Your LimeSurvey version: 3.x latest
==================
Hello there, I'm extending PluginManager\PluginBase class. I have name, description attributes but I can't find a method or attribute to evaluate if plugin was enabled.
My plugin is doing things, whatever. Just hooking also when disabled.

Inside init() method I've just subscribed to beforeAdminMenuRender. I'd like to add a trigger who subscribe only if plugin is enabled.

I've tried with $this->checkActive(__CLASS__) but dies with  Trying to get property 'active' of non-object

Nevermind -_- I founded, inside api!

Solution is $this->api->pluginIsActive($this->getName())

… argl … it's in API …

I use own system always … (check in DB directly)

Else : currently i try to create helper for the tools
1. Yii::getPathOfAlidas : gitlab.com/SondagesPro/coreAndTools/relo...AnyResponse.php#L267
2. App()->getConfig : gitlab.com/SondagesPro/coreAndTools/relo...nyResponse.php#L1252

Oldschool singleton development sometimes can be a bit confusing. Really fast but needs a lot of discipline.

For plugin development, I better prefer using namespacing and dependency injection, but the important thing is to get things done in a safe, affordable and fast way.
