I'm implementing a Zork I-like game to learn Racket. It is nowhere near complete. Or stable. It seems to work on latest (v8.0 [cs]).
./zork
All:
./test
Single file:
./test src/state.test.rkt
Watch for changes in the current directory with inotify-hookable:
inotify-hookable -q -f . -c 'clear && ./test'
