None in arguments to "".find and family of functions
by Facundo Batista 01 Nov '07

01 Nov '07

Hello people! I'm following the issue 1259 (http://bugs.python.org/issue1259) It basically says that this should be ok: "'asd'.find('s', None, None)", as the documentation says that "start" and "end" arguments behaves like in slices (right now it gives a TypeError). I created a patch, that solves the problem presented in that patch, as is suggested by Barry A. Warsaw. The patch touches three files: - Lib/test/string_tests.py: The test cases for this. - Objects/stringobject.c: Here I modified the string_find_internal() function, for PyArg_ParseTuple to not call directly to PyEval_SliceIndex: I just call it if the function received an argument and is not None. - Objects/unicodeobject.c: Here I needed to make the same in unicode_find(), unicode_rfind(), unicode_index(), and unicode_rindex(), so I created another function called _ParseTupleFinds(), for this family of functions, which handles the arguments and returns the needed info for each function. All the tests pass ok, I'm sending this mail to see if anybody could please review the patch before I apply it, as this is the first patch that I create in C. Feel free to ignore this mail if the patch is ok, :) Regards, -- . Facundo Blog: http://www.taniquetil.com.ar/plog/ PyAr: http://www.python.org/ar/

Explicit frame ref? (was Re: Declaring setters with getters)

This is semi-random tangent, but what if there was a way to explicitly refer to the current frame as a function argument? Then, the implicitness that creates these problems becomes explicit, instead. As it happens, I write virtually all my frame-oriented decorators to take a 'frame' argument anyway, and only guess when it's not supplied. So, having a convenient way to pass the argument would be the only thing needed. Unfortunately, to be really useful, the name or symbol used would have to be more compact than the name or other data that you planned to get from the frame in the first place. "sys._getframe()" itself, for example, is way too long of a string. Even shortening this to something like 'here()' still seems too inconvenient, but to go any less than that invites the use of line-noise for syntax. Oh well, it was worth a try.
