NAME

Locale::CLDR - A Module to create locale objects with localisation data from the CLDR

VERSION

Version 0.0.4

SYNOPSIS

This module provides a locale object you can use to localise your output. The localisation data comes from the Unicode Common Locale Data Repository.

USAGE

my $locale = Locale::CLDR->new('en_GB');

or

my $locale = Locale::CLDR->new(language_id => 'en', territory_id => 'gb');

ATTRIBUTES

These can be passed into the constructor and all are optional.

language_id

A valid language or language alias id, such as en

script_id

A valid script id, such as latn or Ctcl. The code will pick a likely script depending on the given language if non is provided.

territory_id

A valid territory id or territory alias such as GB

variant_id

A valid variant id. The code currently ignores this

extensions

A Hashref of extension names and values. This is currently ignored but future releases will use it to override various assumptions such as calendar type and number type

Methods

The following methods can be called on the locale object

id()

The local identifier. This is what you get if you attempt to stringify a locale object.

likely_language()

Given a locale with no language passed in or with the explicit language code of und, this method attempts to use the script and territory data to guess the locales language.

likely_script()

Given a locale with no script passed in this method attempts to use the language and territory data to guess the locales script.

likely_territory()

Given a locale with no territory passed in this method attempts to use the language and script data to guess the locales territory.

Meta Data

The following methods return, in English, the names if the various id's passed into the locales constructor. I.e. if you passed language = 'fr'> to the constructor you would get back French for the language.

name

The locales name. This is usually built up out of the language, script, territory and variant of the locale

language

The name of the locales language

script

The name of the locales script

territory

The name of the locales territory

variant

The name of the locales variant

Native Meta Data

Like Meta Data above this provides the names of the various id's passed into the locales constructor. However in this case the names are formatted to match the locale. I.e. if you passed language = 'fr'> to the constructor you would get back français for the language.

native_name

The locales name. This is usually built up out of the language, script, territory and variant of the locale. Returned in the locales language and script

native_language

The name of the locales language in the locales language and script.

native_script

The name of the locales script in the locales language and script.

native_territory

The name of the locales territory in the locales language and script.

native_variant

The name of the locales variant in the locales language and script.

Calenders

The Calendar data is built to hook into DateTime::Locale so that all Locale::CLDR objects can be used as replacements for DateTime::Locale's locale data

month_format_wide
month_format_abbreviated
month_format_narrow
month_stand_alone_wide
month_stand_alone_abbreviated
month_stand_alone_narrow

All the above return an arrayref of month names in the requested style.

Returns a string comprising of the concatenation of the first string, the mark and the second string. This should be used in preference to truncated_between when the truncation occurs on a word boundary.

truncated_word_end($string)

Adds the locale specific marking to show that the string has been truncated at the end. This should be used in preference to truncated_end when the truncation occurs on a word boundary.

Quoting

quote($string)

Adds the locales primary quotation marks to the ends of the string. Also scans the string for paired primary and auxiliary quotation marks and flips them.

eg passing z “abc” z to this method for the en_GB locale gives “z ‘abc’ z”

Miscellaneous

Yes or No?

is_yes($string)

Returns true if the passed in string matches the locales idea of a string designating yes. Note that under POSIX rules unless the locales word for yes starts with Y (U+0079) then a single 'y' will also be accepted as yes. The string will be matched case insensitive.

