[Caml-list] Announcing json-static: syntax magic for JSON

[Martin Jambon]

Hello,

I am releasing a syntax extension which translates quasi-OCaml type
definitions into converters from/to generic JSON data:

(version 0.9.0, BSD license)

JSON (JavaScript Object Notation) is a language-neutral data format, which
is readily available in JavaScript, but also for many other
programming languages thanks to its simplicity.

This tool uses the json-wheel library that Mika Illouz and myself released
a few weeks ago. Using the json-static facility is not mandatory at all,
but it can be a timesaver.

For example, the following declaration defines the type of a point object:

type json point = < x: float; y: float >

This automatically makes two functions available, with the following
signature:

val json_of_point : point -> Json_type.t
val point_of_json : Json_type.t -> point

Json_type.t is the type of any JSON data, as defined by the json-wheel
library.

A typical use of this library is illustrated by an HTTP client that
queries a web service which returns JSON data. There is an example of a
program that queries Yahoo!'s JSON web service:
