Documentation

type SimpleStringParser a = Parsec CustomErr String a Source #

A parser of string to some type.

type SimpleTextParser = Parsec CustomErr Text Source #

A parser of strict text to some type.

type TextParser m a = ParsecT CustomErr Text m a Source #

A parser of text in some monad.

type JournalParser m a = StateT Journal (ParsecT CustomErr Text m) a Source #

A parser of text in some monad, with a journal as state.

choice' :: [TextParser m a] -> TextParser m a Source #

Backtracking choice, use this when alternatives share a prefix. Consumes no input if all choices fail.

choiceInState :: [StateT s (ParsecT CustomErr Text m) a] -> StateT s (ParsecT CustomErr Text m) a Source #

Backtracking choice, use this when alternatives share a prefix. Consumes no input if all choices fail.

surroundedBy :: Applicative m => m openclose -> m a -> m a Source #

parsewith :: Parsec e Text a -> Text -> Either (ParseError Char e) a Source #

parsewithString :: Parsec e String a -> String -> Either (ParseError Char e) a Source #

parseWithState :: Monad m => st -> StateT st (ParsecT CustomErr Text m) a -> Text -> m (Either (ParseError Char CustomErr) a) Source #

parseWithState' :: Stream s => st -> StateT st (ParsecT e s Identity) a -> s -> Either (ParseError (Token s) e) a Source #

fromparse :: (Show t, Show e) => Either (ParseError t e) a -> a Source #

parseerror :: (Show t, Show e) => ParseError t e -> a Source #

showDateParseError :: (Show t, Show e) => ParseError t e -> String Source #

nonspace :: TextParser m Char Source #

isNonNewlineSpace :: Char -> Bool Source #

spacenonewline :: (Stream s, Char ~ Token s) => ParsecT CustomErr s m Char Source #

restofline :: TextParser m String Source #

eolof :: TextParser m () Source #

re-exports

data CustomErr Source #

A custom error type for the parser. The type is specialized to parsers of Text streams.
