/*
 
== 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 the same 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
* Compatible 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)

Name:    wDiff.js
Version: 0.9.9 (October 10, 2010)
Info:    http://en.wikipedia.org/wiki/User:Cacycle/diff
Code:    http://en.wikipedia.org/wiki/User:Cacycle/diff.js
 
JavaScript diff algorithm by [[en:User:Cacycle]] (http://en.wikipedia.org/wiki/User_talk:Cacycle).
Outputs html/css-formatted new text with highlighted deletions, inserts, and block moves.
For newline highlighting the following style rules have to be added to the document:
	.wDiffParagraph:before { content: "¶"; };
 
The program uses cross-browser code and should work with all modern browsers. It has been tested with:
* Mozilla Firefox 1.5.0.1
* Mozilla SeaMonkey 1.0
* Opera 8.53
* Internet Explorer 6.0.2900.2180
* Internet Explorer 7.0.5730.11
This program is also compatible with Greasemonkey
 
An implementation of the word-based algorithm from:
 
Communications of the ACM 21(4):264 (1978)
http://doi.acm.org/10.1145/359460.359467
 
With the following additional feature:
 
* Word types have been optimized for MediaWiki source texts
* Additional post-pass 5 code for resolving islands caused by adding
	two common words at the end of sequences of common words
* Additional detection of block borders and color coding of moved blocks and their original position
* Optional "intelligent" omission of unchanged parts from the output
 
This code is used by the MediaWiki in-browser text editors [[en:User:Cacycle/editor]] and [[en:User:Cacycle/wikEd]]
and the enhanced diff view tool wikEdDiff [[en:User:Cacycle/wikEd]].
 
Usage: var htmlText = WDiffString(oldText, newText);
 
This code has been released into the public domain.
 
Datastructures (abbreviations from publication):
 
text: an object that holds all text related datastructures
	.newWords: consecutive words of the new text (N)
	.oldWords: consecutive words of the old text (O)
	.newToOld: array pointing to corresponding word number in old text (NA)
	.oldToNew: array pointing to corresponding word number in new text (OA)
	.message:  output message for testing purposes
 
symbol table:
	symbols[word]: associative array (object) of detected words for passes 1 - 3, points to symbol[i]
	symbol[i]: array of objects that hold word counters and pointers:
		.newCtr:  new word occurences counter (NC)
		.oldCtr:  old word occurences counter (OC)
		.toNew:   first word occurrence in new text, points to text.newWords[i]
		.toOld:   last word occurrence in old text, points to text.oldWords[i]
 
block: an object that holds block move information
	blocks indexed after new text:
	.newStart:  new text word number of start of this block
	.newLength: element number of this block including non-words
	.newWords:  true word number of this block
	.newNumber: corresponding block index in old text
	.newBlock:  moved-block-number of a block that has been moved here
	.newLeft:   moved-block-number of a block that has been moved from this border leftwards
	.newRight:  moved-block-number of a block that has been moved from this border rightwards
	.newLeftIndex:  index number of a block that has been moved from this border leftwards
	.newRightIndex: index number of a block that has been moved from this border rightwards
	blocks indexed after old text:
	.oldStart:  word number of start of this block
	.oldToNew:  corresponding new text word number of start
	.oldLength: element number of this block including non-words
	.oldWords:  true word number of this block
