I am sure there is a better way to do this, so please let me know.
It somehow came up that someone wanted to feel JavaScripty when creating objects with methods.
People often follow the pattern below in JavaScript:
{ foo: function() { ... }, bar: function() { ... } }
How about in Ruby? Lucas Carlson talked about dynamically adding methods to classes through their objects in Ruby, and of course it is simple to do:
o = Object.new def o.foo puts 'whee' end
But what if you want to make this more JavaScripty:
x = {:a => lambda { puts 'whee' }, :b => lambda { puts 'foo' }}.to_o
x.a
A simple bit of code did this (without good checking of things):
class Hash def to_o o = Object.new self.each do |k,v| if v.is_a?(Proc) o.class.instance_eval do define_method(k.to_s, v) end end end o end end
