-Plugin Hooks
-============
-
-Application Hooks
------------------
-
-Hooks can extend, replace, filter data or change the default behavior. Each hook is identified with a unique name, example: `controller:calendar:user:events`
-
-### Listen on hook events
-
-In your `initialize()` method you need to call the method `on()` of the class `Kanboard\Core\Plugin\Hook`:
-
-```php
-$this->hook->on('hook_name', $callable);
-```
-
-The first argument is the name of the hook and the second is a PHP callable.
-
-### Hooks executed only once
-
-Some hooks can have only one listener:
-
-#### model:subtask-time-tracking:calculate:time-spent
-
-- Override time spent calculation when sub-task timer is stopped
-- Arguments:
-    - `$user_id` (integer)
-    - `$start` (DateTime)
-    - `$end` (DateTime)
-
-### Merge hooks
-
-"Merge hooks" act in the same way as the function `array_merge`. The hook callback must return an array. This array will be merged with the default one.
-
-Example to add events in the user calendar:
-
-```php
-class Plugin extends Base
-{
-    public function initialize()
-    {
-        $container = $this->container;
-
-        $this->hook->on('controller:calendar:user:events', function($user_id, $start, $end) use ($container) {
-            $model = new SubtaskForecast($container);
-            return $model->getCalendarEvents($user_id, $end); // Return new events
-        });
-    }
-}
-```
-
-Example to override default values for task forms:
-
-```php
-class Plugin extends Base
-{
-    public function initialize()
-    {
-        $this->hook->on('controller:task:form:default', function (array $default_values) {
-            return empty($default_values['score']) ? array('score' => 4) : array();
-        });
-    }
-}
-```
-
-List of merging hooks:
-
-#### controller:task:form:default
-
-- Override default values for task forms
-- Arguments:
-    - `$default_values`: actual default values (array)
-
-#### controller:calendar:project:events
-
-- Add more events to the project calendar
-- Arguments:
-    - `$project_id` (integer)
-    - `$start` Calendar start date (string, ISO-8601 format)
-    - `$end` Calendar` end date (string, ISO-8601 format)
-
-#### controller:calendar:user:events
-
-- Add more events to the user calendar
-- Arguments:
-    - `$user_id` (integer)
-    - `$start` Calendar start date (string, ISO-8601 format)
-    - `$end` Calendar end date (string, ISO-8601 format)
-
-Asset Hooks
------------
-
-Asset hooks can be used to add a new stylesheet easily or a new JavaScript file in the layout. You can use this feature to create a theme and override all Kanboard default styles.
-
-Example to add a new stylesheet:
-
-```php
-<?php
-
-namespace Kanboard\Plugin\Css;
-
-use Kanboard\Core\Plugin\Base;
-
-class Plugin extends Base
-{
-    public function initialize()
-    {
-        $this->hook->on('template:layout:css', array('template' => 'plugins/Css/skin.css'));
-    }
-}
-```
-
-List of asset Hooks:
-
-- `template:layout:css`
-- `template:layout:js`
-
-
-Reference hooks
----------------
-
-Reference hooks are passing a variable by reference.
-
-Example:
-
-```php
-$this->hook->on('formatter:board:query', function (\PicoDb\Table &query) {
-    $query->eq('color_id', 'red');
-});
-```
-
-The code above will show only tasks in red on the board.
-
-List of reference hooks:
-
-| Hook                                       | Description                                                   |
-|--------------------------------------------|---------------------------------------------------------------|
-| `formatter:board:query`                    | Alter database query before rendering board                   |
-| `pagination:dashboard:task:query`          | Alter database query for tasks pagination on the dashboard    |
-| `pagination:dashboard:subtask:query`       | Alter database query for subtasks pagination on the dashboard |
-| `model:task:creation:prepare`              | Alter form values before to save a task                       |
-| `model:task:modification:prepare`          | Alter form values before to edit a task                       |
-| `model:color:get-list`                     | Alter default_colors values                                   |
-| `model:subtask:modification:prepare`       | Alter form values before to save a subtask                    |
-| `model:subtask:creation:prepare`           | Alter form values before to edit a subtask                    |

-Template Hooks
---------------
-
-Template hooks allow to add new content in existing templates.
-
-Example to add new content in the dashboard sidebar:
-
-```php
-$this->template->hook->attach('template:dashboard:sidebar', 'myplugin:dashboard/sidebar');
-```
-
-Example to attach a template with local variables:
-
-```php
-$this->template->hook->attach('template:dashboard:sidebar', 'myplugin:dashboard/sidebar', array(
-    'variable' => 'foobar',
-));
-```
-
-Example to attach a template with a callable:
-
-```php
-$this->template->hook->attach('template:dashboard:sidebar', 'myplugin:dashboard/sidebar', function($hook_param1, $hook_param2) {
-    return array('new_template_variable' => 'foobar'); // Inject a new variable into the plugin template
-});
-```
-
-This call is usually defined in the `initialize()` method.
-The first argument is name of the hook and the second argument is the template name.
-
-Template names prefixed with the plugin name and colon indicate the location of the template.
-
-Example with `myplugin:dashboard/sidebar`:
-
-- `myplugin` is the name of your plugin (lowercase)
-- `dashboard/sidebar` is the template name
-- On the filesystem, the plugin will be located here: `plugins\Myplugin\Template\dashboard\sidebar.php`
-- Templates are written in pure PHP (don't forget to escape data)
-
-Template names without prefix are core templates.
-
