[ragel-users] JavaScript code generation for Ragel

[Dominic Marks]

  Hi all,

I've got the table code generation strategy working. I'm going to work 
on building a set of RL files for testing purposes and then have a crack 
at writing a code generation backend that targets modern JavaScript VMs 
(e.g. produces JavaScript that best suits a JIT/tracer). If anyone would 
like to help with any part of this process, I'd be most grateful.

I've forked Ragel trunk into a github repo while I work on this. There 
is a sample script (I translated the maillbox.rl file from the Ragel 
distribution) which you can play with if you install Node.js (a 
JavaScript application framework powered by Google's V8 VM). Note that  
while the sample script uses Node.js for IO, but the code generated is 
plain JavaScript. I look forward to being able to use Ragel in the 
browser soon too.

A diff against Ragel trunk is here:

<http://goodforbusiness.co.uk/%7Edom/ragel-js-20101011.diff>

The code is mostly a cut-paste-and-replace from Ruby at the moment. I'll 
be tidying it up over the next few weeks, as my time allows. However, it 
does at least run one Ragel state machine correctly already.

Mailbox.rl/Mailbox.js:

Cheers,
Dom
