The aggregate directive is supplied by the [[!iki plugins/aggregate desc=aggregate]] plugin. This plugin requires extra setup, specifically, a cron job. See the plugin's 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 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 inline directive to create a blog of one or more aggregated feeds. For example:

[[!inline  pages="internal(example/*)"]]

Note the use of internal() in the PageSpec to match aggregated pages. By default, aggregated pages are internal pages, which prevents them from showing up directly in the wiki, and so this special PageSpec is needed to match them.

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.
