This button removes the HTML formatting tags; abbr, acronym, address, b, big, blockquote, cite, code, del, em, font, i, kbd, pre, s, small, span, strike, strong, sub, sup, u.

It processes the selected text and replaces it with the format-free text.

BBCode to HTML conversion is usually done on server side thus at least one server request is required to display the result. BBCode2HTML is a JavaScript function implemented to do the conversion on client side so the result can be previewed without hitting the server. Supported BBCode tags and a live preview example can be found at BBCode Editor page.

Smileys module provides an input filter converting text smileys into images. It allows creation or import of new smileys.

The smiley button dynamically gets the list of smileys and displays them in a dialog for users to choose. You should be using ajax preview in order to see the images in preview mode. js: E.prvAjax();

Update: BUEditor 6.x-2.x or later versions come with a predefined BBCode editor. Use that one instead of the editor below.

Bbcode module provides a filter to use BBCode tags in Drupal posts. Although BUEditor allows usage of BBCode tags by default, its most important features such as instant preview or IMCE integrated image and link dialogs works for only HTML tags. This is because any other tag system requires extra process to be converted into HTML.

Below is a re-implementation of default buttons that allow insertion and instant preview of BBCode tags. The code in the demo contains most of the tags that are supported for previewing.

BUEditor, sometimes, is criticized to have a too simple interface having ugly buttons. Having no counter-arguments, I can only show how BUEditor can be themed in order to achieve the desired look.

The below is a demonstration of a themed interface of BUEditor's default editor, which has become very hard to be recognized as BUEditor. The buttons and the style is borrowed from the popular WYSIWYG editor: TinyMCE. Hopefully, its interface is not criticized too much.

JsAutoP is the JavaScript equivalent of the PHP function described at Matthew Mullenweg's website. The PHP function is a part of Wordpress code, which is used to convert new lines to HTML line breaks and paragraphs inside user entries. A similar function is also used in Drupal for the same purpose.

TMCE is my interpretation of how TinyMCE WYSIWYG Editor should be integrated into Drupal.
This project will not be officially available among Drupal projects since there are already modules (tinymce and tinytinymce) managing the same task.

Inline module button provides a user interface for adding inline files and images.

It opens an inline syntax dialog requesting three properties; inline type(inline, file, attachment), file name or id, and title.
If the selected text is a proper inline syntax, properties are extracted for editing.

A demo is available for testing. Note that you won't see here how inline syntax is converted to a link or an image. You must use drupal's preview in your own site.

Imagecache module button provides a user interface for adding images provided by imagecache presets.

It allows users select one of the imagecache presets that will handle the selected image. If IMCE is installed, the image URL can be retrieved from IMCE interface, otherwise the user specifies it manually.

A demo is available for testing.

Quick Table button provides a user interface for adding html tables into the content.

It has a very simple interface that allows easy creation of tables of any size by a single mouse click.

A demo is available for testing.
