i18next-intervalPlural-postProcessor

Introduction

This is a i18next postProcessor enabling interval based plurals.

Getting started

Source can be loaded via npm, bower or downloaded from this repo.

# npm package
$ npm install i18next-intervalplural-postprocessor

# bower
$ bower install i18next-intervalplural-postprocessor

• If you don't use a module loader it will be added to window.i18nextIntervalPluralPostProcessor

Wiring up:

import i18next from 'i18next';
import intervalPlural from 'i18next-intervalplural-postprocessor';

i18next
  .use(intervalPlural)
  .init(i18nextOptions);

Usage sample

// given loaded resources
// translation: {
//    key1_one: '{{count}} item',
//    key1_other: '{{count}} items',
//    key1_interval: '(1)[one item];(2-7)[a few items];(7-inf)[a lot of items];',
//    key2_one: '{{count}} item',
//    key2_other: '{{count}} items',
//    key2_interval: '(1)[one item];(2-7)[a few items];'
// }

i18next.t('key1_interval', { postProcess: 'interval', count: 1 }); // -> one item
i18next.t('key1_interval', { postProcess: 'interval', count: 4 }); // -> a few items
i18next.t('key1_interval', { postProcess: 'interval', count: 100 }); // -> a lot of items

// if a interval is not specified i18next fallbacks to classic plural
i18next.t('key2_interval', { postProcess: 'interval', count: 1 }); // -> one item
i18next.t('key2_interval', { postProcess: 'interval', count: 4 }); // -> a few items
i18next.t('key2_interval', { postProcess: 'interval', count: 100 }); // -> 100 items

Setting own options

import i18next from 'i18next';
import intervalPlural from 'i18next-intervalplural-postprocessor';

intervalPlural.setOptions({
  // these are the defaults
  intervalSeparator: ';',
  intervalRegex: /\((\S*)\).*?\[((.|\n)*)\]/, // pre 3.0 /\((\S*)\).*{((.|\n)*)}/,
  intervalSuffix: '_interval'
});

i18next
  .use(intervalPlural)
  .init(i18nextOptions);
