E9s

Enrichments (e9s) for a pluggable CMS frontend, internationalization (i18n) and localized pluralization

Introduction

E9s was created due to the need of simply implementing I18n within a Rails application. This simplifies internationalization of your Rails application making a Rails developers life much easier. E9s is divided into modules (as gem and plugin): Rich-CMS , Rich-i18n and Rich-pluralization. A list of E9s’ features:

Pluggable CMS

Easy setup – Rich-CMS only has a two-liner setup
Authentication – Easily specify the authentication logic to be used
Add editable content – Easily specify content available within the CMS by registering them

I18n

Translate on-site – Just specify you want to use Rich-CMS and you are set to translate in the front-end
Localized pluralization – Translations only in singular form are sufficient enough as E9s can pluralize in foreign languages
Default values – Use the translation key (or a portion) as default value: "continue".t returns "continue" and "text.Welcome_to_our_site".t returns "Welcome to our site"
An easy interface – Just call the t method on string or symbols to translate and pl to pluralize
Combine translations – Joining keys with spaces combines translations: "More houses".t returns "Meer huizen" in Dutch
Preserve i18n meta data – Rich-i18n preserves the translation key, value, locale and derivative key (the argument passed for translation). Enquiring this can come in handy when implementing an internationalization CMS (see Rich-CMS).

Formtastic

Labels, seatholders and default values – Not only translate labels, but also hint text (so called seatholders) and even translate default values
Unobtrusive implementation – Translate labels and seatholders unobtrusively, in other words: leave your semantic_form_for (view) code completely untouched
Specific translations – Not only specify general translations for labels and seatholders, but make them model or even form specific

Inflections

Preserve character casing – E9s preserves the casing in your translations: "save".t returns "bewaar", "Save".t returns "Bewaar" and "SAVE".t returns "BEWAAR" in Dutch
Preserve pluralization – E9s singularizes or pluralizes your translations depending on the key: "house".t returns "huis" and "Houses".t returns "Huizen" in Dutch

Installation

Using E9s as gem in Rails 3

Add E9s in Gemfile as a gem dependency:

  gem "e9s"

Run the following in your console to install with Bundler:

  sudo bundle install

Using E9s as gem in Rails 2

Add E9s in environment.rb as a gem dependency:

  config.gem "e9s"

Run the following in your console:

  sudo rake gems:install

Using E9s as plugin in Rails 3

  rails plugin install git://github.com/archan937/e9s.git

Using E9s as plugin in Rails 2

  script/plugin install git://github.com/archan937/e9s.git

Testing E9s out-of-the-box

Run the Rails console:

In Rails 3

  rails c

In Rails 2

  ./script/console

Start translating in Dutch:

  >> I18n.locale = :nl
  => :nl
  >> "Male / Female".t.to_s
  => "Man / Vrouw"
  >> "MORE HOUSES".t.to_s
  => "MEER HUIZEN"

Use the provided Rails generator

In order to manage translations and/or CMS content. You need the following entities:

An Authlogic authenticated user model
An ActiveRecord model used for translation storage
An ActiveRecord model used for CMS content storage

Fortunately, E9s is provided with a Rails generator with which you can generate all the entities.

In Rails 3

Run the following in your console:

  rails g enrichments -m

Note: The generator has the -m or --migrate option which runs rake db:migrate after creating the files.

Actually, this generator calls the generators of Rich-CMS and Rich-i18n. For more information, please check the README files.

In Rails 2

Run the following in your console:

  script/generate enrichments -m

Start specifying translations

Populating config/locales

At default, I18n uses I18n::Backend::Simple of which translations are stored within YAML files located in config/locales. When adding a new language, it is adviced to copy a YAML file from http://github.com/svenfuchs/rails-i18n/tree/master/rails/locale in which you can add your translations. Of course, you can also use other I18n backends like I18n::Backend::ActiveRecord for translations stored in the database.

Words

As E9s automatically singularizes or pluralizes the translation (depending on the passed key), you only have to specify translations in singular form.

