The Tagger extension allows organizing site content based upon tags meta-data in paginated collections.


Given the configuration of:

  extension :posts, 
                                               :per_page=>10 )

The extension will scan site.posts for every item with a tags attribute. For each observed tag, a structure is created with the following behaviour

These structures will be sorted by popularity, trimmed to the top 100 tags, and placed into site.posts_tags as an ordered array. This array

Method Description
to_s The seen tag
primary_page First page in this tag's index collection
pages All pages with the tag
group Which group is this tag in terms of popularity

From this analysis, the extension will create a paginated index for each of the top 100 tags. The input_path page denotes which page should be used to iterate the tag's page collection.

The page.posts collection, in this case, will hold the page's worth of posts with a given tag.

The indexes will be output under the output_prefix directory.

The pages listing all posts of 1 specific tag (so filtering out other posts), have a page.selected_tag variable with the name of the tag, which is usefull to adjust the page title accordingly.

To draw a full tag-cloud, the TagCloud extension should be used.
