The polyparse library on Hackage is another parser combinator framework that allows lazy incremental parsing. http://hackage.haskell.org/package/polyparse A PDF paper/tutorial is here: http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.118.1754&rep=rep1&type=pdf Regards, Malcolm _______________________________________________ Haskell-Cafe mailing list [email protected] http://www.haskell.org/mailman/listinfo/haskell-cafe
