## Registering plugins
All plugins should `use IkiWiki` to import the ikiwiki plugin interface.
+It's a good idea to include the version number of the plugin interface that
+your plugin expects: `use IkiWiki 2.00`
Plugins should, when imported, call `hook()` to hook into ikiwiki's
processing. The function uses named parameters, and use varies depending on
This is identical to a preprocess hook (see below), except that it is
called in the initial pass that scans pages for data that will be used in
-later passes. Scan hooks are the only hook that should modify
+later passes. Scan hooks are the only hook that should modify `%links`.

parameters: `cgi`, `session`, and `form`. These are, respectively, the
`CGI` object, the user's `CGI::Session`, and a `CGI::FormBuilder`.
-Each time a form is set up, the formbuilder_setup hook is called.
-Typically the formbuilder_setup hook will check the form's title, and if
+Each time a form is set up, the `formbuilder_setup` hook is called.
+Typically the `formbuilder_setup` hook will check the form's title, and if
it's a form that it needs to modify, will call various methods to
add/remove/change fields, tweak the validation code for the fields, etc. It
will not validate or display the form.
If your plugin needs to access data about other pages in the wiki. It can
use the following hashes, using a page name as the key:
-* `%links` lists the names of each page that a page links to, in an array
+* `links` lists the names of each page that a page links to, in an array
reference.
-* `%renderedfiles` lists names of the files rendered by a page, in an array
- reference.
-* `%pagesources` contains the name of the source file for a page.
+* `%destsources` contains the name of the source file used to create each
+ destination file.
+* `%pagesources` contains the name of the source file for each page.
Also, the %IkiWiki::version variable contains the version number for the
ikiwiki program.
Makes the specified page depend on the specified [[PageSpec]].

+Passed a page name, and [[PageSpec]], returns true if the [[PageSpec]]
+matches the page.
-Passed a page name, a [[PageSpec]], and the location the [[PageSpec]] should
-be matched against, returns true if the [[PageSpec]] matches the page. (If
-the third parameter is not passed, relative PageSpecs will match relative to
-the top of the wiki.)
+Additional named parameters can be passed, to further limit the match.
+The most often used is "location", which specifies the location the
+PageSpec should match against. If not passed, relative PageSpecs will match
+relative to the top of the wiki.
#### `bestlink($$)`
[[PageSpecs|PageSpec]]. Such a plugin should add a function to the
IkiWiki::PageSpec package, that is named `match_foo`, where "foo()" is
how it will be accessed in a [[PageSpec]]. The function will be passed
-three parameters: The name of the page being matched, the thing to match
-against, and the page that the matching is occuring on. It should return
-true if the page matches.
+two parameters: The name of the page being matched, and the thing to match
+against. It may also be passed additional, named parameters. It should return
+a IkiWiki::SuccessReason object if the match succeeds, or an
+IkiWiki::FailReason object if the match fails.
