Configuration split

Config Split allows user to define a set of configuration files that get exported to a different directory from the rest of the config files. When that split is active, config files in that directory override values in the default set.

Example 1: the views_ui module should be enabled on dev environment only and aggregation should be disabled there.

1. drush cex;
2. Create a new split (admin/config/development/configuration/config-split), i.e. dev and enable it;
3. Add views_ui module to a blacklist and system.performance configuration to a greylist;
4. Change aggregation configuration;
5. drush cex.

A generator allows you to write code that uses foreach to iterate over a set of data without needing to build an array in memory, which may cause you to exceed a memory limit, or require a considerable amount of processing time to generate.

Example

<?php

/**
 * Helper function to get $count of even numbers.
 */
function func($count) {

class MyClass {
