Install
This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.
Install straight from GitHub with WP-CLI:
wp plugin install https://github.com/ryannutt/wordpress-whoops/archive/refs/heads/master.zipWordPress Whoops Plugin
Over the past year or so I've been doing quite a bit of development with Laravel. But I still really like WordPress. There are a couple of libraries in Laravel that I really miss though when I'm working on WordPress plugins.
The first one is the outstanding filp/whoops library. It catches exceptions and makes it much easier to figure out what's going on.
The other is the dump() and dd() methods from the syfony/var-dumper package.
With this plugin activated, both of these libraries are loaded so you can use them while developing your plugins or themes. But they're only loaded when WP_DEBUG is true.
Probably not a plugin to use on a production server.
Setup
There really isn't any. Install it into a folder in /wp-content/plugins like any other plugin (I use /wp-content/plugins/wordpress-whoops) and activate. There aren't any settings. When activated, it's working. When deactivated, it's not. You do need to set WP_DEBUG to true.
Credits
99.9% of the credit for this belongs to Filipe Dobreira for Whoops and the authors of var-dumper. The only thing I did was wrap them in about 5 lines of PHP to make it work as a WordPress plugin.
