I have been creating a gem recently and will usually want to open up an
irb session to play around with ideas. When opening the
irb session I had to configure the gem and it started to get annoying. I got envious of
rails console and decided to make my own
script/console for the gem.
Below is what it ended up looking like.
b = File.expand_path('../../lib/', __FILE__) $:.unshift lib unless $:.include?(lib) require 'my_gem' require 'irb' MyGem.configure do |config| config.name = "My Gem" end IRB.setup(nil) irb = IRB::Irb.new IRB.conf[:MAIN_CONTEXT] = irb.context irb.context.evaluate("require 'irb/completion'", 0) trap("SIGINT") do irb.signal_handle end catch(:IRB_EXIT) do irb.eval_input end
