Version 4.0.1 (21 Aug 2019)
===========================
2019-08-20: TekuConcept
[Javascript] #1535 Add %native support to Javascript.
2019-08-20: bkotzz
[Java] #1616 Add SWIG_JavaIllegalStateException to support throwing
java.lang.IllegalStateException from JNI code.
2019-08-19: sjml
[Lua] #1596 tostring output changes to show the underlying C/C++ pointer.
2019-08-08: rokups
[C#, Java] #1601 Fix invalid code generated for "%constant enum EnumType.
2019-08-07: wsfulton
[Python] Fix method overloading of methods that take STL containers of different
types. The following usage (using std::vector) would fail when using -builtin:
%include <std_string.i>
%include <std_vector.i>
%inline %{
struct X {};
%}
%template(VectorX) std::vector<X>;
%template(VectorInt) std::vector<int>;
%inline %{
using namespace std;
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 typehecking.
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):
File "runme3.py", line 23, in <module>
check(VectorOverload(v), "vector<X>")
SystemError: <built-in function VectorOverload> returned a result with an error set
2019-08-01: wsfulton
#1602 Fix regression in 4.0.0 where a template function containing a parameter
with the same name as the function name led to the parameter name used in the
target language being incorrectly modified.
2019-07-29: wsfulton
Remove all generated files on error. Previously generated files were not removed,
potentially breaking Makefiles using file dependencies, especially when -Werror
(warnings as errors) was used.

\code.
2019-07-09: IsaacPascual
[C#, Java] #1570 Fix name of generated C#/Java classes for %interface macros
in swiginterface.i when wrapping nested C++ classes.
2019-07-05: wsfulton
[Python] #1547 Whitespace fixes in Doxygen translated comments into pydoc comments
for Sphinx compatibility.
2019-06-28: wsfulton
[MzScheme, OCaml] #1559 $arg and $input were incorrectly substituted in the
argout typemap when two or more arguments were present.
2019-06-24: wsfulton
[Python, Ruby] #1538 Remove the UnknownExceptionHandler class in order to be
C++17 compliant as it uses std::unexpected_handler which was removed in C++17.
This class was intended for director exception handling but was never used by
SWIG and was never documented.

2019-06-06: bkotzz
[Java] #1552 Improve performance in Java std::vector constructor wrapper that takes
a native Java array as input.
2019-06-03: olly
[Python] Fix regression in implicit_conv handling of tuples,

PSR-2 says it MUST be omitted for files containing only PHP.
Version 4.0.0 (27 Apr 2019)
===========================
2019-04-24: vadz
#1517 Fix crash if "@return" Doxygen tag was used on a node without any return type.
2019-04-24: vadz
#1515 Fix parsing of enums with trailing comma when using -doxygen.
2019-04-19: ianlancetaylor
[Go] #1055 When generating Go code, make -cgo the default. Add new -no-cgo option
to disable the default.
2019-04-19: pbecherer
[Tcl] #1508 Fix Visual Studio 2015 and later compilation errors due to snprintf macro
definition.
2019-04-09: wsfulton
[C#] Fix FxCop warning CA2002 in SWIGPendingException - a lock on a reference of
type 'Type'.
2019-03-30: wsfulton
[Java, D] Add the parameters typemap attribute to the javadestruct,
javadestruct_derived, ddispose, ddispose_derived typemaps to mirror enhanced
flexibility in the csdisposing and csdisposing_derived (C#) typemaps. If provided
the contents are generated as the delete/dispose method's parameters declaration.
2019-03-30: wsfulton
[C#] #421 Fix FxCop warning CA1063 by implementing the recommended Dispose methods for
the IDisposable interface. Previously just the Dispose() method was generated.
Now the Dispose() and Dispose(bool disposing) methods are generated.
Changes are required if custom "csfinalize", "csdestruct" or "csdestruct_derived"
typemaps are being used. Details in #421 on Github. SWIG will error out if one of
the "csfinalize, "csdestruct" or "csdestruct_derived" typemaps are found. Example
error message:
foo.h:60: Error: A deprecated csfinalize typemap was found for Foo, please remove
it and replace all csdestruct, csdestruct_derived and csfinalize typemaps by the
csdispose, csdispose_derived, csdisposing and csdisposing_derived typemaps.

