buildbox- Rehackable components for writing buildbots and test harnesses.



A simple ''cron'' loop. Used for running commands according to a given schedule.



cronLoop :: Schedule (Build ()) -> Build ()Source

Given a schedule of commands, run them when their time is due. Only one command is run at a time. If several commands could be started at a specific moment, then we take the one with the earliest potential start time. If any command throws an error in the Build monad then the whole loop does.
