# TaskList Behavior
#
#= provides tasklist:enabled
#= provides tasklist:disabled
#= provides tasklist:change
#= provides tasklist:changed
#
#
# Enables Task List update behavior.
#
# ### Example Markup
#
# <div class="js-task-list-container">
# <ul class="task-list">
# <li class="task-list-item">
# <input type="checkbox" class="js-task-list-item-checkbox" disabled />
# text
# </li>
# </ul>
# <form>
# <textarea class="js-task-list-field">- [ ] text</textarea>
# </form>
# </div>
#
# ### Specification
#
# TaskLists MUST be contained in a `(div).js-task-list-container`.
#
# TaskList Items SHOULD be an a list (`UL`/`OL`) element.
#
# Task list items MUST match `(input).task-list-item-checkbox` and MUST be
# `disabled` by default.
#
# TaskLists MUST have a `(textarea).js-task-list-field` form element whose
# `value` attribute is the source (Markdown) to be udpated. The source MUST
# follow the syntax guidelines.
#
# TaskList updates trigger `tasklist:change` events. If the change is
# successful, `tasklist:changed` is fired. The change can be canceled.
#
# jQuery is required.
#
# ### Methods
#
# `.taskList('enable')` or `.taskList()`
#
# Enables TaskList updates for the container.
#
# `.taskList('disable')`
#
# Disables TaskList updates for the container.
#
## ### Events
#
# `tasklist:enabled`
#
# Fired when the TaskList is enabled.
#
# * **Synchronicity** Sync
# * **Bubbles** Yes
# * **Cancelable** No
# * **Target** `.js-task-list-container`
#
# `tasklist:disabled`
#
# Fired when the TaskList is disabled.
#
# * **Synchronicity** Sync
# * **Bubbles** Yes
# * **Cancelable** No
# * **Target** `.js-task-list-container`
#
# `tasklist:change`
#
# Fired before the TaskList item change takes affect.
#
# * **Synchronicity** Sync
# * **Bubbles** Yes
# * **Cancelable** Yes
# * **Target** `.js-task-list-field`
#
# `tasklist:changed`
#
# Fired once the TaskList item change has taken affect.
#
# * **Synchronicity** Sync
# * **Bubbles** Yes
# * **Cancelable** No
# * **Target** `.js-task-list-field`
#
# ### NOTE
#
# Task list checkboxes are rendered as disabled by default because rendered
# user content is cached without regard for the viewer.
