Enhancement : Hooking into command palette commands

[Vrishabhsk]

What?

• Allows plugin to execute custom functionality before and after command palette command execution

Why?

• Allow hooking into command palette commands and command loaders #58200

How?

• Create two doAction calls : commands.beforeCommandExecution & commands.afterCommandExecution
• When these actions are hooked into, they receive the command executed as an argument in the callback

Testing Instructions

1. Use the following snippet in a demo plugin to execute custom functionality

import { addAction } from "@wordpress/hooks";

addAction(
	"commands.beforeCommandExecution",
	"demo",
	(command) => {
		console.log(command);
	}
);

addAction(
	"commands.afterCommandExecution",
	"demo",
	(command) => {
		console.log(command);
	}
);
