Possible improvements

• Read the composer.json file and highlight entries not in the current file
• Highlight when a different version is available (from what is in composer.json file)
• Report only version numbers compatible with current composer.json file (hard!)

Hi Alan

Thanks for this small script.

But you should re-order your paths where your script searches for the auth.json file, the $home . '/.composer/auth.json' should be the last place to search.

For example, I have a global auth.json file for my user in ~/.composer/auth.json but this only contains my github credentials, not the credentials for my Magento 2 projects, as I use an auth.json file per project inside the root of that project.
So your current script would fail to find the correct credentials in this case.

I would suggest you change the order to:

    $paths = [
        'auth.json',
        'app/etc/composer/auth.json',
        $home . '/.composer/auth.json',
    ];

I'm not sure about the app/etc/composer/auth.json file, I've never seen that before, can you shed some light on in what circumstances this file can be used?

Thanks!

For future searchers, this information can now be found within the My Purchases section of Magento Marketplace.

It is listed as the "Component name" in the Technical details popover that appears below the Download button for each module.