2019-03-25: Liryna
[C#] #1143 Add std_list.i for std::list support.
The C# std::list<T> wrappers are made to look and feel like a C#
System.Collections.Generic.LinkedList<> collection.
The IEnumerable<> interface is implemented in the proxy class.
The ICollection<> interface can also be implemented to provide enhanced functionality
whenever a C++ operator== is available. This is the case for when T is a
primitive type or a pointer. If T does define an operator==, then use the
SWIG_STD_LIST_ENHANCED macro to obtain this enhanced functionality, for example:
SWIG_STD_LIST_ENHANCED(SomeNamespace::Klass)
%template(ListKlass) std::list<SomeNamespace::Klass>;
2019-03-18: richardbeare
[R] #1328 Non-trivial enums are working now. The enum values are now obtained from
the C/C++ layer. const reference enums and C++11 enum classes are also now working.
2019-03-14: mochizk
[Javascript] #1500 Fix compilation errors due to deprecating V8 API in Node.js.
New V8 API is used if node.js >= v10.12, or if V8 >= v7.0.
2019-03-12: vadz
[C#] #1495 Add std_set.i for std::set support.
2019-03-11: dirteat,opoplawski
[Octave] Fix compilation errors in Octave 5.1.
error: format not a string literal and no format arguments [-Werror=format-security]
2019-02-28: wsfulton
[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);
*** POTENTIAL INCOMPATIBILITY ***
2019-02-25: wsfulton
[Python] Fix compile errors wrapping overloaded functions/constructors where a vararg
function is declared after a non-vararg function.
2019-02-23: zphensley42
Use fully qualified name 'java.lang.Object' instead of 'Object' in generated code to
avoid clashes with wrapped C++ classes called 'Object'.
2019-02-23: gtbX
[Java] #1035 Add (const char *STRING, size_t LENGTH) typemaps in addition to the non-const
typemaps (char *STRING, size_t LENGTH) which does not attempt to write back to the const
string.
2019-02-22: tamuratak
[Ruby] #984 Add support for RTypedData introduced in Ruby 1.9.3.
2019-02-22: ZackerySpytz
#1483 Fix compilation failures when a director class has final methods.
2019-02-21: wsfulton
[Java] #1240 Suppress Java 9 deprecation warnings on finalize method.
2019-02-21: ZackerySpytz
#1480 Fix some rejections of valid floating-point literals.
2019-02-19: wsfulton
#1475 Fix regression parsing gcc preprocessor linemarkers in the form:
# linenum filename flags
2019-02-18: jakecobb
[Python] #945 #1234 Elements in std::vector memory access fix.
Accessing an element in a std::vector obtains a reference to the element via an
iterator pointing to the element in the container. If the vector is garbage collected,
the SWIG wrapper containing the pointer to the element becomes invalid. The fix is
to obtain a back-reference to the container by the wrapper to the element in the Python
layer to prevent the garbage collector from destroying the underlying container.
2019-02-17: wsfulton
Fix typemap matching to expand template parameters when the name contains
template parameters. In the %typemap below the type is T and the name is X<T>::make
and the name now expands correctly to X< int >::make
template<typename T> struct X {
%typemap(out) T X<T>::make "..."
T make();
};
%template(Xint) X<int>;
2019-02-16: wsfulton
Fix parser error containing multiple #define statements inside an enum.
The second #define fails to parse:
enum FooEnum {
ENUM1 = 0,
ENUM2 = 1,
#define MACRO_DEF1 "Hello"
#define MACRO_DEF2 "World!"
ENUM3 = 2,
ENUM4 = 3,
};
Bug mentioned at https://sourceforge.net/p/swig/patches/333/
2019-02-14: wsfulton
Add some missing copy constructors into STL containers.
2019-02-14: bkotzz
[Java] #1356 Add STL containers:
std::unordered_map
std::unordered_set
std::set
2019-02-14: bkotzz
[Java] #1356 std::map wrappers have been modified. Now the Java proxy class
extends java.util.AbstractMap. The std::map container looks and feels much like
a java.util.HashMap from Java.
A few members have changed their names. If the old method signatures are needed,
then copy std_map.i from swig-3.0.12 and use that instead. Alternatively,
add the old missing methods to the new methods by using the following %proxycode:
%extend std::map {
%proxycode %{
// Old API
public boolean empty() {
return isEmpty();
}
public void set($typemap(jboxtype, K) key, $typemap(jboxtype, T) x) {
put(key, x);
}
public void del($typemap(jboxtype, K) key) {
remove(key);
}
public boolean has_key($typemap(jboxtype, K) key) {
return containsKey(key);
}
%}
}

