Hi,

I’m having a couple of issues, unfortunately I couldn’t find anything on  
the internet. I’m using Ubuntu 7.04, with Ruby 1.8 installed with  
Synaptic.

- My irb doesnt autocomplete objects. When I press TAB, it autocompletes  
paths, but not methods, variables, etc. I have readlines installed.

- When I want to use Gem packages, I have to “include ‘rubygems’” before  
I can use any package. This wasnt the case in Windows, is it needed in  
Linux? Is there a way to avoid it?

- rbbr (Ruby Browser) can’t find Gnome/Gtk class documentation. I tried  
both the separate documentation package and downloaded the rbbr with api  
package, but it doesnt show any documentation for Gnome classes. I had  
this problem with all my Ubuntu installations. How can I get Gnome  
classes documented in Ruby Browser?

Thanks

Use this command:

irb -r irb/completion

OR put this line in your .irbrc file:

require ‘irb/completion’

Put

export RUBYOPT=‘rubygems’

in your shell’s env file (.zshenv for me).

Thanks a lot, it all worked very well.

Does anyone know how to fix the Gnome/Gtk documentation?
