Erlang/Scala IDE based on NetBeans. With syntax checking, syntax highlighting, auto-completion, pretty formatter, occurrences mark, brace matching, indentation, code folding, function navigator, go to declaration, project management, shell console.
Much better than before, but still there are some issues: + No information about how to contact the developer team - mailing list? + "then" is not a keyword in Scala. The editor doesn't always highlight it correctly. + Type inference is unreliable. On more complex code, the editor flags false positive compilation errors. Unfortunately I have no code to share for an example. As said, it's getting better, but it's still not on par with the Eclipse based Scala IDE.
