Key benefits:

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

node.js:

$ npm install plurals-cldr

browser:

$ bower install plurals-cldr

make clean
make generate

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('plural-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.
