As for D lexers and tokenizers, what would be nice is to
A) build an antlr grammar for D
B) build D targets for antlr so that antlr can generate lexers and
parsers in the D language.
For B) I found http://www.mbutscher.de/antlrd/index.html
For A) A good list of antlr grammars is at
http://www.antlr.org/grammar/list, but there isn't a D grammar.
These things wouldn't be an enormous amount of work to create and
maintain, and, if done, anyone could parse D code in many languages,
including Java and C which would make providing IDE features for D
development easier in those languages (eclipse for instance),
and you
could build lexers and parsers in D using antlr grammars.

Yes, that would be much better. It would be directly and immediately
useful for the DDT project:
"But better yet would be to start coding our own custom parser
(using a parser generator like ANTLR for example), that could really
be tailored for IDE needs. In the medium/long term, that's probably
what needs to be done. "

I don't know about Ellery, as you can see in that thread he/she(?)
mentioned interest in working on that, but I don't know anything more.
As for me, I didn't work on that, nor did I plan to.
Nor am I planning to anytime soon, DDT can handle things with the
current parser for now (bugs can be fixed on the current code, perhaps
some limitations can be resolved by merging some more code from DMD), so
I'll likely work on other more important features before I go there. For
example, I'll likely work on debugger integration, and code completion
improvements before I would go on writing a new parser from scratch.
Plus, it gives more time to hopefully someone else work on it. :P
Unlike Walter, I can't write a D parser in a weekend... :) Not even on a
week, especially since I never done anything of this kind before.
