How to contribute

Do you want to fix a bug, improve documentation, or add a new feature?

Get git/msysgit

If you are on windows, you need msysgit. If you are already familiar with subversion, then, in a nutshell, msysgit is for git what TortoiseSVN is for subversion. The main difference is that msysgit is a command line based tool.

For more information about git and github, the github help site is a great start.

Track the source

If you simply want to keep track of the latest source code, start a shell (or, the Git Bash on windows), and type (this is like “svn checkout”):

git clone git://

To synchronize your code, type (this is like “svn update”):

git pull


Create a fork

Use the source

PyFFI is entirely written in pure Python, hence the source code runs as such on any system that runs Python. Edit the code with your favorite editor, and install your version of PyFFI into your Python tree to enable your PyFFI to be used by other applications such as for instance QSkope, or the Blender NIF Scripts. From within your PyFFI git checkout:

C:\Python25\python.exe install

or on linux:

python install

To build the documentation:

cd docs-sphinx
make html

PyFFI has an extensive test suite, which you can run via:


The Blender NIF Scripts test suite provides additional testing for PyFFI. From within your niftools/blender checkout:

blender -P

To build the source packages and the Windows installer (on a linux system which has both wine and nsis installed):

Submit your updates

Simply do a pull request if you want your fork to be merged, and your contributions may be included in the next release!
