targeting the current version of PHP that's running vs basing it off of composer.json's "php": ">=5.0.0"

Here's my rector.php file:

<?php

use Rector\Config\RectorConfig;
use Rector\PHPUnit\Set\PHPUnitSetList;

return RectorConfig::configure()
    ->withPaths([
        __DIR__ . '/tests',
    ])
    ->withSets([
        PHPUnitSetList::PHPUNIT_80,
    ]);

I additionally have this in my composer.json:

    "require": {
        "php": ">=5.0.0"
    },

When I run vendor/bin/rector process --dry-run with all that the AddReturnTypeDeclarationRector rule is not applied. If, however, I remove the "php": ">=5.0.0" bit, the AddReturnTypeDeclarationRector rule is applied.

I want the rule to be applied but don't want to remove the "php": ">=5.0.0" bit. How might I do this?

I guess I could add ->withPhpVersion(PhpVersion::PHP_80) to my rector.php, however, I'm testing my script via GitHub Actions across a gamut of different PHP versions (7.4 - 8.5) and I only have one rector.php, so if I do ->withPhpVersion(PhpVersion::PHP_80) it'll do that for PHP 7.4 and PHP 8.5 as tho even tho I don't want it too.

If it weren't for the "php": ">=5.0.0" bit it seems like rector targets the version of PHP that rector is running on. Is there a way to tell rector to do that even with the "php": ">=5.0.0" bit?

You can add if else based on environment, eg: on github vs local in rector.php so the set php version will adapt based on target php version.

$rectorConfig = RectorConfig::configure()
    ->withPaths([
        __DIR__ . '/tests',
    ])
    ->withSets([
        PHPUnitSetList::PHPUNIT_80,
    ]);

if (getenv("some_env")) {
    $rectorConfig = $rectorConfig->withPhpVersion(80000);
}

return $rectorConfig;
