Online demo fails on case insensitive quoted strings #111

Closed bkil closed 4 years ago

bkil commented 4 years ago

I typed this grammar into the online demo:

A <- "a"

I expected it to work equivalently to this one:

A <- [aA]

However, it failed to compile with the following error message:

RacketContractError: memf: contract violation
  expected: (any/c . -> any/c)
  given: #<void>

Perhaps RacketScript does not implement char-alphabetic?

Fixed! I've added the missing functions to RacketScript and updated the demo site
