Localer is a tool that automatically detects missing I18n translations.

The goal is to preserve the integrity of translations. Localer parses and merges all application locales’ keys. At the next step, it searches for missing translations among the calculated keys.

Installation

Add this line to your application's Gemfile:

gem 'localer'

And then execute:

$ bundle

Or install it yourself as:

$ gem install localer

Usage

At the root directory of a Rails app, run:

$ localer check .

or for specific Rails path:

$ localer check /path/to/rails/application

CI integration

Localer is easy to integrate into your favorite CI workflow:

# .travis.yml

# other configuration options
script:
  - bundle exec bundle-audit
  - bundle exec rubocop
  - bundle exec rspec
  - bundle exec localer

or

# Rakefile

# other requirements
require 'localer/rake_task'
Localer::RakeTask.new()

task(:default).clear
task default: [:rubocop, :spec, :localer]

Support

Localer supports

• Ruby: 2.4, 2.5, 2.6, 2.7
• Rails: 5.0, 5.1, 5.2, 6.0

Configuration

The behavior of Localer can be controlled via the .localer.yml configuration file. It makes it possible to disable locales and keys. The file can be placed in your project directory.

Disable specific locale

By default, Localer enables all locales, but you can disable it:

Locale:
  EN:
    Enabled: false

Exclude keys globally

By default, Localer enables all keys, but you can disable keys started with specified string or by regex:

Exclude:
  - /population\z/
  - .countries.france

Exclude keys for specific locale

Locale:
  EN:
    Exclude:
      - /population\z/
      - .countries.france

Using Rake

Localer ships with a rake task. To use Localer's rake task you simply need to require the task file and define a task with it. Below is a rake task that will run localer:

require 'rubygems'
require 'localer'
require 'localer/rake_task'

Localer::RakeTask.new(:localer)

When you now run:

$ rake -T

you should see

rake localer  # Run Localer

Development

After checking out the repo, run bundle exec appraisal install to install dependencies for each appraisal. Then, run bundle exec appraisal rake to run the tests.
