Draft for a simple PSR providing a trivial abstraction of the local system environment.

Why? So we can stop using hacks to work around dependencies on system state - so that these dependencies can be made visible as (constructor) dependencies, and so we can mock the implementations under test.

Introduction

⚠️ I am no longer actively maintaining this. ⚠️

With the Windows 10 Creators Update comes an awesome new opportunity to run a lighweight Ubuntu Linux environment as a subsystem of Windows. This is officially known as Windows Subsystem for Linux (WSL) or Bash on Windows.

This is great news for PHP developers using Windows - we can now get access to native Linux builds of PHP, PECL extensions, ImageMagick, NGINX and other server components and tools, without having to migrate to a Linux desktop environment!

In this guide, we'll get you set up with WSL itself, a working PHP 7.2 environment with OpCache, XDebug and task/terminal integration with Php Storm, and working NGINX configuration - as well as various tools, including PEAR/PECL, Composer and Node.JS.

You can have a linear workflow with the array functions.

The following is unreadable:

$output = array_reduce(
  array_map(
    function($n) { return $n ** 2; }
    array_filter($input, function($n) { return $n % 2 == 0; })
  ),
