Rails language name using I18n locale

I want to match the locale code to the specific language name. Is there any build in function in I18n/rails which would return the language name to the corresponding locales. Is installing a gem is the only way?

It seems there is no method for this in I18n. If you just need current language name, you can easily include it in corresponding locale file:

# config/locales/en.yml
en:
  language_name: "English"

And get it as usual: I18n.t('language_name') or I18n.t('language_name', locale: :en).

For general purposes you could use: https://github.com/hexorx/countries or initialize your own mapping as a ruby hash: { en: 'English', ... }.

Have a look the following post in google groups (Gist). I hope there is no default support for the required conversion in rails.

Without installing an additional gem, you could make your own key/value pairs (either store it in a json file or store it to DB) and then lookup key eg "de" and read the value (in this case, "German"). It requires a bit of manual work (or setup a rake task or something to build it for you in appropriate format from some info source) but you aren't dependent on an additional gem in that case (which, without going thoroughly through the code, might have a far greater impact on your app performance/memory wise than your custom implementation for your specific need for all you know).

I am not aware of any rails built in functions that would return the entire language name, though. You can return the language abbreviation (eg for use in html lang attribute), but I think it stops there as far as the built in functions are concerned).
