[[tag type/useful]]
This plugin allows content from other feeds to be aggregated into the wiki.
Aggregate a feed as follows
\[[aggregate name="example blog"
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, 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.
setup
Make sure that you have the [[html]] plugin enabled, as the created pages are
in html format. The [[meta]] and [[tag]] plugins are also recommended. The
[[htmltidy]] plugin is suggested, since feeds can easily contain html
problems, some of which tidy can fix.
You will need to run ikiwiki periodically from a cron job, passing it the
--aggregate parameter, to make it check for new posts. Here's an example
crontab entry:
*/15 * * * * ikiwiki --setup my.wiki --aggregate --refresh
Alternatively, you can allow ikiwiki.cgi to trigger the aggregation. You
should only need this if for some reason you cannot use cron, and instead
want to use a service such as WebCron. To enable
this, enable on aggregate_webtrigger in your setup file. The url to
visit is http://whatever/ikiwiki.cgi?do=aggregate_webtrigger. Anyone
can visit the url to trigger an aggregation run, but it will only check
each feed if its updateinterval has passed.
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.
Note that even if you are using subversion or another revision control
system, pages created by aggregation will not be checked into revision
control.
