type SimpleStringParser a = Parsec CustomErr String a

A parser of string to some type.

type SimpleTextParser = Parsec CustomErr Text

A parser of strict text to some type.

type TextParser m a = ParsecT CustomErr Text m a

A parser of text in some monad.

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

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

type ErroringJournalParser m a = StateT Journal (ParsecT CustomErr Text (ExceptT FinalParseError m)) a

A parser of text in some monad, with a journal as state, that can throw a "final" parse error that does not backtrack.

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

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

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

parseWithState :: Monad m => st -> StateT st (ParsecT CustomErr Text m) a -> Text -> m (Either (ParseErrorBundle Text CustomErr) a)

Run a stateful parser with some initial state on a text. See also: runTextParser, runJournalParser.

re-exports

data CustomErr

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