 A simple, fast, extensible JSON encoder and decoder

 JSON (JavaScript Object Notation) <http://json.org> is a subset of

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

 interchange format.

 simplejson exposes an API familiar to uses of the standard library

 marshal and pickle modules.

 Encoding basic Python object hierarchies::

     >>> import simplejson

     >>> simplejson.dumps(['foo', {'bar': ('baz', None, 1.0, 2)}])

     '["foo", {"bar": ["baz", null, 1.0, 2]}]'

     >>> print simplejson.dumps("\"foo\bar")

     "\"foo\bar"

     >>> print simplejson.dumps(u'\u1234')

     "\u1234"

     >>> print simplejson.dumps('\\')

     "\\"

     >>> print simplejson.dumps({"c": 0, "b": 0, "a": 0}, sort_keys=True)

     {"a": 0, "b": 0, "c": 0}

     >>> from StringIO import StringIO

     >>> io = StringIO()

     >>> simplejson.dump(['streaming API'], io)

     >>> io.getvalue()

     '["streaming API"]'

 Compact encoding::

     >>> import simplejson

     >>> simplejson.dumps([1,2,3,{'4': 5, '6': 7}], separators=(',',':'))

     '[1,2,3,{"4":5,"6":7}]'

 Pretty printing::

     >>> import simplejson

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

     {

         "4": 5, 

         "6": 7

     }

 Decoding JSON::

     >>> import simplejson

     >>> simplejson.loads('["foo", {"bar":["baz", null, 1.0, 2]}]')

     [u'foo', {u'bar': [u'baz', None, 1.0, 2]}]

     >>> simplejson.loads('"\\"foo\\bar"')

     u'"foo\x08ar'

     >>> from StringIO import StringIO

     >>> io = StringIO('["streaming API"]')

     >>> simplejson.load(io)

     [u'streaming API']

 Specializing JSON object decoding::

     >>> import simplejson

     >>> def as_complex(dct):

     ...     if '__complex__' in dct:

     ...         return complex(dct['real'], dct['imag'])

     ...     return dct

     ... 

     >>> simplejson.loads('{"__complex__": true, "real": 1, "imag": 2}',

     ...     object_hook=as_complex)

     (1+2j)

     >>> import decimal

     >>> simplejson.loads('1.1', parse_float=decimal.Decimal)

     Decimal("1.1")

 Extending JSONEncoder::

     >>> import simplejson

     >>> class ComplexEncoder(simplejson.JSONEncoder):

     ...     def default(self, obj):

     ...         if isinstance(obj, complex):

     ...             return [obj.real, obj.imag]

     ...         return simplejson.JSONEncoder.default(self, obj)

     ... 

     >>> dumps(2 + 1j, cls=ComplexEncoder)

     '[2.0, 1.0]'

     >>> ComplexEncoder().encode(2 + 1j)

     '[2.0, 1.0]'

     >>> list(ComplexEncoder().iterencode(2 + 1j))

     ['[', '2.0', ', ', '1.0', ']']

 Using simplejson from the shell to validate and

 pretty-print::

     $ echo '{"json":"obj"}' | python -msimplejson.tool

     {

         "json": "obj"

     }

     $ echo '{ 1.2:3.4}' | python -msimplejson.tool

     Expecting property name: line 1 column 2 (char 2)

 Note that the JSON produced by this module's default settings

 is a subset of YAML, so it may be used as a serializer for that as well.
