Erlang for NetBeans (ErlyBird) Recent Updates

Erlang for NetBeans (ErlyBird) has been put on the NetBeans' mercurial trunk. I added a changelog page on http://wiki.netbeans.org/ErlangChangelog, where you can learn the latest progressing.

Here is a summary of recent updates:

20080223

  • Instant rename, or refactoring for local vars and functions (put caret on var or function name, press CTRL+R)
  • Fixed: syntax broken for packaged import attribute
  • Fixed: syntax broken for wild attribute
  • Completion suggestions will search on project's own paths only
  • Track GSF changes: reindex performance was improved a lot; Can live with other GSF based language support now (Ruby, Groovy etc)

ErlyBird 0.16.0 will be available soon.

Working with NetBeans Mercurial Repository

It was the second time I encountered this issue, I don't know why, so, I just upgraded my Mercurial from 0.9.4 to 0.9.5, and tried to get a new clone. I typed: 

hg clone http://hg.netbeans.org

Everything seemed going smoothly, I had a new repository now. I copied my old hgrc to replace the un-configured one, and typed ant build, guess what? I got a lot of package javax.help does not exist, build failed. I knew that was because of that the binary files were not downloaded properly. It seemed I should leave the original hdrc there, and let ant hook the external.py. So I removed all extra lines except the original content of hgrc: 

[paths]
default = http://hg.netbeans.org/main/

And tried ant build again, this time it went smoothly again.

LESSON: Do not modify hgrc before you do first "ant build", which will hook external.py and add "decode", "encode" automatically.

Scala for NetBeans: Debugger Modules are Available for Test

=== Updated Feb 5 ==>
I just fixed a defect of debugger modules, the updated modules will be available after new nightly build successfully. Since the underlaying changes of NetBeans APIs, you may need to download a new nightly build.
===

Scala Debugger modules are available for preview and test, which can be installed via Update Center for newest nightly build version of NetBeans (I tested on NetBeans IDE 6.1 200802040003). Debug feature includes two modules: Scala Debugger and Scala Debugger Projects Integration (you can click on "Name" in "Available Plugins" tab to find them), for more getting started information, please see http://wiki.netbeans.org/Scala

Google Group:

Known Issues:

  • "Run to cursor" does not work yet
  • "Step into Scala standard library's code" is not supported yet
  • "Add watches" is not supported yet
  • Complex condictions are not tested yet

Adventure with Nightly Build:

  • Nightly build version of NetBeans changes frequently, please check updates frequently too: "Tool"->"Plugins"->"Reload Category" (please update all available modules, including those not relating to Scala). If things are broken, re-download a new nightly build and try ...
