Using macports version of ruby (and irb), I noticed that the lovely and wonderful tab autocompletion wasn’t working: ` $ irb –simple-prompt
“foo”.cap (The tab key! It does nothing!) `
So you can see that I was hitting tab expecting to see .cap resolve to .capitalize but it did nothing. I’m not quite sure if this has been broken for a long time or forever. On Linux, irb seems to just work. So I found a fix out on the ‘tubes.
sudo gem install bond
$ cat ~/.irbrc
require 'rubygems';
require 'bond';
Bond.start
And now the tab is delicious.
`» “foo”.cap [tab]
“foo.capitalize => “Foo”`
Now while you’re at it, might as well get the color going with wirble:
sudo gem install wirble
Add some more lines to .irbrc. Now our .irbrc looks like this:
$ cat ~/.irbrc
require 'rubygems'
require 'wirble'
require 'bond'
Wirble.init
Wirble.colorize
Bond.start
Irb will have color and [tab] now which you can see in the screenshot right there. The colors can be customized in wirble but it seems to be limited to ANSI terminal colors. I wish the terminal would support RGB #html_codes, you could really go crazy and port some of the awesome Textmate themes over to the irb term.
