Readme for hjsonschema-1.0.0.0
[back to package description]
A Haskell implementation of the currentJSON Schema specification (Draft 4).
Requirespcre (pkgs.pcre in Nixpkgs).
NOTE: Schemas with circular references can cause infinite loops. hjsonschema does loop detection but it may not be solid yet -- please open an issue if you find a situation where it fails.
Example
Seehere.
Tests
Run all tests:
stack test
Run only local tests:
stack test hjsonschema:local
Run remote tests (makes GETs to json-schema.org, also temporarily starts an HTTP server on port 1234):
stack test hjsonschema:remote
Details
Goals
Be a correct and fast implementation of the spec.
Be a useful reference for implementers in other languages. Haskell's high level nature, expressive type system and referential transparency suit this purpose well.
Good Parts
Passes all the required tests in thelanguage agnostic test suite.
Very modular, which should make it easy to support future versions of the specification.
Bad Parts
Uses thepcre-heavy regular expression library for the "pattern" validator. It should use a library based on the ECMA 262 regex dialect, which thespec requires.
Currently doesn't support the optional
"format"validators.
Notes
JSON-Schema-Test-Suiteis vendored from commit # aabcb3427745ade7a0b4d49ff016ad7eda8b898bhere.src/draft4.jsonis from commit # f3d5aeb5ffbe9d9a5a0ceb761dc47c7c4c2efa68here.
