Lost in translation

Rails i18n web interface

Translate your apps with pleasure (sort of...) and for free. It's simple i18n web interface, build on top of twitter bootstrap, that one may find helpful in translating app by non-technicals.

Highly inspired by Copycopter by thoughtbot.

Features

1. Runs with your app - no need for external services
2. Support for array types, (ie. date.abbr_day_names)
3. Versioning translations - you can always check, how value did look like in past
4. Possibility to synchronize translations between environments or apps
5. Easy to install - works as an engine, comes with simple generator
6. You can always export all translations to plain old YAML file
7. Has build in wysiwyg editor (jQuery TE)

So... again - what is it and how to use it?

Lit is Rails engine - it runs in it's own namespace, by default it's avaulable under /lit. It provides UI for managing translations of your app.

Once you call I18n.t() function from your views, Lit is asked whether it has or not proper value for it. If translation is present in database and is available for Lit, it's served back. If it does not exists, record is automatically created in database with initial value provided in default option key. If default key is not present, value nil is saved to database. When app is starting, Lit will preload all keys from your local config/locale/*.yml files - this is why app startup may take a while.

To optimize translation key lookup, Lit can use different cache engines. For production with many workers redis is suggested, for local development hash will be fine (hash is stored in memory, so if you have many workers and will update translation value in backend, only one worker will have proper translation in it's cache - db will be updated anyway).

Keys ending with _html have auto wysiwyg support.

You can also export translations using rake task

$ rake lit:export

You may also give it extra env variables to limit the export results.

$ LOCALES=en,de rake lit:export

Installation

1. Add lit gem to your Gemfile

gem 'lit'

For Ruby < 1.9 use gem 'lit', '= 0.2.4', as next versions introduced new ruby hash syntax.

2. run bundle install

3. run installation generator bundle exec rails g lit:install (for production/staging environment redis is suggested as key value engine. hash will not work in multi process environment)

4. After doing above and restarting app, point your browser to http://app/lit

5. Profit!

You may want to take a look at generated initializer in config/initializers/lit.rb and change some default configuration options.

ToDo

• Versioning
• API
• Synchronization between environments
• Rewrite initializer
• Rewrite exporter (which is now code from copycopter)
• Support for array types (ie. date.abbr_day_names)
• Generator
• Support for wysiwyg
• Better cache
• Support for other key value providers (ie. Redis does not support Array types in easy way) (not applicable, as array storage works now with redis).
• Integration with ActiveAdmin
• Support for Proc defaults (like in I18n.t('not_exising_keys', default: lambda{|_, options| 'text'}) )

Testing

For local testing wwtd gem comes into play, run tests via: wwtd --local. Run migrations using command RAILS_ENV=test bundle exec rake db:migrate.
