A TiddlyWeb plugin that provides an Atom feed of tiddler collections.

Project description

The tiddlywebplugins.atom package provides serialization modules to
do a very simple Atom format syndication of collections of tiddlers
(including one tiddler, and filtered tiddlers).

One serialization provides support for the Atom format, another
extends the existing HTML serialization to provide <link> elements
referring to the Atom feeds.

Atom formatted output can be had by requesting the application/atom+xml
format, or by appending a .atom to the end of a URL (before the query
portion) that returns one or more tiddlers.

To use this code install the package and then add 'tiddlywebplugins.atom'
to system_plugins in the tiddlywebconfig.py of your instance:

config = {
'system_plugins': ['tiddlywebplugins.atom'],
}

If tiddlywebplugins.differ is on sys.path and a depth=<some number>
argument is supplied to the feed URL, then the resulting feed will be
the tiddlers requested presented as diffs between tiddler revisions. The
number of revisions shown is controlled by <some number>.

You can get tiddlywebplugins.differ from PyPI:
http://pypi.python.org/pypi/tiddlywebplugins.differ

By default the feed given is all the tiddlers in the collection represented
by the given URI, in no particular order. This is not always the best
default. If you want a different default you can set 'atom.default_filter'
in tiddlywebconfig.py to a string that represents a TiddlyWeb filter.
For example:

'atom.default_filter': 'select=tag:!excludeLists;sort=-modified;limit=20',

would give the 20 most recently modified tiddlers which are not tagged
'excludeLists'.

The Atom code is borrowed from Django's django/utils/feedgenerator.py
