Alice browses to a page and clicks Edit.
-* Ikiwiki is run as a cgi. It assigns Alice a session cookie, and,
- by calling the `auth` hooks, sees that she is not yet logged in.
-* The `sessioncgi` hooks are then called, and one of them,
- from the [[editpage]] plugin, notices that the cgi has been told "do=edit".
-* The [[editpage]] plugin calls the `canedit` hook to check if this
- page edit is allowed. The [[signinedit]] plugin has a hook that says not:
- Alice is not signed in.

Alice signs in with her openid.

## Types of plugins
The function is passed named parameters "page" and "content". Its return
value is ignored.
+### <a name="readtemplate">readtemplate</a>
+
+ hook(type => "readtemplate", id => "foo", call => \&readtemplate);
+
+Runs on the raw source of a page or `*.tmpl` file that is being
+used as a template, before it is parsed by [[!cpan HTML::Template]].
+For instance, the [[plugins/templatebody]] plugin uses this to return
+the content of the [[ikiwiki/directive/templatebody]] directive (if there
+is one) instead of the page's full content.
+
+The function is passed named parameters:
+
+* `id`: the name under which the template was looked up,
+ such as `page.tmpl` or `note`
+* `page`: the name of the template as a page or attachment in the wiki,
+ such as `templates/note`, or `undef` if it's outside the wiki (e.g. in
+ `/usr/share/ikiwiki/templates`)
+* `content`: the content of the corresponding file
+* `untrusted`: true if the template was loaded from the wiki or an underlay,
+ false if it was loaded from a trusted location
+
+It should return the replacement content.
+
### <a name="filter">filter</a>
hook(type => "filter", id => "foo", call => \&filter);
Note that cgi hooks are called as early as possible, before any ikiwiki
state is loaded, and with no session information.
-### auth
+### <a name="auth">auth</a>
hook(type => "auth", id => "foo", call => \&auth);
if the name is set to the name of a user who is not registered,
a basic registration of the user will be automatically performed.
-### sessioncgi
+### <a name="sessioncgi">sessioncgi</a>
hook(type => "sessioncgi", id => "foo", call => \&sessioncgi);
object and a session object. To check if the user is in fact signed in, you
can check if the session object has a "name" parameter set.
-### canedit
+### <a name="canedit">canedit</a>
hook(type => "canedit", id => "foo", call => \&canedit);
but is passed the named parameters `cgi` (a CGI object), `session` (a
session object), `src`, `srcfile`, `dest` and `destfile`.
-### checkcontent
+### <a name="checkcontent">checkcontent</a>
hook(type => "checkcontent", id => "foo", call => \&checkcontent);
that can be run to perform whatever action is necessary to allow the user
to post the content.
-### editcontent
+### <a name="editcontent">editcontent</a>
hook(type => "editcontent", id => "foo", call => \&editcontent);
It can modify the content as desired, and should return the content.
-### formbuilder

hook(type => "formbuilder_setup", id => "foo", call => \&formbuilder_setup);
hook(type => "formbuilder", id => "foo", call => \&formbuilder);

* `section` can optionally specify which section in the config file
the plugin fits in. The convention is to name the sections the

### genwrapper
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 `$value` is anything Storable can
+`$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.
of a page. So the key is the page name, and the value is the source
filename. Do not modify this hash.
+Attachments also appear in this hash, with the same key and value.
+
$pagesources{"foo"} = "foo.mdwn";
+ $pagesources{"logo/ikiwiki.png"} = "logo/ikiwiki.png";

### `%destsources`
The `%destsources` hash records the name of the source file used to
create each destination file. The key is the output filename (ie,
-"foo/index.html"), and the value is the source filename that it was built
-from (eg, "foo.mdwn"). Note that a single source file may create multiple
+"foo/index.html"), and the value is the name of the page that it was built
+from (eg, "foo"). Note that a single source file may create multiple
destination files. Do not modify this hash directly; call `will_render()`.
-
- $destsources{"foo/index.html"} = "foo.mdwn";

+Attachments also appear in this hash, with the same key and value.
+
+ $destsources{"foo/index.html"} = "foo";
+ $destsources{"logo/ikiwiki.png"} = "logo/ikiwiki.png";
## Library functions
This hook and `rcs_preprevert` are optional, if not implemented, no revert
web interface will be available.
+### `rcs_find_changes($)`
+
+Finds changes committed since the passed RCS-specific rev. Returns
+a hash of the files changed, a hash of the files deleted, and the
+current rev.
+
+This hook is optional.
+
+### `rcs_get_current_rev()`
+
+Gets a RCS-specific rev, which can later be passed to `rcs_find_changes`.
+
+This hook is optional.

### PageSpec plugins
It's also possible to write plugins that add new functions to
