Orderly.js: Orderly to JSONSchema Compiler
Orderly is a textual format for describing JSON. Orderly can be compiled into JSONSchema. It is designed to be easy to read and write.
I decided to give Jison a real-world spin by creating an Orderly to JSONSchema compiler for JavaScript. After about three days, interspersed with lots of eating and family vists, I have a working implementation, which I call Orderly.js.
Usage
var orderly = require("orderly");
var orderlySource = "array {};";
var jsonSchemaSource = orderly.compile(orderlySource);
var jsonSchemaObject = orderly.parse(orderlySource);
print(JSON.stringify(jsonSchemaObject));
An API for building parsers
I must say, Jison made this really simple. I don’t consider myself a speedy coder in the slightest, probably the opposite, but I was able to crank this out in a (holiday) weekend. Jison takes care of the hard parts of parsing, all you need is a working grammar* and the appropriate hooks. I’ll be writing more on Jison shortly.
*This can be non-trivial, though if the language you are parsing already specifies a grammar, as was the case with Orderly, you’re set!
