Omfg. Please, Ondřej, merge this. This is 4th in a week.

[ondrejmirtes]

Wake up. It doesn't make sense and doesn't solve any problem.

[TomasVotruba]

It actually blocks the install

[ondrejmirtes]

Some time ago I split the source code in phpstan/phpstan into phpstan/phpstan-src. phpstan-src isn't a published Packagist package. That's why it doesn't have to support Symfony 5 here. It might make sense to help me upgrade to Symfony 5 to improve the contributor experience of PHPStan itself, but not for its users. That's not a pressing issue and I guess not a goal of this PR.

When PHPStan 0.12 is released in a week, phpstan/phpstan won't depend on Symfony at all, there will be no conflict. Until then, if you want to use Symfony 5, you can use phpstan/phpstan-shim.

Don't force me to merge something that doesn't make any, even marginal, technical sense. You're just behind the current developer status of the repository.

[pepakriz]

Any reason why not to merge it to the 0.11.x branch? Because in our project we currently can't use shim version (a lot of customizations...)

[ondrejmirtes]

@pepakriz If you can't use the shim version now, you won't be able to use PHPStan 0.12 at all. Please tell me what's blocking you and I'll try to look into it.

[pepakriz]

@ondrejmirtes 0.12 is not released yet and the current master branch is very unstable (tested a week ago). I know we should switch to shim, but it takes some time and Symfony 5 is already released and we'd like to use it.

[TomasVotruba]

Shim doesn't help. Same phpstan command that worked before now fails:

[ondrejmirtes]

Yes, if you have custom compiler extensions, you're not compatible with phpstan-shim and you're not going to be compatible with PHPStan 0.12. Since compiler extensions are only for some syntax sugar inside configuration files, you can always live without them.

I need help testing this from you guys, I'm surprised you're finding about this now.

[ondrejmirtes]

You need to get rid of the DecoratorExtension here: https://github.com/Symplify/PHPStanExtensions/blob/master/config/config.neon

[ondrejmirtes]

If I understand its usage correctly, it's breaking conditionalTags section that some PHPStan extensions use. The phpstan.rules.rule tag shouldn't always be applied.

[ondrejmirtes]

@TomasVotruba Also I realized you're not able to use custom errors formatters with phpstan-shim which is something I'll fix before 0.12.
