Search Methods in irb

Published in: Ruby 

URL: http://wiki.m001.net/technical/show/.irbrc

This allows you to search any INSTANCE or CLASS methods of any objects including rails models, which is helpful if you want to see the methods that you created yourself.

Plain TextExpand 
  1. #drop this in .irbrc
  2. class Object
  3.   def search_methods(string)
  4.     search_results = ["--","CLASS METHODS","--"]
  5.     search_results << self.methods.find_all{ |i| i.match(/#{string}/) }.sort 
  6.     search_results << ["--", "INSTANCE METHODS","--"]
  7.     search_results << self.instance_methods.find_all{ |i| i.match(/#{string}/) }.sort
  8.     return y(search_results)
  9.   end
  10. end
  11.  
  12. # now just call #Object.search_methods "your_search" in irb to find a method
