Demo 3

For a more realistic example of this recipe in action, let's look at using the nuklear GUI library from Python. Here's the header:

cd ../nuklear-cffi
vim nuklear/nuklear.h

It's huge!

But it's plain C, so it's very simple and we can build and parse it just the same as we did before.

vim build.py

As you can see, it's no longer than our other build script.

Here's the call site:

vim demo/overview.py

It's a direct port of the overview.c demo from the nuklear repo. As you can see, it is very long!

python2 demo/demo.py

There you have it! Can you imagine writing and maintaining a binding for that API by hand? Yes, it would probably produce a nicer interface, but it would take a lot of effort! Worse is better.
