.3 and later work. If
Python 3.2 support is needed, use moduleimport in %module to customise the import
code.

[Python] #1340 Remove -outputtuple and -nooutputtuple command line options.

typemap implementations.
It unclear why a tuple instead of a list return type is needed and

the SWIG Python command line options for SWIG 4.

[Python] #1261 #1340 Turn on many optimisation options by default and rationalise the
number of command line options.
There were an unnecessary number of command line options and many of these have now
been removed in a drive for simplification. Some were needed to support older versions
of Python (2.6 and earlier).
Many of the options could be turned on individually and when using -O. Previously -O
resulted in turning on a set of options:
-modern -fastdispatch -nosafecstrings -fvirtual -noproxydel
-fastproxy -fastinit -fastunpack -fastquery -modernargs -nobuildnone
Now -O results in turning on this reduced set:
-fastdispatch -fastproxy -fvirtual
The following options are now on by default, a deprecated warning is displayed if they
are used:
-fastinit Class initialisation code done in C/C++ rather than in Python code.
-fastquery Python dictionary used for lookup of types.
-fastunpack Faster unpacking of function arguments in C/C++ wrappers.
-modern Use Python 2.3 features such as object and property.
-modernargs Use Python 2.3 C APIs for unpacking arguments in tuples.
-noproxydel Stop generating a proxy __del__ method for backwards compatiblity.
-safecstrings No discernable difference
The following options have been removed altogether:
-aliasobj0
-buildnone
-classptr
-new_repr
-newrepr
-noaliasobj0
-nobuildnone
-nocastmode
-nodirvtable
-noextranative
-nofastinit

Issue #1098. Fix overloading of shared_ptr with underlying pointer types, eg:
void m(std::shared_ptr<T> p);
void m(T &p);
void m(T *p);
Only the first method is wrapped and the others are ignored/shadowed.
The implementation is done via a new attribute in the 'typecheck' typemap called
'equivalent'. If specified, it must contain the equivalent pointer type for overloading
and can only be used for the special SWIG_TYPECHECK_POINTER precedence level.
The shared_ptr 'typecheck' typemaps have been modified accordingly.
Here is a simplified version:
%typemap(typecheck, precedence=SWIG_TYPECHECK_POINTER, equivalent="T *")
T,
T CONST &,
T CONST *,
T *CONST&,
std::shared_ptr< T >,
std::shared_ptr< T > &,
std::shared_ptr< T > *,
std::shared_ptr< T > *&
{ ... }
Overloading with any of these types will result in SWIG ignoring all but the first
overloaded method by default. Without the 'equivalent' attribute, wrapping the overloaded
methods resulted in types being shadowed (scripting languages) or code that did not
compile (statically typed languages).

Issue #1051. %template scope enforcement and class definition fixes.
The scoping rules around %template have been specified and enforced.
The %template directive for a class template is the equivalent to an
explicit instantiation of a C++ class template. The scope for a valid
%template instantiation is now the same as the scope required for a
valid explicit instantiation of a C++ template. A definition of the
template for the explicit instantiation must be in scope where the
instantiation is declared and must not be enclosed within a different
namespace.
For example, a few %template and C++ explicit instantiations of std::vector
are shown below:
// valid
namespace std {
%template(vin) vector<int>;
template class vector<int>;
}
// valid
using namespace std;
%template(vin) vector<int>;
template class vector<int>;
// valid
using std::vector;
%template(vin) vector<int>;
template class vector<int>;
// ill-formed
namespace unrelated {
using std::vector;
%template(vin) vector<int>;
template class vector<int>;
}
// ill-formed
namespace unrelated {
using namespace std;
%template(vin) vector<int>;
template class vector<int>;
}
// ill-formed
namespace unrelated {
namespace std {
%template(vin) vector<int>;
template class vector<int>;
}
}
// ill-formed
namespace unrelated {
%template(vin) std::vector<int>;
template class std::vector<int>;
}
When the scope is incorrect, an error now occurs such as:
cpp_template_scope.i:34: Error: 'vector' resolves to 'std::vector' and
was incorrectly instantiated in scope 'unrelated' instead of within scope 'std'.
Previously SWIG accepted the ill-formed examples above but this led to
numerous subtle template scope problems especially in the presence of
using declarations and using directives as well as with %feature and %typemap.
Actually, a valid instantiation is one which conforms to the C++03
standard as C++11 made a change to disallow using declarations and
using directives to find a template.
// valid C++03, ill-formed C++11
using std::vector;
template class vector<int>;
Similar fixes for defining classes using forward class references have
also been put in place. For example:
namespace Space1 {
struct A;
}
namespace Space2 {
struct Space1::A {
void x();
}
}
will now error out with:
cpp_class_definition.i:5: Error: 'Space1::A' resolves to 'Space1::A' and
was incorrectly instantiated in scope 'Space2' instead of within scope 'Space1'.
Previously some symbols would have been instantiated in the wrong scope and led
to lots of scope problems involving SWIG typemaps, features, renames etc.
You will need to correct the scope used in other SWIG directives which do not
support 'using declarations' and 'using directives'. For example, if you previously had:
%rename(Zap) vector<int>::clear;
using namespace std;
%template(VectorInt) vector<int>;
Prior versions of SWIG incorrectly instantiated vector<int> in the global namespace
and so the %rename matched. Now the template is instantiated in the correct namespace,
so is fully qualified as std::vector<int>. The other SWIG directives need correcting as
they do not follow 'using declarations' and 'using directives'. Change it to:
%rename(Zap) std::vector<int>::clear;
using namespace std;
%template(vin) vector<int>;

For templates only, the template parameters are fully resolved when
handling typemaps. Without this, it is too hard to have decent rules
to apply typemaps when parameter types are typedef'd and template
parameters have default values.
Fixes %clear for typedefs in templates, eg:
%typemap("in") XXX<int>::Long "..."
template typename<T> struct XXX {
typedef long Long;
};
%clear XXX<int>::Long;
as the typemap was previously incorrectly stored as a typemap for long
instead of XXX<int>::Long.

[Python] fix and improve default argument handling:
1. Fix negative octals. Currently not handled correctly by `-py3`
(unusual case, but incorrect).
2. Fix arguments of type "octal + something" (e.g. `0640 | 04`).
Currently drops everything after the first octal. Nasty!
3. Fix bool arguments "0 + something" (e.g. `0 | 1`) are always
"False" (unusual case, but incorrect).
4. Remove special handling of "TRUE" and "FALSE" from
`convertValue` since there's no reason these have to match
"true" and "false".
5. Remove the Python 2 vs. Python 3 distinction based on the
`-py3` flag. Now the same python code is produced for default
arguments for Python 2 and Python 3. For this, octal default
arguments, e.g. 0644, are now wrapped as `int('644', 8)`. This
is required, as Python 2 and Python 3 have incompatible syntax
for octal literals.

[Python] Fix handling of rich comparisons when wrapping overloaded operators:
operator< operator<= operator> operator>= operator== operator!=
Previously a TypeError was always thrown if the type was not correct. NotImplemented
is now returned from these wrapped functions if the type being compared with is
not correct. The subsequent behaviour varies between different versions of Python
and the comparison function being used, but is now consistent with normal Python
behaviour. For example, for the first 4 operator overloads above, a TypeError
'unorderable types' is thrown in Python 3, but Python 2 will return True or False.
NotImplemented should be returned when the comparison cannot be done, see PEP 207 and
https://docs.python.org/3/library/constants.html#NotImplemented
Note that the bug was only present when overloaded operators did not also have a
function overload.

[Java] #842 Extend from java.util.AbstractList<> and implement java.util.RandomAccess for
std::vector wrappers. This notably allows to iterate over wrapped vectors in a natural way.
Note that boxed types are now used in the Java layer when wrapping vector of C primitive
types, for example. This may introduce some subtle incompatibilities due to some
differences in how Java converts boxed types and unboxed types. For example,
int i=0;
double d1 = i; // ok
Double d2 = i; // error: incompatible types: int cannot be converted to Double
This can be a problem when calling the add and set functions. A suggested backwards
compatible workaround is to use something like (shown for std::vector<double>:
#if defined(SWIGJAVA)
// Add in old api that uses non-boxed types
%extend std::vector<double> {
%proxycode %{
public void add(double x) {
add(Double.valueOf(x));
}
public void set(int i, double val) {
set(i, Double.valueOf(val));
}
%}

[Octave] add support for version 4.2
- The Octave API now uses some C++11 features. It is recommended to use

wrapper code, as mkoctfile will ensure the correct C++ compiler/options
are used. Otherwise, the value of `mkoctfile -p CXX` should be parsed
for any -std=* flags which might be present.
- Octave has dropped support for << and >> operators, so SWIG now
ignores them.
- The Octave error() function now raises C++ exceptions to propagate
Octave errors, so %exception directives may need to be modified.
For convenience the SWIG_RETHROW_OCTAVE_EXCEPTIONS macro can be used
to rethrow any Octave exceptions for Octave itself to handle, e.g.:
try {
$action // may call error()
}
SWIG_RETHROW_OCTAVE_EXCEPTIONS // error() exceptions are rethrown
catch(...) {
... // all other exceptions

substantially so you need to use -php7 to specify you want PHP7
compatible wrappers. The default extension for generated wrappers
is now .cxx (to match SWIG's default for every other language - to
generate foo_wrap.cpp you can run SWIG with -cppext cpp). Fixes
issue #571.
As part of this change, the language subdirectory for PHP5 has
changed from "php" to "php5" - if you are making use of the search
path feature where the language subdirectory of each directory
is also searched, you'll need to update your bindings. A simple
fix which works for older and newer SWIG is to add a symlink:

template<typename T> struct X {

%rename(woohoo) W::Woo; // fix now overrides above %rename
template<typename T> struct W {
W Woo();
...
};
%template(Wint) W<int>;
The above also introduces a possibly unexpected change. Many of the STL containers
provided by SWIG use %rename to rename some methods, eg in std::vector, push_back
is renamed to add in Java. Previously this intended rename did not happen when using
using global %rename rules and the method would remain as push_back, but is now
renamed to add. Some more info in issue #856.

[Python] More flexible python builtin slots for overloaded C++ function.
The closure names used for builtin slots are mangled with their functype so
that overloaded C++ method names can be used for multiple slots.
For example:
%feature("python:slot", "mp_subscript", functype="binaryfunc") SimpleArray::__getitem__;
%feature("python:slot", "sq_item", functype="ssizeargfunc") SimpleArray::__getitem__(Py_ssize_t n);
will generate closures:
SWIGPY_SSIZEARGFUNC_CLOSURE(_wrap_SimpleArray___getitem__) /* defines _wrap_SimpleArray___getitem___ssizeargfunc_closure */
SWIGPY_BINARYFUNC_CLOSURE(_wrap_SimpleArray___getitem__) /* defines _wrap_SimpleArray___getitem___binaryfunc_closure */

Patch #730 - Fix %implicitconv for overloaded functions when using
-castmode or -fastdispatch options.
The result is that in all overload cases where there are multiple possibilities
with the same number of arguments, the dispatch function will first check for
exact (aka non implicit) matches, and then subsequently check for implicit
casting matches. This was already happening in the normal dispatch situation,
and in the -fastdispatch case two passes through the candidates were happening,
just with SWIG_POINTER_IMPLICIT_CONV always set. After this patch, it is not set
on the first pass, and then set on the second pass.

Patch #727 - Add support for C++11 type aliasing.
Version 3.0.10 (12 Jun 2016)
============================
2016-06-06: mromberg
[Python] Patch #698. Add support for -relativeimport for python 2.7, so -py3 is no
longer also required for relative import support.
2016-06-05: mromberg
[Python] Patch #694 - Fix package import regressions introduced in swig-3.0.9.
1) The code in 3.0.9 did not fall back to 'import _foo' if 'import bar._foo' failed
(assuming bar.foo was the main module). Every place _foo is imported now first tries
it from the package where foo was found and if that fails tries _foo as a global module.
2) The separate block of Python code that injected code to pull in the attributes
from _foo when -builtin is used made use of the -py3 switch to either do
'from ._foo import *' or "from _foo import *". This block of code no longer does this
and instead checks the Python version at runtime to switch between the two syntaxes.
In summary, swig-3.0.10 has been modified to ease the creation of wrapper modules
that can be fully made part of a Python package. SWIG no longer
assumes the dynamically linked C module is a global module.
The dynamic module can now be placed into either the same package as the pure Python
module or as a global module. Both locations are used by the Python wrapper to
locate the C module.
However, this could cause a backwards incompatibility with some code
that was relying on the ability of "from package import _module" to
pull attributes out of the package directly. If your code populates a
module (which is also a package) with attributes that are SWIG
generated modules which were not loaded in a conventional way,
swig-3.0.8 and earlier may have worked due to 'from package import
_module' bypassing a real import and pulling your module in as an
attribute. This will no longer work. Since this is not a common (or
even recommended) practice, most folk should not be affected.

[Python] Fixes for conversion of signed and unsigned integer types:
No longer check for PyInt objects in Python3. Because PyInt_Check
and friends are #defined to the corresponding PyLong methods, this
had caused errors in Python3 where values greater than what could be
stored in a long were incorrectly interpreted as the value -1 with
the Python error indicator set to OverflowError. This applies to
both the conversions PyLong->long and PyLong->double.
Conversion from PyLong to long, unsigned long, long long, and
unsigned long long now raise OverflowError instead of TypeError in
both Python2 and Python3 for PyLong values outside the range
expressible by the corresponding C type. This matches the existing
behavior for other integral types (signed and unsigned ints, shorts,
and chars), as well as the conversion for PyInt to all numeric
types. This also indirectly applies to the size_t and ptrdiff_t
types, which depend on the conversions for unsigned long and long.

[Ruby] STL ranges and slices fixes.
Ruby STL container setting slices fixes:
Setting an STL container wrapper slice better matches the way Ruby
arrays work. The behaviour is now the same as Ruby arrays. The only
exception is the default value used when expanding a container
cannot be nil as this is not a valid type/value for C++ container
elements.
Obtaining a Ruby STL container ranges and slices fixes:
Access via ranges and slices now behave identically to Ruby arrays.
The fixes are mostly for out of range indices and lengths.
- Zero length slice requests return an empty container instead of nil.
- Slices which request a length greater than the size of the container
no longer chop off the last element.
- Ranges which used to return nil now return an empty array when the
the start element is a valid index.
Ruby STL container negative indexing support improved.
Using negative indexes to set values works the same as Ruby arrays, eg
%template(IntVector) std::vector<int>;
iv = IntVector.new([1,2,3,4])
iv[-4] = 9 # => [1,2,3,9]
iv[-5] = 9 # => IndexError

[Java] Fix potential security exploit in generated Java classes.

https://www.usenix.org/conference/woot15/workshop-program/presentation/peles.
In the unlikely event that you are relying on these members being serializable,

SWIG-3.0.6 gave a 'Line indented less than expected' error instead of truncating

Support for special variable expansion in typemap attributes. Example usage expansion
in the 'out' attribute (C# specific):
%typemap(ctype, out="$*1_ltype") unsigned int& "$*1_ltype"
is equivalent to the following as $*1_ltype expands to 'unsigned int':
%typemap(ctype, out="unsigned int") unsigned int& "unsigned int"
Special variables can be used within special variable macros too. Example usage expansion:
%typemap(cstype) unsigned int "uint"
%typemap(cstype, out="$typemap(cstype, $*1_ltype)") unsigned int& "$typemap(cstype, $*1_ltype)"
Special variables are expanded first and hence the above is equivalent to:
%typemap(cstype, out="$typemap(cstype, unsigned int)") unsigned int& "$typemap(cstype, unsigned int)"
which then expands to:
%typemap(cstype, out="uint") unsigned int& "uint"

[Python] Add new feature "python:cdefaultargs" to control default argument
code generation. By default, SWIG attempts to convert C/C++ default argument values
into Python values and generates code into the Python layer with these values.
Recent versions of SWIG are able to convert more of these values, however, the
new behaviour can be circumvented if desired via this new feature, such that
the default argument values are obtained from the C layer and not the Python layer.
For example:
struct CDA {
int fff(int a = 1, bool b = false);
};
The default code generation in the Python layer is:
class CDA(_object):
...
def fff(self, a=1, b=False):
return _default_args.CDA_fff(self, a, b)
Adding the feature:
%feature("python:cdefaultargs") CDA::fff;
Results in:
class CDA(_object):
...
def fff(self, *args):
return _default_args.CDA_fff(self, *args)
Some code generation modes, eg -builtin and -fastproxy, are unaffected by this as
the default values are always obtained from the C layer.

C++11 support initially developed as C++0x support by Matevz Jekovec as a Google Summer of Code
project has been further extended. The C++11 support is comprehensive, but by no means complete
or without limitations. Full details for each new feature in C++11 is covered in the
CPlusPlus11.html chapter in the documentation which is included in SWIG and also available
online at https://www.swig.org/Doc3.0/CPlusPlus11.html.
2014-03-14: v-for-vandal
[Lua] Numerous Lua improvements:
1. %nspace support has been added. Namespaces are mapped to tables in the module, with the same
name as the C++ namespace.
2. Inheritance is now handled differently. Each class metatable keeps a list of class bases instead
of merging all members of all bases into the derived class.
3. The new metatables result in differences in accessing class members. For example:
%module example
struct Test {
enum { TEST1 = 10, TEST2 = 20 };
static const int ICONST = 12;
};
Now this can be used as follows:
print(example.Test.TEST1)
print(example.Test.ICONST)
The old way was:
print(example.Test_TEST1)
print(example.Test_ICONST)
4. The special class metatable member ".constructor" was removed. Now SWIG generates the proxy
function by itself and assigns it directly to the class table "__call" method.
5. eLua should also now support inheritance.
6. 'const' subtable in eLua is considered deprecated.
Changes in behaviour:
a. You can no longer assign to non-existing class members in classes without a __setitem__ method.
It will cause a Lua error.
b. You can no longer iterate over a module table and copy everything into the global namespace.
Actually, this was never the case, but it is now explicitly prohibited.
c. Now changing a base class will immediately affect all derived classes.
d. There might be some issues with inheritance. Although the bases iteration scheme is the same
as was used for merging base classes into derived one, some unknown issues may arise.
The old metatable behaviour can be restored by using the -no-old-metatable-bindings option.

2014-03-06: wsfulton
[Python] Change in default behaviour wrapping C++ bool. Only a Python True or False
will now work for C++ bool parameters. This fixes overloading bool with other types.
Python 2.3 minimum is now required for wrapping bool.
When wrapping:
const char* overloaded(bool value) { return "bool"; }
const char* overloaded(int value) { return "int"; }
Previous behaviour:
>>> overloaded(False)
'int'
>>> overloaded(True)
'int'
>>> overloaded(0)
'int'
Now we get the expected behaviour:
>>> overloaded(False)
'bool'
>>> overloaded(0)
'int'
The consequence is when wrapping bool in non-overloaded functions:
const char* boolfunction(bool value) { return value ? "true" : "false"; }
The previous behaviour was very Pythonic:
>>> boolfunction("")
'false'
>>> boolfunction("hi")
'true'
>>> boolfunction(12.34)
'true'
>>> boolfunction(0)
'false'
>>> boolfunction(1)
'true'
Now the new behaviour more along the lines of C++ due to stricter type checking. The
above calls result in an exception and need to be explicitly converted into a bool as
follows:
>>> boolfunction(0)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: in method 'boolfunction', argument 1 of type 'bool'
>>> boolfunction(bool(0))
'false'
The old behaviour can be resurrected by passing the -DSWIG_PYTHON_LEGACY_BOOL command line
parameter when executing SWIG. Typemaps can of course be written to customise the behaviour
for specific parameters.

[Java] Add support for the cdata library.
2014-02-08: vkalinin
Nested class support added. This primarily allows SWIG to properly parse nested
classes and keep the nested class information in the parse tree. Java and C#
have utilised this information wrapping the C++ nested classes as Java/C#
nested classes. The remaining target languages ignore nested classes as in
previous versions. Help is needed by users of these remaining languages to
design how C++ nested classes can be best wrapped. Please talk to us on the
swig-devel mailing list if you think you can help.
Previously, there was limited nested class support. Nested classes were treated
as opaque pointers. However, the "nestedworkaround" feature provided a way to
wrap a nested class as if it was a global class. This feature no longer exists
and is replaced by the new "flatnested" feature. This effectively does the same
thing with less manual code to be written. Please see the 'Nested classes'
section in the documentation in SWIGPlus.html if you were previously using this
feature.
SWIG now parses the contents of nested classes where previously it did not. You
may find that you will need to make adjustments to your interface file as
effectively extra code is being wrapped.

[Python] SF Bug #1297
Resolve several issues related to python imports.
For example, it's now possible to import modules having the same module
names, but belonging in different packages.
From the user's viewpoint, this patch gives a little bit more control on
import statements generated by SWIG. The user may choose to use relative
or absolute imports.
Some details:
- we (still) generate import statements in the form 'import a.b.c' which
corresponds to absolute imports in python3 and (the only available)
ambiguous one in python2.
- added -relativeimport option to use explicit relative import syntax
(python3),
The "Python Packages" section in the documentation discusses how to work
with importing packages including the new -relativeimport command line option.

2013-12-18: ianlancetaylor
[Go] Don't require that Go environment variables be set
when running examples or testsuite when using Go 1 or
later.
2013-12-17: ianlancetaylor
[Go] Remove -longsize option (for backward compatibility,
ignore it if seen).
2013-12-17: ianlancetaylor
[Go] Add -go-pkgpath option.
2013-12-16: ianlancetaylor
[Go] Update for Go 1.2 release. Add support for linking
SWIG code directly into executable, rather than using a
shared library.
2013-12-13: ianlancetaylor
[Go] Add SWIG source file name as comments in generated
files. This can be used by Go documentation tools.
2013-12-12: jleveque
[Lua] Fix typo (wchar instead of wchar_t) which made wchar.i
for Lua useless.
2013-12-12: vmiklos
[PHP] PHP's peculiar call-time pass-by-reference feature was
deprecated in PHP 5.3 and removed in PHP 5.4, so update the REF
typemaps in phppointers.i to specify pass-by-reference in the
function definition. Examples/php/pointer has been updated
accordingly.
2013-12-12: olly
[PHP] The usage of $input in PHP directorout typemaps has been
changed to be consistent with other languages. The typemaps
provided by SWIG have been updated accordingly, but if you
have written your own directorout typemaps, you'll need to
update $input to &$input (or make equivalent changes).

[C#, Java, Python] Add std_auto_ptr.i defining typemaps for returning std::auto_ptr<>.
2013-11-09: wsfulton
[C#] Apply patch #79 from Brant Kyser
- Remove using directives from the generated C# code and fully qualify the use of all .NET
framework types in order to minimize potential name collisions from input files defining
types, namespace, etc with the same name as .NET framework members.
- Globally qualify the use of .NET framework types in the System namespace
- Remove .NET 1.1 support, .NET 2 is the minimum for the C# module
This is a potential backwards compatibility break if code has been added relying on these using
statements that used to be generated:
using System;
using System.Runtime.InteropServices;
The quick fix to add these back in is to add the -DSWIG2_CSHARP command line option when
executing SWIG. See CSharp.html documentation for more info.

Merge in C++11 support from the gsoc2009-matevz branch where Matevz Jekovec first
started the C++0x additions. Documentation of the C++11 features supported is in a
new Chapter of the documentation, "SWIG and C++11" in Doc/Manual/CPlusPlus11.html.

===========================
2014-01-16: wsfulton
[PHP] Fix compilation error in ZTS mode (64 bit windows) due to incorrect placement
of TSRMLS_FETCH() in SWIG_Php_GetModule() as reported by Mark Dawson-Butterworth.
2014-01-13: kwwette
[Octave] update support to Octave version 3.8.0
- Octave 3.8.0 no longer defines OCTAVE_API_VERSION_NUMBER, but 3.8.1
will define OCTAVE_{MAJOR,MINOR,PATCH}_VERSION instead: see
http://hg.savannah.gnu.org/hgweb/octave/rev/b6b6e0dc700e
So we now use a new macro SWIG_OCTAVE_PREREQ(major,minor,patch) to
enable features requiring Octave version major.minor.patch or later.
For Octave versions prior to 3.8.1, we reconstruct values for
OCTAVE_{MAJOR,MINOR,PATCH}_VERSION based on OCTAVE_API_VERSION_NUMBER,
extracted from Octave's ChangeLogs. An additional hack is needed to
distinguish between Octave <= 3.2.x and 3.8.0, neither of which define
OCTAVE_API_VERSION_NUMBER.
- Octave 3.8.0 deprecates symbol_table::varref(), so remove its use
for this and future versions of Octave.
- Octave 3.8.0 removes octave_value::is_real_nd_array(), used in
octave_swig_type::dims(). Its use is not required here, so remove it.
- Retested against Octave versions 3.0.5, 3.2.4, 3.4.3, 3.6.4, and 3.8.0.
- Updated Octave documentation with tested Octave versions, and added a
warning against using versions <= 3.x.x, which are no longer tested.
2013-12-22: wsfulton
C++11 support for new versions of erase and insert in the STL containers.
The erase and insert methods in the containers use const_iterator instead
of iterator in C++11. There are times when the methods wrapped must match
the parameters exactly. Specifically when full type information for
template types is missing or SWIG fails to look up the type correctly,
for example:
%include <std_vector.i>
typedef float Real;
%template(RealVector) std::vector<Real>;
SWIG does not find std::vector<Real>::iterator because %template using
typedefs does not always work and so SWIG doesn't know if the type is
copyable and so uses SwigValueWrapper<iterator> which does
not support conversion to another type (const_iterator). This resulted
in compilation errors when using the C++11 version of the containers.
Closes #73

[Lua] Pull Git patch #62.
1) Static members and static functions inside class can be accessed as
ModuleName.ClassName.FunctionName (MemberName respectively). Old way such as
ModuleName.ClassName_FunctionName still works.
2) Same goes for enums inside classes: ModuleName.ClassName.EnumValue1 etc.
2013-09-12: wsfulton
[UTL] Infinity is now by default an acceptable value for type 'float'. This fix makes
the handling of type 'float' and 'double' the same. The implementation requires the
C99 isfinite() macro, or otherwise some platform dependent equivalents, to be available.
Users requiring the old behaviour of not accepting infinity, can define a 'check' typemap
wherever a float is used, such as:
%typemap(check,fragment="<float.h>") float, const float & %{
if ($1 < -FLT_MAX || $1 > FLT_MAX) {
SWIG_exception_fail(SWIG_TypeError, "Overflow in type float");
}
%}

[Python] %implicitconv is improved for overloaded functions. Like in C++, the methods
with the actual types are considered before trying implicit conversions. Example:
%implicitconv A;
struct A {
A(int i);
};
class CCC {
public:
int xx(int i) { return 11; }
int xx(const A& i) { return 22; }
};
The following python code:
CCC().xx(-1)
will now return 11 instead of 22 - the implicit conversion is not done.

[Python] Fix clang++ warning in generated wrapper code.
2013-08-16: wsfulton
[Python] %implicitconv will now accept None where the implicit conversion takes a C/C++ pointer.
Problem highlighted by Bo Peng. Closes SF patch #230.
2013-08-07: wsfulton
[Python] SF Patch #326 from Kris Thielemans - Remove SwigPyObject_print and SwigPyObject_str and
make the generated wrapper use the default python implementations, which will fall back to repr
(for -builtin option).
Advantages:
- it avoids the swig user having to jump through hoops to get print to work as expected when
redefining repr/str slots.
- typing the name of a variable on the python prompt now prints the result of a (possibly redefined)
repr, without the swig user having to do any extra work.
- when redefining repr, the swig user doesn't necessarily have to redefine str as it will call the
redefined repr
- the behaviour is exactly the same as without the -builtin option while requiring no extra work
by the user (aside from adding the %feature("python:slot...) statements of course)
Disadvantage:
- default str() will give different (but clearer?) output on swigged classes
2013-07-30: wsfulton
[Python, Ruby] Fix #64 #65: Missing code in std::multimap wrappers. Previously an instantiation
of a std::map was erroneously required in addition to an instantiation of std::multimap with the
same template parameters to prevent compilation errors for the wrappers of a std::multimap.

[R] Change types file to allow for SEXP return values
2013-07-05: wsfulton
[Python] Add %pythonbegin directive which works like %pythoncode, except the specified code is
added at the beginning of the generated .py file. This is primarily needed for importing from
__future__ statements required to be at the very beginning of the file. Example:
%pythonbegin %{
from __future__ import print_function
print("Loading", "Whizz", "Bang", sep=' ... ')

[Python] Add SWIG_PYTHON_INTERPRETER_NO_DEBUG macro which can be defined to use the Release version
of the Python interpreter in Debug builds of the wrappers. The Visual Studio .dsp example
files have been modified to use this so that Debug builds will now work without having
to install or build a Debug build of the interpreter.

Fix ccache-swig internal error bug due to premature file cleanup.
Fixes SF bug 1319 which shows up as a failure in the ccache tests on
Debian 64 bit Wheezy, possibly because ENABLE_ZLIB is defined.
This is a corner case which will be hit when the maximum number of files
in the cache is set to be quite low (-F option), resulting in a cache miss.

2013-04-28: gjanssens
[Guile] Updates in guile module:
- Add support for guile 2.0
- Drop support for guile 1.6
- Drop support for generating wrappers using guile's gh interface.

- Deprecate -gh and -scm options. They are no longer needed.
A warning will be issued when these options are still used.
- Fix all tests and examples to have a successful travis test
2013-04-18: wsfulton
Apply Patch #36 from Jesus Lopez to add support for $descriptor() special variable macro expansion
in fragments. For example:
%fragment("nameDescriptor", "header")
%{

which will generate into the wrapper if the fragment is used:
static const char *nameDescriptor = "SWIGTYPE_Name";

[C#, Java, D] Fix seg fault in SWIG using directors when class and virtual method names are

2013-02-19: kwwette
Fix bug in SWIG's handling of qualified (e.g. const) variables of array type. Given the typedef
a(7).q(volatile).double myarray // typedef volatile double[7] myarray;
the type
q(const).myarray // const myarray
becomes
a(7).q(const volatile).double // const volatile double[7]
Previously, SwigType_typedef_resolve() produces the type
q(const).a(7).q(volatile).double // non-sensical type
which would never match %typemap declarations, whose types were parsed correctly.
Add typemap_array_qualifiers.i to the test suite which checks for the correct behaviour.
2013-02-18: wsfulton
Deprecate typedef names used as constructor and destructor names in %extend. The real
class/struct name should be used.
typedef struct tagEStruct {
int ivar;
} EStruct;
%extend tagEStruct {
EStruct() // illegal name, should be tagEStruct()
{
EStruct *s = new EStruct();
s->ivar = ivar0;
return s;
}
~EStruct() // illegal name, should be ~tagEStruct()
{
delete $self;
}
}
For now these trigger a warning:
extend_constructor_destructor.i:107: Warning 522: Use of an illegal constructor name 'EStruct' in
%extend is deprecated, the constructor name should be 'tagEStruct'.
extend_constructor_destructor.i:111: Warning 523: Use of an illegal destructor name 'EStruct' in
%extend is deprecated, the destructor name should be 'tagEStruct'.
These %extend destructor and constructor names were valid up to swig-2.0.4, however swig-2.0.5 ignored
them altogether for C code as reported in SF bug #1306. The old behaviour of using them has been
restored for now, but is officially deprecated. This does not apply to anonymously defined typedef
classes/structs such as:
typedef struct {...} X;
2013-02-17: kwwette
When generating functions provided by %extend, use "(void)" for no-argument functions
instead of "()". This prevents warnings when compiling with "gcc -Wstrict-prototypes".
2013-02-17: kwwette
[Octave] Minor fix to autodoc generation: get the right type for functions returning structs.
2013-02-15: wsfulton
Deprecate typedef names used in %extend that are not the real class/struct name. For example:
typedef struct StructBName {
int myint;
} StructB;
%extend StructB {
void method() {}
}
will now trigger a warning:
swig_extend.i:19: Warning 326: Deprecated %extend name used - the struct name StructBName
should be used instead of the typedef name StructB.
This is only partially working anyway (the %extend only worked if placed after the class
definition).

Fix some feature matching issues for implicit destructors and implicit constructors and implicit
copy constructors added with %copyctor. Previously a feature for these had to be fully qualified
in order to match. Now the following will also match:
%feature("xyz") ~XXX();
struct XXX {};
2012-11-09: wsfulton
Further consistency in named output typemap lookups for implicit constructors and destructors and
implicit copy constructors added with %copyctor. Previously only the fully qualified name was being
used, now the unqualified name will also be used. For example, previously:
example.i:38: Searching for a suitable 'out' typemap for: void Space::More::~More
Looking for: void Space::More::~More
Looking for: void
Now the unqualified name is also used:
example.i:38: Searching for a suitable 'out' typemap for: void Space::More::~More
Looking for: void Space::More::~More
Looking for: void ~More
Looking for: void
2012-11-02: wsfulton
Fix some subtle named output typemap lookup misses, the fully qualified name was not always being
used for variables, for example:
struct Glob {

};
Previously the search rules (as shown by -debug-tmsearch) for the getter wrapper were:
example.i:44: Searching for a suitable 'out' typemap for: int MyVar
Looking for: int MyVar
Looking for: int
Now the scope is named correctly:
example.i:44: Searching for a suitable 'out' typemap for: int Glob::MyVar
Looking for: int Glob::MyVar
Looking for: int MyVar
Looking for: int
2012-10-26: wsfulton
Fix director typemap searching so that a typemap specified with a name will be correctly matched. Previously
the name was ignored during the typemap search. Applies to the following list of typemaps:
directorout, csdirectorout, cstype, imtype, ctype, ddirectorout, dtype, gotype, jtype, jni, javadirectorout.
2012-10-11: wsfulton
Most of the special variables available for use in %exception are now also available for expansion in
%extend blocks. These are: $name $symname $overname $decl $fulldecl $parentclassname $parentclasssymname, see docs
on "Class extension" in SWIGPlus.html. Patch based on submission from Kris Thielemans.
2012-10-10: wsfulton
Additional new special variables in %exception are expanded as follows:
$parentclassname - The parent class name (if any) for a method.
$parentclasssymname - The target language parent class name (if any) for a method.
2012-10-08: iant
[Go] Generating Go code now requires using the -intgosize option to

2012-09-14: wsfulton
Add new warning if the empty template instantiation is used as a base class, for example:
template <typename T> class Base {};
%template() Base<int>;

[Octave] Prevent Octave from seg-faulting at exit when SWIG
modules are loaded, due to bugs in Octave's cleanup code:
* Wrapping functions now declared with Octave DEFUN_DLD macro,
and loaded through Octave's dynamic module loader
* Global variables of swigref type are now assigned a new()
copy of the swigref class, to prevent double-free errors
* SWIG module at-exit cleanup function now created in Octave
through eval(), so not dependent on loaded .oct library
* For Octave versions 3.1.* to 3.3.*, register C-level at-exit
function which terminates Octave immediately (with correct
status code) without performing memory cleanup. This function
can be controlled with macros in Lib/octave/octruntime.swg
[Octave] New syntax for determing whether SWIG module should be
loaded globally or non-globally. To load module "example" globally,
type the module name
$ example;
as before; to load module non-globally, assign it to a variable:
$ example = example;
or
$ ex = example;
for a shorter (local) module name. -global/-noglobal command-line
options and module command line are deprecated. Added usage info
to module, so typing
$ help example
or incorrect usage should display proper usage, with examples.

2012-05-12: olly
[PHP] Avoid using zend_error_noreturn() as it doesn't work with all
builds of PHP (SF bug #3166423). Instead we now wrap it in a
SWIG_FAIL() function which we annotate as "noreturn" for GCC to
avoids warnings. This also reduces the size of the compiled

[Python] Add Python stepped slicing support to the STL wrappers (std::vector, std::list).
Assigning to a slice, reading a slice and deleting a slice with steps now work.
For example:

print list(vi)
vi[1:4:2] = [111, 333]
print list(vi)
del vi[3:10:3]
print list(vi)
print list(vi[::-1])
gives (same behaviour as native Python sequences such as list):
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
[0, 111, 2, 333, 4, 5, 6, 7, 8, 9]
[0, 111, 2, 4, 5, 7, 8]
[8, 7, 5, 4, 2, 111, 0]

[Python] Fix some indexing bugs in Python STL wrappers when the index is negative, eg:
%template(vector_i) std::vector<int>
iv=vector_i([0,1,2,3,4,5])
iv[-7:]
now returns [0, 1, 2, 3, 4, 5] instead of [5].
vv[7:9] = [22,33]
now returns [0, 1, 2, 3, 4, 5, 22, 33] instead of "index out range" error.
Also fix some segfaults when replacing ranges, eg when il is a std::list wrapper:
il[0:2] = [11]

[C#] Provide an easy way to override the default visibility for the proxy class pointer
constructors and getCPtr() method. The visibility is 'internal' by default and if multiple
SWIG modules are being used and compiled into different assemblies, then they need to be
'public' in order to use the constructor or getCPtr() method from a different assembly.
Use the following macros to change the visibilities in the proxy and type wrapper class:
SWIG_CSBODY_PROXY(public, public, SWIGTYPE)
SWIG_CSBODY_TYPEWRAPPER(public, public, public, SWIGTYPE)
[Java] Provide an easy way to override the default visibility for the proxy class pointer
constructors and getCPtr() method. The visibility is 'protected' by default and if multiple
SWIG modules are being used and compiled into different packages, then they need to be
'public' in order to use the constructor or getCPtr() method from a different package.
Use the following macros to change the visibilities in the proxy and type wrapper class:
SWIG_JAVABODY_PROXY(public, public, SWIGTYPE)
SWIG_JAVABODY_TYPEWRAPPER(public, public, public, SWIGTYPE)
The default for Java has changed from public to protected for the proxy classes. Use the

2011-07-26: wsfulton
Fix scoping of forward class declarations nested within a class (for C++). Previously the symbol
was incorrectly put into the outer namespace, eg
namespace std {
template<class Key, class T> struct map {
class iterator;
};
}
iterator was scoped as std::iterator, but now it is correctly std::map<Key, T>::iterator;
Also fixed is %template and template parameters that are a typedef when the template contains
default template parameters, eg:
namespace Std {
template<class Key, class T, class C = int> struct Map {
typedef Key key_type;
typedef T mapped_type;
};
}
typedef double DOUBLE;
%template(MM) Std::Map<int, DOUBLE>;
All symbols within Map will be resolved correctly, eg key_type and mapped_type no matter if the
wrapped code uses Std::Map<int, double> or std::Map<int, DOUBLE> or Std::Map<int, double, int>
Also fixes bug #3378145 - regression introduced in 2.0.4 - %template using traits.

the actual class.
- Fix default typemaps for C bindings, which were incorrectly attempting to
call non-existent destructors on user-defined types.
- New feature, feature:aclmixins, for adding superclass to the foreign class
wrappers.
- Improve longlong typemaps.
2011-06-19: wsfulton
Fix incorrect typemaps being used for a symbol within a templated type, eg:
A<int>::value_type would incorrectly use a typemap for type A.

