WMD is a small, simple WYSIWYM (What You See Is What You Mean) markdown editor written in Javascript. Type your text in markdown and WMD will convert it to HTML behind the scenes with an optional real-time preview.
This version of WMD has been tested with IE 6, 7 and 8 RC1, Firefox 3, Safari 3.2, Chrome 1.0 and Opera 9.6. iPhone and iPod Touch support is rumored to work with the exception of the link/image prompt location. There are a few (minor) known issues with keyboard handling in IE and Opera. See the issues page for more details.
This is a new Google Code project based on John Fraser's original WMD. Since John has disappeared off the Internet, I'll be hosting the new code here until he shows up.
Actual development takes place on github (see links). I'll create release versions and post them here when they are ready.
NOTE
Version 2.0 of this code was developed as a private bugfix/feature branch for Stackoverflow.com and is missing most of the optional features found in the original WMD as SO did not use them. Now that I'm putting this out on Google Code I'll be adding the new features back in v2.1 due out sometime in February 2009. Version 3.0 should be released in February/March 2009 and will a major rewrite making use of jQuery.
