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. ... read more

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.

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
    features: http://www.swig.org/Doc3.0/CPlusPlus11.html
  • 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.

SWIG license explanation

We have recently updated the SWIG legal page to provide clarification on the SWIG license. There has been some confusion as to how the GPL license may or may not affect the code generated by SWIG. Please take a look at the updated SWIG legal page.

We are indebted to the Software Freedom Law Center for all the help given in providing the legal explanations and for originally helping set up the license for version 2.0.

SWIG on Github

With the new year we have switched SWIG development to a new development model - Git on Github. The old Subversion history (including the even older CVS history) has been migrated and is now viewable in Github - https://github.com/swig/swig. If you have used SWIG we would really appreciate improvements you have made for incorporation into the mainline SWIG releases. So, feel free to use Github to fork and send your pull requests or patches.... read more

Summer of Code 2012

GSoC 2012 was SWIG's third Summer of Code, and this year we
received five slots for projects related to SWIG. Out of five,
four students completed the program successfully with valuable
additions to SWIG.

Dmitry Kabak, mentored by Marko Klopcic, worked on SWIG
internals to parse the source code documentation comments within
the C/C++ header files and use them to document the target
language wrapper classes/functions. Dmitry's efforts
complemented the existing support added in GSoC 2008. In
summary, all previously known bugs have been fixed and the
original source code for comment translation was re-factored to
improve performance and maintainability. Parsing of C/C++ source
code has been improved, so that every declaration/definition can
now be commented. Translation of Doxygen tags to Javadoc and
Python docstrings has been improved and corresponding regression
tests have been implemented. The project mentor, Marko Klopcic
has some great ideas for the future GSoC. The work can be tried
out on the branch gsoc2012-doxygen.... read more
