Gulp task that lists all gulp tasks registered (excluding built-ins 'install' and 'uninstall')

GULP-list-all-tasks-registered.js

require('colors');

gulp.task('get-tasks', () =>
    (process.nextTick(() => {
        console.log('\n_________ALL REGISTERED GULP TASKS_________');
        Object.keys(gulp.tasks).forEach((t) =>
            ((t === 'install' || t === 'uninstall') ? null :
                console.log('-- ' + t.bgBlack.green)))
        console.log('___________________________________________\n');
    })));
    
  // requires you to have done this in the project root first: 
  //        npm install colors --save-dev

A little update for gulp v4 with babel

const tasksTask = gulp =>
	process.nextTick(() => {
		console.log("┌─────────────────────────────────────────┐");
		console.log("│        ALL REGISTERED GULP TASKS        │");
		console.log("├─────────────────────────────────────────┤");
		Object.keys(gulp.registry().tasks()).forEach(t => {
			if (t !== "install" && t !== "uninstall") {
				let nameRow = "│ " + t;
				for (let i = 0; i < 40 - t.length; i++) {
					nameRow += " ";
				}
				nameRow += "│";
				console.log(nameRow);
			}
		});
		console.log("└─────────────────────────────────────────┘");
	});

export { tasksTask };
