I18n Recursive Lookup

Provides a backend to the i18n gem to allow a definition to contain embedded references to other definitions by introducing the special embedded marker ${}.

All definitions are lazily evaluated on lookup, and once compiled they're written back to the translation store so that all interpolation happens once.

Example

# example.yml
foo:
    bar: boo
baz: ${foo.bar}

I18n.t(:baz) will correctly evaluate to boo.

Installation

Install the gem either by putting it in your Gemfile

gem 'i18n-recursive-lookup'

or by installing it using rubygems

gem install i18n-recursive-lookup

Add it to your existing backend by adding these lines to your config/initializers/i18n.rb (create one if one doesn't exist):

# config/initializers/i18n.rb
require 'i18n/backend/recursive_lookup'
I18n::Backend::Simple.send(:include, I18n::Backend::RecursiveLookup)

Of course you can replace the I18n::Backend::Simple with whatever backend you wish to use.

TODO

• add detection for infinite embedding cycles
