Any usable parsers for D2 around?

The Poseidon author added some D2 support for it in his editor, so I have kept an eye on that. But interfacing with D1 code from D2 is kind of complicated, and I need to use it from D2. (I guess I could get away with writing a DLL with a simple interface for D2 or something..).

Specifically I need these tools for use with an editor/IDE, which is something I'm working on for fun atm. But working on a parser is probably a ton of work, + the whole thing screams NIH to me. Luckily enough I don't have to reinvent a GUI and an editing control, there's DFL and Scintilla which are pretty awesome for my needs.

If you just need a d2 parser library, then my port of boost::spirit 
might fill you need:

http://www.sstk.co.uk/spiritd.php

(I pretty sure the bug that stopped it working got fixed in the last 
release, but I've not tested it yet.)

Though spirit generates LL parsers which aren't really suited for 
parsing human generated input; as getting accurate error location 
reporting is tricky, but it's handy for small inline parsers and other 
simple grammars.

If you are after a d2 parser written in d2, then I dunno.
You could write that using spirit in theory but it would be a job and a 
half.
