cldr

A module that allows you to extract a bunch of locale-specific information from the <a href="http://cldr.unicode.org/">Unicode CLDR</a> (Common Localization Data Repository), including:

• Date, time, and date-time formats
• Date interval formats
• Number formats, symbols, and digits for all number systems
• Exemplar and ellipsis characters
• Day names, month names, quarter names, era names, and cyclic names
• Patterns for rendering lists of items (see the this-and-that module for an easy-to-consume version)
• Display names for languages, time zones, territories, scripts and currencies
• Plural rule functions (converted to JavaScript functions)
• Rule-based number formatting functions (converted to JavaScript functions)

The extraction code was originally written for the <a href="https://github.com/papandreou/inter">inter i18n library</a>, but can be used on its own.

To understand the data itself, you might need to dive into the <a href="https://www.unicode.org/reports/tr35/tr35-61/tr35.html">LDML specification</a>, which describes the schema of the CLDR XML files.

Comes bundled with the CLDR 45 release and isn't attempting to be backwards compatible with earlier versions.

Releases

See the changelog.

Usage

Make sure you have <a href="http://nodejs.org/">node.js</a> and <a href="http://npmjs.org/">npm</a> installed, then run:

$ npm install cldr

Now you're ready to create a node-cldr instance and take it for a spin:

var cldr = require('cldr');

console.log(cldr.extractTerritoryDisplayNames('fr'));

Output:

{ '142': 'Asie',
  '143': 'Asie centrale',
  '145': 'Asie occidentale',
  '150': 'Europe',
  [...]
  YT: 'Mayotte',
  ZA: 'Afrique du Sud',
  ZM: 'Zambie',
  ZW: 'Zimbabwe',
  ZZ: 'région indéterminée' }

Advanced users can also provide the path to another CLDR installation like this:

var cldr = require('cldr').load('/path/to/cldr');

Properties

cldr.localeIds

An array of locale ids for which data is available (656 in CLDR release 22.1). The locale ids are "normalized" to be all lower case with underscores separating the fragments. However, all methods that take a locale id as a parameter will accept any casing and both - and _ as separators.

cldr.calendarIds

An array of calendar ids for which data is available. In CLDR release 22.1:

[
  'buddhist',
  'chinese',
  'coptic',
  'dangi',
  'ethioaa',
  'ethiopic',
  'gregorian',
  'hebrew',
  'indian',
  'islamic',
  'islamicc',
  'iso8601',
  'japanese',
  'persian',
  'roc',
];

Methods

All the data extraction methods are synchronous, which means that XML documents that haven't already been loaded will be loaded using fs.readFileSync. The reasoning behind this is that the API would be awkward if all the extraction methods had to take callbacks. Also, node-cldr is unlikely to be used in a setting where performance is critical. However, if for some reason you want to avoid the synchronous loads, you can use cldr.load(<arrayOfLocaleIds>, cb) to load all the needed data in parallel before starting the extraction itself. Then all the needed documents will be loaded and ready.

cldr.extractLocaleDisplayPattern(localeId='root')

Extract a locale display pattern hash for a locale:

cldr.extractLocaleDisplayPattern('en_GB');
{ localePattern: '{0} ({1})',
  localeSeparator: '{0}, {1}',
  localeKeyTypePattern: '{0}: {1}' }

cldr.extractLanguageDisplayNames(localeId='root')

Extract a locale ID => display name hash for a locale:

cldr.extractLanguageDisplayNames('it').en;
('inglese');

cldr.extractSubdivisionAliases()

Subdivision aliases contain deprecated or alternative subdivision codes. Note that the returned code may be either a territory code, (such as 'cn71' => 'TW'), or a subdivision code.

cldr.extractSubdivisionAliases().czol;
({ replacement: 'cz71', reason: 'deprecated' });

cldr.extractSubdivisionDisplayNames(localeId)

Extract a subnational territory ID => display name hash for a locale. Codes follow the BCP47 standard, e.g. usca for California, USA. Note that these codes are similar but not identical to ISO 3166-2 codes. Unlike ISO 3166-2, CLDR never reuses a code.

