We need a better json library at Facebook. I'd discussed with Sönke the
possibility of taking vibe.d's json to std but he said it needs some
more work. So I took std.jgrandson to proof of concept state and hence
ready for destruction:
http://erdani.com/d/jgrandson.d
http://erdani.com/d/phobos-prerelease/std_jgrandson.html
Here are a few differences compared to vibe.d's library. I think these
are desirable to have in that library as well:
* Parsing strings is decoupled into tokenization (which is lazy and only
needs an input range) and parsing proper. Tokenization is lazy, which
allows users to create their own advanced (e.g. partial/lazy) parsing if
needed. The parser itself is eager.
* There's no decoding of strings.
* The representation is built on Algebraic, with the advantages that it
benefits from all of its primitives. Implementation is also very compact
because Algebraic obviates a bunch of boilerplate. Subsequent
improvements to Algebraic will also reflect themselves into improvements
to std.jgrandson.
* The JSON value (called std.jgrandson.Value) has no named member
variables or methods except for __payload. This is so there's no clash
between dynamic properties exposed via opDispatch.
Well that's about it. What would it take for this to become a Phobos
proposal? Destroy.
