locale.setlocale problems

[Ksenia Marasanova]

Hi,

I have some problems with locale module.
On my workstation, changing locale doesn't have effect:

Python 2.3 (#1, Sep 13 2003, 00:49:11)
[GCC 3.3 20030304 (Apple Computer, Inc. build 1495)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

import locale
locale.setlocale(locale.LC_ALL, 'nl_NL') 'nl_NL' locale.format('%0.2f', 0.123) '0.12'

(It should return: 0,12)
On the server, it doesn't work at all:

Python 2.3 (#1, Jan 4 2004, 14:30:19)
[GCC 2.95.4 20020320 [FreeBSD]] on freebsd4
Type "help", "copyright", "credits" or "license" for more information. import locale
locale.setlocale(locale.LC_ALL, 'nl_NL')

Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "/usr/local/lib/python2.3/locale.py", line 381, in setlocale
return _setlocale(category, locale)
locale.Error: locale setting not supported

All I want to do, is format numbers with comma as decimal separator in
a web application. Is there some system libraries I have to install, to
make locale work?
And the last question: when I change locale in a Python application, it
affects only the current namespace, right? I hope so... :)

Thanks!
Ksenia.

Yes. OS X, unfortunately, doesn't really support the C locale APIs.
More precisely, it supports the functions, but they have no meaningful
effect. Python relies on the operating system here, so please bring
this up with your OS vendor.

>>> import locale
>>> locale.setlocale(locale.LC_ALL, 'nl_NL')

Likewise. Apparently, the operating system does not support that locale,
so Python cannot support it, either.

On freebsd4, this may help, but you would need to ask in a FreeBSD
newsgroup. On OS X, you just have to wait a couple more OS releases.

Not sure what a namespace is, in this context, but I guess the answer is
"yes".

Okay, I got it now. Thanks for the explanation.

is
"yes".

With 'namespace' I meant only the module when the locale is changed, so
it not affects other scripts that run at the same time on the system. I
misunderstood locale as being some system-wide 'registry' which
remembers the changes in it. (have some vague, bad memories about
changing locale in an ASP application... :-)

Thank you,
Ksenia.

FreeBSD is very strict for locale names. You should write it like this:

Python 2.3.4 (#2, Aug 21 2004, 20:09:51)
[GCC 3.4.2 [FreeBSD] 20040728] on freebsd5
Type "help", "copyright", "credits" or "license" for more information.

import locale
locale.setlocale(locale.LC_ALL, 'nl_NL.ISO8859-1') 'nl_NL.ISO8859-1' locale.format('%0.2f', 0.123)

'0,12'

There's a mailing list "py****@FreeBSD.org" for this purpose.

locale stuff are process-scope variable. (In FreeBSD, global libc
variable _CurrentRuneLocale). If you change the locale, it affects
all the namespaces/modules/threads but will not affect system
settings or other processes.
