DateTime::Locale(3pm) User Contributed Perl Documentation DateTime::Locale(3pm)
NAME
DateTime::Locale - Localization support for DateTime.pm
VERSION
version 1.33
SYNOPSIS
use DateTime::Locale;
my $loc = DateTime::Locale->load('en-GB');
print $loc->native_name, "\n", $loc->datetime_format_long, "\n";
# but mostly just things like ...
my $dt = DateTime->now( locale => 'fr' );
print "Aujourd'hui le mois est " . $dt->month_name, "\n";
DESCRIPTION
DateTime::Locale is primarily a factory for the various locale subclasses. It also
provides some functions for getting information on all the available locales.
If you want to know what methods are available for locale objects, then please read the
DateTime::Locale::FromData documentation.
USAGE
This module provides the following class methods:
DateTime::Locale->load( $locale_code | $locale_name )
Returns the locale object for the specified locale code or name - see the
DateTime::Locale::Catalog documentation for the list of available codes and names. The
name provided may be either the English or native name.
If the requested locale is not found, a fallback search takes place to find a suitable
replacement.
The fallback search order is:
{language}-{script}-{territory}
{language}-{script}
{language}-{territory}-{variant}
{language}-{territory}
{language}
Eg. For the locale code "es-XX-UNKNOWN" the fallback search would be:
es-XX-UNKNOWN # Fails - no such locale
es-XX # Fails - no such locale
es # Found - the es locale is returned as the
# closest match to the requested id
Eg. For the locale code "es-Latn-XX" the fallback search would be:
es-Latn-XX # Fails - no such locale
es-Latn # Fails - no such locale
es-XX # Fails - no such locale
es # Found - the es locale is returned as the
# closest match to the requested id
If no suitable replacement is found, then an exception is thrown.
The loaded locale is cached, so that locale objects may be singletons. Calling
"DateTime::Locale->register_from_data", "DateTime::Locale->add_aliases", or
"DateTime::Locale->remove_alias" clears the cache.
DateTime::Locale->codes
my @codes = DateTime::Locale->codes;
my $codes = DateTime::Locale->codes;
Returns an unsorted list of the available locale codes, or an array reference if called in
a scalar context. This list does not include aliases.
DateTime::Locale->names
my @names = DateTime::Locale->names;
my $names = DateTime::Locale->names;
Returns an unsorted list of the available locale names in English, or an array reference
if called in a scalar context.
DateTime::Locale->native_names
my @names = DateTime::Locale->native_names;
my $names = DateTime::Locale->native_names;
Returns an unsorted list of the available locale names in their native language, or an
array reference if called in a scalar context. All native names use UTF-8 as appropriate.
DateTime::Locale->register_from_data( $locale_data )
This method allows you to register a custom locale. The data for the locale is specified
as a hash (or hashref) where the keys match the method names given in
DateTime::Locale::FromData.
If you just want to make some small changes on top of an existing locale you can get that
locale's data by calling "$locale->locale_data".
Here is an example of making a custom locale based off of "en-US":
my $locale = DateTime::Locale->load('en-US');
my %data = $locale->locale_data;
$data{code} = 'en-US-CUSTOM';
$data{time_format_medium} = 'HH:mm:ss';
DateTime::Locale->register_from_data(%data);
# Prints 18:24:38
say DateTime->now( locale => 'en-US-CUSTOM' )->strftime('%X');
# Prints 6:24:38 PM
say DateTime->now( locale => 'en-US' )->strftime('%X');
The keys that should be present in the hash are the same as the accessor methods provided
by DateTime::Locale::FromData, except for the following:
The *_code methods
While you should provide a "code" key, the other methods like "language_code" and
"script_code" are determined by parsing the code.
All "id" returning methods
These are aliases for the corresponding *code methods.
"prefers_24_hour_time"
This is determined by looking at the short time format to see how it formats hours,
"date_format_default" and "time_format_default"
These are the corresponding medium formats.
"datetime_format" and "datetime_format_default"
This is the same as the medium format.
"date_formats" and "time_formats"
These are calculated as needed.
"available_formats"
This should be provided as a hashref where the keys are things like "Gy" or "MMMEd"
and the values are an actual format like "y G" or "E, MMM d".
"locale_data"
This is everything you pass in.
LOADING LOCALES IN A PRE-FORKING SYSTEM
If you are running an application that does pre-forking (for example with Starman), then
you should try to load all the locales that you'll need in the parent process. Locales are
loaded on-demand, so loading them once in each child will waste memory that could
otherwise be shared.
CLDR DATA BUGS
Please be aware that all locale data has been generated from the CLDR (Common Locale Data
Repository) project locales data). The data is incomplete, and may contain errors in some
locales.
When reporting errors in data, please check the primary data sources first, then where
necessary report errors directly to the primary source via the CLDR bug report system. See
<http://unicode.org/cldr/filing_bug_reports.html> for details.
Once these errors have been confirmed, please forward the error report and corrections to
the DateTime mailing list, datetime AT perl.org.
AUTHOR EMERITUS
Richard Evans wrote the first version of DateTime::Locale, including the tools to extract
the CLDR data.

DONATIONS
If you'd like to thank me for the work I've done on this module, please consider making a
"donation" to me via PayPal. I spend a lot of free time creating free software, and would
appreciate any support you'd care to offer.
Please note that I am not suggesting that you must do this in order for me to continue
working on this particular software. I will continue to do so, inasmuch as I have in the
past, for as long as it interests me.
Similarly, a donation made in this way will probably not make me work on this software
much more, unless I get so many donations that I can consider working on free software
full time (let's all have a chuckle at that together).
To donate, log into PayPal and send money to autarch AT urth.org, or use the button at
<https://www.urth.org/fs-donation.html>.
