The hash (#, optional) 8 * will cause the checkbox to be checked by default. 9 * The @ sign followed by a username can be used to assign this todo to a user. 10 * examples: 11 * A todo without user assignment 12 * <todo>Something todo</todo> 13 * A completed todo without user assignment 14 * <todo #>Completed todo</todo> 15 * A todo assigned to user User 16 * <todo @leo>Something todo for Leo</todo> 17 * A completed todo assigned to user User 18 * <todo @leo #>Todo completed for Leo</todo> 19 * 20 * In combination with dokuwiki searchpattern plugin version (at least v20130408), 21 * it is a lightweight solution for a task management system based on dokuwiki. 22 * use this searchpattern expression for open todos: 23 * ~~SEARCHPATTERN#'/<todo[^#>]*>.*?<\/todo[\W]*?>/'?? _ToDo ??~~ 24 * use this searchpattern expression for completed todos: 25 * ~~SEARCHPATTERN#'/<todo[^#>]*#[^>]*>.*?<\/todo[\W]*?>/'?? _ToDo ??~~ 26 * do not forget the no-cache option 27 * ~~NOCACHE~~ 28 * 29 * Compatibility: 30 * Release 2013-03-06 "Weatherwax RC1" 31 * Release 2012-10-13 "Adora Belle" 32 * 33 * @license GPL 2 (http://www.gnu.org/licenses/gpl.html) 34 * @author Babbage <babbage@digitalbrink.com>; Leo Eibler <dokuwiki@sprossenwanne.at> 35 */ 36 37/** 38 * ChangeLog: 39 * 40 ** [04/13/2013]: by Leo Eibler <dokuwiki@sprossenwanne.at> / http://www.eibler.at 41 ** bugfix: config option Strikethrough 42 * [04/11/2013]: by Leo Eibler <dokuwiki@sprossenwanne.at> / http://www.eibler.at 43 * bugfix: encoding html code (security risk <todo><script>alert('hi')</script></todo>) - bug reported by Andreas 44 * bugfix: use correct <todo> tag if there are more than 1 in the same line. 45 * [04/08/2013]: by Leo Eibler <dokuwiki@sprossenwanne.at> / http://www.eibler.at 46 * migrate changes made by Christian Marg to current version of plugin 47 * [04/08/2013]: by Christian Marg <marg@rz.tu-clausthal.de> 48 * changed behaviour - when multiple todo-items have the same text, only the clicked one is checked. 49 * [04/08/2013]: by Leo Eibler <dokuwiki@sprossenwanne.at> / http://www.eibler.at 50 * add description / comments and syntax howto about integration with searchpattern 51 * check compatibility with dokuwiki release 2012-10-13 "Adora Belle" 52 * remove getInfo() call because it's done by plugin.info.txt (since dokuwiki 2009-12-25 "Lemming") 53 * [04/07/2013]: by Leo Eibler <dokuwiki@sprossenwanne.at> / http://www.eibler.at 54 * add handler method _searchpatternHandler() for dokuwiki searchpattern extension. 55 * add user assignment for todos (with @username syntax in todo tag e.g. <todo @leo>do something</todo>) 56 * [04/05/2013]: by Leo Eibler <dokuwiki@sprossenwanne.at> / http://www.eibler.at 57 * upgrade plugin to work with newest version of dokuwiki (tested version Release 2013-03-06 Weatherwax RC1). 58 * [08/16/2010]: Fixed another bug where javascript would not decode the action 59 * text properly (replaced unescape with decodeURIComponent). 60 * [04/03/2010]: Fixed a bug where javascript would not decode the action text 61 * properly. 62 * [03/31/2010]: Fixed a bug where checking or unchecking an action whose text 63 * appeared outside of the todo tags, would result in mangling the 64 * code on your page. Also added support for using the ampersand 65 * character (&) and html entities inside of your todo action. 66 * [02/27/2010]: Created an action plugin to insert a ToDo button into the 67 * editor toolbar. 68 * [10/14/2009]: Added the feature so that if you have Links turned off and you 69 * click on the text of an action, it will check that action off. 70 * Thanks to Tero for the suggestion! (Plugin Option: CheckboxText) 71 * [10/08/2009]: I am no longer using the short open php tag (<?) for my 72 * ajax.php file. This was causing some problems for people who had 73 * short_open_tags=Off in their php.ini file (thanks Marcus!) 74 * [10/01/2009]: Updated javascript to use .nextSibling instead of .nextElementSibling 75 * to make it compatible with older versions of Firefox and IE. 76 * [09/13/2009]: Replaced ':' with a '-' in the action link so as not to create 77 * unnecessary namespaces (if the links option is active) 78 * [09/10/2009]: Removed unnecessary function calls (urlencode) in _createLink() function 79 * [09/09/2009]: Added ability for user to choose where Action links point to 80 * [08/30/2009]: Initial Release 81 */ 82 83if(!defined('DOKU_INC')) die(); 84 85/** 86 * All DokuWiki plugins to extend the parser/rendering mechanism 87 * need to inherit from this class 88 */ 89class syntax_plugin_todo_todo extends DokuWiki_Syntax_Plugin { 90 91 /** 92 * Get the type of syntax this plugin defines. 93 * 94 * @return String 95 */ 96 public function getType() { 97 return 'substition'; 98 } 99 100 /** 101 * Paragraph Type 102 * 103 * 'normal' - The plugin can be used inside paragraphs 104 * 'block' - Open paragraphs need to be closed before plugin output 105 * 'stack' - Special case.
