Any way to properly pretty-print ordered dictionaries?

Question

I like the pprint module in Python. I use it a lot for testing and debugging. I frequently use the width option to make sure the output fits nicely within my terminal window

I've tested this unholy monkey-patch based hack on python3.5 and it works:

pprint.PrettyPrinter._dispatch[pprint._collections.OrderedDict.__repr__] = pprint.PrettyPrinter._pprint_dict


def unsorted_pprint(data):
    def fake_sort(*args, **kwargs):
        return args[0]
    orig_sorted = __builtins__.sorted
    try:
        __builtins__.sorted = fake_sort
        pprint.pprint(data)
    finally:
        __builtins__.sorted = orig_sorted

You make pprint use the usual dict based summary and also disable sorting for the duration of the call so that no keys are actually sorted for printing.
