This is a very early prototype.
This package provides a way to interact with ghci (or, more precisely, cabal repl) from Atom.
To send command, or move through history, you can use the following commands when focused on repl command editor:
ide-haskell-repl:exec-commandide-haskell-repl:history-backide-haskell-repl:history-forwardide-haskell-repl:ghci-reload
Note that this commands are bound specifically to repl editor, which has CSS selector of atom-text-editor.ide-haskell-repl.
You can rebind those in your keymap, e.g.
"atom-text-editor.ide-haskell-repl":
'ctrl-enter': 'ide-haskell-repl:exec-command'
'ctrl-up': 'ide-haskell-repl:history-back'
'ctrl-down': 'ide-haskell-repl:history-forward'
Just don't forget to disable default bindings in ide-haskell-repl settings, if you don't want them.
