wtypes 0.0.2

A extended trait and type system for python using jsonschema.

wtypes is an extended type and trait system for python.

• Documentation
• Pypi
• Tests

pip install wtypes

    from wtypes import *

wtypes provide:

• Extended type system python validation that feature a jsonschema and symbollic type composition.

    Integer, Float, Dict, List, Email, Uri, Color, Datetime, Regex
  

• Configurable dataclasses.

    class Thing(DataClass):
        name: String
        location: Uri|Jsonpointer
  
    class Thing(DataClass):
        name: String
        location: Uri|Jsonpointer
        
    Thing(name='wtypes', location='https://github.com/deathbeds/wtypes')
  

• Typed evented objects.

    class Thing(evented.DataClass):
        name: String
        location: Uri|Jsonpointer
        
    Thing(name='wtypes', location='https://github.com/deathbeds/wtypes')
  

• Generate examples of types with hypothesis_jsonschema and genson

    Uri.example(), Datetime.example(), Dict[{'a': Email}].example()
  

• Mixed python and jsonschema types

    t = Instance[range] | Integer
    t(10), t(range(10))
  

• future work will expand on semantic RDF type information.

Background

wtypes is inspired by traitlets - the core trait library used by IPython and jupyter - and pydantic - a jsonschema type system for python. Both pydantic and traitlets build type systems that can be validated. pydantic lacks interactive validate, a feature of traitlets. traitlets also provides an observable pattern for evented objects. Both pydantic and traitlets types are represented as python objects. wtypes includes features from these libraries in a composable type system.
