# RSS to MetaWeblog bridge
# Copyright (C) 2002 Phillip Pearson

# A little script to poll an RSS feed and post all the new items to a
# weblog using the MetaWeblog API.

# Built for the group-forming mailing list, so you'll want to change
# some of the language below if you have a different application.

# To use, save your login name in rpcLogin.txt ('echo foobar >
# rpcLogin.txt') and your password in rpcPassword.txt ('echo password
# > rpcPassword.txt').  Then change the URLs below.

# You'll also need a copy of Mark Pilgrim's RSS parser.  You can fetch
# it from:

#        http://diveintomark.org/projects/misc/rssparser.py.txt

# (Rename that to rssparser.py).

# Note that you need to have a blog already set up.  I used Movable
# Type, with comments etc turned off.  Blogger unfortunately won't do
# as it doesn't support posting titles.  Radio UserLand should work
# fine, although you need a Windows box and will have to leave Radio
# running all the time.

# the RSS feed:
rssUrl = 'http://www.aquameta.com/gf/list.rss'
# the weblog data:
blogUrl = 'http://dev.myelin.co.nz/gf/'
rpcUrl = 'http://dev.myelin.co.nz/gf/mt-xmlrpc.cgi'
rpcLogin = open( 'rpcLogin.txt' ).readline().rstrip()
rpcPassword = open( 'rpcPassword.txt' ).readline().rstrip()
# file for caching recent posts
cacheFn = 'cache.dat'

# Thanks to Mark Pilgrim for the RSS parser, and the Python team for a
# very nice language.
