"""Attempt to generate templates for module reference with Sphinx
|
|
|
|
XXX - we exclude extension modules
|
|
|
|
To include extension modules, first identify them as valid in the
|
|
``_uri2path`` method, then handle them in the ``_parse_module`` script.
|
|
|
|
We get functions and classes by parsing the text of .py files.
|
|
Alternatively we could import the modules for discovery, and we'd have
|
|
to do that for extension modules. This would involve changing the
|
|
``_parse_module`` method to work via import and introspection, and
|
|
might involve changing ``discover_modules`` (which determines which
|
|
files are modules, and therefore which module URIs will be passed to
|
|
``_parse_module``).
|
|
|
|
NOTE: this is a modified version of a script originally shipped with the
|
|
PyMVPA project, which we've adapted for NIPY use. PyMVPA is an MIT-licensed
|
|
project."""
