Next generation Wysiwyg API: Edit like a rock star!

smk-ka and me worked on the next generation of Wysiwyg API today. Stunning results! Which are still compatible with D6 and D5.

Known issues of the past:

• Client-side editors attach to textareas, which do not support input formats at all. As a result, either all your formattings are not rendered, or you are faced with editors in places where no editor was ever considered, destroying your configuration or PHP code.
• When working with a client-side editor, you need to ensure that you have set the proper input format, so the entered markup is not removed from the output. Failing to do so means to edit a content again, just to change the input format.
• Disabling a client-side editor on a textarea the editor attached to, leads to missing default behaviors of Drupal, such as the grippie to resize the textarea. A tiny editing window and ugly scrollbars instead.

The solution:

With the patch in Attach client-side editors to input format enabled textareas only, which is about to be committed:

• Client-side editors are no longer dumb scripts.
• Editors are associated with input formats, making it possible to associate "BBedit" editor with a "BBcode" input format. A lightweight TinyMCE profile with "Filtered HTML". A full blown FCKeditor with "Full HTML".
• Not every input format needs an editor. PHP code for example. If such an input format is selected when the page loads, no editor is attached to the particular textarea.
• Editors are able to be switched if the input format is changed.
• Regular behaviors in Drupal core are restored when no editor is attached. Resizable textareas are back again.

Remaining todos:

• Introduce a GUI to associate an editor or editors to input formats. Not sure whether more than one makes sense. If not, we can remove the whole access permission system from Wysiwyg API's profiles.
• Refactor JavaScript settings, so we can store the configuration for different editors simultaneously and support different editors (input formats) on the same page.
