To get some nice colors in your irb, you can install the gems awesome_print
and interactive_editor
. There should be a dot file (hidden file) in your home directory called .irbrc, if not just create it: sublime ~/.irbrc
.
gem install awesome_print
gem install interactive_editor
sublime ~/.irbrc
# ruby 1.8.7 compatible
require 'rubygems'
require 'irb/completion'
# interactive editor: use vim from within irb
begin
require 'interactive_editor'
rescue LoadError => err
warn "Couldn't load interactive_editor: #{err}"
end
# awesome print
begin
require 'awesome_print'
AwesomePrint.irb!
rescue LoadError => err
warn "Couldn't load awesome_print: #{err}"
end
# configure irb
#IRB.conf[:PROMPT_MODE] = :SIMPLE
# irb history
IRB.conf[:EVAL_HISTORY] = 1000
IRB.conf[:SAVE_HISTORY] = 1000
IRB.conf[:HISTORY_FILE] = File::expand_path("~/.irbhistory")
# load .railsrc in rails environments
railsrc_path = File.expand_path('~/.irbrc_rails')
if ( ENV['RAILS_ENV'] || defined? Rails ) && File.exist?( railsrc_path )
begin
load railsrc_path
rescue Exception
warn "Could not load: #{ railsrc_path } because of #{$!.message}"
end
