Best editors for Rails - Using Netbeans IDE for Ruby on Rails
Installing NetBeans IDE for Ruby and Ruby on Rails is simple enough.
Go to terminal type in:
$ netbeans
if its not already there, type in:
sudo apt-get install netbeans
Go into plugins and install the "ruby and rails" plugin - this should do everything you need.
I got version 6.8, it works great, seems like version 7 is not supported anymore with ruby officially but it is supported anyways. This version works for me.
Manual install:
Download the version you want from netbeans site:
http://netbeans.org/downloads/6.9.1/
select the ruby version.
Instructions are available there but you can download the .sh file
$ chmod +x <filename> (turned green for me)
$ sh <installer file> (running the installer script)
This guy does a much better job of explaining the process after: http://linuxhub.net/2010/06/install-netbeans-on-ubuntu-10-04/
Checking if it works:
Open netbeans and click "New Project"
You should see "Ruby" and "Ruby on Rails Project" on the side.
Congrats, its working!
