Changes

Changelog

2.1

  • Restore compatibility with older GHCs
  • Change the type of longestShortest

2.0

This is a major redesign of the API. Notable changes:

  • The lexer now supports parsing the longest prefix/shortest suffix (see longestShortest)
  • Instead of throwing an exception, we return a stream. The stream can be consumed directly, converted to a list or either-error-list of tokens.

1.1.1

Add tokensEither

1.1

Upgrade to srcloc 0.5

1.0.0.1

Signal a lexical error (instead of looping) when a regex does not consume any characters