Lists

list(@data)

Returns data as a string formatted by the locales idea of producing a list of elements. What is returned can be effected by the locale and the number of items in data. Note that data can contain 0 or more items.

plural($number)

This method takes a number and uses the locales pluralisation rules to calculate the type of pluralisation required for units, currencies and other data that changes depending on the plural state of the number

=territory_aliases

This method returns a hash that maps valid territory codes to their valid aliases

=variant_aliases()

This method returns a hash that maps valid variant codes to their valid aliases

Information about weeks

Each of these methods returns a hash ref keyed on territory code. If the territory you are looking for is not in the hash use the territory_contained_by() method to work your way up the territory tree until you find a territory in the hash

week_data_min_days()

This method returns a hash ref keyed on territory id the value of which is the minimum number of days a week must have to count as the starting week of the new year

week_data_first_day()

This method returns a hash ref keyed on territory id the value of which is the three letter code of the first day of the week for that territory.

week_data_weekend_start()

This method returns a hash ref keyed on territory id the value of which is the three letter code of the first day of the weekend for that territory.

week_data_weekend_end()

This method returns a hash ref keyed on territory id the value of which is the three letter code of the last day of the weekend for that territory.

Territory Containment

territory_contains()

This method returns a hash ref keyed on territory id. The value is an array ref Each element of the array ref is a territory id of a territory immediately contained in the territory used as the key

territory_contained_by()

This method returns a hash ref keyed on territory id. The value of the hash is the territory id of the immediately containing territory.

Numbering Systems

numbering_system()

This method returns a hash ref keyed on numbering system id which, for a given locale, can be got by calling the default_numbering_system() method. The values of the hash are a two element hash ref the keys being type and data. If the type is numeric then the data is an array ref of characters. The position in the array matches the numeric value of the character. If the type is algorithmic then data is the name of the algorithm used to display numbers in that format.

Number Formatting

format_number($number, $format, $currency)

This method formats the number $number using the format $format. If the format contains the currency symbol ¤ then the currency symbol for the currency code in $currency will be used. If $currency is undef() then the default currency code for the locale will be used.

parse_number_format($format)

This method parses a CLDR format string into a hash ref containing data used to format a number. This should probably be a private function.

round($number)

This method returns $number rounded to an integer with values of .5 or more rounded up and less than .5 rounded down. It's here so that people who need a more sophisticated rounding mechanism can easily override it.

get_formatted_number($number, $format_hash)

This method takes the $format_hash produced by parse_number_format() and uses it to parse $number. It returns a string containing the parsed number.

get_digits()

This method returns an array containing the digits used by the locale, The order of the array is the order of the digits. It the locale's numbering system is algorithmic it will return [0,1,2,3,4,5,6,7,8,9]

default_numbering_system()

This method returns the numbering system id for the locale.

Measurement Information

measurement_system()

This method returns a hash ref keyed on territory, the value being the measurement system id for the territory. If the territory you are interested in is not listed use the territory_contained_by() method until you find an entry.

paper_size()

This method returns a hash ref keyed on territory, the value being the paper size used in that territory. If the territory you are interested in is not listed use the territory_contained_by() method until you find an entry.

Likely Tags

likely_subtags()

A full locale tag requires, as a minimum, a language, script and territory code. However for some locales it is possible to infer the missing element if the other two are given, e.g. given en_GB you can infer the script will be latn. It is also possible to fill in the missing elements of a locale with sensible defaults given sufficient knowledge of the layout of the CLDR data and usage patterns of locales around the world.

This function returns a hash ref keyed on partial locale id's with the value being the locale id for the most likely language, script and territory code for the key.

Currency Information

currency_fractions()

This method returns a hash ref keyed on currency id. The value is a hash ref containing four keys. The keys are

digits

The number of decimal digits normally formatted.

rounding

The rounding increment, in units of 10^-digits.

cashdigits

The number of decimal digits to be used when formatting quantities used in cash transactions (as opposed to a quantity that would appear in a more formal setting, such as on a bank statement).

cashrounding

The cash rounding increment, in units of 10^-cashdigits.

default_currency()

This method returns a hash ref keyed on territory. The value being the default currency id for that territory.

Calendar Information

calendar_preferences()

This method returns a hash ref keyed on territory id. The values are array refs containing the preferred calendar id's in order of preference.

default_calendar($territory)

This method returns the default calendar id for the given territory. If no territory id given it used the territory of the current locale.
