WordPress Core Autoloader for Composer

This is a custom autoloader generator and class map loader Composer plugin for WordPress Core.

It diverges from the default Composer autoloader setup in the following ways:

• The generated autoloader is compatible with PHP 5.2. Classes containing PHP 5.3+ code will be skipped and throw warnings.
• The paths to the classes are relative to a set constant. The default constant being used is ABSPATH.
• The class maps can optionally be configured to be case-insensitive.

Usage

In your project's composer.json, add the following lines:

{
    "require": {
        "schlessera/composer-wp-autoload": "^1"
    },
    "scripts": {
        "post-install-cmd": [
            "WordPress\\ComposerAutoload\\Generator::dump"
        ],
        "post-update-cmd": [
            "WordPress\\ComposerAutoload\\Generator::dump"
        ],
        "post-autoload-dump": [
            "WordPress\\ComposerAutoload\\Generator::dump"
        ]
    },
    "extra": {
        "wordpress-autoloader": {
            "class-root": "ABSPATH",
            "case-sensitive": true
        },
    }
}

After the next update/install, you will have a vendor/autoload_wordpress.php file, that you can simply include and use to autoload classes within WordPress Core.

Valid "extra" Keys

You can configure the autoloader by providing "extra" keys under the "wordpress-autoloader" root key.

• "class-root" :

  String value that is used to replace the dirname($vendorDir) string. The default is "ABSPATH", to make the autoloader use the ABSPATH constant.

• "case-sensitive":

  Boolean value to configure whether the classmap loader should be case-sensitive or not. The default value is true.
