TWX / Or TW5+ -- Infinite Markup Options?

[@TiddlyTweeter]

I'm writing this here for lack of anywhere else. Its not up to Github standard so I can't post it there. But I think the issue is real and its more than the usual TW problem solving.

I have been using BJ's excellent "Flexity" Plugin for some weeks now. Its basically opened my eyes to ..

 (1) The central role of Parsing in TW.

 (2) The flex you can get when you can switch OFF some of the extant parsing rules and replace them with alternative markup.

 (3) The ease of using Regular Expressions (via BJ's method) to create totally new systems of markup very economically & efficiently without having to edit JavaScript.

WHAT is my point?

My point is that IF the current architecture of parsing could be opened up so that it were much easier to add "User Content Types" via markup mediated by a simple cascade of regular expressions (NOT via individual Javascript modules as is) for many use cases it could open the way for TW to become a near "Universal Markup Engine".

Over the next few weeks I hope to release a fully honed TW application for screenplays that uses the pure, standard, Fountain Markup system. But even without that yet complete I'm sensing that better, easier interface with the TW Parsers--and an easier way to add new parsing rules without recourse to JavaScript could be seriously healthy step for TW or TWX.

Best wishes
