I looked at ragel and I will probably end up using it. Does anyone know where I can find examples or further documentation for using it with d.

That is very cool. Deserves a link on the D website, I reckon. The number of quality tools with native support for D is quite limited, and we should promote them as much as possible.

I'm working on one right now as a side project, but it's nowhere near being in any usable form yet.

GOLD (http://www.devincook.com/goldparser/) is a forever free tool for visual aiding the definition of LALR(1)-grammars for a given language.

It has an import feature for yacc grammars and can generate parsers and scanners in D. The generation process is guided by user definable macros.

A macro collection for D is available (author: Matthias Piepkorn) http://www.devincook.com/goldparser/engine/d/index.htm

I have setup a macro collection too, which seems to be twice as fast as Matthias'. My collection is unpublished but I am willing to share on a personal basis.
