Add drush command for generating subtheme

Hi @VladimirAus, I added a command for drush that allows you to generate subthemes with it.
Also, please add to the documentation an example of how to call this command from console.
drush --include="web/themes/contrib/bootstrap5" bootstrap5:subtheme

Not sure what is requirement of drush command because An option is available in theme for generate theme.
1. Navigate to /admin/appearance/settings/bootstrap5
2. Fill Subtheme location, Subtheme name and Subtheme machine name in the theme subtheme section and create.

This is generating a subtheme very easily and without error.

Thanks @Abyss. Good start, but command is not visible. I found few issues:

• Commands folder should be under src. Seeother modules as an example.
• Use dependency injection instead of \Drupal::.... See full phpcs log below.
• Update README.

@VladimirAus, sorry for the long answer.
In this case, we can't add dependency injection as there is a problem with it in Drupal at the moment.
Also, it doesn't make sense for us to move Commands under src, since we use autoloader to load the drush command.
You can find more detailed information here:

https://github.com/drush-ops/drush/issues/4685

Also updated the description in README.md.

I tested this and I was able to create the B5 Subtheme, I had to run this command for that

drush --include="web/themes/contrib/bootstrap5" bootstrap5:subtheme --subtheme-name="B5 subtheme"

Sadly, the drush B5 command is not available if I don't use the --include option, and I had to clear cache because the new subtheme wasn't available at /admin/appearance right after I ran the drush command.

@OPTASY, could you please describe this problem in more detail?
I made a sub theme with the command and without any additional movements after reloading the theme list page, I can see it.

Structure is not according to Drupal standard:

• Commands should be moved to src folder from Commands/bootstrap5/SubthemeCommands.php to src/Commands/SubthemeCommands.php
• namespace should be Drupal\bootstrap5\Commands instead of namespace Drush\Commands\Commands;

VladimirAus → changed the visibility of the branch 3.0.x to hidden.

Based on this Drush issue and Drush command generator I update the branch.

thanks for the patch

Merged! Thank you 🥂
