[Haskell-cafe] Re: Propagating Parsec errors

Mark Carroll writes:

Is there a way in Parsec to, within a parser, throw an error generated by another parser?

How about wrapping the ParseError into your result type? Like this: data Foo = Bar String | ... | BadLuck ParseError Then you could run any number of parsers (with 'runParser') inside another parser and return their results and errors without needing any special support from the Parsec library.