[PHP] A renamed constructor is now wrapped as a static method in
PHP.
2019-02-08: olly
[PHP] Don't generate code which references $r when $r hasn't been

void and took at least one const std::string& parameter.
2019-02-08: olly
[PHP] The generated code is now compatible with PHP 7.3, and the
testsuite now runs cleanly with this version too.
2019-02-05: wsfulton
#1437 SWIG now classifies the status of target languages into either 'Experimental' or
'Supported'. This status is provided to indicate the level of maturity to expect when using
a particular target language as not all target languages are fully developed. Details are
in the Introduction.html chapter of the documentation.

[Python] Documentation enhancements for Python:
#728 Fixed the handling of autodoc when using -fastproxy.
#1367 Added documentation to wrapped member variables using the
property(... doc="...") construct.
Only show a single documentation entry for functions with default arguments when
using autodoc.
Fixed a bug where a cached doxygen docstring could be deleted while still in use,
causing swig to segfault.
2019-01-31: olly
SWIG now requires a target language to be specified instead of
defaulting to wrapping for Tcl. Specifying swig --help without
a target language now just shows the generic help. The -nolang
option has been removed.

2019-01-19: vadz
#1272, #1421 When a function's parameter is a keyword, the name of the paramater is
no longer simply changed to argN, where N is the argument number. Instead the
parameter name is changed to the renaming rules for keywords that normally apply to
symbols such as classes/functions etc. Note that unlike other symbol renaming,
parameter renaming does not issue a warning when the parameter is renamed. This
change only affects languages where the parameter names are actually used, for example,
Java function parameter lists in the proxy class or Python documentation comments.

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.

[OCaml] #1403 #1194 Fix compilation problems for OCaml >= 4.03.0 due to OCaml using

#948 #1019 #1273 Fix for C++11 raw strings where the delimiters were mistakenly left
in the string contents in situations where the string was copied into generated code.
For example, %constant, the "docstring" feature and for C#/Java/D constants turned on
with %javaconst/%csconst/%dmanifestconst.
2019-01-05: wsfulton
[Ruby] #538. Fix Ruby support for %feature("docstring").
2019-01-03: wsfulton
#1202 Fix overloading of non-pointer class types in scripting languages when overloaded
with a pointer and a NULL scripting language equivalent is used, eg None in Python.
The implementation changes the SWIGTYPE, SWIGTYPE& and SWIGTYPE&& typecheck typemaps to
prevent accepting a conversion to a NULL pointer.
2019-01-03: ZackerySpytz
[OCaml] #1386 Fix the OCaml examples and test suite for out-of-source builds.
2019-01-01: wsfulton
[Python] #639 remove duplicate proxy method definitions for global function wrappers.
Global functions previously generated two definitions, eg:
def foo():
return _example.foo()
foo = _example.foo
The first definition is replaced by the second definition and so the second definition
is the one used when the method is actually called. Now just the first definition is
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.

[Java] #1334 Set Java thread name to native thread name when using directors.
Default is to use name "Thread-XXX" and is still works like this by default. However,

Fixes SystemError: Objects/tupleobject.c:81: bad argument to internal function"
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.

[Python] #1368 #1369 Access Violation in tp_print caused by mismatched Python/extension
CRT usage
Remove all use of tp_print, as this API uses a FILE*, which can be
mismatched when modules are built with different C libraries from
the main python executable.
This change also brings consistent output between Python 2 and 3 for the 'cvar' SWIG
object (that contains the global variables) and SWIG packed objects (such as callback
constants).

