A composer installer for installing CakePHP 3.0+ plugins.

This installer ensures your application is aware of CakePHP plugins installed by composer in vendor/.

Usage

Your CakePHP application should already depend on cakephp/plugin-installer, if not in your CakePHP application run:

composer require cakephp/plugin-installer:*

Your plugins themselves do not need to require cakephp/plugin-installer. They only need to specify the type in their composer config:

"type": "cakephp-plugin"

Multiple Plugin Paths

If your application uses multiple plugin paths. In addition to configuring your application settings you will also need to update your composer.json to ensure the generated cakephp-plugins.php file is correct:

// Define the list of plugin-paths your application uses.
"extra": {
    "plugin-paths": ["plugins", "extra_plugins"]
}

Plugin Setup

For the installer to work properly ensure that your plugin's composer config file has a proper autoload section. Assuming your plugin's namespace is "MyPlugin" the autoload section would be like:

"autoload": {
    "psr-4": {
        "MyPlugin\\": "src"
    }
}

Not strictly necessary for the working of the installer but ideally you would also have an "autoload-dev" section for loading test files:

"autoload": {
    "psr-4": {
        "MyPlugin\\": "src"
    }
},
"autoload-dev": {
    "psr-4": {
        "MyPlugin\\Test\\": "tests",
        "Cake\\Test\\" : "vendor/cakephp/cakephp/test"
    }
}

If your top level namespace is a vendor name then your namespace to path mapping would be like:

"autoload": {
    "psr-4": {
        "MyVendor\\MyPlugin\\": "src"
    }
},
"autoload-dev": {
    "psr-4": {
        "MyVendor\\MyPlugin\\Test\\": "tests",
        "Cake\\Test\\" : "vendor/cakephp/cakephp/test"
    }
}
