This is a Python script to generate C code to support OO-like interfaces which can then be compiled with gcc. See the docstring in the script for more details. The basic usage is: c_intf_gen.py <interface description file> The abs_factory directory gives a complete example of how this can be used to implement the abstract factory design pattern: http://en.wikipedia.org/wiki/Abstract_factory This script requires Python 2.7+. The motiviation for writing this script is a lot of OO-design principles can be done with just interfaces (i.e., without type inheritance). Many of the GoF Design Patterns can be done with just interfaces and the Go language strongly favors interfaces for OO design. For a good overview of the importance of interfaces: http://www.artima.com/weblogs/viewpost.jsp?thread=274019 Obviously interfaces can be done in C, but it takes a fair amount of "boring", error-prone code to setup all the relationships between structs. So, this attempts to generate most of the "boring" code required to support interfaces to make their usage easier.
