runCommand :: MonadIO m => FilePath -> [String] -> m (Either String String) Source #

Run the provided command with the provided arguments.

foreverWithDelay :: (MonadIO m, RealFrac d) => d -> IO () -> m ThreadId Source #

Execute the provided IO action at the provided interval.

foreverWithVariableDelay :: (MonadIO m, RealFrac d) => IO d -> m ThreadId Source #

Execute the provided IO action, and use the value it returns to decide how long to wait until executing it again. The value returned by the action is interpreted as a number of seconds.
