I18n lazy lookup generator (for Rails 3)

WTF lazy lookup?

• Rails has a way called "Lazy Lookup" in i18n.
• it gives us a convenient way to look up the locale inside views.

See when you have the following yaml:

es:
  books:
    index:
      title: "Foo"

You can look up the books.index.title value inside

app/views/books/index.html.erb template like this (note the dot):
<%= t '.title' %>

Also, Rails recommends to organize of locale files:

|-views
|---books
|-----es.rb
|-----en.rb
|---users
|-----es.rb
|-----en.rb
|---navigation
|-----es.rb
|-----en.rb

Usage

i18n_lazy_lookup:generate generates files with controller name

$ rails g i18n_lazy_lookup:generate
      create  config/locales/views
      create  config/locales/views/comments
      create  config/locales/views/comments/en.yml
      create  config/locales/views/comments/ja.yml
      create  config/locales/views/posts
      create  config/locales/views/posts/en.yml
      create  config/locales/views/posts/ja.yml

If file exists, it leaves.

$ r g i18n_lazy_lookup:generate
       exist  config/locales/views
       exist  config/locales/views/comments
   identical  config/locales/views/comments/en.yml
   identical  config/locales/views/comments/ja.yml
       exist  config/locales/views/posts
   identical  config/locales/views/posts/en.yml
   identical  config/locales/views/posts/ja.yml

You can specify controller and action names with i18n_lazy_lookup

$ r g i18n_lazy_lookup foo index show
   exist  config/locales/views
  create  config/locales/views/foo
  create  config/locales/views/foo/en.yml
  create  config/locales/views/foo/ja.yml

YAML will be like as below config/locales/views/foo/ja.yml

ja:
  foo:
    index:
    show:

The default locale is en, but you can overide it in config/application.rb

# Customize generators
config.generators do |g|
  g.locales %w(en ja)
end

TODO

• Create controller and scaffold hooks.
• Add spec. also fixing code as well.
• Create inheritance file. (eg: default)
