DateTime::Locale::FromData - Class for locale objects instantiated from pre-defined data


version 1.17


  my $locale = DateTime::Locale::FromData->new(%lots_of_data)


This class is used to represent locales instantiated from the data in the DateTime::Locale::Data module.


This class provides the following methods:

  • $locale->code

    The complete locale id, something like "en-US".

  • $locale->language_code

    The language portion of the code, like "en".

  • $locale->script_code

    The script portion of the code, like "Hant".

  • $locale->territory_code

    The territory portion of the code, like "US".

  • $locale->variant_code

    The variant portion of the code, like "POSIX".

  • $locale->name

    The locale's complete name, which always includes at least a language component, plus optional territory and variant components. Something like "English United States". The value returned will always be in English.

  • $locale->language

  • $locale->script

  • $locale->territory

  • $locale->variant

    The relevant component from the locale's complete name, like "English" or "United States".

  • $locale->native_name

    The locale's complete name in localized form as a UTF-8 string.

  • $locale->native_language

  • $locale->native_script

  • $locale->native_territory

  • $locale->native_variant

    The relevant component from the locale's complete native name as a UTF-8 string.

The following methods all return an array reference containing the specified data.

The methods with "format" in the name should return strings that can be used a part of a string, like "the month of July". The stand alone values are for use in things like calendars as opposed to a sentence.

The narrow forms may not be unique (for example, in the day column heading for a calendar it's okay to have "T" for both Tuesday and Thursday).

The wide name should always be the full name of thing in question. The narrow name should be just one or two characters.

  • $locale->month_format_wide

  • $locale->month_format_abbreviated

  • $locale->month_format_narrow

  • $locale->month_stand_alone_wide

  • $locale->month_stand_alone_abbreviated

  • $locale->month_stand_alone_narrow

  • $locale->day_format_wide

  • $locale->day_format_abbreviated

  • $locale->day_format_narrow

  • $locale->day_stand_alone_wide

  • $locale->day_stand_alone_abbreviated

  • $locale->day_stand_alone_narrow

  • $locale->quarter_format_wide

  • $locale->quarter_format_abbreviated

  • $locale->quarter_format_narrow

  • $locale->quarter_stand_alone_wide

  • $locale->quarter_stand_alone_abbreviated

  • $locale->quarter_stand_alone_narrow

  • $locale->am_pm_abbreviated

  • $locale->era_wide

  • $locale->era_abbreviated

  • $locale->era_narrow

The following methods return strings appropriate for the DateTime->format_cldr method:

  • $locale->date_format_full

  • $locale->date_format_long

  • $locale->date_format_medium

  • $locale->date_format_short

  • $locale->time_format_full

  • $locale->time_format_long

  • $locale->time_format_medium

  • $locale->time_format_short

  • $locale->datetime_format_full

  • $locale->datetime_format_long

  • $locale->datetime_format_medium

  • $locale->datetime_format_short

A locale may also offer one or more formats for displaying part of a datetime, such as the year and month, or hour and minute.

  • $locale->format_for($name)

    These are accessed by passing a name to $locale->format_for(...), where the name is a CLDR-style format specifier.

    The return value is a string suitable for passing to $dt->format_cldr, so you can do something like this:

      print $dt->format_cldr( $dt->locale->format_for('MMMdd') )

    which for the "en" locale would print out something like "08 Jul".

    Note that the localization may also include additional text specific to the locale. For example, the "MMMMd" format for the "zh" locale includes the Chinese characters for "day" (日) and month (月), so you get something like "8月23日".

  • $locale->available_formats

    This should return a list of all the format names that could be passed to $locale->format_for.

There are also some miscellaneous methods:

  • $locale->prefers_24_hour_time

    Returns a boolean indicating whether or not the locale prefers 24-hour time.

  • $locale->first_day_of_week

    Returns a number from 1 to 7 indicating the local first day of the week, with Monday being 1 and Sunday being 7.

  • $locale->version

    The CLDR version from which this locale was generated.
