It's far from perfect released, but API should become more or less stable starting with this release, and NS-3 is using this code with success. Also most features that I need are there.
Oh, and here's the NEWS related to this release:
=== pybindgen 0.9 ===
- Fix GCC 4.2 compilation warnings;
- Works with some GCCXML 0.9/cvs snapshots (tested with 2008-04-20),
in addition to stable 0.7;
- Support for overloaded virtual methods;
- Add 'ignore' annotation support, allowing to ignore functions
and methods;
- Generally work hard to make sure the generated code at least
always compiles, even if we have to disable generation of
certain wrappers;
- Add support for protected methods and constructors;
- Preliminary support for templated classes/methods/functions;
- Add more type conversions, such as uint64_t and uint16_t;
- Support implicit conversions also for pass-by-reference parameters;
- Add supported for nested (i.e. defined inside a class) enums and classes;
- Add support for adding manually written custom method or function wrappers;
- Split the gccxmlparser.ModuleParser.parse() method into several
smaller methods, to allow greater customization and flexibility;
- Add support for customising C++ class instance creation code;
- Much improved support for wrapping pure C code;
- Support std::ostream << myobject mapped as str(myobject) (Mathieu Lacage)
- Support default values in parameters;
- More intuitive API (thanks Mathieu Lacage for feedback)
- Support generation of a Python pybindgen script from scanned API;
- Support splitting of generated python script and/or C/C++ module into several files;
- Lots of small bug fixes, and other features I probably forgot;
- New tutorial (thanks Mathieu Lacage), and API docs.
