py3c helps you port C extensions to Python 3.

It provides a detailed guide, and a set of macros to make porting easy and reduce boilerplate.

• Reduce chances of accidental subtle errors
• Minimize boilerplate
• Prefer the Python 3 way of doing things
• Minimize semantic changes under Python 2

Projects using py3c will be compatible with CPython 2.6, 2.7, and 3.3+.

A detailed porting guide is provided.

A cheatsheet is available for those that already know the Python C API, and want to know what the py3c macros do.

If your build system supports pkg-config, you can set it up to look for a system-wide installation of py3c.

Alternately, py3c can be used as a header-only library: copy the headers to your project and use them.

If you wish to install py3c system-wide (e.g. if you are a distro packager), read installation.
