Patch file to run after PHP Scoper to ensure the Composer Autoload namespace is prefixed

prefix-composer-autoloader-namespace.php

<?php
/**
 * Make sure the Composer\Autoload namespace is prefixed.
 * Needs to be run after php-scoper.
 *
 * `php ./patch-scoper-autoloader-namespace.php MY_PREFIX`
 */

if ( empty( $argv[1] ) ) {
	return;
}

$prefix      = $argv[1];
$scoper_path = './build/vendor/composer';

prefix_namespace_in_autoloader_file( $scoper_path . '/autoload_static.php', $prefix );
prefix_namespace_in_autoloader_file( $scoper_path . '/autoload_real.php', $prefix );
prefix_namespace_in_autoloader_file( $scoper_path . '/ClassLoader.php', $prefix );

function prefix_namespace_in_autoloader_file( $file, $prefix ) {
	$path     = $file;
	$contents = file_get_contents( $path );
	$contents = str_replace( 'Composer\Autoload', $prefix . '\Composer\Autoload', $contents );
	file_put_contents( $path, $contents );
}

Hi there, this looks like I'll need it! Came here from the php-scoper issue: humbug/php-scoper#355 (comment)

Do you have a public plugin somewhere where I could see everything you do to scope it in one package? This would be much appreciated.
