if $enabled != undef { do it } $enabled will have true or false or nothing/undef and it will be used for multiple things but I don''t want to do anything if it is ''undef''. Does this make sense?

That is the problem. :-) If its false/true I need to do stuff like if $enabled != undef { class { ''doit'': enabled => $enabled } # This here will use true or false to delete or add files for example } But if it''s undef I don''t even want to include the class. I''m guessing that if this is not a valid used syntax then I''ll have to do something like: if $enabled == true or $enabled == false { } But If its supported/valid then better. Thank you.

Thanks for the help. I opted to used strings on the variables, which to me is not good!!! (not a proper defined language) I should be able to use the types true, false and should be able to check for the nothing/nil/undef variable which I can''t and I think is bad. Once again, thanks for your help.

I concur, the boolean semantics can be less than optimal. Cheers, Felix -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
