Search an Object's Methods in Ruby easily

ruby_method_search.rb

# Create a method 'search_methods' for the Object Class
class Object
  def search_methods(qry)
    self.methods & self.methods.select { |m| m.to_s.include? qry.to_s }
  end
end

# Now search methods for any Ruby Object
Array.search_methods 'enum'          # => [:to_enum, :enum_for]
Player.last.search_methods :trust    # => [:untrust, :untrusted?, :trust]
"hello".search_methods "to_"         # => [:to_i, :to_f, :to_s, :to_str, :to_sym, :to_r, :to_c, :to_enum]
