I personally tend to hate WYSIWYG editors. They take time to load and just love plain old HTML, so I just disable the editor entirely. However, I would like to have HTML from the database to be prettyfied or beautified or ... well, loooking sexy for the time of editing with indents, newlines, etc. Any module out there that does that?
From Ace's website:
I'm not aware of any other source code wysiwyg editor supported by wysiwyg.module.
You're looking for HTML Tidy module.
This module tidies Drupal's HTML output with HTML Tidy by optionally sanitizing it when it is saved or when it is displayed, like a traditional input formatter. Missing and mis-ordered tag components are replaced and reordered automatically so that user input doesn't break site structure with open tags and the like.
User interface configuration supports:
Code indenting: Automatically format HTML for easier reading, or strip indenting for proper parsing and display in the less compliant browsers. Word wrapping: Automatically wrap lines in an intelligent fashion once they get to a specified length Info/Warning/Error information: Optionally appended to pages and includes details about the wrong HTML attributes and W3C validation info.
