type TextParser m a = ParsecT Dec Text m a

A parser of strict text with generic user state, monad and return type.

type JournalStateParser m a = StateT Journal (ParsecT Dec Text m) a

type JournalParser a = StateT Journal (ParsecT Dec Text Identity) a

type ErroringJournalParser a = StateT Journal (ParsecT Dec Text (ExceptT String IO)) a

A journal parser that runs in IO and can throw an error mid-parse.

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 Dec Text m) a] -> StateT s (ParsecT Dec Text m) a

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