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 -> Consumer a m bSource

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 monadThrow.

Since 0.5.0

Conduit

conduitParser :: (AttoparsecInput a, MonadThrow m) => Parser a b -> Conduit a m (PositionRange, b)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 -> Conduit a m (Either ParseError (PositionRange, b))Source

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

Types

data ParseError Source

The context and message from a Fail value.

data Position Source

Classes
