  • (Coming) Fixed: Go-To-Source across dependent Maven projects.

  • Much more responsive when typing and for code-completion
  • More refactoring: find usages, rename across opened projects
  • Breakpoint works everywhere
  • Better supporting for mixed Java/Scala project in both direction (Java is visible in Scala and vice versa)
  • Better integration with NetBeans maven plugin
  • Better code completion even for implicit methods (in most cases)
  • Better indentation and formatter for unfinished line after if, else, =, for, while, do etc
  • Better syntax highlighting for val/var, lazy val, implicit call, byname param, abstract method etc
  • Mark of implemented/overridden methods, click on mark will jump to super definition
  • Go to type ("Ctrl+O")
  • Select parts of code, press {, [, (, ", ` will add/replace surrounding pair, press ~ will remove them. Specially, press / will block-comment it
  • Reset Scala interactive parser when necessary, for instance: dependent libs changed (Right click on source, choose "Reset Scala Parser" in pop-up menu)
  • Output highlighted code to html ([File] -> [PrintToHTML...]) (Can be then copied/pasted to Word, PowerPoint, Keynote etc. See example)
  • Some basic hints, for instance: fixing import, unused imports
  • Code template now works, check or add your own via [Options/Preferences] -> [Editor] -> [Code Templates] -> [Scala]
