35 ## Alternative solution
37 [Here](http://www.jk.fr.eu.org/ikiwiki/format-escapes-2.diff) is a patch
38 largely inspired from the one below, which is up to date and written with
39 [[todo/multiple_output_formats]] in mind. "htmlize" hooks are generalized
40 to "convert" ones, which can be registered for any pair of filename
43 Preprocessor directives are allowed to return the content to be inserted
44 as a hash, in any format they want, provided they provide htmlize hooks for it.
45 Pseudo filename extensions (such as `"_link"`) can also be introduced,
46 which aren't used as real extensions but provide useful intermediate types.

61 * Fix tags to page names that contain special characters.
62 + * Based on a patch by Ethan, add a new htmlescape hook, that is called
63 + when a preprocssor directive emits inline html. The rst plugin uses this
64 + hook to support inlined raw html.
67 * Use pngcrush and optipng on all PNG files.

167 Note that this plugin does not interoperate very well with the rest of
168 ikiwiki. Limitations include:
170 -* reStructuredText does not allow raw html to be inserted into
171 - documents, but ikiwiki does so in many cases, including
172 - [[WikiLinks|WikiLink]] and many
173 - [[PreprocessorDirectives|PreprocessorDirective]].
174 +* Some bits of ikiwiki may still assume that markdown is used or embed html
175 + in ways that break reStructuredText. (Report bugs if you find any.)
176 * It's slow; it forks a copy of python for each page. While there is a
177 perl version of the reStructuredText processor, it is not being kept in
178 sync with the standard version, so is not used.
