Faster writer

Robert Brewer — Wed, 18 May 2005 22:23:25 -0000

I'd appreciate a faster writer. Here's one that runs in
75% of current in simple timeit tests:

def write(obj):
if isinstance(obj, dict):
items = [":".join((write(key), write(val)))
for key, val in obj.iteritems()]
chunk = ["{", ",".join(items), "}"]
elif isinstance(obj, list):
items = [write(item) for item in obj]
chunk = ["[", ",".join(items), "]"]
elif isinstance(obj, basestring):
chunk = ['"', obj, '"']
elif isinstance(obj, float):
return "%f" % obj
elif isinstance(obj, int):
if obj is True:
return "true"
elif obj is False:
return "false"
return str(obj)
elif obj is None:
return "null"
else:
raise ValueError("Not representable in JSON:
%s" % obj)
return "".join(chunk)

Look ma, no "import types"! :)

Replace unit tests with doctest tests

The unit tests in jsontest.py could be moved to doctest
tests in json.py itself with little effort.

Read the JSON hex digit format.

JSON allows hex digits to be embedded in strings using
the \uXXXX format. This is not implemented yet in json-py.
