JavaScript and TypeScript Smart Pluralisation

##Overview

This module provides vue plugin for @new-inventor/pluralization service.

Instead of "zero | one | more" notation, we provide endings notation.

Installation

npm install -S @new-inventor/vue-pluralization
# or
yarn add @new-inventor/vue-pluralization

Usage

in main.ts/js

import PluralizationPlugin from '@new-inventor/vue-pluralization/PluralizationPlugin';
import ruWords from '@/ru.pluralization.json';
import {LocaleName} from "@new-inventor/pluralization/locales";
import RU, {RUWord} from "@new-inventor/pluralization/locales/RU";
import WordsList from "@new-inventor/pluralization/WordsList";

//...

Vue.use(PluralizationPlugin, {
  currentLocale: LocaleName.RU,
  locales: {
    [LocaleName.RU]: new RU(new WordsList<RUWord>(ruWords)),
  },
});

locales appears in next form: {: , ...} where instance must be child of Locale class

You can use plain text instead of LocaleName.RU to provide different locale or different locale name.

You can extend Locale class to implement your own locale.

in templates (value = 2)

<div>{{ value }} {{'билет' | pluralize(value, 'nominative')}}</div> -> 2 билета
// or
<div>{{ '{n} {билет|nominative}' | pluralizeTemplate(value)}}</div> -> 2 билета

in components

this.$pluralizer.pluralize('билет', 1, RUModifier.DATIVE);
// or
this.$pluralizer.pluralizeTemplate('{n} {билет|nominative}', 1);

You can pass plain text to modifier parameter instead of RUModifier.DATIVE

pluralization config should provide object like this (for Russian):

{
  "билет": {
    "base": "билет",
    "cases": {
      "nominative": ["", "а", "ов"],
      "genitive": ["а", "ов", "ов"],
      "dative": ["у", "ам", "ам"],
      "accusative": ["", "а", "ов"],
      "instrumental": ["ом", "ами", "ами"],
      "prepositional": ["е", "ах", "ах"]
    }
  },
  "подразделение": {
    "base": "подразделени",
    "cases": {
      "nominative": ["е", "я", "й"],
      "genitive": ["я", "й", "й"],
      "dative": ["ю", "ям", "ям"],
      "accusative": ["е", "я", "й"],
      "instrumental": ["ем", "ями", "ями"],
      "prepositional": ["е", "ях", "ях"]
    }
  }
}

where the key of map is the name of word to pluralize (you pass it in the template or to pluralize function)

the base param is the unchanged part of word.

the cases param is the list of word modifiers with array of [1, 2, 5] variants of word ending

You should not provide this file for English language because there are strict rule for plural words.

When you will implement your own locale you should provide your own config file if it is needed.
