a whole filename that can be htmlized. This is useful for files
like `Makefile` that have no extension.
+If `hook` is passed an optional "longname" parameter, this value is used
+when prompting a user to choose a page type on the edit page form.

### pagetemplate
hook(type => "pagetemplate", id => "foo", call => \&pagetemplate);
since it's sometimes used to test to see which pages in a set of pages a
user can edit.
+### canremove
+
+ hook(type => "canremove", id => "foo", call => \&canremove);
+
+This hook can be used to implement arbitrary access methods to control
+when a page can be removed using the web interface (commits from
+revision control bypass it). It works exactly like the `canedit` hook,
+but is passed the named parameters `cgi` (a CGI object), `session`
+(a session object) and `page` (the page subject to deletion).
+
+### canrename
+
+ hook(type => "canrename", id => "foo", call => \&canrename);
+
+This hook can be used to implement arbitrary access methods to control when
+a page can be renamed using the web interface (commits from revision control
+bypass it). It works exactly like the `canedit` hook,
+but is passed the named parameters `cgi` (a CGI object), `session` (a
+session object), `src`, `srcfile`, `dest` and `destfile`.

### checkcontent
hook(type => "checkcontent", id => "foo", call => \&checkcontent);
additional parameters: `author`, `url`, and `subject`. The `subject`
parameter may also be filled with the user's comment about the change.
-Note: When the user edits an existing wiki page, the passed `content` will
-include only the lines that they added to the page, or modified.
+Note: When the user edits an existing wiki page, this hook is also
+passed a `diff` named parameter, which will include only the lines
+that they added to the page, or modified.
The hook should return `undef` on success. If the content is disallowed, it
should return a message stating what the problem is, or a function
hook(type => "renamepage", id => "foo", call => \&renamepage);
This hook is called by the [[plugins/rename]] plugin when it renames
-something. The hook is passed named parameters: `page`, `oldpage`,
-`newpage`, and `content`, and should try to modify the content to reflect
-the name change. For example, by converting links to point to the new page.

+
+### rename
+
+ hook(type => "rename", id => "foo", call => \&rename);
+
+When a page or set of pages is renamed, the referenced function is
+called for every page, and is passed named parameters:
+
+* `torename`: a reference to a hash with keys: `src`, `srcfile`,
+ `dest`, `destfile`, `required`.
+* `cgi`: a CGI object
+* `session`: a session object.
+
+Such a hook function returns any additional rename hashes it wants to
+add. This hook is applied recursively to returned additional rename
+hashes, so that it handles the case where two plugins use the hook:
+plugin A would see when plugin B adds a new file to be renamed.
### getsetup
and undef if a rebuild could be needed in some circumstances, but is not
strictly required.
+### genwrapper
+
+ hook(type => "genwrapper", id => "foo", call => \&genwrapper);
+
+This hook is used to inject C code (which it returns) into the `main`
+function of the ikiwiki wrapper when it is being generated.

## Plugin interface
To import the ikiwiki plugin interface:
Use this when constructing the filename of a html file. Use `urlto` when
generating a link to a page.
-#### `add_depends($$)`
+#### `add_depends($$;@)`
Makes the specified page depend on the specified [[ikiwiki/PageSpec]].
+By default, dependencies are full content dependencies, meaning that the
+page will be updated whenever anything matching the PageSpec is modified.
+This default can be overridden by additional named parameters, which can be
+used to indicate weaker types of dependencies:
+
+* `presence` if set to true, only the presence of a matching page triggers
+ the dependency.
+* `links` if set to true, any change to links on a matching page
+ triggers the dependency. This includes when a link is added, removed,
+ or changes what it points to due to other changes. It does not include
+ the addition or removal of a duplicate link.
+
#### `pagespec_match($$;@)`
-Passed a page name, and [[ikiwiki/PageSpec]], returns true if the
+Passed a page name, and [[ikiwiki/PageSpec]], returns a true value if the
[[ikiwiki/PageSpec]] matches the page.
+Note that the return value is overloaded. If stringified, it will be a
+message indicating why the PageSpec succeeded, or failed, to match the
+page.
+
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
Many plugins need to generate html links and add them to a page. This is
done by using the `htmllink` function. The usual way to call
-`htmlllink` is:
+`htmllink` is:
htmllink($page, $page, $link)
Passed a message, user, and ip address. Should commit all staged changes.
Returns undef on success, and an error message on failure.
