The function is passed named parameters: "page" and "content" and should
return the htmlized content.
+If `hook` is passed an optional "keepextension" parameter, set to a true
+value, then this extension will not be stripped from the source filename when
+generating the page.
+
### pagetemplate
hook(type => "pagetemplate", id => "foo", call => \&pagetemplate);
and undef if a rebuild could be needed in some circumstances, but is not
strictly required.
+### targetpage
+
+ hook(type => "targetpage", id => "foo", call => \&targetpage);
+
+This hook can be used to override the name of the file a page should
+be compiled into.
+
+It should return the target filename.
+
+### tweakurlpath
+
+ hook(type => "tweakurlpath", id => "foo", call => \&tweakurlpath);
+
+This hook can be used to modify the internal urls generated by
+ikiwiki; it is run just after ikiwiki has removed the trailing
+`index.html`, in case `usedirs` is enabled.
+
+It should return the modified url.
+
+### tweakbestlink
+
+ hook(type => "tweakbestlink", id => "foo", call => \&tweakbestlink);
+
+This hook can be used to modify the page returned by `bestlink`. It is
+passed named parameters `page` and `link`. These are, respectively,
+the page where the link will appear and the link ikiwiki would choose
+as the best one, if no `tweakbestlink` hook was in effect.
+
+It should return the modified link.
+
## Plugin interface
To import the ikiwiki plugin interface:
Note that page state does not persist across wiki rebuilds, only across
wiki updates.
+### %wikistate
+
+The `%wikistate` hash can be used by a plugin to store persistant state
+that is not bound to any one page. To set a value, use
+`$wikistate{$id}{$key}=$value, where `$value` is anything Storable can
+serialize, `$key` is any string you like, and `$id` must be the same as the
+"id" parameter passed to `hook()` when registering the plugin, so that the
+state can be dropped if the plugin is no longer used.
+
### Other variables
If your plugin needs to access data about other pages in the wiki. It can
Passed a page name, returns the base name that will be used for a the html
page created from it. (Ie, it appends ".html".)
+Use this when constructing the filename of a html file. Use `urlto` when
+generating a link to a page.
+
#### `add_depends($$)`
Makes the specified page depend on the specified [[ikiwiki/PageSpec]].
Given the name of a source file, returns the name of the wiki page
that corresponds to that file.
+#### `pagetitle($)`
+
+Give the name of a wiki page, returns a version suitable to be displayed as
+the page's title. This is accomplished by de-escaping escaped characters in
+the page name. "_" is replaced with a space, and '__NN__' is replaced by
+the UTF character with code NN.
+
+#### `titlepage($)`
+
+This performs the inverse of `pagetitle`, ie, it converts a page title into
+a wiki page name.
+
+#### `linkpage($)`
+
+This converts text that could have been entered by the user as a
+[[WikiLink]] into a wiki page name.
+
#### `srcfile($;$)`
Given the name of a source file in the wiki, searches for the file in
If the third parameter is passed and is true, an absolute url will be
constructed instead of the default relative url.
+#### `newpagefile($$)`
+
+This can be called when creating a new page, to determine what filename
+to save the page to. It's passed a page name, and its type, and returns
+the name of the file to create, relative to the srcdir.
+
#### `targetpage($$)`
Passed a page and an extension, returns the filename that page will be
Adds the passed file to the archive. The filename is relative to the root
of the srcdir.

#### `rcs_rename($$)`
By the way, to parse a ikiwiki setup file and populate `%config`, a
program just needs to do something like:
`use IkiWiki::Setup; IkiWiki::Setup::load($filename)`
+
+### Javascript
+
+Some plugins use javascript to make ikiwiki look a bit more web-2.0-ish.
+
+All javascript code should be put in `.js` files in the `javascript`
+underlay, and plugins using those files can enable use of the underlay by
+calling `add_underlay("javascript");` in their `import` function.
+
+You'll have to arrange for `<script>` tags to be added to the pages that
+use your javascript. This can be done using a `format` hook.
+
+Ikiwiki provides some utility functions in `ikiwiki.js`, for use by other
+javascript code. These include:
+
+#### `getElementsByClass(cls, node, tag)`
+
+Returns an array of elements with the given class. The node and tag are
+optional and define what document node and element names to search.
+
+#### `hook(name, call)`
+
+The function `call` will be run as part of the hook named `name`.
+
+Note that to hook into `window.onload`, you can use the `onload' hook.
+
+#### `run_hooks(name)`
+
+Runs the hooks with the specified name.
