Data.Conduit.Attoparsec
Description
Consume attoparsec parsers via conduit.
This code was taken from attoparsec-enumerator and adapted for conduits.
Synopsis
- sinkParser :: (AttoparsecInput a, MonadThrow m) => Parser a b -> ConduitT a o m b
- sinkParserEither :: (AttoparsecInput a, Monad m) => Parser a b -> ConduitT a o m (Either ParseError b)
- conduitParser :: (AttoparsecInput a, MonadThrow m) => Parser a b -> ConduitT a (PositionRange, b) m ()
- conduitParserEither :: (Monad m, AttoparsecInput a) => Parser a b -> ConduitT a (Either ParseError (PositionRange, b)) m ()
- data ParseError
- = ParseError { }
- | DivergentParser
- data Position = Position {}
- data PositionRange = PositionRange {
- posRangeStart :: !Position
- posRangeEnd :: !Position
- class AttoparsecInput a
Sink
sinkParser :: (AttoparsecInput a, MonadThrow m) => Parser a b -> ConduitT a o m b Source #
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.
