I18n::Env::Config

Set I18n.locale based on the environment variables that control the locale.

This is for Desktop applications only. For web application see http_accept_languge or http-accept.

Usage

require "i18n"
require "i18n/env/config"

I18n.config = I18n::Env::Config.new

Now I18n.locale will be derived from the user's environment.

Environment Variables

The following environment variables are searched, in order:

1. LANGUAGE
2. LC_ALL
3. LC_MESSAGES
4. LANG

(Just like gettext).

If an exact match is not found, the list is reevaluated using the locale's parent(s). E.g., if en_US is not found, we see if en is available.

Installation

Add this line to your application's Gemfile:

gem "i18n-env-config"

And then execute:

$ bundle

Or install it yourself as:

$ gem install i18n-env-config
