I'm more interested in doing this using Lisp than anything else. I'm just trying to figure out which Lisp suits my needs the best. Is there one that is particularly suited for this task, or is it just a matter of preference?
In particular, you've said so little about what what exactly you want to parse, what parsers you've tried, and how they haven't suited your needs that I have no way of making further suggestions.
I'm just asking in general for the most part. I have very little planned at the moment.
I've done a little bit of work with parsing, but I'm somewhat new to lisp. And it's a bit difficult to choose between scheme, clojure, common lisp, and arc. The thing that I'll most likely spend most of my time doing with it is parsing and writing toy interpreters, so focusing on the parsing libraries available seemed like a good approach.
