morejson 1.1.5

Wraps Python json, supporting more Python built-in types.

morejson is a drop-in replacement for Python’s json that handles additional built-in Python types.

import morejson as json
import datetime

json.dumps({'set': set([1,2]), 'complex': complex(32, -4)})

1   Installation

Install morejson with:

pip install morejson

2   Use

morejson implements the exact same API as Python’s built-in json module; the dump, dumps, load and loads methods wrap around their json counterparts without changing their interface, while any other function or attribute is left unchanged.

You can use any argument of these methods, including default, cls and object_hook; morejson will wrap around any kind of custom behaviour you provide, giving it priority over morejson’s encoding or decoding, and allowing you to use it with any custom JSON encoding/decoding code you have.

3   Supported Types

3.1   Built-in Types

  • set
  • frozenset
  • complex

3.2   datetime module types

  • date

  • timedelta
  • timezone

4.1   Installing for development


git clone

Install in development mode with test dependencies:

cd morejson
pip install -e ".[test]"

4.2   Running the tests

To run the tests, use:

nosetests --cover-erase --with-coverage --cover-package=morejson -d

4.3   Adding documentation

This project is documented using the numpy docstring conventions, which were chosen as they are perhaps the most widely-spread conventions that are both supported by common tools such as Sphinx and result in human-readable docstrings (in my personal opinion, of course). When documenting code you add to this project, please follow these conventions.