[Python] #1360 Leak of SWIG var link object
Fix reference counting on _SWIG_globals to allow var link to be freed on module unload.
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.

#1358 Fix handling of abstract base classes nested inside templates
Correct detecting of whether a derived class method overrides a pure virtual
base class method when both classes are nested inside a template class: this
notably didn't work correctly for methods taking parameters of the base class
type.

[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.

#1340 Remove -cppcast and -nocppcast command line options (this was an option
available to the scripting language targets).
The -cppcast option is still turned on by default. The -nocppcast option
to turn off the use of c++ casts (const_cast, static_cast etc) has been
removed. However, defining SWIG_NO_CPLUSPLUS_CAST will still generate C casts
instead of C++ casts for C++ wrappers.

[Python] #1340 Remove -outputtuple and -nooutputtuple command line options.
Both the command line and %module options of the same name have been
removed. These were undocumented. The -outputtuple option returned a
Python tuple instead of a list, mostly typically in the OUTPUT
typemap implementations.
It unclear why a tuple instead of a list return type is needed and
hence this option has been removed as part of the simplification of
the SWIG Python command line options for SWIG 4.

[Python] #1340 Remove -noproxyimport command line option.

[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
-nofastproxy
-nofastquery
-nomodern
-nomodernargs
-nooutputtuple
-nosafecstrings
-old_repr
-oldrepr
-proxydel
-new_vwm is no longer supported. Use the -newvwm alias instead.

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).

Fix #1063. Add using declarations to templates into typedef table.
Using declarations to templates were missing in SWIG's internal typedef tables.
This led to a few problems, such as, templates that did not instantiate and generated

in. This happened mostly when a using declaration was used on a template type in a
completely unrelated namespace.

namespace Space5 {

struct F {};
}
}
using namespace SubSpace5;
using SubSubSpace5::F;
void func(SubSubSpace5::F f);
}
2017-08-16: wsfulton
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

%typemap("in") XXX<int>::Long "..."
template typename<T> struct XXX {

[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.
Fixes SF bug #1208 (3441262) and SF patch #303.

[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
the mkoctfile program supplied by Octave to compile the SWIG-generated
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

[PHP] Add support for PHP7. PHP5's C extension API has changed
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:
ln -s php php5

[PHP] Only emit one copy of each distinct arginfo. Previously we
emitted a separate one for every wrapped function, but typically
many functions have the same number of parameters and combinations
of parameters passed by reference or not.
This change significantly reduces both the size of the generated
wrapper, and of the compiled PHP extension module (e.g. by ~6% for
the stripped extension module for Xapian's PHP7 bindings).

Fix %rename override of wildcard %rename for templates. For example:
%rename(GlobalIntOperator) *::operator bool; // wildcard %rename

OR
%rename(XIntOperator) X<int>::operator bool; // fix now overrides first %rename above
template<typename T> struct X {
operator bool();
...
};
%template(Xint) X<int>;
This also fixes %rename override of global %rename for templates. For example:
// Global rename to make all functions start with a lower case letter
%rename("%(firstlowercase)s", %$isfunction ) "";
%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 */

Hence the overloaded __getitem__ method can be used to support both mp_subscript and sq_item slots.

Patch #730 - Fix %implicitconv for overloaded functions when using

The result is that in all overload cases where there are multiple possibilities

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.

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] Patch #612 - Add support for Python's implicit namespace packages.
2016-05-23: wsfulton
[Ruby] Fix #602 - Error handling regression of opaque pointers introduced
in swig-3.0.8 when C functions explicitly reset a pointer using 'DATA_PTR(self) = 0'.
An ObjectPreviouslyDeleted error was incorrectly thrown when the pointer was used
as a parameter.

[Ruby] Patch #582 - add support for docstring option in %module()
2016-05-14: wsfulton
Fix #434 - Passing classes by value as parameters in director methods did not create
a copy of the argument leading to invalid memory accesses if the object was used
after the upcall into the target language. Passing arguments by value shouldn't give
rise to these sorts of memory problems and so the objects are now copied and ownership
of their lifetime is controlled by the target language.

