[RFC] Swap var comment to types comment for variable type hinting

[94noni]

Hello,

small RFC regarding twig types as var typehint (https://twig.symfony.com/doc/3.x/tags/types.html)
https://speakerdeck.com/fabpot/symfonycon-vienna-2025-twig-still-relevant-in-2025?slide=25

Do you think it is worth it? and can it be feasible?
(yes still experimental but it seems to work well already)

closed, just saw #322
dont know why I does fix locally, will investigate more

edit; reopening to know if it can be replaced by this software, not just linted ?

What's the output before/after ?

[94noni]

something like that somehow:

-{# @var truck_shipper \App\Entity\TruckShipper #}
-{# @var form \Symfony\Component\Form\FormView #}
-{# @var active boolean #}
+{% types truck_shipper: 'App\Entity\TruckShipper' %}
+{% types form: 'Symfony\Component\Form\FormView' %}
+{% types active: 'boolean' %}

This is doable:

• Listen COMMENT_TEXT_TYPE https://github.com/VincentLanglet/Twig-CS-Fixer/blob/main/src/Token/Token.php#L42
• If the value is not @var return
• Else parse the whole comment, looking for COMMENT_START_TYPE before and COMMENT_END_TYPE

COMMENT_START_TYPE 
COMMENT_WHITESPACE_TYPE
COMMENT_TEXT_TYPE
COMMENT_WHITESPACE_TYPE
COMMENT_TEXT_TYPE
COMMENT_WHITESPACE_TYPE
COMMENT_TEXT_TYPE
COMMENT_WHITESPACE_TYPE
COMMENT_END_TYPE

• Rewrite it

{% types foo: 'bar' %}

where foo is the 2nd COMMENT_TEXT_TYPE and bar the third.

But I don't plan working on it. Feel free to try
