I've been running through the docs and couldn't find where to init twig/intl-extra
The twig doc here says to either use use Twig\Extra\Intl\IntlExtension; or to add the extension explicitly on the Twig environment
$twig = new \Twig\Environment(...);
$twig->addExtension(new IntlExtension());
I would like tpo use the second case and add explicitly to the twig environment.
In which file should I do it?
When using twig with Symfony, you should register the extension as a service in your services.yaml file.
If installed using the twig/extensions flex recipe, it will provide the config/packages/twig_extensions.yaml file, you just have to uncomment the desired extensions (see the original comment on github).
The default configuration for reference:
services:
_defaults:
public: false
autowire: true
autoconfigure: true
# Uncomment any lines below to activate that Twig extension
#Twig\Extensions\ArrayExtension: null
#Twig\Extensions\DateExtension: null
#Twig\Extensions\IntlExtension: null
#Twig\Extensions\TextExtension: null
