Moonad is an interpreter for the esolang COW. I have written it for fun and to improve my Haskell skills, especially of Parsec and the monad transformers ReaderT and StateT.
First install Stack. Then compile the project:
stack buildTo run a file containing COW code (e.g. one of the examples in the original project):
stack exec Moonad-exe <filename>- Sean Heber (BigZaphod) for creating COW
