SWIG (Simplified Wrapper and Interface Generator)
See CHANGES.current for current version.
Version 1.3.39 (21 March 2009)
==============================
2009-03-19: bhy
[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.
*** POTENTIAL INCOMPATIBILITY ***
2009-03-12: wsfulton
[Ruby] Fix #2676738 SWIG generated symbol name clashes.
2009-03-01: bhy
[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.
2009-03-01: bhy
[Python] Fix SF#2583160. Now the importer in Python shadow wrapper take care of the
case that module already imported at other place.
2009-02-28: bhy
[Python] Fix SF#2637352. Move struct declaration of SWIG_module in pyinit.swg before
the method calls, since some C compiler don't allow declaration in middle of function
body.
2009-02-21: wsfulton
[Allegrocl] Fix seg fault wrapping some constant variable (%constant) types.
2009-02-20: wsfulton
[CFFI] Fix seg faults when for %extend and using statements.
2009-02-20: wsfulton
Fix SF #2605955: -co option which broke in 1.3.37.
2009-02-20: wsfulton
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
properly after running 'make partialcheck-test-suite'.
2009-02-14: wsfulton
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
ignored for member variables within a %extend block.
2009-02-12: wsfulton
Remove unnecessary temporary variable when wrapping return values that are references.
Example of generated code for wrapping:
struct XYZ {
std::string& refReturn();
};
used to be:
std::string *result = 0 ;
...
{
std::string &_result_ref = (arg1)->refReturn();
result = (std::string *) &_result_ref;
}
Now it is:
std::string *result = 0 ;
...
result = (std::string *) &(arg1)->refReturn();
2009-02-08: bhy
Change the SIZE mapped by %pybuffer_mutable_binary and %pybuffer_binary in pybuffer.i from
the length of the buffer to the number of items in the buffer.
2009-02-08: wsfulton
Fix %feature not working for conversion operators, reported by Matt Sprague, for example:
%feature("cs:methodmodifiers") operator bool "protected";
2009-02-07: wsfulton
[MzScheme] Apply #2081967 configure changes for examples to build with recent PLT versions.
Also fixes Makefile errors building SWIG executable when mzscheme package is installed
(version 3.72 approx and later).
2009-02-04: talby
[Perl] Fix SF#2564192 reported by David Kolovratnk.
SWIG_AsCharPtrAndSize() now handles "get" magic.
Version 1.3.38 (31 January 2009)
================================
2009-01-31: bhy
[Python] Fix SF#2552488 reported by Gaetan Lehmann. Now %pythonprepend
and %pythonappend have correct indentation.
2009-01-31: bhy
[Python] Fix SF#2552048 reported by Gaetan Lehmann. The parameter list
of static member function in generated proxy code should not have the
'self' parameter.
2009-01-29: wsfulton
Fix regression introduced in 1.3.37 where the default output directory
for target language specific files (in the absence of -outdir) was no
longer the same directory as the generated c/c++ file.
2009-01-28: wsfulton
[Java, C#] Fix proxy class not being used when the global scope operator
was used for parameters passed by value. Reported by David Piepgrass.
2009-01-15: wsfulton
[Perl] Fix seg fault when running with -v option, reported by John Ky.
Version 1.3.37 (13 January 2009)
================================
2009-01-13: mgossage
[Lua] Added contract support for requiring that unsigned numbers are >=0
Rewrote much of Examples/Lua/embed3.
Added a lot to the Lua documentation.
2009-01-13: wsfulton
Fix compilation error when using directors on protected virtual overloaded
methods reported by Sam Hendley.
2009-01-12: drjoe
[R] Fixed handling of integer arrays
2009-01-10: drjoe
[R] Fix integer handling in r to deal correctly with signed
and unsigned issues
2009-01-10: wsfulton
Patch #1992756 from Colin McDonald - %contract not working for classes
in namespace
2009-01-05: olly
Mark SWIGPERL5, SWIGPHP5, and SWIGTCL8 as deprecated in the source
code and remove documentation of them.
2008-12-30: wsfulton
Bug #2430756. All the languages now define a macro in the generated C/C++
wrapper file indicating which language is being wrapped. The macro name is the
same as those defined when SWIG is run, eg SWIGJAVA, SWIGOCTAVE, SWIGCSHARP etc
and are listed in the "Conditional Compilation" section in the documentation.
2008-12-23: wsfulton
[Java] Fix #2153773 - %nojavaexception was clearing the exception feature
instead of disabling it. Clearing checked Java exceptions also didn't work.
The new %clearjavaexception can be used for clearing the exception feature.
2008-12-22: wsfulton
Fix #2432801 - Make SwigValueWrapper exception safe for when copy constructors
throw exceptions.
2008-12-21: wsfulton
Apply patch #2440046 which fixes possible seg faults for member and global
variable char arrays when the strings are larger than the string array size.
2008-12-20: wsfulton
