From 7115d1ec162b4059b3e8e8f84bd8d5898c1db025 Mon Sep 17 00:00:00 2001 From: Joey Hess Date: Wed, 14 May 2014 19:41:05 -0400 Subject: moved source code to src This is to work around OSX's brain-damange regarding filename case insensitivity. Avoided moving config.hs, because it's a config file. Put in a symlink to make build work. --- src/Propellor/Message.hs | 51 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 51 insertions(+) create mode 100644 src/Propellor/Message.hs (limited to 'src/Propellor/Message.hs') diff --git a/src/Propellor/Message.hs b/src/Propellor/Message.hs new file mode 100644 index 00000000..780471c3 --- /dev/null +++ b/src/Propellor/Message.hs @@ -0,0 +1,51 @@ +{-# LANGUAGE PackageImports #-} + +module Propellor.Message where + +import System.Console.ANSI +import System.IO +import System.Log.Logger +import "mtl" Control.Monad.Reader + +import Propellor.Types + +-- | Shows a message while performing an action, with a colored status +-- display. +actionMessage :: (MonadIO m, ActionResult r) => Desc -> m r -> m r +actionMessage desc a = do + liftIO $ do + setTitle $ "propellor: " ++ desc + hFlush stdout + + r <- a + + liftIO $ do + setTitle "propellor: running" + let (msg, intensity, color) = getActionResult r + putStr $ desc ++ " ...
