ghci-daemon

This package allows you to wrap a "stack ghci" command and control it by sending commands to a network socket (or using the ghci-client executable).

How to use?

Start the daemon:

ghci-daemon

Send a command:

ghci-client -c ":reload"

(If you installed this package using stack you might want to use stack exec to call the executables.)

Easy Vim integration

ghci-daemon can be integrated into vim without any plugins.

1. Make sure the daemon is running.
2. Load vim's ghc compiler plugin.

   :compiler ghc
   

3. Set makeprg to ghci-client

   :set makepgr=ghci-client \-c:reload
   

Running :make will now reload your program and load the errors into your quickfix list.

Limitations

• The deamon only supports single threaded operation
• The client does not handle interrupts (e.g Ctrl-C) correctly (it just closes). If you have to stop the currently executed command, you have to use ghci-client --free after killing the client.