[Tcl] Apply patch #3248280 from Christian Delbaere which adds better error messages when
the incorrect number or type of arguments are passed to overloaded methods.
2011-03-29: wsfulton
[Tcl] Apply patch #3224663 from Christian Delbaere.
1. Fix when function returns a NULL value, a "NULL" command will be created in the Tcl interpreter
and calling this command will cause a segmentation fault.
2. Previous implementation searches for class methods using a linear search causing performance issues
in wrappers for classes with many member functions. The patch adds a method hash table to classes and
changes method name lookup to use the hash table instead of doing a linear search.
2011-03-26: wsfulton
[C#, Java] SF bug #3195112 - fix wrapping of enums that are type char, for example:
enum { X = 'X'; }

[C#] Apply patch #3212624 fixing std::map Keys property.
2011-03-14: olly
[PHP] Fix handling of overloaded methods/functions where some

on the order they were encountered in (SF#3208299).
2011-03-13: klickverbot
[D] Extended support for C++ namespaces (nspace feature).
2011-03-12: olly

for a primitive type parameter in a method declaration.
2011-03-07: olly
[PHP] Don't use zend_error_noreturn() for cases where the function
returns void - now this issue can only matter if you have a function
or method which is directed and returns non-void.
2011-03-06: olly
[PHP] Add casts to the typemaps for long long and unsigned long
long to avoid issues when they are used with shorter types via
%apply.
2011-03-02: wsfulton
Templated smart pointers overloaded with both const and non const operator-> generated uncompilable
code when the pointee was a class with either public member variables or static methods.
Regression in 2.0.x reported as working in 1.3.40 by xantares on swig-user mailing list.
Version 2.0.2 (20 February 2011)
================================
2011-02-19: wsfulton
[PHP] Add missing INPUT, OUTPUT and INOUT typemaps in the typemaps.i library
for primitive reference types as well as signed char * and bool *.
2011-02-19: olly
[PHP] Address bug in PHP on some platforms/architectures which
results in zend_error_noreturn() not being available using
SWIG_ZEND_ERROR_NORETURN which defaults to zend_error_noreturn but
can be overridden when building the module by passing
-DSWIG_ZEND_ERROR_NORETURN=zend_error to the compiler. This may
result in compiler warnings, but should at least allow a module
to be built on those platforms/architectures (SF#3166423).
2011-02-18: wsfulton
Fix #3184549 - vararg functions and function overloading when using the -fastdispatch option.
2011-02-18: olly

2011-02-13: wsfulton
Fix #1927852 - #include directives don't preprocess the file passed to it. The fix is for
#include with -importall or -includeall, %include and %import, for example:
#define FILENAME "abc.h"
%include FILENAME
2011-02-12: wsfulton
Fix #1940536, overactive preprocessor which was expanding defined(...) outside of #if and #elif
preprocessor directives.
2011-02-05: wsfulton

2011-02-01: wsfulton
[C#] Directors - a call to a method being defined in the base class, not
overridden in a subclass, but again overridden in a class derived from
the first subclass was not being dispatched correctly to the most derived class.
See director_alternating.i for an example.
2011-02-01: wsfulton
[C#, Java] Any 'using' statements in the protected section of a class were previously
ignored with director protected (dirprot) mode.
2011-01-30: wsfulton
Fix overloading with const pointer reference (SWIGTYPE *const&) parameters for a
number of scripting languages.
2011-01-17: wsfulton
New warning for smart pointers if only some of the classes in the inheritance
chain are marked as smart pointer, eg, %shared_ptr should be used for all classes
in an inheritance hierarchy, so this new warning highlights code where this is
not the case.
example.i:12: Warning 520: Base class 'A' of 'B' is not similarly marked as a smart pointer.
example.i:16: Warning 520: Derived class 'C' of 'B' is not similarly marked as a smart pointer.
2011-01-14: wsfulton
Added some missing multi-argument typemaps: (char *STRING, size_t LENGTH) and
(char *STRING, int LENGTH). Documentation for this updated. Java patch from
Volker Grabsch.
2011-01-11: iant
Require Go version 7077 or later.
2010-12-30: klickverbot
[C#, D, Java] Check for collision of parameter names with target
language keywords when generating the director glue code.
The situation in which the generated could would previously be
invalid is illustrated in the new 'director_keywords' test case.
2010-12-23: wsfulton
[C#] Fix $csinput special variable not being expanded for csvarin typemaps
when used for global variables. Reported by Vadim Zeitlin.
2010-12-14: wsfulton
Fix $basemangle expansion in array typemaps. For example if type is int *[3],
$basemangle expands to _p_int.
2010-12-07: iant
Check that we are using a sufficiently new version of the
6g or 8g Go compiler during configure time. If not, disable Go.

*** POTENTIAL INCOMPATIBILITY ***
2010-12-06: wsfulton
Fix #3127394 - use of network paths on Windows/MSys.
2010-11-18: klickverbot
[D] Added the D language module.
2010-11-12: vadz
Fix handling of multiple regex-using %renames attached to the same
declaration. For example, now
%rename("%(regex:/^Set(.*)/put\\1/)s") "";
%rename("%(regex:/^Get(.*)/get\\1/)s") "";
works as expected whereas before only the last anonymous rename was
taken into account.
2010-10-17: drjoe
[R] Fix failure in overloaded functions which was breaking
QuantLib-SWIG
2010-10-14: olly
[PHP] Allow compilation on non-conforming Microsoft C++ compilers
which don't accept: return function_returning_void();
Reported by Frank Vanden Berghen on the SWIG mailing list.
2010-10-12: wsfulton
Fix unary scope operator (::) (global scope) regression introduced in 2.0.0, reported by
Ben Walker. The mangled symbol names were incorrect, sometimes resulting in types being
incorrectly treated as opaque types.
Also fixes #2958781 and some other type problems due to better typedef resolution, eg
std::vector<T *>::value_type didn't resolve to T * when it should have. The mangled type
was incorrectly SWIGTYPE_std__vectorT_Test_p_std__allocatorT_Test_p_t_t__value_type and now
it is correctly SWIGTYPE_p_Test.
Version 2.0.1 (4 October 2010)
==============================
2010-10-03: wsfulton
Apply patch #3066958 from Mikael Johansson to fix default smart pointer
handling when the smart pointer contains both a const and non-const operator->.

named namespace.
2010-09-24: wsfulton
More file and line error/warning reporting fixes where SWIG macros
are used within {} braces (where the preprocessor expands macros),
for example macros within %inline {...} and %fragment(...) {...}
and nested structs.
2010-09-18: wsfulton
More file and line error/warning reporting fixes for various inherited
class problems.
2010-09-15: wsfulton
A much improved debugging of SWIG source experience is now available and
documented in the "Debugging SWIG" section in the Doc/Devel/internals.html
file, including a swig.dbg support file for the gdb debugger.
2010-09-11: wsfulton
Fix incorrect line number reporting in errors/warnings when a macro
definition ends with '/' and it is not the end of a C comment.
2010-09-11: wsfulton
Fix incorrect line number reporting in errors/warnings after parsing
macro invocations with parameters given over more than one line.
2010-09-10: wsfulton
Remove extraneous extra line in preprocessed output after including files

end of the file.
2010-09-10: wsfulton
Fix #2149523 - Incorrect line number reporting in errors after parsing macros
containing C++ comments.
2010-09-08: olly
[PHP] Fix handling of OUTPUT typemaps (Patch from Ryan in SF#3058394).
2010-09-03: wsfulton
Fix erroneous line numbers in error messages for macro expansions, for example,
the error message now points to instantiation of the macro, ie the last line here:
#define MACRO2(a, b)
#define MACRO1(NAME) MACRO2(NAME,2,3)
MACRO1(abc)
2010-09-02: wsfulton
Fix line numbers in error and warning messages for preprocessor messages within
%inline, for example:
%inline %{
#define FOOBAR 1
#define FOOBAR "hi"
%}
2010-09-02: wsfulton
Fix line numbers in error and warning messages which were cumulatively one
less than they should have been after parsing each %include/%import - bug
introduced in swig-1.3.32. Also fix line numbers in error and warning messages
when new line characters appear between the %include / %import statement and
the filename.
2010-08-30: wsfulton
Fix line number and file name reporting for some macro preprocessor warnings.
The line number of the macro argument has been corrected and the line number
of the start of the macro instead of one past the end of the macro is used.
Some examples:
file.h:11: Error: Illegal macro argument name '..'
file.h:19: Error: Macro 'DUPLICATE' redefined,
file.h:15: Error: previous definition of 'DUPLICATE'.
file.h:25: Error: Variable-length macro argument must be last parameter
file.h:32: Error: Illegal character in macro argument name
file.i:37: Error: Macro 'SIT' expects 2 arguments
2010-08-26: wsfulton

set before calling strtod - patch from Justin Vallon - SF Bug #3038936.
2010-08-17: wsfulton
Fix make distclean when some of the more obscure languages are detected by
configure - fixes from Torsten Landschoff.
2010-07-28: wsfulton
Restore configuring out of source for the test-suite since it broke in 1.3.37.
As previously, if running 'make check-test-suite' out of source, it needs to be
done by invoking configure with a relative path. Invoking configure with an
absolute path will not work. Running the full 'make check' still needs to be
done in the source tree.
2010-07-16: wsfulton
Fix wrapping of function pointers and member function pointers when the function
returns by reference.
2010-07-13: vadz
Removed support for the old experimental "rxspencer" encoder and
"[not]rxsmatch" in %rename (see the 01/16/2006 entry). The new and
officially supported "regex" encoder and "[not]regexmatch" checks
should be used instead (see the two previous entries). Please
replace "%(rxspencer:[pat][subst])s" with "%(regex:/pat/subst/)s"
when upgrading. Notice that you will also need to replace the back-
references of form "@1" with the more standard "\\1" and may need to
adjust your regular expressions syntax as the new regex encoder uses
Perl-compatible syntax and not (extended) POSIX syntax as the old one.
*** POTENTIAL INCOMPATIBILITY ***
2010-07-13: vadz
Add "regexmatch", "regextarget" and "notregexmatch" which can be
used to apply %rename directives to the declarations matching the
specified regular expression only. The first two can be used
interchangeably, both of the %renames below do the same thing:
%rename("$ignore", regexmatch$name="Old$") "";
%rename("$ignore", regextarget=1) "Old$";
(namely ignore the declarations having "Old" suffix).
"notregexmatch" restricts the match to only the declarations which
do not match the regular expression, e.g. here is how to rename to
lower case versions all declarations except those consisting from
capital letters only:
%rename("$(lowercase)s", notregexmatch$name="^[A-Z]+$") "";
2010-07-13: vadz
Add the new "regex" encoder that can be used in %rename, e.g.
%rename("regex:/(\\w+)_(.*)/\\2/") "";
to remove any alphabetical prefix from all identifiers. The syntax
of the regular expressions is Perl-like and PCRE library
(http://www.pcre.org/) is used to implement this feature but notice
that backslashes need to be escaped as usual inside C strings.
Original patch from Torsten Landschoff.
2010-07-08: wsfulton
Fix #3024875 - shared_ptr of classes with non-public destructors. This also fixes
the "unref" feature when used on classes with non-public destructors.
2010-06-17: ianlancetaylor
[Go] Add the Go language module.
2010-06-10: wsfulton
[Lua] Fix SWIG_lua_isnilstring multiply defined when using multiple

2010-06-10: olly
[PHP] Fix directors to correctly call a method with has a
different name in PHP to C++ (we were always using the C++ name
in this case).
2010-06-03: wsfulton
Fix uncompilable code when %rename results in two enum items
with the same name. Reported by Vadim Zeitlin.
Version 2.0.0 (2 June 2010)
===========================
2010-06-02: wsfulton
[C#] Fix SWIG_STD_VECTOR_ENHANCED macro used in std::vector to work with
types containing commas, for example:
SWIG_STD_VECTOR_ENHANCED(std::pair< double, std::string >)
2010-06-01: wsfulton
Add in std_shared_ptr.i for wrapping std::shared_ptr. Requires the %shared_ptr
macro like in the boost_shared_ptr.i library. std::tr1::shared_ptr can also be
wrapped if the following macro is defined:
#define SWIG_SHARED_PTR_SUBNAMESPACE tr1
%include <std_shared_ptr.i>
shared_ptr is also documented in Library.html now.
2010-05-27: wsfulton
Add the ability for $typemap special variable macros to call other $typemap
special variable macros, for example:
%typemap(cstype) CC "CC"
%typemap(cstype) BB "$typemap(cstype, CC)"
%typemap(cstype) AA "$typemap(cstype, BB)"
void hah(AA aa);
This also fixes C# std::vector containers of shared_ptr and %shared_ptr.
Also added diagnostics for $typemap with -debug-tmsearch, for example, the
above displays additional diagnostic lines starting "Containing: ":
example.i:34: Searching for a suitable 'cstype' typemap for: AA aa
Looking for: AA aa
Looking for: AA
Using: %typemap(cstype) AA
Containing: $typemap(cstype, BB)
example.i:31: Searching for a suitable 'cstype' typemap for: BB
Looking for: BB
Using: %typemap(cstype) BB
Containing: $typemap(cstype, CC)
example.i:29: Searching for a suitable 'cstype' typemap for: CC
Looking for: CC
Using: %typemap(cstype) CC
2010-05-26: olly
Fix %attribute2ref not to produce a syntax error if the last
argument (AccessorMethod) is omitted. Patch from David Piepgras
in SF#2235756.
2010-05-26: olly
[PHP] When using %throws or %catches, SWIG-generated PHP5 wrappers
now throw PHP Exception objects instead of giving a PHP error of
type E_ERROR.
This change shouldn't cause incompatibility issues, since you can't
set an error handler for E_ERROR, so previously PHP would just exit
which also happens for unhandled exceptions. The benefit is you can
now catch them if you want to.
Fixes SF#2545578 and SF#2955522.
2010-05-25: olly
[PHP] Add missing directorin typemap for const std::string &.

[C#] Fix #2957375 - SWIGStringHelper and SWIGExceptionHelper not always being
initialized before use in .NET 4 as the classes were not marked beforefieldinit.
A static constructor has been added to the intermediary class like this:
%pragma(csharp) imclasscode=%{
static $imclassname() {
}
%}
If you had added your own custom static constructor to the intermediary class in
the same way as above, you will have to modify your approach to use static variable
initialization or define SWIG_CSHARP_NO_IMCLASS_STATIC_CONSTRUCTOR - See csharphead.swg.

Fix #2408232. Improve shared_ptr and intrusive_ptr wrappers for classes in an
inheritance hierarchy. No special treatment is needed for derived classes.
The proxy class also no longer needs to be specified, it is automatically
deduced. The following macros are deprecated:
SWIG_SHARED_PTR(PROXYCLASS, TYPE)
SWIG_SHARED_PTR_DERIVED(PROXYCLASS, BASECLASSTYPE, TYPE)
and have been replaced by
%shared_ptr(TYPE)
Similarly for intrusive_ptr wrappers, the following macro is deprecated:
SWIG_INTRUSIVE_PTR(PROXYCLASS, TYPE)
SWIG_INTRUSIVE_PTR_DERIVED(PROXYCLASS, BASECLASSTYPE, TYPE)
and have been replaced by
%intrusive_ptr(TYPE)

Numerous subtle typemap matching rule fixes when using the default type. The typemap
matching rules are to take a type and find the best default typemap (SWIGTYPE, SWIGTYPE* etc),
then look for the next best match by reducing the chosen default type. The type deduction
now follows C++ class template partial specialization matching rules.
Below are the set of changes made showing the default type deduction
along with the old reduced type and the new version of the reduced type:
SWIGTYPE const &[ANY]
new: SWIGTYPE const &[]
old: SWIGTYPE (&)[ANY]
SWIGTYPE *const [ANY]
new: SWIGTYPE const [ANY]
old: SWIGTYPE *[ANY]
SWIGTYPE const *const [ANY]
new: SWIGTYPE *const [ANY]
old: SWIGTYPE const *[ANY]
SWIGTYPE const *const &
new: SWIGTYPE *const &
old: SWIGTYPE const *&
SWIGTYPE *const *
new: SWIGTYPE const *
old: SWIGTYPE **
SWIGTYPE *const &
new: SWIGTYPE const &
old: SWIGTYPE *&
Additionally, a const SWIGTYPE lookup is used now for any constant type. Some examples, where
T is some reduced type, eg int, struct Foo:
T const
new: SWIGTYPE const
old: SWIGTYPE
T *const
new: SWIGTYPE *const
old: SWIGTYPE *
T const[]
new: SWIGTYPE const[]
old: SWIGTYPE[]
enum T const
new: enum SWIGTYPE const
old: enum SWIGTYPE
T (*const )[]
new: SWIGTYPE (*const )[]
old: SWIGTYPE (*)[]
Reminder: the typemap matching rules can now be seen for any types being wrapped by using
either the -debug-tmsearch or -debug-tmused options.
In practice this leads to some subtle matching rule changes and the majority of users
won't notice any changes, except in the prime area of motivation for this change: Improve
STL containers of const pointers and passing const pointers by reference. This is fixed
because many of the STL containers use a type 'T const&' as parameters and when T is
a const pointer, for example, 'K const*', then the full type is 'K const*const&'. This
means that the 'SWIGTYPE *const&' typemaps now match when T is either a non-const or
const pointer. Furthermore, some target languages incorrectly had 'SWIGTYPE *&' typemaps
when these should have been 'SWIGTYPE *const&'. These have been corrected (Java, C#, Lua, PHP).

[Java] The intermediary JNI class modifiers are now public by default meaning these

2010-03-06: wsfulton
[C#] Added the nspace feature for C#. Documentation for the nspace feature is now available.
2010-03-04: wsfulton
Added the nspace feature. This adds some improved namespace support. Currently only Java
is supported for target languages, where C++ namespaces are automatically translated into
Java packages. The feature only applies to classes,struct,unions and enums declared within
a namespace. Methods and variables declared in namespaces still effectively have their
namespaces flattened. Example usage:
%feature(nspace) Outer::Inner1::Color;
%feature(nspace) Outer::Inner2::Color;
namespace Outer {
namespace Inner1 {
struct Color {
...
};
}
namespace Inner2 {
struct Color {
...
};
}
}
For Java, the -package option is also required when using the nspace feature. Say
we use -package com.myco, the two classes can then be accessed as follows from Java:
com.myco.Outer.Inner1.Color and com.myco.Outer.Inner2.Color.

Replace SWIGWARN_PARSE_NESTED_CLASS with SWIGWARN_PARSE_NAMED_NESTED_CLASS and

Named nested class ignored warnings can now be suppressed by name using %warnfilter, eg:
%warnfilter(SWIGWARN_PARSE_NAMED_NESTED_CLASS) Outer::Inner;
but clearly unnamed nested classes cannot and the global suppression is still required, eg:
#pragma SWIG nowarn=SWIGWARN_PARSE_UNNAMED_NESTED_CLASS
2009-11-11: wsfulton
Added the nestedworkaround feature as a way to use the full functionality of a nested class
(C++ mode only). It removes the nested class from SWIG's type information so it is as if SWIG
had never parsed the nested class. The documented nested class workarounds using a global
fake class stopped working when SWIG treated the nested class as an opaque pointer, and
this feature reverts this behaviour. The documentation has been updated with details of how
to use and implement it, see the "Nested classes" section in SWIGPlus.html.
2009-11-11: wsfulton
There were a number of C++ cases where nested classes/structs/unions were being handled
as if C code was being parsed which would oftentimes lead to uncompilable code as an
attempt was made to wrap the nested structs like it is documented for C code. Now all
nested structs/classes/unions are ignored in C++ mode, as was always documented. However,
there is an improvement as usage of nested structs/classes/unions is now always treated
as an opaque type by default, resulting in generated code that should always compile.

struct InnerStruct { int x; };

template<typename T> class X<T *> {};
%template(X1) X<const int *>; // Chooses T * specialization
and more complex cases with multiple parameters and a mix of template argument
deduction and explicitly specialised parameters, eg:
template <typename T1, typename T2> struct TwoParm { void a() {} };
template <typename T1> struct TwoParm<T1 *, int *> { void e() {} };
%template(E) TwoParm<int **, int *>;

[Perl] Don't specify Perl prototype "()" for a constructor with a
different name to the class, as such constructors can still take
parameters.
2009-07-12: xavier98
[Octave] Add support for Octave 3.2 API
2009-07-05: olly
[PHP] Update the list of PHP keywords - "cfunction" is no longer a
keyword in PHP5 and PHP 5.3 added "goto", "namespace", "__DIR__",
and "__NAMESPACE__".
2009-07-03: olly
[Tcl] To complement USE_TCL_STUBS, add support for USE_TK_STUBS
and SWIG_TCL_STUBS_VERSION. Document all three in the Tcl chapter
of the manual. Based on patch from SF#2810380 by Christian
Gollwitzer.
2009-07-02: vmiklos
[PHP] Added factory.i for PHP, see the li_factory testcase
for more info on how to use it.
2009-07-02: wsfulton
Fix -Wallkw option as reported by Solomon Gibbs.
2009-07-02: wsfulton
Fix syntax error when a nested struct contains a comment containing a * followed
eventually by a /. Regression from 1.3.37, reported by Solomon Gibbs.
2009-07-01: vmiklos
[PHP] Unknown properties are no longer ignored in proxy
classes.
2009-07-01: vmiklos
[PHP] Fixed %newobject behaviour, previously any method
marked with %newobject was handled as a constructor.
2009-06-30: olly
[Ruby] Undefine close and connect macros defined by Ruby API
headers as we don't need them and they can clash with C++ methods
being wrapped. Patch from Vit Ondruch in SF#2814430.
2009-06-26: olly
[Ruby] Fix to handle FIXNUM values greater than MAXINT passed for a
double parameter.
2009-06-24: wsfulton
Fix wrapping methods with default arguments and the compactdefaultargs feature
where a class is passed by value and is assigned a default value. The SwigValueWrapper
template workaround for a missing default constructor is no longer used as the code
generated does not call the default constructor.
2009-06-16: wsfulton
[Java,C#] Fix enum marshalling when %ignore is used on one of the enum items.
Incorrect enum values were being passed to the C++ layer or compilation errors resulted.

[Perl] Resolved reference.i overload support problem
identified by John Potowsky.
2009-05-26: wsfulton
[C#] Improved std::map wrappers based on patch from Yuval Baror. The C# proxy
now implements System.Collections.Generic.IDictionary<>.
These std:map wrappers have a non-backwards compatible overhaul to make them
like a .NET IDictionary. Some method names have changed as following:
set -> setitem (use this[] property now)
get -> getitem (use this[] property now)
has_key -> ContainsKey
del -> Remove
clear -> Clear
The following macros used for std::map wrappers are deprecated and will no longer work:
specialize_std_map_on_key
specialize_std_map_on_value
specialize_std_map_on_both

2009-05-20: vmiklos
[PHP] Add the 'thisown' member to classes. The usage of it
is the same as the Python thisown one: it's 1 by default and
you can set it to 0 if you want to prevent freeing it. (For
example to prevent a double free.)
2009-05-14: bhy
[Python] Fix the wrong pointer value returned by SwigPyObject_repr().

[C#] Improved std::vector wrappers on the C# proxy side from Yuval Baror. These
implement IList<> instead of IEnumerable<> where possible.
2009-04-29: wsfulton
[Java, C#] Add the 'notderived' attribute to the javabase and csbase typemaps.
When this attribute is set, the typemap will not apply to classes that are derived
from a C++ base class, eg
%typemap(csbase, notderived="1") SWIGTYPE "CommonBase"
2009-04-29: olly
[Python] Don't attempt to acquire the GIL in situations where we
know that it will already be locked. This avoids some dead-locks
with mod_python (due to mod_python bugs which are apparently
unlikely to ever be fixed), and results in smaller wrappers which
run a little faster (in tests with Xapian on x86-64 Ubuntu 9.04,
the stripped wrapper library was 11% smaller and ran 2.7% faster).

Fix #2746858 - C macro expression using floating point numbers
2009-03-30: olly
[PHP] The default out typemap for char[ANY] now returns the string up to a
zero byte, or the end of the array if there is no zero byte. This
is the same as Python does, and seems more generally useful than
the previous behaviour of returning the whole contents of the array
including any zero bytes. If you want the old behaviour, you can provide
your own typemap to do this:
%typemap(out) char [ANY]
%{
RETVAL_STRINGL($1, $1_dim0, 1);
%}

[Python] Fix the memory leak related to Python 3 unicode and C char* conversion,
which can be shown in the following example before this fix:
from li_cstring import *
i=0
while True:
i += 1
n = str(i)*10
test3(n)
This fix affected SWIG_AsCharPtrAndSize() so you cannot call this function with
a null alloc and non-null cptr argument in Python 3, otherwise a runtime error
will be raised.
2009-03-18: wsfulton
[C#] std::vector<T> wrapper improvements for .NET 2 and also providing the
necessary machinery to use the std::vector<T> wrappers with more advanced features such
as LINQ - the C# proxy class now derives from IEnumerable<>. The default is now to
generate code requiring .NET 2 as a minimum, although the C# code can be compiled
for .NET 1 by defining the SWIG_DOTNET_1 C# preprocessor constant. See the
std_vector.i file for more details.

[Python] Some fixes for Python 3.0.1 and higher support. In 3.0.1, the C API function
PyObject_Compare is removed, so PyObject_RichCompareBool is used for replacement.
Struct initilization of SwigPyObject and SwigPyObject_as_number changed to reflect
the drop of tp_compare and nb_long.

New %insert("begin") section added. Also can be used as %begin. This is a new
code section reserved entirely for users and the code within the section is generated
at the top of the C/C++ wrapper file and so provides a means to put custom code
into the wrapper file before anything else that SWIG generates.
2009-02-17: wsfulton
'make clean-test-suite' will now run clean on ALL languages. Previously it only
ran the correctly configured languages. This way it is now possible to clean up

Extend attribute library support for structs/classes and the accessor functions use
pass/return by value semantics. Two new macros are available and usage is identical
to %attribute. These are %attributeval for structs/classes and %attributestring for
string classes, like std::string. See attribute.swg for more details.
2009-02-13: wsfulton
Add support for %extend and memberin typemaps. Previously the memberin typemaps were

Remove unnecessary temporary variable when wrapping return values that are references.
Example of generated code for wrapping:

[Python] Applied patch SF#2158938: all the SWIG symbol names started with Py
are changed, since they are inappropriate and discouraged in Python
documentation (from http://www.python.org/doc/2.5.2/api/includes.html):
"All user visible names defined by Python.h (except those defined by
the included standard headers) have one of the prefixes "Py" or "_Py".
Names beginning with "_Py" are for internal use by the Python implementation
and should not be used by extension writers. Structure member names do
not have a reserved prefix.
Important: user code should never define names that begin with "Py" or "_Py".
This confuses the reader, and jeopardizes the portability of the user
code to future Python versions, which may define additional names beginning
with one of these prefixes."
Here is a brief list of what changed:
PySwig* -> SwigPy*
PyObject_ptr -> SwigPtr_PyObject
PyObject_var -> SwigVar_PyObject
PySequence_Base, PySequence_Cont, PySequence_Ref ->
SwigPySequence_Base, SwigPySequence_Cont, SwigPySequence_Ref
PyMap* -> SwigPyMap*
We provided a pyname_compat.i for backward compatibility. Users whose code having
these symbols and do not want to change it could simply include this file
at front of your code. A better solution is to run the converting tool on
your code, which has been put in SWIG's SVN trunk (Tools/pyname_patch.py) and
you can download it here:
https://swig.svn.sourceforge.net/svnroot/swig/trunk/Tools/pyname_patch.py

[Python] Apply patch #2143727 from Serge Monkewitz to fix importing base classes

2008-11-28: wsfulton
[UTL] Fix #2080497. Some incorrect acceptance of types in the STL, eg a double * element
passed into a vector<int *> constructor would be accepted, but the ensuing behaviour
was undefined. Now the type conversion correctly raises an exception.
2008-11-24: wsfulton
Add -outcurrentdir option. This sets the default output directory to the current
directory instead of the path specified by the input file. This option enables
behaviour similar to c/c++ compilers. Note that this controls the output directory,
but only in the absence of the -o and/or -outdir options.

2008-11-16: wsfulton
Fix -nopreprocess option to:
- correctly report file names in warning and error messages.
- use the original input filename that created the preprocessed output when
determining the C++ wrapper file name (in the absence of -o). Previously
the name of the input file containing the preprocessed output was used.

Add patch #2128249 from Anatoly Techtonik which corrects the C/C++ proxy
class being reported for Python docstrings when %rename is used.
2008-11-01: wsfulton
Add the strip encoder patch from Anatoly Techtonik #2130016. This enables an
easy way to rename symbols by stripping a commonly used prefix in all the
function/struct names. It works in the same way as the other encoders, such as
title, lower, command etc outlined in CHANGES file dated 12/30/2005. Example
below will rename wxAnotherWidget to AnotherWidget and wxDoSomething to
DoSomething:
%rename("%(strip:[wx])s") "";

Document the optional module attribute in the %import directive,
see Modules.html. Add a warning for Python wrappers when the
module name for an imported base class is missing, requiring the

%import(module="FooModule") foo.h
2008-09-18: olly
[PHP5] Change the default input typemap for char * to turn PHP
Null into C NULL (previously it was converted to an empty string).
The new behaviour is consistent with how the corresponding output
typemap works (SF#2025719).
If you want to keep the old behaviour, add the following typemap
to your interface file (PHP's convert_to_string_ex() function does
the converting from PHP Null to an empty string):
%typemap(in) char * {
convert_to_string_ex($input);
$1 = Z_STRVAL_PP($input);

[allegrocl]
- Fix how forward reference typedefs are handled, so as not to conflict
with other legit typedefs.
- Don't (for now) perform an ffitype typemap lookup when trying to
when calling compose_foreign_type(). This is actually a useful thing
to do in certain cases, the test cases for which I can't currently
locate :/. It's breaking some wrapping behavior that is more commonly
seen, however. I'll readd in a more appropriate way when I can
recreate the needed test case, or a user complains (which means
they probably have a test case).
- document the -isolate command-line arg in the 'swig -help' output.
It was in the html docs, but not there.
- small amount of code cleanup, removed some unused code.
- some minor aesthetic changes.

[Python] Python 3.0 support branch merged into SWIG trunk. Thanks to
Google Summer of Code 2008 for supporting this project! By default
SWIG will generate interface files compatible with both Python 2.x
and 3.0. And there's also some Python 3 new features that can be
enabled by passing a "-py3" command line option to SWIG. These
features are:
- Function annotation support
Also, the parameter list of proxy function will be generated,
even without the "-py3" option. However, the parameter list
will fallback to *args if the function (or method) is overloaded.
- Buffer interface support
- Abstract base class support
For details of Python 3 support and these features, please see the
"Python 3 Support" section in the "SWIG and Python" chapter of the SWIG
documentation.
The "-apply" command line option and support of generating codes
using apply() is removed. Since this is only required by very old
Python.
This merge also patched SWIG's parser to solve a bug. By this patch,
SWIG features able to be correctly applied on C++ conversion operator,
such like this:
%feature("shadow") *::operator bool %{ ... %}

New partialcheck makefile targets for partial testing of the test-suite. These
just invoke SWIG, ie no compilation and no runtime testing. It can be faster
when developing by just doing a directory diff of the files SWIG generates
against those from a previous run. Example usage from the top level directory:
make partialcheck-test-suite
make partialcheck-java-test-suite
This change also encompasses more flexibility in running the test-suite, eg
it is possible to prefix the command line which runs any target language test
with a tool. See the RUNTOOL, COMPILETOOL and SWIGTOOL targets in the common.mk
file and makefiles in the test-suite directory. For example it is possible to
run the runtime tests through valgrind using:
make check RUNTOOL="valgrind --leak-check=full"
or invoke SWIG under valgrind using:
make check SWIGTOOL="valgrind --tool=memcheck"

Ran 'astyle --style=kr -2' across lua.cxx to neaten it up
02/10/2008: wsfulton
Bump SWIG_RUNTIME_VERSION to 4. This is because of the recently introduced API
change in the conversion functions, ie change in definition of swig_converter_func.
Anyone calling SWIG_TypeCast must pass in a valid value for the new additional
(third) parameter and then handle the newly created memory if the returned value
is set to SWIG_CAST_NEW_MEMORY else a memory leak will ensue.
02/09/2008: wsfulton
[Python] Experimental shared_ptr typemaps added. Usage is the same as the recently
added Java and C# shared_ptr typemaps. Two macros are available, although these
may well change in a future version:
For base classes or classes not in an inheritance chain:
SWIG_SHARED_PTR(PROXYCLASS, TYPE)
For derived classes:
SWIG_SHARED_PTR_DERIVED(PROXYCLASS, BASECLASSTYPE, TYPE)
The PROXYCLASS is the name of the proxy class, but is only required for Java/C#.
Example usage:
%include "boost_shared_ptr.i"
SWIG_SHARED_PTR(Klass, Space::Klass)
SWIG_SHARED_PTR_DERIVED(KlassDerived, Space::Klass, Space::KlassDerived)
namespace Space {
struct Klass { ... };
struct KlassDerived : Klass { ... };
}
Further details to follow in future documentation, but the following features
should be noted:
- Not restricted to boost::shared_ptr, eg std::tr1::shared_ptr can also be used.
- Available typemap groups:
(a) Typemaps for shared_ptr passed by value, reference, pointer and pointer
reference.
- (b) Typemaps for passing by raw value, raw pointer, raw reference, raw pointer
reference.
- The code being wrapped does not even have to use shared_ptr, SWIG can use
shared_ptr as the underlying storage mechanism instead of a raw pointer due to
the typemaps in group (b) above.
- No array support as shared_ptr does not support arrays.
- This works quite differently to the usual SWIG smart pointer support when
operator-> is parsed by SWIG:
- An additional smart pointer class is not generated reducing code bloat in
the wrappers.
- Using smart pointers and raw pointers can be mixed seamlessly.
- Missing constructors for the smart pointers is no longer a problem and so
separate factory type functions do not have to be written and wrapped.
- The implicit C++ shared_ptr< derived class > to shared_ptr< base class >
cast also works in the target language. This negates the necessity to write
an explicit helper cast function providing the upcast which would need
calling prior to passing a derived class to a method taking a shared_ptr to
a base class.
02/09/2008: wsfulton
[Python] Add support for overriding the class registration function via a new
"smartptr" feature. This is a very low level of customisation most users
would never need to know. The feature will typically be used for intrusive
smart pointers along with additional typemaps. Example usage of the feature:
%feature("smartptr", noblock=1) Foo { boost::shared_ptr< Foo > }
class Foo {};
The generated Foo_swigregister function will then register boost::shared < Foo >
(SWIGTYPE_p_boost__shared_ptrTFoo_t instead of SWIGTYPE_p_Foo) as the underlying
type for instantiations of Foo.
02/09/2008: wsfulton
Features now supports the optional 'noblock' attribute for all usage of %feature.
When specified, the { } braces are removed from the feature code. This is identical
in behaviour to usage of 'noblock' in typemaps and is used when the preprocessor
is required to operate on the code in the feature and the enclosing { } braces
are not required. Example:
#define FOO foo
%feature("smartptr", noblock="1") { FOO::bar }
The preprocessor then reduces this as if this had been used instead:
%feature("smartptr") "foo::bar"
02/01/2008: olly
[Python] Fix format string bug (SF#1882220).
01/31/2008: wsfulton
Additions to the %types directive. Now the conversion / casting code can be
overridden to some custom code in the %types directive, like so:
%types(fromtype = totype) %{
... code to convert fromtype to totype and return ...
%}
The special variable $from will be replaced by the name of the parameter of the
type being converted from. The code must return the totype cast to void *. Example:
class Time;
class Date;
Date &Time::dateFromTime();
%types(Time = Date) %{
Time *t = (Time *)$from;
Date &d = t->dateFromTime();
return (void *) &d;
%}
resulting in the conversion / casting code looking something like:
static void *_p_TimeTo_p_Date(void *x) {
Time *t = (Time *)x;
Date &d = t->dateFromTime();
return (void *) &d;
}
This is advanced usage, please use only if you understand the runtime type system.

Also changed typemaps.i not to check for NULL before freeing a pointer
01/21/2008: wsfulton
[Python] For STL containers, SWIG no longer attempts to convert from one
STL container to another, eg from std::vector<int> to std::vector<double>
or std::list<int> to std::vector<int> or even std::vector<Foo> to
std::vector<Bar> as it previously did. In fact SWIG no longer attempts to
convert any SWIG wrapped C++ proxy class that is also a Python sequence,
whereas previously it would. Any non-SWIG Python sequence will still be
accepted wherever an STL container is accepted. Overloaded methods using
containers should be faster.
01/18/2008: wsfulton
[C#] Add 'directorinattributes' and 'directoroutattributes' typemap attributes

11/10/2007: olly
[php] Fix makefile generated by -make (SF#1633679). Update
documentation to mark "-make" as deprecated (none of the other
SWIG backends seem to offer such a feature, it can't realistically
generate a fully portable makefile, and the commands to build an

tool). Also recommend against the use of "-phpfull" (it's only
really useful when static linking, and a dynamically loadable

[Java] Add DetachCurrentThread back in for directors. See entry dated 08/11/2006 and
search for DetachCurrentThread on the mailing lists for details. The crashes on Solaris
seem to be only present in jdk-1.4.2 and lower (jdk-1.5.0 and jdk-1.6.0 are okay), so
anyone using directors should use a recent jdk on Solaris, or define (see director.swg)
SWIG_JAVA_NO_DETACH_CURRENT_THREAD to the C++ compiler to get old behaviour.

- Change r_ltype in typesys.c to store a hashtable instead of a single value.
several very subtle bugs were being caused by multiple ltypes being mapped
to a single mangled type, mostly when using typedefed template parameters.
Now, r_ltype stores a hashtable of possible ltypes, and when generating the
type table, all the ltypes are added into the swig_type_info structure.

SF #1754967 from James Bigler.
- Fix bug in turning on warnings that were turned off by default. Eg 'swig -w+309' will now
turn on the normally suppressed warning 309.
- New -Wextra commandline option which enables the extra warning numbers:
202,309,403,512,321,322 (this is the list of warnings that have always been suppressed by
default). By specifying -Wextra, all warnings will be turned on, but unlike -Wall,
warnings can still be selectively turned on/off using %warnfilter,
#pragma SWIG nowarn or further -w commandline options, eg:
swig -Wextra -w309
will turn on all warnings except 309.
08/28/2007: wsfulton
- New debugging options, -debug-module <n> and -debug-top <n> to display the parse tree at

swig -debug-top 1,3

-dump_parse_module => -debug-module 1
-dump_module => -debug-module 4
-dump_parse_top => -debug-top 1
-dump_top => -debug-top 4
- Renamed some commandline options for naming consistency across all options:
-debug_template => -debug-template
-debug_typemap => -debug-typemap
-dump_classes => -debug-classes
-dump_tags => -debug-tags
-dump_typedef => -debug-typedef

Fixed %rename inconsistency in conversion operators as reported by Zhong Ren. The matching

%rename(opABC) Space::ABC::operator ABC() const;
%rename(methodABC) Space::ABC::method(ABC a) const;
namespace Space {
class ABC {
public:
void method(ABC a) const {}
operator ABC() const { ABC a; return a; }
};
}
Note that qualifying the conversion operator previously may or may not have matched.
Now it definitely won't, so this will not match:
%rename(opABC) Space::ABC::operator Space::ABC() const;
in the same way that this does not match:
%rename(methodABC) Space::ABC::method(Space::ABC a) const;
The documentation has been improved with respect to %rename, namespaces and templates.
Conversion operators documentation too.

Fixed Ruby documentation to use the proper css styles for

Made rdoc documentation spit out the full name of the class +

the method, this is still needed to disambiguate between different
classes with similar methods (rdoc was created to document the

I have patched rdoc to make it more friendly to swig. This

STL files have been upgraded to follow the new swig/python
Lib/std conventions.
This means std::vector, std::set, std::map, set::multimap,

ruby objects (swig::GC_VALUE) and several other ruby
enhancements.
std::complex, std::ios, std::iostream, std::iostreambuf and
std::sstream are now also supported.
std::wstring, std::wios, std::wiostream, std::wiostreambuf
and std::wsstream are supported verbatim with no unicode
conversion.
std_vector.i now mimics the behavior of Ruby Arrays much more
closely, supporting slicing, shifting, unshifting,
multiple indexing and proper return values on assignment.
COMPATABILITY NOTE: this changes the older api a little bit in
that improper indexing would previously (incorrectly) raise
exceptions. Now, nil is returned instead, following ruby's
standard Array behavior.

