Éric Araujo mer...@netwok.org added the comment: Maybe rather than spending the effort maintaining a legacy API such as strftime, someone could look into implementing localized date formatting as defined by recent Unicode standards: http://unicode.org/reports/tr35/#Date_Format_Patterns This scheme is very elegant. I’d love to have built-in/stdlib support for it. Would it need to be implemented in C?

Eric Smith e...@trueblade.com added the comment: I think we're stuck with strftime for quite a while, no matter how ugly it is. datetime.__format__ uses it, for example. Although maybe it's possible to write an strftime-format to new-format translator. If we're going to take this on (re-writing strftime), I think the way to do it is to have it take the locale info as a parameter, and if that parameter is NULL then look up the info in the current locale. It looks like it's still a problem to find all of the info in the locale on all platforms, though. Finding the locale info is no doubt the tricky part, as someone said. I agree it would be easier to write this from scratch rather than track down the licensing on the existing patch. As it is, there's just not much code there. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue3173 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Hm, shouldn't the libc locale support offer the same set of locales and locale info that the libc strftime uses, on any platform? Or are there platforms whose libc strftime has better locale support than the libc getlocale implementation??? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue3173 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

STINNER Victor victor.stin...@haypocalc.com added the comment: The Qt library has its own strftime() implementation. The QLocale object has methods providing localized day and month names. For example, day names are implemented using a big ushort array (~20.000 bytes) which contains something like 'Sun;Mon;Tue;Wed;Thu;Fri;Sat;Sunday;Monday;Tuesday;Wednesday;Thursday;Friday;Saturday;S;M;T;W;T;F;S;7;1;2;3;4;5;6Dil;Wix;Qib;Rob;Kam;Jim;San;Dilbata;Wiixata;Qibxata;Roobii;Kamiisa;Jimaata;Sanbata;A;E;T;A;K;G;S;Aca;Etl;Tal;Arb;Kam;Gum;Sab;Acaada;Etleeni;Talaata;Arbaqa;Kamiisi;Gumqata;Sabti;1;2;3;4;5;6;7;So;Ma;Di;Wo;Do;Vr;Sa;Sondag;Maandag;Dinsdag;Woensdag;Donderdag;Vrydag;Saterdag;D;H;M;M;E;P;S;Die;H\xebn;Mar;M\xebr;(...)'. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue3173 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

STINNER Victor victor.stin...@haypocalc.com added the comment: Is nl_langinfo() function reliable? On any OS? Can we use it to get day name, abbreviated day name, month name and abbreviated month name? We should maybe start with an implementation in Python? It's easier to write code in Python than in C, and because it can be reused on other Python implementations. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue3173 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

That look like the BSD license *with* advertising clause... I am not a lawyer and I am not intimately familiar with PSF policies, but this license does not look too dissimilar to the profile module license: # Permission to use, copy, modify, and distribute this Python software # and its associated documentation for any purpose (subject to the # restriction in the following sentence) without fee is hereby granted, # provided that the above copyright notice appears in all copies, and # that both that copyright notice and this permission notice appear in # supporting documentation, ... Actually, I wonder if pydoc profile is technically in violation of the InfoSeek license. More likely, however, is that the license text in the source file is not authoritative and PSF has a more permissive license to this code. Skip, can you clarify where the strftime code in your patch came from? In your first post you said that it came from Tcl, so it may have ActiveState copyright on at least portions of it. On the other hand, unless strftime code is already published under an acceptable license, I think rewriting this code from scratch would be easier than tracking down the owners and asking them to contribute it to python. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue3173 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue3173] external strftime for Python?
New submission from Skip Montanaro [EMAIL PROTECTED]: Back in April we had a thread on xmlrpclib's problematic handling of dates before 1900: http://thread.gmane.org/gmane.comp.python.devel/93273/focus=93309 I'm still of the opinion that strftime() is the culprit and xmlrpclib is just an innocent bystander. Guido worried that to correct this we'd have to implement strftime() from scratch. I took a different approach and scouted around for an existing version of strftime() which we could suck into the distribution. I found a modified version of the BSD 4.4 strftime which came with (I see to recall) Tcl. The attached patch is against the py3k svn repo. It passes all tests as far as I can tell. Also, see http://bugs.python.org/issue1777412 which appears to be related. -- files: strftime.diff keywords: patch, patch messages: 68603 nosy: skip.montanaro priority: normal severity: normal status: open title: external strftime for Python? versions: Python 3.0 Added file: http://bugs.python.org/file10704/strftime.diff ___ Python tracker [EMAIL PROTECTED] http://bugs.python.org/issue3173 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
