A simple CLI tool to generate exclusion rules for PHP-Scoper.

You put in any PHP file and get out a several PHP files that contain a list of fully-namespaced:

• class names
• interface names
• trait names
• function names
• constant names

Example:

Let's assume you have the following stub file:

namespace WP_CLI
{
    
    trait FooTrait
    {
    
    }
    
    class Autoloader
    {
        
        public function foo()
        {
        }
        
    }
    
    function foo_func()
    {
    }
    
    define('FOO', 'BAR');
    
    const BAZ = 'BIZ';
}

namespace WP_CLI\Utils
{
    
    function wp_not_installed()
    {
    }
    
    const BAM = 'boom';
}

namespace WP_CLI\Bootstrap
{
    
    interface BootstrapInterface
    {
    
    }
    
    trait BarTrait
    {
    
    }
    
    abstract class AutoloaderStep
    {
    
    }
}

The generated exclusion lists would be:

// exclude-wp-cli-classes.php
<?php return array (
  0 => 'WP_CLI\\Autoloader',
  1 => 'WP_CLI\\Bootstrap\\AutoloaderStep',
);

// exclude-wp-cli-functions.php
<?php return array (
  0 => 'WP_CLI\\foo_func',
  1 => 'WP_CLI\\Utils\\wp_not_installed',
);

// exclude-wp-cli-constants.php
<?php return array (
  0 => 'FOO',
  1 => 'WP_CLI\\BAZ',
  2 => 'WP_CLI\\Utils\\BAM',
);

// exclude-wp-cli-interfaces.php
<?php return array (
  0 => 'WP_CLI\\Bootstrap\\BootstrapInterface',
);

// exclude-wp-cli-interfaces.php
<?php return array (
  0 => 'WP_CLI\\FooTrait',
  1 => 'WP_CLI\\Bootstrap\\BarTrait',
);

After generating your necessary files you can use them in combination with php-scopers excluded-symbols feature.

We already generated exclusion lists for WordPress, WP-CLI and WooCommerce. You can find them here:

• sniccowp/php-scoper-wordpress-excludes
• sniccowp/php-scoper-wp-cli-excludes
• sniccowp/php-scoper-woocommerce-excludes

These are automatically generated using the published stubs from: https://github.com/php-stubs

It's however not a requirement to use stubs files. Any PHP code will work.

Using

Installation

composer/require sniccowp/php-scoper-excludes --dev

Create a configuration

Generates a configuration file in the current working directory:

vendor/bin/generate-excludes generate-config

// generate-excludes.inc.php
return [
    Option::EMULATE_PHP_VERSION => Option::PHP_8_0,
    Option::OUTPUT_DIR => __DIR__.'/excludes',
    Option::FILES => [
    
        Finder::create()->files()
              ->in(__DIR__.'/vendor/php-stubs')
              ->depth('< 3')
              ->name('*.php'),
              
              __DIR__.'/foo.php',
              
              [__DIR__.'/bar.php', __DIR__.'/baz.php']
    ],
];

Using symfony/finder is totally optional. You can also provide a list of strings or any iterable.

Generating your exclusion lists
