This is a copy of InstaView for use in other applications like [[User:Cacycle/wikEd|wikEd]].

* InstaView - a Mediawiki to HTML converter in JavaScript
|
||||||
|
* Version 0.6.1
|
||||||
|
* Copyright (C) Pedro Fayolle 2005-2006
|
||||||
|
* http://en.wikipedia.org/wiki/User:Pilaf
|
||||||
|
* Distributed under the BSD license
|
||||||
|
*
|
||||||
|
* Changelog:
|
||||||
|
*
|
||||||
|
* 0.6.1
|
||||||
|
* - Fixed problem caused by \r characters
|
||||||
|
* - Improved inline formatting parser
|
||||||
|
*
|
||||||
|
* 0.6
|
||||||
|
* - Changed name to InstaView
|
||||||
|
* - Some major code reorganizations and factored out some common functions
|
||||||
|
* - Handled conversion of relative links (i.e. [[/foo]])
|
||||||
|
* - Fixed misrendering of adjacent definition list items
|
||||||
|
* - Fixed bug in table headings handling
|
||||||
|
* - Changed date format in signatures to reflect Mediawiki's
|
||||||
|
* - Fixed handling of [[:Image:...]]
|
||||||
|
* - Updated MD5 function (hopefully it will work with UTF-8)
|
||||||
|

|
||||||
|
*
|

|
||||||
|
* - Better support for <math>
|
||||||
|
* - Full support for <nowiki>
|
||||||
|
* - Parser-based (as opposed to RegExp-based) inline wikicode handling (make it one-pass and bullet-proof)
|
||||||
|
* - Support for templates (through AJAX)
|
||||||
|
* - Support for coloured links (AJAX)
