Constant domain and procs

[David Espada]

Hi.

I have a question about constants in Ruby. Look at this code:

-------------------------------------
class Pepo
POPORRES = 4

def self.pepo(&block)
Pepo.new(&block)
end

def initialize(&block)
instance_eval(&block)
end
end

Pepo.pepo do
puts POPORRES
end

-------------------------------------

When executing, it fails with erro 'uninitialized constant POPORRES'. If proc
executes in Pepo class context, why it fails so?

Thank you very much for your aclarations.

Greets.

Constant lookup is done statically. However things have changed with
1.9 and there your test works. I don't have a reference handy but if
you search for changes in 1.9 you'll likely find material.

Kind regards

I have tested it and works perfectly with 1.9. Thank you very much.
