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...

-> Ok, so it says it's based on showdown. John Fraser wrote showdown and also
-> WMD, which IIRC was built on top of showdown. (Showdown converts the
-> markdown to html, and WMD adds the editor UI.)
->
-> I can nowhere find a actual statement of the copyright of showdown or
-> WMD. <http://code.google.com/p/wmd/> has a "MIT License" notice on it,
-> but this is clearly just the license chosen when signing up at google
-> code for the repo that would be used for a rewrite of the code, and the only thing
-> said about the previous 1.0 release of WMD is "use it freely", which is not
-> specific enough to be a grant of license, and is moreover not a free
-> software license, as it does not cover distribution or modification.
->
-> Which was all covered in the thread here,
-> when StackOverflow decided to start working on pagedown.
-> <http://blog.stackoverflow.com/2008/12/reverse-engineering-the-wmd-editor/>
-> This thread does not give any indication that they ever managed to get
-> a license grant for WMD/showdown. It frankly, does not inspire confidence
-> that the people working on this care about the license.
->
-> It would probably be pretty easy to adapt the ikiwiki wmd plugin
-> to use pagedown. But without a clear and credible license, why?
->
-> (Note that I have a wmd-new branch in my ikiwiki git repo that
-> uses <https://github.com/derobins/wmd>, which was an earlier
-> version of pagedown (probably, not entirely clear).)
->
-> An alternate alternative is markitup: <http://markitup.jaysalvat.com/>
-> It has a clear history and a credible license (MIT or GPL dual license).
-> It's also easily extensible to other formats so could handle rst etc.
-> It does not, however, have a markdown to html converter -- for
-> previewing it has to talk to the server with AJAX.

+<https://code.google.com/archive/p/pagedown/> is 404, <https://github.com/edrohler/pagedown-core> claims to be its copy but it does not have 'wmd' directory inside. What are the current steps to follow here? --[[svetlana]]
