# Feedwise Plugin version 0.2 for Rawdog. # Copyright 2005 Ian Glover # Copyright 2006 Virgil Bucoci # # Sort articles into chunks by feed rather than date. # # Wed Sep 6 16:32:40 EEST 2006 # Modified by Virgil Bucoci # * use the right hook to write the feed headings # * sort feeds by feed name # * added navigation links between feeds # * feed content gets wrapped in ordered-list tags, so if you add # list-item tags

to your item template, you will get per-feed # numbered articles # * added default value for articles_per_feed config option (idea # stolen from Dog Walker , # http://lists.us-lot.org/pipermail/rawdog-users/2006-September/000254.html) # * minor code cleanup import rawdoglib.plugins class FeedwisePlugin: def __init__(self): self.last_feed = None self.feed_no = 0 def startup(self, rawdog, config): # daysections and timesections config options are not used # when this plugin is used.