Changed the value of SWIG_TYPECHECK_BOOL to be 10000 (ie. higher

Improved the documentation to document the new features

05/01/2007: gga
[Ruby]
Added %initstack and %ignorestack directives for director
functions. These allow you to control whether a director
function should re-init the Ruby stack.
This is sometimes needed for an embedded Ruby where the
director method is used as a C++ callback and not called
by the user from ruby code.
Explanation:
Ruby's GC needs to be aware of the running OS stack in order to
mark any VALUE (Ruby objects) it finds there to avoid collection
of them. This allows the ruby API to be very simple and allows
you to write code like "VALUE a = sth" anywhere without needing
to do things like refcounting like python.
By default, the start of the stack is set when ruby_init() is
called. If ruby is inited within main(), as it usually is the
case with the main ruby executable, ruby will be able to calculate
its stack properly. However, when this is not possible, as when
ruby is embedded as a plugin to an application where main is not
available, ruby_init() will be called in the wrong place, and
ruby will be incorrectly tracking the stack from the function
that called ruby_init() forwards only, which can lead to
all sorts of weird crashes or to ruby thinking it has run out of
stack space incorrectly.
To avoid this, director (callback) functions can now be tagged
to try to reset the ruby stack, which will solve the issues.
NOTE: ruby1.8.6 still contains a bug in it in that its function
to reset the stack will not always do so. This bug is triggered
very rarely, when ruby is called from two very distinct places
in memory, like a branch of main() and another dso. This bug
has now been reported to ruby-core and is pending further
investigation.

%feature("numoutputs","0") added.
This feature allows you to ignore the output of a function so

%feature("directors"=1)
%include <typemaps.i>
%feature("numoutputs","0") { Class::member_function1 };
%typemap(out) MStatus { // some code, like check mstatus
// and raise exception if wrong };

// MStatus is discarded as a return (out) parameter.

[Internals] Major overhaul of C/C++ scanning implementation. For quite
some time, SWIG contained two completely independent C/C++ tokenizers--
the legacy scanner in CParse/cscanner.c and a general purpose scanner
in Swig/scanner.c. SWIG still has two scanning modules, but the C parser
scanner (CParse/cscanner.c) now relies upon the general purpose
scanner found in Swig/scanner.c. As a result, it is much smaller and
less complicated. This change also makes it possible to maintain all
of the low-level C tokenizing in one central location instead of two
places as before.
***POTENTIAL FLAKINESS***
This change may cause problems with accurate line number reporting
as well as error reporting more generally. I have tried to resolve this
as much as possible, but there might be some corner cases.

10/29/2006: wsfulton
[Java] Important fix to prevent early garbage collection of the Java proxy class
while it is being used in a native method. The finalizer could destroy the underlying
C++ object while it was being used. The problem occurs when the proxy class is no
longer strongly reachable after a native call. The problem seems to occur in
memory stress situations on some JVMs. It does not seem to occur on the
Sun client JVM up to jdk 1.5. However the 1.6 client jdk has a more aggressive garbage
collector and so the problem does occur. It does occur on the Sun server
JVMs (certainly 1.4 onwards). The fix entails passing the proxy class into the native
method in addition to the C++ pointer in the long parameter, as Java classes are not
collected when they are passed into JNI methods. The extra parameter can be suppressed
by setting the nopgcpp attribute in the jtype typemap to "1" or using the new -nopgcpp
commandline option.
See Java.html#java_pgcpp for further details on this topic.

[Chicken] Minor fix to make SWIG work with the (as yet unreleased) chicken 2.5
[Guile,Chicken] Fix SF Bug 1573892. Added an ext_test to the test suite to test
this bug, but this test can not really be made generic because the external code must
plug into the target language interpreter directly.

[C#, Java] Marginally better support for multiple inheritance only in that you can
control what the base class is. This is done using the new 'replace' attribute in the
javabase/csbase typemap, eg in the following, 'Me' will be the base class,
no matter what Foo is really derived from in the C++ layer.
%typemap(javabase, replace="1") Foo "Me"
%typemap(csbase, replace="1") Foo "Me"
Previously it was not possible for the javabase/csbase typemaps to override the C++ base.

[php] Overload resolution now works. However to allow this, SWIG

09/13/2006: wsfulton
The explicitcall feature has been scrapped. This feature was introduced primarily
to solve recursive director method calls. Director upcall improvements made instead:
[Python, Ruby, Ocaml] The swig_up flag is no longer used. The required mutexes
wrapping this flag are also no longer needed. The recursive calls going from C++
to the target language and back again etc are now avoided by a subtlely different
approach. Instead of using the swig_up flag in each director method to indicate
whether the explicit C++ call to the appropriate base class method or a normal
polymorphic C++ call should be made, the new approach makes one of these calls
directly from the wrapper method.
[Java, C#] The recursive call problem when calling a C++ base class method from
Java/C# is now fixed. The implementation is slightly different to the other languages
as the detection as to whether the explicit call or a normal polymorphic call is made
in the Java/C# layer rather than in the C++ layer.
09/11/2006: mgossage

need adjusting - you can easily fix them to work with both old
and new SWIG by changing to use SWIG_ErrorMsg and adding:
#ifndef SWIG_ErrorMsg
#define SWIG_ErrorMsg() ErrorMsg()

Generate wrappers for constants when in C++ or -cwrap mode.
Make -cwrap the default, since it is most correct. Users
can use the -nocwrap option to avoid the creation of a .cxx
file when interfacing to C code.
When in -nocwrap mode, improve the handling of converting
infix literals to prefix notation for lisp. This is very
basic and not likely to be improved upon since this only
applies to the -nocwrap case. Literals we can't figure out
will result in a warning and be included in the generated

[Java]
Removed extra (void *) cast when casting pointers to and from jlong as this
was suppressing gcc's "dereferencing type-punned pointer will break strict-aliasing rules"
warning. This warning could be ignored in versions of gcc prior to 4.0, but now the
warning is useful as gcc -O2 and higher optimisation levels includes -fstrict-aliasing which
generates code that doesn't work with these casts. The assignment is simply never made.
Please use -fno-strict-aliasing to both suppress the warning and fix the bad assembly
code generated. Note that the warning is only generated by the C compiler, but not
the C++ compiler, yet the C++ compiler will also generate broken code. Alternatively use
-Wno-strict-aliasing to suppress the warning for gcc-3.x. The typemaps affected
are the "in" and "out" typemaps in java.swg and arrays_java.swg. Users ought to fix
their own typemaps to do the same. Note that removal of the void * cast simply prevents
suppression of the warning for the C compiler and nothing else. Typical change:
From:
%typemap(in) SWIGTYPE * %{ $1 = *($&1_ltype)(void *)&$input; %}
To:
%typemap(in) SWIGTYPE * %{ $1 = *($&1_ltype)&$input; %}
From:
%typemap(out) SWIGTYPE * %{ *($&1_ltype)(void *)&$result = $1; %}
To:
%typemap(out) SWIGTYPE * %{ *($&1_ltype)&$result = $1; %}

02/22/2006: mmatus
When using directors, now swig will emit all the virtual
protected methods by default.
In previous releases, you needed to use the 'dirprot'
option to achieve the same.
If you want, you can disable the new default behaviour,
use the 'nodirprot' option:
swig -nodirprot ...
and/or the %nodirector feature for specific methods, i.e.:
%nodirector Foo::bar;
struct Foo {
virtual ~Foo();
protected:
virtual void bar();
};
As before, pure abstract protected members are allways
emitted, independent of the 'dirprot/nodirprot' options.
02/22/2006: mmatus
Add the factory.i library for languages using the UTL (python,tcl,ruby,perl).
factory.i implements a more natural wrap for factory methods.
For example, if you have:
---- geometry.h --------
struct Geometry {
enum GeomType{
POINT,
CIRCLE
};
virtual ~Geometry() {}
virtual int draw() = 0;
//
// Factory method for all the Geometry objects
//
static Geometry *create(GeomType i);
};
struct Point : Geometry {
int draw() { return 1; }
double width() { return 1.0; }
};
struct Circle : Geometry {
int draw() { return 2; }
double radius() { return 1.5; }
};
//
// Factory method for all the Geometry objects
//
Geometry *Geometry::create(GeomType type) {
switch (type) {
case POINT: return new Point();
case CIRCLE: return new Circle();
default: return 0;
}
}
---- geometry.h --------
You can use the %factory with the Geometry::create method as follows:
%newobject Geometry::create;
%factory(Geometry *Geometry::create, Point, Circle);
%include "geometry.h"
and Geometry::create will return a 'Point' or 'Circle' instance
instead of the plain 'Geometry' type. For example, in python:
circle = Geometry.create(Geometry.CIRCLE)
r = circle.radius()
where 'circle' now is a Circle proxy instance.

[MzScheme] Typemaps for all integral types now accept the full range of integral
values, and they signal an error when a value outside the valid range is passed.
[Guile] Typemaps for all integral types now signal an error when a value outside
the valid range is passed.
02/13/2006: mgossage
[Documents] updated the extending documents to give a skeleton swigging code
with a few typemaps.
[Lua] added an extra typemap for void* [in], so a function which requires a void*
can take any kind of pointer
Version 1.3.28 (February 12, 2006)
==================================
02/11/2006: mmatus
Fix many issues with line counting and error reports.
02/11/2006: mmatus
[Python] Better static data member support, if you have
struct Foo {
static int bar;
};
then now is valid to access the static data member, ie:
f = Foo()
f.bar = 3
just as in C++.
02/11/2006: wsfulton
[Perl]
Fixed code generation to work again with old versions of Perl
(5.004 and later tested)
02/04/2006: mmatus
[Python] Add the %extend_smart_pointer() directive to extend
SWIG smart pointer support in python.
For example, if you have a smart pointer as:
template <class Type> class RCPtr {
public:
...
RCPtr(Type *p);
Type * operator->() const;
...
};
you use the %extend_smart_pointer directive as:
%extend_smart_pointer(RCPtr<A>);
%template(RCPtr_A) RCPtr<A>;
then, if you have something like:
RCPtr<A> make_ptr();
int foo(A *);
you can do the following:
a = make_ptr();
b = foo(a);
ie, swig will accept a RCPtr<A> object where a 'A *' is
expected.
Also, when using vectors
%extend_smart_pointer(RCPtr<A>);
%template(RCPtr_A) RCPtr<A>;
%template(vector_A) std::vector<RCPtr<A> >;
you can type
a = A();
v = vector_A(2)
v[0] = a
ie, an 'A *' object is accepted, via implicit conversion,
where a RCPtr<A> object is expected. Additionally
x = v[0]
returns (and sets 'x' as) a copy of v[0], making reference
counting possible and consistent.
%extend_smart_pointer is just a collections of new/old
tricks, including %typemaps and the new %implicitconv
directive.
02/02/2006: mgossage
bugfix #1356577, changed double=>lua_number in a few places.
added the std::pair wrapping
01/30/2006: wsfulton
std::string and std::wstring member variables and global variables now use
%naturalvar by default, meaning they will now be wrapped as expected in all languages.
Previously these were wrapped as a pointer rather than a target language string.
It is no longer necessary to add the following workaround to wrap these as strings:
%apply const std::string & { std::string *}
*** POTENTIAL INCOMPATIBILITY ***
01/28/2006: mkoeppe
[Guile -scm]
Add typemaps for handling of member function pointers.
01/24/2006: mmatus
- Better support for the %naturalvar directive, now it
works with the scripting languages as well as
Java/C#.
Now, it can also be applied to class types:
%naturalvar std::string;
%include <std_string.i>
that will tell swig to use the 'natural' wrapping
mechanism to all std::string global and member
variables.
- Add support for the %allowexcept feature along the
scripting languages, which allows the %exception feature
to be applied to the variable access methods. Also, add
the %exceptionvar directive to specify a distintic
exception mechanism only for variables.
- Add more docs for the %delobject directive to mark a method as a
destructor, 'disowning' the first argument. For example:
%newobject create_foo;
%delobject destroy_foo;
Foo *create_foo() { return new Foo(); }
void destroy_foo(Foo *foo) { delete foo; }
or in a member method as:
%delobject Foo::destroy;
class Foo {
public:
void destroy() { delete this;}
private:
~Foo();
};
01/24/2006: mgossage
[Lua]
- Removed the type swig_lua_command_info & replace with luaL_reg
(which then broke the code), fixed this
- added an additional cast in the typemaps for enum's
due to the issue that VC.Net will not allow casting of
a double to an enum directly. Therefore cast to int then to enum
(thanks to Jason Rego for this observation)
01/16/2006: mmatus (Change disabled... will be back in CVS soon)
Add initial support for regexp via the external library
RxSpencer. SWIG doesn't require this library to compile
and/or run. But if you specify --with-rxspencer, and the
library is found during installation, then swig will use
it in three places:
- In %renames rules, via the new rxsmatch rules, for example:
%rename("%(lowercase)",rxsmatch$name="GSL_.*") "";
%rename("%(lowercase)",rxsmatch$nodeType="enum GSL_.*") "";
rxsmatch is similar to the match rule, it just uses
the RxSpencer regexp library to decide if there is a
match with the provided regexp. As with the match
rule, you can also use the negate rule notrxsmatch.
- In the %rename target name via the rxstarget option, for example:
%rename("%(lowercase)",rxstarget=1) "GSL_.*";
where the target name "GSL.*" is now understood as a
regexp to be matched.
- In the new encoder "rxspencer", which looks like:
%(rxspencer:[regexp][replace])s
where "regexp" is the regular expression and "replace"
is a string used as a replacement, where the @0,@1,...,@9
pseudo arguments are used to represent the
corresponding matching items in the reg expression.
For example:
%(rxspencer:[GSL.*][@0])s <- Hello ->
%(rxspencer:[GSL.*][@0])s <- GSLHello -> GSLHello
%(rxspencer:[GSL(.*)][@1])s <- GSLHello -> Hello
%(rxspencer:[GSL(.*)][gsl@1])s <- GSLHello -> gslHello
Another example could be:
%rename("%(lowercase)s",sourcefmt="%(rxspencer:[GSL_(.*)][@1])s",%$isfunction) "";
which take out the prefix "GSL_" and returns all the
function names in lower cases, as following:
void GSL_Hello(); -> hello();
void GSL_Hi(); -> hi();
const int GSL_MAX; -> GSL_MAX; // no change, is not a function
We use the RxSpencer as an initial test bed to
implemention while we decide which library will be
finally added to swig.
You can obtain the RxSpencer library from
http://arglist.com/regex (Unix)
or
http://gnuwin32.sourceforge.net/packages.html (Windows)
Once installed, use "man rxspencer" to get more info
about the regexp format, or just google rxspencer.
Since now you can enable the rxsmatch rules (see above),
the simple or '|' support for the match rules
(01/12/2006: mmatus) is disabled. Still, if you have
problems with the rxspencer library, you can re-enable
the simple 'match or' support using
-DSWIG_USE_SIMPLE_MATCHOR.
01/16/2006: mmatus
Change the %rename predicates to use the prefix '%$', as in:
%rename("%(utitle)s",%$isfunction,%$ismember) "";
to avoid clashes with other swig macros/directives.
01/14/2006: cfisavage
[Ruby]
Added support for Ruby bang! methods via a new %bang feature.
Bang methods end in exclamation points and indicate that the
object being processed will be modified in-place as
opposed to being copied.
01/12/2006: cfisavage
[Ruby]
Updated the Ruby module to automatically convert
method names to lower_case_with_underscores using the
new %rename functionality.
01/12/2006: mmatus
- Add aliases for 'case' encoders used with %rename/%namewarn
%(uppercase)s hello_world -> HELLO_WORLD
%(lowercase)s HelloWorld -> helloworld
%(camelcase)s hello_world -> HelloWorld
%(undercase)s HelloWorld -> hello_world
01/12/2006: mmatus
- Add the -dump_parse_module and -dump_parse_top options,
which are similar to -dump_module and -dump_top, but they
dump the node trees just after parsing, showing only the
attributes visible at the parsing stage, and not the added
later in typemap.cxx, allocate.cxx, lang.cxx or elsewhere.
Besides debugging porpuses, these options are very useful
if you plan to use %rename in an "advance way", since it
shows only and all the node's attributes you can use
inside the match rules.
01/12/2006: mmatus
- Add predicates to %rename, so, you don't need to
remember, for example, how to match a member function.
Now it is easy, for example to use the 'utitle' encoder
in all the member methods, you type:
%rename("%(utitle)s",%isfunction,%ismember) "";
or to ignore all the enumitems in a given class:
%rename("$ignore", %isenumitem, %classname="MyClass") "";
Available predicates are (see swig.swg):
%isenum
%isenumitem
%isaccess
%isclass
%isextend
%isextend
%isconstructor
%isdestructor
%isnamespace
%istemplate
%isconstant
%isunion
%isfunction
%isvariable
%isimmutable
%isstatic
%isfriend
%istypedef
%isvirtual
%isexplicit
%isextern
%ismember
%isglobal
%innamespace
%ispublic
%isprotected
%isprivate
%classname
These predicates correspond to specific 'match'
declarations, which sometimes are not as evident as the
predicates names.
- Add the or '|' operation in %rename match, for
example to capitalize all the constants (%constant or
const cdecl):
%rename("%(upper)s",match="cdecl|constant",%isimmutable) "";
01/12/2006: mgossage
- Partial fixed of errors under C89, bug #1356574
(converted C++ style comments to C style)
- Added patches from neomantra@users.sf.net #1379988 and #1388343
missing a 'return' statement for error conditions
also updated the %init block bug #1356586
01/10/2006: mmatus
- Add the 'utitle' encoder, as an example of how to add
your own encoder. I added the encoder method in misc.c
but developers can add others, the same way, inside any
target language.
Well, 'utitle' is the reverse of 'ctitle', ie:
%rename("%(ctitle)s") camel_case; -> CamelCase;
%rename("%(utitle)s") CamelCase; -> camel_case;
01/10/2006: cfisavage
[Ruby]
Updated Ruby Exception handling. Classes that are specified in throws clauses,
or are marked as %exceptionclass, are now inherited from rb_eRuntimeError.
This allows instances of these classes to be returned to Ruby as exceptions.
Thus if a C++ method throws an instance of MyException, the calling Ruby
method will get back a MyException object. To see an example,
look at ruby/examples/exception_class.
01/10/2006: mmatus
- Add the %catches directive, which complements the %exception
directive in a more automatic way. For example, if you have
int foo() throw(E1);
swig generates the proper try/catch code to dispatch E1.
But if you have:
int barfoo(int i) {
if (i == 1) {
throw E1();
} else {
throw E2();
}
return 0;
}
ie, where there is no explicit exception specification in the decl, you
end up doing:
%exception barfoo {
try {
$action
} catch(E1) { ... }
} catch(E2) { ... }
}
which is very tedious. Well, the %catches directive defines
the list of exceptions to catch, and from swig:
%catches(E1,E2) barfoo(int i);
int barfoo(int i);
is equivalent to
int barfoo(int i) throw(E1,E2);
Note, however, that the %catches list doesn't have to
correspond to the C++ exception specification. For example, if you
have:
struct E {};
struct E1 : E {};
struct E2 : E {};
int barfoo(int i) throw(E1,E2);
you can define
%catches(E) barfoo(int i);
and swig will generate an action code equivalent to
try {
$action
} catch(E &_e) {
<raise _e>;
}
Of course, you still have to satisfy the C++ restrictions,
and the catches list must be compatible (not the same)
as the original list of types in the exception specification.
Also, you can now specify that you want to catch the
unknown exception '...', for example:
%catches(E1,E2,...) barfoo(int);
In any case, the %catches directive will emit the
code to convert into the target language error/exception
using the 'throws' typemap.
For the '...' case to work, you need to
write the proper typemap in your target language. In the
UTL, this looks like:
%typemap(throws) (...) {
SWIG_exception(SWIG_RuntimeError,"unknown exception");
}
01/09/2006: mutandiz
[Allegrocl]
Fixes a number of SEGVs primarily in the handling of
various anonymous types. Found in a pass through the
swig test-suite. Still more to do here, but this is a
good checkpoint.
Adds -cwrap and -nocwrap as an allegrocl specific
command-line argument. Controls generating of a C
wrapper file when wrapping C code. By default only a
lisp file is created for C code wrapping.
Doc updates for the command-line arguments and fixes as
pointed out on swig-devel
01/05/2006: wsfulton
[Java] Fix unsigned long long and const unsigned long long & typemaps
- Bug #1398394 with patch from Dries Decock
01/06/2006: mmatus
Add 'named' warning codes, now in addition to:
%warnfilter(813);
you can use
%warnfilter(SWIGWARN_JAVA_MULTIPLE_INHERITANCE);
just use the same code name found in Source/Include/swigwarn.h
plus the 'SWIG' prefix.
If a developer adds a new warning code, the Lib/swigwarn.swg file
will be generated when running the top level make.
01/05/2006: cfisavage
[Ruby]
Reimplemented object tracking for Ruby. The new implementation works
by expanding the swig_class structure for Ruby by adding a trackObjects
field. This field can be set/unset via %trackobjects as explained
in the Ruby documentation. The new implementation is more robust
and takes less code to implement.
01/05/2006: wsfulton
Fix for %extend and static const integral types, eg:
class Foo {
public:
%extend {
static const int bar = 42;
}
};
12/30/2005: mmatus
- Add info for old and new debug options:
-dump_top - Print information of the entire node tree, including system nodes
-dump_module - Print information of the module node tree, avoiding system nodes
-dump_classes - Print information about the classes found in the interface
-dump_typedef - Print information about the types and typedefs found in the interface
-dump_tags - Print information about the tags found in the interface
-debug_typemap - Print information for debugging typemaps
-debug_template - Print information for debugging templates
- Add the fakeversion. If you have a project that uses
configure/setup.py, or another automatic building system
and requires a specific swig version, let say 1.3.22
you can use:
SWIG_FEATURES="-fakeversion 1.3.22"
or
swig -fakeversion 1.3.22
and then swig -version will report 1.3.22 instead of the
current version.
Typical use would be
SWIG_FEATURES="-fakeversion 1.3.22" ./configure
12/30/2005: mmatus
- Add option/format support to %rename and %namewarn.
Now %namewarn can force renaming, for example:
%namewarn("314: import is a keyword",rename="_%s") "import";
and rename can also support format forms:
%rename("swig_%s") import;
Now, since the format is processed via swig Printf, you
can use encoders as follows:
%rename("%(title)s") import; -> Import
%rename("%(upper)s") import; -> IMPORT
%rename("%(lower)s") Import; -> import
%rename("%(ctitle)s") camel_case; -> CamelCase
This will allow us to add more encoders, as the
expected one for regular expressions.
- Add the above 'ctitle' encoder, which does the camel case:
camel_case -> CamelCase
- Also, while we get the regexp support, add the 'command' encoder,
you can use it as follows
%rename("%(command:sed -e 's/\([a-z]\)/\U\\1/' <<< )s") import;
then swig will popen the command
"sed -e 's/\([a-z]\)/\U\\1/' <<< import"
see below for anonymous renames for better examples.
- The rename directive now also allows:
- simple match: only apply the rename if a type match
happen, for example
%rename(%(title)s,match="enumitem") hello;
enum Hello {
hi, hello -> hi, Hello
};
int hello() -> hello;
- extended match: only apply the rename if the 'extended attribute' match
occurred, for example:
// same as simple match
%rename(%(title)s,match$nodeType="enumitem") hello;
enum Hello {
hi, hello -> hi, Hello
};
Note that the symbol '$' is used to define the attribute name in
a 'recursive' way, for example:
// match only hello in 'enum Hello'
%rename(%(title)s,match$parentNode$type="enum Hello") hello;
enum Hello {
hi, hello -> hi, Hello // match
};
enum Hi {
hi, hello -> hi, hello // no match
};
here, for Hello::hi, the "parentNode" is "Hello", and its "type"
is "enum Hello".
- Anonymous renames: you can use 'anonymous' rename directives, for example:
// rename all the enum items in Hello
%rename(%(title)s,match$parentNode$type="enum Hello") "";
enum Hello {
hi, hello -> Hi, Hello // match both
};
enum Hi {
hi, hello -> hi, hello // no match
};
// rename all the enum items
%rename(%(title)s,match$nodeType="enumitem") "";
// rename all the items in given command (sloooow, but...)
%rename(%(command:<my external cmd>)s) "";
Anonymous renames with commands can be very powerful, since you
can 'outsource' all the renaming mechanism (or part of it) to an
external program:
// Uppercase all (and only) the names that start with 'i'
%rename("%(command:awk '/^i/{print toupper($1)}' <<<)s") "";
int imported() -> IMPORTED;
int hello() -> hello
Note that if the 'command' encoder returns an empty string, swig
understands that no rename is necessary.
Also note that %rename 'passes' the matched name. For example, in
this case
namespace ns1 {
int foo();
}
namespace ns2 {
int bar();
}
the external program only receives "foo" and "bar". If needed,
however, you can request the 'fullname'
%rename("%(command:awk 'awk '/ns1::/{l=split($1,a,"::"); print toupper(a[l])}'' <<<)s",fullname=1) "";
ns1::foo -> FOO
ns2::bar -> bar
- Mixing encoders and matching: of course, you can do mix commands
and match fields, for example:
%rename("%(<my encoder for fncs>)",match="cdecl") "";
%rename("%(<my encoder for enums>)",match="enumitem") "";
%rename("%(<my encoder for enums inside a class>)",match="enumitem",
match$parentNode$parentNode$nodeType="class") "";
Use "swig -dump_parse_module" to see the attribute names you can use to
match a specific case.
- 'sourcefmt' and 'targetfmt': sometimes you need to
process the 'source' name before comparing, for example
%namewarn("314: empty is a keyword",sourcefmt="%(lower)s") "empty";
then if you have
int Empty(); // "Empty" is the source
you will get the keyword warning since 'Empty' will be
lower cased, via the sourcefmt="%(lower)s" option,
before been compared to the 'target' "empty".
There is an additional 'targetfmt' option to process the
'target' before comparing.
- complementing 'match': you can use 'notmatch', for example
%namewarn("314: empty is a keyword",sourcefmt="%(lower)s",notmatch="namespace") "empty";
here, the name warning will be applied to all the symbols except namespaces.
12/30/2005: mmatus
- Add initial support for gcj and Java -> <target language> mechanism.
See examples in:
Examples/python/java
Examples/ruby/java
Examples/tcl/java
to see how to use gcj+swig to export java classes into
python/ruby/tcl.
The idea is to put all the common code for gcj inside
Lib/gcj
and localize specific types such as jstring, as can be found
in
Lib/python/jstring.i
Lib/ruby/jstring.i
Lib/tcl/jstring.i
Using the UTL, this is very easy, and the perl version for
jstring.i will be next.
12/29/2005: mmatus
- Add the copyctor feature/directive/option to enable the automatic
generation of copy constructors. Use as in:
%copyctor A;
struct A {
};
then this will work
a1 = A();
a2 = A(a1);
Also, since it is a feature, if you just type
%copyctor;
that will enable the automatic generation for all the
classes. It is also equivalent to
swig -copyctor -c++ ...
Notes:
1.- The feature only works in C++ mode.
2.- The automatic creation of the copy constructor will
usually produce overloading. Hence, if the target
language doesn't support overloading, a special name
will be used (A_copy).
3.- For the overloading reasons above, it is probably not
a good idea to use the flag when, for example, you are
using keywords in Python.
4.- The copyctor automatic mechanism follows more or less
the same rules as the default constructor mechanism,
i.e., a copy constructor will not be added if the
class is abstract or if there is a pertinent non-public
copy ctor in the class or its hierarchy.
Hence, it might be necessary for you to complete the
class declaration with the proper non-public copy ctor
to avoid a wrong constructor addition.
- Fix features/rename for templates ctor/dtor and other
things around while adding the copyctor mechanism.
12/27/2005: mmatus
- Add the 'match' option to typemaps. Assume you have:
%typemap(in) SWIGTYPE * (int res) {..}
%typemap(freearg) SWIGTYPE * { if (res$argnum) ...}
then if you do
%typemap(in) A * {...}
swig will 'overload the 'in' typemap, but the 'freearg'
typemap will be also applied, even when this is wrong. The old
solutions is to write:
%typemap(in) A * {...}
%typemap(freeag) A * ""
overload 'freearg' with an empty definition.
The problem is, however, there is no way to know you need
to do that until you start getting broken C++ code, or
worse, broken runtime code.
The same applies to the infamous 'typecheck' typemap,
which always confuses people, since the first thing you do
is to just write the 'in' typemap.
The 'match' option solves the problem, and if instead you write:
%typemap(in) SWIGTYPE * (int res) {..}
%typemap(freearg,match="in") SWIGTYPE * { if (res$argnum) ...}
%typemap(typecheck,match="in",precedence...) SWIGTYPE * {...}
it will tell swig to apply the 'freearg/typecheck'
typemaps only if they 'match' the type of the 'in'
typemap. The same can be done with other typemaps as:
%typemap(directorout) SWIGTYPE * {...}
%typemap(directorfree,match="directorout") SWIGTYPE * {...}
12/27/2005: mmatus
- Add the 'naturalvar' option/mode/feature to treat member
variables in a more natural way, ie, similar to the global
variable behavior.
You can use it in a global way via the command line
swig -naturalvar ...
or the module mode option
%module(naturalvar=1)
both forms make swig treat all the member variables in the
same way it treats global variables.
Also, you can use it in a case by case approach for
specific member variables using the directive form:
%naturalvar Bar::s;
Then, in the following case for example:
std::string s;
struct Bar {
std::string s;
};
you can do:
b = Bar()
b.s ="hello"
cvar.s = "hello"
if (b.s != cvar.s):
raise RuntimeError
This is valid for all the languages, and the
implementation is based on forcing the use of the
const SWIGTYPE& (C++)/SWIGTYPE (C) typemaps for the
get/set methods instead of the SWIGTYPE * typemaps.
Hence, for 'naturalvar' to work, each target language
must implement 'typemap(in/out) const Type&' properly.
The 'naturalvar' option replaces or makes workarounds such as:
%apply const std::string & { std::string *}
unnecessary.
Note1: If your interface has other kinds of workarounds to
deal with the old 'unnatural' way to deal with member
variables (returning/expecting pointers), the
'naturalvar' option could break them.
Note2: the option has no effect on unnamed types, such
as unnamed nested unions.
12/27/2005: mmatus
- Add more 'expressive' result states for the typemap
libraries.
In the past, for scripting languages, you would do checking something like:
if (ConvertPtr(obj,&vptr,ty,flags) != -1) {
// success
} else {
// error
}
Now the result state can carry more information,
including:
- Error state: like the old -1/0, but with error codes from swigerrors.swg.
int res = ConvertPtr(obj,&vptr,ty,flags);
if (SWIG_IsOK(res)) {
// success code
} else {
SWIG_Error(res); // res carries the error code
}
- Cast rank: when returning a simple successful
conversion, you just return SWIG_OK, but if you need
to do a 'cast', you can add the casting rank, ie:
if (PyFloat_Check(obj)) {
value = PyFloat_AsDouble(obj);
return SWIG_OK;
} else if (PyInt_Check(obj)) {
value = (double) PyInt_AsLong(obj);
return SWIG_AddCast(SWIG_OK);
}
later, the casting rank is used to properly dispatch
the overloaded function, for example. This of course
requires your language to support and use the new
dispatch cast/rank mechanism (Now mainly supported in
perl and python, and easily expandable to ruby and tcl).
- [UTL] Add support for the new 'expressive' result states.
12/27/2005: mmatus
- Add support for the C++ implicit conversion mechanism, which
required some modifications in parser.y (to recognize
'explicit') and overload.cxx (to replace $implicitconv as
needed).
Still, real support in each target language requires each
target language to be modified. Python provides an example,
see below.
- Add support for native C++ implicit conversions, ie, if you
have
%implicitconv A;
struct A {
int ii;
A() {ii = 1;}
A(int) {ii = 2;}
A(double) {ii = 3;}
explicit A(char *s) {ii = 4;}
};
int get(const A& a) {return a.ii;}
you can call:
a = A()
ai = A(1)
ad = A(1.0)
as = A("hello")
# old forms
get(a) -> 1
get(ai) -> 2
get(ad) -> 3
get(as) -> 4
#implicit conversions
get(1) -> 2
get(1.0) -> 3
get("hello") -> Error, explicit constructor
Also, as in C++, now implicit conversions are supported in
variable assigments, and if you have:
A ga;
struct Bar {
A a;
};
you can do:
cvar.ga = A(1)
cvar.ga = 1
cvar.ga = 1.0
cvar.ga = A("hello")
cvar.ga = "hello" -> error, explicit constructor
b = Bar()
b.a = A("hello")
b.a = 1
b.a = 1.0
b.a = "hello" -> error, explicit constructor
Note that the last case, assigning a member var directly,
also requires the 'naturalvar' option.
This support now makes the old '%implicit' macro, which
was found in 'implicit.i' and it was fragile in many ways,
obsolete, and you should use the new '%implicitconv'
directive instead.
Note that we follow the C++ conventions, ie, in the
following the implicit conversion is allowed:
int get(A a) {return a.ii;}
int get(const A& a) {return a.ii;}
but not in these cases:
int get(A *a) {return a->ii;}
int get(A& a) {return a.ii;}
Also, it works for director methods that return a by value
result, ie, the following will work:
virtual A get_a() = 0;
def get_a(self):
return 1
but not in this case:
virtual const A& get_a() = 0;
virtual A& get_a() = 0;
virtual A* get_a() = 0;
Notes:
- the implicitconv mechanism is implemented by directly
calling/dispatching the python constructor, triggering a
call to the __init__method. Hence, if you expanded the
__init__ method, like in:
class A:
def __init__(self,args):
<swig code>
<my code here>
then 'my code' will also be executed.
- Since the %implicitconv directive is a SWIG feature, if you type:
%implicitconv;
that will enable implicit conversion for all the classes in
your module.
But if you are worried about performance, maybe that will be
too much, especially if you have overloaded methods, since
to resolve the dispatching problem, python will efectively
try to call all the implicit constructors as needed.
- For the same reason, it is highly recommended that you use
the new 'castmode' when mixing implicit conversion and
overloading.
- [python] The %implicit directive is declared obsolete, and
you should use %implicitconv instead. If you include
the implicit.i file, a warning will remind you of this.
Note: Since %implicit is fragile, just replacing it by
%implicitconv could lead to different behavior. Hence, we
don't automatically switch from to the other, and the user
must migrate to the new %implicitconv directive manually.

