Defined in:
lib/abqari/feed.rb

Overview

Generates RSS + JSON Feed for a single collection. Per-collection feeds are opt-in via collections.<name>.feeds.enabled (default true for posts — back-compat — and false for everything else).

Output paths:

posts        →  /feed.xml + /feed.json   (back-compat root paths)
<other>      →  /<collection>/feed.xml + /<collection>/feed.json

The root /feed.xml for posts is intentional: pre-existing subscribers + feed-reader caches keep working without redirects.

def initialize(site, collection_name = 'posts')
  @site = site
  @collection_name = collection_name
end

Class Method Details

.write_all(site) ⇒ Object

Class-level entry point: writes feeds for every collection that has feeds.enabled: true. Defaults to true only for posts so existing sites don't suddenly start emitting photo / publication feeds without opt-in.
