lexer-applicative's Issues

Semigroup instances

With a sufficiently new base the build fails due to missing Semigroup instances for Lexer and Recognizer.

Working with Text

Is it possible to build recognizers and runLexer that work on Text rather than the hardcoded Char and String?

Thank you for these projects.

Hangs

The following result hangs:

{-# LANGUAGE OverloadedStrings #-}

import Language.Lexer.Applicative (tokens)
import Text.Regex.Applicative
import qualified Data.Loc as Loc
import qualified Data.Char as Char

type Token = Integer

token :: RE Char Token
token = "one" *> pure 1

spaces :: RE Char ()
spaces = (many $ psym Char.isSpace) *> pure ()

result :: [Loc.L Token]
result = tokens token spaces "filename" "one -"
