So we in the Bulgarian Java User Group wanted to build Valhalla, and no IDE (Eclipse, Intellij Idea) supports it. We needed some simple text editor with some java support. And Sublime Text 3 (with Javatar) is the one we chose.
Installing Sublime Text 3 beta is straight forward. Installing Javatar is:
[openjdk@localhost valhalla]$ cd ~/.config/sublime-text-3/Packages/ [openjdk@localhost Packages]$ git clone git://github.com/spywhere/Javatar.git
Creating projects is a bit uneasy - create new project is actually called "Project -> Save as".
