What is wrong about Drush Make?

• Making is slow

• Making is frail

• Drush Make is not intended for rebuilding

Get off the island […] get involved in the wider PHP community, both to learn

from it and to share with it.

What is right about Drush Make

• Overview of used

projects

• Supports patching

• Support for non-Drupal

code

projects[feedback_simple][subdir] = contrib projects[feedback_simple][version] = 1.6 !projects[feeds][subdir] = contrib projects[feeds][version] = 2.0-alpha7 ; Support the use of summary on body fields.

5 minute Composer crash course

What is Composer?Composer is a project dependency manager,

not a package manager.

!

Inspired by Ruby Bundler and Node.JS npm

!

Cross-platform compatible (Windows, Linux, and OSX)

Requires >= PHP 5.3.2 and

optionally Subversion, GIT, and/or Mercurial

!

Released in 2011 under the MIT license

Developed by: Nils Adermann and Jordi Boggiano

What does Composer do?

• Manages dependent

libraries

• Handles cascading

dependencies

• Declarative dependency

• Install and update

dependencies

• Autoload dependencies

{ "name": "kasperg/composer-demo", "description": "A demo Composer project", "require": { "silex/silex": "1.1.*" }, "authors": [ { "name": "Kasper Garnaes", "email": "kasper@reload.dk" } ] }

Live demo

Packagist

• Over 40.000 packages

• Default package repository for Composer

• Contains nearly every widely used open source PHP package

• Free accounts to register and maintain own packages

Composer vs. Drush Make

• Manages dependent

libraries

• Handles cascading

dependencies

• Declarative dependency

# composer.json { "require": { "silex/silex": "1.1.*" }, } !!!# drush.make api = 2 core = 7.x projects[ctools][version] = 1.4

Time to jump through some hoops

Lets get started!

Drupal Core

• Located in the root directory of the project

• Use Composer custom installers

• Example: Composer non-destructive archive installer

• https://github.com/azt3k/non-destructive-archive-installer

Modules and themes I

• Composer repository for Drupal projects

• Developed by Will MiltonLead technology architect, Promet Source

• http://static.drupal-packagist.org/v0.2.0/

• Source: https://github.com/winmillwill/drupal-parse-composer

Modules and themes II

• Package naming:drupal/[project-name]

• Version naming:[drupal-major-version]. [project-major-version]. [project-minor-version]

• http://static.drupal-packagist.org/v0.2.0/

• Source: https://github.com/winmillwill/drupal-parse-composer

Modules and themes III

• Move projects to the appropriate location using Composer Installers

• http://composer.github.io/installers/

• Supports individual projects and types including drupal-module, drupal-theme, drupal-profile, drupal-drush

Patches

• Composer does not support patching projects. It promotes a fork/pullrequest-based workflow.

• Use Composer Patches Plugin

• Developed for TYPO3

• https://github.com/netresearch/composer-patches-plugin

Libraries

• Packagist packages can be added through requires

• Includes PHP but also JS, CSS!

• Packages without composer support can be defined manually through composer.json

• Same approach applies for sandboxes

• Composer can support the same use cases as Drush Make in the development process and more through community work.

• Enables tapping into and sharing with the PHP community at large.

Wrap up

By Richard Paterson, https://flic.kr/p/6wnBHM

Project template

• Use a project template to get started and avoid repeating boilerplate configuration

• php composer.phar create-project reload/drupal-composer-project some-dir --stability dev —no-interaction

• https://github.com/reload/drupal-composer-project

Whats next?

Drupal composer repository

• drupal.org must provide an authoritative Composer repository for Drupal packages.

• Could replace updates.drupal.org over time.

• Until then: Continued work on static.drupal-packagist.org.

!

The Future of Drush

• Relevant as ever

• Reduced scope

• make and dl no longer

needed

What about Drupal 8?

• Already has a composer.json file

in the project root.

• Better directory structure makes things a lot easier.

• Drupal 8 core directory subslit can be used as a Composer package
