19 """Magicaltastic front page.
21 Plugins can register a hook called 'frontpage_updates_<type>' to add
22 updates to the front page. `<type>` is an arbitrary string indicating
23 the sort of update the plugin knows how to handle; for example,
24 spline-forum has a `frontpage_updates_forum` hook for posting news from
27 Hook handlers should return a list of FrontPageUpdate objects.
29 Standard hook parameters are:
30 `limit`, the maximum number of items that should ever be returned.
31 `max_age`, the number of seconds after which items expire.
32 `title`, a name for the source.
33 `icon`, an icon to show next to its name.
35 `limit` and `max_age` are also global options.
37 Updates are configured in the .ini like so:
39 spline-frontpage.sources.foo = updatetype
40 spline-frontpage.sources.foo.opt1 = val1
41 spline-frontpage.sources.foo.opt2 = val2
43 Note that the 'foo' name is completely arbitrary and is only used for
44 grouping options together. This will result in a call to:
46 run_hooks('frontpage_updates_updatetype', opt1=val1, opt2=val2)
48 Local plugins can override the fairly simple index.mako template to
49 customize the front page layout.
