# Generating Python docstrings from C++ code using doxygen
#

There are at least two strategies for this:
  - use xsltproc as described below
  - use doxy2swig.py (included in this directory)

FIXME: get one of these working (probably doxy2swig since it doesn't
add any additional dependencies).

I have successfully extracted function/class description from doxygen 
generated xml files, using an xslt script. To add doxygen generated 
description to each class/function, you will need to (tested under 
linux, note that this works only for Python, using Robin's docstring 
patch)

1. download swig source, apply Robin's docstring patch from
   https://sourceforge.net/tracker/index.php?func=detail&aid=1023309&group_id=1645&atid=301645
   compile and install

2. generate doxygen document with option "GENERATE_XML = YES"

3. copy the attached script (save as swig.xsl) to the doc/xml directory 
   and run

     > xsltproc swig.xsl index.xml > temp_doc.i
     > cat temp_doc.i | sed 's/"/\\"/g' | sed 's/__QuOtE__/"/g' > swig_doc.i

   you will get an interface file with lines like
     %feature("docstring") class "class description";
     %feature("docstring") class::function "member function 
         description";

   the second step is necessary since there might be " in descriptions 
   and I need to backquote them before I replace __QuOtE__ by real 
   quotes. (xslt experts may know how to post-process <xsl:value-of> and 
   make the script easier to use.)

4. in your interface file, add
     %include "siwg_doc.i"
     %feature("autodoc","1") ;

Hope this helps.