The ccache compiler cache has been adapted to work with SWIG and
named ccache-swig. It now works with C/C++ compilers as well as SWIG
and can result in impressive speedups when used to recompile unchanged
code with either a C/C++ compiler or SWIG. Documentation is in CCache.html
or the installed ccache-swig man page.
2008-12-12: wsfulton
Apply patch from Kalyanov Dmitry which fixes parsing of nested structs
containing comments.
2008-12-12: wsfulton
Fix error message in some nested struct and %inline parsing error situations
such as unterminated strings and comments.
2008-12-07: olly
[PHP] Fix warnings when compiling generated wrapper with GCC 4.3.
2008-12-06: wsfulton
[PHP] Deprecate %pragma(php4). Please use %pragma(php) instead.
The following two warnings have been renamed:
WARN_PHP4_MULTIPLE_INHERITANCE -> WARN_PHP_MULTIPLE_INHERITANCE
WARN_PHP4_UNKNOWN_PRAGMA -> WARN_PHP_UNKNOWN_PRAGMA
*** POTENTIAL INCOMPATIBILITY ***
2008-12-04: bhy
[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
*** POTENTIAL INCOMPATIBILITY ***
2008-12-02: wsfulton
[Python] Apply patch #2143727 from Serge Monkewitz to fix importing base classes
when the package option is specified in %module and that module is %import'ed.
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.
2008-11-23: wsfulton
[ruby] Apply patch #2263850 to fix ruby/file.i ... rubyio.h filename change in
ruby 1.9.
2008-11-23: wsfulton
Apply patch #2319790 from Johan Hake to fix shared_ptr usage in std::tr1 namespace.
2008-11-21: wsfulton
The use of the include path to find the input file is now deprecated.
This makes the behaviour of SWIG the same as C/C++ compilers in preparation
for use with ccache.
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.
2008-11-11: wsfulton
[Java] Add patch #2152691 from MATSUURA Takanori which fixes compiles using the
Intel compiler
2008-11-01: wsfulton
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") "";
struct wxAnotherWidget {
void wxDoSomething();
};
2008-09-26: mutandiz
[allegrocl]
Lots of test-suite work.
- Fix ordering of wrapper output and %{ %} header output.
- Fix declarations of local vars in C wrappers.
- Fix declaration of defined constants in C wrappers.
- Fix declaration of EnumValues in C wrappers.
- add some const typemaps to allegrocl.swg
- add rename for operator bool() overloads.
2008-09-25: olly
[PHP5] Fill in typemaps for SWIGTYPE and void * (SF#2095186).
2008-09-22: mutandiz (Mikel Bancroft)
[allegrocl]
- Support wrapping of types whose definitions are not seen by
SWIG. They are treated as forward-referenced classes and if a
definition is not seen are treated as (* :void).
- Don't wrap the contents of unnamed namespaces.
- More code cleanup. Removed some extraneous warnings.
- start work on having the allegrocl mod pass the cpp test-suite.
2008-09-19: olly
[PHP5] Add typemaps for long long and unsigned long long.
2008-09-18: wsfulton
[C#] Added C# array typemaps provided by Antti Karanta.
The arrays provide a way to use MarshalAs(UnmanagedType.LPArray)
and pinning the array using 'fixed'. See arrays_csharp.i library file
for details.
2008-09-18: wsfulton
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
module attribute to be added to %import, eg
%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);
}
2008-09-18: olly
[PHP5] Fix extra code added to proxy class constructors in the case
where the only constructor takes no arguments.
2008-09-18: olly
[PHP5] Fix wrapping of a renamed enumerated value of an enum class
member (SF#2095273).
2008-09-17: mutandiz (Mikel Bancroft)
[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.
2008-09-12: bhy
[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 %{ ... %}
2008-09-02: richardb
[Python] Commit patch #2089149: Director exception handling mangles
returned exception. Exceptions raised by Python code in directors
are now passed through to the caller without change. Also, remove
the ": " prefix which used to be added to other director exceptions
(eg, those due to incorrect return types).
2008-09-02: wsfulton
[Python] Commit patch #1988296 GCItem multiple module linking issue when using
directors.
2008-09-02: wsfulton
[C#] Support for 'using' and 'fixed' blocks in the 'csin' typemap is now
possible through the use of the pre attribute and the new terminator attribute, eg
%typemap(csin,
pre=" using (CDate temp$csinput = new CDate($csinput)) {",
terminator=" } // terminate temp$csinput using block",
) const CDate &
"$csclassname.getCPtr(temp$csinput)"
See CSharp.html for more info.
2008-09-01: wsfulton
[CFFI] Commit patch #2079381 submitted by Boris Smilga - constant exprs put into
no-eval context in DEFCENUM
2008-08-02: wuzzeb
[Chicken,Allegro] Commit Patch 2019314
Fixes a build error in chicken, and several build errors and other errors
in Allegro CL
2008-07-19: wsfulton

