Key benefits:

• Competely automated code generation from CLDR on update.
• Generated code automatically tested with CLDR fixtures.
• Both cardinal and ordinal forms supported.
• Rules for all languages are stored in single file in very compact form.

If you wish more high abstraction level of i18n support, see babelfish.

$ npm install plurals-cldr

Returns form name for given number. Number can be passed as string to keep tailing decimal zeros. If locale not supported, returns null.

var plural = require('plurals-cldr');

// Get cardinal form name
//
// Params:
//
// - locale
// - number (Number|String)
//
plural('ru', 0)   // -> 'many'
plural('ru', 1)   // -> 'one'
plural('ru', 2)   // -> 'few'
plural('ru', 19)  // -> 'many'
plural('ru', 0.5) // -> 'other'

Returns array of available forms for specified locale. If locale not supported, returns null.

Returns index of form for specified locale. That's convenient, if you wish to implement lookup from compact ordered list, like babelfish does.

If locale not supported, function returns -1.

Order of forms is the same for all languages: zero, one, two, few, many, other. Remove unavailable forms, and you will get indexes of each.

The same as above, but for ordinal forms.
