Hook, or override const_set, and const_get

ruby-talk
1

I have seen some examples of hooking into const_missing; Howerver, I can't seem to find anything on const_set, and const_get, any ideas?

I tried opening class Module, ex.

class Module
   def const_set(cname, cval)
     ....
   end
end

Does not work. I realize this is very dangerous. Is there any other way to intercept when, ex

FOO="bar"

happens?

Thanks

a) Edit variable.c

b) Run your code through a ruby2ruby subclass that wraps up your const assignments with extra code.

Thanks Eric. Option a makes me think I am taking the wrong approach. Option b looks more attractive. Well at least I know I was not missing something easier.

Both options are pure evil and guaranteed to cause you pain.

What is your ultimate goal?
