This project automatically generates ctypes wrappers for header files written in C.

For example, if you'd like to generate Neon bindings, you can do so using this recipe:

$ python ctypesgen.py -lneon /usr/local/include/neon/ne_*.h -o neon.py

Some libraries, such as APR, need special flags to compile. You can pass these flags in on the command line.

For example:

$ FLAGS = `apr-1-config --cppflags --includes`
$ python ctypesgen.py $FLAGS -llibapr-1.so $HOME/include/apr-1/apr*.h -o apr.py

Sometimes, libraries will depend on each other. You can specify these dependencies using -mmodule, where module is the name of the dependency module. Here's an example for apr_util:

$ python ctypesgen.py $FLAGS -llibaprutil-1.so $HOME/include/apr-1/ap[ru]*.h -mapr -o apr_util.py

If you want JSON output (e.g. for generating Lua bindings), use --output-language=json. When outputting JSON, you will probably want to use --all-headers --builtin-symbols --no-stddef-types --no-gnu-types --no-python-types too.
