const through      = require('through2');

function logClasses() {
	let PLUGIN_NAME = 'logClasses';

	return through.obj(function (file, enc, cb) {
		if (!file.contents.length) {
			this.push(null);
			cb(console.log(` ⚠ ${PLUGIN_NAME}: The file is empty `));
			return;
		}

		try {
			// the file has a custom value "classList"
			console.log(file.classList);
		} catch (err) {
			cb(console.log(` ⚠ ${PLUGIN_NAME}: Something went wrong: `, err));
