This is a Composer Installer for WordPress MU Plugins.

The Installer is basically based on/compatible with [A Multi-Framework Composer Library Installer](https://github.com/composer/installers)but it also **supports the loader script installation** of your MU plugin.

The loader script is installed into `mu-plugins` directory by default so that you can provide your MU plugin including sub directory as a Composer package.

Example
-------

[](#example)

A package:

- *your-package-root*

    - mu-plugins/ (loader directory: `mu-plugins` by default)

        - your-plugin.php (loader script: same as your package name by default)
    - foo/

        - bar.php
    - baz.php

will be installed as:

- wp-content/mu-plugins/

    - your-plugin.php (**loader script**)
    - *your-plugin*/ (same as your package name by default)

        - mu-plugins/ (original loader directory remains)

            - your-plugin.php (original loader script remains)
        - foo/

            - bar.php
        - baz.php

Example `composer.json` File (for MU plugin package)
----------------------------------------------------

[](#example-composerjson-file-for-mu-plugin-package)

`composer.json` becomes almost the same as [A Multi-Framework Composer Library Installer](https://github.com/composer/installers)'s.

### Package Type and Dependency (`type` and `require`)

[](#package-type-and-dependency-type-and-require)

```
{
    "name": "you/your-plugin-name",
    "type": "devaloka-muplugin",
    "require": {
        "devaloka/mu-plugin-installer": "~0.2.0"
    }
}
```

### Custom Loader File (`installer-loader`)

[](#custom-loader-file-installer-loader)

`installer-loader` key is available for your custom loader file, which is the relative path from your package root.

```
{
    "extra": {
        "installer-loader": "loader/your-loader.php"
    }
}
```

You can check out a real world [composer.json](https://github.com/devaloka/devaloka/blob/master/composer.json) example.

Example `composer.json` File (for root package)
-----------------------------------------------

[](#example-composerjson-file-for-root-package)

The root package means your project's `composer.json`.

### Custom Loader Path (`installer-loader-paths`)

[](#custom-loader-path-installer-loader-paths)

`installer-loader-paths` key is available for your custom install path for loader(s).

This is almost the same as as [A Multi-Framework Composer Library Installer](https://github.com/composer/installers)'s `installer-paths`but it is for the loader file.

```
{
    "extra": {
        "installer-loader-paths": {
            "your-custom-path/{$name}/": ["vendor/package"]
        }
    }
}
```

With a `type:` prefix:

```
{
    "extra": {
        "installer-loader-paths": {
            "your-custom-path/{$name}/": ["type:devaloka-muplugin"]
        }
    }
}
```

`{$vendor}`, `{$name}` and `{$type}` variables are available.

In addition, `{$loader}` variable is available, which is the relative path to the loader file.
