About Debug Bar Plugin Activation
From the official readme · v1.0Description
Ever been “greeted” when you activated a plugin with the dreaded:
This plugin generated # characters of unexpected output during activation….
And wondered what the unexpected output was ?
Or wondered whether a de-activation or uninstall routine was free of typical PHP errors ?
Well, no need to wonder anymore, as you can now see the output within your favorite debugging tool – the Debug Bar.
Debug Bar Plugin Activation adds a new panel to the Debug Bar which displays the output generated during plugin activation, deactivation and uninstall.
Once you’ve fixed the issues, you can remove the logged output straight from the Debug Bar panel.
And when you uninstall a plugin, the associated logged activation and deactivation output entries will be removed automatically.
This plugin was inspired by a conversation with Mika Epstein during the contributors day at WordCamp Europe 2016.
