-- To use a delimiter other than a comma:
--      Just change all the occurrences of ',' to the new delimiter

// When coding plugins that rely on another one, like Private Content for bbPress or Visual Attributes for WooCommerce, you need to make if the WordPress Plugin is active to initialize your plugin routines or display a notice saying that the required plugin must be activated. In this tutorial we’ll see how to detect whether a certain plugin is active in a couple of ways.

## 1. Check whether a certain class or function or constant exists

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.
