How to prevent this PHP8 error on PHP7.4 systems?

[bernhard]

The latest version of RockMigrations (and many other of my modules) require PHP8.0 as minimum version. PHP7.4 is end of life, so everybody should update anyhow. But I'd be interested if there is a better solution to the following problem:

When on a PHP7.4 system and you install (or try to install) RockMigrations you'll end up with an error like this:

The module has PHP>=8.0 in its requires array, but it can not check for that dependency because PHP complains before even executing the check.

That means the modules backend is unusable until you remove the module manually and/or update your PHP version.

Any ideas?

How about writing your ternary like this?

title: ($d->title ? $d->title : $name),

That's what ModuleName.info.php was designed for. PW can check dependencies without loading the full module.

Thx @Rudy but the error comes from the first colon that comes from PHP8's named arguments

Ah! Thx about that reminder. I got used to writing everything into the .module.php file as I saw no benefit in having a separate file, but that totally makes sense ? Thx!
