Welcome to SWIG
[ Chinese ]
SWIG is a software development tool that connects programs written in
C and C++ with a variety of high-level programming
languages. SWIG is used with different types of target languages including common scripting languages such as
supported languages also includes
non-scripting languages such as C#, Common Lisp (CLISP, Allegro CL, CFFI, UFFI), D, Go language,
Java including Android, Lua, Modula-3, OCAML, Octave, Scilab and R.
Also several interpreted and compiled Scheme implementations (Guile, MzScheme/Racket, Chicken)
are supported. SWIG is most
commonly used to create high-level interpreted or compiled programming
environments, user interfaces, and as a tool for testing and prototyping C/C++ software.
SWIG is typically used to parse C/C++ interfaces and generate the 'glue code' required for the above target languages to call into the C/C++ code.
SWIG can also export its parse tree in the form of XML and Lisp s-expressions.
SWIG is free software and the code that SWIG generates is compatible with both commercial and non-commercial projects.

* Minor new features and bug fixes.
- 2015/07/05 - SWIG-3.0.6 released
SWIG-3.0.6 is mostly a stability release.
- Stability and regression fixes.
- Fixed parsing of C++ corner cases.

- 2015/03/07 - Defending the GPL
SWIG is a proud member of the Software Freedom Conservancy who has recently announced that they will be supporting a lawsuit to defend an alleged violation of the GNU General Public License (GPL). Ensuring this software license, the same one that protects the SWIG source code, is not abused and is actively defended in a court of law is important for everyone using the license.
Conservancy is supporting Christoph Hellwig's lawsuit against VMware over GPL violations on Linux. VMware have stated that they would not comply with the GPL after many patient years of negotiations by Christoph and the Conservancy. More information is in the Conservancy's FAQ on the lawsuit.
If you have benefited or enjoyed the fruits of SWIG, it is because the SWIG developer's chose to use a software license to ensure it remains freely available. Please consider supporting Christoph and Conservancy including their fund raising appeal to defend our license.

- 2015/02/01 - SWIG-3.0.5 released
We are pleased to announce SWIG-3.0.5 has been released with the addition of support for Scilab.
This version also contains:
- An important Python fix for a regression in SWIG-3.0.3 when wrapping C++ default arguments.
- Minor improvements for C#, Go, Octave, PHP and Python.
SWIG-3.0.4 was also released recently and contained part of the Python fix for the regression mentioned above. Python users should definitely rather use 3.0.5.
- 2014/12/31 - SWIG-3.0.3 released
SWIG-3.0.3 release summary:
- Add support for C++11 strongly typed enumerations.
- Numerous bug fixes and minor enhancements for C#, D, Go, Java,
More detailed release notes can be seen at http://swig.org/release.html
- 2014/06/04 - SWIG-3.0.2 released
This release has been made to fix a bug during installation, but it also includes a couple of other rather minor changes.
- 2014/05/27 - SWIG-3.0.1 released
- A few notable regressions introduced in 3.0.0 have been fixed - in Lua, nested classes and parsing of operator <<.
- The usual round of bug fixes and minor improvements for C#, GCJ, Go, Java, Lua, PHP and Python.
- 2014/03/16 - SWIG-3.0.0 released
This is a major new release focusing primarily on C++ improvements.
- C++11 support added. Please see documentation for details of supported
- Nested class support added. This has been taken full advantage of in
Java and C#. Other languages can use the nested classes, but require
further work for a more natural integration into the target language.
We urge folk knowledgeable in the other target languages to step
forward and help with this effort.
- Lua: improved metatables and support for %nspace.
- Go 1.3 support added.
- Python import improvements including relative imports.
- Python 3.3 support completed.
- Perl director support added.
- C# .NET 2 support is now the minimum. Generated using statements are
replaced by fully qualified names.
- Bug fixes and improvements to the following languages:
C#, Go, Guile, Java, Lua, Perl, PHP, Python, Octave, R, Ruby, Tcl
- Various other bug fixes and improvements affecting all languages.
- Note that this release contains some backwards incompatible changes
in some languages.
- Full detailed release notes are in the changes file.
- 2014/02/09 - SWIG-2.0.12 released
- This is a maintenance release backporting some fixes from the pending 3.0.0 release.
- Octave 3.8 support added.
- C++11 support for new versions of erase/insert in the STL containers.
- Compilation fixes on some systems for the generated Lua, PHP, Python and R wrappers.
- 2013/09/15 - SWIG-2.0.11 released
- Minor bug fixes and enhancements mostly in Python, but also
C#, Lua, Ocaml, Octave, Perl, PHP, Python, R, Ruby, Tcl.
