Ember Inflector is a library for inflecting words between plural and singular forms. Ember Inflector aims to be compatible with ActiveSupport::Inflector from Ruby on Rails, including the ability to add your own inflections in your app.

Ember CLI/NPM:

npm install --save ember-inflector

All methods are always available from Ember.Inflector, but in Ember CLI, you can always import instead:

import Inflector from 'ember-inflector';
import {singularize, pluralize} from 'ember-inflector';

Inflector.inflector.singularize("tacos"); // taco
Inflector.inflector.pluralize("taco"); // tacos

singularize("tacos"); // taco
pluralize("taco"); // tacos

// or if not using Ember CLI/ES6
Ember.Inflector.inflector.pluralize("taco"); // tacos

Pluralize a word

{{pluralize "taco"}} //tacos

Specify a count with the word, with the pluralization being based on the number of items.

{{pluralize 1 "taco"}} //1 taco
{{pluralize 2 "taco"}} //2 tacos

Specify a count with the word, with the pluralization being based on the number of items. Specify without-count=true to return on the word without the number.

{{pluralize 1 "taco" without-count=true}} //taco
{{pluralize 2 "taco" without-count=true}} //tacos

{{singularize 'octopi'}} //octopus
