[Haskell-cafe] Cabal sandbox status in your ZSH prompt

Hi everyone, I made a simple script for my zsh setup that allows me to see whether am I in a cabalized sandbox environment or not. On my machine it looks like this: https://files.app.net/rjphjAG9.png The script itself is here: https://gist.github.com/co-dan/7963200 The result of checking for the sandbox is cached, which---as I've realized only moments ago---is probably unnecessary; it updates only when the user performs a `cabal` command or changes a directory. -- Sincerely yours, -- Daniil Frumin
