|
|
|
This plugin allows content from other feeds to be aggregated into the
|
|
wiki. To specify feeds to aggregate, use the
|
|
[[ikiwiki/directive/aggregate]] [[ikiwiki/directive]].
|
|
|
|
New users of aggregate should enable the `aggregateinternal => 1` option in the
|
|
.setup file. If you don't do so, you will need to enable the [[html]] plugin
|
|
as well as aggregate itself, since feed entries will be stored as HTML.
|
|
|
|
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](http://webcron.org). To enable
|
|
this, turn 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.
|
|
|
|
## internal pages and `aggregateinternal`
|
|
|
|
This plugin creates a page for each aggregated item.
|
|
|
|
If the `aggregateinternal` option is enabled in the setup file (which is
|
|
recommended), aggregated pages are stored in the source directory with a
|
|
"._aggregated" extension. These pages cannot be edited by web users, and
|
|
do not generate first-class wiki pages. They can still be inlined into a
|
|
blog, but you have to use `internal` in [[PageSpecs|IkiWiki/PageSpec]],
|
|
like `internal(blog/*)`.
|
|
|
|
For backward compatibility, the default is that these pages have the
|
|
".html" extension, and are first-class wiki pages -- each one generates
|
|
a separate HTML page in the output, and they can even be edited.
|
|
|
|
That turns out to not be ideal for aggregated content, because publishing
|
|
files for each of those pages is a waste of disk space and CPU, and you
|
|
probably don't want to allow them to be edited. So, there is an alternative
|
|
method that can be used (and is recommended), turned on by the
|
|
`aggregateinternal` option in the setup file.
|
|
|
|
If you are already using aggregate and want to enable `aggregateinternal`,
|
|
you should follow this process:
|
|
|
|
1. Update all [[PageSpecs|ikiwiki/PageSpec]] that refer to the aggregated
|
|
pages -- such as those in inlines. Put "internal()" around globs
|
|
in those PageSpecs. For example, if the PageSpec was `foo/*`, it should
|
|
be changed to `internal(foo/*)`. This has to be done because internal
|
|
pages are not matched by regular globs.
|
|
2. Turn on `aggregateinternal` in the setup file.
|
|
3. Use [[ikiwiki-transition]] to rename all existing aggregated `.html`
|
|
files in the srcdir. The command to run is
|
|
`ikiwiki-transition aggregateinternal $setupfile`,
|
|
4. Refresh the wiki. (`ikiwiki -setup your.setup -refresh`)
