make DeclareStrictTypesRector skip files without namespace, as very risky in files without PSR-4 autodiscovery

[TomasVotruba]

This will improve rule usability, as will skip front-controller files, handy scripts and legacy codebases without PSR-4.
There strict types might not be a best way to apply at first. The rest of project would benefit though 👍

How can I automatically clean my files which do not have namespace to not use strict_types? Is there a rule which does that?

[TomasVotruba]

What's the goal of that?

[simeonbugarija]

You mentioned that using strict_types in files without namespace is risky.

Running and older version of this package, it added strict_types everywhere, like in config files, public/index.php, helpers etc..

Is there a way to revert that automatically or do I have to manually check all files and remove strict_types in files without namespace?

Maybe this rule should remove strict_types in files without namespace or create a new rule specifically for that purpose?

[TomasVotruba]

I see. Maybe I'm trying to be too safe here :) Have you noticed any bugs during this application?

What we can do is to have 2 rules, one for namespaced files (modern PHP 5.3+ approach) and one for non-namespaced files (configs and more free files where more vague types can appear).

Everything is working fine in my app, I did not notice any problems because of that.
