Re: Question about porting mzscheme code

Hi Dan,

Once I was also looking for a parser for sisc. I ended up using Dominique  
Boucher's LALR(1) parser generator that could be found here:
http://www.iro.umontreal.ca/~boucherd/Lalr/documentation/lalr.html#A-portable-and-efficient-LALR(1)-parser-generator-for-Scheme
http://code.google.com/p/lalr-scm/ (seems to be more recent)

As for the lexer I had to write it myself.

I hope it will help you.

Nikita
