The filter "truncate" (of twig) does not exist in a view of a vendor bundle

Question

I am trying to use the bundle JMS Translation but I have this error. It is I guess because my version of twig is not the same the one of the bundle? What to do?

CRITICAL - Uncaught PHP Exception Twig_Error_Syntax: "The filter "truncate" does not exist in "...\vendor\jms\translation-bundle\JMS\TranslationBundle/Resources/views/Translate/messages.html.twig" at line 14" at ...\vendor\twig\twig\lib\Twig\ExpressionParser.php line 588 

Here is my requirement in composer.json:

 "require": {
        ...
        "twig/extensions": "~1.2.0",

Here is what is in the composer of JMS Translation:

"conflict": {
    "twig/twig": "1.10.2"
},
"require-dev": {
    "symfony/twig-bundle": "*",

Thanks in advance!

Answer 1

Save this in a txt file and use ever!

For Twig extensions (truncate & wordwrap)

composer require twig/extensions

after that you have two ways...

$twig->addExtension(new Twig_Extensions_Extension_Text());

Or include in services.yml

services:
    twig.extension.text:
            class: Twig_Extensions_Extension_Text
            tags:
                - { name: twig.extension }

For Symfony 4

in the file 'config/packages/twig_extensions.yaml'

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

Answer 2

Although when I had installed it, it worked fine, now, it needs this:

services:
    twig.extension.text:
           class: Twig_Extensions_Extension_Text
           tags:
               - { name: twig.extension }

With symfony 4 you can use twig extra https://twig.symfony.com/doc/2.x/filters/u.html
