JavaScript syntax (ECMA-262 3rd edition) used as a lightweight data
interchange format.

:mod:`simplejson` exposes an API familiar to users of the standard library
:mod:`marshal` and :mod:`pickle` modules. It is the externally maintained
version of the :mod:`json` library contained in Python 2.6, but maintains
compatibility back to Python 2.5 and (currently) has significant performance
advantages, even without using the optional C extension for speedups.

Encoding basic Python object hierarchies::

    >>> import simplejson as json
    >>> json.dumps(['foo', {'bar': ('baz', None, 1.0, 2)}])
    '["foo", {"bar": ["baz", null, 1.0, 2]}]'
    >>> print(json.dumps("\"foo\bar"))
    "\"foo\bar"
    >>> print(json.dumps(u'\u1234'))
    "\u1234"
    >>> print(json.dumps('\\'))
    "\\"
    >>> print(json.dumps({"c": 0, "b": 0, "a": 0}, sort_keys=True))
    {"a": 0, "b": 0, "c": 0}
    >>> from simplejson.compat import StringIO
    >>> io = StringIO()
    >>> json.dump(['streaming API'], io)
    >>> io.getvalue()
    '["streaming API"]'

Compact encoding::

    >>> import simplejson as json
    >>> obj = [1,2,3,{'4': 5, '6': 7}]
    >>> json.dumps(obj, separators=(',',':'), sort_keys=True)
    '[1,2,3,{"4":5,"6":7}]'

Pretty printing::

    >>> import simplejson as json
    >>> print(json.dumps({'4': 5, '6': 7}, sort_keys=True, indent='    '))
    {
        "4": 5,
        "6": 7
    }

Decoding JSON::

    >>> import simplejson as json
    >>> obj = [u'foo', {u'bar': [u'baz', None, 1.0, 2]}]
    >>> json.loads('["foo", {"bar":["baz", null, 1.0, 2]}]') == obj
    True
    >>> json.loads('"\\"foo\\bar"') == u'"foo\x08ar'
    True
    >>> from simplejson.compat import StringIO
    >>> io = StringIO('["streaming API"]')
    >>> json.load(io)[0] == 'streaming API'
    True

Specializing JSON object decoding::

    >>> import simplejson as json
    >>> def as_complex(dct):
    ...     if '__complex__' in dct:
    ...         return complex(dct['real'], dct['imag'])
    ...     return dct
    ...
    >>> json.loads('{"__complex__": true, "real": 1, "imag": 2}',
    ...     object_hook=as_complex)
    (1+2j)
    >>> from decimal import Decimal
    >>> json.loads('1.1', parse_float=Decimal) == Decimal('1.1')
    True

Specializing JSON object encoding::

    >>> import simplejson as json
    >>> def encode_complex(obj):
    ...     if isinstance(obj, complex):
    ...         return [obj.real, obj.imag]
    ...     raise TypeError('Object of type %s is not JSON serializable' %
    ...                     obj.__class__.__name__)
    ...
    >>> json.dumps(2 + 1j, default=encode_complex)
    '[2.0, 1.0]'
    >>> json.JSONEncoder(default=encode_complex).encode(2 + 1j)
    '[2.0, 1.0]'
    >>> ''.join(json.JSONEncoder(default=encode_complex).iterencode(2 + 1j))
    '[2.0, 1.0]'


Using simplejson.tool from the shell to validate and pretty-print::

    $ echo '{"json":"obj"}' | python -m simplejson.tool
    {
        "json": "obj"
    }
    $ echo '{ 1.2:3.4}' | python -m simplejson.tool

    ``.write()``-supporting file-like object).

    If *skipkeys* is true then ``dict`` keys that are not basic types
    (``str``, ``unicode``, ``int``, ``long``, ``float``, ``bool``, ``None``)
    will be skipped instead of raising a ``TypeError``.

    If *ensure_ascii* is false, then the some chunks written to ``fp``
    may be ``unicode`` instances, subject to normal Python ``str`` to
    ``unicode`` coercion rules. Unless ``fp.write()`` explicitly
    understands ``unicode`` (as in ``codecs.getwriter()``) this is likely
    to cause an error.

    If *check_circular* is false, then the circular reference check
    for container types will be skipped and a circular reference will
    result in an ``OverflowError`` (or worse).

    If *allow_nan* is false, then it will be a ``ValueError`` to
    serialize out of range ``float`` values (``nan``, ``inf``, ``-inf``)
    in strict compliance of the original JSON specification, instead of using
    the JavaScript equivalents (``NaN``, ``Infinity``, ``-Infinity``). See
    *ignore_nan* for ECMA-262 compliant behavior.

    If *indent* is a string, then JSON array elements and object members
    will be pretty-printed with a newline followed by that string repeated
    for each level of nesting. ``None`` (the default) selects the most compact
    representation without any newlines. For backwards compatibility with
    versions of simplejson earlier than 2.1.0, an integer is also accepted
    and is converted to a string with that many spaces.

    If specified, *separators* should be an
    ``(item_separator, key_separator)`` tuple.  The default is ``(', ', ': ')``
    if *indent* is ``None`` and ``(',', ': ')`` otherwise.  To get the most
    compact JSON representation, you should specify ``(',', ':')`` to eliminate
    whitespace.

    *encoding* is the character encoding for str instances, default is UTF-8.

    *default(obj)* is a function that should return a serializable version
    of obj or raise ``TypeError``. The default simply raises ``TypeError``.

    If *use_decimal* is true (default: ``True``) then decimal.Decimal
    will be natively serialized to JSON with full precision.

    If *namedtuple_as_object* is true (default: ``True``),
    :class:`tuple` subclasses with ``_asdict()`` methods will be encoded
    as JSON objects.

    If *tuple_as_array* is true (default: ``True``),
    :class:`tuple` (and subclasses) will be encoded as JSON arrays.

    If *iterable_as_array* is true (default: ``False``),
    any object not in the above table that implements ``__iter__()``
    will be encoded as a JSON array.

    If *bigint_as_string* is true (default: ``False``), ints 2**53 and higher
    or lower than -2**53 will be encoded as strings. This is to avoid the
    rounding that happens in Javascript otherwise. Note that this is still a
    lossy operation that will not round-trip correctly and should be used
    sparingly.

    If *int_as_string_bitcount* is a positive number (n), then int of size
    greater than or equal to 2**n or lower than or equal to -2**n will be
    encoded as strings.

    If specified, *item_sort_key* is a callable used to sort the items in
    each dictionary. This is useful if you want to sort items other than
    in alphabetical order by key. This option takes precedence over
    *sort_keys*.

    If *sort_keys* is true (default: ``False``), the output of dictionaries
    will be sorted by item.

    If *for_json* is true (default: ``False``), objects with a ``for_json()``
    method will use the return value of that method for encoding as JSON
    instead of the object.

    If *ignore_nan* is true (default: ``False``), then out of range
    :class:`float` values (``nan``, ``inf``, ``-inf``) will be serialized as
    ``null`` in compliance with the ECMA-262 specification. If true, this will
    override *allow_nan*.

    To use a custom ``JSONEncoder`` subclass (e.g. one that overrides the
    ``.default()`` method to serialize additional types), specify it with
    the ``cls`` kwarg. NOTE: You should use *default* or *for_json* instead
    of subclassing whenever possible.

    *parse_constant*, if specified, will be called with one of the
