jsonyx

jsonyx is a customizable JSON library for Python 3.8+. It is written in pure Python with an optional C extension for better performance and no dependencies.

Key Features

• JSON encoding, decoding and patching:

  >>> import jsonyx as json
  >>> json.dumps(["foo", {"bar": ("baz", None, 1.0, 2)}])
  '["foo", {"bar": ["baz", null, 1.0, 2]}]\n'
  >>> json.loads('{"foo": ["bar", null, 1.0, 2]}')
  {'foo': ['bar', None, 1.0, 2]}
  >>> json.apply_patch([1, 2, 3], {"op": "del", "path": "$[1]"})
  [1, 3]

• Pretty printing:

  {
      "foo": [1, 2, 3],
      "bar": {"a": 1, "b": 2, "c": 3}
  }

• Optionally supports these JSON deviations (specified in the documentation):

  {
      /* Block */ // and line comments
      "Missing commas": [1 2 3],
      "NaN and infinity": [NaN, Infinity, -Infinity],
      "Surrogates": "\ud800",
      "Trailing comma": [0,],
      "Unquoted keys": {key: "value"}
  }

• Detailed error messages:

  Traceback (most recent call last):
    File "/Users/wannes/Downloads/broken.json", line 1, column 99-381
      ...sList": {"GlossEntry": {"ID": "SGM..."GML", "XML"]}, "GlossSee": "markup"