Note: specified in config/locales/nl.yml

---
nl:

  word:
    "yes":   ja
    "no":    nee
    house:   huis
    letter:  brief
    sign:    teken
    user:    gebruiker
    more:    meer

Pluralization

A very powerful feature of E9s is pluralization which resembles the inflections of ActiveSupport::Inflector. Unfortunately, specifying inflections within config/initializers/inflections.rb also influences your Rails application and thus causes great problems.

E9s provides you to specify pluralization rules for different locales. You have to use regular expressions in order to specify them.

Note: specified in config/locales/nl.yml

---
nl:

  e9s:
    singular:
      - rule:          en$
        replacement:   ""

    plural:
      - rule:          ee$
        replacement:   eeën

      - rule:          heid$
        replacement:   heden

      - rule:          (c|m|n|t)us$
        replacement:   \1i

      - rule:        | abc, acme, acne, (a|ë|i|o|u|y)$
        replacement:   \1's
        exceptions:    (ai|eau|ei|li|lieu|ooi|ou|shampoo|spray|vlo)$

      - rule:          (blad|kind)$
        replacement:   \1eren
        exceptions:    (aanrecht|advertentie)blad

      - rule:          (e|em|el|er|erd|aar|aard|um|eur|foon|oor|ier|en|ie|eau|show|festival|é)$
        replacement:   \1s

      - rule:        | (a|e|o|u)\1([^aeiou])$
        replacement:   \1\2en

      - rule:        | (aï|alia)(s),
                       ([^aeiou][aeiou])([^aeiou])$
        replacement:   \1\2\2en
        exceptions:    dal, pad, slot, vat, weg,
                       (blad|dag|dak|engel|gat|weg)$

      - rule:          f$
        replacement:   ven

      - rule:          s$
        replacement:   zen

      - rule:          $
        replacement:   en

    irregular:
      gelid:           gelederen

    uncountable:
      - geld
      - informatie
      - rijst

For a complete example, please open http://github.com/archan937/rich_pluralization/blob/master/locales/nl.yml which contains Dutch inflections.

Labels and seatholders

You can translate labels and seatholders (placeholders :D) within Formtastic forms without altering its code.

Note: specified in config/locales/nl.yml

---
nl:

  word:
    password:       wachtwoord

  label:
    user_name:      gebruikersnaam
    content:        bericht

    Question:
      content:      jouw vraag

    Answer:
      content:      jouw antwoord

    (search_form)
      criteria:     uw zoekcriteria

  seatholder:
    email_address:  [email protected]

    Question:
      content:      Hoeveel uren zitten in een dag?

    Answer:
      content:      24 uur

    (search_form)
      criteria:     '&Voorbeeld'

Start translating / pluralizing

String / Symbol methods

E9s adds the following methods to strings and symbols:

t – which translates the string or symbol
pl – which pluralizes the string or symbol with inflections of the current I18n locale

Further more, E9s has enriched the String class with other inflection methods such as upcase_first, cp_case, upcase_first! and pluralize!. Please visit http://github.com/archan937/rich_i18n/blob/master/lib/rich/i18n/core/string/inflections.rb to see all the methods.

Default values and case preservation

When not specified, E9s returns a default value based on the passed key: it splits the key on "." and (sort of) humanizes the last part. Sort of, because it actually replaces "_" with " " and it copies the casing of the key with the cp_case method of the String class.

Combined keys

You can combine translations by using passed string containing translation keys joined with spaces.

Translation meta data with EnrichedString

When translating text, you possibly want to know the key, the value, the locale and the derivative key (the argument passed for translation). Rich-i18n preserves just that in an EnrichedString which is a wrapper containing meta data and the translation. Calling .meta_data returns a hash with the meta data:

  >> "MORE".t.class
  => Rich::I18n::Core::EnrichedString
  >> "MORE".t.meta_data
  => {"value"=>"meer", "locale"=>:nl, "derivative_key"=>"MORE", "key"=>"word.more"}

Keep in mind that combined translations are possible and fortunately EnrichedString is able to cope with that. A concatenated translation has merged_strings which contains every segments:

