Scala Plugin for NetBeans - Rewrite in Scala #5: Refactoring Step One - Finding usages

I'm working on Refactoring features for NetBeans' Scala plugin, the first step is finding usages of class/method/val etc across project's source files, it works now. The next step will be renaming them.

Following snapshot shows class "ScalaDfn?" are used in 19 places, across 6 Scala sources

Awesome!

Caoyuan, you are reading my thoughts (I mean RFE in GG).

2. Blair -- 2009-09-02 16:00

Its all good its being stable and working really nicely here.

I've found a couple of bugs though, is there a place to report them?

Anyway, I was just popping on mainly to say thanks! Your work is making a huge difference to a lot of people, myself included. We are very much in awe of what you have got going.

@Blair, the official issue tracking is at: ​http://www.netbeans.org/issues/buglist.cgi?Submit+query=Submit+query&component=languages&subcomponent=scala

Thanks for reporting bugs.

@Andrew, I've found more potential issues of Scala's runtime libs by watching output from NetBeans' console window/logs

Caoyuan,

I'm ready to track NB console and report anything interesting for you - just give me an idea what is interesting at current context :-)

Say, I saw sych thing:

WARNING [org.netbeans.modules.editor.bracesmatching.MasterMatcher?]: Origin offsets out of range, origin = [562, 563], caretOffset = 561, lookahead = 1, searching backwards. Offending BracesMatcher?: org.netbeans.modules.scala.editor.ScalaBracesMatcher?@221a191b

except for reported exception wrt negative array size. As for

BinaryAnalyser?: Cannot read type: <A:Ljava/lang/Object;>Ljava/lang/Object;Lscala/collection/mutable/Vector...

  • I still see it.

BTW,
