Yes, everyone, it is the moment you have all dreaded. A new version of pure python __builtin__s. This version contains nudity, sexual references, chr implemented using '%c'%i, an optimized ord, multiarg map and zip, and the new functions unichr, oct, hex, staticmethod, *attr (for * in (get,has,set)), isinstance, issubclass, and slice. I did not include classmethod as this seems to warrent further discussion. Stuff I think can be easily done in python that haven't been yet: dir, raw_input, reload, round, and xrange.

aehm, did i miss anything or was your attachment lost?

Oops. Sorry about that. The code, as before, is at http://fenton.balitmore.md.us/pypy.py

can't reach it from here. But that's probably just me. Somehow i get a lot of DNS-resolve problems though i can access *some* sites just fine. I don't yet see the pattern. holger

My apologies. I was in a rush to dash off the email, and my fingers slipped. -Scott On Mon, Jan 27, 2003 at 12:05:13AM +0100, Christian Tismer wrote:

Please, do us the favor and never type an URL in, but always browse to it and do a correct copy and paste.

many thanks - chris

i tested your code with the Python-2.2.2 test_builtin.py (found in Python-2.2.2/Lib/test, has some dependencies). 1) your code does not import cleanly (some typos here and there) 2) the tests fail right at 'abs', the first builtin because you don't throw a TypeError if the argument is not a number. I take it that you didn't seriously intend your code to be used as is. Nevertheless, it would be nice to have a python implementation of the builtin module that passes its CPython's tests. Also the docstrings should be copied from Python-2.3. This can be done automatically by writing a script and iterating over vars(__import__('__builtin__')) and using the inspect module. I hopefully can do this soon and check it into the upcoming repository. Or somebody else does it before me. Note, that you cannot automize extraction of signatures of the builtin callables in all cases. C-implemented builtins don't have signature-introspection methods but often have a conventional (and quite parseable) description in the first line of the docstring, e.g. >>> print abs.__doc__ abs(number) -> number cheers, holger

Don't worry. I'll take care of it. I just wanted to get a rough sketch out first

great. sorry if my posting sounded to harsh. holger

dir is probably possible but a bit tedious.

Don't know if this suits you, but some time ago I posted a dir version I rewrote dir based on C code to emulate 2.2 behaviour in 1.5.2. Didn't check if 'dir' code evolved since then.