2008-07-17: wsfulton
Fix SF #2019156 Configuring with --without-octave or --without-alllang
did not disable octave.
2008-07-14: wsfulton
[Java, C#] Fix director typemaps for pointers so that NULL pointers are correctly
marshalled to C#/Java null in director methods.
2008-07-04: olly
[PHP] For std_vector.i and std_map.i, rename empty() to is_empty()
since "empty" is a PHP reserved word. Based on patch from Mark Klein
in SF#1943417.
2008-07-04: olly
[PHP] The deprecated command line option "-make" has been removed.
Searches on Google codesearch suggest that nobody is using it now
anyway.
2008-07-04: olly
[PHP] The SWIG cdata.i library module is now supported.
2008-07-03: olly
[PHP] The deprecated command line option "-phpfull" has been
removed. We recommend building your extension as a dynamically
loadable module.
2008-07-02: olly
[PHP4] Support for PHP4 has been removed. The PHP developers are
no longer making new PHP4 releases, and won't even be providing
patches for critical security issues after 2008-08-08.
2008-07-02: olly
[Python] Import the C extension differently for Python 2.6 and
later so that an implicit relative import doesn't produce a
deprecation warning for 2.6 and a failure for 2.7 and later.
Patch from Richard Boulton in SF#2008229, plus follow-up patches
from Richard and Haoyu Bai.
Version 1.3.36 (24 June 2008)
=============================
06/24/2008: wsfulton
Remove deprecated -c commandline option (runtime library generation).
06/24/2008: olly
[PHP] Fix assertion failure when handling %typemap(in,numinputs=0)
(testcase ignore_parameter).
06/24/2008: olly
[PHP] Fix segfault when wrapping a non-class function marked with
%newobject (testcase char_strings).
06/22/2008: wsfulton
[Java] Add a way to use AttachCurrentThreadAsDaemon instead of AttachCurrentThread
in director code. Define the SWIG_JAVA_ATTACH_CURRENT_THREAD_AS_DAEMON macro, see
Lib/java/director.swg.
06/21/2008: wsfulton
[Ruby] Fix crashing in the STL wrappers (reject! and delete_if methods)
06/19/2008: wsfulton
[Java, C#] C# and Java keywords will be renamed instead of just issuing a warning
and then generating uncompileable code. Warning 314 gives the new name when a
keyword is found.
06/19/2008: wsfulton
[R] Keyword handling added. R Keywords will be renamed as necessary.
Warning 314 gives the new name when a keyword is found.
06/17/2008: mgossage
[Lua] Added missing support for bool& and bool*. Added runtest for li_typemaps testcase.
(Bug #1938142)
06/07/2008: bhy
Added test case keyword_rename, then made the keyword renaming works properly
by fixing Swig_name_make() for a incomplete condition checking.
06/02/2008: wsfulton
[Java, C#] Fix enum wrappers when using -noproxy.
05/30/2008: bhy
Added std::wstring into Lib/typemaps/primtypes.swg, since it is also a primitive
type in SWIG - fixed SF #1976978.
05/29/2008: wsfulton
[Java, C#] Fix variable wrappers when using -noproxy.
05/29/2008: bhy
[Python] Fixed a typo of %#ifdef in Lib/python/pycontainer.swg, which is related
to -extranative SWIG option - SF #1971977.
05/20/2008: wsfulton
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"
05/19/2008: drjoe
[R] Fixed define that was breaking pre-2.7. Checked in
patch from Soren Sonnenburg that creates strings in
version independent way
05/15/2008: wsfulton
[Java] Fix variable name clash in directors - SF #1963316 reported by Tristan.
05/14/2008: wsfulton
Add an optimisation for functions that return objects by value, reducing
