+[[ikiwiki/directive/aggregate]] [[ikiwiki/directive]].
- \[[aggregate name="example blog" dir="example"
- feedurl="http://example.com/index.rss"
- url="http://example.com/" updateinterval="15"]]
+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.
-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. For example:
-
- \[[inline pages="internal(example/*)"]]

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.
-* `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.

-## internal pages
+## internal pages and `aggregateinternal`
This plugin creates a page for each aggregated item.
-Currently, by default, these pages have the ".html" extension, and are
-first-class wiki pages -- which allows them to be inlined into blogs
-and even edited.
+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/*)`.
-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 alternate method
-that can be used, turned on by the `aggregateinternal` option in the setup
-file.
+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.
-If `aggregateinternal` is enabled, 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.

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
+ 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. Use [[ikiwiki-transition]] to move all existing aggregated `.html`
- files. The command to run is `ikiwiki-transition aggregateinternal $srcdir`
-3. Turn on `aggregateinternal` in the setup file and rebuild the wiki.
