I wrote a compiler in Clojure for a 4th year course. For parsing I used this combinator parser library: https://github.com/jasonjckn/clarsec which is modeled after haskell's parsec. However the performance was kind of bad, combinator parsers in general can be pretty slow.
In retrospect, I would have tried https://github.com/cgrand/parsley afaik it has ~LR1 performance characteristics. Beyond the above options, there's many LR1/LL1 parsers written in Java that are perfectly fine options. If you're parsing with a grammar file, you don't gain anything if the parser was written in Clojure versus Java. For lexing, I just used clojure's regular expression implementation. Not sure what libraries exist. -Jason On Friday, 18 May 2012 08:46:19 UTC-4, Alexsandro Soares wrote: > > Hi, > > I'm trying to build a compiler using Clojure.
