I've tried to retrieve the wmd-editor source tarball lately, but the site seems offline.
|
|
|
|
From what I've read on the Internet, wmd-editor is not (yet?) free software by itself, and its author has gone MIA.
|
|
But it looks like somebody recently took the step to rewrite a wmd-clone under a saner license, see [[pagedown|http://code.google.com/p/pagedown/source/browse/]].
|
|
|
|
Given all the above, what about upgrading this plugin to use pagedown instead of wmd? It seem a clear win to me...
|
|
|
|
> AFAICS, pagedown is a modified version of WMD. Let's

|
A javascript port of Markdown, as used on Stack Overflow
|
|
and the rest of Stack Exchange network.
|
|
|
|
Largely based on showdown.js by John Fraser (Attacklab).
