Automatically generate file props from path

[aschempp]

would be quite cumbersome if everyone has to do that themselve?

[fritzmg]

May be use the mime type guesser from Symfony here instead?

[aschempp]

any hint what that looks like?

[fritzmg]

You could instantiate it yourself via (new MimeTypes())->guessMimeType($path). However, the symfony/framework-bundle also registers it as the mime_types service, which allows the system to add additional guessers via the MimeTypeGuesserInterface via the AddMimeTypeGuesserPass compiler pass. This would have to be done via a helper service outside this static function.

I would like to have a separate helper method. Less magic, more expressive.

[aschempp]

but that method already is a helper method to create a FileItem?

[Toflar]

Yes but right now, null is not allowed - checks have to be applied outside of the method. You are now moving them into the factory method and there are not even nullable checks.

[Toflar]

I think we should introduce a FileItemFactory service instead which provides multiple helpers for creating a FileItem and can thus also access the Symfony MimeTypeGuesser service. Also, I would like to look into providing a helper for creating a FileItem based on a FilesystemItem from Contao's VFS.
Tagging this as enhancement for 2.1.

Closing in favor of #362.
