babel.support
Several classes and functions that help with integrating and using Babel in applications.
Format
Wrapper class providing the various date and number formatting functions bound to a specific locale and time-zone.
>>> fmt = Format('en_US', UTC) >>> fmt.date(date(2007, 4, 1)) u'Apr 1, 2007' >>> fmt.decimal(1.2345) u'1.234'date(self, date=None, format='medium')Return a date formatted according to the given pattern.
>>> fmt = Format('en_US') >>> fmt.date(date(2007, 4, 1)) u'Apr 1, 2007'see: babel.dates.format_date datetime(self, datetime=None, format='medium')Return a date and time formatted according to the given pattern.
>>> from pytz import timezone >>> fmt = Format('en_US', tzinfo=timezone('US/Eastern')) >>> fmt.datetime(datetime(2007, 4, 1, 15, 30)) u'Apr 1, 2007 11:30:00 AM'see: babel.dates.format_datetime time(self, time=None, format='medium')Return a time formatted according to the given pattern.
>>> from pytz import timezone >>> fmt = Format('en_US', tzinfo=timezone('US/Eastern')) >>> fmt.time(time(15, 30)) u'11:30:00 AM'see: babel.dates.format_time number(self, number)Return an integer number formatted for the locale.
>>> fmt = Format('en_US') >>> fmt.number(1099) u'1,099'see: babel.numbers.format_number decimal(self, number, format=None)Return a decimal number formatted for the locale.
>>> fmt = Format('en_US') >>> fmt.decimal(1.2345) u'1.234'see: babel.numbers.format_decimal currency(self, number, currency)Return a number in the given currency formatted for the locale.
see: babel.numbers.format_currency percent(self, number, format=None)Return a number formatted as percentage for the locale.
>>> fmt = Format('en_US') >>> fmt.percent(0.34) u'34%'see: babel.numbers.format_percent scientific(self, number)Return a number formatted using scientific notation for the locale.
see: babel.numbers.format_scientific
LazyProxy
Class for proxy objects that delegate to a specified function to evaluate the actual object.
>>> def greeting(name='world'): ... return 'Hello, %s!' % name >>> lazy_greeting = LazyProxy(greeting, name='Joe') >>> print lazy_greeting Hello, Joe! >>> u' ' + lazy_greeting u' Hello, Joe!' >>> u'(%s)' % lazy_greeting u'(Hello, Joe!)'
This can be used, for example, to implement lazy translation functions that delay the actual translation until the string is actually used. The rationale for such behavior is that the locale of the user may not always be available. In web applications, you only know the locale when processing a request.
The proxy implementation attempts to be as complete as possible, so that the lazy objects should mostly work as expected, for example for sorting:
>>> greetings = [ ... LazyProxy(greeting, 'world'), ... LazyProxy(greeting, 'Joe'), ... LazyProxy(greeting, 'universe'), ... ] >>> greetings.sort() >>> for greeting in greetings: ... print greeting Hello, Joe! Hello, universe! Hello, world!
value(self)(Not documented)
Translations
An extended translation catalog class.
load(cls, dirname=None, locales=None, domain=DEFAULT_DOMAIN)Load translations from the given directory.
param dirname: the directory containing the MO files param locales: the list of locales in order of preference (items in this list can be either Locale objects or locale strings) param domain: the message domain return: the loaded catalog, or a NullTranslations instance if no matching translations were found rtype: Translations merge(self, translations)Merge the given translations into the catalog.
Message translations in the specfied catalog override any messages with the same identifier in the existing catalog.
param translations: the Translations instance with the messages to merge return: the Translations instance (self) so that merge calls can be easily chained rtype: Translations
