@staabm can you maybe reset your branch off the one on my fork? This targets 2.x which would be preferable as Composer uses that still.

There are two problems:

• phpstan fails to run somehow https://github.com/composer/pcre/actions/runs/9888823477/job/27313571168?pr=25
• tests also fail https://github.com/composer/pcre/actions/runs/9888823483/job/27313570804?pr=25

I think these might just be outdated things causing problems, but I am not familiar enough to fix it so I'd appreciate if you can take a look.

I think the errors are related to the phpunit-bridge, see https://github.com/composer/pcre/pull/24/files#r1648824476

can we get rid of the bridge for composer/pcre 2.x?
I think it could in general simplify the CI setup in case we could use plain phpunit.

[Seldaek]

It now runs the phpstan tests without the bridge, so I don't think it's that.

Alright, thanks @staabm !
