runStackT :: (MonadIO m, MonadBaseControl IO m) => Manager -> LogLevel -> config -> Bool -> StackT config m a -> m a

Run a Stack action.

runStackLoggingT :: MonadIO m => Manager -> LogLevel -> Bool -> StackLoggingT m a -> m a

Run the logging monad.

newTLSManager :: MonadIO m => m Manager

Convenience for getting a Manager

logSticky :: Q Exp

Write a "sticky" line to the terminal. Any subsequent lines will overwrite this one, and that same line will be repeated below again. In other words, the line sticks at the bottom of the output forever. Running this function again will replace the sticky line with a new sticky line. When you want to get rid of the sticky line, run logStickyDone.

logStickyDone :: Q Exp

This will print out the given message with a newline and disable any further stickiness of the line until a new call to logSticky happens.

It might be better at some point to have a runSticky function that encompasses the logSticky->logStickyDone pairing.
