X3P0 Prelude
============

[](#x3p0-prelude)

A Composer script that copies vendor packages into your project and rewrites their namespaces, preventing conflicts when the same package is used across multiple projects in the same WordPress installation.

Requirements
------------

[](#requirements)

- PHP 8.1+
- Composer 2.0+

Installation
------------

[](#installation)

```
composer require-dev x3p0-dev/x3p0-prelude
```

Configuration
-------------

[](#configuration)

Add an `x3p0.prelude` block to the `extra` section of your `composer.json`, then register the script entry point:

```
{
	"scripts": {
		"post-install-cmd": [
			"@x3p0-prelude"
		],
		"post-update-cmd": [
			"@x3p0-prelude"
		],
		"x3p0-prelude": "X3P0\\Prelude\\Compose::run"
	},
	"extra": {
		"x3p0": {
			"prelude": {
				"prefix": "MyProject\\Vendor",
				"output-path": "packages",
				"packages": {
					"vendor/package-name": {
						"replace": "OriginalNamespace\\"
					}
				}
			}
		}
	}
}
```

### Options

[](#options)

KeyRequiredDescription`prefix`YesThe namespace prefix to apply to all copied packages.`output-path`YesDirectory to copy packages into, relative to your project root.`packages`YesMap of packages to copy, keyed by `vendor/package` path.### Package options

[](#package-options)

Each entry under `packages` is keyed by the `vendor/package` path as it appears in your `vendor/` directory. Glob-style wildcards are supported.

KeyRequiredDescription`replace`NoThe original namespace root to rewrite. If omitted, files are copied without modification.### Wildcards

[](#wildcards)

Use `*` within a package key to match multiple packages under a vendor:

```
"packages": {
	"some-vendor/*": {
		"replace": "SomeVendor\\"
	}
}
```

Use `"*"` alone to match all remaining packages in `vendor/`:

```
"packages": {
	"my-vendor/specific-package": {
		"replace": "SpecificNS\\"
	},
	"*": {}
}
```

How it works
------------

[](#how-it-works)

When the script runs, it:

1. Clears the output directory.
2. Copies each configured package from `vendor/` into the output directory.
3. Rewrites every occurrence of the original namespace root in copied PHP files, prepending your `prefix`.

For example, with `prefix` set to `MyProject` and `replace` set to `X3P0\\`, a copied file containing `X3P0\Framework\Container` becomes `MyProject\Framework\Container`.

Autoloading the output
----------------------

[](#autoloading-the-output)

Register the copied packages in your `autoload` block. The exact approach depends on the package structure; a classmap is the simplest option:

```
"autoload": {
	"classmap": ["packages/"]
}
```

Or use PSR-4 if the package has a known `src/` layout:

```
"autoload": {
	"psr-4": {
		"MyProject\\Framework\\": "packages/vendor/package/src/"
	}
}
```

License
-------

GPL-3.0-or-later.
