Start `ghcid` and monitor a Haskell file for changes

ghcid path/to/Main.hs

Start `ghcid` with a specific command, such as loading a Stack or Cabal project

ghcid --command "stack ghci Main.hs"

Run an action (default `main`) on each file save

ghcid --run=action path/to/Main.hs

Set maximum height and width (default to console height and width)

ghcid --height=height --width=width path/to/Main.hs

Write full GHC compiler output to a file

ghcid --outputfile=path/to/output_file.txt path/to/Main.hs

Execute REPL commands (eg. `-- $> 1+1`) on each file save
