Using locals by extending Binding

Comfortable work with locals in Ruby.rb

###Breaking news!
#Have you ever dreamed to extract all local variables from current context using ruby?

#Do you hate writing partials below style? :
=render partial: 'form_additional', locals: {f: f, shortname: shortname, expanded: expanded}

#I bet you do!

#Here is extension for Binding class which lets you to avoid writing hardcore something: something. It looks pretty workaround but there is no other way...

#first of all - extend Binding
class Binding
  def locals(specific = nil)
    Hash[
      (specific || self.eval('local_variables')).map{|v| [v.to_sym, self.eval(v.to_s)] }
    ]
  end
end

#using
[2] pry(main)> x=123
=> 123
[3] pry(main)> locs = binding.locals %w{x}
=> {"x"=>123}
[4] pry(main)> z='how are you dan'
=> "how are you dan"
[5] pry(main)> binding.locals %w{x z}
=> {"x"=>123, "z"=>"how are you dan"}

#or extracting just everything
[6] pry(main)> another_var = 'another'
=> "another"
[7] pry(main)> binding.locals
=> {"another_var"=>"another",
 "z"=>"how are you dan",
 "locs"=>{"x"=>123},
 "x"=>123,
 "_"=>"another",
 "_dir_"=>nil,
 "_file_"=>nil,
 "_ex_"=>nil,
 "_pry_"=>
etc....

#Since today you are able to write your partials
=render partial: 'somepartial', locals: binding.locals
=render partial: 'form' , locals: binding.locals(%w{f additional extended})
