and so forth. Everything else are block elements. A lot of logic depends on a rule that the cursor will always be inside exactly one paragraph element (a <p> for instance). Obviously (it follows from the above rule and the HTML standard) all inline and empty elements must also be inside exactly one such element. You can add an element that is not supported simply by adding appropriate lines below. All creation and manipulation of elements relies on information from this elements-object. Even the GUI buttons are currently created automatically from that.

Edit in Place with JavaScript and CSS

Editable Content

Editable #1: Double-click anywhere in this paragraph to edit its content. Press TAB or click outside the edit area to finish. Press ESCAPE to cancel.

Editable #2: This can work on arbitrary markup. This may or may not be such a good idea.

We can do paragraphs, styling, <a href="http://tool-man.org/examples/index.html">links</a>, or any HTML, really.

	DADA	NHUG	TTAY
DADA		1	3
NHUG	1		2
TTAY	3	2

Without applying some kind of limitation, any markup whatsoever can be entered. In practice you would normally want to limit the type of markup allowed perhaps via a <a href="http://tinymce.moxiecode.ru/">wysiwyg editor</a> or a text formatter like <a href="http://daringfireball.net/projects/markdown/">Markdown</a>.

Sortable, Editable Lists

Combining in place editing with <a href="http://tool-man.org/examples/sorting.html">Drag & Drop Sortable Lists</a> results in nice direct manipulation for managing a list of labels.

List 1	List 2	List 3

This is a wysiwyg HTML-editor. You can write text directly into the browser window:

I

 WALTER - an in-browser WYSIWYG HTML editor written in JavaScript
 Walter will intercept your keystrokes and insert text to the webpage you
 are viewing in your broswer. The idea is to turn your browser into a
 WYSIWYG HTML editor.
 Main uses for Walter might be as a replacement for a <textarea> in
  - chats and bulletinboards
  - content management systems
 ...given that Linux IMHO currently has no WYsIWYG HTML-editors, I
 could see Walter becoming one. But let"s not get carried away.
 MAIN PHILOSOPHY
 Main philosophy of Walter is:
   - the wysiwyg part is handled by the fact, that we are doing this in
     a browser
   - The W3C DOM allows any kind of manipulation of the HTML in a page
   - We just have to intercept keystrokes and commands from the user
     (this is a little tricky) and actually implementing the DOM manipulation
     (first release of walter already had 790 lines of JavaScript)
 CURRENT FEATURES
 Walter currently knows how to write and erase (backspace) text. Enter makes
 a new paragraph, shift+enter a br. Any inline tags can work (b, i, img, a)
 but only the most common are exposed as buttons.
 p and heading elements are supported, but not tables, lists or other "large"
 block elements.
 There is no support for mouse movements and also no other way of marking text.
 Thus bold and other effects can only be used while writing, you cannot format
 text afterwards. You can move with left and right arrows (only Opera on windows)
 up and down are not implemented.
 The current GUI is a simple auto-generated set of buttons that purposefully
 exposes the inner logic of walter. When more things work a real GUI needs to
 be built.
 MAIN CHALLENGES
 Altough the DOM is a great API, listening to keyboard and especially mouse
 events is not very standardised. Early experiences suggest that keystrokes
 will not be a problem, mouse-events might need some imagination (not tried
 yet). Non-characters (arrows, delete...) have different keycodes in
 different browsers, which will be a major challence.
 BROWSERS
 Walter works on the following browsers:
 IE4, NS4
 Will not work, we use DOM.
 IE5 and above
 As for JavaScript support, this will work on IE5 and above,
 but at least IE6 will crash after a few keystrokes. It simply
 can"t take the pounding
 Mozilla and derivatives
 Works great
 Opera
 Works great
 Arrows and some other keys have different keycodes in Opera than in
 Moz and IE
 Konqueror 3.1.0
 Doesn"t seem to do anything. Have not checked why this is.

  Inline elements are divided into *empty* elements
  and *inline* elements. "Empty elements" are those
  like <img> and 
. It"s an error to try to insert
  anything into an empty element (and the browser will
  let you know...). "Inline elements" are all the other
  inline elements like , , <a>...
  Block elements are divided into *paragraph* and *block*
  elements of which the latter are not yet supported.

Paragraph elements are
,
and so forth. Everything else are block elements. A lot of logic depends on a rule that the cursor will always be inside exactly one paragraph element (a <p> for instance). Obviously (it follows from the above rule and the HTML standard) all inline and empty elements must also be inside exactly one such element. You can add an element that is not supported simply by adding appropriate lines below. All creation and manipulation of elements relies on information from this elements-object. Even the GUI buttons are currently created automatically from that.
