Repl loop improvements #9

Closed luc-tielen closed 6 years ago

luc-tielen commented 6 years ago

Did the following:

respects interrupts now during option handling: helps if you have something like :q that calls abort, now it properly closes the REPL.
now handles 1 character long inputs (they were previously ignored)

I also noticed that <Ctrl-c> doesn't kill the REPL, is that behavior as intended? This could also be changed by changing line 205 to return pure Nothing on interrupt.

Also applied some minor refactorings (as mentioned by hlint 😅).

This ended up being much harder to get working all GHC versions than I initially thought. Maybe any tips on how you can quickly see if it works for older versions? Having to wait for Travis each time can be kind of slow.. 🤔
