This repo contains my config for the GHCI. It has a pretty prompt and loads language extensions and modules I use.
Save `ghci.conf` into `~/.ghc/` or as `~/.ghci` and it should work. For more information (like how to use on Windows) see [here](https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/ghci.html#the-ghci-files).
