Hey all,
I'm currently working on the new Capiunto MediaWiki extension[1], which adds infobox functionality to Scribunto (and the MediaWiki parser in general).
The Capiunto extension uses the HtmlBuilder Lua module[2] originally from enwiki to create the Infobox html. The HtmlBuilder provides general support for creating html in an easy and flexible way (maybe comparable to jQuery in JavaScript). Because of this and because it doesn't really fit into Capiunto we consider adding it directly to Scribunto. That way one could access its functionality directly as (maybe) mw.html.
Prior to adding it to Scribunto I will review, document and write unit tests for the module.
I hope you agree that this module is nice to have and that it fits into Scribunto best.
Cheers,
Marius
