yajs

   yajs is a simple package that provides a wrapper to the YAJL JSON
   lexer functions that allow tokenization of streams of JSON data
   without having to buffer up the whole data.

Examples:

    >>> from cStringIO import StringIO
    >>> from yajs import tokenize
    >>> for token in tokenize(StringIO('[1, 2, 3]')):
    ...     print token
    ...

    ('value', 1)
    ('value', 2)
    ('value', 3)
    ('end_array', None)
