PyFFI 2.2.3

Processing block structured binary files.

The Python File Format Interface, briefly PyFFI, is an open source Python library for processing block structured binary files:

• Simple: Reading, writing, and manipulating complex binary files in a Python environment is easy! Currently, PyFFI supports the NetImmerse/Gamebryo NIF and KFM formats, CryTek’s CGF format, the FaceGen EGM format, the DDS format, and the TGA format.

• Batteries included: Many tools for files used by 3D games, such as optimizers, stripifier, tangent space calculator, 2d/3d hull algorithms, inertia calculator, as well as a general purpose file editor QSkope (using PyQt4), are included.

• Modular: Its highly modular design makes it easy to add support for new formats, and also to extend existing functionality.

Download

Get PyFFI from Github, or install it with:

easy_install -U PyFFI

or:

pip3 install PyFFI

Developing

To get the latest (but possibly unstable) code, clone PyFFI from its Git repository:

git clone --recursive git://github.com/niftools/pyffi.git
virtualenv -p python3 venv
source venv/bin/activate
pip install -r requirements-dev.txt

Be sure to use the –recursive flag to ensure that you also get all of the submodules.

If you wish to code on PyFFI and send your contributions back upstream, get a github account and fork PyFFI.

Testing

We love tests, they help guarantee that things keep working they way they should. You can run them yourself with the following:

source venv/bin/activate
nosetest -v test

or:

source venv/bin/activate
py.test -v tests

Documentation

All our documentation is written in ReST and can be generated into HTML, LaTeX, PDF and more thanks to Sphinx. You can generate it yourself:

source venv/bin/activate
cd docs
make html -a

Examples

• The Blender NIF Plugin

• QSkope PyFFI’s general purpose file editor.

• The niftoaster (PyFFI’s “swiss army knife”) can for instance optimize NIF files, and much more.