  >> "More streets".t.to_s
  => "Meer straten"
  >> "More answers".t.merged_strings.collect(&:to_s)
  => ["Meer", " ", "antwoorden"]
  >> "More answers".t.meta_data
  => {}
  >> "More answers".t.merged_strings.first.meta_data
  => {"value"=>"meer", "locale"=>:nl, "derivative_key"=>"More", "key"=>"word.more"}
  >> "More answers".t.merged_strings.last.meta_data
  => {"value"=>"antwoord", "locale"=>:nl, "derivative_key"=>"answers", "key"=>"word.answer"}
  >> ("one".t + " " + "question".t).to_s
  => "één vraag"
  >> ("one".t + " " + "question".t).merged_strings.collect(&:to_s)
  => ["één", " ", "vraag"]

String.to_output

E9s adds the to_output method to the String class. This returns the an i18n tag with HTML 5 attributes in which the translation meta data is provided:

  >> E9s::Engine.enable_enriched_output = true
  => true
  >> "More answers".t.to_s
  => "<i18n data-value='meer' data-locale='nl' data-key='word.more' data-derivative_key='More' data-editable_input_type='' data-i18n_translation='Meer'></i18n> <i18n data-value='antwoord' data-locale='nl' data-key='word.answer' data-derivative_key='answers' data-editable_input_type='' data-i18n_translation='antwoorden'></i18n>"

This can be very handy when implementing a CMS in which users change translations. Please note that http://github.com/archan937/e9s-demo uses this feature to highlight translations. Later on this will also be used in Rich-CMS, a gem / plugin that makes inplace translating possible (please be patient for this to be released).

I18n examples

As a result of the YAML file specified above, you will get the following translations in your Rails console:

  >> "word.house".t.to_s
  => "huis"
  >> "word.Event".t.to_s
  => "Event"
  >> "LETTERS".t.to_s
  => "BRIEVEN"
  >> "application.index.Welcome_to_our_site".t.to_s
  => "Welcome to our site"
  >> "word.users".t.to_s
  => "gebruikers"
  >> "Signs".t.to_s
  => "Tekens"
  >> "MORE USERS".t.to_s
  => "MEER GEBRUIKERS"
  >> "More houses".t.to_s
  => "Meer huizen"

Render E9s in your views

Alter your layout

Add the following line at the beginning of the <body> tag:

  <body>
    <%= e9s %>
    ...
  </body>

Render CMS content

The E9s module Rich-CMS requires a rendered DOM element provided with meta data of the content instance. Fortunately, you can call a method provided by Rich-CMS. Just specify the identifier of the content type and the key of the CMS content instance in question:

  >> key = "test_content"
  => "test_content"
  >> Rich::Cms::Engine.to_content_tag(".cms_content", key)
  => "<div class='cms_content' data-key='test_content' data-value='Hello world!'>Hello world!</div>"

When using a combined key for content identification, just call it as follows:

  >> Rich::Cms::Engine.to_content_tag(".cms_content", {:key => key, :locale => I18n.locale})
  => "<div class='cms_content' data-key='test_content' data-locale='nl' data-value='Hallo wereld!'>Hallo wereld!</div>"

Note: In this case, the content was registered with Rich::Cms::Engine.register(".cms_content", {:class_name => "Cms::StaticContent", :key => [:key, :locale]})

We have also provided you a helper method to render Rich-CMS content tags:

  ...
  <%= rich_cms_tag ".cms_content", "test_content" %>
  <%= rich_cms_tag ".cms_content", {:key => "test_content", :locale => I18n.locale} %>
  ...

You can also render CMS content as HTML. When editing CMS content in Rich-CMS, a WYSIWYG editor will be displayed. Just add :as => :html.

  ...
  <%= rich_cms_tag ".cms_content", "application.index.welcome", :as => :html %>
  ...

For further documentation, please check the Rich-CMS README file.

Render translations

The E9s module Rich-i18n has its own conventions which are simpler. A few examples:

  ...
  <h1>
    <%= "application.index.Welcome_to_our_renewed_website".t %>
  </h1>
  <%= link_to "PRODUCTS".t, products_path %>
  <%= "Hello world".t %>
  ...

You can also render translations as HTML. When editing translations in Rich-CMS, a WYSIWYG editor will be displayed. Just add :as => :html.

  ...
  <%= "application.index.welcome_text".t :as => :html %>
  ...

For further documentation, please check the Rich-i18n README file.
