Since some preprocessor directives insert raw HTML, it would be good to
specify, per-format, how to pass HTML so that it goes through the format
OK. With Markdown we cross our fingers; with reST we use the "raw"
directive.
I added an extra named parameter to the htmlize hook, which feels sort of
wrong, since none of the other hooks take parameters. Let me know what
you think. --Ethan
Seems fairly reasonable, actually. Shouldn't the $type come from $page
instead of $destpage though? Only other obvious change is to make the
escape parameter optional, and only call it if set. --[[Joey]]
I couldn't figure out what to make it from, but thinking it through,
yeah, it should be $page. Revised patch follows. --Ethan
I've updated the patch some more, but I think it's incomplete. ikiwiki
emits raw html when expanding WikiLinks too, and it would need to escape
those. Assuming that escaping html embedded in the middle of a sentence
works.. --[[Joey]]
Revised again. I get around this by making another hook, htmlescapelink,
which is called to generate links in whatever language. In addition, it
doesn't (can't?) generate
spans, and it doesn't handle inlineable image links. If these were
desired, the approach to take would probably be to use substitution
definitions, which would require generating two bits of code for each
link/html snippet, and putting one at the end of the paragraph (or maybe
the document?).
To specify that (for example) Discussion links are meant to be HTML and
not rst or whatever, I added a "genhtml" parameter to htmllink. It seems
to work -- see http://ikidev.betacantrips.com/blah.html for an example.

Alternative solution
Here is a patch
largely inspired from the one below, which is up to date and written with
[[todo/multiple_output_formats]] in mind. "htmlize" hooks are generalized
to "convert" ones, which can be registered for any pair of filename
extensions.
Preprocessor directives are allowed to return the content to be inserted
as a hash, in any format they want, provided they provide htmlize hooks for it.
Pseudo filename extensions (such as "_link") can also be introduced,
which aren't used as real extensions but provide useful intermediate types.

Wow, this is in many ways a beautiful patch. I did notice one problem,
if a link is converted to rst and then from there to a hyperlink, the
styling info usially added to such a link is lost. I wonder if it would
be better to lose _link stuff and just create link html that is fed into
the rst,html converter. Other advantage to doing that is that link
creation has a rather complex interface, with selflink, attrs, url, and
content parameters.
--[[Joey]]
Thanks for the compliment. I must confess that I'm not too familiar with
rst. I am using this todo item somewhat as a pretext to get the conversion
stuff in, which I need to implement some other stuff. As a result I was
less careful with the rst plugin than with the rest of the patch.
I just updated the patch to fix some other problems which I found with
more testing, and document the current limitations.
Rst cannot embed raw html in the middle of a paragraph, which is why
"_link" was necessary. Rst links are themselves tricky and can't be made to
work inside of words without knowledge about the context.
Both problems could be fixed by inserting marks instead of the html/link,
which would be replaced at a later stage (htmlize, format), somewhat
similiar to the way the toc plugin works. When I get more time I will
try to fix the remaining glitches this way.
Also, I think it would be useful if ikiwiki had an option to export
the preprocessed source. This way you can use docutils to convert your
rst documents to other formats. Raw html would be loosed in such a
process (both with directives and marks), which is another
argument for "_link" and other intermediate forms. I think I can
come up with a way for rst's convert_link to be used only for export
purposes, though.
--[[JeremieKoenig]]
Another problem with this approach is when there is some html (say a
table), that contains a wikilink. If the link is left up to the markup
lamguage to handle, it will never convert it to a link, since the table
will be processed as a chunk of raw html.
