Does any one know of any parser generators for D? I'm linking against c files generated using bison, and while this works, It would be better if D had support for complex parsing tasks.

There's Enki:

http://www.dsource.org/projects/ddl/wiki/Enki

I've never used it, so I can't say how complete/powerful it is.

Antlr is supposed to have D support but I havn't even tried to use it. (I found antler to be hard to work with in general)
http://www.antlr.org/

there's also my project dparser. Not vary mature and not well tested but it doesn't requirer anything but DMD to build.

Besides the ones already mentioned, there's also this marvel of CTFE/template meta-programming that doesn't require any separate generation step (you put the BNF grammar right into your source file): http://www.dsource.org/projects/scrapple/browser/trunk/dparser

IMO, it's the coolest ting I've seen in D, but it'll bloat your compile-times to a few minutes if you use a complex grammar.

There is http://apaged.mainia.de for example.

do you have any documentation for it? If so I'll probably put it to use.

If you are planning on doing anything serious, be warned I have some major braking changes coming but I have no clue when. 

The current implementation forces the user to do gobs of down casts and I think I have figured out how to avoid that. However it is going to change the call signature on just about everything.

The documentation is at the top of the file. I have a revamp of that as well, but it's for the new version and again, pot luck on when it will get done.

This thing isn't alpha, it prototype, if that.

I'm a bit surprised that no-one has mentioned that the (kinda) new industry standard  hasn't been mentioned here..

Ragel:
http://research.cs.queensu.ca/~thurston/ragel/

it generates C, C++, Objective-C, ****D****, Java or Ruby code with no dependencies.

And a) generates very fast code, and b) is (frankly) very cool.

I just took a look at it. It loooks very promising. Thanks for the link.
