A modern, pure-ruby streaming JSON parser/encoder modeled after yajl-ruby.
My intention is to create a pure-ruby, SAX-like, streaming JSON parser that allows the caller to build their own objects while parsing is happening. For example, by overriding the “found_string(str)” method, the caller can scan and parse out other types of objects (like say, Time or Date).
I have the parser working, and according to my testing it's able to generate matching output to the JSON gem, ActiveSupport and yajl-ruby but with one important difference. It has better UTF-8 support (specifically regarding surrogate character sequences) and [will eventually be] able to parse and encode to/from a stream in chunks.
Now that I have the parser working, my next step is to go back over the implementation and optimize the shit out of it. Help/suggestions would be greatly appreciated :)
