Netbeans 6.7 rc2/rc3 not ready for primetime?

Posted on by

Regarding my post yesterday about Netbean’s new 6.7 rc releases …

While my initial user experience was dandy, I have since discovered some show stopping bugs.

– When trying to import your plugins from a previous version (6.5 in my case), the screen that pop up mysteriously disables mouse clicks.
So you basically get stuck at a screen like this one …

Netbeans plugin export fail

… with no possible way of moving forward or back.
I had to kill the netbeans process and restart (happened in both rc2 and rc3).
To be fair, after restarting, I had no more problems … the plugins seemed to have imported just fine.

– I also discovered another odd problem while trying to work on migration files in Rails. After Netbeans produced one intellisense dropdown, the entire IDE would start freezing on every 2 or three key strokes … making itself unusable. I had this problem in rc2, no such problem with rc3.

– On the plus side, startup time is *a lot* faster than in 6.5. As soon as I loaded a few modules the startup speed went back to be cell-phone-customer-service slow, so no plus there.

+ The whole netbeans process seems to be self contained now. It used to be that when you looked in process explorer, you’d see Netbeans, nbexec and java, with the real size of netbeans contained in the Java process.
This, happily, is no longer the case. Netbeans still easily tops 200MB of memory though :\

– Trying to create a new rails app, the browse button on this screen does not work, terrible eh?

browse button on 'create new project' doesn't work in Netbeans 6.7

Fixing Ruby irb window console in Netbeans for Windows

Posted on by

PS: This worked for Netbeans 6.7 RC2, however it will HORRIBLY break any attempt to use irb from the windows command line

If you right click on a project in Netbeans then go to ‘Ruby Shell (IRB)’, you should get dropped into a ruby IRB window.

Unfortunately for most of you on windows, you might get this instead …

Netbeans irb window fails on windows

An easy fix is to go to irb.bat and comment out the first 7 lines of code so that it looks like this

#@echo off
#@if not "%~d0" == "~d0" goto WinNT
#\bin\ruby -x "/bin/irb.bat" %1 %2 %3 %4 %5 %6 %7 %8 %9
#@goto endofruby
#:WinNT
#"%~dp0ruby" -x "%~f0" %*
#@goto endofruby
#!/bin/ruby
#
#   irb.rb - intaractive ruby
#   	$Release Version: 0.9.5 $
#   	$Revision: 11708 $
#   	$Date: 2007-02-13 08:01:19 +0900 (Tue, 13 Feb 2007) $

require "irb"
 
if __FILE__ == $0
  IRB.start(__FILE__)
else
  # check -e option
  if /^-e$/ =~ $0
    IRB.start(__FILE__)
  else
    IRB.setup(__FILE__)
  end
end
__END__

How to uninstall a plugin in Rails

Posted on by

This one is simple, but I couldn’t find a decent google result for it.

Before you uninstall the plugin, you have to get its name … go to the vendors directory in your app folder and get the name of the folder

In this case the name of the plugin is “active_scaffold”

Go to the directory of the app you want the plugin removed from and type in

ruby script/plugin remove active_scaffold

or if you’re on a Linux box

./script/plugin remove active scaffold