the number of copies of the object that are made. Implemented using an
optional attribute in the "out" typemap called "optimal". Details in
Typemaps.html.
05/11/2008: olly
[PHP] Check for %feature("notabstract") when generating PHP5 class
wrapper.
05/11/2008: wsfulton
Fix SF #1943608 - $self substitution in %contract, patch submitted by
Toon Verstraelen.
05/09/2008: olly
[PHP] Fix char * typemaps to work when applied to signed char * and
unsigned char * (uncovered by testcase apply_strings).
05/09/2008: wsfulton
Fix wrapping of char * member variables when using allprotected mode.
Bug reported by Warren Wang.
05/09/2008: olly
[PHP] Fix bad PHP code generated when wrapping an enum in a
namespace (uncovered by testcase arrays_scope).
05/09/2008: olly
[PHP] SWIG now runs the PHP testsuite using PHP5, not PHP4. PHP4
is essentially obsolete now, so we care much more about solid PHP5
support.
05/07/2008: wsfulton
STL fixes when using %import rather than %include and the Solaris Workshop
compiler and the Roguewave STL.
05/07/2008: wsfulton
Fix wrapping of overloaded protected methods when using allprotected mode.
Bug reported by Warren Wang.
05/03/2008: wsfulton
Commit patch #1956607 to add -MT support from Richard Boulton.
This patch mirrors the gcc -MT option which allows one to change the default
Makefile target being generated when generating makefiles with the -M family
of options. For example:
$ swig -java -MM -MT overiddenname -c++ example.i
overiddenname: \
example.i \
example.h
04/30/2008: mgossage
[Lua] Removed generation of _wrap_delete_XXXXX (wrappered destructor)
which was unused and causing warning with g++ -Wall.
Removed other unused warning in typemaps.i and other places.
Added Examples/lua/embed3, and run tests a few test cases.
04/24/2008: olly
[Python] Fix generated code for IBM's C++ compiler on AIX (patch
from Goeran Uddeborg in SF#1928048).
04/24/2008: olly
Rename BSIZE in Examples/test-suite/arrays_scope.i to BBSIZE to
avoid a clash with BSIZE defined by headers on AIX with Perl
(reported in SF#1928048).
04/20/2008: wsfulton
Add the ability to wrap all protected members when using directors.
Previously only the virtual methods were available to the target language.
Now all protected members, (static and non-static variables, non-virtual methods
and static methods) are wrapped when using the allprotected mode. The allprotected
mode is turned on in the module declaration:
%module(directors="1", allprotected="1") modulename
Version 1.3.35 (7 April 2008)
=============================
04/07/2008: wsfulton
[Lua] Add missing pointer reference typemaps
04/06/2008: wsfulton
Fix stack overflow when using typemap warning suppression, eg
%warnfilter(SWIGWARN_TYPEMAP_CHARLEAK_MSG)
04/05/2008: wsfulton
[Python] Fix shared_ptr typemaps so that %pythonnondynamic can be used. Also corrects
display of the proxy class type. Reported by Robert Lupton.
04/04/2008: olly
[Python] Add %newobject reference to python memory management subsection of manual
(patch from mdbeachy in SF#1894610).
03/27/2008: wsfulton
[Python] Fix shared_ptr typemaps where the pointer type is a templated type with
with more than one parameter. Reported by Robert Lupton.
03/27/2008: mgossage
[Lua] Added a typemap DISOWN for SWIGTYPE* and SWIGTYPE[], and support for %delobject feature.
Added Examples/lua/owner which demonstrates the use of the memory management.
03/26/2008: wsfulton
[Java] Apply patch #1844301 from Monty Taylor to suppress enum constructor
unused warnings.
03/26/2008: wsfulton

