How can I set my shell to irb?

Ruby
1

Hi guys !

I’m running opensuse 11.0 . I would like to know 2 things :

  1. is it possible to change my shell from bash to irb ? if so,how ? ( I
    tried chsh , but with no success )
  2. is it possible to add methods to irb , by writing code in .irbrc ? If
    so , could I see an example ?

Thanks

  1. Try putting ‘exec /usr/bin/irb’ or equivalent into your current
    shell’s rc file. Is typing ‘irb’ really that painful? :slight_smile: Do you really
    countenance using irb as your main shell???
  2. Here’s mine:

load libraries

require ‘rubygems’
require ‘wirble’

start wirble (with color)

Wirble.init
Wirble.colorize
Wirble::Colorize.colors[:symbol_prefix] = :green
Wirble::Colorize.colors[:symbol] = :black

    You’ll need to add it to /etc/shells, otherwise chsh will not let you
    change to it.

echo ‘exec irb’ >> ~/.bashrc

npowell@delilah ~ $ grep -A 3 def .irbrc
def test
puts “Oh Hai!”
end
npowell@delilah ~ $ irb

test
Oh Hai!

This is interesting…

rush, a replacement for the unix shell (bash, zsh, etc) which uses
pure Ruby syntax.
