Defcon is a set of UFO based objects optimized for use in font editing applications. The objects are built to be lightweight, fast and flexible. The objects are very bare-bones and they are not meant to be end-all, be-all objects. Rather, they are meant to provide base functionality so that you can focus on your application’s behavior, not object observing or maintaining cached data. Defcon implements UFO3 as described by the UFO font format. If needed, the ufo2-deprecated branch has the older, UFO2, version of Defcon.


To download and install the latest stable release of defcon from the Python Package Index, use the pip command line tool:

pip install --upgrade defcon
