Data.Conduit.Attoparsec

Description

Consume attoparsec parsers via conduit.

This code was taken from attoparsec-enumerator and adapted for conduits.

Synopsis

Sink

sinkParser :: (AttoparsecInput a, MonadThrow m) => Parser a b -> ConduitT a o m b Source #

Convert an Attoparsec Parser into a Sink. The parser will be streamed bytes until it returns Done or Fail.

If parsing fails, a ParseError will be thrown with throwM.

Since 0.5.0

sinkParserEither :: (AttoparsecInput a, Monad m) => Parser a b -> ConduitT a o m (Either ParseError b) Source #

Same as sinkParser, but we return an Either type instead of raising an exception.

Since 1.1.5

Conduit

conduitParser :: (AttoparsecInput a, MonadThrow m) => Parser a b -> ConduitT a (PositionRange, b) m () Source #

Consume a stream of parsed tokens, returning both the token and the position it appears at. This function will raise a ParseError on bad input.

Since 0.5.0

conduitParserEither :: (Monad m, AttoparsecInput a) => Parser a b -> ConduitT a (Either ParseError (PositionRange, b)) m () Source #

Same as conduitParser, but we return an Either type instead of raising an exception.
