Tr8n Core Library For Ruby

Tr8n core library for Ruby is a set of classes that provide translation functionality for any Ruby based application. The library uses Tr8n's TML (Translation Markup Language) that allows you to encode complex language structures in simple, yet powerful forms.

The library works in conjunctions with TranslationExchange.com service that provides machine and human translations for your application. In order to use the library, you should sign up at TranslationExchange.com, create a new application and copy the application key and secret.

Rails Integration

If you are planning on using Tr8n in a Rails application, you should use tr8n_rails_client_sdk gem instead.

https://github.com/tr8n/tr8n_rails_clientsdk

Installation

To install the gem, use:

gem install tr8n_core

Registering Your App

Before you can proceed with the integration, please register with http://translationexchange.com and create a new application.

At the end of the registration process you will be given a key and a secret. You will need to enter them in the initialization function of the Tr8n SDK.

Usage

The library can be invoked from the IRB. To use tr8n client you must require it, and instantiate the application with the key and secret of your app from tr8nhub.com:

irb(main)> require 'tr8n_core'
irb(main)> app = Tr8n.session.init(KEY, SECRET)

Now you can use the application to get any language registered with your app:

irb(main)> english = app.language('en-US')
irb(main)> russian = app.language('ru')
irb(main)> spanish = app.language('es')
irb(main)> chinese = app.language('zh')

Simple example:

irb(main)> english.translate('Hello World')
=> "Hello World"
irb(main)> russian.translate('Hello World')
=> "Привет Мир"
irb(main)> spanish.translate('Hello World')
=> "Hola Mundo"
irb(main)> chinese.translate('Hello World')
=> "你好世界"

Using description context:

irb(main)> russian.translate('Invite', 'An invitation')
=> "Приглашение"
irb(main)> russian.translate('Invite', 'An action to invite')
=> "Пригласить"

Numeric rules with piped tokens:

irb(main)> english.translate('You have {count||message}.', :count => 1)
=> "You have 1 message."
irb(main)> english.translate('You have {count||message}.', :count => 2)
=> "You have 2 messages."

irb(main)> russian.translate('You have {count||message}.', :count => 1)
=> "У вас есть 1 сообщение."
irb(main)> russian.translate('You have {count||message}.', :count => 2)
=> "У вас есть 2 сообщения."
irb(main)> russian.translate('You have {count||message}.', :count => 5)
=> "У вас есть 5 сообщений."

Gender rules:

irb(main)> user = {:gender => :female, :name => "Anna"}
irb(main)> english.translate('{user} updated {user| his, her} profile.', :user => {:object => user, :attribute => :name})
=> "Anna updated her profile."

irb(main)> russian.translate('{user} updated {user| his, her} profile.', :user => {:object => user, :attribute => :name})
=> "Anna обновила свой профиль."

irb(main)> user = {:gender => :male, :name => "Michael"}
irb(main)> english.translate('{user} updated {user| his, her} profile.', :user => {:object => user, :attribute => :name})
=> "Michael updated his profile."

irb(main)> russian.translate('{user} updated {user| his, her} profile.', :user => {:object => user, :attribute => :name})
=> "Michael обновил свой профиль."

Gender rules with language cases:

irb(main)> actor = {:gender => :female, :name => "Анна"}
irb(main)> target = {:gender => :male, :name => "Михаил"}
irb(main)> russian.translate('{actor} sent {target} a gift.', :actor => {:object => actor, :attribute => :name}, :target => {:object => target, :attribute => :name})
=> "Анна послала подарок Михаилу."
irb(main)> russian.translate('{actor} sent {target} a gift.', :actor => {:object => target, :attribute => :name}, :target => {:object => actor, :attribute => :name})
=> "Михаил послал подарок Анне."

Decoration tokens:

irb(main)> english.translate("[bold: This text] should be bold", :bold => lambda{|text| "<strong>#{text}</strong>"})
=> "<strong>This text</strong> should be bold"
irb(main)> russian.translate("[bold: This text] should be bold", :bold => lambda{|text| "<strong>#{text}</strong>"})
=> "<strong>Этот текст</strong> должны быть жирным"

Nested decoration tokens:

irb(main)> english.translate("[bold: Bold text [italic: with italic text]] together", :bold => "<b>{$0}</b>", :italic => "<i>{$0}</i>")
=> "<b>Bold text <i>with italic text</i></b> together"
irb(main)> russian.translate("[bold: Bold text [italic: with italic text]] together", :bold => "<b>{$0}</b>", :italic => "<i>{$0}</i>")
=> "<b>Жирный текст <i>с курсив</i></b> вместе"

Data tokens with decoration tokens together:

irb(main)> user = {:gender => :male, :name => "Michael"}
irb(main)> english.translate("[bold: {user}] received [link: [bold: {count}] {count|message}]", :user => {:object => user, :attribute => :name}, :bold => "<b>{$0}</b>", :count => 5, :link => "<a href='url'>{$0}</a>")
=> "<b>Michael</b> received <a href='url'><b>5</b> messages</a>"
irb(main)> russian.translate("[bold: {user}] received [link: [bold: {count}] {count|message}]", :user => {:object => user, :attribute => :name}, :bold => "<b>{$0}</b>", :count => 5, :link => "<a href='url'>{$0}</a>")
=> "<b>Michael</b> получил <a href='url'><b>5</b> сообщений</a>"

PS. The Russian translation on tr8nhub.com could either be provided by a set of 6-9 simple translations for genders(male, female, unknown) * countfew, many or by a single advanced translation in the form of:

[bold: {user}] {user| male: получил, female: получила} [link: [bold: {count}] {count| one: сообщение, few: сообщения, other: сообщений}]

Or in a simpler form:

[bold: {user}] {user| получил, получила} [link: [bold: {count}] {count| сообщение, сообщения, сообщений}]

One of the advantages of using TML is the ability to easily switch token values. The above example in a text based email can reuse translations:

irb(main)> english.translate("[bold: {user}] received [link: [bold: {count}] {count|message}]", :user => {:object => user, :attribute => :name}, :count => 1, :bold => "{$0}", :link => "{$0}")
=> "Michael received 1 message"

irb(main)> russian.translate("[bold: {user}] received [link: [bold: {count}] {count|message}]", :user => {:object => user, :attribute => :name}, :count => 1, :bold => "{$0}", :link => "{$0}")
=> "Michael получил 1 сообщение"

You should also notice that all of the translation keys you've been using in your experiments will be registered under your application by the tr8nhub service. You can view them all at:

https://tr8nhub.com/tr8n/app/phrases

If any translation key you've tried to translate was missing a translation, you can manually translate it using the service (with the help of a machine translation suggestion).

irb(main)> russian.translate('This is a new phrase without translations')
=> "This is a new phrase without translations"

Then without leaving your IRB session, you can call the following method to reset your application cache:

irb(main)> app.reset_translation_cache

Then you can just rerun the translation method with the missing translation and you should get back the translated value.

irb(main)> russian.translate('This is a new phrase without translations')
=> "Это новая фраза без перевода"
