Update - 08/27/2013: Revised table for Tab Override v4.0.0 and tabIndent.js v0.1.8
A few years ago, I was trying to format some HTML in the WordPress HTML editor and was frustrated by the lack of tab key support. The normal behavior of the tab key is to move the focus to the next focusable element on the page. Since this is also true for textarea elements, pressing the tab key in a textarea will move the focus away from it. Users have come to expect the tab key to function this way and changing it would most certainly be confusing. However, when the purpose of the textarea is to input code, it seems more natural for it to behave more like a simple text editor.
Recently, some new projects have appeared that address the same issue. Two of the more popular ones are tabIndent.js and Behave.js. The projects are similar in a lot of ways, but take slightly different approaches and have different feature sets. The following is a comparison of the tabbing/indenting-related features of Tabby, Tab Override, tabIndent.js, and Behave.js:
The Tab Override WordPress plugin was just updated to version 3.1. This release includes a new option to add a tabs on/off button to the
HTML editor toolbar, allowing you to quickly enable or disable the plugin while editing a post or page. This release also includes several important bug fixes.
To get complete details and download the latest version, visit the
Tab Override page at the WordPress Plugin Directory. You can try out the latest version
of the jQuery plugin on the demo page.
A common problem with WordPress themes and plugins is users making custom modifications to them only to have their work erased when the theme or
plugin is updated. To avoid this, you can create a child theme that extends the original theme or a plugin that modifies another plugin. Tab Override version 3.0
provides a global object and hooks just for this purpose.
The $tab_override Global Object
As soon as the plugin code is executed, a global object named $tab_override is created. This object is an instance of the Tab_Override class. You can use this
object to check if the Tab Override plugin is installed and activated. Normally to check for another plugin you would do something like this: Continue reading
The Tab Override WordPress plugin was updated to version 3.0 today. This is an almost complete rewrite of the plugin and includes several new features, notably:
- a new auto indent feature
- translation support
- the addition of tab_override_init and tab_override_add_scripts hooks
In addition, there are enhancements to both security and performance as well as a new uninstall procedure and much improved documentation.
Most of the code was refactored into a class. Since some PHP 5 features were utilized, PHP 4 is no longer supported.
This version of the plugin also includes support for the upcoming WordPress 3.2 release and the fullscreen editor mode.
