README

Adds to Composer, PHP's dependency manager, the ability to plug and play packages without necessarily installing a new dependency on composer.json.

Installation

Composer Plug and Play requires Composer 2.3.0 or newer.

composer require dex/composer-plug-and-play

Global installation

You can install Composer Plug and Play globally to use its abilities in all your local projects.

composer global require dex/composer-plug-and-play

Usage

Initialize a plug and play structure:

composer plug-and-play:init

Create or clone a Composer package into packages/<vendor>/<package> folder and run:

composer plug-and-play

Additional configuration

You can add some additional configuration in packages/composer.json to add more data in the final resolution of the composer.json file.

Commands

All commands use the plug-and-play.json and plug-and-play.lock files as source to project dependencies instead of composer.json and composer.lock original files.

You can use composer pp and composer pp:* as alias for all commands.

plug-and-play: installs plug and play dependencies together project dependencies.
plug-and-play:add: require a package into packages/composer.json.
plug-and-play:dump: same that composer dump-autoload, but using plug-and-play files.
plug-and-play:init: initialize plug and play plugin.
plug-and-play:install: same that composer install, but using plug-and-play files.
plug-and-play:reset: remove plug-and-play files.
plug-and-play:run: same that composer run-script, but using plug-and-play files.
plug-and-play:update: same that composer update, but using plug-and-play files.

Directories and files

Composer Plug and Play plugin needs a packages folder in the project root directory where the plug and play structure will live.

The plug-and-play.json and plug-and-play.lock files will contain the real project dependencies and plug and play dependencies.

Your project directory will look like this:

|- packages 
|  |- <vendor-name>
|  |  |- <plug-and-play-package>
|  |     |- composer.json
|  |     |- composer.lock
|  |- composer.json
|  |- plug-and-play.json
|  |- plug-and-play.lock
|
|- vendor
|  |- <vendor-name>
|     |- <require-package>
|        |- composer.json
|        |- composer.lock
|
|- composer.json
|- composer.lock

Ignore plugged packages

Sometimes you may need to ignore a package that is under development, for that adds in packages/composer.json something like this and run composer plug-and-play.

{
    "extra": {
        "composer-plug-and-play": {
            "ignore": [
                "dex/fake"
            ]
        }
    }
}

Require dev dependencies from plugged packages

When developing some package or library you may need to require its dev dependencies, for that adds in packages/composer.json something like this and run composer plug-and-play that the require-dev dependencies will be installed.

{
    "extra": {
        "composer-plug-and-play": {
            "require-dev": [
                "dex/fake"
            ]
        }
    }
}

Autoload (strategy)

You may have some problems with symlinks and recursion when developing packages inside another application or package, for that, you can use experimental:autoload strategy.

This strategy will create a simple copy of your composer.json in packages/vendor directory to do a symlink from your original vendor directory.

To activate it, you should change your packages/composer.json.

{
    "extra": {
        "composer-plug-and-play": {
            "autoload-dev": ["dex/fake"],
            "require-dev": ["dex/fake"],
            "strategy": "experimental:autoload"
        }
    }
}

You must add to autoload-dev the packages that you want to map its autoload and add to require-dev the packages that you want to require its dev dependencies.