[Java] unsigned long long marshalling improvements when a negative number
is passed from Java to C. A cast to signed long long in the C layer will now

Fixes #623.
2016-03-22: alexwarg
[Lua] #398 Fix lua __getitem + inheritance
The new handling of classes in Lua (not merging methods into the derived classes)
breaks for classes that provide a __getitem function. The __getitem function
prevents method calls to any method defined in a base class. This fix calls
__getitem only if the member is not found using recursive lookup.

2016-03-12: wsfulton
[Java, C#, D] Fix static const char member variables wrappers with %javaconst(1)
%csconst(1) or %dmanifestconst.
This fixes the case when an integer is used as the initializer, such as:
struct W { static const char w = 100; };
Fix generated code parsing enum values using char escape sequences
when these values appear in the Java code (usually when using %javaconst(1))
such as:
enum X { x1 = '\n', x2 = '\1' };
Similarly for static const member char variables such as:
struct Y { static const char y = '\n'; }
Likewise for D and %dmanifestconstant. For C# and %csconst(1), char
values in C# are now hex escaped as C# doesn't support C octal escaping.
2016-03-11: wsfulton
[Java C#] Add support for treating C++ base classes as Java interfaces
instead of Java proxy classes. This enable some sort of support for
multiple inheritance. The implementation is in swiginterface.i and
provides additional macros (see Java.html for full documentation):
%interface(CTYPE)
%interface_impl(CTYPE)
%interface_custom("PROXY", "INTERFACE", CTYPE)
2016-03-01: wsfulton
Add rstrip encoder for use in %rename. This is like the strip encoder but
strips the symbol's suffix instead of the prefix. The example below
will rename SomeThingCls to SomeThing and AnotherThingCls to AnotherThing:
%rename("%(rstrip:[Cls])s") "";
class SomeThingCls {};
struct AnotherThingCls {};

[Go] Ensure structs are properly packed between gc and GCC/clang.
2016-01-25: ahnolds
[Python] Support the full Python test suite in -classic mode
* Convert long/unsigned long/long long/unsigned long long to PyInt
rather than PyLong when possible. Certain python functions like
len() require a PyInt when operating on old-style classes.
* Add support for static methods in classic mode, including support
for pythonappend, pythonprepend, and docstrings.
* Removing the use of __swig_getmethods__ for static member methods
since they will always be found by the standard argument lookup
* Fix a bug where the wrong type of exception was caught when
checking for new-style class support
2016-01-23: ahnolds
[Go] Enable support for the Go test-suite on OSX:
* The linker on OSX requires that all symbols (even weak symbols)
are defined at link time. Because the function _cgo_topofstack is
only defined starting in Go version 1.4, we explicitly mark it as
undefined for older versions of Go on OSX.
* Avoid writing empty swigargs structs, since empty structs are not
allowed in extern "C" blocks.

Improved size_t and ptrdiff_t typemaps to support large values
on platforms where sizeof(size_t) > sizeof(unsigned long) and
sizeof(ptrdiff_t) > sizeof(long).

The pdf documentation is now generated by wkhtmltopdf and has colour

2015-12-23: ahnolds
[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.
2015-12-19: wsfulton
[Python] Python 2 Unicode UTF-8 strings can be used as inputs to char * or
std::string types if the generated C/C++ code has SWIG_PYTHON_2_UNICODE defined.
2015-12-17: wsfulton
Issues #286, #128
Remove ccache-swig.1 man page - please use the CCache.html docs instead.
The yodl2man and yodl2html tools are no longer used and so SWIG no
longer has a dependency on these packages which were required when
building from git.
2015-12-16: zturner/coleb
[Python] Fix Python3.5 interpreter assertions when objects are being
deleted due to an existing exception. Most notably in generators
which terminate using a StopIteration exception. Fixes #559 #560 #573.
If a further exception is raised during an object destruction,
PyErr_WriteUnraisable is used on this second exception and the
original exception bubbles through.

