  • Persisting IRB & Rails Console History

    Continuing the theme on customising IRB and Rails Console, add these lines to ~/.irbrc to persist the command history across console sessions:

    require 'irb/ext/save-history'
IRB.conf[:SAVE_HISTORY] = 100
IRB.conf[:HISTORY_FILE] = "#{ENV['HOME']}/.irb_history"

  • Awesome Print your IRB & Rails Console

    Awesome Print is a Ruby gem that prints prettified objects to the console. To avoid having to prepend ap to all your console commands, set it as the default formatter in IRB and Rails by adding the following to your ~/.irbrc:

    require 'awesome_print'
IRB::Irb.class_eval do
def output_value
ap @context.last_value
end
end

    Obviously, Awesome Print first needs to be installed: gem install awesome_print

    UPDATE: Awesome Print now includes a method to make the integration process easier.

    require 'awesome_print'
AwesomePrint.irb!
