The new written Scala plugins for NetBeans are available for public test now, which can be installed on NetBeans 6.1 RC, and latest NetBeans nightly build. To get start, please visit http://wiki.netbeans.org/Scala
The following features are ready for test:
Syntax highlighting
Auto-indentation
Brace completion
Formatter
Outline navigator
Occurrences mark for local variables and function
Instance rename for local variables and function
Go-to-declaration for local variables and function
Scala project
Basic debugger
And with known issues:
Auto-completion it not full supported yet and not smart
There is no parsing errors recovering yet
Semantic errors are not checked on editing, but will be noticed when you build project
Due to the un-consistent of Scala's grammar reference document, there may be some syntax broken issues
BTW, Fortress editing plugin is also available on "Last Development Build" update center, see the installation part of http://wiki.netbeans.org/Scala to get it installed. It's a very alpha stage plugin.
And, Erlang plugins are also available from "Last Development Build" update center too, that is, you can install and use Erlang plugins with Ruby, Scala, JavaScript on the same NetBeans IDE (6.1 RC or nightly build). Thanks to Tor's work, the indexing performance has been improved a lot.
Erlang plugin will be rewritten in the near future too.
