I was referring to Puppet DSL hashes, not hash in general as a data structure. Puppet hashes are data structures (code data structure even), yes, but expressed in a language and not a format. Expressed differently, a hash is code (puppet dsl code even), yaml is data. That means if you want to process this hash, you need to "parse/compile" it with the puppet code, compared to yaml that can be slurped in almost every language or computing environment. -- Brice Figureau My Blog: http://www.masterzen.fr/ -- You received this message because you are subscribed to the Google Groups "Puppet Developers" group.
