Capistrano variables are not really "variables". They use
method_missing to find them, so defined? won't work.
If you want to know if a variable has been set (using -S, -s, or set
()), you have to do something like this:
if variables.include?(:stage)
...
else
...
end

Hi,
Suppose I have this in my deploy.rb

puts stage
cap deploy -S stage=123
output:

cap deploy

I'm confused because both cases print "nee" but in the first case the
value of stage (123) is printed, so it must be defined.
On possible way to deal with it is wrap it in inside a begin/rescue
clause and check for a NameError but that's kinda ugly.
Can somebody explain why defined? doesn't work?
TIA
