hook(type => "pagetemplate", id => "foo", call => \&pagetemplate);
-
[[Templates|wikitemplates]] are filled out for many different things in
ikiwiki, like generating a page, or part of a blog page, or an rss feed, or
a cgi. This hook allows modifying the variables available on those
the state is saved. The function can save other state, modify values before
they're saved, etc.
+### displaytime
+
+ hook(type => "displaytime", id => "foo", call => \&display);
+
+This hook can be registered to override the regular `displaytime` function.
+Only the last displaytime hook will be used.

### renamepage
hook(type => "renamepage", id => "foo", call => \&renamepage);
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.