Fix STL wrappers to not generate <: digraphs.
For example std::vector<::X::Y> was sometimes generated, now
corrected to std::vector< ::X::Y >.
2015-11-25: wsfulton
[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
2015-11-21: wsfulton
[Ruby, Python] Add std::array container wrappers.
These work much like any of the other STL containers except Python/Ruby slicing
is somewhat limited because the array is a fixed size. Only slices of
the full size are supported.

2015-09-13: kkaempf
[Ruby] Resolve tracking bug - issue #225.
The bug is that the tracking code uses a ruby hash and thus may
allocate objects (Bignum) while running the GC. This was tolerated in
1.8 but is invalid (raises an exception) in 1.9.
The patch uses a C hash (also used by ruby) instead.

[Go] Removed golang stringing for signed/unsigned char
Changed default handling of signed char* and unsigned char* to be
opaque pointers rather than strings, similarly to how other

Any existing code relying on treating signed char* or unsigned

using %apply to copy the [unchanged] char* behavior.

2015-08-02: wsfulton
[Java] Fix potential security exploit in generated Java classes.
The swigCPtr and swigCMemOwn member variables in the generated Java
classes are now declared 'transient' by default. Further details of the exploit
in Android is being published in an academic paper as part of USENIX WOOT '15:
https://www.usenix.org/conference/woot15/workshop-program/presentation/peles.
In the unlikely event that you are relying on these members being serializable,
then you will need to override the default javabody and javabody_derived typemaps
to generate the old generated code. The relevant typemaps are in the Lib directory
in the java.swg, boost_shared_ptr.i and boost_intrusive_ptr.i files. Copy the
relevant default typemaps into your interface file and remove the 'transient' keyword.

[Python] Improve indentation warning and error messages for code in the following directives:
%pythonprepend

Old error example:
Error: Line indented less than expected (line 3 of pythoncode)
New error example:
Error: Line indented less than expected (line 3 of %pythoncode or %insert("python") block)
as no line should be indented less than the indentation in line 1
Old warning example:
Warning 740: Whitespace prefix doesn't match (line 2 of %pythoncode or %insert("python") block)
New warning example:
Warning 740: Whitespace indentation is inconsistent compared to earlier lines (line 3 of
%pythoncode or %insert("python") block)
2015-07-28: wsfulton
[Python] Fix #475. Improve docstring indentation handling.
SWIG-3.0.5 and earlier sometimes truncated text provided in the docstring feature.
This occurred when the indentation (whitespace) in the docstring was less in the
second or later lines when compared to the first line.
SWIG-3.0.6 gave a 'Line indented less than expected' error instead of truncating
the docstring text.
Now the indentation for the 'docstring' feature is smarter and is appropriately
adjusted so that no truncation occurs.
2015-07-22: wsfulton
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"
2015-07-22: lindleyf
Apply patch #439 - support for $typemap() (aka embedded typemaps or special variable
macros) in typemap attributes. A simple example where $typemap() is expanded in the
'out' attribute (C# specific):
%typemap(cstype) unsigned int "uint"
%typemap(cstype, out="$typemap(cstype, unsigned int)") unsigned int& "$typemap(cstype, unsigned int)"
is equivalent to:
%typemap(cstype, out="uint") unsigned int& "uint"

SWIG no longer generates a wrapper for a class' constructor if that class has
any base class with a private destructor. This is because your compiler should
not allow a class to be instantiated if a base has a private destructor. Some
compilers do, so if you need the old behaviour, use the "notabstract" feature, eg:
%feature("notabstract") Derived;
class Base {
~Base() {}
};
struct Derived : Base {};

2015-05-28: wsfulton
[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.

===========================
2014-03-16: wsfulton
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 http://www.swig.org/Doc3.0/CPlusPlus11.html.

[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.

[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.

[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.

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

[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] 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

2013-02-19: 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".

Deprecate typedef names used in %extend that are not the real class/struct name. For example:
typedef struct StructBName {

%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

%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

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:

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

2012-10-10: wsfulton
Additional new special variables in %exception are expanded as follows:
