These functions are well documented, so it's pointless to talk about major
changes to the API. Per the docs, getlocale should return an RFC 1766 language
code. If you want the platform result, use something like the following:
def getrawlocale(category=locale.LC_CTYPE):
return locale.setlocale(category)
>>> locale.setlocale(locale.LC_CTYPE, 'eng')
'English_United Kingdom.1252'
>>> getrawlocale()
'English_United Kingdom.1252'
>>> # the new CRT supports RFC1766
... locale.setlocale(locale.LC_CTYPE, 'en-GB')
'en-GB'
>>> getrawlocale()
'en-GB'
As I mentioned in issue 20088, the locale_alias dict is based on X11's
locale.alias file. It doesn't handle most Windows locale strings of the form
language_country.codepage.
On Windows, the _locale extension module could enumerate the system locales at
startup to build a mapping. Here's a rough prototype using ctypes (requires
Vista or later for the new locale functions):
import locale
from ctypes import *
from ctypes.wintypes import *
LOCALE_WINDOWS = 1
LOCALE_SENGLISHLANGUAGENAME = 0x1001
LOCALE_SENGLISHCOUNTRYNAME = 0x1002
LOCALE_IDEFAULTANSICODEPAGE = 0x1004
LCTYPES = (LOCALE_SENGLISHLANGUAGENAME,
LOCALE_SENGLISHCOUNTRYNAME,
LOCALE_IDEFAULTANSICODEPAGE)
kernel32 = WinDLL('kernel32')
EnumSystemLocalesEx = kernel32.EnumSystemLocalesEx
GetLocaleInfoEx = kernel32.GetLocaleInfoEx
EnumLocalesProcEx = WINFUNCTYPE(BOOL, LPWSTR, DWORD, LPARAM)
def enum_system_locales():
alias = {}
codepage = {}
info = (WCHAR * 100)()
@EnumLocalesProcEx
def callback(locale, flags, param):
if '-' not in locale:
return True
parts = []
for lctype in LCTYPES:
if not GetLocaleInfoEx(locale,
lctype,
info, len(info)):
raise WinError()
parts.append(info.value)
lang, ctry, code = parts
if lang and ctry and code != '0':
locale = locale.replace('-', '_')
full = '{}_{}'.format(lang, ctry)
alias[full] = locale
codepage[locale] = 'cp' + code
return True
if not EnumSystemLocalesEx(callback,
LOCALE_WINDOWS,
None, None):
raise WinError()
return alias, codepage
>>> alias, codepage = enum_system_locales()
>>> alias["English_United Kingdom"]
'en_GB'
>>> codepage['en_GB']
'cp1252'
>>> alias["Spanish_United States"]
'es_US'
>>> codepage['es_US']
'cp1252'
>>> alias["Russian_Russia"]
'ru_RU'
>>> codepage['ru_RU']
'cp1251'
>>> alias["Chinese (Simplified)_People's Republic of China"]
'zh_CN'
>>> codepage['zh_CN']
'cp936'
