Generic code generator from WebIDL interfaces.
pywidl parses WebIDL code using PLY, builds the interface object model and emits whatever code using user's mako templates or even user's native python module.
Installing with pip:
pip install pywidl
gentoo users may use odin overlay:
emerge pywidl
Defined in pywidl/model.py
Common usage in tests/idl.py
m4 script may be useful for you.
You may find m4 usage example in libcssom project.
