Many OS X users know the productivity tool Alfred. Alfred is far more than a quick launcher that will let you operate your computer with the use of your keyboard.
Recently I created a very simple workflow, that adds a file action to *.sbt files. It will open the directory in Terminal and launch the Scala Build Tool. Just select the build.xbt file in Finder and hit CMD+OPT+\ to launch the file actions window of Alfred. It will show the option ‘ Launch SBT’.
Even better, it also works from the Eclipse Scala-IDE. You can download the workflow here.
