Doxygen XML to SWIG docstring converter (improved version)

doxy2swig (improved)

Doxygen XML to SWIG docstring converter (improved version).

Converts Doxygen generated XML files into a file containing docstrings for use by SWIG.

Usage

1. 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).

2. Run doxygen to extract the documentation and output it in XML format.

3. 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
   

4. Include the docstring file generated by doxy2swig.py at the top of your swig file using %include output.i.

Note

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.
