A plugin system should ideally support things like:
* [[todo/lists]] of pages, of mising pages / broken links, of registered users, etc
* a [[todo/link_map]]
-* [[todo/sigs]]
* [[pageindexes]]
* Wiki stats, such as the total number of pages, total number of links, most linked to pages, etc, etc.
* wiki info page, giving the ikiwiki version etc
* would it be useful to reimplement the hyperestradier search integration as a plugin?
+* Support [[RecentChanges]] as a regular page containing a plugin that updates each time there is a change, and statically builds the recent changes list. (Would this be too expensive/inflexible? There might be other ways to do it as a plugin, like making all links to RecentChanges link to the cgi and have the cgi render it on demand.)
* etc
+* For another type of plugin, see [[todo/PluggableRenderers]].
-Another, separate plugin system that already (mostly) exists in ikiwiki is the RCS backend, which allows writing modules to drive other RCS systems than subversion.

## preprocessor plugins
-Considering ikiwiki plugins, one idea I have is to make the [[PreProcessorDirective]]s be a plugin. A setting in the config file would enable various plusins, which are perl modules, that each provide one or more preprocessor directives.
-
-Since preprocessing happens before htmlization but after a page is loaded and linkified, it should be possible to use it to create something like a link map or lists, or a page index. Page inlining and rss generation is already done via preprocessor directives and seems a natureal as a plugin too.
-
-Note that things like a link map or a broken link list page would need to be updated whenever a set (or all) pages change; the %inlinepages hash already allows for pages to register this, although it might need to be renamed.
-
-I need to look at the full range of things that other wikis use their plugin systems for, but preprocessor directives as plugins certianly seems useful, even if it's not a complete solution.

## case study: Moin Moin plugins
* *parsers* and *formatters* are basically what I've been calling [[PluggableRenderers]]. MoinMoin separates these, so that a page is parsed to (presumbly) some intermediate form before being output as html or some other form. That's a nice separation, but what to do about things like markdown that are both a parser and a formatter?
* *macros* and *processors* are analagous to preprocessor directives. A processor can operate on a large block of text though.
* *themes* should be irrellevant (ikiwiki has [[templates]]).
