Drupal Bridge

Composer

In your composer.json, define the Drupal root relative to the composer.json file. drupal-root is the only option required for the Composer integration.

{
    "extra": {
        "drupal-root": "docroot/"
    }
}

The Composer integration works well with composer/installers but this is not an explicit dependency. When composer/installers is available, you can install Drupal modules, themes, profiles and Drush plugins.

The snippet below is an example based on the composer/installers documentation and depends on drupal-root being set to docroot/ (as above).

{
    "extra": {
        "installer-paths": {
            "docroot/profiles/special/modules/custom/amazing": [
                "somebody/amazing-module"
            ],
            "docroot/profiles/special/": [
                "somebody/special-profile"
            ],
            "docroot/sites/all/modules/{$name}/": [
                "type:drupal-module"
            ],
            "docroot/sites/all/themes/{$name}/": [
                "type:drupal-theme"
            ],
            "docroot/sites/all/libraries/{$name}/": [
                "type:drupal-library"
            ],
            "docroot/profiles/{$name}/": [
                "type:drupal-profile"
            ],
            "docroot/sites/all/drush/{$name}/": [
                "type:drupal-drush"
            ]
        }
    }
}

The name of the directory where a profile is installed apparently must be named precisely for the same as its info file.

Drupal install

{
    "repositories": [
        {
            "type": "package",
            "package": {
                "name": "drupal/drupal",
                "version": "7.x-dev",
                "dist": {
                    "type": "tar",
                    "url": "http://ftp.drupal.org/files/projects/drupal-7.x-dev.tar.gz"
                },
                "source": {
                    "type": "git",
                    "url": "git://git.drupal.org/project/drupal.git",
                    "reference": "7.x"
                },
                "bin": [
                    "scripts/drupal.sh",
                    "scripts/password-hash.sh"
                ],
                "require": {
                    "php": ">=5.2.4",
                    "ext-date": "*",
                    "ext-dom": "*",
                    "ext-filter": "*",
                    "ext-gd": "*",
                    "ext-hash": "*",
                    "ext-json": "*",
                    "ext-pcre": "*",
                    "ext-PDO": "*",
                    "ext-session": "*",
                    "ext-SimpleXML": "*",
                    "ext-SPL": "*",
                    "ext-xml": "*"
                }
            }
        }
    ],
    "require": {
        "drupal/drupal": "~7.0@dev",
        "drufony/drupal-bridge": "~1.0@dev"
    },
    "extra": {
        "drupal-install": {
            "symlink": true,
            "relative": true
        }
    },
    "scripts": {
        "create-sites-dir": "Bangpound\\Bridge\\Drupal\\Composer\\ScriptHandler::createSitesDir",
        "post-install-cmd": [
            "Bangpound\\Bridge\\Drupal\\Composer\\ScriptHandler::prepareDrupalRoot"
        ],
        "post-update-cmd": [
            "Bangpound\\Bridge\\Drupal\\Composer\\ScriptHandler::prepareDrupalRoot"
        ]
    }
}

When you define drupal/drupal as a dependency, the post-install-cmd and post-update-cmd scripts will (by default) create a relative symlink of the includes, misc, modules, and themes directory. The profiles directory is left out so that these can be managed by the composer/installers plugin for Drupal profile projects.

Core profiles

The core profile for standard and minimal installs can be obtained from the Drufony package repository. Just merge this snippet into your composer.json file. Also configure your installer-paths as described above so that the profiles are installed into the Drupal root's profiles directory.

{
    "repositories": [
        {
            "type": "composer",
            "url": "http://drufony.github.io/packages.json"
        }
    ],
    "require": {
        "drupal/minimal": "7.*@dev",
        "drupal/standard": "7.*@dev"
    }
}

Drush command

{
    "require": {
        "drush/drush": "dev-master"
    },
    "scripts": {
        "drush": "Bangpound\\Bridge\\Drupal\\Drush\\Composer\\ScriptHandler::drushCommand"
    }
}

composer drush updatedb
