Module development and code questions

Drupal 7 used to have a function named "theme()" to return "themed" output: https://api.drupal.org/api/drupal/includes%21theme.inc/function/theme/7.x

I'm upgrading Notify to Drupal 9 and it leverages on Advanced Help to provide help topics. Example:

$output = theme('advanced_help_topic', [
  'module' => 'notify',
  'topic' => 'users',
]);

How to do this in Drupal 9?

I believe some HTACCESS solution might be possible, but not sure how.

I use a script that creates boilerplate drupal module.

I created a folder inside the "modules" folder to store this code, but if the generated code has any issue, my site stops working since Drupal tries to read this code and consider this as a real module.

I placed this folder in a different directory, and that solved the problem, but having it inside the modules folder itself would be more logical and easy to maintain.

Hi I've created a module with a controller but now i'm getting this message;

LogicException: The controller result claims to be providing relevant cache metadata, but leaked metadata was detected. Please ensure you are not rendering content too early. Returned object class: Drupal\Core\Cache\CacheableJsonResponse. in Drupal\Core\EventSubscriber\EarlyRenderingControllerWrapperSubscriber->wrapControllerExecutionInRenderContext() (line 154 of core\lib\Drupal\Core\EventSubscriber\EarlyRenderingControllerWrapperSubscriber.php).

Hello,

In Drupal 9 installation there is a view where nodes are listed. Now I want to do two things.

1: add a field with the path alias to the view.

2: add an exposed filter to filter path aliases.

Unfortunately I am not able to do this. The only way to add a field with path alias is the field "Link to Content", which can be output as plain text. But I cannot define an exposed filter for this field.

Hi,

I've created a tag in git 8.x-1.0 and added a release to it. Is it possible to move this tag to the latest commit of 8.x-1.x?

I've tried:

git tag --force 8.x-1.0 <latest-commit-id>
git push --force --tags

remote: The tag 8.x-1.0 is tied to a release on Drupal.org, and cannot be relocated or deleted.
remote: error: hook declined to update refs/tags/8.x-1.0
