7.x 2.x drush at require

With Drush (5.x+) and at_base.module, we can tell Drush to download our dependencies (libraries, Drupal themes, Drupal modules).

First, define the config file:

# File: @my_module/config/require.yml

projects:
  pimple:
    type: library
    download:
      type: git
      url: https://github.com/fabpot/Pimple.git
      revision: dc03a407f20cbd4eaf55472875ad47ee96d921ea

  twig:
    type: library
    download:
      type: git
      url: https://github.com/fabpot/Twig.git
      branch: v1.15.0

  expression_language:
    type: library
    download:
      type: git
      url: https://github.com/symfony/expression-language.git
      branch: v2.4.0
    # Use this option if we would like keep git structure of library
    options: { working-copy: TRUE }

Then we can download them fastly:

drush at_require my_module