[C#]
Modify std::vector wrappers to use std::vector::value_type as this is
closer to the real STL declarations for some methods, eg for push_back().
Fixes some compilation errors for some compilers eg when the templated
type is a pointer.
[Java]
std::vector improvements - a few more methods are wrapped and specializations are
no longer required. The specialize_std_vector macro is no longer needed (a
warning is issued if an attempt is made to use it).
12/26/2005: wsfulton
[Java, C#]
Add in pointer reference typemaps. This also enables one to easily wrap
std::vector<T> where T is a pointer.
12/24/2005: efuzzyone
[CFFI] The cffi module for SWIG:
- Fully supports C, but provides limited supports for C++, in
particular C++ support for templates and overloading needs to
be worked upon.
12/23/2005: mmatus
[python] Add the castmode that allows the python
type casting to occur.
For example, if you have 'int foo(int)', now
class Ai():
def __init__(self,x):
self.x = x
def __int__(self):
return self.x
foo(1) // Ok
foo(1.0) // Ok
foo(1.3) // Error
a = Ai(4)
foo(ai) // Ok
The castmode, which can be enabled either with the
'-castmode' option or the %module("castmode") option, uses
the new cast/rank dispatch mechanism. Hence, now if you
have 'int foo(int); int foo(double);', the following works
as expected:
foo(1) -> foo(int)
foo(1.0) -> foo(double)
ai = Ai(4)
foo(ai) -> foo(int)
Note1: the 'castmode' could disrupt some specialized
typemaps. In particular, the "implicit.i" library seems to
have problem with the castmode. But besides that one, the
entire test-suite compiles fine with and without the
castmode.
Note2: the cast mode can't be combined with the fast
dispatch mode, ie, the -fastdispatch option has no effect
when the cast mode is selected. The penalties, however,
are minimum since the cast dispatch code is already based
on the same fast dispatch mechanism.
See the file overload_dispatch_cast_runme.py file for
new cases and examples.
12/22/2005: mmatus
Add the cast and rank mechanism to dispatch overloading
functions. The UTF supports it now, but for each language
it must be decided how to implement and/or when to use it.
[perl] Now perl uses the new cast and rank dispatch
mechanism, which solves all the past problems known
in perl, such as the old '+ 1' problem:
int foo(int);
$n = 1
$n = $n + 1
$r = foo(n)
also works:
foo(1);
foo("1");
foo(1.0);
foo("1.0");
but fails
foo("l");
and when overloading foo(int) and foo(double);
foo(1) -> foo(int)
foo(1.0) -> foo(double)
foo("1") -> foo(int)
foo("1.0") -> foo(double)
foo("l") -> error
foo($n) -> foo(int) for good perl versions
foo($n) -> foo(double) for old bad perl versions
when overloading foo(int), foo(char*) and foo(double):
foo(1) -> foo(int)
foo(1.0) -> foo(double)
foo("1") -> foo(char*)
foo("1.0") -> foo(char*)
foo("l") -> foo(char*)
Note: In perl the old dispatch mechanism was broken,
so, we don't provide an option to enable the old one
since, again, it was really really broken.
See 'overload_simple_runme.pl' for more cases and tests.
PS: all the old known issues are declared resolved, any
new "problem" that could be discovered is declared,
a priori, as "features" of the new dispatch mechanism
(until we find another solution at least).
*** POTENTIAL INCOMPATIBILITY ***
As with the introduction of the UTF, some things could
now start to work as expected, and people used to deal or
workaround previous bugs related to the dispatch
mechanism, could see now a difference in perl behavior.
12/21/2005: mmatus
- The '-nodefault' flag (pragma and feature) now generates
a warning, and recommends to use the explicit
-nodefaultctor and -nodefaultdtor options.
The reason to split the 'nodefault' behavior is that, in
general, ignoring the default destructor generates memory
leaks in the target language. Hence, is too risky just to
disable both the default constructor and destructor
at the same time.
If you need to disable the default destructor, it is
also recommended you use the directive form:
%nodefaultdtor MyVerySpecialClass;
for specific classes, and always avoid using the global
-nodefault and -nodefaultdtor options.
12/21/2005: wsfulton
[Java, C#]
Fix incorrect code generation when the intermediary classname is changed
in the module directive from its default. For example:
%module(jniclassname="myimclassnewname") "mymodule" // Java
%module(imclassname="myimclassnewname") "mymodule" // C#
Add in new special variable $imclassname. See docs.
12/17/2005: mmatus
[Python]
- Add the -aliasobj0/-noaliasobj0 options to use with
-fastunpack and/or -O and old typemaps that use 'obj0'
directly.
So, if you compile your code using -O and get errors about
the undeclared 'obj0' variable, run again using
swig -O -aliasobj0 -python ....
For new typemaps, never use 'obj0' directly, if needed,
use the '$self' name that will be properly expanded to
'obj0' (nofastunpack) or 'swig_obj[0]' (fastunpack).
If you have no idea what I am talking about, better, that
means you have no typemap with this problem.
12/14/2005: mmatus
[Python]
- Add the -fastunpack/-nofastunpack options to enable/disable
the use of the internal UnpackTuple method, instead of
calling the one from the python C API.
The option -O now also implies -fastunpack.
12/11/2005: mmatus
[Python]
- Add the -proxydel/-noproxydel options to enable/disable
the generation of proxy/shadow __del__ methods, even
when now they are redundant, since they are empty.
However, old interfaces could rely on calling them.
The default behavior is to generate the __del__ methods
as in 1.3.27 or older swig versions.
The option -O now also implies -noproxydel.
12/10/2005: mmatus
[UTF]
- Fix unnecessary calls to SWIG_TypeQuery for 'char *'
and 'wchar_t *', problem found by Clay Culver while
profiling the PyOgre project.
[Python]
- Add the -dirvtable/-nodirvtable to enable/disable
a pseudo virtual table used for directors, avoiding
the need to resolve the python method at each call.
- Add the -safecstrings/-nosafecstrings options to
enable/disable the use of safe conversions from PyString
to char *. Python requires you to never change the internal
buffer directly, and hence 'safectrings' warranties that
but returning a copy of the internal python string buffer.
The default, as in previous releases, is to return a
pointer to the buffer (nosafecstrings), so, it is the user's
responsibility to avoid its modification.
- Add the -O option to enable all the optimization options
at once, initially equivalent to
-modern -fastdispatch -dirvtable -nosafecstrings -fvirtual
12/08/2005: mmatus
- Add the -fastdispatch option (fastdispatch feature). This
enables the "fast dispatch" mechanism for overloaded
methods provided by Salvador Fandi~no Garc'ia (#930586).
The resulting code is smaller and faster since less type
checking is performed. However, the error messages you
get when the overloading is not resolved could be
different from what the traditional method returns.
With the old method you always get an error such as
"No matching function for overloaded ..."
with the new method you can also get errors such as
"Type error in argument 1 of type ..."
See bug report #930586 for more details.
So, this optimization must be explicitly enabled by users.
The new mechanism can be used as:
swig -fastdispatch
or using the feature form
%feature("fastdispatch") method;
or
%fastdispatch method;
12/06/2005: mmatus
- Several memory and speed improvements, specially for
templates. Now swig is up to 20 faster than before for
large template interfaces, such as the std_containers.i
and template_matrix.i files in the python test-suite.
Memory footprint is also reduced in consideration of small
pcs/architectures.
- add commandline options -cpperraswarn and -nocpperraswarn" to force
the swig preprocessor to treat the #error directive as a #warning.
the pragmas
#pragma SWIG cpperraswarn=1
#pragma SWIG cpperraswarn=0
are equivalent to the command line options, respectively.
12/06/2005: mmatus
[Python] The generated code is now more portable, especially
for Windows. Following
http://www.python.org/doc/faq/windows.html
Py_None is never accessed as a structure, plus other
tricks mentioned there.
12/06/2005: mmatus
[Python] Added initial support for threads based in the
proposal by Joseph Winston.
The user interface is as follows:
1.- the module thread support is enable via the "threads" module
option, i.e.
%module("threads"=1)
2.- Equivalent to that, is the new '-threads' swig option
swig -threads -python ...
3.- You can partially disable thread support for a given
method using:
%feature("nothread") method;
or
%nothread method;
also, you can disable sections of the thread support,
for example
%feature("nothreadblock") method;
or
%nothreadblock method;
%feature("nothreadallow") method;
or
%nothreadallow method;
the first disables the C++/python thread protection, and the
second disables the python/C++ thread protection.
4.- The current thread support is based in the PyGIL
extension present in python version 2.3 or later, but
you can provide the thread code for older versions by
defining the macros in pythreads.swg.
If you get a working implementation for older versions,
please send us a patch.
For the curious about performance, here are some numbers
for the profiletest.i test, which is used to check the speed
of the wrapped code:
nothread 9.6s (no thread code)
nothreadblock 12.2s (only 'allow' code)
nothreadallow 13.6s (only 'block' code)
full thread 15.5s ('allow' + 'block' code)
i.e., full thread code decreases the wrapping performance by
around 60%. If that is important to your application, you
can tune each method using the different 'nothread',
'nothreadblock' or 'nothreadallow' features as
needed. Note that for some methods deactivating the
'thread block' or 'thread allow' code is not an option,
so, be careful.
11/26/2005: wsfulton
SWIG library files use system angle brackets everywhere for %include, eg
%include "std_common.i"
becomes
%include <std_common.i>
11/26/2005: wsfulton
[Java, C#]
Typesafe enums and proper enums have an extra constructor so that enum item values that
are initialised by another enum item value can be wrapped without having to use %javaconstvalue/
%csconstvalue for when using %javaconst(1)/%csconst(1). Suggestion by
Bob Marinier/Douglas Pearson.
For example:
typedef enum
{
xyz,
last = xyz
} repeat;
11/21/2005: mmatus
[ruby + python]
Fixes for directors + pointers. This is an ugly problem without an easy
solution. Before we identified this case as problematic:
virtual const MyClass& my_method();
but it turns out that all the cases where a pointer, array or
reference is returned, are problematic, even for
primitive types (as int, double, char*, etc).
To try to fix the issue, a new typemap was added,
'directorfree', which is used to 'free' the resources
allocated during the 'directorout' phase. At the same
time, a primitive garbage collector engine was added to
deal with orphaned addresses, when needed.
The situation is much better now, but still it is possible to have
memory exhaustation if recursion is used.
So, still you need to avoid returning pointers, arrays or
references when using director methods.
- Added stdint.i - typemaps for latest C99 integral types found in stdint.h.
11/14/2005: wsfulton
More types added to windows.i, eg UINT8, WORD, BYTE etc.
Including windows.i will also enable SWIG to parse the __declspec Microsoft
extension, eg __declspec(dllimport). Also other Windows calling conventions
such as __stdcall.
11/10/2005: wsfulton
New library file for Windows - windows.i. This file will contain useful type
information for users who include windows.h. Initial support is for the
non ISO integral types: __int8, __int16, __int32, __int64 and unsigned versions.
The unsigned versions previously could not be parsed by SWIG. SF #872013.
11/09/2005: wsfulton
[Java, C#] Portability warning for files which will overwrite each other on case
insensitive file systems such as FAT32/NTFS. This will occur, for example, when two
class names are the same barring case. The warning is issued on all platforms and
can be suppressed with the usual warning suppression techniques. SF bug #1084507.
11/09/2005: wsfulton
./configure --with-python --with-ruby --with-perl5 etc enable these languages,
ie the --with-xxxx options, where no path is specified, work the same as if
the option was not specified at all. Based on patches #1335042 #1329048 #1329047.

[Allegrocl]
Add C++ support to the Allegrocl module. Further
enhances the C support as well. Some of the
features:
- MUCH better generation of foreign types based on
the C/C++ types for use in defining the FFI on
the lisp side. We don't pass everything as a (* :void)
any longer.
- Uses typemaps for better control of type conversions
and code generation in the generated lisp and c++ wrapper
code.
- CLOS wrapping of pointers returned from foreign space
makes it easier to differentiate pointers in user code.
The wrapping objects can be passed directly to FF calls.
- Defun wrapping of FF calls, allowing for more lispy
interface. Conversion, GCing, of lisp objects to
foreign objects can be done in the wrapping defun via
the use of typemaps.
- overload dispatching implemented on the lisp side
using generic functions.
- Templates and synonymous types supported.
11/07/2005: mmatus
[Python] Adding proper support for multi-inheritance in
the python side, ie, if you have two C++ wrapped class, Foo
and Bar, now:
class MyPythonClass(Foo,Bar):
....
will properly work, even with directors, and the
deallocation of Foo.this and Bar.this will follow
correctly. Before, a class could only have one 'this'
instance (unlike C++), only the last base class was
properly deleted, or detected with directors.
Now 'self.this' can be a list, which will contain the C++
instance pointers for all the base classes.
Also, swig.this is responsible for deallocating the C++
instance(s), and the __del__ method is not emitted unless
the user preppend/append some code to it.
- Swig can now detect memory leaks, ie, if you still
don't use proxy/shadow classes, and type something like
import _example
f = _example.new_Foo()
and forget to call _example.delete_Foo(f), then swig will
tell you that there is a memory leak.
Otherwise, if you always use the proxy classes, you probably
you will never ever see this warning unless there is
something wrong inside the swig wrapping code.
*** POTENTIAL INCOMPATIBILITY ***
If you overloaded the __del__ method, and call the base
one without a try block, as in
class MyClass(SwigClass):
def __del__(self):
<your code here>
SwigClass.__del__(self)
python could complain that the method SwigClass.__del__ is
undefined. Try to use instead:
def __del__(self):
<your code here>
try: SwigClass.__del__(self)
except: pass
or simply
def __del__(self):
<your code here>
11/02/2005: mmatus
[Python] Adding more fun to STL/STD containers, now you
can do
%template(pyset) std::set<PyObject *>;
%template(pyvector) std::vector<PyObject *>;
%template() std::pair<PyObject *,PyObject *>;
%template(pyvector) std::map<PyObject *,PyObject *>;
....
The same applies to std::list, std::deque, std::multiset, etc.
Then, at the python side you can do now:
# C++ std::vector as native python sequence
v = pyvector([1,"hello",(1,2)])
print v[1]
>> 'hello'
print v[2]
>> (1,2)
# C++ std::set as native python sequence
s = pyset()
s.insert((1,2))
s.insert(1)
s.insert("hello")
sum=()
for i in s:
sum +=(i,)
print sum
>>> (1, 'hello', (1, 2))
# C++ std::map as native python sequence
m = pymap()
m["foo"] = "hello"
m[1] = (1,2)
pm = {}
for k in m:
pm[k] = m[k]
print pm
>>> {1: (1, 2), 'foo': 'hello'}
ie, the STD/STL containers work as real native python
container, with arbitrary item types and so.
But since normal C++ containers do not properly ref/unref
their items, you should use the safer versions:
%template(pyset) std::set<swig::PyObject_ptr>;
%template(pyvector) std::vector<swig::PyObject_ptr>;
%template() std::pair<swig::PyObject_ptr, swig::PyObject_ptr>;
%template(pyvector) std::map<swig::PyObject_ptr,swig::PyObject_ptr>;
....
where swig::PyObject_ptr is a PyObject * envelope class provided
to safely incref/decref the python object.
So, now you can use all the STL/STD containers as native
Python containers.
Note 1: std::map, std::set and the other 'ordered'
containers will properly use PyObject_Compare for sorting,
when needed.
Note 2: all the STL/STD containers have a limit size of
SIZE_MAX, ie, you can have manage containers larger than
INT_MAX, the python limit.
11/02/2005: mmatus
[Python]
- add 'iterator()' method for all sequences and additionally
'key_iterator()' for maps.
'iterator()' will always return the native C++ iterator.
Additionally, in maps, 'key_iterator()' will return a python
iterator using only the map keys.
In general the sequence method __iter__ will call
'iterator()', returning the native C++ iterator, but in
maps it will call 'key_iterator()', maintaining
backward compatibility.
Hence, for std::maps, you can play then with the native
C++ iterator, which value is a (key, value) pair, by
calling map.iterator(), as with map.begin(), map.end(), etc.
The difference is that map.iterator() returns a safe
'closed' iterator, while map.begin() and map.end() are
'open' iterators.
A 'closed' iterator knows the begin and the end of the
sequence, and it never can seg. fault. An 'open'
iterator, as in C++, can seg. fault at the C++ side.
# a closed iterator is safe in the following example.
# the next() method will throw a StopIteration
# exception as needed
i = seq.iterator()
try:
while True:
sum += i.next()
except: pass
# an open iterator always need to be checked,
# or it will crash at the C++ side
current = seq.begin()
end = seq.end()
while (current != end):
sum += current.next()
[Python]
- Finally, when we call
f = Foo()
the construction is 'one-way'. Before construction was done
something like
Foo() (python) -> _new_Foo() (C++)
new_Foo() (C++) -> FooPtr() (python)
FooPtr() (python) -> Foo() (python)
and returning a pointer was done like
NewPointerObj() (C++) -> FooPtr() (python)
FooPtr(python) -> Foo() (python)
ie, we when going back and forward between the C++ and
python side.
Now since there is no FooPtr the construction process is
Foo() (python) -> _new_Foo() (C++)
_new_Foo() (C++) -> NewPointerObj() (C++) (no shadow class)
and returning a pointer is done
NewPointerObj() (C++) (with shadow class) -> NewInstaceObj() (C++)
where NewInstanceObj creates a new instance without
calling __init__ and it doesn't go 'back' to python, is
'pure' C API.
- With this change, and the other ones in the
PySwigObject type, which now carries the thisown and
swig_type_info pointer, the generated code should be as
fast as boost::Python and/or the other python wrappers
based in pure Python/C API calls.
As a reference, the profiletest_runme.py example, which
does a simple call function many times, such as this code:
import profiletest
a = profiletest.A()
b = profiletest.B()
for i in range(0,1000000)
a = b.fn(a)
where fn is defined as 'A* B::fn(A *a) {return a;}',
produces the following times
nomodern modern
swig-1.3.26 19.70s 5.98s
swig-CVS 0.99s 0.98s
Clearly, there is a large improvement for the python
'nomodern' mode. Still, the 'modern' mode is around
6 times faster than before. For the same test, but
using the non-shadow version of the module, we get
_profiletest (non-shadow)
swig-1.3.26 0.80s
swig-CVS 0.60s
Hence, now for practical purposes, the proxy overhead
is insignificant.
Note that the performance numbers we are showing is for
a simple module (two types) and a simple function (one
argument). For real situations, for modules with many
more types and/or functions with many more parameters,
you will see even better results.
10/31/2005: mmatus
[Python]
- Finally, no more ClassPtr proxy classes. You will see
only a clean Class proxy class in the .py file.
- No more 'real' thisown attribute either, the PySwigObject now
carries the ownership info.
You can also do something like
print self.this.own()
>>> True
self.this.disown()
self.this.own(0)
print self.this.own()
>>> False
self.this.acquire()
self.this.own(1)
print self.this.own()
>>> True
Still the old way,
print self.thisown
>>> True
self.thisown = 0
print self.thisown
>>> False
self.thisown = 1
print self.thisown
>>> True
is supported, and python dispatches the proper method
calls as needed.
- Support for iterators in STL/STD containers, for example, if you have
%template<set_string> std::set<std::string>;
you can use the C++ iterators as:
s = set_string()
s.append("c")
s.append("a")
s.append("b")
b = s.begin()
e = s.end()
sum = ""
while (b != e):
sum += b.next()
print sum
>>> "abc"
advance the iterator as in C++
current = s.begin()
current += 1
print current.value()
>>> "b"
now using the reverse operators
b = s.rbegin()
e = s.rend()
sum = ""
while (b != e):
sum += b.next()
print sum
>>> "cba"
or the 'previous' method
b = s.begin()
e = s.end()
sum = ""
while (b != e):
sum += e.previous()
print sum
>>> "cba"
or just as in a python fashion
for i in s:
sum += i
Note 1: Iterators in C++ are very powerful, but
dangerous too. And in python you can shoot yourself in the foot
just like in C++, so, be careful.
Note 2: the iterators are 'light', ie, they do not
convert sequence elements until you request to do so, via
next(), value() or previous(). If you just increment/decrement one
no conversion is performed, for example:
b = s.begin()
b += 1
b.incr()
b.incr(2)
b.decr(2)
b.decr()
b -= 1
only the iterator is modified, and not value wrapper
is generated. Other typical C++ operations are also
available, such as:
print s.end() - s.begin()
>>> 3
f = s.begin() + 1
print f.value()
>>> "b"
l = s.end() - 1
print l.value()
>>> "c"
etc. Of course, the 'find', 'insert', 'erase', and
so on methods also supports iterators now, ie:
i = s.begin()
i += 1
s.erase(i)
for i in s:
sum += i
print sum
>>> "ac"
*** POTENTIAL INCOMPATIBILITY ***
There is no more 'thisown' attribute. If you use it, python
will translate the following code as follows:
if (self.thisown): ==> if (self.this.own()):
self.thisown = 1 ==> self.this.own(1)
self.thisown = 0 ==> self.this.own(0)
Still, maybe in some unusual cases the translation will not be
100% correct, so if you have a problem, please report it
and/or use the new 'self.this.own()' accessor.
*** POTENTIAL INCOMPATIBILITY ***
There is no more ClassPtr classes in the python code. Hence,
if in the past you needed to resort to some kind of trickery
with them, or overcome their presence, it is no longer
required, but the extra code you added could now break
things.
If needed, you can use the option -classptr, i.e.,
swig -classptr -python ...
to generate the old ClassPtr classes.

[Guile] Make declared and defined linkage of SWIG_init consistent.
Reported by Steven G. Johnson (SF patch 1315498).
10/26/2005: mmatus
- Added the attribute.i file to the global library director.
Now it can be used from other languages that do not use
the unified typemap library as well.
So, if you have something like:
%include attribute.i
%attribute(A, int, a, get_a, set_a);
struct A
{
int get_a() const;
void set_a(int aa);
};
%attribute_ref(B, int, c);
struct B
{
int& c();
};
then in the target language the 'A.a' and 'B.c' attributes will
be visible, ie, you can access them as plain variables:
f = A()
f.a = 3
g = B()
g.c = 3
h = f.a + g.c
and the proper get/set methods will be dispatched. See
attribute.i for more info.
- More cleanups around and adding more test-cases. The
DISOWN typemap now is tested and working in all the
languages that use the unified typemap library, ie, tcl,
ruby, perl and python.
10/25/2005: mmatus
- Perl, complete the DISOWN typemap.
- added the attribute.i file to the unified typemap
library (before was only usable from python).
- unify the names for the setter and getter methods in
perl,tcl,ruby and python, so, the attribute.i library
can work across them.
- see the li_attribute.i test-case or the library file
Lib/typemaps/attribute.swg
for more info about how to use it.
10/24/2005: mmatus
- Perl now uses the unified typemap library.
- Changes in ruby to use the $track option in typemaps.
- Changes in the unified typemap library to follow the
convention that all macros that are not used in the
C/C++ side starts with %, such as
%delete
%new_array
etc.
- Documenting fragments, see fragments.swg.
- Cleaner way to use the unified typemap library, include
just <typemaps/swigtypes.swg>.
Check some of the supported languages: perl, tcl, ruby,
python.
Always start with the head file, such as
python/python.swg
tcl/tcl8.swg
ruby/ruby.swg
perl5/perl5.swg
and the principal file that invokes the unified library, such as
python/pytypemaps.swg
tcl/tcltypemaps.swg
ruby/rubytypemaps.swg
perl/perltypemaps.swg
The file that provide the specialization for each
language are the one that provides the basic types:
python/pyprimtypes.swg
ruby/rubyprimtypes.swg
tcl/tclprimtypes.swg
perl5/perlprimtypes.swg
and the string manipulation:
python/pystrings.swg
ruby/rubystrings.swg
tcl/tclstrings.swg
perl5/perlstrings.swg
The rest of the files, such as carray.i, are mostly one
line files that include the proper typemap library
version.

newly added Allegro Common Lisp section in lisp.html
10/20/2005: mmatus
Ruby, Tcl, Python:
- Uniform way to fail (label fail:), now finally
SWIG_exception works across the three languages and all
the typemaps.
- Add proper cleanup code to ruby
- More valgrind fixes
- Simplify the inline use, it seems a small interface of
20,000 lines (plus many many templates) can break
gcc -O3 easily.
- Finalize the typemaps library. All the old *.i files
(carray.i, cpointer.i, exception.i) had been implemented
in the new typemaps library.
10/19/2005: wuzzeb
Update the Runtime Typemap documentation in Typemaps.html
10/18/2005: wuzzeb
Chicken:
- Correctly handle %ignored classes
- Correctly convert long, long long, unsigned long, etc
to chicken primitives. (Thanks to Felix Winkelmann)
- Using argout parameters when the return value was a
wrapped pointer caused a memory corruption. The chicken
garbage collector moved a pointer out from under us.
This is now fixed by running all the proxy creation
functions as continuations after the wrapper function
returns. As part of this, we no longer need the
chickenfastproxy flag on output typemaps.
- using -proxy and -nocollection together works now
Before, it was not exporting the destructor in the proxy
wrapper.
10/18/2005: mmatus
Added the Unified Typemap Library (UTL). It unifies the typemaps for
python, ruby, tcl
and in the process, fixes several problems in each of the three
languages to work in a "canonical" way now established in
the typemap library
SWIG/Lib/typempas
The current status of the unification is that everything
compiles and runs inside the test-suite and examples
directories. And for the first time we have three
languages than pass the primitive_types.i case.
Also, we have a uniform way to treat the errors, for example
if you do something like
>>> from primitive_types import *
>>> print val_uchar(10)
10
>>> print val_uchar(1000)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
OverflowError: in argument 1 of type 'unsigned char'
you get the same exception in all the three languages.
And well, many more good things will come from this
unification, for example, proper support of the STL/STD classes
for all the languages, and hopefully, we can keep
adding other languages.
The hardest part, writing a common typemap library
that suites the three different languages, is done,
and adding another language should now be easy.
Still the global unification is not complete, the STL/STD
part is next, and probably as well as adding one or two more
languages.
If you are curious, look at the python, ruby and/or tcl
directories to see what is needed to support the new
common typemaps library. Still, the final way to
integrate a new language could change as we move to
integrate the STD/STL.
*** POTENTIAL INCOMPATIBILITY in Ruby/Tcl ***
Some missing/wrong typemaps could start working properly,
and change the old behavior, specially in ruby and tcl.
Version 1.3.27 (October 15, 2005)
=================================
10/15/2005: wsfulton
[Java] Fix for typesafe enum wrapping so that it is possible to
overload a method with 2 different enum types.
10/15/2005: wsfulton
Fix for %feature("immutable","0") attempting to generate setters
for constants.
Restored %immutable and %makedefault to clear the feature as it
behaved in SWIG-1.3.25 and earlier.
10/14/2005: mmatus
Fix bug in anonymous typedef structures which was leading to
strange behaviour.
10/13/2005: mmatus
Several minor changes:
- Improve the wchar_t type support
- Add a warning for when you define the 'in' typemap but
you don't define the 'typecheck' one. Very common mistake.
- Add proper default rule for function pointers, now you
can define a typemap such as:
%typemap(in) SWIGTYPE ((*)(ANY)) {...}
That will apply to all the pointer to functions. The
rule in C++ also apply to the function 'reference', ie,
in both cases
typedef int (*fptr)(int a);
typedef int (func)(int a);
This was needed since it seems to be 'illegal' in C++ to
do something like:
void *ptr = static_cast<void *>(fptr);
and probably, as for member functions, it is not
warrantied that the pointer sizes will match.
- Add the #error/#warning directives to swig's cpp.
- Add the noblock option for typemaps, which is used as
follows: supposed you a typemap, like this
%typemap(in,noblock=1) Hello {
....
}
then the typemap will be inserted without the block
imposed by the brackets, similar to
%typemap(in) Hello "..."
So, why you don't just use the quote style?, because:
1.- The quote style doesn't get preprocessed, for example
%typemap(in) Hello "$1= SWIG_macro($1);"
here, SWIG_macro doesn't get expanded
2.- Inside a quote typemap, you have to use
quotes carefully
%typemap(in) Hello "$1 = \"hello\" "
3.- You can't make emacs and/or other editors
to indent inside a string!.
So, why do you want to remove the block?, because an extra
block when not needed (no local variables in it):
1.- makes the code harder to read
2.- makes the code larger
3.- or in short, for the same reason we have the quote style.
Version 1.3.26 (October 9, 2005)
================================
10/08/2005: wsfulton
[Php] Added 'throws' typemaps.
10/08/2005: wsfulton
Fixes for languages that don't support multiple inheritance. The
first non-ignored class in the public base class list is used for inheritance.
by the proxy class. Previously, if the first class in the list was ignored, then
the proxy class wouldn't have any base classes.
10/07/2005: mmatus
Update more features to follow new convention, including:
callback
ref/unref
except
All of them use not only the feature as a flag, but also
as code value. To deal with those features, we use now
GetFlagAttr, which is similar to GetFlag, but instead or
returning 1 or 0, it returns the attr value, if happens
to be different of "0" of course.
Now there are also more uniform directive names for the
ones based in features, for example, for the old
%newobject directive now we have tree directives defined:
#define %newobject %feature("new")
#define %nonewobject %feature("new","0")
#define %clearnewobject %feature("new","")
and so on for all the other feature directives.
*** POTENTIAL INCOMPATIBILITY ***
09/30/2005: wsfulton
Subtle change to some features. Previously it was not possible to disable many
features once they had been enabled. This was for most features that behave as
flags. These features now work as follows:
%feature("name") // enables the feature
%feature("name", "1") // enables the feature
%feature("name", "0") // disables the feature
%feature("name", "") // clears the feature
In fact any non-empty value other than "0" will enable the feature (like C boolean logic).
Previously "1", "0" or any other non-empty value would enable the feature and it would
only be possible to disable the feature by clearing it (assuming there was no global enable).
The following features are affected:
allowexcept
compactdefaultargs
classic (Python)
cs:const (C#)
director
exceptionclass (Python)
ignore
immutable
java:const (Java)
java:downcast (Java)
kwargs
modern (Python)
new
noautodoc (Python)
nodefault
nodirector
noref
notabstract
nounref
novaluewrapper
python:maybecall (Python)
python:nondynamic (Python)
modula3:multiretval (Modula3)
predicate (Ruby)
trackobjects (Ruby)
valuewrapper
It is now possible, for example to ignore all methods/classes in a header file, except for a
few targetted methods, for example:
%feature("ignore"); // ignore all methods/classes
%feature("ignore","0") some_function(int, double); // do not ignore this function
%feature("ignore","0") SomeClass; // do not ignore this Class
%feature("ignore","0") SomeClass::method; // do not ignore this method
%include "bigheader.h"
Removed %pythondynamic - it never worked properly. Use %pythonnondynamic instead.
Removed %feature("nokwargs") - it wasn't fully implemented - use %feature("kwargs","0") instead.

Adding the module option to the %import directive. Now you
can use it as
%import(module="BigModule") foo.i
where subfile could (or not) define the module name via
the %module directive. The module option take precedence
and it has the same effects than having the directive
%module BigModule
inside the imported file foo.i.
You can use the option in mainly two cases:
1.- You used the -module option when you generated the
module to be imported, and hence the module name in
the imported %module directive is not really useful.
2.- The module you want to import is very large, and it
has several .i/.h files. Then, if you just one to
import a class or so from the module, says 'foo', and
not the entire module via importing the main
BigModule.i file, then you just do:
%import(module="BigModule") foo.h
or
%import(module="BigModule") foo.i
where foo.i contains the 'foo' declaration and maybe a
couple of extra %include directives, as needed.

Modifications to STL wrappers so that it is possible for a user's %exception directive
to be applied to the STL wrapper methods. Previously the following global %exception
directive would not be used on the wrapper methods:
%exception {
try {
$action
} catch (...) {
// handle uncaught exceptions
}
}
This has been implemented by replacing %exception directives for specific STL wrapper
methods with an exception specification declared on the wrapper methods. throws typemaps
are now supplied for handling the STL exception specification. These can also be easily
overridden, for example the std::out_of_range exception, which is used a lot in the STL
wrappers, can be customised easily:
%include "std_vector.i"
%typemap(throws) std::out_of_range {
// custom exception handler
}
%template(VectInt) std::vector<int>;
07/22/2005: efuzzyone
[CLISP] The clisp module for SWIG:
- It can only handle C, clisp currently does not supports ffi bindings to C++.
- It has two options, (a) -extern-all this will generate wrappers for all functions
and variablestions, (b) -generate-typedef this will generate wrappers "def-c-type"
wrappers for typedefs
- Can handle pointers to functions, complex types such as n-dimensional arrays of
pointers of depth d
- Generates wrappers for constants as well as variables
- Correctly distinguishes between the declaration of variables in structures and functions
- Creates a defpackage "declaration" with the module name as the package name, the created
package exports both functions and variables
- tries to guess when should a pointer variable be declared as c-ptr or c-pointer
07/22/2005: wsfulton
[C#] Changes to support C# structs returned by value. The changes required are:
- Using an optional 'null' attribute in the out typemap. If this attribute is specified,
then it is used for the $null special variable substitution.
- The ctype used in the C/C++ wrappers is no longer initialised to 0 on declaration.
Both of these changes fix the situations where an attempt was made to assign 0 to the
returned struct. Marshalling structs as value types still requires user defined typemaps.
See documentation for an example.
07/22/2005: wsfulton
[C#, Java] Fix SWIG_exception usage to work with compilers that don't support empty macro
arguments. Unfortunately this fix will stop usage of SWIG_exception being used within typemaps
that use "" or %{ %} delimiters, but continues to work with typemaps using {} delimiters.
Please use the SWIG_CSharpSetPendingExceptionArgument or SWIG_JavaThrowException methods instead
as SWIG_exception is really intended as a platform independent macro for the SWIG library writers.
07/16/2005: mkoeppe
[Allegro CL] Use specific foreign types rather than (* :void).
Use *swig-identifier-converter*.
06/27/2005: wsfulton
Functions declared as 'extern' no longer have an additional function declaration added to the
wrapper files. There are some cases where SWIG does not get this right, eg bug #1205859 (extern
functions with default arguments declared in a namespace). Also SWIG cannot get non-standard
calling conventions correct, eg Windows calling conventions are usually handled like this:
%{
#define DLLIMPORT __declspec(dllimport)
#define STDCALL __stdcall
%}
#define DLLIMPORT
#define STDCALL
%inline %{
DLLIMPORT extern STDCALL void function(int);
%}
SWIG incorrectly generates:
extern void function(int);
To which there is no solution as SWIG doesn't handle non-standard calling conventions. The extra
'extern' function that SWIG generates is superfluous unless a user has forgotten to add the function
declaration into the wrappers.
The -noextern commandline argument is now redundant and a new commandline argument -addextern can
be used to obtain the original behaviour. This shouldn't be necessary unless the header file
containing the function declaration was inadvertently not added to the wrappers. To fix this
add the function declaration into your wrappers, For example, replace:
extern void foo(int);
with:
%inline %{
extern void foo(int);
%}
*** POTENTIAL INCOMPATIBILITY ***
06/22/2005: wsfulton
[C#, Java, Modula3, Ocaml]
The intermediary function names have been changed when wrapping variables to
match the other language modules so that %extend for a member variable works
uniformly across all language modules, eg:
%extend ExtendMe {
Var;
};
%{
void ExtendMe_Var_set(ExtendMe *, double) {...}
double ExtendMe_Var_get(ExtendMe *) {...}
%}
The methods implementing the get/set used to be:
%{
void set_ExtendMe_Var(ExtendMe *, double) {...}
double get_ExtendMe_Var(ExtendMe *) {...}
%}
This also changes the name of variable wrapper functions when using -noproxy.
The original names can be generated with the -oldvarnames commandline option.

they couldn't be removed even when overriding CFLAGS and CXXFLAGS with configure
(./configure CFLAGS= CXXFLAGS=). To turn the maximum warnings off, run:
./configure --without-maximum-compile-warnings
04/28/2005: wsfulton
Patch from Scott Michel which reworks the Java constructor and finalize/destructor typemaps,
for directors to reduce the number of overall Java typemaps. Added the director_take and
director_release typemaps to emulate other modules' __disown__ functionality.
*** POTENTIAL INCOMPATIBILITY FOR JAVA DIRECTORS ***
04/28/2005: wsfulton
[C#] Fixed problems due to the over eager garbage collector. Occasionally the
garbage collector would collect a C# proxy class instance while it was being used
in unmanaged code if the object was passed as a parameter to a wrapped function.
Needless to say this caused havoc as the C# proxy class calls the C++ destructor
when it is collected. Proxy classes and type wrapper classes now use a HandleRef,
which holds an IntPtr, instead of a plain IntPtr to marshal the C++ pointer to unmanaged
code. There doesn't appear to be any performance degradation as a result of this
modification.
The changes are in the proxy and type wrapper classes. The swigCPtr is now of type HandleRef
instead of IntPtr and consequently the getCPtr method return type has also changed. The net
effect is that any custom written typemaps might have to be modified to suite. Affected users
should note that the implementation uses the new 'out' attribute in the imtype typemap as the
input type is now a HandleRef and the output type is still an IntPtr.
*** POTENTIAL INCOMPATIBILITY FOR C# MODULE ***
04/28/2005: wsfulton
[C#] Support for asymmetric type marshalling added. Sometimes the output type needs to be
different to the input type. Support for this comes in the form of a new optional 'out'
attribute for the ctype, imtype and cstype typemaps. If this typemap attribute is not
specified, then the type used for both input and output is the type specified in the
typemap, as has always previously been the case. If this typemap attribute is specified,
then the type specified in the attribute is used for output types and the type specified
in the typemap itself is used for the input type. An output type is a return value from
a wrapped method or wrapped constant and an input type is a parameter in a wrapped method.
An example shows that char * could be marshalled in different ways,
%typemap(imtype, out="IntPtr") char * "string"
char * function(char *);
The output type is thus IntPtr and the input type is string. The resulting intermediary C# code is:
public static extern IntPtr function(string jarg1);

[Guile] Fix generation of "define-method" for methods of
classes with a constructor. Reported by Luigi Ballabio.

[Chicken]
For wrapped functions that return multiple values (using argout),
SWIG CHICKEN now returns them as multiple values instead of as
a list. They can then be accessed using (call-with-values).
04/14/2005: wuzzeb (John Lenz)
[Chicken]
+ Added a whole bunch of new _runme scripts into the chicken test
suite. Also fix some bugs these new scripts turned up.
+ Added optimization when returning a wrapped proxy class. Before,
a minor garbage collection was invoked every time a function returned.
+ All the chicken Examples should now run correctly
04/14/2005: wsfulton
[C#] More fixes for typemap matching when wrapping variables, in particular
std::string, so that std::string variables can be easily marshalled with
a C# string property using:
%include "std_string.i"
%apply const std::string & { std::string *variable_name };
std::string variable_name;
(Recall that all class variables are wrapped using pointers)
04/05/2005: wuzzeb (John Lenz)
[Chicken]
+ Added Examples/chicken/egg, an example on how to build a chicken
extension library in the form of an egg. Also updated the
documentation on the different linking options.
+ chicken test-suite now has support to check SWIG with the -proxy
argument if there exists a _proxy_runme.ss file.
+ More fixes for overloaded functions and -proxy
03/31/2005: wsfulton
Turned on extra template features for all languages which were
previously only available to Python.
This enables typemaps defined within a templated class to be used as
expected. Requires %template on the templated class, %template() will
also pick up the typemaps. Example:
template <typename T> struct Foo {
...
%typemap(in) Foo "in typemap for Foo<T> "
or
%typemap(in) Foo<T> "in typemap for Foo<T> "
};
%template(Foo_i) Foo<int>;
%template() Foo<double>;
will generate the proper 'in' typemaps wherever Foo<int> and Foo<double>
are used.
03/30/2005: mkoeppe (Matthias Koeppe)
[MzScheme] Patch from Hans Oesterholt for supporting MzScheme 30x.
03/29/2005: wuzzeb (John Lenz)
[Chicken]
+ Reallow older versions of chicken (1.40 to 1.89) by passing -nocollection
argument to SWIG
+ %import now works correctly with tinyclos. (declare (uses ...)) will be
exported correctly.
+ TinyCLOS proxy classes now work correctly with overloaded functions
and constructors.
03/29/2005: wsfulton
[Java] Patch from Scott Michel for directorout typemaps. Java directors
require the directorout typemaps like the other languages now. The new
typemaps provide fixes for methods where the return type is returned
by reference (this cannot automatically be made thread safe though).
03/22/2005: wsfulton
Enum casting fixes. Visual C++ didn't like the C type casting SWIG produced
when wrapping C++ enum references, as reported by Admire Kandawasvika.
03/21/2005: wsfulton
[Perl] SF #1124490. Fix Perl macro clashes when using Visual Studio's STL string,
so now projects can #include <string>.
03/21/2005: wsfulton
Fixed %varargs which got broken with the recent default argument changes.
Also works for Java and C# for the first time now.
03/17/2005: wuzzeb (John Lenz)
[Chicken]
+ Fix a whole bunch of bugs in the chicken module. The entire
test suite now compiles, with the exception of the tests that require
std_vector.i, std_deque.i, and so on, which chicken does not have yet.
+ Add support for %exception and %typemap(exceptions). Exceptions are
thrown with a call to (abort) and can be handled by (handle-exceptions)
03/15/2005: wsfulton
[Java] Patch from Scott Michel for directors. Modifications to the typemaps
giving users fine control over memory ownership and lifetime of director classes.
Director classes no longer live forever by default as they are now collectable
by the GC.
03/15/2005: wuzzeb (John Lenz)
[Chicken] Add support for adding finalizers garbage collected objects.
Functions that return new objects should be marked with %newobject and
input arguments which consume (or take ownership) of a pointer should
be marked with the DISOWN typemap.
Also add support for correctly checking the number of arguments passed
to a function, and raising an error if the wrong number are passed.
03/14/2005: wuzzeb (John Lenz)
Add --without-alllang option to configure.in, which is the same as
passing all the --without-python --without-perl5 etc... that Matthias added.
03/09/2005: wsfulton
[Php] Memory leak fix for functions returning classes/structs by value.
03/08/2005: wsfulton
[Perl] Fix for Perl incorrectly taking memory ownership for return types that
are typedefs to a struct/class pointer. Reported by Josh Cherry.
03/07/2005: wsfulton
[C#] Various exception changes for the std::vector wrappers. These now more
accurately mirror the same exceptions that System.Collections.ArrayList throw.
03/07/2005: wsfulton
[C#] Fix undefined behaviour after any of the std::vector methods
throw an exception.
03/07/2005: wsfulton
[C#] When null is passed for a C++ reference or value parameter, the
exception thrown has been corrected to an ArgumentNullException instead
of NullReferenceException as recommended in the .NET Framework documentation.
The default throws typemaps turn a C++ exception into an ApplicationException,
not a SystemException now.
03/07/2005: wsfulton
[C#] Numerous changes in C# exception handling have been made over the past
few weeks. A summary follows:
The way in which C++ exceptions are mapped to C# exceptions is quite different.
The change is to fix C# exceptions so that the C++ exception stack is correctly
unwound as previously C++ exceptions were being thrown across the C PInvoke layer
into the managed world.
New typemap attributes (canthrow and excode) have been introduced to control the
mapping of C++ to C# exceptions. Essentially a callback into the unmanaged world
is made to set a pending exception. The exception to throw is stored in thread local
storage (so the approach is thread-safe). The typemaps are expected to return
from unmanaged code as soon as the pending exception is set. Any pending exceptions
are checked for and thrown once managed code starts executing. There should
be minimal impact on execution speed during normal behaviour. Full details will be
documented in CSharp.html.
The SWIG_CSharpThrowException() function has been removed and replaced with the
SWIG_CSharpSetPendingExceptionArgument() and SWIG_CSharpSetPendingException()
functions. The original name has been deliberately changed to break old code as
the old approach was somewhat flawed. Any user defined exceptions that follow the
same pattern as the old approach should also be fixed.
Numerous new .NET framework exceptions are now available for easy throwing from
unmanaged code. The complete list is:
ApplicationException, ArithmeticException, DivideByZeroException,
IndexOutOfRangeException, InvalidOperationException, IOException,
NullReferenceException, OutOfMemoryException, OverflowException,
SystemException, ArgumentException, ArgumentNullException and
ArgumentOutOfRangeException.

