Robin

Robin is a build daemon for Haskell development.

Usage

robin (start | stop | build | watch | debug)

This daemon rebuilds a Cabalized Haskell project whenever a source file changes. It runs one of the following commands:

• ./robin.sh, if that file exists, or
• stack build, if stack.yaml exists, or
• cabal build, otherwise.

Commands

• start - if the current project doesn't already have a daemon, start one
• stop - stop the daemon for the current project
• build - show the output of the last build, or if a build is in progress, wait for completion and then show its output
• watch - take over the console, always showing the latest build output
• debug - like start, but doesn't daemonize

The default command is build.

Note: the current project is assumed to be the root of the git working copy which contains the current directory.

Vim integration

echo 'setlocal makeprg=robin' >> ~/.vim/ftplugin/haskell.vim

Alternatives

Similar functionality is built in to Stack:

stack build --file-watch
