schemax 1.0.1

district42 to JSON-Schema translator and vise versa

SchemaMaximal

district42 schemas ⇆ JSON Schema

Installation

pip3 install schemax

Usage

>>> import schemax
>>> from d42 import schema
>>> ExampleSchema = schema.str.len(1, 10)
>>> schemax.to_json_schema(ExampleSchema)
{'type': 'string', 'minLength': 1, 'maxLength': 10}

Also, you could use schemax to translate from JSON-Schema to d42 and generate tests interfaces (in future releases) via command line:

$ python3 -m schemax translate schema.json

Translation from JSON-Schema to d42-schema for schema.json:
schema.dict({
    'number': schema.int.min(1),
    optional('street_name'): schema.str,
    ...: ...
})

schema.json:

{
  "type": "object",
  "properties": {
    "number": { "type": "integer", "minimum": 1 },
    "street_name": { "type": "string" }
  },
  "required": ["number"],
  "additionalProperties": true
}
