=== DESCRIPTION Well, who needed another serialization format? Not me, but that's what I've made. Ruby Object Notation (Ron) is a textual format for the representation of Ruby data structures. It's somewhat like YAML, XML, or (most of all) JSON. However, since it is defined entirely within and as a subset of Ruby, it has the slick property that Ron expressions are legal Ruby. Thus it is very like JSON, except that it's Ruby-centered instead of being JavaScript-centered. Another way to look at Ron is as a purely declarative language for creating (almost) any type of Ruby data structure. Ruby already has formats for representing a literal Array, Hash, Set, String, Symbol, Integer, etc. Ron simply reuses the same notations for those data types. The major new feature of Ron is that it provides a literal syntax for representing arbitrary Ruby Objects. Say you have a class that looks like this: class K attr :a attr :b end A Ron literal that represents a K instance might look like this: K-{:@a=>1, :@b=>2} Better yet, if you provide setters as well as getters, you can leave off the @ signs: class K attr_accessor :a,:b end K-{:a=>1, :b=>2} This construct breaks encapsulation, so use the capability with moderation and prudence, please. An existing object can be rendered into Ron form with a call to Ron.dump: Ron.dump([1,2,3]) #=>"[1, 2, 3]" Ron.load is the inverse operation; it takes a Ron-formatted string and converts it back to a live Ruby object. (This is just an alias of eval.): Ron.load("K-{:@a=>1, :@b=>2}") #=> #<K:@a=2, @b=2> Most objects also have a #to_ron method which works just like Ron.dump; however, Ron.dump is the preferred form. In order to facilitate the dumping of bindings, two methods are provided that rip out the guts of a Binding and stuff them back in again: Binding#to_h and Binding.from_h. bugs and limitations Currently, some types of ruby object cannot be dumped. In some cases, this is because it is impossible to (correctly) dump those objects. In others, it's merely difficult. Here are the ones I think I should eventually be doing, mostly with ParseTree help: (anonymous) Class and Module Method UnboundMethod Proc These are very difficult, and I don't see how to approach them correctly (but it would be very nice...): Thread Continuation These are more or less impossible: File Dir Process IO
