/* Sysop decrier/detector (rights group displayer), version [0.2.0a] Originally from http://en.wikipedia.org/wiki/User:Splarka/sysopdectector.js   Notes: * Fixed this up to use the new API fun stuffs. * Shows all groups now * nstab-user isn't available in all skins, all skins have at least one h1 or h2 I believe. * heading given class="detected-userrights-heading" and text in span class="detected-userrights"   Options: * Now supports an option system.  * By setting a datalet true it shows in the header instead of the title. * Note, all are assumed false if omitted. All but 'groups' are assumed false if undefined. var showUserGroupSettings = {   'IP':true,   'unregistered':true,   'registered':true,   'groups': true,   'groupless': true,   'editcount':true,   'regdate':true,   'blocked':true }; */   if((mw.config.get('wgNamespaceNumber') == 2 || mw.config.get('wgNamespaceNumber') == 3) && mw.config.get('wgTitle').indexOf('/') == -1 && (mw.config.get('wgAction') != 'edit' || mw.config.get('wgAction') != 'submit')) $(showUserGroups) function showUserGroups() {   var url = mw.config.get('wgServer') + mw.config.get('wgScriptPath') + '/api.php?action=query&format=json&callback=showUserGroupsCB&maxage=3600&smaxage=3600&usprop=blockinfo|groups|editcount|registration&list=users&ususers=' + encodeURIComponent(mw.config.get('wgTitle'));   mw.loader.load(url); }   function showUserGroupsCB(obj) {   var show = window.showUserGroupSettings || false;   if(!obj['query'] || !obj['query']['users']) return   var user = obj['query']['users'];   if(user.length == 0) return   user = user[0];   var someHeading = document.getElementsByTagName('h1')[0] || document.getElementsByTagName('h2')[0]   if(!someHeading) return     var span = document.createElement('span');   var title = 'User:' + user['name'] + ' ';   var text = ' ';     if(user['invalid'] == '') {     if(show && show.IP) text += '[IP] '     else title += '[invalid or IP username] '   } else if(user['missing'] == '') {     if(show && show.unregistered) text += '[doesn\'t exist] '     else title += '[not a registered name] '   } else {     if(show && show.registered) text += '[exists] '     else title += '[username registered] '     if(user['groups']) {       if(show && show.groups || !show) text += '[user,' + user['groups'] + '] '       else title += '[user,' + user['groups'] + '] '     } else {       if(show && show.groupless) text += '[user] '       else title += '[user] '     }     if(user['editcount']) {       if(show && show.editcount) text += '[' + user['editcount'] + ' edits] '       else title += '[' + user['editcount'] + ' edits] '     }     if(user['registration']) {       if(show && show.regdate) text += '[created: ' + user['registration'].split('T')[0] + '] '       else title += '[created: ' + user['registration'] + '] '     }     if(user['blockedby']) {        if(show && show.blocked) text += '[blocked] '       else text += '[currently blocked] '     }   }     span.setAttribute('class','detected-userrights');   span.appendChild(document.createTextNode(text));   someHeading.appendChild(span);   someHeading.setAttribute('title',title);   someHeading.className += ' detected-userrights-heading'; }
