Hawkmoth - Sphinx Autodoc for C
Hawkmoth is a minimalistic Sphinx C Domain autodoc directive extension to incorporate formatted C source code comments written in reStructuredText into Sphinx based documentation. It uses Clang Python Bindings for parsing, and generates C Domain directives for C API documentation, and more. In short, Hawkmoth is Sphinx Autodoc for C.
Hawkmoth aims to be a compelling alternative for documenting C projects using Sphinx, mainly through its simplicity of design, implementation and use.
Given C source code with rather familiar looking documentation comments:
/** * Get foo out of bar. */ void foobar();
and a directive in the Sphinx project:
.. c:autodoc:: filename.c
you can incorporate code documentation into Sphinx. It’s as simple as that.
You can document functions, their parameters and return values, structs, unions, their members, macros, function-like macros, enums, enumeration constants, typedefs, variables, as well as have generic documentation comments not attached to any symbols.
Documentation on how to configure Hawkmoth and write documentation comments, with examples, is available in the doc directory in the source tree, obviously in Sphinx format and using the directive extension. Pre-built documentation showcasing what Hawkmoth can do is available at Read the Docs.
You can install Hawkmoth from PyPI with:
pip install hawkmoth
You’ll additionally need to install Clang and Python 3 bindings for it through your distro’s package manager; they are not available via PyPI. You may also need to set LD_LIBRARY_PATH so that the Clang library can be found. For example:
export LD_LIBRARY_PATH=$(llvm-config --libdir)
Alternatively, installation packages are available for:
In Sphinx conf.py, add hawkmoth to extensions, and point cautodoc_root at the source tree. See the extension documentation for details.
