hi all,
in this (http://pastie.caboo.se/97662 ) code :
module Kernel
def expected_argument_list
2
end
def before (name)
puts :hola
define_method(name){
if expected_argument_list==1
yield :only_one
else
yield :one,:two
end
}
end
end
class A
before :foo do |*args|
puts second
end
before :foo do |first , second|
puts second
end
end
a = A.new
a.foo
Does anyone know of a way to determine what argument list was
specified when the block is created?
i mean i want to implement the function expected_argument_list, to
return the length of the argument list that the block expected.
Probably is not possible to do that :(
When are defined the variables of the block, in the class definition
time, or after the yield call?
Thanks
