parser generators for schemeThis is a discussion on parser generators for scheme within the Scheme forums in Programming Languages category; Hi, I currently working on a compiler/interpreter type system in scheme and I was if there are any good parser generation tools for scheme which include the ability to track the character position of tokens in the parse stream for both error reporting during semantic analysis and runtime. The only tool I have found so far is lalr-scm where I am not sure if you can use it as is to handle the case where the token returned by the lexer is a list including the extra data. Thanks in advance, Carter.... | ||||||||

Essence does all of this: http://www.informatik.uni-freiburg.d...tware/essence/ A greatly reworked version is almost finished (as well as a scanner generator to go with it). If you're interested in using it, please let me know, and I'll get you access to the code. -- Cheers =8-} Mike Friede, Völkerverständigung und überhaupt blabla |

Will it run on R6RS? Cheers leppie |

The parser generator is Scheme-48-specific, mostly because PGG is, which it builds upon. However, the generated parsers are very vanilla R5RS code, that would be trivially to embed in an R6RS module. I've put actually generating a R6RS module on the TODO list for the release. -- Cheers =8-} Mike Friede, Völkerverständigung und überhaupt blabla |