05/05/2005: mmatus
Fix several memory leaks around. Even when we survive knowning
swig is a memory leak factory, it was a little out of
control. To run std_containers.i in the python test-suite,
swig was using ~260MB, now it uses 'only' ~40MB, which is
the same ammount that g++ uses, so, is not that bad.
In the process, I found a couple of extra Deletes, which
in some cases could trigger seg. faults and/or
DOH/asserts.
[python] Better support for directors + exception. More
verbose errors and added an unexpected exception handler.
[python] Fix memory leak for the
std::vector<std::vector<int> >
case,reported by Bo Peng.
[python] Fix SwigPyObject compare problem reporte by
Cameron Patrick.
[python] Fix several warnings in the generated code
for gnu-gcc, Intel and VC7.1 compilers.
02/25/2005: wuzzeb (John Lenz)
Update documentation to use CSS and <div> instead of <blockquote>
I used a script to convert the docs, and it set all the box classes
to be "code". There are actually 4 different classes,
"shell", "code", "targetlang", and "diagram". We need to go through
and convert the divs depending on what they contain.
02/23/2005: mmatus
[Python] Added option -nortti to disable the use of native
C++ RTTI with directors (dynamic_cast<> is not used).
Add more code for directors to detect and report errors in
the python side.
Extend the use of SWIGINTERN whenever is possible.
Remove template warnings reported by VC7.1.
Remove warnings reported by gcc/g++. Finally you can
compile using
g++ -W -Wall -c mymodule_wrap.cxx
and no spurious errors will be generated in the wrapper
code.
02/23/2005: wuzzeb (John Lenz)
Added -external-runtime argument. This argument is used to dump
out all the code needed for external access to the runtime system,
and it replaces including the files directly. This change adds
two new virtual functions to the Language class, which are used
to find the language specific runtime code. I also updated
all languages that use the runtime to implement these two functions.
02/22/2005: mmatus
Fix %template + private error SF#1099976.
02/21/2005: mmatus
Fix swigrun.swg warnings reported when using "gcc -W -Wall"
(static/inline not used in front of a function
declaration), and add SWIGUNUSED attribute to avoid
unused warnings elsewhere.
Fix unused variable warnings.
[Python] Use new SWIGUNUSED attribute to avoid warnings in
SWIGINTERN methods.
[Python] Fix PyOS_snprintf for python versions < 2.2 (SF #1104919).
[Python] Fix map/multimap to allow empty maps (reported by
Philippe Hetroy).
[Docs] Add some documentation to Python.html and
SWIGPlus.html, including for example the fact that
'friends' are now supported.
02/21/2005: wsfulton
[PHP] Patch from Olly Betts, so that wrappers compile with Zend thread safety enabled.
02/17/2005: wsfulton
Memory leak fix in some of the scripting language modules when using default

[C#, Java] SWIG_exception macro will now return from unmanaged code / native code

- Add DohSortList to DOH
- Improve the runtime type system:
+ Speed. Type loading is now O(n log n) instead of O(N^2), which
for large modules is a huge improvement.
+ A whole bunch of functions in swigrun.swg no longer need the
swig_type_list_handle passed to them. The only one left is
TypeQuery. This also makes runtime.swg a lot smaller.
+ Split up swig_type_info structure into two structures
(swig_type_info and swig_cast_info)
+ Store a pointer to a swig_type_info rather than just the type
name string in the linked list of casts. First off, this makes
the guile module a little faster, and second, the
SWIG_TypeClientData() function is faster too.
+ Add the idea of a module into the type system. Before, all the
types were stored in one huge linked list. Now, another level is
added, and the type system stores a linked list of modules, each
of which stores an array of types associated with it.
+ For more information of how the runtime type system now works,
please see Doc/Manual/typemaps.html and Doc/Devel/runtime.txt
- Update all language modules to use the new type system. The changes
to each language module are minor. All languages are now able to
use runtime.swg for external access to the type system. Before
only python and perl did.
- [guile, mzscheme, ocaml, and php4] These languages opened up the
init function inside the .cxx code, and any code in the .swg files
in the init section was inside this function. This was a problem
for swiginit.swg, which needs to be inserted before the SWIG_init
function is opened. Thus I changed these languages to be like
python or perl, where the init function is declared in the .swg
file.
- [Ruby] Instead of moving the init function to the .swg file, I
added a new section initbeforefunc, and then added
%insert(initbeforefunc) "swiginit.swg"
- [MzScheme] Fix enums and fix Examples/Makefile.in so that if
multiple -I arguments are specified in the INCLUDES variable, each
gets a ++ccf.
- [Guile GH] Update Guile GH to use the new type system. See
Doc/Manual/Guile.html for how smobs are now used.
01/11/2005: wsfulton
[C#] New typemap called 'csconstruct'. The code in this typemaps was previously hard
coded and could not be customised by a user. This typemap contains the code that is
generated into a proxy class's constructor.
[Java] New typemap called 'javaconstruct'. The code in this typemaps was previously hard
coded and could not be customised by a user. This typemap contains the code that is
generated into a proxy class's constructor. Another typemap named 'javaconstruct_director'
is used instead when the proxy class is a director class.
[C#, Java] If a C++ class did not have a default constructor, a protected default constructor
was automatically generated by SWIG. This seems is unnecessary and has been removed
and thereby giving the user almost complete control over the generated code along with the
new typemaps above.
19/12/2004: mmatus
[Disabled, see entry 02/15/2004]
- Fix typemap search, now the "out" typemap search is done as follows
int *Foo::foo(int bar) -> int *Foo::foo(int bar)
-> int *Foo::foo
-> int *foo(int bar)
-> int *foo
-> int *
then, now you can be more specific, and define
/* apply only for 'Foo::foo' method */
%typemap(out) int * Foo::foo(int *bar) ...;
/* apply for all 'foo' functions/methods */
%typemap(out) int * foo(int *bar) ...;
%inline {
struct Foo {
int *foo(int *bar);
};
}

- More fixes for templates and template default args.
See template_default.i for scary cases that now are
supported, besides the already ugly STL/std cases.
- Cosmetics and more use of 'const' where it was implicit.

[Chicken] Fix a bunch of bugs relating to -proxy support
+ non-class variables now export properly using -proxy
+ static member functions now export properly using -proxy
+ member class variables now export properly using -proxy
+ added a -nounit argument, which does not export the (declare (unit ...))
+ correctly install swigclosprefix.scm
+ constants (enums, defines) now correcly export when using -proxy
12/11/2004: wsfulton
configure fix for when more than one version of jni_md.h is found
in the Java include directory (was generating lots of sed error
messages).
12/08/2004: wsfulton
[Java] Fixes to arrays_java.i so that one can apply the array
typemaps to functions taking pointers as input, eg
%include "arrays_java.i"
%apply int[] {int*};
void foo(int *a);
12/05/2004: wsfulton
[Java] Director mods contributed by Scott Michel. New typemaps
directordisconnect and directordisconnect_derived for the
swigDirectorDisconnect() method. Also fix to get the javapackage
typemap working again.
12/05/2004: mmatus
- Finishing the fixes for templates + default template
args + specializations.
- [Python] Now we use the new templates + default template
args in the std/STL library. That means the internal
swig files are getting uglier since we now support the
original declarations:
template<class _Tp, class _Alloc = std::allocator< _Tp > >
class vector {
....
};
template<class _Key, class _Tp, class _Compare = std::less<_Key >,
class _Alloc = std::allocator<std::pair<const _Key, _Tp > > >
class map {
....
};
and the user can use the %template directive as
%template() std::vector<int>;
%template() std::vector<int, std::allocator<int> >;
%template() std::vector<int, MyAllocator<int> >;
Now we are closer to the cleaning/rewriting of the
python std/STL support, such that we recover support for
MSVC++ 6.0, and we can add support for other languages
too.
12/02/2004: wsfulton
[Java] Fix for directors when wrapping methods using a member enum
and typesafe/proper enums enabled.
12/01/2004: mmatus
- Fix typemaps to work with templates and default template
args, ie
template <class A, class B = int>
struct Foo {
};
%typemap(in) Foo<int> *{...}
%typemap(out) Foo<int,int> *{...}
Foo<int> * foo( Foo<int> *f1, Foo<int,int> *f2);
now 'f1', 'f2' and the return value resolve the provided
typemaps properly.
This is highly needed for proper STL support, see new
std_basic_string.i, std_sstream.i, etc.
- Added std_sstream.i, and fix std_basic_string.i to use
the new typemaps + template def. arg mechanism. Also,
added the needed std_alloc.i. Now, all the containers
can be modified to support std::allocator, like in:
template<class T, class A = std::allocator<T > >
class vector {
public:
....
};
This change is only completed by now for basic_string.
- Fix for smart pointers + members + extensions:
%extend Foo {
int extension(int i, int j) { return i; }
int extension() { return 1; }
}
%inline %{
class Foo {
public:
int y;
static const int z;
};
class Bar {
Foo *f;
public:
Bar(Foo *f) : f(f) { }
Foo *operator->() {
return f;
}
};
now you can
f = Foo()
f.y = 3
a = f.z
f->extension()
b = Bar(f)
b.y = 3
a = b.z
b->extension()
- Other small errors fixes, mostly python.
11/25/2004: wsfulton
[Java] Numerous director bug fixes so that the correct java types
and canonicalized types in the JNI code are emitted. Use of the
$javaclassname special variables in the director typemaps now
consistent with the non-director typemaps. The types used for
typemap lookups are also corrected in a few places. If you
previously had your own director typemaps, ensure they are using the
correct C++ type.
*** POTENTIAL INCOMPATIBILITY FOR JAVA DIRECTORS ***
11/25/2004: wsfulton
const enum SWIGTYPE & typemaps added. These wrap const enum references
as if they were passed by value. Const enum references thus work the
same as const reference primitive types such as const double &,
const int & etc. Typemaps added for Java, C#, Ruby, Tcl, Perl and Pike.
11/25/2004: wsfulton
[Java, C#] New special variable: $*javaclassname, similar to $javaclassname
and $&javaclassname. The new one removes a pointer from the C type before
obtaining the Java class name. One or more of $javaclassname,
$&javaclassname or $*javaclassname may now appear in a typemap. Likewise for
C# using csclassname instead of javaclassname.
11/25/2004: wsfulton
The last vestiges of enums being handled as integers removed from the
internals. The wrapper methods use the enum type rather than an int
now. The net result is added type safety for enums when handled as
pointers, references etc. Previously in situations such as a method
taking a pointer to an enum, a pointer to an int or a pointer to an
enum of some other type could inadvertantly be passed to the method.
This is now fixed as the descriptor for an enum is no longer based on
an int, but the enum type instead. Anonymous enums are still handled
as integers.
The consequence for scripting language users in correct usage of enums
should not be noticeable. There is no change for any of the languages
where enums are passed by value - most of the scripting languages will
still accept an integer for an enum value and the strongly typed
languages still use either typesafe enums, integers or proper enums
depending on what the user configures. For Java and C# users a change
in the typewrapper class name has occurred (for enum pointers,
references etc). For example:
enum Numbers { one=1, two };
enum Numbers* number();
In Java and C# this must now be coded as
SWIGTYPE_p_Numbers n = modulename.number();
rather than
SWIGTYPE_p_int n = modulename.number();
*** POTENTIAL INCOMPATIBILITY ***
11/21/2004: wsfulton/mmatus
Added missing deprecated warning for %name and remove remaining %name
usage in the SWIG libraries.
11/21/04: mmatus
- [Python] Adding the PySwigObject to be used for carrying
the instance C/C++ pointers. This is used instead of
string and PyCObjects.
The new PySwigObject is even safer than PyCObject, and
more friendly than plain strings:
now you can do
print a.this
<Swig Object at _00691608_p_A>
print str(a.this)
_00691608_p_A
print long(a.this)
135686400
print "%s 0x%x" % (a.this, a.this)
_00691608_p_A 0x8166900
the last one is very useful when debugging the C/C++
side, since is the pointer value you will usually get
from the debugger.
Also, if you have some old code that uses the string
representation "_00691608_p_A", you can use it now again
using 'str(ptr)', or by calling 'str = PyObject_Str(obj)'
in the C/C++ side.
This change is mainly for nostalgic swig users that miss
the string representation, but also allows to say again
if a.this == b.this:
return "a is b"
and well, since the change were really simple, maybe in
the future we will be able to do
next = a.this + 1
or add native python iteration over native C/C++ arrays,
ie, no need to create/copy new tuples when returning and
array or vector.
Also, a PySwigPacked object was adding to carry a member
method pointer, but this is probably a temporary solution
until a more general object for methods is added.
Be aware that to simplify maintaining and compatibility
with other tools, the old string and PyCObjects
representation could disappear very soon, and the
SWIG_COBJECTS_TYPES or SWIG_NO_OBJECT_TYPES macros will
have no effect at compilation time. Still, the three
mechanisms are present in the code just for testing,
debugging and comparison purposes.
11/21/04: mmatus
- [Python] Adding back support for using the swig runtime code
inside the user code. We just allow the user to include
the minimal code needed to implement the runtime
mechanism statically, just as in done in the swig
modules.
To use the swig runtime code, for example with python,
the user needs include the following:
#include <Python.h> // or using your favorite language
#include <swigrun.swg>
#include <python/pyrun.swg> // or using your favorite language
#include <runtime.swg>
the files swigrun.swg, pyrun.swg and runtime.swg can
be checked out by using swig -co, or they can simply
be found by adding the swig lib directory to the
compiler include directory list, for example
SWIGLIB=`swig -swiglib`
c++ -I${SWIGLIB} ..
of better, using the CPPFLAGS, but that depends on your
environment.
This change can be ported to the other languages too,
you just need to isolate the needed runtime code in
a single file like 'pyrun.swg', and provide the
SWIG_Runtime_GetTypeList() method. Look at the
Lib/python/pyrun.swg file and the Examples/python/swigrun
example.
11/15/04: mmatus
- Fix mixed_types.i + gcc-3.4, ie, arrays + references +
typedefs
- Fix multidim arrays + typedefs,ie
typedef char character[1];
typedef character word[64];
- Process protected/private bases in the same way before
we process protected/private members, ie, we check
for constructors, operator new, virtual members, etc.
- Fix Ruby/Java to work (or ignore) multi-inheritance +
directors. Allow other languages to define if it is
supported or not.
- Now you can run
SWIG_FEATURES="-directors -dirprot"
make check-ruby-test-suite
make check-python-test-suite
make check-java-test-suite
make check-ocaml-test-suite
and you will get only 'real' errors. ruby and python
compile with no errors, java shows some problems.
Version 1.3.23 (November 11, 2004)
==================================
11/05/2004: wsfulton
Patch #982753 from Fabrice Salvaire: Adds dependencies generation for
constructing makefiles. New command line options -MF -MD -MMD to work
with the current options -M and -MM. These options are named the same
and work the same as in gcc.
11/05/2004: wsfulton
%ignore/%rename changes for methods with default arguments to mirror
%feature behaviour. See previous entry.
*** POTENTIAL INCOMPATIBILITY ***
11/04/2004: wsfulton
%feature improvements for fine tuning when wrapping methods with
default arguments. Any %feature targeting a method with default arguments
will apply to all the extra overloaded methods that SWIG generates if the
default arguments are specified in the feature. If the default arguments are
not specified in the feature, then the feature will match that exact
wrapper method only and not the extra overloaded methods that SWIG generates.
For example:
%feature("except") hello(int i=0, double d=0.0);
void hello(int i=0, double d=0.0);
will apply the feature to all three wrapper methods, that is:
void hello(int i, double d);
void hello(int i);
void hello();
If the default arguments are not specified in the feature:
%feature("except") hello(int i, double d);
void hello(int i=0, double d=0.0);
then the feature will only apply to this wrapper method:
void hello(int i, double d);
and not these wrapper methods:
void hello(int i);
void hello();
This has been introduced to make %feature more powerful to ease the migration
to new default arguments wrapping approach.
*** POTENTIAL INCOMPATIBILITY ***
If you previously had a %feature and didn't specify the default arguments,
you will have to add them in now or you can obtain the original behaviour
by using %feature("compactdefaultargs").
11/04/2004: wsfulton
[C#] Typemaps for std::vector added into std_vector.i. The proxy classes
generated are modelled on the .NET ArrayList class. This isn't quite
ready for general consumption yet, but will work with vectors of primitive
types and some classes.
10/3/2004: wuzzeb (John Lenz)
[GUILE] The -scm interface is now the default. The old GH interface can
still be enabled by passing -gh to SWIG.
10/2/2004: mmatus
- More fixes for namespace + class declarations.
As an extra bonus, we get %template support for static/members class
methods, ie, now you can say:
namespace space {
struct A
{
template <class Y>
static void fooT(Y y) { }
};
}
struct B
{
template <class Y>
void barT(Y y) {}
};
%template(foo) space::A::fooT<double>;
%template(foo) space::A::fooT<int>;
%template(foo) space::A::fooT<char>;
%template(bar) B::barT<double>;
%template(bar) B::barT<int>;
%template(bar) B::barT<char>;
and call
A.foo(1)
b = B()
b.bar(1)
note the methods are emitted inside the classes,
and hence, the %template name refers to the 'member'
method name, not a global namespace name.
10/31/2004: mmatus
- Solve namespace + class declarations, as in
namespace foo {
struct Bar;
struct Foo {
};
}
struct foo::Bar : Foo {
};
see namespace_class.i for more examples.
- Fix %template directive to properly use namespaces,
including the case:
namespace one
{
template <typename T>
struct Ptr {};
}
namespace one
{
struct Obj1 {};
typedef Ptr<Obj1> Obj1_ptr;
%template(Obj1_ptr) Ptr<Obj1>;
}
namespace two
{
struct Obj2 {};
typedef one::Ptr<Obj2> Obj2_ptr;
%template(Obj2_ptr) one::Ptr<Obj2>;
}
this is done by using the namespace name 'one' to create
a namespace node to emit the template instantiation,
just as before, but the template parameters are resolved
and qualified in the current namespace ('one' or 'two').
This is same way that typedef works.
This resolve the smart_pointer_namespace2.i case, and at
the same time, several other ones where before swig was
generating the
"Can't instantiate template 'xx' inside namespace 'yy'"
error message. In fact, that error doesn't exist
anymore. You can only get an error if you use a bad
namespace name or so.
10/30/2004: mmatus
- [ruby] Directors fixes:
- enums and std::strings are working now (several
reports in bug track system)
- added patch 1025861 for director + exceptions
*** Attention ***: ruby with directors + protected
members work with version 1.7+. Older versions seems to
have a broken signature for'rb_protect'.
If you need to use an old version, look at
http://excruby.sourceforge.net/docs/html/ruby__hacks_8hpp-source.html
for workarounds.
- [ruby] Fix memory allocation problem in typemap (bug 1037259)
- [tcl] Fix (enums|constants) + namespace option
(reported by jason.m.surprise@intel.com).
- [perl] Add patch 962168 for multiple inheretance
- Fix 'defined' as variable name.
10/29/2004: wsfulton
Seg fault fix for global scope operator used for friend methods:
class B {
friend void ::globalscope();
...
};
10/28/2004:mmatus
- Added module and swig option "templatereduce" to force swig
to reduce any type needed with templates, ie, in these cases
%module("templatereduce") test
template <class T> struct A { };
typedef int Int;
%template(A_Int) A<Int> ==> %template(A_Int) A<int>
typedef B* Bp;
%template(A_Bp) A<Bp> ==> %template(A_Bp) A<B*>
swig reduces the types Int and Bp to their primitives
int and B*. This is closer to the usual compiler
resolution mechanism, and it is really needed sometimes
when you mix templates + typedefs + specializations.
Don't use it if you don't have any problem already,
since the type reduction can interfere with some
user typemaps, specially if you defined something like
typedef int Int;
%typemap(in) Int ...;
in this case, when you use the "templatereduce" option,
swig will ignore the user typemap, since the "typedef int Int"
will take precedence, and the usual "int" typemap will be
applied.
Note that the previous case is not common, and should be
avoided, ie, is not recommended to use a typedef and a
typemap at the same time, specially if you are going to
use templates + specializations.
- Directors:
virtual destructor is always emitted now, this doesn't
cause any harm, and could solve some nasty and
mysterious errors, like the one mentioned by Scott.
also the destructor is not in-lined, so, that can solve
some other mysterious errors when mixing directors +
imports + embedded applications + some specific compilers.
10/27/2004: wsfulton
[C#] typemaps.i library file with INPUT, OUTPUT and INOUT typemaps added.
10/27/2004: wsfulton
[Java] std::wstring typemap fixes in std_string.i from Russell Keith-Magee.
10/25/2004: mmatus
- Using + namespace is working now (using_namespace.i).
- Derived + nested classes is working now
(deriver_nested.i), but of course, we are still waiting
for the nested class support.
- Directors:
- unnamed parameters support,
- protected constructor support (automatic and with
dirprot mode),
- detection of really needed protected declarations
(members and constructors) now is done automatically.
Even if you don't use the 'dirprot' mode, swig will
wrap what is minimally needed (and protected) for the
code to compile.
what is public, as usual, is always wrapped, and if
you use the 'dirport'
- Final fixes for the OSS to compile with SWIG 1.3.23 (my
very very ugly C++ + templates + everything mounters wrap).
10/25/2004: wsfulton
[C#] New commandline option -dllimport. This enables one to specify
the name of the DLL for the DllImport attribute. Normally this name
comes from the module name, so now it is possible to override this:
swig -csharp -dllimport xyz example.i
will generate for all the wrapped PInvoke methods:
[DllImport("xyz", EntryPoint="...")]
public static extern ...
The wrappers from many different SWIG invocations can thus be compiled
into one DLL.
A new special variable $dllimport can also be used in typemaps, pragmas,
features etc. This will get translated into the value specified by -dllimport
if specified, otherwise the module name.
10/22/2004: wsfulton
[Java] Patch #1049496 from Scott Michel fixes directors methods with
enums when wrapped with typesafe or proper Java enums.
10/21/2004: wsfulton
Fixes for default arguments in director constructors (Python, Ruby, Ocaml).
10/21/2004: mmatus
- [Python] Add the '-cpluscast' option to enable the 'new'
C++ casting operators, such as 'static_cast', inside the
typemaps. By default swig use the old C cast style, even
when parsing C++.
- [Python] Add the '-new_vwm' option to enable the new
SwigValueWrapper mode. Now this is mainly for testing
that the typemaps are really safe for any future
solution, but you can use it if you have a very strange
error with default cosntructors missing + %apply +
%typemap, and if everything else fails (see
valuwrapper_opaque.i for alternative and current
solutions). If you are a user that don't know what is
SwigValueWrapper, don't even try it.
- [Python] Add the '-noh' option to be used with directors
and when you prefer to disable the generation of the
director header file. If not used, swig will work as
usual generating both the wrap.cxx and wrap.h files. If
you use it, swig will only generate wrap.cxx.
10/21/2004: wuzzeb (John Lenz)
- If you define SWIG_TYPE_TABLE when compiling a wrapper file,
the runtime types will be stored in the given type table name.
Using this, you can seperate different modules to share their
own type systems. -DSWIG_TYPE_TABLE=Mytable
- [Python] If you define SWIG_STATIC_RUNTIME then the type information
will be static to this wrapper. Nothing will be shared with any
other modules
- [Python] If you define SWIG_LINK_RUNTIME, then instead of using
the new way of sharing type information, the wrapper will expect
to be linked against the Lib/linkruntime.c file. Any modules compiled
with SWIG_LINK_RUNTIME and linked against linkruntime.c will all
share type information.
10/20/2004: mmatus
- [Python] Initial fix for python/import example. Please
update the Makefile (autoconf, configure, etc, expert),
since now probably is only working with g++, icc and a
few other compilers that have the -shared option.
We need to create additional shared libraries for the
virtual destructors. Old and usually forgotten C++
requirement.
Same fix need to be used in perl, I think.
- [Python] Fix generation of header file for directors,
now directors.swg is also included, so, it can be really
used from C++, and it solves some problem with compiler
that require that, even with the simple swig inclusion.
- [Python] Reordering the methods and moving some bodies
outside the class declaration. This is needed due to
some gcc-2.96 internal compiler errors. It seems the
PYTHON class is getting too large to been declared and
defined at the same time.
- Add the -oh option to change the output header file name
if needed:
swig -c++ -python test.i -o test.CC -oh test.HH
this is mainly needed when using directors, and if the
current default header file name is not good for you,
which is generated as follow:
swig -c++ -python test.i => test_wrap.h
swig -c++ -python test.i -o test.CC => test.h
10/20/2004: wsfulton
1) Compact default arguments feature added. This feature allows one
to use the default argument code generation that was used in
SWIG-1.3.22 and earlier versions. It produces more compact wrappers
as only one wrapper method is generated for any method with default
arguments. So the advantage is it generates less code but has the
original limitations, like it it does not work with all default arguments
and default arguments cannot be taken advantage of in the strongly typed
languages (C# and Java). It is implemented via the usual %feature mechanism:
%feature("compactdefaultargs");
2) Keyword arguments (kwargs) are working again for default arguments
in the languages that support it, ie, Python and Ruby. The new default
argument wrapping approach using overloaded methods cannot support kwargs
so the compact default argument feature is automatically turned on when
kwargs are specified, by %feature("kwargs").
3) Compact default arguments are also automatically turned on when wrapping
C (not C++) code. This is to support the bizarre notion of default arguments
for C code.
10/20/2004: wsfulton
Overloaded templated functions in namespaces also working now.
Templated functions with default arguments in namespaces too.
10/19/2004: mmatus
- Allow to disable the new SwigValueWrapper mechanism,
if you add the following line in your language main.
/* Turn on safe value wrapper use mode */
Swig_value_wrapper_mode(1);
Now is only active in python. All the other languages
are using the old resolution, but they can also use the
"valuewrapper"/"novaluewrapper" features to fix some
of the old broken cases. Note, however, that not all
the broken cases can be solved in that way.
The new mechanism seems to be working fine in perl, ruby
and tcl, but failing in some typemaps in java.
Hence, is upto the language maintainer to test it, and
decide to enable it or not.
Look at the valuewrapper_opaque.i for examples.
- Fix more SwigValueWrapper cases when the new mechanism
is active. Now it also check for local typemap
variables, see valuewrapper_opaque.i for an example when
this is needed. But again, this extra checking will only
be activated when using the new value wrapper mode.
- [Python] Fix variable wrapping of classes with private
assign operators. It should be easy to fix in all the
other modules, instead of checking
if (!Getattr(n,"immutable")) ...
you need to verify
if (is_assignable(n)) ...
Look at the private_assign.i for an example.
10/18/2004: mmatus
- %features "director"/"nodirector" now work as expected.
- General fixes in %feature to resolve function decl
properly,
%feature("hello") foo();
char foo() -> f() // was working
char *foo() -> f().p // it wasn't
- Template + specialization + default template args now is
working, (don't confuse with template + default arg
values, that was solved before), now this ugly case is
working:
template <class T, class A = Alloc<T> >
struct Vector
{
Vector(T a){}
};
template <>
struct Vector<double>
{
Vector(){}
int foo() { return 0; }
};
%template(V_c) Vector<char, Alloc<char> >;
%template(V_i) Vector<int>; // picks Vector<int,Alloc<int> >
%template(V_d) Vector<double>; // picks the specialization
this is needed for automatic STL support (later will
be).
- Fix the template + typedef errors in test-suite, which
probably will fix another group of strange template +
namespaces + typedefs errors.
- %warnfilter is working better now, parser.y tries to use
them when needed.
- **** New default type resolution method (stype.c) *****
It preserves the original mixed types, then it goes
'backward' first deleting the qualifier, then the inner
types, for example:
typedef A *Aptr;
const Aptr&;
r.q(const).Aptr -> r.q(const).p.SWIGTYPE
r.q(const).p.SWIGTYPE -> r.p.SWIGTYPE
r.p.SWIGTYPE -> r.SWIGTYPE
r.SWIGTYPE -> SWIGTYPE
enum Hello {};
const Hello& hi;
r.q(const).Hello -> r.q(const).enum SWIGTYPE
r.q(const).enum SWIGTYPE -> r.enum SWIGTYPE
r.enum SWIGTYPE -> r.SWIGTYPE
r.SWIGTYPE -> SWIGTYPE
int a[2][4];
a(2).a(4).int -> a(ANY).a(ANY).SWIGTYPE
a(ANY).a(ANY).SWIGTYPE -> a(ANY).a().SWIGTYPE
a(ANY).a().SWIGTYPE -> a(ANY).p.SWIGTYPE
a(ANY).p.SWIGTYPE -> a(ANY).SWIGTYPE
a(ANY).SWIGTYPE -> a().SWIGTYPE
a().SWIGTYPE -> p.SWIGTYPE
p.SWIGTYPE -> SWIGTYPE
before it always stops after finding ref/pointer/enum/array/etc.
Now, then, you can define (use and apply) 'higher' typemaps such as:
%typemap(in) SWIGTYPE* const&
%typemap(out) char FIXSIZE[ANY]
%typemap(in) SWIGTYPE* const&
%typemap(in) const enum SWIGTYPE&
%typemap(in) SWIGTYPE[ANY][ANY]
%typemap(in) const char (&)[ANY]
It is possible with this change that previous typemaps
that were defined (but ignored), now will start to work.
Also, it is necessary check for the '%typemap(varin) SWIGTYPE[]',
before it was usually not defined (but char[] was),
and that can produce some inconsistencies.
*** POTENTIAL INCOMPATIBILITY ***
This change was needed for STL, since std::vector<enum Hello>
std::vector<A*>, etc, will always generate methods that
mix const references with the vector type.
Now that is working, all the std::container<T*>
specialization will not be needed anymore, well, in
theory.
In the practice, everythin is working as before until
the proper mixed types are defined and the libraries
simplified to use them.
- Change the behavior of extern "java"/"fortran"/"etc",
now swig produces a warning, and use extern "C" instead.
The warning can also be disable with the "-w 313" flag.
(WARN_PARSE_UNDEFINED_EXTERN).
- SwigValueWrapper is now more selective (lang.cxx).
[Perl/Tcl]
- Fix some typemaps (perl/tcl) to work properly with
SwigValueWrapper. This was not a problem with
SwigValueWrapper, but with the typemaps that now are
safe to use with %apply.
[Python]
- Fix %callback/%pythoncallback work now as before after
the def args changes. Also, %callback now is an alias
for %pythoncallback, so, they do the same.
[Python/Ruby]
- %callback is more usable and uniform:
%callback("%s_cb") foo(); // for both, python/ruby
%callback("%s_cb"); // for both, python/ruby
%callback(1) foo(); // only in python.
10/17/2004: arty
[OCAML]
- Tweak to enum typing for soundness in the presence of multiple
modules.
- global functions are now unambiguous in multiple loaded modules.
- Fixed test case code to build multimodule test cases correctly.
- There is no way to share overload resolution across modules
because of soundness issues. If the user wants to call some
function foo from an arbitrary module bar, they will have to
use Bar._foo to call it correctly. Later I will fix the
camlp4 module to do something clever in this case.
- Promided performance overhaul of class mechanism.
- Removed symbol hack for ocaml-3.07 and below which is not needed
for ocaml-3.08 and above.
10/16/2004: wuzzeb (John Lenz)
[CHICKEN]
- Completly change how chicken.cxx handles CLOS and generic code.
chicken no longer exports -clos.scm and -generic.scm. The clos
code is exported directly into the module.scm file if -proxy is passed.
- The code now always exports a unit. Running the test-suite is now
majorly broken, and needs to be fixed.
- CLOS now generates virtual slots for member variables similar to how
GOOPS support works in the guile module.
- chicken no longer prefixes symbols by the module name, and no longer
forces all names to lower case. It now has -useclassprefix and -closprefix
similar to how guile handles GOOPS names.
10/16/2004: wsfulton
Templated functions with default arguments working with new default argument
wrapping approach. The new approach no longer fails with the following default
argument pattern (previously failed with some primitive types, like
unsigned primitive types):
template<typename T> int foo(const T& u = T());
%template(foo) foo<unsigned int>;
This relies on the templated function overloading support just added, so all
the combinations of overloading by template parameters and normal parameters
as well as overloading with default parameters works.
10/16/2004: wsfulton
Added support for the large range of templated function overloading that C++
supports.
- Overloaded templated functions, eg
template<typename T> int overload(T t);
template<typename T> int overload(T t, const T &r);
- Fixes where the templated type is not used in the parameter list, eg
template<typename T> void xyz();
template<> void xyz<double>();
- Fixes for overloading of plain functions by a templated function:
void abc(double d);
template<typename T> void abc(T t);
- Overloading by templated parameters fixed:
template<typename T> void foo(T t) {}
template<typename T, typename U> void foo(T t, U u) {}
%template(foo) foo<double, double>;
- All combinations of the above also working including specializations, eg:
void abc(double d);
template<typename T> void abc(T t);
template<> void abc<double>(double t);
template<> void abc(int t);
10/16/2004: wuzzeb (John Lenz)
- Remove the ability to share type information by using c linking.
All type sharing happens through a global variable in the target language.
+ Remove SWIG_NOIMPORT, SWIG_RUNTIME, and related defines.
+ Deprecate -runtime, -noruntime command line options
+ Update test-suite common.mk to correctly build multicpptest
+ Remove reference to precommon.swg
+ Update the guile_gh interface to share data by a global var instead
of c linkage.
- Remove Advanced.html, since everything in it is now obsolete
10/09/2004: mmatus
- Split the python std/STL C++ library files, now
all the language independent definitions are under
the directory
Lib/std
and hence, can be used from other languages.
- Add more documentation to the Python STL, and
clean unnecessary code.
- Add initial C99 complex support, and some fixes
for long double.
10/08/2004: mmatus
- Fix the SwigValueWrapper for opaque types, now it is
applied for opaque templates and classes, for which we
don't know if there is or not a default constructor, ie
struct A {
A(int);
};
Still, if you know that you class has a default
constructor, and for some very very particular reason
you want to avoid the SwigValueWrapper, and you don't
want or can't expose the class to swig, now you can
say
%feature("novaluewrapper") A;
class A;
or the other way around, if the class has a default
constructor, but you want to use the value wrapper, you
can say
%feature("valuewrapper") A;
struct A {
A();
....
};
- Fix for char > 128, ie
const char tilde_a = '\341';
- Add patch 1041858 for $lextype, which carries the
literal type of a symbol. See lextype.i in the
test-suite for more details.
10/07/2004: wsfulton
{Ruby, Java] Fix director + 'empty' throws
struct A {
A() throw();
virtual ~A() throw();
int foo() throw();
};
10/06/2004: wuzzeb (John Lenz)
[TCL]
- Fix bug reported by William A. Hoffman propagating clientdata
between modules. Added clientdata_prop.multicpptest to check for
this bug. The fix involved the following changes:
+ SwigType_clientdata_collect does not need to check
types in r_resolved because we only want to propagate clientdata
to typedefed classes, and r_mangled already takes care of typedefs.
+ SWIG_TypeRegister now copies the clientdata field correctly
+ Move SWIG_Guile_PropagateClientData function from guile module
into common.swg, because we need to call it from both guile and tcl.
+ Add base_names to swig_class to delay the lookup of bases. SWIG
now exports the base names and only when the base swig_class is
needed is SWIG_TypeQuery(name)->clientdata looked up.
- conversion_ns_template testsuite test was failing because
the name of the wrapped constructor function was not calculated
correctly for structs. Fixed.
10/06/2004: wsfulton
Fixes for default arguments used in directors - in virtual
methods and director constructors.
10/06/2004: mmatus
Fix the __cplusplus macro, and bug 1041170.
Now it is working as supposed, ie, you can safely use
#ifdef __cplusplus
...
all over swig, including inside %defines and %{ %} bodies.
*** POTENTIAL INCOMPATIBILITY ***
The old trick of using
#if __cplusplus
doesn't work any more. So, if you have your own typemaps
using that syntax, you will need to migrate them to use
"#ifdef __cplusplus".
10/05/2004: wuzzeb (John Lenz)
- Reorganize how runtime type information is stored and shared
between modules. For chicken and mzscheme, I removed
the ability to use runtime libraries, while perl, tcl, python, and
ruby default to using the new method but can go back to the old
method by declaring SWIG_ALLOW_RUNTIME.
- line 582 in mzscheme.cxx was generating a segfault on
imports.multicpptest, so I fixed it.
10/05/2004: wsfulton
Fixes for %extend and overloaded static methods with default
arguments.
10/05/2004: mmatus
- [python] Fix director + method with 'empty' throw, ie
struct A {
virtual int foo() throw();
};
other languages should also easy to fix, look for
Getattr(n,"throw") in python.cxx.
- Fix director + destructor with 'empty' throw
struct A {
virtual ~A() throw();
};
- Now SWIG_FEATURES parse all and the same options you
can pass to swig in the command line.
- New command line flag: -features <list>, as in
swig -features autodoc=3,director
ie, any global feature can be initialized from the
command line. This is mainly for testing, but users
can also take advantage of it.
10/04/2004: mmatus
- Properly qualify type in syntax as 'long(2)' or 'Foo()',
this solve old problem with default args, and probably
other problems around. However, the default arg problem
was also already solved by William (see below).
- Fix feature_set and feature_get methods. Before
they look from particular to general and keep the first
feature found. This didn't work well with templates.
Now the methods look from general to particular, and
override any found feature.
- Previously a feature could not be applied to constructors
or destructors that weren't explicitly declared in the class.
This is now fixed, for example:
%feature("featurename") Foo() "..."
%feature("featurename") ~Foo() "..."
class Foo {
// implicit Foo() and ~Foo()
};
- Fix missing features for default const/dest, by really
'creating' the methods and applying the features.
- Fix return_const_value.i case by adding SwigValueWrapper<const T>
specialization.
- Fix %extend + overload, including overloading actual
class methods.
- Adding more cases in related files in the test-suite.
10/04/2004: wsfulton
Changes to the way default arguments are wrapped. Previously a single
method was generated for each method that had default arguments. If
a method had 5 arguments, say, of which 1 had a default argument
then the call to the wrapped method would pass 5 arguments. The default
value was copied into the wrapper method and used if the scripting
language passed just 4 arguments. However, this was flawed as the
default argument sometimes does not have global access, for example
SWIG would generate code that couldn't compile when wrapping:
class Tricky {
public:
void foo(int val = privatevalue);
void bar(int val = Tricky::getDefault());
private:
static int getDefault();
enum { privatevalue = 200 };
};
Also bugs in resolving symbols generated code that wouldn't compile, for example
(probably fixable though):
namespace Space {
class Klass {
};
Klass constructorcall(const Klass& k = Klass());
}
The approach also does not work for statically typed languages (C# and Java)
as these languages do not allow methods to have variable number of arguments.
Although C# has a mechanism to pass a variable number of arguments they
must be of the same type and are more like varargs.
The new approach solves the above problems and wraps methods with default
arguments as if the method was overloaded. So SWIG will now treat
void foo(int val=0);
as if it had parsed:
void foo(int);
void foo();
The code generated is then exactly the same as if SWIG had parsed the two
overloaded methods. The scripting languages count the arguments passed and call
the appropriate method, just like overloaded methods. C# and Java are now able
to properly wrap methods with default arguments by generating extra methods,
again as if the method was overloaded, so for:
void bar(string s="hello", double d=10.0, int i=0);
the following proxy methods are generated:
void bar(string s, double d, int i);
void bar(string s, double d);
void bar(string s);
void bar();
The new approach comes with a couple of minor knock on effects.
1) SWIG support for default arguments for C (not C++) code no longer works.
Previously you could have this interface:
%{
void foo(int val);
%}
void foo(int val=0);
and call the wrapped method from a scripting language and pass no arguments
whereupon the default of 0 was used. You can get the same behaviour for C
code by using the "default" typemap:
%typemap(default) int val "$1 = 0;"
%{
void foo(int val);
%}
void foo(int val);
or you could of course compile your code as C++ if you want C++ features :) :
%{
void foo(int val=0);
%}
void foo(int val=0);
A couple of SWIG's libraries used this C extension and these have been modified
to use the "default" typemap. The "default" typemap is thus unchanged (and still
is not and is not fully supported by C# and Java, and is likely to remain so).
2) All features (%feature, %rename, %ignore etc) no longer work as if the method
with default arguments is just one method. For example, previously
%ignore foo(int);
would have ignored the method completely. Now it will only ignore foo(int) but
not the extra foo() method. Instead use:
%ignore foo;
to ignore them all. or
%ignore foo(int);
%ignore foo();
This of course allows one to fine tune the wrapping, for example one could use:
%rename(fooint) foo(int);
%rename(foodefaults) foo();
void foo(int val=0);
and call them from any language like so:
fooint(200)
foodefaults()
or for example ignore the extra overloaded method, so the defaults cannot be used:
%ignore foo();
void foo(int val=0);

[Python]
- More cleaning up and uniformation on the Python Lib
- Added Robin's docstring patch, plus some fixes, plus
some extensions, see autodoc.i example in the test-suite,
and try using %feature("autodoc","extended").
This patch is not a complete solution for the
documentation problem, just enough to inform python about
the parameter list.
The expected swig documentation support is far far away yet.
10/1/2004: mmatus
- Fix the %callback feature (only used in ruby and python examples,
by now, but it should be generic), now member callbacks
are working again
- Fix wrapping of functions pointers like
std::ostream& std::endl(std::ostream&);
ie, the ones that return references or enums.
[Python] Add the %pythoncallback directive, which is
an improved version of %callback, ie,
%pythoncallback(1) foo;
%pythoncallback(1) A::bar;
%pythoncallback(1) A::barm;
int foo(int a) {
return a;
}
struct A
{
static int bar(int a);
int barm(int a);
};
int foobar(int a, int (*pf)(int a));
in python you can use
foo(2)
foobar(2,foo)
A.bar(2)
foobar(2,A.bar)
ie, no additional pointer elements are created, and
the original 'foo' and 'A.bar' can be used as parameters.
In the case of member function however, still you need
to use the special variable Class::<fnc_name>_cb_ptr, ie:
foobarm(3, a, A.barm_cb_ptr)
we will try to fix this situation also, but later.
[Python] Add more elements from the STL library, now
you can use
import std
std.cout << "hello " << 123 << std.endl
[Python] Fix in/out return mechanism, now swig will behave
as 1.3.21 but using a python list when needed. The problem
is that the types std::pair,std::vector,etc, use tuples,
and they interfer with the previous inout tuple type.
By using lists we solve the conflicts, swig acts as before,
but returns a list when more than one parameter are using
the OUT typemap. See the new inout.i example in the
test-suite.
*** POTENTIAL INCOMPATIBILITY FOR PYTHON MODULE ***
[Python] Much better error messages for bad arguments, now
you always get the argument number where the error occurred.
09/27/2004: wsfulton
Patch from Bill Clarke -
1) Warning emitted when -importall and -includeall is used together,
with -includeall taking precedence.
2) Ensure SWIGIMPORTED is always defined when a file is being
imported with %import. Note that this is not the same as SWIGIMPORT,
which gets defined in all generated wrapper files.
09/26/2004: mmatus
- add %feature("exceptionclass") to identify a class used
as exception. Before swig identified and marked a class
using the "cplus:exceptionclass" attribute. However, the
class needed to appear on an throw() statement. Now
swig keeps trying to identify the exception classes, as
before, but it also allows the user to mark a class by
using the %feature explicitly. (mostly relevant for
python and chicken)
[Python]
- fix -modern option + exceptions, which mix old class
style with the new one. So, we always need to emit
the "nonmodern" python code.
- add the "python:nondynamic" feature and its handler
now if you have
%pythonnondynamic A;
struct A {
int a;
int b;
};
then, in the python side
aa = A()
aa.a = 1 # ok
aa.b = 2 # ok
aa.c = 3 # error, the class can not be extended dynamically.
Since this is a feature, you can use
%pythonnondynamic;
or
%pythondynamic; [ Note: %pythondynamic since deprecated ]
to force all the wrapped classes to be "nondynamic" ones.
The default, as in regular python, is that all the wrapped
classes are dynamics. So, careful with your spelling.
09/14/2004: mmatus
- Support the -I- option.
- Differentiate between %include <file> and %include "file".
This fix several corner cases.
[Python] Several patches:
- Normalize the Lib file names:
*.swg internal files,
*.i user files.
- Fix Char[ANY] typemaps, so they also delete any extra '\0' chars,
now they behave as before (1.3.21). Still, you can use
the SWIG_PRESERVE_CARRAY_SIZE macro if you need to
preserve the original size (see pystrbase.swg).
- Add the Char FIXSIZE[ANY] typemaps, to preserve the
original C array sizes (see above). Though, you can't
use them yet since %apply and arrays are not working
together.
- Add pyfragments.swg, now the user can add fragments
to override the default ones.

