Alex + Happy + Lazy ByteString
Quick start: stack build && stack exec -- happy-alex-example
This is based mostly on my own work plus some bits from happy-plus-alex [1].
Some things to consider (when comparing with the more nicely written happy-plus-alex):
- I'd like to leave as much as possible outside of the .x and .y files.
- It is possible to pass the token position to the parsed result (see the construction of Let).
- Type-safe error wrapper.
- Uses lazy ByteString instead of String
- ghc-mod emacs syntax checking works only if you generate some nasty symlinks: (see TIPS)
