Hi Kashyap They are very close - Parsec has most of the parsers in ParseLib in either the Parsec.Char or Parsec.Combinator modules, if you import the Parsec top level, you will get them, e.g:
import Text.ParserCombinators.Parsec
ParseLib has - ident, nat, int - which have analogues in Parsec but are in the Parsec.Token module and need the qualified import trick:
import Text.ParserCombinators.Parsec.Language import qualified Text.ParserCombinators.Parsec.Token as P
myLex :: P.TokenParser st myLex = P.makeTokenParser emptyDef
integer :: Parser Integer integer = P.integer myLex
ident :: Parser String ident = P.identifier myLex
Handling trailing white-space is probably another difference that I haven't looked at yet (the variations - identifier, integer, natural - in ParseLib). Type signatures are slightly different, of course, as Parsec has more powerful "internal machinery". Best wishes Stephen
