Problem

• Finding all translations by parsing is impossible for dynamic calls
• often even static calls are not found
• some file formats do not have a gettext parser

Solution

• log all translations during test execution
• write them to an parseable temp file
• use gettext:find / gettext:pack as usual
• missing translation = missing test, write tests!

This will only work with FastGettext and RSpec for now!

Install

• script/plugin install git://github.com/grosser/gettext_test_log.git
• Gem: sudo gem install grosser-gettext_test_log -s http://gems.github.com/

Usage

rake gettext:test_log

Optionally copy+modify task with options:

:exclude_msgids_in_po_files=>[
  'some_po_file_that_contains_translations_you_do_not_need.po'
]

Add to your spec_helper:

#spec/spec_helper.rb
GettextTestLog::activate_test_logging

Run:

rake gettext:test_log
rake gettext:find  #find new translations
#fill newly found translations
rake gettext:pack #write translations

Examples output

#locale/testlog_phrases.rb
_("Add to favorites")
_("Added a subtitle to %{name}")
_("Additional Information")
_("Address")
...

Unwanted translations

When using gettext_i18n_rails, most of the columns of a model will be translated during model tests this can be annoying since normally no user will see them. To disable this, add to spec/spec_helper.rb :

class ActiveRecord::Base
  def self.human_attribute_name(attr)
    attr.to_s
  end
end

TODO

• needs tests... :(
• make compatible with GetText and FastGettext at the same time ?
