# Very simple reStructuredText processor.
|
|
#
|
|
# This plugin calls python and requires python-docutils to transform the text
|
|
# into html.
|
|
#
|
|
# Its main problem is that it does not support ikiwiki's WikiLinks nor
|
|
# Preprocessor Directives.
|
|
#
|
|
# Probably Wikilinks and Preprocessor Directives should support a list of
|
|
# extensions to process (i.e. the linkify function could be transformed into
|
|
# reStructuredText instead of HTML using a hook on rst.py instead of the
|
|
# current linkify function)
