+# +#
+# +#
+#
+# +# ### 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. + +incomplete = "[ ]" +complete = "[x]" + +# Escapes the String for regular expression matching. +escapePattern = (str) -> + str. + replace(/([\[\]])/g, "\\$1"). # escape square brackets + replace(/\s/, "\\s"). # match all white space + replace("x", "[xX]") # match all cases + +incompletePattern = /// + #{escapePattern(incomplete)} +/// +completePattern = /// + #{escapePattern(complete)} +/// + +# Pattern used to identify all task list items. +# Useful when you need iterate over all items. +itemPattern = /// + ^ + (?: # prefix, consisting of + \s* # optional leading whitespace + (?:>\s*)* # zero or more blockquotes + (?:[-+*]|(?:\d+\.)) # list item indicator + ) + \s* # optional whitespace prefix + ( # checkbox + #{escapePattern(complete)}| + #{escapePattern(incomplete)} + ) + \s+ # is followed by whitespace + (?! + \(.*?\) # is not part of a [foo](url) link + ) + (?= # and is followed by zero or more links + (?:\[.*?\]\s*(?:\[.*?\]|\(.*?\))\s*)* + (?:[^\[]|$) # and either a non-link or the end of the string + ) +/// + +# Used to filter out code fences from the source for comparison only. +# http://rubular.com/r/x5EwZVrloI +# Modified slightly due to issues with JS +codeFencesPattern = /// + ^`{3} # ``` + (?:\s*\w+)?
