The `aggregate` directive is supplied by the [[!iki plugins/aggregate]] plugin.
2008-09-11 23:18:42 +02:00
This plugin requires extra setup, specifically, a cron job.
See the plugin documentation for details.
This directive allows content from other feeds to be aggregated into the wiki.
Aggregate a feed as follows:
\[[!aggregate name="example blog" dir="example"
feedurl="http://example.com/index.rss"
url="http://example.com/" updateinterval="15"]]
That example aggregates posts from the specified RSS feed, updating no
2008-09-11 23:14:21 +02:00
more frequently than once every 15 minutes (though possibly less
frequently, if the cron job runs less frequently than that), and puts a
page per post under the example/ directory in the wiki.
You can then use ikiwiki's [[ikiwiki/blog]] support to create a blog of one or
more aggregated feeds. For example:
\[[!inline pages="internal(example/*)"]]
## usage
Here are descriptions of all the supported parameters to the `aggregate`
directive:
* `name` - A name for the feed. Each feed must have a unique name.
Required.
* `url` - The url to the web page for the feed that's being aggregated.
Required.
* `dir` - The directory in the wiki where pages should be saved. Optional,
if not specified, the directory is based on the name of the feed.
* `feedurl` - The url to the feed. Optional, if it's not specified ikiwiki
will look for feeds on the `url`. RSS and atom feeds are supported.
* `updateinterval` - How often to check for new posts, in minutes. Default
is 15 minutes.
* `expireage` - Expire old items from this feed if they are older than
a specified number of days. Default is to never expire on age.
* `expirecount` - Expire old items from this feed if there are more than
the specified number total. Oldest items will be expired first. Default
is to never expire on count.
* `tag` - A tag to tag each post from the feed with. A good tag to use is
the name of the feed. Can be repeated multiple times. The [[tag]] plugin
must be enabled for this to work.
* `template` - Template to use for creating the aggregated pages. Defaults to
aggregatepost.
Note that even if you are using subversion or another revision control
system, pages created by aggregation will *not* be checked into revision
control.
