Recently I’ve become disillusioned with the state of the JVM IDE: I haven’t touched Eclipse in anger in 3 years, and have no intention to do so anytime soon. IntelliJ on the other hand has served me decently, but suffers from too many odd bugs when dealing with Scala code to not be a minor nuisance in my workflow. Not only that, “modern” IDE’s are massive workspace hogs: try working with IntelliJ without at least a 1920x1200 resolution screen.
For these reasons, I’ve decided to try using Emacs for development for a month or so to see how it compares, and so far, so good.
Setting Up Emacs for Scala Development
Setting up Emacs for Scala development is fairly easy, just do the following:
Create a folder called ~/.emacs.d/scala-mode (in your home folder). You might already have an .emacs.d folder there, if not, create it.
Copy all contents from $SCALA_HOME/misc/scala-tool-support/emacs into ~/.emacs.d/scala-mode. I found that this folder is missing in the latest Scala 2.9.2 distribution, but you can get it from