[Perl] Applied patch #1019669 from Christoph Flamm. Adds support
for %feature("shadow") in the same way as it works in Python. This
enables one to override the generated shadow/proxy methods, including
constructors and destructors. For example:
/* Let's make the constructor of the class Square more verbose */
%feature("shadow") Square(double w)
%{
sub new {
my $pkg = shift;
my $self = examplec::new_Square(@_);
print STDERR "Constructed an @{[ref($self)]}\n";

[Python] Incompatibility reported by Bill Clarke (llib@computer.org):
If you are using Sun Studio 8 (and possibly earlier
versions) to compile the output produced by swig
1.3.22rc1, and you are using C++ and STL templates then
you need to use either "-runtime" or "-noruntime". If you
use neither of these options then you will probably get
compiler errors when trying to compile the wrapper file;
the error message will be like this: The name
SWIG_Python_ConvertPtr[...] is unusable in static
swigpy::traits_asptr[...] If you get this error message,
you need to regenerate your wrapper file using 'swig
-runtime' or 'swig -noruntime'.
You shouldn't get this problem with Sun Studio 9.

[Allegro CL] Use typemaps "ffitype" and "lisptype" to determine the FFI type
specifiers from the C type. This makes it possible, for instance, to control

The default (taking Lisp characters) is done by these built-in typemaps:
%typemap(ffitype) char ":char"
%typemap(lisptype) char "character"
If char means an integer instead, use these typemaps:
%typemap(ffitype) char ":char"
%typemap(lisptype) char "integer"

As discussed in bug #772453, the SWIG library directory is now installed
into a different default directory. The library used to be installed to
/usr/local/lib/swig1.3. It is now in the more usual architecture independent
directory and I have additionally used a version specific subdirectory as
the library will rarely work with older versions of SWIG. This release
will thus use /usr/local/share/swig/1.3.22 by default, which can be
tailored as before using './configure --swiglibdir'.

Patch #864689 from Robin Dunn:
This patch corrects two problems in the XML output of SWIG:
1. There were often extra '/>\n' in the output.
2. value attributes were output with '\n' in them but
since that is not technically legal most (all?) XML
parsers will strip them out. Replacing the '\n' with
the '&#10;' entity reference solves this as that is
legal and XML parsers will convert it to a '\n' when
reading the values back in.
This patch also adds a new global command line option
that will allow the parse tree to be written out in XML
*after* some other language module has been run, in
order to be able to get extra info that the language
module puts in the tree. In this way the XML is a
post-processed version of the tree rather than a
pre-processed version.
Command line option is -dump_xml or -xmlout <file>

patch #908951 from Robert de Vries.
07/08/2004: wsfulton
The deprecated runtime library build has been removed. This also removes
the dependency on Libtool. Libtool is no longer required to build SWIG.
The associated -ldflags SWIG commandline option has also been removed.
The examples and test-suite testcases that used the runtime library have
been updated to use the replacement approach to using SWIG across
multiple modules, that is they use the -noruntime and -runtime commandline
options, see Modules.html. Effectively they build their own runtime
libraries using -runtime. The examples are import and import_template.
The test cases are in the imports and template_typedef_import directories.
Anyone who wants the original runtime libraries can either run the test-suite
or build the examples and use the appropriate shared object/DLL that is
generated with the -runtime commandline option. For example libimports_runtime.so
(Python calls it lib_imports_runtime.so) is generated after running the
'make imports.multicpptest' testcase in the Examples/test-suite/<lang>
directory. Or use libruntime.so / runtime.dll after building the import
examples in Examples/<lang>/import.

06/27/2004: wsfulton
[Java] New feature for Java exceptions with format %javaexception(exceptionclasses).
This feature is a slight enhancement to %exception and the only difference is the
addition of the exception classes which are generated into a throws clause.
The 'exceptionclasses' is a comma separated list of classes which will be
added to the associated proxy method's throws clause. The 'exceptionclasses'
are specified like the exception classes in the 'throws' attribute in the
typemaps. This feature should be used for correctly handling checked exceptions
thrown from JNI code. For example:
%javaexception("java.lang.Exception") throwException %{
... convert a std::logic_error into a java.lang.Exception using JNI code ...
%}
#include <stdexcept>
void throwException() {
throw std::logic_error("Logic error!");
}
will generate a method with a throws clause in the module class:
public static void throwException() throws java.lang.Exception { ... }
06/27/2004: wsfulton
[C#] New %csconstvalue(value) feature directive for use with constants and
enums. This works the same way as %javaconstvalue. For C#, this directive
is the only way that one can fix wrapping of C/C++ enums with proper C#
enums if the enum item's initialiser cannot compile as C# code. This is
because Java enums can use a call into C code to initialise the enum item,
whereas in C#, the enum value must be a compile time constant. That is,
using %csconst(0) cannot be used in C# to initialise the C# enum item via
a PINVOKE call.
06/27/2004: wsfulton
[Java] New %javaconstvalue(value) feature directive for use with constants and
enums. Sometimes the use of %javaconst(1) will produce code that won't compile
under Java. If a compile time constant is required, %javaconst(0) is not an
option. The %javaconstvalue directive achieves this goal and the value specified
is generated as Java code to initialise the constant. For example:
%javaconst(1);
%javaconstvalue(1000) BIG;
%javaconstvalue("new java.math.BigInteger(\"2000\")") LARGE;
%javaconstvalue(10) bar;
%{
const int bar = 10;
%}
%inline %{
#define BIG 1000LL
#define LARGE 2000ULL
enum Foo { BAR = ::bar };
%}
Generates:
public interface exampleConstants {
public final static long BIG = 1000;
public final static java.math.BigInteger LARGE = new java.math.BigInteger("2000");
}
public final class Foo {
public final static Foo BAR = new Foo("BAR", 10);
...
}
Previously, none of BIG, LARGE or BAR would have produced compilable code
when using %javaconst(1).
06/27/2004: wsfulton
%feature enhancements. Features can now take an unlimited number of attributes
in addition to the feature name and feature value. The attributes are optional
and are much the same as the typemap attributes. For example, the following
specifies two optional attributes, attrib1 and attrib2:
%feature(featurename, attrib1="attribval1", attrib2="attribval2") name "val";
%feature(featurename, val, attrib1="attribval1", attrib2="attribval2") name;
06/27/2004: wsfulton
%feature improvements for the syntax that takes the feature value within the
%feature() brackets. The value specified is no longer restricted to being just
a string. It can be a string or a number. For example, this is now acceptable
syntax:
%feature("featurename",20.0);
whereas previously it would have to have been:
%feature("featurename","20.0");
Useful for features that are implemented as a macro, for example:
#define %somefeature(value) %feature("somefeature",value)
These will now work accepting either a string or a number:
%somefeature("Fred");
%somefeature(4);

[Java] Typemap changes for the Java proxy / typewrapper and enum classes. A new
typemap called javabody contains the essential support code for generation into the body
of these classes. There is also a new javabody_derived typemap which is used instead for
wrapped classes that have a wrapped base class. The code is basically, the getCPtr()
method and swigCPtr and swigCMemOwn member variables. These used to be hard coded
with no way to modify the code. The introduction of this typemap makes it possible for
the user to tailor nearly every aspect of the code generation.
The exception now is the code for director classes.
The javagetcptr and javaptrconstructormodifiers typemaps are deprecated and are
no longer used as the code that these generated can be put in the more flexible
javabody and javabody_derived typemaps.

[Java, C#] The contents of the class modifier typemaps and pragmas have changed.
They must now include the class type. Previously 'class' was hard coded.
This change enables flexibility into what type of class is generated,
for example the proxy class could be an interface instead of a class.
For Java this affects the javaclassmodifiers typemap and the jniclassclassmodifiers
and moduleclassmodifiers pragmas.
For C# this affects the csclassmodifiers typemap and the imclassclassmodifiers
and moduleclassmodifiers pragmas.
Unless you have overridden the default versions of these typemaps or pragmas, you
shouldn't be affected. However, if you have, upgrading is easy, for example
class Foo {};
%typemap(javaclassmodifiers) Foo "public final"
must now be:
class Foo {};
%typemap(javaclassmodifiers) Foo "public final class"

Unnamed enum global variables are now supported in addition
to the recently added support for unnamed enum member variables.
For example:
struct Foo {
enum { enum1, enum2 } MemberInstance;
};
enum { enum3, enum4 } GlobalInstance;
The int typemaps are used for wrapping the get/set accessor methods.
If the sizeof an enum is not the same size as an int then setting the
variable will silently do nothing as the casts cannot be easily and portably
generated. If you need to solve this highly obscure situation, write
the assignment using the %exception feature.

[C#] C# enum wrapping mods. Similar to the Java module, enums can be wrapped using
one of 3 approaches:
1) Proper C# enums - use %include "enums.swg"
2) Typesafe enums - use %include "enumtypesafe.swg"
3) Simple constant integers (original approach) - use %include "enumsimple.swg"
See each of these files for further details. Each of these files use typemaps
and a new feature to control the generated code. The feature is:
%csenum(wrapapproach);
where wrapapproach should be one of: "proper", "typesafe", "typeunsafe" or "simple".
[No implementation deemed necessary for type unsafe enums].
The default approach is proper C# enums. Anonymous enums are always wrapped by
constant integers.
*** POTENTIAL INCOMPATIBILITY FOR C# MODULE ***
05/20/2004: wsfulton
[Java] Java enum support added. There are now 4 ways in which enums can be wrapped:
1) Proper Java enums - use %include "enums.swg"
2) Typesafe enums - use %include "enumtypesafe.swg"
3) Type unsafe enums (constant integers) - use %include "enumtypeunsafe.swg"
4) Simple constant integers (original approach) - use %include "enumsimple.swg"
See each of these files for further details. Each of these files use typemaps
and a new feature to control the generated code. The feature is:
%javaenum(wrapapproach);
where wrapapproach should be one of: "proper", "typesafe", "typeunsafe" or "simple".
The default typemaps will handle enums that may or may not have specified initial
values, for example ten is specified:
enum Numbers { zero, ten(10) };
However, the amount of generated Java code can be cut down, by modifying these typemaps
if none of the enums have initial values (proper Java enums and typesafe enums approach).
The default approach is typesafe enums. Anonymous enums are always wrapped by
constant integers.

enum Grammar { Subject, Object };

[Guile] New runtime functions SWIG_PointerAddress,
SWIG_PointerType, SWIG_IsPointerOfType, SWIG_IsPointer.
[Guile] In -scm mode, wrap several SWIG runtime functions

[Guile] GOOPS proxy objects now also print the pointer
address of the C object.

Added Kou's patch for the Ruby %import directive so that modules
with "nested" names are handled properly. Consider an interface
file foo.i that has this %module declaration at its top:
%module "misc::text::foo"
Now consider another interface file spam.i that imports foo.i:
%import foo.i
Before this patch, this would result in the following code being
generated for spam_wrap.c:
rb_require("misc::text::foo");
With this patch, however, you'll get the correct path name
for the call to rb_require(), e.g.
rb_require("misc/text/foo");

[Chicken] Fix bug 782468.
To fix this bug, the runtime code has been rewritten, and
pointers are now represented as a C_SWIG_POINTER_TYPE.
Chicken version > 1.40 is now required!
* Typemap incompatibility: typemaps no longer use chicken_words.
If a typemap needs some space, it should just call C_alloc
* argout typemaps no longer use the /* if ONE */ construct to
build an output list. A SWIG_APPEND_VALUE macro, exactly like
guile and mzscheme is now used.
04/25/2004: mkoeppe (Matthias Koeppe)
[Guile] In the generated GOOPS code, don't create methods
that would not specialize any arguments; simply re-export
the primitive functions. (This is a performance
optimization which reduces load time and execution time.)
[Guile] In -gh mode, fix the "too many initializers" error
which was caused by an incompatible swig_type_info layout.
[Guile] The typemap for FILE * in ports.i now also accepts
a regular FILE * pointer object. Also a bug with Scheme
file ports that are open for input and output has been
fixed.

Change entry 03/21/2004 revoked. The change introduced another
inconsistency (reference typemaps beings used instead of
pointer typemaps for member variables as well as static
member variables and global variables for some languages,
but only for C++ and not C). This would break user's current
typemaps and introduce further inconsistencies. Alternative
solution required and being discussed.
04/10/2004: mmatus (Marcelo Matus)
Added the -directors flag. This enables the director
mode for the interface and all the classes that
don't set the "feature:nodirector" explicitly.
You can use this in your module if you want to use the
director feature in all your classes, but it is most
intended for testing purposes, like:
make check-python-test-suite SWIG="../../../swig -directors"
make check-ruby-test-suite SWIG="../../../swig -directors"
make check-java-test-suite SWIG="../../../../swig -directors"
These commands will run the entire test-suite using
directors, and not only the specific 'directors_*'
cases. This should be done from time to time.

[python] Added support for std::wstring and wchar_t,

04/10/2004: mmatus (Marcelo Matus)
[python] Fix the default behaviour (seg. fault) when an
inplace operator (+=,-=,...) was wrapped, as reported by
Lucriz (lucriz@sitilandia.it), when the most common
form was used:
A& A::operator+=(int i) { ...; return *this; }
^^^^ ^^^^^^
ie, an object is returned and its contains the same 'this'
value than the input object, which is deleted after the
operation "a += b", leaving the result with no real
object, but a seg. fault.
To fix it, we needed to introduce a new feature and use an
old one:
%feature("self:disown") A::operator+=;
%feature("new") A::operator+=;
here, "self:disown" disable the ownership of the 'self'
or input object, and the "new" feature transfers the
ownership to the result object.
The feature/solution could also be used in other languages
that use gc and implement the inplace operators, or other
operators, in a similar way.
*** POTENTIAL INCOMPATIBILITY FOR Python MODULE ***
If you already are using the inplace operators in python,
and you implemented some kind of workaround to the problem
fixed here, it is possible you could end with 'free'
objects that never get deleted. If that is the case, and
you want to disable the current fix, use:
%feature("self:disown","") A::operator+=;
%feature("new","") A::operator+=;
04/07/2004: cheetah (William Fulton)
[C#] C++ enums are no longer wrapped by integers, they are now wrapped by
C# enums. For Example, given C++:
enum AnEnum { foo, bar };
typedef AnEnum AnEnumeration;
void something(AnEnum e, AnEnumeration f);
The following is generated:
public enum AnEnum {
foo,
bar
}
public static void something(AnEnum e, AnEnum f) {...}
Note that a global enum like AnEnum above is generated into its own
file called AnEnum.cs. Enums defined within a C++ class are defined
within the C# proxy class. Some of the typemaps for modifying C# proxy
classes also work for enums. For example global enums can use
%typemap(csimports) to add in extra using statements.
Global enums and class enums can use
%typemap(csclassmodifiers) to make the enum private, public etc.
%typemap(csbase) to change the underlying enum type (enum base)
If we add this for the above example:
%typemap(csclassmodifiers) AnEnum "protected"
%typemap(csbase) AnEnum "long"
the following is generated:
protected enum AnEnum : long {
foo,
bar
}
*** POTENTIAL INCOMPATIBILITY FOR C# MODULE ***

Seg fault fix for empty enums, like
enum Foo {};
03/21/2004: mmatus
[Note: this change revoked on 04/25/2004]
[Python] Makes the following 'var' cases more uniform:
std::string ga;
struct A {
static std::string sa;
std::string ma;
};
now the three variables (ga, sa, ma) can be assigned as:
cvar.ga = "hello";
A.sa = "hello";
a.ma = "hello";
ie, now 'ma' will also use a std::string typemap 'in' if
defined, before it was only accepting a 'p_std_string'
pointer. Note, however, that 'ma' will not use the
'varin/varout' typemaps (that probably could be more
natural), but it will pick up the 'in' typemap for const
std::string& (which is easier).
The changes in cwrap.c and lang.cxx will probably fix the
behaviour in other languages that do not overload the
membervarHandler method "too much".
03/21/2004: mmatus
[Python] Disabling the default instantiations like:
%template() std::pair<int,int>;
for all the primitive types and STL containers/classes.
They are expensive, specially for pair and map, and the
previous behaviour also requires the user to perform
manual instantiations. Still, if the speed difference is
not important, it can be re-enabled by defining the macro
SWIG_STD_DEFAULT_INSTANTIATION (see std_common.i).
Also, normalizing the INPUT/OUTPUT/INOUT typemaps. Now
they use the same conversors than the rest of the
typemaps, and you can use them for std::pair, std::string
and all the other STL types, like in:
void p_inoutd(std::pair<double, double> *INOUT);
Added the attribute.i and implicit.i files with macros to
transform functions pairs like 'set_x'/'get_x'
(or 'T& x()'/'const T& x() const') into an attribute,
and allowing the use of implicit constructors in typemaps
(see the files for more details).
03/21/2004: mkoeppe
[Guile] Fix the documentation strings of functions with
anonymous arguments.
03/18/2004: mmatus
[Python] More general std_string.i interface.
Now you can wrap it using
%template(string) std::basic_string<char>;
and use the std::string as a base class:
struct A : std::string {
};
But more important, swig will recognize
both std::basic_string<char> and std::string as
the same type.
03/16/2004: mmatus
Previously added, but not mentioned before:
- friend declaration support, swig now emits a global
function in the same class scope.
- ref/unref features: to mix ref counting C++ classes
and native script ref counting mechanisms (like in python).
Use it like:
%feature("ref") RCObj "$this->ref();"
%feature("unref") RCObj "$this->unref();"
And the class RCObj, and all the derived ones, will
perform the right ref/unref calls when a new pointer
is returned to the target language, or when the target
language attempts to delete the object.
See the refcount.i file in the test-suite for more
details.
03/16/2004: mmatus
[Python] Using the new %fragment support, major rewrote
of the python swig library, including:
- Almost automatic template/typemap instantiation for
the STL components. For example, now you can write:
%template(vector_i) std::vector<int>;
and a specialized vector_i class is emitted with all
the needed typemaps. No need to use the old
'specialize_vector' macros.
Note you can also define
%template(matrix_i) std::vector<std::vector<int> >;
%template(vector_pii) std::vector<std::pair<int,int> >;
- The empty template instantiation
%template() std::vector<int>;
defines the vector typemaps, but no proxy class. For all the
fundamental types, the empty template instantiation are
defined, so, you can say
%include std_vector
int func(const std::vector<int>& a);
where the proper typemap is applied to 'a', but no
std::vector<int> proxy is generated.
- All the STL containers present a more uniform behavior and
more complete interface declaration. The following are
now supported:
std::vector<T>
std::list<T>
std::deque<T>
std::set<T>
std::multiset<T>
std::map<T>
std::multimap<T>
not a container, but also supported:
std::pair<T,U>
also, more typemaps are defined for all of them,
including varin, varout, typecheck, etc.
- Initial attempt to implement the STL containers
considering allocators, ie:
std::vector<T,A>
it is partially working, but it is just a workaround
while swig improves its template type support.
Please test with your particular setup. It seems to be
working with g++ 3.2.2, g++ 2.96, Intel icc and SGI CC
compilers, plus python 1.5.2, 2.0 and 2.3, but since
we are using templates, there is a chance you can find
some problems when using with an old C++ compiler.
03/16/2004: mmatus
- Allowing the empty %template directive, such as
%template() std::vector<int>;
to process the class "typedef"s and "typemap"s. Before
only the internal "typedef"s were processed.
This makes possible to emit the default in/out
typemaps without the need of wrapping an specialized
vector instance.
- Adding the preprocessor extension #@ which mangles the
following macro argument, like in:
#define macro(X) #@X
macro(int) -> int
macro(std::string) -> std_s_s_string
- Fragments can now be "type specialized", as the typemaps. The
syntax is as follows
%fragment("name","header")
{ /* a type independent fragment (old syntax) */ }
%fragment("name" {Type}, "header")
{ /* the fragment is type dependent */}
Now fragments can also be used inside templates:
template <class T>
struct A {
%fragment("incode"{A<T>},"header") {
/* 'incode' specialized fragment */
}
%typemap(in,fragment="incode"{A<T>}) {
/*
here we use the 'type specialized'
fragment "incode"{A<T>}
*/
}
};

[Java, C#] Overloading changes:
- Methods which are overloaded in const only no longer generate Java
code that won't compile - the first method parsed is used and a
warning is displayed. Note that this behaviour is slightly different
to the scripting languages which always uses the non-const method.
- Warning messages 509 and 512 replaced by new warning number 516, which
is more relevant to these statically typed languages as the overloaded
methods aren't 'shadowed', they are ignored.

Revived the NextStep port of SWIG.
Fixed fatal problem in DohStrstr() caused by difference in strstr()
implementation which made %apply become entirely dysfunctional. On
NextStep, strstr("foo","") evaluates to NULL; whereas, on modern
platforms, it evaluates to "foo". %apply relies extensively upon
strstr("foo","") evaluating to non-NULL, therefore it failed
catastrophically when faced with NextStep's strstr().
Added `bool' check to configure.in since NextStep's C++ compiler
does not supply this type. swig.h now fakes up `bool' if needed.
Worked around NextStep C++ compiler bug in which C++ code is
disallowed inside extern "C" functions. This problem affected all
language modules, since they publish hook functions of the form:
extern "C" Language *swig_foo(void) { return new FOO(); }
Fixed by creating a C++ wrapper:
static Language *new_swig_foo() { return new FOO(); }
extern "C" Language *swig_foo(void) { return new_swig_foo(); }
Ensured that Swig_copy_string() is used in place of strdup() since
NextStep does not supply strdup().
Fixed detection of Ruby library name and location in configure.in.
Problem 1: Assumed that library always resided in Ruby's "archdir",
which was correct for Ruby 1.6.x, but which is incorrect for Ruby
1.8.x, in which case the library normally resides in Ruby's
"libdir". Problem 2: Assumed that the library could always be
linked via "-l"+RUBY_INSTALL_NAME (where RUBY_INSTALL_NAME
typically is "ruby"), however this failed for platforms, such as
NextStep, which do not support shared libraries. In this case, the
static library name in 1.8.x is libruby-static.a, thus
-lruby-static is required. The new logic works correctly for
static and shared libraries for 1.6.x and 1.8.x.
Fixed detection of Perl CFLAGS in configure.in for NextStep.
Detection code extracted CFLAGS from Perl's %Config hash but
neglected to add a newline to the value before passing it through
`sed'. NextStep's ancient `sed' discards input which is not
terminated with a newline, thus Perl CFLAGS always evaluated to the
empty string.

Tidy up in the exception handling code that is generated when
C++ exception specifications are wrapped with the throws typemap.
This redundant code is no longer generated:
catch(...) {
throw;
}
01/12/2004: wsfulton on behalf of mmatus (marcelo matus)
if a method uses %exception and the method requires the use
of the throws typemap, the code in a throws typemap will be
generated inside the try body. For example:
%exception method {
try {
// method action
$action
} catch (int i) {
// method int catch handler
} catch (...) {
// method generic catch handler
}
}
%typemap(throws) Except %{
// throws typemap Except catch handler
%}
%inline %{
class Except {};
void method(int i) throw (Except);
Will generate:
{
try {
// method action
try {
method(arg1);
}
catch(Except &_e) {
// throws typemap Except catch handler
}
} catch (int i) {
// method int catch handler
} catch (...) {
// method generic catch handler
}
}
As can be seen, the inner try catch block is for the throws typemaps.
Previously, this was reversed so that the inner try catch block
was the %exception code. In the example above, it would have been
impossible to catch Except as the catch all (...) would catch the
exception instead.

The output format for both warnings and errors can be selected for
integration with your favourite IDE/editor. Editors and IDEs can usually
parse error messages and if in the appropriate format will easily take you
directly to the source of the error. The standard format is used by
default except on Windows where the Microsoft format is used by default.
These can be overridden using command line options, for example:
$ swig -python -Fstandard example.i
example.i:4: Syntax error in input.
$ swig -python -Fmicrosoft example.i
example.i(4): Syntax error in input.

Weakened warning message related to constructor names so that an
unusual nested-class wrapping technique would work again (apparently
it worked in some older SWIG releases). For example:

class ClassA;
class ClassB;
};
class Scope::ClassA {
...
};
class Scope::ClassB {
...
}
Note: There is still some odd interaction with the SWIG symbol

[Java] Protected class methods are wrapped as protected Java methods
when using the dirprot director feature. This can be changed using
%javamethodmodifiers to something else should the need arise, for
example, private or package access.
12/11/2003: cheetah (William Fulton)
[Java, C#]
%javamethodmodifiers (Java) and %csmethodmodifiers (C#) operate slightly
differently. Previously this feature had to be present to set the method
modifiers. Now it is only used if it exists for the method being wrapped.
The default is "public" as previous however, when wrapping protected
director methods it is "protected". This change will not affect existing
use of the %javamethodmodifiers or %csmethodmodifiers.
12/11/2003: mmatus (Marcelo Matus)
This fix some recurring reports about keywords not been
properly identified and warned, and it solves the problem
of how to add a test file to the test-suite such that it
doesn't use any keyword of all the supported languages
(and doing it without compiling the test for all the
supported languages, thing that is not always possible,
and without requiring you to know all the supported
language keywords, thing that is always impossible).
So these are the changes globally speaking:
- Uniform the definition of the keyword warnings through
the supported languages: all the languages has now a
separate file that defines the keywords or bad names:
python/pythonkw.swg
chicken/chickenkw.swg
....
- Added keyword list for most of the languages that didn't
have one (using the new separated file).
- Added the "All keywords" warning support: -Wallkw option.
This option allows you to include all the known keywords
for all the supported languages, and can be used as:
swig -Wallkw ....
This will help to the process of adding a test-suite
file that can be compiled in all the swig supported
languages, and it will be also helpful for users who
want to create multi-language libraries.
And these are the detailed changes (mostly file addition):
- For the languages that already have some sort of keyword
warning list, move it to an external languagekw.swg
file, ie:
move keywords from python.swg -> pythonkw.swg
move keywords from chicken.swg -> chickenkw.swg
move keywords from tcl8.swg -> tclkw.swg
and re-include languagekw.swg from language.swg.
- For the language that didn't have a keyword list, and
for the ones that I could find a list, add the
languagekw.swg file, ie:
csharp/csharpkw.swg
java/javakw.swg
php4/phpkw.swg
pike/pikekw.swg
ruby/rubykw.swg
also add a line in language.swg to include
languagekw.swg, but now it is commented!!!, like in
java.swg:
/* java keywords */
/* please test and activate */
//%include "javakw.swg"
ie, there will be no change in how swig runs normally
until the language maintainer test and uncomment that
line.
So, please check each languagekw.swg file (I left the
link to the keyword list source for checking), and after
testing, uncomment the %include line.
- Added the file allkw.swg, which includes all the
languagekw.swg files.
For the languages that has no languagekw.swg file right
now, and if they need one, add the file into the
language directory, and add the corresponding include
line into the allkw.swg file.
- Added the -Wallkw that includes the allkw.swg file.
Note that the old -lallkw.swg option couldn't be used
since it include the file after it would be needed.
Hopefully, the -Wallkw option will be added to the default
rules in the related test-suite Makefiles, so, when
creating a new test, or adding a new swig library file
(like _std_deque.i), swig will warn you if you are using a
bad name, considering all the language where it needs to
run.
Right now you can test it by using:
make check-python-test-suite SWIG="swig -Wallkw"
or using your favorite target language, it doesn't matter.
And yes, there are several examples that are using
reserved keywords, specially from csharp.
*** Remember ****: the new keyword warning lists are not
included by default in any of language that before didn't
have one. To enable the keyword warnings as the default
behavior, the inclusion of the languagekw.swg file has to
be uncommented at each language.swg file.
So, all the language maintainers, please check the
keywords list.
Also, you can add buit-in names, and not only keywords, like
'True/False' in python. Remember that you can be more
specific and refer only to member names, like *::configure
or *::cget (see an example in the tcl8/tcl8kw.swg file),
or only global names, like ::range (see an example in the
python/pythonkw.swg file.
Just to be consistent, use the following codes:
- Use code 314 for keyword and/or fatal bad names.
- Use code 321 for buit-in and/or not fatal bad names.
so, they can't be disabled/enabled independently (see
python/pyhtonkw.swg for examples).
**** And don't add any new test file without checking it
with the -Wallkw option!! (that includes me) *****.

b.do_hi() # RuntimeError, do_hi() is protected!!
f.do_hi() # RuntimeError, do_hi() is protected!!
b.do_hello() # RuntimeError, do_hello() is protected!!
f.do_hello() # Ok, since it its redefined in python.
Here Bar.do_hello is always protected, but Foo.do_hello
is "public", because it is redefined in python. Before,
all the 'do_hello' methods were public.
This seems to be a good compromise between C++ and python
philosophies, ie, all the director protected methods keep
protected at the user side (C++ way) until they are
redefined (python way, were all defined methods are always
public). And this is not only a good compromise, it also
seems to be the only way to do it :).
Now ruby has native director protected members, and python
pure runtime support. I guess these are the two possible
extreme cases. And hopefully, they could be used as
templates to modify the other languages that support
directors, so they can "reprotect" the protected director
members at the target language side.
This finished the director protected support for the
python language. Ocalm will need to add the
"reprotection" later.

The following case (reported by Lyle Johnson) was fixed:
%rename(x) Foo::y();
class Foo {
public:
void y();
protected:
int x;
};
swig warned that the symbol 'x' was already defined, and
the renaming fails. 'x' was not emitted, since it is
protected, but it was kept in the symbol table with too
much information.
Now swig works for all the cases (plain, director and
dirprot) again. This was fixed by allowing the parser.y to
decide much closer what to do with 'x'. Before all the
discarding or generation was resolved at the lang.cxx
stage. Also the changes in parser.y to implement the
director protected mode are now much more encapsulated, and
they get disabled if the mode is not enabled. Before the
deactivation was done at the generation stage (lang.cxx).
By the other hand, if the director mode is enabled, and
%rename is done, reusing a protected member name, there is
a pathological case:
%rename(x) Foo::y();
class Foo : public A {
public:
void y();
protected:
int x; /* works */
static int x; /* works */
static void x(); /* works */
typedef void x(); /* works */
virtual void x(); /* always fails, as it should, since
Foo::x() will be emitted in the
director */
void x(); /* always fails, but sometimes it shouldn't,
since the Foo::x() will not be emitted if
it is not virtual */
};
The last case is not always right because at the parser.py
stage it is not possible to decide if the protected member
Foo::x() could or not conflict with the renamed Foo::y(),
since Foo::x() could be virtual by inheritance.
I guess this just an intrinsic limitation, and no much can
be done about it without resorting into larger changes to
postpone, under certain conditions, the multiply symbol
detection (lang.cxx stage).
So, by now, it is just considered a well known "feature" in
the director protected mode. The good news is that it seems
to be a rare case, and it can be avoided by the user by
hiding 'x' before renaming 'y':
%rename(_x) Foo::x();
%rename(x) Foo::y();
12/08/2003: mmatus (Marcelo Matus)
The virtual method detections now properly
treats the following cases:
namespace foo { typedef int Int; }
struct A {};
typedef A B;
struct Foo {
virtual ~Foo() {}
virtual Foo* cloner() = 0;
virtual int get_value() = 0;
virtual A* get_class() = 0;
virtual void just_do_it() = 0;
};
struct Bar : Foo
{
Bar* cloner();
foo::Int get_value();
B* get_class();
void just_do_it();
};
All the Foo and Bar methods are virtual. A new attribute
"virtual:type" record the base polymorphic type. In the
previous cases we have:
type : Bar virtual:type : Foo
type : foo::Int virtual:type : int
type : B virtual:type : A
type : void virtual:type : void
This attribute is useful in languages (java+directors)
that could have problems redefining Bar* Bar::cloner().
If you never had code like the above, you will see no
effects. But if you have some code like that, you
will see some effects since some methods that
before were not properly treated as virtual,
will start to act like that. This could enlarge
your director classes.
12/08/2003: mmatus (Marcelo Matus)
The director protected member support (dirprot)
is disabled by default.
It can be enable by using '-dirprot' or by adding
the option to the module declaration, like:
%module(directors="1",dirprot="1") my_module
This module option was added to properly compile the
director_protected.i and director_nested.i examples.
The feature has been tested with python[2.2,2.3]
and ruby[1.6.7], both at compilation and runtime, and
java[j2sdk1.4.1_01], but only at compilation (my java
installation doesn't run any of the director examples,
olds nor news).
Please test for ocaml and java.
The errors reported by William and Scott were fixed,
except for a warning about SWIG_JavaThrowExecption()
multiply defined. I can't reproduce this error with my
examples. We will wait for Scott to send us a minimal
case.
12/07/2003: mmatus (Marcelo Matus)
The director protected member support has been
completly moved out from python.cxx, and now
resides in the common lang.cxx, emit.cxx and
allocate.cxx files.
This means it should work for all the other languages
that currently support directors, ie, python, java, ocalm
and ruby.
The change has been tested with python (compilation+runtime)
and java (just compilation).
Please add runtime tests for the missing languages
and test it.
The '-nodirprot' option was moved to the principal main,
and can be used from all the languages.

[Java] Fixed and improved error checking of STRING_OUT typemaps in
various.i.
12/04/2003: mmatus (Marcelo Matus)
- Now the virtual members with no explicit declarator
are properly identified:
struct A {
virtual int f() = 0;
};
struct B : A {
int f();
};
Here, B::f() is virtual, and the director and the
virtual elimination mechanism now recognize that.
- [C#] This fix also fixes the problem where 'override' was not being
used on any overridden virtual method, so for struct B above,
this C# code is generated:
public class B : A {
...
public override int f() {
...
}
...
}
- Initial support for protected virtual methods. They are now
properly emitted when using with director (python only by
now).
%feature("director") A;
struct A {
protected:
virtual int f1() = 0;
};
%feature("director") B;
struct B : A{
protected:
int f1();
virtual f2();
};
This can be dissabled by using the '-nodirprot' option.
- The feature 'nodirector' is working now at the top level,
so, it must work for all the languages:
%feature("director") A;
%feature("nodirector") A::f2;
struct A {
virtual int f1();
virtual int f2();
};
in this case, only 'f1' is exported to the director class.
- Added director support for const TYPE& arguments (python).

For instance:
class A {
public:
virtual void f(void) = 0;
};
class B {
public:
virtual void f(); // Not matched to f(void) correctly
};
The parser now normalizes all declarations of the form f(void)
in C++ classes to f(). This should fix a variety of subtle
problems with inheritance, optimizations, overloading, etc.

11/17/2003: mkoeppe (Matthias Koeppe)
[Guile] Improvements to object-ownership management in
"-scm" mode. (They do not apply to the default "-gh" mode.)
* Renamed the smob type that indicates that the object can
be garbage collected from "collected swig" to "collectable
swig", which is more precise.
* Export the destructor functions again. It is now
allowed to explicitly call destructors, even for
garbage-collected pointer objects. A pointer object
that has been passed to a destructor is marked in a
special way using a new smob type, "destroyed swig".
(This helps avoid nasty memory bugs, where references to
dead C objects are still held in Scheme. Moreover, the
garbage collector will not try to free a destroyed
object once more.)
* Destructor-like functions can also mark their arguments
as destroyed by applying the typemap SWIGTYPE *DESTROYED.
(It calls the function SWIG_Guile_MarkPointerDestroyed.)
* Functions that "consume" their objects (or that "own"
them after the call) can mark their arguments as
not garbage collectable. This can be done by applying
the typemap SWIGTYPE *CONSUMED. (It calls the function
SWIG_Guile_MarkPointerNoncollectable.)
* The macro TYPEMAP_POINTER_INPUT_OUTPUT from library
pointer-in-out.i creates additional typemaps
PTRTYPE *INPUT_CONSUMED, PTRTYPE *INPUT_DESTROYED.
They mark the passed pointer object likewise.
The typemap PTRTYPE *OUTPUT creates a garbage-collectable
pointer object, like %newobject does for a returned
pointer. Use the new typemap PTRTYPE *OUTPUT_NONCOLLECTABLE
to create a pointer object that will not be garbage collected.

[Python] When generating proxy class code, SWIG emits a few
default methods for __repr__() and other Python special
methods. Some of these methods are emitted after all of the
contents of a class. However, this makes it hard to override
the methods using %pythoncode and some other directives that
allow code to be inserted into a class. These special methods
are now emitted into the code *before* all of the other methods.
Suggested by Eric Jones.

