Ruby: values of constants

Question

I'm using

MyModule.constants.each do |c|
  #my loop
end

How do I get the VALUE of each constant rather than its name?

Answer 1

You're looking for Module#const_get:

irb(main):014:0> MyModule.constants.each do |c|
irb(main):015:1*   puts(c.to_s + "  " + MyModule.const_get(c).to_s)
irb(main):016:1> end
MY_CONST  5
=> [:MY_CONST]
