Hi all, I am attaching the slides to the talk I gave today about custom code.
Also, I mentioned "drush make" and promised to post some example code. The following is an example of a section from a drush make file showing the version and patches for a couple of media-related modules. This shows how the drush make file can be useful to "lock down" a particular version/patch combination:
projects[media][download][type] = git
projects[media][download][revision] = 89287f76df1ff24409b3ec474c59218929385733
projects[media][download][branch] = 7.x-2.x
projects[media][patch][] = https://www.drupal.org/files/issues/wysiwyg_alt_and_title-2416701-30.patch
projects[media][patch][] = https://www.drupal.org/files/issues/view_mode_classes-2422153-9.patch
projects[media][patch][] = https://www.drupal.org/files/issues/remove_references_to-2714581-2.patch
projects[media][patch][] = https://www.drupal.org/files/issues/cannot_put_link_on_an-2707107-4.patch
projects[media_ckeditor][download][type] = git
projects[media_ckeditor][download][revision] = 7409f2c0923f7bd81e91303a9d6032505d89d1cf
projects[media_ckeditor][download][branch] = 7.x-2.x
projects[media_ckeditor][patch][] = https://www.drupal.org/files/issues/ckeditor_converting-2707177-2.patch
projects[media_ckeditor][patch][] = https://www.drupal.org/files/issues/media-insert_widget-2451959-7.patch
projects[media_ckeditor][patch][] = https://www.drupal.org/files/issues/add_entry_in_ckeditor_s-2711129-2.patch
projects[media_ckeditor][patch][] = https://www.drupal.org/files/issues/the_toolbar_button_does-2710841-2.patch
projects[media_ckeditor][patch][] = https://www.drupal.org/files/issues/2455557-4.patch
projects[media_ckeditor][patch][] = https://www.drupal.org/files/issues/open_media_popup_on-2713757-2.patch
projects[media_ckeditor][patch][] = https://www.drupal.org/files/issues/add_classes_to_the-2712923-5.patch
On the other hand, if you simply need to use a specific stable version of a module, the syntax is much simpler. For example:
projects[pathologic][version] = 2.12
projects[plupload][version] = 1.6
Feel free to send any questions my way!
