This plugin allows content from other feeds to be aggregated into the wiki.
Aggregate a feed as follows:
- \[[aggregate name="example blog" dir="example"
+ \[[!aggregate name="example blog" dir="example"
feedurl="http://example.com/index.rss"
url="http://example.com/" updateinterval="15"]]
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/*)"]]
+ \[[!inline pages="internal(example/*)"]]
## 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
+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.
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`
+2. Use [[ikiwiki-transition]] to rename all existing aggregated `.html`
+ files in the input directory, and delete the corresponding files from
+ the output directory. The command to run is
+ `ikiwiki-transition aggregateinternal $setupfile`
3. Turn on `aggregateinternal` in the setup file and rebuild the wiki.
