Adding require_relative to IRB
Ruby 1.9 brought require_relative to the rubyists' life and it’s a nice thing. If you like it, you probably would like to use it in the interactive console.
For some reason I don’t yet know for sure, require_relative does not work on IRB:
>> require_relative "doom" LoadError: cannot infer basepath from (irb):2:in `require_relative' from (irb):2 from /Users/rodrigovieira/.rbenv/versions/1.9.3-p125/bin/irb:12:in `<main>' >>
So, I needed this an implemented this method and added it to the .irbrc file, nothing complex, but I found it useful still:
module Kernel def require_relative(file) $:.unshift Dir.pwd require file end end
Hope it is as helpful to you as it is to me, I’ll update this post whenever I found why this beloved method does not work in the console.