For global regions and countries, see extractTerritoryDisplayNames

cldr.extractSubdivisionDisplayNames('en').dk85;
('Zealand');

cldr.extractTimeZoneDisplayNames(localeId='root')

cldr.extractTerritoryAliases()

Territory aliases contain deprecated or alternative territory codes.

cldr.extractTerritoryAliases().BU;

cldr.extractTerritoryDisplayNames('fr').US;
('États-Unis');

extractTerritoryContainmentGroups()

Get a flattened tree structure with information about which territories are contained in other territories. The territories are given by their id, so the result is locale-independent. Consult extractTerritoryDisplayNames for the translated display names.

}

cldr.extractPluralRuleFunction('en_GB', 'ordinal').toString();
function (n) {
    if (typeof n === "string") n = parseInt(n, 10);
    if (n % 10 === 1 && !(n % 100 === 11)) return "one";
    if (n % 10 === 2 && !(n % 100 === 12)) return "two";
    if (n % 10 === 3 && !(n % 100 === 13)) return "few";
    return "other";
}

cldr.extractPluralRuleFunction('ar').toString();

    if (n === 0) return "zero";
    if (n === 1) return "one";

}

cldr.extractRbnfFunctionByType(localeId='root'[, types])

Extracts RBNF (<a href="http://www.unicode.org/reports/tr35/tr35-29.html#Rule-Based_Number_Formatting">rule-based number formatting</a>) functions for a locale. The 'types' parameter specifies the names of the functions you want (defaults to all available), and the returned hash will contain the ones that were found plus their dependencies.

The original function names have been converted to camelCase and prefixed with render, and you need to use that naming convention when specifying the types array as well.

cldr.extractRbnfFunctionByType('en_GB').renderRomanUpper(2012);
('MMXII');
cldr.extractRbnfFunctionByType('de').renderSpelloutOrdinal(2323);
('zwei tausend drei hundert drei und zwanzigste');

Note that some of the generated functions expect to be able to call this.renderNumber(<number>, <icuNumberFormat>);. If there's demand for it, that can be made customizable, just file an issue.

cldr.extractNumberingSystem(numberingSystemId)

Extract information about a numbering system. The supported numbering systems can be retrieved as cldr.numberingSystemIds.

Most of the numbering systems will have a type of numeric and provide an array of digits that correspond to 0 through 9:

cldr.extractNumberingSystem('bali');
{ type: 'numeric',
  digits: [ '᭐', '᭑', '᭒', '᭓', '᭔', '᭕', '᭖', '᭗', '᭘', '᭙' ] }

For other more complicated numbering systems, the type will be algorithmic and there will be a rules property that is a string starting with render. In that case, use the RBNF function (see above) of that name for producing a number. These RBNF functions are the same in every locale, so you can just pass root:

cldr.extractNumberingSystem('cyrl')
{ type: 'algorithmic', rules: 'renderCyrillicLower' }
const rbnfs = cldr.extractRbnfFunctionByType('root', 'renderCyrillicLower')
rbnfs.renderCyrillicLower(1234)
'҂асл҃д'

Some of the algorithmic numbering systems will additionally refer to a specific locale:

cldr.extractNumberingSystem('jpan');
{ type: 'algorithmic',
  rules: 'renderSpelloutCardinal',
  locale: 'ja' }

In that case you should extract the RBNF rule from that specific locale to render the numbers:

const rbnfs = cldr.extractRbnfFunctionByType('ja', 'renderSpelloutCardinal');
const rbnfs.renderSpelloutCardinal(1234);
'千二百三十四'

cldr.extractDigitsByNumberSystemId()

Deprecated: Please use extractNumberingSystem() instead.

Extract a hash of number system id => digits array. For some exotic number systems, 'digits' is a string starting with render. In that case, use the RBNF function (see above) of that name for producing a number.

cldr.extractDigitsByNumberSystemId();
{ arab: [ '٠', '١', '٢', '٣', '٤', '٥', '٦', '٧', '٨', '٩' ],
