[RFC] include a new dev dependency twig-cs-fixer in the codebase

[94noni]

Description

Hello

May I propose to add the tool twig-cs-fixer (repo) in this repo as a dev dependency

RFC

What?

• this tool is like the php-cs-fixer, but for twig files
• it is based on official twig coding standard, and allows to lint, and also fix, your twig files

Why?

• it is listed on twig official documentation
• it is solid and working great
• it adds value as code standard, as per all other cs fixers

How?

• We can add it, starting from 7.2, make it run on symfony/symfony twig files present in the codebase

Thank you!

... only on the website (for now) :)

Regarding the suggestion, did you run it on the Symfony codebase ? Does it change a lot of files ? Only in "test / fixtures" or in Resources also ?

That'd be nice to know the "impact" i think :)

I didn't run it everywhere but I already found some issues like #54051

None of the tools we use (PHPUnit, PHP-CS-Fixer, Psalm) is an actual dev dependency on this repo. I don't think we want to change that.

[94noni]

actual dev dependency on this repo

yes I perhaps miswrite my purpose, more like adding a twig-cs-fix config file in the repo as its done for the php-cs-fixer
and from time to time, run it or via CI

did you run it on the Symfony codebase ?

nope, but I can of course and report back here when I 've done it

[94noni]

with a default config file, and the latest version of the fixer
on symfony/symfony 7.1, only src/Bundles
94noni@5f57bab

looks like major things are spacing inside arrays and around operators

[chalasr]

Should it be fabbot's responsibility?

[smnandre]

@chalasr If so, it should probably be Symfony specific then (at least at first) ?

[chalasr]

@smnandre Perhaps yes, I don't know much about fabbot internals as it's not public code yet. I'd expect it to run tools like php-cs-fixer only if a matching config file exists in the project. I may be wrong though.
What I'm pretty sure is, if we check twig files as part of the CI, only the files that changed in the given PR/commit should be checked (which is how fabbot operates).
