== wikEdDiff ==
 
A user script that provides an improved and easier to read diff view for comparing article versions
on Wikipedia and other MediaWiki sites.
 
Features:
* Additions and deletions are highlighted by color in a single article text
* Block moves are detected and indicated by color
* Unchanged regions of the text are omitted from the output
* Highly optimized for MediaWiki source texts
* Compatibel with Greasemonkey
 
wikEdDiff uses the Cacycle diff.js routines [[en:User:Cacycle/diff]] and is also an integrated part of wikEd,
the full-featured JavaScript in-browser editor (http://en.wikipedia.org/wiki/User:Cacycle/wikEd)
