Pyl10n is a localization (l10n) library for python
Pyl10n is a localization (l10n) library for python, written in 2008-2010.
BEWARE: This is old code, migrated to git. Previously, this was found at: https://code.osso.nl/projects/pyl10n
Pyl10n intends to replace the standard locale module which is not thread safe (locale.setlocale() updates the entire process’ locale settings). Pyl10n allows you to supply the language setting at conversion function call time or through a callback function that allows you to have a thread-specific language. E.g. for Django you could pass django.utils.translation.get_language which gets the currently selected language.
Its a complement to gettext solutions that do not depend on process-wide language settings.
Pyl10n has been tested with python 2.5 through 2.7 on Debian/Ubuntu Linux systems. It’s been known to work with Python 3 as well.
Python support before 2.7 cannot be guaranteed. Python support for 3 is not well tested.
The generated locale files should be packaged separately so you don’t need to fetch them when using pyl10n with only a handful of selected languages.
Import pyl10n as locale:
>>> import pyl10n as locale
Hardcode the current thread locale.
>>> locale.setlocale('nl_NL') >>> print(locale.currency(12345.67)) € 12345,67
Usually you’ll want to set a function that returns the current thread locale.
>>> getlocale = lambda: 'en_US' >>> locale.setlocalefunc(getlocale) >>> print(locale.format('%f', 12345.67, True, True)) 12,345.67
If you’re using your own locale files, you may set up the path like this:
$ ls path/to/locale/en/ -1p LC_ADDRESS LC_MEASUREMENT LC_MESSAGES/ LC_MONETARY LC_NAME LC_NUMERIC LC_PAPER LC_TELEPHONE LC_TIME
>>> locale.setlocalepath('path/to/locale') >>> locale.setlocale('en') >>> locale.teldom2string((31, 50, 1234567)) '(50) 1234567' >>> locale.setlocale('sv') >>> locale.teldom2string((31, 50, 1234567)) '050-1234567'
The data files are stored/read using pickle.
A quick selftest can be run:
$ python -c 'from pyl10n import selftest; selftest()' ...
Differences between the locale output and the pyl10n output may be attributed to an alternate/earlier source of locale date, or to custom adjustments (improvements) by me (to the Dutch or English locale files).
As of this writing, it is not complete yet. It does implement format() and currency() correctly (see http://bugs.python.org/issue1222 ) and it has most of the time formatting support that strftime(3) specifies.
In the near future (ha ha) it will support address formatting functions.
Look at the lists of finished and unfinished functions in the source.