[R] Now setting S4 flag in SWIG created objects. This
fixes R-SWIG for 2.6 and warning for 2.6 failure has been removed.
02/11/2008: mgossage
[Lua] Added a patch by Torsten Landschoff to fix the unary minus issue
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.
01/30/2008: mgossage
Small update to documentation in Typemaps.html, to warn about use of local
variables in typemaps for multiple types.

More updates to the configure script for detecting lua.
Also looks in /usr/include/lua*
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

Fix using statements using a base class method where the methods were overloaded.
Depending on the order of the using statements and method declarations, these

[R] Add support for Windows (Visual C++ 8 tested)
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
extension are easy enough to write for the user's preferred build
tool). Also recommend against the use of "-phpfull" (it's only
really useful when static linking, and a dynamically loadable
module is virtually always the better approach).
11/09/2007: olly
Fix --help output to note that `export SWIG_FEATURES' is required.

The code as it was happened to work on x86, but broke on x86_64 (and
probably any other platforms which require -fPIC).

value of errno if there isn't an error in the call.
10/16/2007: wsfulton
Deprecate %attribute_ref and replace with %attributeref. There is just an argument
order change in order to maintain consistency with %attribute, from:

10/12/2007: wsfulton
[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.
10/12/2007: wsfulton
[Java] Ensure the premature garbage collection prevention parameter (pgcpp) is generated

[C#] The $csinput special variable can be used in the csvarin typemap where it is always
expanded to 'value'.
09/19/2007: wsfulton
[C#] Fix bug reported by Glenn A Watson and #1795260 where the cstype typemap used the 'ref'

The type for the property now correctly comes from the 'out' attribute in the cstype typemap.
09/19/2007: wsfulton
[Java] Fix const std::wstring& typemaps
09/19/2007: wsfulton
[Java] Ensure the premature garbage collection prevention parameter (pgcpp) is generated
where a parameter is passed by pointer reference, eg in the std::vector wrappers. The pgcpp
is also generated now when user's custom typemaps use a proxy class in the jstype typemap
and a 'long' in the jtype typemap.

Fix %ignore on constructors which are not explicitly declared [SF #1777712]
09/05/2007: wuzzeb (John Lenz)
- 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.
08/31/2007: wsfulton
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
various stages, where <n> is a comma separated list of stages 1-4.For example, to

swig -debug-top 1,3
- Deprecate the following options which have equivalents below:
-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

05/25/2007: wsfulton
Fixed %rename inconsistency in conversion operators as reported by Zhong Ren. The matching
is now done on the operator name in the same way as it is done for parameters. For example:
%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

document the features supported by Ruby in documenting its modules.
Made rdoc documentation spit out the full name of the class +
method name. Albeit this will make the current rdoc not recognize
the method, this is still needed to disambiguate between different
classes with similar methods (rdoc was created to document the
ruby source which only contains one class per c file, unlike swig)
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,
std::multiset, std::deque and std::string are now properly
supported, including their iterators, support for containing
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.
05/02/2007: gga

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.

%include <typemaps.i>
%feature("numoutputs","0") { Class::member_function1 };
%typemap(out) MStatus { // some code, like check mstatus

New command line option -macroerrors. When supplied, this will force

can expand the error back to its source---something which may simplify
debugging.

[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.

[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.

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

string in PHP using: (string)x

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

[php] Rename ErrorCode and ErrorMsg #define-s to SWIG_ErrorCode

wrapping (patch from Darren Warner in SF bug #1466086). Any
user typemaps which use ErrorCode and/or ErrorMsg directly will
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
code.
validIdentifier now more closely approximates what may be
a legal common lisp symbol.

03/02/2006: wsfulton
[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 acheive 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.

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.

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 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();
};

[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 clashings 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")
