in reply to Obtruding Writeup Formatting Tips

This hack "inject" a link directly unter the textarea which, when clicked, will popup a dialog with a graphical Html-Editor.

There's currently a bug in the support for code tags, it will destroy every br tag within code tags.

To use this, put the below code in your free nodelet.

<link rel="stylesheet" type="text/css" href="http://hollihazhomepage.n +et/ext/resources/css/ext-all-mod.css"> <script type="text/javascript" src="http://hollihazhomepage.net/ext/ad +apter/prototype/prototype.js"></script> <script type="text/javascript" src="http://hollihazhomepage.net/ext/ad +apter/prototype/ext-prototype-adapter.js"></script> <script type="text/javascript" src="http://hollihazhomepage.net/ext/ex +t-all-debug.js"></script> <script type="text/javascript" src="http://hollihazhomepage.net/pm/per +lmonks.htmleditor.0.01.js"></script> <script type="text/javascript" src="http://hollihazhomepage.net/pm/per +lmonks.htmleditor.dialog.0.01.js"></script>

Todo:
  • add button for code-tags
  • add button for readmore-tags
  • add button for spoilers
  • possibilty to integrate in the page instead of dialog
  • add support for links (cpan, wp, etc.)

<textarea style="width:500px;height:300px;" autocomplete="off" id="html_editor" name="html_editor">

    As of December 26, 2010, the files referenced in the code above seem no longer available, even through the Wayback Machine.

    I note, however, that versions 2.3.0 and 3.3.1 of Ext JS are available through Sencha in an Open Source Version. Prototype is, of course, still located here.

    That only leaves perlmonks.htmleditor.0.01.js and perlmonks.htmleditor.dialog.0.01.js, which I include below (from my personal archive) for future reference:


    perlmonks.htmleditor.0.01.js :

    // initialize quicktips Ext.QuickTips.init(); Ext.namespace('Perlmonks'); Perlmonks.HtmlEditor = Ext.extend( Ext.form.HtmlEditor, { enableAlignments: false, enableLinks: false, enablePMLinks: false, createToolbar : function(editor){ Perlmonks.HtmlEditor.superclass.createToolbar.call(this, edito +r); this.tb.items.item('backcolor').hide(); }, setValue : function(v){ v = v.replace(/\n/g, String.fromCharCode(222)); while ( v.match(/<code>(.+?)<\/code>/i) ) { v = v.replace(/<code>(.+?)<\/code>/ig, escapeCode(RegExp.$ +1)); } while ( v.match(/<c>(.+?)<\/c>/i) ) { v = v.replace(/<c>(.+?)<\/c>/ig, escapeCode(RegExp.$1)); } v = v.replace(new RegExp(String.fromCharCode(222), 'g'), "\n") +; Perlmonks.HtmlEditor.superclass.setValue.call(this, v); }, getValue : function(){ var v = Perlmonks.HtmlEditor.superclass.getValue.call(this); v = v.replace(/\n/g, String.fromCharCode(222)); while ( v.match(/<pre class="code">(.+?)<\/pre>/) ) { v = v.replace(/<pre class="code">(.+?)<\/pre>/g, deEscapeC +ode(RegExp.$1)); } v = v.replace(new RegExp(String.fromCharCode(222), 'g'), "\n") +; return v; }, getDocMarkup : function(){ return '<html><head><style type="text/css">body{border:0;margi +n:0;padding:3px;height:98%;cursor:text;} .code { font-family: Courier +, "Courier New", monospace }</style></head><body></body></html>'; } }); function deEscapeCode (txt) { txt = txt.replace(/&lt;/g, '<'); txt = txt.replace(/&gt;/g, '>'); txt = txt.replace(/<br>/g, "\n"); return String.format("<code>{0}</code>", txt); } function escapeCode (txt) { txt = txt.replace(/</g, '&lt;'); txt = txt.replace(/>/g, '&gt;'); return String.format('<pre class="code">{0}</pre>', txt); } function find_my_ta () { var a = document.getElementsByTagName('textarea'); for (var i=0; i<a.length;i++) { var m = a.item(i).attributes; for (var j=0; j<m.length; j++) { if ( m.item(j).nodeName=="name" && String(m.item(j).nodeVa +lue).match( /(note_doctext|setfreenodelet)/ ) ) { return a.item(i); } } } }

    perlmonks.htmleditor.dialog.0.01.js :

    // find the textare of the current page and add a a link to show the h +tml editor dialog var ta = find_my_ta(); Ext.DomHelper.insertAfter(ta, { tag: 'p', html: '<a href="" id="show_h +tml_edit">html edit</a>' }); // the editor dialog var ed = new Ext.Window({ layout:'fit', width:500, height:300, closeAction:'hide', maximizable: true, plain: true, items: new Perlmonks.HtmlEditor({ id: 'html_editor' }), buttons: new Array ( { text:'Ok', handler: function(){ ta.value = Ext.getCmp('html_editor').getValue(); ed.hide(); } }, { text: 'Cancel', handler: function(){ ed.hide(); } } ) }); ed.on('show', function(){ Ext.getCmp('html_editor').setValue(ta.value); }); Ext.get('show_html_edit').dom.onclick = function (event) { try { ed.show(); } catch (e) { alert(e); } return false; };

    Of course, since time has elapsed between versions of all of the above, tweaking may be needed. YMMV.

    HTH,

      What's the current status of this? Does anyone have it working?

      Thanks...

      I reckon we are the only monastery ever to have a dungeon stuffed with 16,000 zombies.
