Doxygen XML to SWIG docstring converter (improved version).
Converts Doxygen generated XML files into a file containing docstrings for use by SWIG.
As of swig 4.0.0, direct support for parsing and conversion of doxygen documentation is available, and according to the swig documentation can be enabled via swig -python -doxygen
(perhaps in conjunction with %feature("autodoc", "1")
). It is still possible to generate and include docstrings via doxy2swig
as described below, but this should no longer be required and is considered deprecated.
-
Set doxygen to generate XML output by adding
GENERATE_XML = YES
to the project doxygen configuration file (or create a seperate one for this purpose). -
Run doxygen to extract the documentation and output it in XML format.
-
Use doxy2swig.py to convert the XML documentation to doctrings for SWIG
doxy2swig.py [options] index.xml output.i index.xml is your doxygen generated XML file and output.i is where the output will be written (the file will be clobbered). Options: -h, --help show this help message and exit -f, --function-signature include function signature in the documentation. This is handy when not using swig auto-generated function definitions %feature("autodoc", [0,1]) -t, --type-info include type information for arguments in function signatures. This is similar to swig autodoc level 1 -c, --constructor-list generate a constructor list for class documentation. Useful for target languages where the object construction should be documented in the class documentation. -a, --attribute-list generate an attributes list for class documentation. Useful for target languages where class attributes should be documented in the class documentation. -o, --overloaded-functions collect all documentation for overloaded functions. Useful for target languages that have no concept of overloaded functions, but also to avoid having to attach the correct docstring to each function overload manually -w W, --width=W textwidth for wrapping (default: 80). Note that the generated lines may include 2 additional spaces (for markdown). -q, --quiet be quiet and minimize output
-
Include the docstring file generated by doxy2swig.py at the top of your swig file using
%include output.i
.
To attach docstrings to classes with SWIG for python and using the -builtin
option,
a version of SWIG >= 3.0.7 is required.
Without this, the class documentation including constructor lists (-c
) and attribute
lists (-a
) will not be available from python.