Preprocessor enhancement. For include statements like this:
%include "foo/bar.i"
the directory "foo" is now added to the search path while
processing the contents of bar.i. Thus, if bar.i includes other

you would have to add additional directories using -I to make this
work correctly. Note: the C preprocessor seems to behave in
an identical manner on many (most? all?) systems.

*** INCOMPATIBILITY [Guile] ***
11/02/2003: mkoeppe (Matthias Koeppe)
Unify the pointer-conversion runtime API. The standard
functions are:
* SWIG_NewPointerObj (POINTER, TYPE, FLAGS)
-- Create an scripting object that represents a typed
pointer. FLAGS are language specific.
* SWIG_ConvertPtr (INPUT, RESULT, TYPE, FLAGS)
-- Get a pointer from the scripting object INPUT and
store it in the place RESULT. When a type mismatch
occurs, return nonzero.
* SWIG_MustGetPtr (INPUT, TYPE, ARGNUM, FLAGS)
-- Get a pointer from the scripting object INPUT and
return it. When a type mismatch occurs, throw an
exception. If ARGNUM > 0, report it as the
argument number that has the type mismatch.
[Guile]: No changes.
[MzScheme]: No changes.
[Perl]: Add the function SWIG_NewPointerObj.
The function SWIG_MakePtr is kept.
The function SWIG_MustGetPtr is currently not

Incorporated patch: [ 829325 ] new Python Module options and features.
Robin Dunn writes:
This patch makes a number of changes to the SWIG python module.
1. Add -apply option, and change the default code
output to use the foo(*args, **kw) calling syntax
instead of using apply(). If the -apply option is
given then code is generated as before. This is very
similar to Patch #737281 but the new -modern option
makes the second half of that patch unnecessary so it
is not included here.
2. Add -new_repr option. This is the same as my Patch
#797002 which I will mark as closed since it is no
longer needed. When this new option is used then the
__repr__ methods that are generated for proxy classes
will be more informative and give details about the
python class and the C++ class.
3. Add %feature("addtofunc"). It allows you to insert
one or more lines of code inside the shadow method or
function that is already generated, instead of
replacing the whole thing like %feature("shadow") does.
For __init__ it goes at the end, for __del__ it goes
at the begining and for all others the code generated
is expanded out to be like
def Bar(*args, **kwargs):
val = _module.Foo_Bar(*args, **kwargs)
return val
and the "addtofunc" code is inserted just before the
return statement. If the feature is not used for a
particular method or function then the shorter code is
generated just like before.
4. A little bit of refactoring to make implementing
addtofunc a little easier.
5. Added a -modern command-line flag that will cause
SWIG to omit the cruft in the proxy modules that allows
it to work with versions of Python prior to 2.2. The
result is a simpler, cleaner and faster python proxy
module, but one that requires Python 2.2 or greater.

Fixed a subtle problem with overloaded methods and smart pointers.
If a class has overloaded methods like this:
class Foo {
public:
int bar(int x);
static int bar(int x, int y);
};
and the class is used as a smart pointer:
class FooPtr {
public:
Foo *operator->();
};
The SWIG would try to expose the static member Foo::bar
through FooPtr---resulting bogus wrapper code and a compiler
error.
Due to the way in which overloading is handled, it is
extremely difficult to eliminate the static method in
this case. Therefore, it is still exposed. However,
the generated code now compiles and works.

[Python] Director constructors now default to __disown = 0,
which is the intended behavior and fixes the director_finalizer
test case under python.
09/12/2003: cheetah (William Fulton)
[C#] - Typemaps added for std::string and const std::string &.
- New delegate for creating a C# string given a char *. It
can be used by calling SWIG_csharp_string_callback as shown
in the std::string 'out' typemap. Useful if the return type is
mapped to a C# string and the calling function is responsible
for cleaning up memory as the C# garbage collector doesn't
free the memory created in C/C++ and then returned as a C# string.
- The exception delegates have moved into an inner class in the
intermediate class, thereby freeing up the static constructor.

(Internals)
Major refactoring of iteration over lists and hashes. The
DOH library now uses iterators. They work like this:
List *l = (some list);
Iterator i;
for (i = First(l); i.item; i = Next(i)) {
// i.item contains the actual list item.
// i.item is NULL at end of list
...
}
Hash *h = (some hash);
Iterator j;
for (j = First(h); j.item; j = Next(j)) {
// j.item contains hash table item
// j.key contains hash table key
// Both j.item and j.key are NULL at end
...
}
The old iteration functions Firstitem(), Nextitem(), Firstkey(),
and Nextkey() are gone.
The new iterators are simpler, result in better memory use,
and may be faster. Also, there are no longer any problems
iterating over the same list/hash in multiple places at
the same time. For example, this is fine:
Iterator i,j;
for (i = First(l); i.item; i = Next(i)) {
for (j = First(l); j.item; j = Next(j)) {
...
}
}
(This never worked in previous versions).
*** POTENTIAL INCOMPATIBILITY ***. This will probably break
third party extensions to SWIG (or give them further encouragement
to join the SWIG CVS-tree :-).

[Java] Directors implemented for Java. In summary this is a big new feature
which supports upcalls from C++ to Java. Code is generated to support C++
callbacks to call into Java and true polymorphic behaviour for Java classes
derived from C++ classes. See java.html for details. Contributed by

Created contract example directory at /SWIG/Examples/contract
Added simple contract examples (simple_c & simple_cxx)
Modified contract module's output format
*** NEW FEATURE ***
09/01/2003: cheetah (William Fulton)
Test-suite build improvements:
- Multiple build directories working for the test suite, so it is now
possible to run configure in multiple subdirectories and run the test
suite in each of these sub directories.
- 'make distclean' fixed so it doesn't bomb out on the Examples directory
when using multiple subdiretory builds. Required the following directories
to be moved:
Examples/GIFPlot/Perl -> Examples/GIFPlot/Perl5
Examples/GIFPlot/Php -> Examples/GIFPlot/Php4
These new directories used to be symbolic links to the old directory.
Also the Examples/test-suite/Perl symbolic link has been removed.
- Running the test-suite, other than from the root directory, say
in Examples/test-suite/python will now display all the code being
executed.
- The following 3 C# compilers are detected during configure and work with
the test-suite: Mono, Portable.NET and Microsoft.
09/01/2003: Tiger
Added inheritance support for design by contract feature.
09/01/2003: beazley
Fixed [ 794914 ] Wrong types in template specialization.
SWIG was not handling arguments correctly in template
partial specialization. For example,
template<class T> class Foo<T *> {
public:
T *blah();
};
%template(FooInt) Foo<int *>;
in this class, the return type of blah was set to
'int **', but it should really be 'int *'. This has been
fixed, but it will affect all prior uses of partial
specialization.

08/30/2003: mrose (Mark Rose)
Modified the director typemaps in python/std_complex.i to use the
new-style macro and conversion functions, which eliminated some
redundant code. Fixed a few bugs in these typemaps as well, although
more testing is needed.
08/29/2003: mrose (Mark Rose)
Completed initial support for wrapping abstract classes with directors.
Constructor wrappers will be generated for abstract classes that have
directors, and instances of the director classes will be created regardless
of whether the proxy class has been subclassed in the target language.
No checks are made during construction to ensure that all pure virtual
methods are implemented in the target language. Instead, calls to
unimplemented methods will throw SWIG_DIRECTOR_PURE_VIRTUAL_EXCEPTION
exceptions in C++.
Integrated Prabhu Ramachandran's typemap patches, which provide director
typemap support for enums and std::size_t, and fix a couple bugs in the
director std::vector<> typemaps.
08/29/2003: cheetah (William Fulton)
[C#] Implemented exception handling for throwing C# exceptions from C/C++ code.
A few delegate functions are available for calling which then throw the C#
exception. Use the SWIG_CSharpThrowException function from C/C++ typemaps.
See the generated wrapper code or csharphead.swg for all available exceptions.
Example:
SWIG_CSharpThrowException(SWIG_CSharpException, "exception description");
The 'throws' typemaps are also now implemented, so code is automatically
generated to convert any C++ exception into a C# System.Exception when the C++
method declares an exception specification such as:
int foo() throw(Bar);
Also any parameters that are references to a C++ class or a class passed by value
and are passed as a C# null will now throw a C# NullReferenceException.
08/29/2003: cheetah (William Fulton)
[C#] Fix to match the calling convention of all pinvoke methods so that they

08/07/2003: cheetah (William Fulton)
New commandline option -outdir <dir> to specify where the language specific

06/29/2003: cheetah (William Fulton)
[Java, C#] SF #670949 request. The destructor wrapper function name is now
configurable. A new attribute called methodname in the
javadestruct/javadestruct_derived (Java) or csdestruct/csdestruct_derived (C#)
typemaps specifies the method name. For example in Java the destructor is
wrapped by default with the delete method:
%typemap(javadestruct, methodname="delete") SWIGTYPE {...}
06/27/2003: cheetah (William Fulton)
[Java, C#] The throws attribute for adding exception classes to the throws
clause also now works with the following typemaps:
newfree
javain, javaout (Java)
csin, csout (C#)
For example, the 'AnException' will be added to the throws clause in the
proxy function:
%typemap(javaout, throws="AnException") int {
int returnValue=$jnicall;
if (returnValue==0) throw new AnException("Value must not be zero");
return returnValue;
}

06/10/2003: cheetah (William Fulton)
[C#] A number of changes have been made to remove the Java naming
that was used in the C# module.
Typemap name changes:

jtype -> imtype
jstype -> cstype
javain -> csin
javaout -> csout
javainterfaces -> csinterfaces
javabase -> csbase
javaclassmodifiers -> csclassmodifiers
javacode -> cscode
javaimports -> csimports
javaptrconstructormodifiers -> csptrconstructormodifiers
javagetcptr -> csgetcptr
javafinalize -> csfinalize
Feature name changes:
javaconst -> csconst
javamethodmodifiers -> csmethodmodifiers
Pragma changes:
pragma(java) -> pragma(csharp)
jniclassbase -> imclassbase
jniclassclassmodifiers -> imclassclassmodifiers
jniclasscode -> imclasscode
jniclassimports -> imclassimports
jniclassinterfaces -> imclassinterfaces
Special variable name changes:
$javaclassname -> $csclassname
$javainput -> $csinput
$jnicall -> $imcall
This will break SWIG interface files that use these typemaps, features
and pragmas. Please update your code or use macros for backwards
compatibility.

[MzScheme] Applied MzScheme module updates contributed by
John Lenz <jelenz@students.wisc.edu>.
- Updated mzscheme to use SWIG's common runtime type
system from common.swg.
- The Lib/mzscheme directory has been reorganized to
standardize names across the language modules:
mzscheme.i was moved to mzscheme.swg, mzscheme.swg and
mzschemedec.swg have been removed, mzrun.swg (which
contains the runtime code) has been added.
- The swig_proxy structure was renamed to swig_mz_proxy.
swig_mz_proxy now contains a pointer to a swig_type_info
structure.
- Added varin and varout typemaps for SWIGTYPE [] and
SWIGTYPE &.
- Garbage collection by calling scheme_add_finalizer() has
been added.
*** NEW FEATURE [MzScheme] ***
06/10/2003: cheetah (William Fulton)
[Java] New typemaps: javadestruct and javadestruct_derived
for the C++ destructor wrapper. The javadestruct version gets used by
classes at the top of an inheritance chain and the javadestruct_derived
version gets used by other classes.
[C#] cildispose and cildisposeoverride typemaps replaced by
csdestruct and csdestruct_derived typemaps. The delete()
method has been removed and its functionality put into these
typemaps designed for the Dispose() method.
- New typemaps csinterfaces and csinterfaces_derived replace
the javainterfaces typemap. Also fixes the peculiarity of all classes
in an inheritance chain individually deriving from the IDisposable
interface.
- New typemap csfinalize for finalizers. C++ destructors are now called
by garbage collector during finalization. Problem reported by

[Guile] Applied Guile module updates contributed by
John Lenz <jelenz@students.wisc.edu>.
- SWIG currently uses Guile's gh_ API, which is marked as
deprecated in Guile 1.6 and will be removed in Guile
1.9. This change introduces a command-line flag "-scm"
which causes SWIG to generate wrappers that use Guile's
SCM API instead; this requires Guile >= 1.6.
- The Lib/guile directory has been reorganized to
standardize names across language modules: guiledec.swg
and guile.swg have been moved into guile_gh_run.swg,
guile.i has been moved to guile_gh.swg, guile_scm.swg
and guile_scm_run.swg which contain the SCM API stuff
have been added
- ghinterface.i, which contains the defines from the gh_
functions to the scm_functions has been added
- The API for dealing with pointer objects is now
SWIG_ConvertPtr, SWIG_MustGetPtr, SWIG_NewPointerObj.
- Added varin and varout typemaps for SWIGTYPE [] and SWIGTYPE &
- Garbage collection has been added.
*** NEW FEATURE [Guile] ***
06/01/2003: cheetah (William Fulton)
Dimensionless arrays such as
int foo[] = {1, 2};
extern int bar[];
produce a warning that the variable is read-only. Depending on the target
language, this used to cause compile errors or generate a setter that
generated a runtime error. A setter cannot be automatically generated
because the array size cannot be determined by SWIG. A varin, globalin
or memberin typemap (depending on the target language) must be written
by the user.
05/29/2003: beazley
Refinement to default typemap matching and arrays. When an
array is declared like this:
int foo[4];
The default typemap now resolves to
SWIGTYPE [ANY]
If no match is found for that, it then resolves to
SWIGTYPE []
If no array dimension is specified in the original declaration,
the SWIGTYPE [] is used right away.
Note: This change has been made to resolve problems related to
arrays with and without dimensions. For example, sometimes SWIG
was generating setter functions for array variables with no dimensions
(an error). Likewise, SWIG sometimes made arrays with dimensions
read-only (also an error). This fixes the arrays_global test
problem.
05/28/2003: beazley
Fixed subtle type handling bug with references and pointers.
If you had functions like this:
typedef Foo Bar;
Foo *func1();
void func2(Bar &x);
Then func2() wouldn't accept objects returned by func1()
because of a type error. It should work now.

Build tweaks. There were a few preprocessor definitions which were
specified in the Makefile for passing on the commandline when compiling.
These are now all defined in swigconfig.h. Autoconf doesn't normally
allow installation directories to be defined in this config header file,
but an autoconf archive macro enables this. This macro along with future
autoconf macros are going to be put in the Tools/config directory.
'swig -version' now reports the target build platform.

[C# and Java] Fix to the following typemaps:
javabase, javainterfaces, javaimports, javaclassmodifiers,
javaptrconstructormodifiers, javafinalize, javagetcptr & javacode.
These are the typemaps for modifying/generating proxy classes.
Previously the typemaps would use the proxy class name and not the
C++ type, which was inconsistent with all other typemaps.
In most circumstances the proxy class name and the C++ class name/type
is the same except for classes in namespace, templated classes etc. so
this shouldn't affect most cases.

Build changes:
- Single autoconf invocation - autoconf in the Tools directory has gone.
- Libtool bootstrapped when running autogen.sh. This requires anyone
using the cvs version of SWIG to have libtool installed on their
machine. Suggest version 1.4.2 or higher, preferably the latest - 1.5.
- Automake is now used to build the runtime libraries in conjunction
with libtool.
- Runtime libraries are now successfully built as DLLs on Cygwin.
- Skipping languages is no longer just determined in the top level
makefile but in configure.in. This info is used for building
the runtime libraries and for running the examples and test-suite.
- These changes have fixed multiple build directory builds, that is
building from directories other than the top level directory.
Installation from multiple build directories also working. An initial
configure in the top level directory is no longer needed as described
in 04/02/2003 entry. A 'make distclean' will be needed before building
in a directory other than the top level directory if the autotools
have been run from this top level directory at some point, but
autoconf will tell you this. Note that 'make check' only works from
the top level directory at the moment.

04/03/2003: cheetah (William Fulton)
[C#] Improved wrapping of enums and constants. These were previously
wrapped as C# variables rather than constants. Either these are wrapped
as readonly (runtime) constants or compile time constants, depending on
the %javaconst directive (The directive is likely to change name soon).
For example wrapping:
%javaconst(0);
#define ABC 22
%javaconst(1) XYZ;
#define XYZ 33
is now:
public static readonly int ABC = examplePINVOKE.get_ABC();
public const int XYZ = 33;
04/03/2003: cheetah (William Fulton)
[Java] Global constants and enums are put in their own interface called
xxxConstants, where xxx is the module name. This is an improvement as
it is possible to derive (implement) a Java class from the xxxConstants
interface to improve the syntax; namely when wrapping:
enum {ONE=1, TWO, THREE};
accessing these from a Java class implementing xxxConstants is neater:
int number = ONE;
than the previous:
int number = xxx.ONE;
Patch submitted by Dave Dribin.
04/02/2003: cheetah (William Fulton)
Build improvements for multiple builds. This allows one to build
the SWIG executable and runtime libraries for different platforms/compilers
etc by running configure in different directories. This isn't 100% just
yet and won't be until libtool is better configured... a 'configure' and
'make distclean' needs to be run in the root directory before it all works.
For example:
$ ./configure
$ make distclean
$ mkdir config1; cd config1; ../configure CC=gcc CXX=g++; make; cd ..
$ mkdir config2; cd config2; ../configure CC=cc CXX=c++; make; cd ..
To be improved. A 'make check' does not work yet either.

[C# and Java] Added missing vararg support.
03/18/2003: mrose (Mark Rose)
Removed code related to tagging individual methods for directors.
The concept of having directors for some but not all virtual methods
of a class is deeply flawed. The %feature("nodirector") tag is also
gone.
Directors are off by default. To enable them for a class, issue
%feature("director") classname; which will create director methods
for every virtual method in the hierarchy of the class.
03/17/2003: beazley
Fixed a subtle problem with passing arguments of type function. For
example:
int foo(int x(int, int));
or
typedef int binop_t(int, int);
int foo(binop_t x);
In old versions, this would produce code that wouldn't compile. Now,
SWIG merely adds an extra pointer, making these declarations the same
as:
int foo(int (*x)(int, int));
typedef int binop_t(int, int);
int foo(binop_t *x);
Reported by Garth Bushell.
03/17/2003: mrose (Mark Rose)
Fixed the return statement for director base class calls that have no
return value.
03/15/2003: beazley
Fixed a problem with const smart-pointer wrapping. For example:
class Foo {
public:
int x;
void bar() const;
void spam();
};
class Blah {
...
const Foo *operator->();
...
};
In this case, only "x" and "bar" are visible from Blah (since application
of spam violates constness). Moreover, access to "x" is read-only.
03/15/2003: mrose (Mark Rose)
Cleaned up two signed versus unsigned comparisons in python/std_vector.i.
03/15/2003: cheetah (William Fulton)
[C#] Global variables are wrapped using properties instead of get and set methods.
Member variable wrapping bug fixes, for example wrapping pointers work now.
Typemaps are used for all variable wrapping to generate the property code.
03/13/2003: mrose (Mark Rose)
Fixed a bug in the virtual method unrolling for directors.
The order of unrolling is now from base to derived, to ensure
that the most derived implementation of a director method is
found.
Director methods for pure virtual methods now throw
DIRECTOR_PURE_VIRTUAL_EXCEPTION if _up is set.
03/12/2003: cheetah (William Fulton)

03/10/2003: beazley
Fixed problem with escape sequences in string and character constants. SWIG
wasn't parsing certain octal codes correctly.
03/07/2003: beazley
Fixed a variety of subtle preprocessor problems reported by
Sebastien Recio.
(a) Empty preprocessor values no longer generate "bad constant
value" errors. For example:
#define FOO
#define FOO BAR
(b) Macro names can now span multiple lines (technically valid,
although questionable practice). For example:
#define A_LONG_MACRO_\
NAME 42
(c) Whitespace is no longer required before certain macro values.
For example:
#define FOO"Hello"
#define BAR\
"Hello"

[Ruby] Added missing long long and unsigned long long typemaps
in the Lib/ruby/typemaps.i library file.
03/07/2003: mrose (Mark Rose)
Added Examples/python/callback to demostrate how directors can
be used to implement callbacks in Python
Added Examples/python/extend to demonstrate virtual method
calls from C++ to Python (really the same as the callback
example, just a different context).
Added four tests for very basic director functionality. These
have runtime tests under python.
The Python module now emits #define SWIG_DIRECTORS near the
top of the output file if directors are enabled. This is useful
for disabling parts of tests in target languages that don't
support directors.
03/06/2003: mrose (Mark Rose)
Added a section to Doc/Manual/Python.html on cross language
polymorphism (directors).
03/06/2003: mrose (Mark Rose)
The short-lived "-fdirectors" command line option has been
removed. To enable directors, instead use the extended %module
directive as follows:
%module(directors="1") modulename
03/06/2003: cheetah (William Fulton)
The long long typemaps have been rewritten so that they can be more
easily used with non ISO compilers, like Visual C++. For example
if you are wrapping the Windows 64 bit type __int64 the long long
typemaps can be used with %apply:
%apply long long { __int64 };
__int64 value1(__int64 x);
__int64 will now appear in the generated code instead of long long.
03/06/2003: beazley
*** DEVELOPER CHANGE ***
Swig module mutation has been changed slightly. When a language
class method wants to save node attributes, it now uses one of the
following functions:
Swig_require()
Swig_save()
The first argument to these functions is a namespace in which
saved attributes are placed. For example,this code
Node *n;
Swig_save("cDeclaration",n,"type","parms","name",NIL);
saves the attributes as "cDeclaration:type", "cDeclaration:parms",
and so forth. If necessary, a language module can refer to
old values by using this special namespace qualifier.
In addition to this, a special attribute "view" contains the name
of the last namespace used to save attributes. In the above
example, "view" would have the value "cDeclaration". The value
of "cDeclaration:view" would have the previous view and so forth.
Swig_restore(n) restores a node to the state before the last
Swig_require() or Swig_save() call.
Note: This change makes it easier for language modules to refer
to old values of attributes.
03/06/2003: mrose (Mark Rose)
Merged the cross-language polymorphism patch. When enabled, C++
"proxy" classes (called directors) are generated for each specified
C++ class. Directors pass method calls from C++ to Python, similar
to the way the usual proxy (shadow) classes pass method calls from
Python to C++. Together, these two types of proxies allow C++
classes that are extended in Python to behave just like ordinary
C++ classes and be used in C++ like native objects.
This feature is still very experimental and is disabled by default.
To enable director support, specify '-fdirectors' on the SWIG command
line or in the SWIG_FEATURES environment variable. In the interface
file, add %feature("director") to generate directors for all classes
that have virtual methods.
See http://stm.lbl.gov/~tm2/swig/ProxyDoc.html for more details.
03/03/2003: beazley
Fixed a small glitch in typemap local variable replacement. If you had
a typemap like this:
%typemap(in) type ($1_type temp) {
...
temp = ...;
...
}
and no occurrence of "$1_type" appeared in the body, then the local
variable type wouldn't be substituted.

Fixed a subtle problem with virtual method implementation
checking and typedef.
typedef int *intptr;
struct A {
virtual int *foo() = 0;

struct B : public A {
virtual intptr foo() { };
};
SWIG was treating these declarations as different even though
they are the same (via typedef).
02/25/2003: ljohnson (Lyle Johnson)
[Ruby] Added range checking for the NUM2USHRT macro, per [ 675353 ].
02/24/2003: beazley
Fixed a subtle problem with the code that determined if a class is abstract
and can be instantiated. If you had classes like this:
struct A {
virtual int foo(int) = 0;
};
struct B : virtual A {
virtual int foo(int);
};
struct C : virtual A {
};
/* Note order of base classes */
struct D : B, C { }; /* Ok */
struct E : C, B { }; /* Broken */
then SWIG determined that it could instantiate D(), but not E().
This inconsistency arose from the depth-first search of the
inheritance hierarchy to locate the implementations of virtual
methods. This problem should now be fixed---SWIG will attempt
to locate any valid implementation of a virtual method by
traversing over the entire hierarchy.
02/22/2003: cheetah (William Fulton)

11/14/2002: cheetah (William Fulton)
[Java] Handling of NULL pointers is improved. A java null object will now
be translated to and from a NULL C/C++ pointer by default. Previously when
wrapping:
class SomeClass {...};
void foo(SomeClass *s);
and it was called from Java with null:
modulename.foo(null)
a Java NullPointerException was thrown. Extra typemaps had to be written in
order to obtain a NULL pointer to pass to functions like this one. Now the
default wrapping will detect 'null' and translate it into a NULL pointer.
Also if a function returns a NULL pointer, eg:
SomeClass *bar() { return NULL; }
Then this used to be wrapped with a SomeClass proxy class holding a NULL
pointer. Now null is returned instead. These changes are subtle but useful.
The original behaviour can be obtained by using the original typemaps:
%typemap(javaout) SWIGTYPE {
return new $&javaclassname($jnicall, true);
}
%typemap(javaout) SWIGTYPE *, SWIGTYPE &, SWIGTYPE [] {
return new $javaclassname($jnicall, $owner);
}
%typemap(javagetcptr) SWIGTYPE, SWIGTYPE *, SWIGTYPE &, SWIGTYPE [] %{
protected static long getCPtr($javaclassname obj) {
return obj.swigCPtr;
}
%}

};
class abstract_bar : public abstract_foo {
public:

11/07/2002: mkoeppe
Added an experimental new module that dumps SWIG's parse
tree as (Common) Lisp s-expressions. The module is

example Lisp code that generates Foreign Function Interface
definitions for use with Kevin Rosenberg's UFFI.
*** EXPERIMENTAL NEW FEATURE ***

11/06/2002: cheetah (William Fulton)
[Java] Default primitive array handling has changed like arrays of classes.
C primitive arrays are no longer wrapped by a Java array but with a pointer
(type wrapper class). Again the changes have been made for efficiency reasons.
The original typemaps have been moved into arrays_java.i, so the original
behaviour can be obtained merely including this file:
%include "arrays_java.i"
The array support functions are no longer generated by default. They are only
generated when including this file, thus this often unused code is only
generated when specifically requiring this type of array support.
*** POTENTIAL INCOMPATIBILITY FOR JAVA MODULE ***
11/05/2002: ljohnson (Lyle Johnson)
[Ruby] Added support for nested module declarations (as was
previously added for the Perl module). So a %module directive
of the form:

module Foo
# stuff goes here
end
end

11/02/2002: cheetah (William Fulton)
[Java] Added patch submitted by Michael Cahill to remove unused parameter
warnings for the jenv and cls parameters. This patch also also allows one
to use "void" in the jni typemap for any type without code being generated
attempting to return a value.
10/29/2002: cheetah (William Fulton)
[Java] Array handling is different. Arrays of classes are no longer wrapped
with proxy arrays, eg wrapping
class X {...};
X foo[10];
used to be wrapped with these Java getters and setters:
public static void setFoo(X[] value) {...}
public static X[] getFoo() {...}
This approach is very inefficient as the entire array is copied numerous
times on each invocation of the getter or setter. These arrays are now
wrapped with a pointer so it is only possible to access the first array element
using a proxy class:
public static void setFoo(X value) {...}
public static X getFoo() {...}
Arrays of enums have also been similarly changed. This behaviour is now like the
other SWIG language's implementation and the array library should be used to
access the other elements. The original behaviour can be achieved using the
macros and typemaps in arrays_java.i, for example:
%include "arrays_java.i"
JAVA_ARRAYSOFCLASSES(X)
class X {...};
X foo[10];
*** POTENTIAL INCOMPATIBILITY FOR JAVA MODULE ***
10/29/2002: cheetah (William Fulton)
[Java] Two new typemaps javain and javaout for generating the proxy class
and type wrapper class method calls to the JNI class. The new typemaps are
really used for transforming the jstype (used in proxy class and type wrapper
classes) to the jtype (used in the JNI class) and visa versa. A javain typemap
is required whenever an in typemap is written and similarly javaout for an out
typemap. An example is probably best to show them working:
%typemap(javain) Class "Class.getCPtr($javainput)"
%typemap(javain) unsigned short "$javainput"
%typemap(javaout) Class * {
return new Class($jnicall, $owner);
}
%inline %{
class Class {};
Class * bar(Class cls, unsigned short ush) { return new Class(); };
%}
The generated proxy code is then:
public static Class bar(Class cls, int ush) {
return new Class(exampleJNI.bar(Class.getCPtr(cls), ush), false);
}
Some new special variables have been introduced in order to use these typemaps.
Here $javainput has been replaced by 'cls' and 'ush'. $jnicall has been replaced by
the native method call, 'exampleJNI.bar(...)' and $owner has been replaced by 'false'.
$javainput is analogous to the $input special variable. It is replaced by the parameter name.
$jnicall is analogous to $action in %exception. It is replaced by the call to the native
method in the JNI class.
$owner is replaced by either true if %newobject has been used otherwise false.
The java.swg file contains default javain and javout typemaps which will produce the same code
as previously. This change is only of concern to those who have written their own typemaps as
you will then most likely have to write your own javain and javaout typemaps.
The javaout typemap also makes it possible to use a Java downcast to be used on abstract
proxy base classes. See the Java documentation on dynamic_cast.

[Java] Some error checking added:
1) OutOfMemoryException check in the char * typemaps.
2) As SWIG treats pointers, references and passing by value all the

09/15/2002: beazley
Deprecation of the "ignore" typemap. The "ignore" typemap has
been deprecated in favor of a generalization of the "in" typemap.
To ignore an argument, use something like this instead:
%typemap(in,numinputs=0) int *output (int temp) {
$1 = &temp;
}
This change fixes a number of subtle bugs related to the interaction
of the "in" and "ignore" typemaps (which were supposed to be
mutually exclusive).
The use of the numinputs argument is reserved for future expansion.
Currently, values >1 will generate an error. However, future
releases of SWIG may utilize that to support multi-input typemaps.
%typemap(ignore) still works, but generates a warning message and is
translated to %typemap(in,numinputs=0).

Fixed segmentation fault for unnamed structures. For example:
typedef struct {
} *blah;
Reported by Roger Gibson.
Note: we might be able to generate wrappers in special cases.
09/13/2002: beazley
Minor modification to generated wrapper functions. Pointer arguments are now
always set to an initial value of 0. Simplifies typemap writing and cleanup
code (since you can rely on zero-value initialization). This also greatly
reduces the need to ever write an "arginit" typemap.
09/12/2002: beazley
Minor enhancement to smart-pointer support. If operator->()
is part of an ignored base class like this,
%ignore Bar;
class Foo {
public:
int blah();
};
class Bar { /* Ignored */
public:
...
Foo *operator->();
...
};
class Spam : public Bar { };
then methods from Foo are still available. For example,
>>> s = Spam()
>>> s.blah()
0
>>>
The only catch is that the operator->() itself is not available
(since it wasn't wrapped). Therefore, there won't be any
__deref__() operation unless it is explicitly added to Spam
(either using %extend or just placing operator->() in the
definition of Spam).

SWIG-1.3.15 released.
Version 1.3.15 (September 9, 2002)
==================================
09/09/2002: beazley
Fixed nasty runtime type checking bug with subtypes and inheritance
and templates.
09/09/2002: cheetah (William Fulton)
[Java] Java exception classes for a method's throws clause can be generated by
specifying them in a comma separated list in the throws attribute in any one
of the following typemaps: in, out, check, freearg, argout and throws. A classic
example would be to convert C++ exceptions into a standard Java exception:
%typemap(throws, throws="java.io.IOException") file_exception {
jclass excep = jenv->FindClass("java/io/IOException");
if (excep)
jenv->ThrowNew(excep, $1.what());
return $null; // or use SWIG_fail
}
class file_exception {...};
void open(const char *filename) throw(file_exception);
The Java method will then be declared with a throws clause:
public static void open(String filename) throws java.io.IOException {...}
09/08/2002: mkoeppe
* [Guile] Improved the documentation system. The arglist no
longer gets cluttered with type specification, making it
more readable. (Also the ILISP function C-u M-x
`arglist-lisp' RET works better this way.) The types of
arguments are explained in an extra sentence after the
arglist.
There are now two documentation-related typemap arguments:
%typemap(in, doc="$NAME is a vector of integers",
arglist="$name") int *VECTOR { ... }
The "arglist" texts of all arguments of a function make up
its arglist in the documentation. The "doc" texts of all
arguments are collected to make a sentence that describes
the types of the arguments. Reasonable defaults are
provided.
As usual, $name is substituted by the name of the
argument. The new typemap variable $NAME is like $name,
but marked-up as a variable. This means that it is
upper-cased; in TeXinfo mode ("-procdocformat texinfo") it
comes out as @var{name}.
The directives %values_as_list, %values_as_vector,
%multiple_values now also have an effect on the
documentation. (This is achieved via the new pragmas
return_nothing_doc, return_one_doc, return_multi_doc.)
Documentation has also improved for variables that are
wrapped as procedures-with-setters (command-line switch
"-emit-setters").
* [Guile] Emit constants as _immutable_ variables. (This
was broken recently.)
09/07/2002: mkoeppe
[Guile] Updated the typemaps in list-vector.i.
09/07/2002: mkoeppe
Short-circuit the typechecks for overloaded functions.

09/06/2002: cheetah (William Fulton)
[Java] Solution for [ 596413 ]
New typemap so that the Java proxy classes and type wrapper classes
wrapper constructor modifier can be tailored by users. The default value is
protected. Normally SWIG generates a constructor like this which can only
be accessed within one package:
protected Bar(long cPtr, boolean cMemoryOwn) {
...
}
If you are using SWIG across multiple packages or want to use this constructor
anyway, it can now be accessed outside the package. To modify use for example:
%typemap(javaptrconstructormodifiers) SWIGTYPE "public"
to change to public for all proxy classes and similarly for all type wrapper classes:
%typemap(javaptrconstructormodifiers) SWIGTYPE, SWIGTYPE *, SWIGTYPE &, SWIGTYPE [] "public"
09/06/2002: cheetah (William Fulton)
[Java] Added throws typemaps for the Java module. C++ exceptions get converted into

Better reference support.
Functions that want a void** can take a NULL by reference and
the void* will be made for you and then passed-by-reference
Also all integer-class native types can be passed by reference
where an int* or int& etc is needed
09/03/2002: beazley
Changed the evaluation order of preprocessor macro arguments.
Arguments are now expanded by the preprocessor *before* they
are passed to macro expansion. This fixes a subtle expansion
bug reported by Anthony Heading.
09/03/2002: beazley
Fixed the file include order (again, apparently). See 2/27/99.
09/02/2002: beazley
[Perl] Better exception handling support. Since Perl error handling
relies on setjmp/longjmp, wrapper functions have been modified slightly
to provide an extra block scope:
XS(foo) {
char _swigmsg[SWIG_MAX_ERRMSG] = "";
const char *_swigerr = _swigmsg;
{
/* Normal wrapper function here */
...
SWIG_croak("An error occurred\n");
...
XSRETURN(argvi); /* Successful return */
fail:
/* cleanup code */
}
croak(_swig_err);
}
The macro SWIG_croak(x) sets the value of _swigerr to x and
executes a "goto fail". The whole wrapper function is enclosed
block scope to provide proper cleanup of C++ objects. Since
croak executes a longjmp(), there is no way to properly reclaim
resources if this executes in the same scope as the wrapper
function.
The _swigmsg[] variable is normally unused, but can be used
to store small error messages using sprintf or snprintf. It
has a capacity of at least 256 bytes (SWIG_MAX_ERRMSG).
09/02/2002: beazley
[Tcl] Added better support for exceptions. Instead of returning TCL_ERROR,
use the macro SWIG_fail to return with an error. This ensures that
arguments are properly cleaned up. Exception specifiers are now
handled by default.
09/02/2002: ljohnson (Lyle Johnson)
[Ruby] The type-checking system for the Ruby module has had a flaw
in that some types which should be considered equivalent
weren't. This bug was best demonstrated by the inherit_missing.i
test suite case, which defines a base class "Foo" that is
subclassed by "Bar". The "Foo" class isn't actually wrapped (i.e.
it's not directly accessible from Ruby) but we'd still like to be
able to pass "Bar" instances to functions expecting Foos and have
that work; it wasn't. The revised implementation (similar to that
used for some other language modules) adds a new instance variable
(__swigtype__) to each object that indicates its SWIG type;
that is, each "Bar" instance will now have a string instance
variable called "__swigtype__" whose value is "_p_Bar".
Unless developers were taking advantage of this low-level
implementation detail, they shouldn't notice any compatibility
problems; nevertheless, I'm marking it as a "potential
incompatibility".

