I18n::Callbacks

Wrap your I18n.t calls in before and/or after hooks.

This gem provides the I18n::Backend::Callbacks backend.

You pass it an I18n backend to call plus before/after callbacks to pre-/post- process the calls.

Add this line to your application's Gemfile:

gem 'i18n-callbacks'

And then execute:

$ bundle

Or install it yourself as:

$ gem install i18n-callbacks

Supply either a :before or :after proc to the constructor, process I18n.t calls.

• :before - takes 3 parameters: locale, key and options,
• :after - takes 4 parameters: locale, key and options, and the result of the call to the backend that you are wrapping.

Suppose you want all translated strings to be prefixed by the key used to access them:

require "i18n"
require "i18n/callbacks"

wrapped = I18n::Backend::Simple.new

# ...load your translations (normally from YAML files)
wrapped.store_translations(:en, {foo: "bar"})

I18n.backend = I18n::Backend::Callbacks.new(
  wrapped,
  after: ->(locale, key, options={}, result) { "#{key}: #{result}" }
)

I18n.t(:foo) # => "foo: bar"
