This library implements several JSON specs, like `JSON Schema`_,

`JSON Reference`_ and `JSON Pointer`_:

* It works on python 3.6 and above

* It is release under the `BSD license`_

Installation

------------

This library has only weak dependencies. You can simply use pip::

    $ pip install json-spec

Regading you needs, you can install more features. For example, this command

will enable colorated messages::

    $ pip install json-spec[cli]

This one will enable ip format for json schema::

    $ pip install json-spec[ip]

...

CLI Usage

---------

This module expose a cli command with multiple operations.

**json add** will transform the json document::

    $ json add '#/foo/1' --fragment-file=fragment.json --document-json='{"foo": ["bar", "baz"]}'

    $ echo '{"foo": ["bar", "baz"]}' | json add '#/foo/1' --fragment-json='first'

    $ json add '#/foo/1' --fragment-file=fragment.json --document-file=doc.json

    $ json add '#/foo/1' --fragment-file=fragment.json < doc.json

**json check** will test that a value at the target location is equal to a specified value::

    $ json check '#/foo/1' --fragment-file=fragment.json --document-json='{"foo": ["bar", "baz"]}'

    $ echo '{"foo": ["bar", "baz"]}' | json check '#/foo/1' --fragment-file=fragment.json

    $ json check '#/foo/1' --fragment-file=fragment.json --document-file=doc.json

    $ json check '#/foo/1' --fragment-file=fragment.json < doc.json

**json copy** will copy the value at a specified location to the target location::

    $ json copy '#/foo/1' --target='#/foo/2' --document-json='{"foo": ["bar", "baz"]}'

    $ echo '{"foo": ["bar", "baz"]}' | json copy '#/foo/1' --target='#/foo/2'

    $ json copy '#/foo/1' --target='#/foo/2' --document-file=doc.json

    $ json copy '#/foo/1' --target='#/foo/2' < doc.json

**json extract** will extract parts of your json document::

    $ json extract '#/foo/1' --document-json='{"foo": ["bar", "baz"]}'

    $ echo '{"foo": ["bar", "baz"]}' | json extract '#/foo/1'

    $ json extract '#/foo/1' --document-file=doc.json

    $ json extract '#/foo/1' < doc.json

**json move** will remove the value at a specified location and it will add the value to the target location::

    $ json move '#/foo/2' --target='#/foo/1' --document-json='{"foo": ["bar", "baz"]}'

    $ echo '{"foo": ["bar", "baz"]}' | json move '#/foo/2' --target='#/foo/1'

    $ json move '#/foo/2' --target='#/foo/1' --document-file=doc.json

    $ json move '#/foo/2' --target='#/foo/1' < doc.json

**json remove** will remove the value at a specified location::

    $ json remove '#/foo/1' --document-json='{"foo": ["bar", "baz"]}'

    $ echo '{"foo": ["bar", "baz"]}' | json remove '#/foo/1'

    $ json remove '#/foo/1' --document-file=doc.json

    $ json remove '#/foo/1' < doc.json

**json replace** will replace the value at a specified location with given fragment::

    $ json replace '#/foo/1' --fragment-file=fragment.json --document-json='{"foo": ["bar", "baz"]}'

    $ echo '{"foo": ["bar", "baz"]}' | json replace '#/foo/1' --fragment-file=fragment.json

    $ json replace '#/foo/1' --fragment-file=fragment.json --document-file=doc.json

    $ json replace '#/foo/1' --fragment-file=fragment.json < doc.json

**json validate** will validate your document against a schema::

    $ json validate --schema-file=schema.json --document-json='{"foo": ["bar", "baz"]}'

    $ echo '{"foo": ["bar", "baz"]}' | json validate --schema-file=schema.json

    $ json validate --schema-file=schema.json --document-file=doc.json

    $ json validate --schema-file=schema.json < doc.json

Library usage

-------------

Let say you want to fetch / validate JSON like objects in you python scripts.

You can extract member of an object with `JSON Pointer`_::

    from jsonspec.pointer import extract

    obj = {

        'foo': ['bar', 'baz', 'quux']

    }

    assert 'baz' == extract(obj, '/foo/1')

You can resolve member of any object with `JSON Reference`_::

    from jsonspec.reference import resolve

    obj = {

        'foo': ['bar', 'baz', {

            '$ref': '#/sub'

        }],

        'sub': 'quux'

    }

    assert 'quux' == resolve(obj, '#/foo/2')

You can describe you data with `JSON Schema`_::

    from jsonspec.validators import load

    # data will validate against this schema

    validator = load({

        'title': 'Example Schema',

        'type': 'object',

        'properties': {

            'age': {

                'description': 'Age in years',

                'minimum': 0,

                'type': 'integer'

            },

            'firstName': {

                'type': 'string'

            },

            'lastName': {

                'type': 'string'

            }

        },

        'required': [

            'firstName',

            'lastName'

        ]

    })

    # validate this data

    validator.validate({

        'firstName': 'John',

        'lastName': 'Noone',

        'age': 33,

    })
