Keep the parser/lexer for the source code in JJ> Haskell, but port only the interpreter to C? yes, you can use C and Haskell together. but C code can't walk Haskell data structures, so such co-working will need some manual work JJ> What would be a good place to start? I am reading Yet Another Haskell JJ> tutorial, and I've read the first 6 of two dozen lessons in Haskell. What to JJ> do next, practice/read more/start with the implementation of the scripting JJ> language? read about parsec library and start :) this lib already contains several examples of implementing small FP and imperative languages, each implemetation is just 5-10 kb in size -- Best regards, Bulat mailto:[EMAIL PROTECTED] _______________________________________________ Haskell mailing list Haskell@haskell.org http://www.haskell.org/mailman/listinfo/haskell