[Ruby] Added the "%mixin" directive, which allows the user to
specify a comma-separated list of module names to mix-in to a
class. So, for example, if you'd like to specify that Ruby's
Enumerable module should be mixed-in to your class Foo, you'd
write:
%mixin Foo "Enumerable";
or to specify that the modules Fee, Fie and Fo should be mixed
in to Foo:
%mixin Foo "Fee,Fie,Fo";

Fixed [ 600132 ] Default argument with namespace.
Reported by Shibukawa Yoshiki.
08/24/2002: beazley
Automatic C++ exception handling enabled for all language modules. This is
pretty simple. If you have a class like this:
class Foo {
};
class Bar {
public:
void blah() throw(Foo);
}
then the generated wrapper code looks like this:
wrap_Bar_blah() {
...
try {
arg1->blah();
}
catch (Foo &_e) {
/* "throw" typemap code inserted. $1 = _e */
}
catch (...) {
throw;
}
}
The "throw" typemap can be used to raise an error in the target
language. It can do anything. Here is a very simple example:
%typemap("throw") Foo {
PyErr_SetString(PyExc_RuntimeError, "Foo exception");
return NULL;
}
To make this work in each language module, simply define a few default
"throw" typemaps for SWIGTYPE, SWIGTYPE *, int, const char *, and a
few common exception types. That's all there is to it.
Automatic exception handling can be disabled using -noexcept or
setting the NoExcept global variable to 1.
*** NEW FEATURE ***
08/23/2002: beazley
[ Python ]
Automatic translation of C++ exception specifications into error handling code.
For example:
class Foo {
};
class Bar {
public:
void blah() throw(Foo);
}
In this case, Foo is wrapped as a classic-style class (compatible
with exception handling). Furthermore, you can write Python code
like this:
b = Bar()
try:
b.blah();
except Foo,e: # Note use of exception class here!
# Handle Foo error
...
The object "e" in the exception handler is just a wrapped Foo
object. Access it like a normal object.
If an exception is not wrapped as a class, a RuntimeError
exception is raised. The argument to this exception is
the exception object. For example:
class Bar {
public:
void blah() throw(int);
}
b = Bar()
try:
b.blah();
except RuntimeError,e:
print e.args[0] # Integer exception value
Comments:
- If a class is used as an exception, it *must* be wrapped
as a Python classic-style class (new classes don't work).
- Automatic exception handling is compatible with %exception.
- Use -noexcept to turn off this feature.
- The newly introduced "throw" typemap is used to raise
Python errors (naturally).
*** EXPERIMENTAL NEW FEATURE ***
08/23/2002: beazley
Information from throw() specifiers is now stored in the parse
tree. For example:
class Foo {
public:
int blah() throw(spam,bar);
}
The stored information is fully corrected for namespaces and works
with templates. Uses will follow.
08/22/2002: beazley
Exception handling code is no longer applied to member access
function. For example, in this code
%exception {
try {
$action
} catch(whatever) {
...
}
}
class Foo {
public:
int x;
...
}
The exception handling code is not applied to accessor functions
for Foo::x. This should reduce the amount of extra code
generated.
Caveat: Exception handling code *is* used when attributes are
accessed through a smart-pointer or a synthesized attributed
added with %extend is used.
08/22/2002: beazley
Made more patches to hopefully eliminate problems when compiling SWIG
as a 64-bit executable.
08/22/2002: beazley
Fixed a bug with const reference members, variables, and static members.
For example:
class Foo {
public:
static const int &ref;
};
SWIG was trying to generate "set" functions which wouldn't compile.
08/21/2002: beazley
Made the warning message for "Class X might abstract" off by default.
Enable with -Wall.
08/21/2002: beazley
Refined handling of const and non-const overloaded methods. If
a class defines a method like this:
class Foo {
public:
int bar(int);
int bar(int) const;
}
Then the non-const method is *always* selected in overloading and
the const method silently discarded. If running with -Wall, a warning
message will be generated.
08/19/2002: beazley
Better support for using declarations and inheritance. Consider this:
class Foo {
public:
int blah(int x);
};
class Bar {
public:
double blah(double x);
};
class FooBar : public Foo, public Bar {
public:
char *blah(char *x);
using Foo::blah;
using Bar::blah;
};
Now SWIG wraps FooBar::blah as an overloaded method that uses all
accessible versions of blah(). See section 15.2.2 in Stroustrup, 3rd Ed.
SWIG also supports access change through using declarations. For example:
class Foo {
protected:
int x;
int blah(int x);
};
class Bar : public Foo {
public:
using Foo::x;
using Foo::blah;
};
Caveat: SWIG does not actually check to see if declarations imported
via 'using' are in the inheritance hierarchy. If this occurs, the
wrapper code won't compile anyways---not sure it's worth worrying about.
08/18/2002: beazley
Modified overloading dispatch to not include nodes with an "error" attribute.
A language module can set this if a node couldn't be wrapped and you don't want
it included in the dispatch function.
08/18/2002: beazley
Enhancement to overloaded function dispatch. The dispatcher is now aware of
inheritance relationships. For example:
class Foo { };
class Bar : public Foo { };
void spam(Foo *f);
void spam(Bar *b);
In this case, the dispatcher re-orders the functions so that spam(Bar *b) is
checked first---it is more specific than spam(Foo *f).
08/17/2002: beazley
Added -Werror command line option. If supplied, warning messages are treated
as errors and SWIG will return a non-zero exit code.
08/17/2002: beazley
Fixed [ 596135 ] Typedef of reference can't compile. For example:
typedef int &IntRef;
void foo(IntRef i);
SWIG-1.3.14 generated code that wouldn't compile.
Version 1.3.14 (August 12, 2002)
================================
08/11/2002: mmatus
Static const members initialized during declaration, and
only them, ie:
struct A
{
static const int a = 1 ; // this one
static const int b; // not this one
};
are emitted like constants (equivalent to enums or
explicit %constant).
This is because they cannot be added directly to 'cvar'
since they lack the needed reference (well, you can force
them to have a real reference, but in an ugly way which
goes completely again the original purpose of initialize
them during declaration, you also have to deal with extra
linking matters, and it take a while to figure out what is
the problem and how to solve it).
Please test it with your preferred target language, and
not only the code generation, but really run the example
in the test-suite (static-const-member-2.i) because the
problem and the solution cannot be "fully" appreciated
until you try to load the module and run it.
In some target languages (python specially), this can
produces a difference in the way that the static constant
members 'a' and 'b' are internally wrapped. Hopefully,
they still can be accessed in the same way.
08/11/2002: mmatus
[python] Now static const members can be accessed in a more
natural way, ie, if you have
struct A
{
typedef unsigned int viewflags;
static const viewflags forward_field = 0;
static const viewflags backward_field;
};
now you can do:
print A.backward_field
and also
a = A()
print a.forward_field
Note that if the static const members don't have an
initializer (like backward_field), still you can access
them in the same way in the python side, but the
implementation is a quite different: backward_field will
still appear in the cvar entity, and also, you are
responsible to initialize it in some code unit, and link it
properly. forward_field, by the other hand, will not
appear in the cvar entity but only as a A member, similar
to what happen with enum or %constant members.
08/11/2002: mmatus
[python] Common code in the __setattr__/__getattr__ now
goes to two "free" methods at the beginning of the proxy
file, from where each class use it. This change reduces
the size of the proxy file, specially if you wrap a lot of
small classes in one module (up to 33% in some cases),
making it faster to load too.
08/09/2002: beazley
[Perl5] If a function that returns char * returns NULL,
undef is returned to the Perl interpreter.
08/09/2002: beazley
Fix to conversion operators and namespaces. For example:
namespace ns {
struct Foo { };
struct Bar {
operator Foo*();
};
}
In the wrapper code, SWIG was using ->operator Foo*()
when it should have been using ->operator ns::Foo*().
Note: if using %rename with a conversion operator, you
might have to do this:
%rename(toFooPtr) ns::operator ns::Foo*();
// ^^^^ note extra qualifier
namespace ns {
...
08/09/2002: beazley
[Python] Minor enhancement to 'const' variable declarations.
Normally const declarations are wrapped as read-only variables
accessible only through the cvar attribute (see SWIG.html for
a discussion of why). However, in many programs, "const"
declarations may just be constants---making the cvar. access
awkward. To fix this, "const" declarations are now available
both through cvar. and as a simple name. For example:
const int FOO = 42;
In Python:
>>> print example.cvar.FOO
42
>>> print example.FOO
42
Note: There are cases where the value of a "const" variable
might change. For example:
char *const BAR = "Hello World";
In this case, the pointer itself can not change, but the
data being pointed to could be modified. In these situations,
cvar.BAR should be accessed to obtained the current value.
08/08/2002: beazley
[Python] Fixed generation of the proxy code (.py files) to more
closely follow the order of declarations as they appear in
the .i file. In the past, all of the class wrappers appeared
first, followed by function stubs, inserted Python code, and
other details.
08/08/2002: cheetah (William Fulton)
[Java] Proxy method _delete() changed to delete(). There shouldn't ever
be a wrapped function called delete() as it is a C++ keyword and there
is no such thing as a member function in C.
*** POTENTIAL INCOMPATIBILITY FOR JAVA MODULE ***
Backwards compatibility can be achieved by adding the function back in
for all proxy classes:
%typemap(javacode) SWIGTYPE %{
public void _delete() {
delete();
}
%}
Java backwards compatibility summary
------------------------------------
There are a number of changes that have been made in improving the Java module
for ver 1.3.14. If at all possible change your code to take advantages of the
improvements. If you were using proxy classes you may not notice any backwards
compatibility issues. Here is an example which will help with most backwards
compatibility problems where it is not possible to modify the code that uses
the generated output:
Replace:
%module modulename
With:
%module (jniclassname="modulename") modulename;
%typemap(javacode) SWIGTYPE %{
public long getCPtr$javaclassname() {
return swigCPtr;
}
public void _delete() {
delete();
}
%}
%pragma(java) jniclassclassmodifiers="public";
The proxy constructors that took parameters (long cPtr, boolean cMemoryOwn)
were public and are now protected. If you were making use of these then you'll
have to modify your code and the best solution would be to use the new type
wrapper classes.
The other main areas are the pragmas and global variable wrapping. Replace
the pragmas with one of the new directives or typemaps mentioned below and use
%rename on the variables.
If you were not using proxy classes, you will have to define a jstype typemap
as well as a jtype typemap.
08/08/2002: cheetah (William Fulton)
[Java] Fix for wrapping two dimension array variables.
08/07/2002: beazley
[Python,Tcl]
Object management now has a much better sense of ownership.
Ownership bits is changed whenever an object is stored in a
global variable or structure member. For example:
struct Foo {
int val;
Foo *next;
};
Now in Python
>>> f = Foo()
>>> f.thisown
1
>>> g = Foo()
>>> g.next = f # Assign a pointer
>>> f.thisown # Notice ownership change
0
>>>
This scheme is mostly a conservative heuristic designed to
provide segmentation faults. It could cause a memory leak
if ownership is changed unnecessarily. In this case, you can
either write a typemap (that doesn't change ownership), or
manually set the thisown attribute back to 1.
08/07/2002: beazley
[Tcl] Major usability improvements to the object interface.
Suppose you had code like this:
struct Foo {
int x;
int spam();
};
void blah(Foo *f);
In past versions of SWIG, you could create objects and use
them like this:
% Foo f
% f configure -x 3
% f spam
37
The only problem is that if you tried to call blah(), it didn't
work:
% blah f
Type Error. Expected _p_Foo
%
Instead, you had to do this:
% blah [f cget -this]
SWIG now automatically extracts the -this pointer, avoiding this
problem. This means that saying "blah f" is perfectly legal and
everything will still work normally.
Caveat: Since pointer strings start with a leading underscore (_),
don't use this in object names. For example:
% Foo _f
% blah _f # Potential crash
Objects now have a -thisown attribute that shows the ownership.
This builds upon the CHANGES 11/24/2001 entry.

from 'modulename' to modulenameModule.
08/01/2002: beazley
Fixed problem with file include order. Language specific

property design pattern like member variables always have. This means if you are
wrapping a variable called foo, the getter is called getFoo() and the setter is
called setFoo(). Before the recent changes to the Java module the getters and
setters were called get_foo() and set_foo(). If you really want the original
function names use the %rename directive like this: %rename(_foo) Foo;

Fixed casting problem with multiple inheritance. If you had this,
class foo {};
class bar : public foo {};
class baz : public foo {};
class spam : public bar, public baz {};
then the wrappers wouldn't compile due to an ambiguous cast.
Reported by Art Yerkes.
07/30/2002: cheetah (William Fulton)
[Java] Due to new static typechecking all pointers held in a Java long are part of
the internal workings and this pointer value in the Java long has become abstracted
data. The type wrapper constructor and getCPtr() methods are as such protected.
If you need to mess around with pointers from Java or for example create a proxy
class or type wrapper class around a null pointer, add a function/constructor
to do so with the %javacode typemap. You can also make getCPtr() public again with
the %javagetcptr typemap.
07/30/2002: cheetah (William Fulton)
[Java] Fixes for %typemap(ignore). In particular when ignoring the last parameter
in a function. Also for all parameters in constructors. These mods have also fixed
multi-argument typemaps for proxy classes - SF 581791.
07/30/2002: cheetah (William Fulton)
[Java] %newobject (replacement for %new) now implemented for Java.
07/29/2002: beazley
Fixed problem with typemap copies, %apply, and %clear inside
C++ namespaces.
07/28/2002: cheetah (William Fulton)
[Java] The JNI class now has package access as the class modifier
has been changed from "public" to nothing. This has been done
as this class is now more for the internal workings of SWIG since the module
class has static type checking for all types.
*** POTENTIAL INCOMPATIBILITY FOR JAVA MODULE ***
Backwards compatibility can be achieved by using the %jniclassclassmodifier
pragma to change it back to "public".
07/28/2002: cheetah (William Fulton)
[Java] Proxy/Shadow classes are generated by default. The -proxy and
-shadow command line options are deprecated. If you want to use the
low-level functional interface then use the new -noproxy commandline option.
*** POTENTIAL INCOMPATIBILITY FOR JAVA MODULE ***
07/28/2002: cheetah (William Fulton)
[Java] Remaining pragmas shakeup. These were the remaining pragmas and their
new names where changed:
modulebase
modulecode
moduleclassmodifiers
moduleimport => moduleimports
moduleinterface => moduleinterfaces
The moduleimports works slightly differently to how the moduleimport pragma worked.
Now it actually takes code which gets placed before the class definition so the
whole import statement has to be given, for example:
%pragma(java) moduleimports=%{
import java.io.*;
import java.math.*;
%}
The moduleinterfaces is slightly different to the old moduleinterface in that if
more than one interface is required they must be comma separated in one use of
the pragma, for example:
%pragma(java) moduleinterfaces="Serializable, MyInterface"
These last two pragmas are consistent with the javainterfaces and javaimports
typemap.
A similar set of pragmas has been introduced, namely:
jniclassbase
jniclasscode
jniclassclassmodifiers
jniclassimport
jniclassinterface
These work in the same way as their module counterparts. Note that previously
the moduleXXX pragmas worked on the old module class which is now called the
JNI class (the class with the native functions). The jniclassXXX pragmas now
work on the new module class (the class that has all the global functions and
global variable getters and setters when using proxy classes, plus all other
remaining functions when using the low-level procedural interface).
In summary the contents of the pragmas make up a class like this:
<jniclassimports>
<jniclassmodifiers> class modulename extends <jniclassbase> implements <jniclassinterfaces> {
<jniclasscode>
... SWIG generated functions ...
}
}
*** POTENTIAL INCOMPATIBILITY FOR JAVA MODULE ***
07/28/2002: cheetah (William Fulton)
[Java] Deprecated modulemethodmodifiers pragma and replaced with
a better %feature based directive called %javamethodmodifiers.
A useful example would be for synchronisation in multi-threaded apps:
%javamethodmodifiers foo(int a) "public synchronized";
Changes this function from the default ("public") to "public synchronized".
*** POTENTIAL INCOMPATIBILITY FOR JAVA MODULE ***
07/26/2002: beazley
Several directives now allow optional configuration parameters.
These include:
%module(name="value", name="value", ...) modulename
%import(name="value", ...) "filename.i"
%extend(name="value", ...) classname {
...
}
These currently have no effect and are reserved for
future expansion.
07/26/2002: beazley
Enhancements to smart-pointer handling. SWIG only provides
extra support for a smart-pointer if operator->() returns
a proper pointer. For example:
Foo *operator->();
If operator->() returns an object by value or reference,
then SWIG examines the returned object to see if it also
implements operator->(). If so, SWIG chases operator->()
until it can find one that returns a pointer. This allows
cases like this to work:
class Foo {
public:
void blah();
};
class Bar {
...
Foo *operator->();
...
};
class Spam {
...
Bar operator->();
...
};
For example:
>>> s = Spam()
>>> s.blah() # Invokes Foo::blah()
The s.blah() call actually invokes:
((s.operator->()).operator->())->blah();
07/26/2002: beazley
Fixed a bug with typedef and references. For example:
typedef Foo & FooRef;
FooRef blah();
Previous versions of SWIG generated code that wouldn't
compile.
07/25/2002: beazley
Wrapping of static methods has been improved in proxy classes. In older
versions of SWIG, if you had this:
class Foo {
public:
static void bar();
};
The static method was only available as a function Foo_bar(). For example:
>>> Foo_bar()
Now, the static method can also be invoked through an instance like this:
>>> f = Foo()
>>> f.bar() # Invokes static method
This works with all versions of Python. Additionally, for Python-2.2,
the static method can be invoked as:
>>> Foo.bar()
The old-style function is still support for backwards compatibility. If
you care about making your code across different versions of Python,
either use Foo_bar() or access the method through an instance.
07/25/2002: beazley
Changes to the Python module. Proxy classes now utilize new Python-2.2
features including properties and static methods. However, these features
are supported in a way that provides backwards compatibility with older
Python versions. In other words, proxy classes work with all versions
of Python and only use new features when running on Python-2.2.
07/25/2002: beazley
Modified %extend so that overloaded methods can be added. For example:
%extend Foo {
void bar(int x) { };
void bar(char *s) { };
...
}
This works with both C++ *and* C.
07/24/2002: cheetah (William Fulton)
[Java] More new typemaps so that the Java proxy classes and type wrapper classes
can be further tailored by users. These are the default code for generating the
finalize() methods (proxy classes only) and the getCPtr() methods for proxy
classes and type wrapper classes:
%typemap(javafinalize) SWIGTYPE %{
protected void finalize() {
_delete();
}
%}
%typemap(javagetcptr) SWIGTYPE, SWIGTYPE *, SWIGTYPE &, SWIGTYPE [] %{
public static long getCPtr($javaclassname obj) {
return obj.swigCPtr;
}
%}
The javagetcptr typemap will enable users to handle Java null by overriding
this typemap - a requested feature.
The -nofinalize commandline option has been deprecated. The javafinalize
typemap is more powerful as it will allow the removal of the finalize methods
for all or any one or more particular proxy class.
07/23/2002: cheetah (William Fulton)
[Java] The getCPtrXXX() function has been changed to a static function and
is now of the form:
protected static long getCPtr(XXX obj) {...}
This is a requested change which will allow Java null pointers to be used as null
can be passed in for obj. However, to achieve this the appropriate code must be
written using the new javagetcptr typemap directive.
*** POTENTIAL INCOMPATIBILITY FOR JAVA MODULE ***
Backwards compatibility can be achieved by adding this function back in using the
new javacode typemap:
%typemap(javacode) SWIGTYPE %{
// SWIG-1.3.12 and SWIG-1.3.13
public long getCPtr$javaclassname() {
return swigCPtr;
}
// SWIG-1.3.11 and earlier
public long getCPtr() {
return swigCPtr;
}
%}
07/23/2002: cheetah (William Fulton)
[Java] New directive to control constant code generation - %javaconst.
The default handling for handling constants is to get the value through
a JNI call, eg
#define YELLOW 5
#define BIG 1234LL
results in:
public final static int YELLOW = modulename.get_YELLOW();
public final static long BIG = modulename.get_BIG();
Earlier versions of the Java module initialised the value using the C value:
public final static int YELLOW = 5;
public final static long BIG = 1234LL;
This works in most cases, but the value for BIG won't compile as 1234LL is not
valid Java code and this is one of the reasons why the default is now to get the
values through a JNI call. The side effect is that these 'constants' cannot be used
in switch statements. The %javaconst directive allows one to specify the
way the constant value is initialised and works like other %feature
directives, eg
%javaconst(0); // all constants from this point on are initialised using the C value
%javaconst(1) BIG; // just BIG initialised using JNI call (must be parsed before BIG is defined)
07/23/2002: beazley
*** IMPORTANT CHANGES TO THE PYTHON MODULE ***
(1) The Python module now enables shadow/proxy classes by default.
This means that two files are always created by SWIG. For
instance, if you have this:
// file: foo.i
%module foo
...
Then swig generates two files "foo_wrap.c" and "foo.py".
(2) The name of the low-level C extension module has been changed
to start with a leading underscore. This means that you have
to compile the module as follows:
$ cc -c -I/usr/local/include/python2.2 foo_wrap.c
$ cc -shared foo_wrap.o $(OBJS) -o _foo.so
^^^^
note extra underscore
This naming scheme is consistent with other Python modules that
utilize extension code. For instance, the socket module consists
of "_socket.so" and "socket.py". In previous versions of SWIG,
the shared object file was named "foocmodule.so".
(3) A new directive can be used to insert Python code into
the corresponding .py file. For example:
%pythoncode %{
def foo():
print "Hello World"
%}
This directive allows you to create modules as a mix of C and Python.
Python code is seamlessly added to the module.
(4) The -shadow command line option is deprecated. This is turned on
by default.
(5) To disable the generation of the extra python file, use the "-noproxy"
command line option.
*** POTENTIAL INCOMPATIBILITY ***
This change will likely break the build environment of projects that
utilize shadow classes. To fix this, you probably only need to
change the name of the target .so file. For example, if you have
Makefile information like this:
TARGET = examplecmodule.so
Just change it to:
TARGET = _example.so
*** DOCUMENTATION UPDATE ***
The file Doc/Manual/Python.html has been updated to describe these changes.
07/23/2002: beazley
Added -noextern option. If supplied, SWIG will not generate
extra extern declarations. This is sometimes an issue on
non-unix platforms.
07/23/2002: beazley
Added a warning for ignored friend functions.
07/23/2002: beazley
Fixed [ 574498 ] -proxy and %include "pointer.i" clash.
Reported by David Creasy.
07/23/2002: beazley
Fixed [ 576103 ] global destruction warning with shadow.
Perl extensions should no longer report the warning
"Use of uninitialized value during global destruction."
when running with "perl -w". Reported by
Brett Williams.
07/23/2002: beazley
In C++ mode, SWIG now always defines namespace std. By default,
it's empty. However, this will silence errors from programs
that include statements such as "using namespace std;".
This fixes Bug [ 584017 ] using namespace std generates error.
Reported by Joseph Winston.
07/22/2002: beazley
Added a new warning message for %apply. If you use %apply but no typemaps
are defined, you will get a warning message. This should help with
problems like this:
%apply char *OUTPUT { ... };
In old versions of SWIG, this silently did nothing. Now you get an error like this:
file:line. Warning. Can't apply (char *OUTPUT). No typemaps are defined.
07/22/2002: cheetah (William Fulton)
[Java] Started Java pragma deprecation. Replacements use %typemap based
directives and enable proxy classes and the new type wrapper classes to be
tailored in various ways. These are the new typemaps:
%typemap(javabase) - base (extends) for Java class
%typemap(javaclassmodifiers) - class modifiers for the Java class: default is "public"
%typemap(javacode) - java code is copied verbatim to the Java class
%typemap(javaimports) - import statements for Java class
%typemap(javainterfaces) - interfaces (extends) for Java class
And these are the %pragma directives being deprecated:
allshadowbase
allshadowclassmodifiers
allshadowcode
allshadowimport
allshadowinterface
shadowbase
shadowclassmodifiers
shadowcode
shadowimport
shadowinterface
Note that it is possible to target a particular proxy class:
%typemap(javaimports) Foo "import java.util.*"
or a particular type wrapper class:
%typemap(javaimports) double* "import java.math.*"
Note that $javaclassname in these typemaps are substituted with either the proxy
classname when using proxy classes or the SWIGTYPE class name.
07/18/2002: cheetah (William Fulton)
[Java] Java module overhaul to implement static type checking of all
types.
1) Changes when using Java Proxy classes
----------------------------------------
Previously when wrapping global functions:
class SomeClass{};
void foo(SomeClass* s);
SomeClass* bar();
The native method prototypes used a long for pointers and looked like this:
public class modulename {
...
public final static native void foo(long jarg1);
public final static native long bar();
}
and unlike member functions of a C++ class there was no wrapper around the native calls
to make the use of them more user friendly. They would be used from Java like this:
SomeClass s = new SomeClass(modulename.bar(), false);
modulename.foo(s.getCPtrSomeClass());
Note that the following will have the same effect, but then it would not have
been possible to call any proxy member functions in SomeClass:
long s = modulename.bar();
modulename.foo(s);
Now wrapper functions are generated:
public class modulename {
public static void foo(SomeClass s) {
// calls the native function
}
public static SomeClass bar() {
// calls the native function
}
}
Which means these functions can now be used more naturally with proxy classes:
SomeClass s = modulename.bar();
modulename.foo(s);
2) Changes when not using Java Proxy classes
--------------------------------------------
The so called low-level interface was rather low-level indeed. The
new static type checking implementation makes it less so but it remains a
functional interface to the C/C++ world. Proxy classes are the obvious way to use
SWIG generated code, but for those who want a functional interface all non-primitive
types now have a simple Java class wrapper around the C/C++ type. Pointers and
references to primitive types are also wrapped by type wrapper classes. The type
wrapper classnames are based on the SWIG descriptors used by the other language
modules. For example:
C/C++ type Java type wrapper class name
---------- ----------------------------
int* SWIGTYPE_p_int
double** SWIGTYPE_p_p_double
SomeClass* SWIGTYPE_p_SomeClass
SomeClass& SWIGTYPE_p_SomeClass
SomeClass SWIGTYPE_p_SomeClass
Note that everything wrapped by SWIG is accessed via a pointer even when wrapping
functions that pass by value or reference. So the previous example would now be
used like this:
SWIGTYPE_p_SomeClass s = example.bar();
example.foo(s);
Note that typedefs that SWIG knows about are resolved, so that if one has
class Foo{};
typedef Foo Bar;
then any use of Bar will require one to use SWIGTYPE_p_Foo;
Some considerations:
Make sure you make a firm decision to use either proxy classes or the functional
interface early on as the classnames are different.
3) Pointers and non-parsed types
--------------------------------
Sometimes SWIG cannot generate a proxy class. This occurs when the definition of
a type is not parsed by SWIG, but is then used as a variable or a parameter.
For example,
void foo(Snazzy sds);
If SWIG has not parsed Snazzy it handles it simply as a pointer to a Snazzy.
The Java module gives it a type wrapper class around the pointer and calls it
SWIGTYPE_p_Snazzy. In other words it handles it in the same manner as types are
handled in the low-level functional interface. This approach is used for all
non-proxy classes, eg all pointer to pointers and pointers to primitive types.
4) Backwards compatibility
-----------------------
Backwards compatibility is not an issue if you have been using proxy classes and
no global variables/functions. Otherwise some changes will have to be made.
The native methods still exist but they are now in a JNI class, which is called
modulenameJNI. As this class is really part of the internal workings,
it should not be required so the class has become protected. Some pragmas/directives
will hopefully be added to help with backwards compatibility.
*** POTENTIAL INCOMPATIBILITY FOR JAVA MODULE ***
07/18/2002: beazley
Modified wrapping of uninstantiated templates returned by
value. Just to be safe, they are now wrapped by SwigValueWrapper<>
just in case they don't define a default constructor. This
would be used if you had code like this
Foo<int> blah();
void moreblah(Foo<int> x);
but you didn't instantiate Foo<int> using %template.
We should probably add a warning for this.
07/17/2002: beazley
Added an error check to detect shadowed template paramaters.
For example:
template<class T> class Foo {
public:
int T;
};
This results in an error, not a warning. This warning is
also needed to fix some rather insidious problems like
this:
struct T {
int blah;
};
template<class T> class Foo {
public:
typedef T Traits; // Which T is this????
};
In this case, the template parameter T shadows the outer
structure (which is what you want).
07/16/2002: beazley
Improved support for templates with integer arguments. SWIG is
much more aware of situations such as this:
const int Size = 100;
%template(Foo100) Foo<100>;
void bar(Foo<Size> *x); // Knows that Foo<Size> is the same as Foo<100>;
07/15/2002: beazley
Fixed bug with %feature/%ignore/%rename and namespaces.
For example:
%ignore Foo::Bar
namespace Foo {
class Bar {
...
};
}
Reported by Marcelo Matus.
07/09/2002: beazley
Added parsing support for constructors that try to catch
exceptions in initializers. For example:
class Foo {
Bar b;
public:
Foo(int x) try
: b(x) { ... }
catch(int) {
...
}
}
This has no effect on the generated wrappers. However, the try and catch
parts of the declaration are ignored. See Stroustrup, 3rd Ed, section
14.4.6.1 for details.
07/06/2002: beazley
Fixed bug in template symbol table management. This fixes
two bugs. First, mixing abstract methods, templates, and
inheritance no longer generates a failed assertion.
template <class T>
class A {
public:
virtual void foo() = 0;
};
template <class T>
class B : public A<T>
{
};
%template(A_int) A<int>;
%template(B_int) B<int>;
This fix also fixes a subtle problem with default values and
templates. For example:
template <class C>
struct B {
typedef unsigned int size_type;
static const size_type nindex = static_cast<size_type>(-1);
void foo(size_type index = nindex);
};
Bugs reported by Marcelo Matus.
07/05/2002: ljohnson (Lyle Johnson)
[Ruby] Changed the definition of the SWIG_ConvertPtr() function
for the SWIG/Ruby runtime support so that it looks like the
Python version. If the last argument (flags) is non-zero,
SWIG_ConvertPtr() will raise an exception for type mismatches
as before. If flags is zero, this function will return -1 for
type mismatches without raising an exception.
*** POTENTIAL INCOMPATIBILITY FOR RUBY MODULE ***
07/04/2002: beazley
Overloaded functions/methods/constructors now work in many language
modules. The support is completely transparent--just call the
function normally and SWIG will dispatch to the correct implementation.
There are a variety of issues associated with this. Please refer
to the overloading section of Doc/Manual/SWIGPlus.html for details.
*** NEW FEATURE ***
07/04/2002: beazley
Fixed a bug with namespaces, enums, and templates. For example:
namespace hello {
enum Hello { Hi, Hola };
template <Hello H>
struct traits
{
typedef double value_type;
};
traits<Hi>::value_type say_hi()
{
return traits<Hi>::value_type(1);
}
}
SWIG wasn't generating wrappers that properly qualified
traits<Hi>. Reported by Marcelo Matus.
06/30/2002: beazley
Supplied array variable typemaps for Tcl module. If you have a
variable like this:
int foo[10];
then a set function like this is generated:
void foo_set(int *x) {
memmove(foo,x,10*sizeof(int));
}
06/30/2002: beazley
New %fragment directive. When writing typemaps, it can be easy to
get carried away and write a lot of code. However, doing so causes
tremendous code bloat. A common way to solve this is to write
helper functions. For example:
%{
void some_helper_function() {
...
}
%}
%typemap(in) type {
some_helper_function(...);
}
The only problem with this is that the wrapper file gets polluted
with helper functions even if they aren't used. To fix this,
a new fragment directive is available. For example:
(corrected typo in line below - 06/26/2008)
%fragment("type_header","header") %{
void some_helper_function() {
...
}
%}
%typemap(in, fragment="type_header") type {
some_helper_function(...);
}
In this case, the code fragment is only emitted if the typemap is
actually used. A similar capability is provided for declaration
annotation and the %feature directive. For example:
%feature("fragment","type_header") SomeDeclaration;
The first argument to %fragment is the fragment name. The second argument
is the file section where the fragment should be emitted.
The primary use of this directive is for writers of language modules
and advanced users wanting to streamline typemap code.
*** EXPERIMENTAL NEW FEATURE ***
06/30/2002: beazley
Supplied memberin typemaps for all arrays in an attempt to eliminate
confusion about their use.
06/29/2002: beazley
Experimental support for smart-pointers. When a class defines
operator->() like this
class Foo {
...
Bar *operator->();
...
};
SWIG locates class Bar and tries to wrap its member variables and
methods as part of Foo. For example, if Bar was defined like this:
class Bar {
public:
int x;
int spam();
};
You could do this (in the target language):
f = Foo()
f.x = 4 # Accesses Bar::x
f.spam() # Accesses Bar::spam
The primary use of this feature is to emulate the behavior of C++
smart-pointers---which allow attributes to accessed transparently
through operator->.
This feature is supported automatically in SWIG---no special directives
are needed. To disable this behavior. Use %ignore to ignore
operator->.
*** NEW FEATURE ***
06/26/2002: beazley
Deprecated the %except directive. %exception should be used instead.
06/25/2002: beazley
Major cleanup of the modules directory. Eliminated most
header files, consolidated module code into single files.
06/24/2002: beazley
Reworked the instantiation of language modules. All language
modules must now define a factory function similar to this:
extern "C" Language *
swig_python(void) {
return new PYTHON();
}
This function is then placed in a table and associated with
a command line option in swigmain.cxx.
This approach has a number of benefits. It decouples the
SWIG main program from having to know about the class
definitions for each module. Also, by using a factory
function, it will be easier to implement dynamic loading
of modules (simply load the file and invoke the factory
function).
06/24/2002: beazley
Fixed syntax error for reference conversions. For example:
operator Foo &();
06/24/2002: beazley
Fixed syntax error for operator new[] and operator delete[].
06/24/2002: beazley
Fixed code generation problem for constants and default arguments
involving templates.
06/19/2002: ljohnson (Lyle Johnson)
[Ruby] Fixed a bug for the '-feature' command line argument;
that setting was effectively being ignored and so the feature
name was always set equal to the module name.
06/17/2002: beazley
Fixed problems with static members and enums in templates.
Version 1.3.13 (June 17, 2002)
==============================
06/16/2002: beazley
Fixed a bug with __FILE__ expansion in the preprocessor. On Windows,
the backslash (\) is now converted to (\\) in the string literal
used for __FILE__. Reported by Steve Glaser.
06/14/2002: beazley
Fixed warning message about 'name private in this context'. The
warning is only generated for public methods. Reported by
Scott Michel.
06/14/2002: beazley
Fixed some problems related to template instantiation
and namespaces. When SWIG expands a template, it does
so with fully resolved types. For example, if you have this:
template<class T> class foo { };
typedef double Double;
%template(foo_d) foo<Double>;
then, it is handled as foo<double> in the typesystem.
This fixes a number of subtle problems with inheritance
and templates.
06/14/2002: ljohnson (Lyle Johnson)
[Ruby] Added missing bool typemaps for INPUT, OUTPUT and
INOUT in Lib/ruby/typemaps.i.
05/29/2002: cheetah (William Fulton)
[Java] Fix for a couple of broken pragmas.
05/29/2002: cheetah (William Fulton)
Fix for unnecessary cast when wrapping global variable where
the type is not parsed by SWIG - Java variables example
failure as reported by Larry Virden.
06/10/2002: beazley
Modified %template to allow for empty instantiations.
%template() foo<int,int>;
This registers foo<int,int> with the type system, but
doesn't wrap it (same as %ignore). This may only be a
temporary measure. SWIG might be able to automatically
instantiate templates in certain cases.
06/10/2002: beazley
Fixed function prototype problems with Tcl 8.4
06/09/2002: beazley
Fixed problem with templates and location of base classes.
This one is a little mind-bending, but here is an example
that illustrates:
template <class ArgType, class ResType>
struct traits
{
typedef ArgType arg_type;
typedef ResType res_type;
};
template <class ArgType, class ResType>
struct Function
{
};
template <class AF, class AG>
struct Class : Function<typename traits<AF, AG>::arg_type,
typename traits<AF, AG>::res_type>
{
};
%template(traits_dd) traits <double, double>;
%template(Function_dd) Function <double, double>;
%template(Class_dd) Class <double, double>;
In this example, the base class of 'Class' is determined from
the Function template, but the types are obtained through typedefs.
Because of this, SWIG could not locate the wrapped base class
(Function<double,double>). Should be fixed in 1.3.13 even
though I can think of a million other things that might
also be broken.
06/07/2002: beazley
Fixed a problem with conversion operators. If you had an
operator like this,
operator double() const;
SWIG was ommitting the "const" qualifier. This affected
%rename and other directives. Reported by Zhong Ren.

Lessened the strictness of abstract class checking. If
you have code like this:
class Foo {
public:
virtual int method() = 0;
};
class Bar : public Foo {
public:
Bar();
~Bar();
};
SWIG will go ahead and generate constructor/destructors
for Bar. However, it will also generate a warning message
that "Bar" might be abstract (since method() isn't defined).
In SWIG-1.3.12, SWIG refused to generate a constructor at all.
06/07/2002: beazley
Change to %template directive. If you specify something like this:
%template(vi) std::vector<int>;
It is *exactly* the same as this:
namespace std {
%template(vi) vector<int>;
}
SWIG-1.3.12 tried to instantiate the template outside of the namespace
using some trick. However, this was extremely problematic and full
holes. This version is safer.
06/07/2002: beazley
Fixed bug with scope qualification and templates. For example:
A<B::C>::DD
Before, this was separated as scopes A<B, C>, and DD. Fixed now.
06/06/2002: beazley
Allow the following syntax:
class A { };
struct B : A { ... };
A base class without a specifier is assumed to be public for a struct.
06/06/2002: beazley
Fixed syntax error with template constructor initializers.
Reported by Marcelo Matus.
06/06/2002: beazley
Fixed bug with default template arguments.
Reported by Marcelo Matus.
06/05/2002: beazley
Fixed subtle problems with %rename directive and template
expansion.
Code like this should now work:
%rename(blah) foo<double>::method;
...
template<class T> class foo {
public:
void method();
};
%template(whatever) foo<double>;
06/05/2002: beazley
Resolved some tricky issues of multi-pass compilation and
and inheritance. The following situation now generates
an error:
class Foo : public Bar {
...
};
class Bar {
...
};
The following code generates a warning about incomplete classes.
class Bar;
class Foo : public Bar { };
The following code generates a warning about an undefined class.
class Foo : public Bar { }; // Bar undefined
This fixes a failed assertion bug reported by Jason Stewart.

[Ruby] Added a warning message for the Ruby module about the lack
of support for multiple inheritance. Only the first base class
listed is used and the others are ignored. (Reported by Craig
Files).
06/03/2002: beazley
Fixed a bug with struct declarations and typedef. For example:
typedef struct Foo Foo;
struct Foo {
...
};
A few other subtle struct related typing problems were
also resolved.
Version 1.3.12 (June 2, 2002)
=============================
05/30/2002: beazley
Fixed problem related to forward template class declarations and
namespaces. Bug reported by Marcelo Matus.
05/30/2002: beazley
Added 'make uninstall' target. Contributed by Joel Reed.
05/29/2002: beazley
Fixed rather insidious bug with %rename, %feature and template specialization.
For example:
%exception vector::__getitem__ {
... some exception ...
}
template<class T> class vector {
...
T __getitem__(int index); // Fine
...
};
template<> class vector<int> {
...
T __getitem__(int index); // Oops.
...
};
Now, the %exception directive (and other features) should correctly apply to
both vector and specializations.
05/29/2002: beazley
Subtle changes to %template() directive. Template arguments are now
reduced to primitive types in template matching. For example:
template<class T> class vector<T *> {
... partial specialization ...
}
typedef int *IntPtr; // Gross typedef
// Gets the above partial specialization
%template(vectorIntPtr) vector<IntPtr>;
This change is extremely subtle, but it fixes a number of potential
holes in Luigi's STL library modules. For example:
typedef int Integer;
%template(vectori) vector<int>;
05/29/2002: beazley
Fixed rather insidious typemap bug related to const. const
was being discarded through typedefs.
05/29/2002: ljohnson (Lyle Johnson)
[Ruby] Added input typemaps for const references to primitive
types (in Lib/ruby/ruby.swg).
05/29/2002: cheetah (William Fulton)
[Java] The java arrray support functions are enclosed by
a SWIG_NOARRAYS #define. Useful if not using arrays and
it is desirable to minimise the amount of compiled code.
05/29/2002: cheetah (William Fulton)
[Java] Enums were not renamed when using %name or %rename
fix.
05/28/2002: ljohnson
[Ruby] Modified the name of the wrapper functions for the
"new" singleton method and "initialize" instance method for
consistency with the other language modules. The wrapper name
for the function that implements "new" is alloc_classname and
the wrapper name for the function that implements "initialize"
is new_classname.
05/27/2002: beazley
Changes to runtime. Pointer conversion/creation functions
now almost always have an extra "flags" argument. For
example:
SWIG_ConvertPtr(obj, void **, swig_type_info *ty, int flags);
^^^^^^^^^^
This extra parameter is reserved for future expansion and will
be used for more control over pointers in future versions.
05/27/2002: beazley
Fix for C++ classes with private assignment operators. It
is now possible to safely return objects like this by value.
Caveat: the class must provide a copy constructor.
05/26/2002: beazley
-proxy option added to many language modules. This is the
same as -shadow. We are merely changing terminology.
05/26/2002: beazley
[perl] Fixed some inconsistencies in the -package option.
-package merely sets the package name to be used on the
wrappers. It does not change the name of the shared library
file or the name of the generated .pm file. This was
broken at some point, but works again now.
05/25/2002: beazley
[perl] Fixed [ 475452 ] memory leak in return-by-value.
Problem related to static member variables returning newly
allocated objects. Reported by Roy Lecates.
05/25/2002: beazley
[perl] Fixed [ 513134 ] %BLESSEDMEMBERS isn't always right.
Reported by Fleur Diana Dragan.
05/25/2002: beazley
Fixed [ 540735 ] -importall and the -I option.
05/25/2002: beazley
[guile] Fixed [ 532723 ] Default arg for char* can SegV.
Error in guile module. Reported by Brett Williams.
05/25/2002: beazley
Subtle change to typemap application code. The "freearg"
typemap must exactly match up with the "in" or "ignore"
typemap. For example:
%typemap(in) (char *data, int len) { ... }
%typemap(freearg) char *data { ... }
void foo(char *data, int len);
In this case, the "in" typemap is applied, but the
freearg typemap is not. This is because the freearg
typemap doesn't match up with the input argument sequence.
05/25/2002: beazley
Fixed [ 548272 ] Default argument code missing braces.
Reported by Brett Williams.
05/25/2002: beazley
Fixed [ 547730 ] SwigValueWrapper needed for constructors.
Reported by William Fulton.
05/25/2002: beazley
Undefined identifiers now evaluate to 0 when evaluating
preprocessor expressions. For example:
#if !FOO
...
#endif
where FOO is undefined or set to some non-numeric value.
Fixes [ 540868 ] #if defined whatever - not parsed.
Reported by Adam Hupp.
05/24/2002: beazley
SWIG now ignores the C++ 'export' keyword.
05/23/2002: beazley
Some refinement of type-name mangling to account for pointers, arrays,
references, and other embedded type constructs.
