Easily consuming single-header C libraries in Python

This is a presentation I did on a technique I used for consuming single header C libraries from Python in a personal project, utilising the hard work of other people so that I did not have to do any!

Given a single-header dependency with no existing binding, you can easily create (and build, and package) one by feeding the header directly to cffi, with some simple text transformations to remove problematic syntax.

This presentation is a recipe for using the hard work of other people without going to much trouble. Here is that hard work:

• nuklear, a ridiculously impressive GUI library with no dependencies in a single ANSI C header.
• cffi, a foreign function interface library for Python which takes a reduced C syntax as its interface definition language and which can build and package C source code for you.
• pcpp, A C preprocessor written in Python.
