Command-line validate with a schema reference

[petsuter]

Could a --schema-pointer <pointer> parameter be added to json-validate?

I would like to validate various similar JSON file with just one schema file containing various related schema definitions.

Example:

• foo.json contains {foo:3}
• foo_bar.json contains {foo:3, bar:4}]
• foos.json contains [{foo:3}, {foo:4}]
• schema.json contains:

{
    "$schema": "http://json-schema.org/draft-04/schema#",
    "definitions": {
        "foo": {
            "type": "object",
            "properties": {
                "foo": { "type": "integer" }
            },
            "required": ["foo"]
        },
        "foo_bar": {
            "allOf": [
                { "$ref": "#/definitions/foo" },
                {
                    "properties": {
                        "bar": { "type": "integer" }
                    },
                    "required": ["bar"]
                }
            ]
        },
        "foos": {
            "type": "array",
            "items": { "$ref": "#/definitions/foo" }
        }
    }
}

$ json-validate --schema-file=schema.json --schema-pointer=/definitions/foo --document-file=foo.json
$ json-validate --schema-file=schema.json --schema-pointer=/definitions/foo_bar --document-file=foo_bar.json
$ json-validate --schema-file=schema.json --schema-pointer=/definitions/foos --document-file=foos.json
