Twig: Working internationalization (i18n) example

Question

I am looking for a working i18n example for Twig (the template engine).

Documentation is a bit sparse when it comes to language files. Where should they go, how should

Answer 1

The twig i18n extension is based on gettext. So first of all everything related to gettext applies. You find that documented here: Gettext Docs.

So now to the more concrete parts of you question, but please ensure you've at least understood the basic principles with gettext:

Where should they [the language files] go

Into the directory that has been registered for the text-domain.

, how should they look and what should they be named?

Language files should be named the following:

text-domain-locale.po/mo

Example for a text domain called myAppPhp and the fr_FR locale:

myAppPhp-fr_FR.po
myAppPhp-fr_FR.mo

I have been trying with .po/.mo files, no luck.

.po/.mo sounds good to me, maybe you have just missed the path where to move them or you have forgotten to add the text-domain in front.
