# rawdog plugin to truncate article descriptions to N characters.
|

|
|
# Copyright 2006, 2013 Adam Sampson <ats@offog.org>
|
||
|
|
#
|
||
|
|
# To use this, give the feed you want to truncate a "truncate" argument:
|
||
|
|
# feed 30m http://offog.org/books/feed.rss
|
||
|
|
# truncate 40
|
||
|
|
#
|
||
|
|
# To truncate all articles, make that a default option for all feeds:
|
||
|
|
# feeddefaults
|
||
|
|
# truncate 40
|
||
|
|
#
|
||
|
|
# You can also remove all HTML tags from the descriptions before truncating
|
||
|
|
# them, which'll make the formatting a bit nicer if you're aiming for very
|
||
|
|
# short descriptions:
|
||
|
|
# killtags true
