iTasks Installation Tasks

A collection of small chunks of code.

Used in conjunction with the iTasks installation profile to provide granular installation tasks.

Theory

Do one thing. And do it well! The concept behind this collection of code is to do one thing per file. This way the amount of change any one thing has is minimal. A smaller footprint will help with encapsulation and decoupling.

This collection of code should be sharable and re-usable. Keeping tasks well named and namespaced will help to reduce duplication of effort and collisions as multiple parties contribute to the shared code bank.

Creating a new namespace

When creating a new namespace for your installation profile be unique. An organization name, url, or group might help. For us at Stanford we have many sub groups and created a many level namespace: Eg: Stanford\WebServices\Jumpstart\JumpstartAcademic

This namespace would be for Stanford's Web Services group's Jumpstart Academic distribution from the Jumpstart distribution line.

Please follow PSR-4 naming conventions: http://www.php-fig.org/psr/psr-4/

Creating a new install task

Please follow PSR-4 naming conventions: http://www.php-fig.org/psr/psr-4/

Install tasks should always be placed in an Install folder and then named descriptively. Install task files should always be named the same as the class name. The class should always extend \ITasks\AbstractInstallTask. The AbstractInstallTask class is found in the installation profile and not in this repository. Each install task has one required method called execute. Please see the boilerplate code below.

<?php
/**
 * @file
 * Abstract Task Class
 */

namespace Organization\Group\Project\Install;
use \ITasks\AbstractInstallTask;

class MyInstallTaskName extends AbstractInstallTask {

  /**
   * Description of execute method.
   *
   * @param array $args
   *  Installation arguments.
   */
  public function execute(&$args = array()) {
    // Enable user picture support and set the default to a square thumbnail option.
    variable_set('user_pictures', '1');
  }

  /**
   * A list of requirements.
   */
  public function requirements() {
    return array(
      'user',
    );
  }

}

Creating a new update task

Please follow PSR-4 naming conventions: http://www.php-fig.org/psr/psr-4/

Update tasks should always be placed in an Update folder and then named descriptively. Update task files should always be named the same as the class name. The class should always extend \ITasks\AbstractUpdateTask. The AbstractUpdateTask class is found in the installation profile and not in this repository. Each update task has one required method called execute and should include a $description variable. Please see the boilerplate code below.

<?php
/**
 * @file
 * Abstract Task Class.
 */
namespace Organization\Group\Project;
use \ITasks\AbstractUpdateTask;

/**
 *
 */
class MyUpdateTask extends AbstractUpdateTask {

  // Description of update task.
  protected $description = "Change the site name to my new site name";

  /**
   * Description of execute task.
   *
   * @param array $args
   *   Installation arguments.
   */
  public function execute(&$args = array()) {
    variable_set("site_name", "My New Site Name IS: " . md5(time()));
  }

}

Installation Task Anatomy

Variables

$displayName
string
The name displayed during installation through the UI

$display
bool
Wether to display the name in the UI or not.

$installType
string
See type: https://api.drupal.org/api/drupal/modules!system!system.api.php/function/hook_install_tasks/7.x

$installRun
int
See run: https://api.drupal.org/api/drupal/modules!system!system.api.php/function/hook_install_tasks/7.x

This is the meat of the whole class. Add your specific functionality here.

requirements()
Returns an array of module machine names that are dependencies of this install task.

getMachineName()
Returns the machine name of this task.

setMachineName()
Sets the machine name of this task.

InstallTasksAlter(&$tasks)
The passed in parameter is an array of installation tasks. This function allows tasks to alter the array of installation tasks. This means they can change the order, add, or remove tasks conditionally.

getDisplayName()
Returns the value of $displayName or the classname if undefined.

getInstallDisplay()
Returns the value of $display.

getRunType()
Returns the value of $installRun.

getInstallType()
Returns the value of $installType.

getInstallFunction()
Returns the value of $installFunction.

setDescription($desc)
Sets the value of $description with the passed in value.

getDescription()
Returns the value of $description or default text if not set.

form()
