This is [[pson]], a Rubygem for converting (some) Ruby objects into the (hypothetical) PostScript Object Notation. Numbers, strings, symbols, arrays, hashes, and Boolean values are supported.

You can convert a supported object by calling the

[to_postscript]

method, and the recursive converters (for

lists and dictionaries) follow this protocol, too. Thus, if you should implement, say, PostScript transformation matrices, paths, or code blocks by defining a new Ruby class, you can provide a compatible conversion mechanism by implementing the same method.

Note that there’s no matching parser.
