Ruby - print the variable name and then its value

Question

What is the best way to write a function (or something DSLish) that will allow me to write this code in Ruby. How would I construct the function write_pair?

Answer 1

This is a simple solution:

  def write_pair(variable)
    puts variable + eval(variable)
  end

This is more readable:

 def write_pair(variable)
    puts 'A' * 100
    puts variable + ': ' + eval(variable).inspect
    puts 'Z' * 100
 end

Invocation:

write_pair "variable"
