Summary: Switch to make pprint.pprint display ints and longs in hex
Initial Comment:
It would be nice to have some sort of switch or hook to
allow 'pretty-printing' of integers and long integers in
hexidecimal. So, for example:
>>> import pprint
>>> pprint.pprint(range(10)) # instead of this:
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> pprint.hexint = True
>>> pprint.pprint(range(10)) # you would get this:
[0x0, 0x1, 0x2, 0x3, 0x4, 0x5, 0x6, 0x7, 0x8, 0x9]
>>> pprint.pprint(range(0x100000000,0x100000010)) #
and this:
[0x100000000L,
0x100000001L,
0x100000002L,
0x100000003L,
0x100000004L,
0x100000005L,
0x100000006L,
0x100000007L,
0x100000008L,
0x100000009L,
0x10000000AL,
0x10000000BL,
0x10000000CL,
0x10000000DL,
0x10000000EL,
0x10000000FL]
>>>
Thanks,

In theory this should be possible by subclassing
pprint.PrettyPrinter and overwritting the format method:
import pprint
class MyPrettyPrinter(pprint.PrettyPrinter):
def format(self, object, context, maxlevels, level):
if isinstance(object, int):
return hex(object), True, False
else:
return pprint.PrettyPrinter.format(self, object,
context, maxlevels, level)
mpp = MyPrettyPrinter()
mpp.pprint(range(50))
This doesn't work reliable though: When the string is short
enough, format() seems to be bypassed and repr() is called
directly.
