If you can read something that can parse and emit Java .properties files, then no, not in standard ruby, and a quick google doesn't find much. You can hack something together... IO.readlines('some.properties').reject{|l|l=~/^\s*#/}. map{|l|l.split('=',2)} But I'm sure that misses a whole buncha edge cases, like backslash escaping, and Ant-style property substitution. If you mean some way to parse/emit key/value parse from/to a human-readable format... Hash and YAML. Devin
