Remove "final" keywords from classes and methods in vendor packages with Unfinalize

Unfinalize by Steve Bauman just released v1, and those release notes are worth a minute of your time.

Unfinalize is a package that uses PHP CS Fixer to permanently remove final keywords from composer vendor packages.

Please Note: you'll need to fork this package if you want to use it as the PHP CS Fixer team has marked the original package as a conflict. You can get around this by forking this package with a new name.

- final class Foo
+ class Foo
{
-   final public function bar()
+   public function bar()
    {
        // ...
    }
}

When you run it, it does the following:

• Updates to PHP files are done safely, quickly, and performant.
• Changes are stored permanently. There is no performance impact using Unfinalize.
• No additional dependencies to your application. Unfinalize and its dependencies are compiled into a single phar file.

#Unfinalize Usage

Install it first:

composer require stevebauman/unfinalize

Then, inside your composer.json file, add the vendor packages you want to remove the final keywords from inside:

{
    "unfinalize": [
        "vendor/package"
    ]
}

Next, add the unfinalize command to your composer.json so it runs on composer update:

{
  "scripts": {
    "post-update-cmd": [
      "@php vendor/bin/unfinalize run"
    ]
  }
}

Finally, run composer update.

#Unfinalize Options

#--mark-final

If you would like final classes and methods to be marked with a @final doc block, you may add the --mark-final option to the unfinalize command:

{
  "scripts": {
    "post-update-cmd": [
      "@php vendor/bin/unfinalize run --mark-final"
    ]
  }
}

Which will produce:

Before:

final class Foo
{
    final public function bar()
    {
        // ...
    }
}

After:

/**
 * @final
 */
class Foo
{
    /**
     * @final
     */
    public function bar()
    {
        // ...
    }
}

#--dry
