wxPerl, Perl bindings for wxWidgets
Started in 2000 and maintained for more than 10 years by me.
wxWidgets cross-platform GUI toolkit with native look and feel.
I have been member of the development team with commit privileges; I worked on the Motif port towards STL-compatibility for the toolkit.
One of the programming languages i like most.
A nice hack. To compile Perl modules the same compiler with which Perl was compiled is required. With ExtUtils::FakeConfig you can compile modules for ActivePerl on Win32 using the free MinGW GCC compiler.
Started as part of wxPerl and currenly maintained by Steffen Müller, is a preprocessor that takes a C++-like header file and produces output suitable for ExtUtils::ParseXS
Some small projects on GitHub.
