Angular extract i18n and reverse-merge

This extends Angular CLI to improve the i18n extraction. It adds functionality to reverse-merge target translation files back to source code

Install

Prerequisites: i18n setup with defined target locales in angular.json - as documented here.

ng add ng-extract-i18n-reverse

Usage

ng extract-i18n # yes, same as before - this replaces the original builder

In your angular.json the target extract-i18n that can be configured with the following options:

Name	Default	Description

targetPath	none	Path to folder containing target file for further comparison
