I'd like to see some way to include certain files from the underlay only when the wiki has certain plugins enabled. For example: * Only include smileys.mdwn and the smileys subdirectory if you enable the [[plugins/smiley]] plugin. * Exclude openid.mdwn if you disable the [[plugins/openid]] plugin. * Include shortcuts.mdwn only if you enable the [[plugins/shortcut]] plugin. * Include blog.mdwn only if you don't disable the [[plugins/inline]] plugin. * Include favicon.ico only if you enable the [[plugins/favicon]] plugin. * Include wikiicons/diff.png (and the wikiicons directory) only if you enable the CGI. * Include a hypothetical restructuredtexthelp.rst or similar for other formats only with those formats enabled. I can see two good ways to implement this. Ideally, with [[conditional_text_based_on_ikiwiki_features]] available, ikiwiki could parse a page like conditionalpages.mdwn, which could contain a set of conditional-wrapped page names; that seems like the most elegant and ikiwiki-like approach. Alternatively, ikiwiki.setup could contain a Perl-generated exclude option by default; that would work, but it seems hackish. > Another way might be to have a third directory of source files where > plugins could drop in pages, and only build the files from there if their > plugins were enabled. > > Using the conditionals in a page to control what other pages get built > feels complex to me. > > Instead, this has been implmented as the `add_underlay()` function. > [[done]] > --[[Joey]]
