Designing <richtext>

I am designing <richtext> behavior for htmlayout/sciter… So far I like the way it allows to edit the text.

There are interesting usability problems bubble up sometimes… Let’s say you have following document: 

<body>
  <pre>
     ....
  </pre>
  <table>
     ....
  </table>
</body>

And now imagine that you need to insert some text (paragraph) between the table and that pre block. Or insert paragraph (<p>) at the beginning of the document – before the <pre>…

I do not know any WYSIWYG HTML editor that allow to handle such operations.

So I have invented “horizontal caret” that marks start-block-position. Enter key in that position causes new paragraph to be inserted.

Here is an example of such caret – blinking black bar in top-left corner of the pre element:

richtext, horizontal caret

XML/HTML tokenizer (or pull parser?)

Here is source code of my XML/HTML tokenizer: xh_scanner_demo.zip

See my article on CodeProject: HTML/XML scanner/tokenizer

Does not allocate any memory while parsing, extremely fast and compact.
