Hi,
I’ve been defining modules for mixins with dynamic methods - here is a
test module:
module Odd
A_HASH = Hash[:a=>1, :b=>2]
AN_ARRAY = [:c, :d]
puts “hash keys: #{A_HASH.keys}”
puts “array values: #{AN_ARRAY}”
A_HASH.keys do |k|
puts “defining #{k}”
define_method(k) do
puts “#{k}”
end
end
AN_ARRAY.each do |k|
puts “defining #{k}”
define_method(k) do
puts “#{k}”
end
end
end
puts “methods: #{Odd.instance_methods}”
- The issue is that the A_HASH.keys code does not fire but the
AN_ARRAY.each code does as the following shows:
hash keys: [:a, :b]
array values: [:c, :d]
defining c
defining d
methods: [:c, :d]
Any ideas? - I am using ruby 1.9.2 pl180
Regards,
John
