<p>This plugin adds an advanced code editor to the post content box on post.php and post-new.php. A third tab is added alongside Visual and HTML modes and you can toggle between the three.</p>
<p>NOTE: Visual Mode tends to eat up most/all of any special formatting. If you want to use ACE I’d suggest disabling Visual mode completely. You can do this easily yourself under Users -> Your Profile -> ‘Disable the visual editor when writing’. You can also do it for all users and for specific post types only. See the accompanying file no-visual.php for an example.</p>
<p>Not all features work in Internet Explorer v8 and earlier.</p>
<p>This does not work in full screen mode. Yet.</p>
<h4>Features</h4>
<ul>
<li>Syntax highlighting</li>
<li>Tabbing</li>
<li>Line numbers</li>
<li>Auto closing of tags and quotes</li>
<li>Line highlighting</li>
<li>Default theme is TextMate</li>
<li>Fixed-width, soft wrap, adjustable height</li>
<li>Remembers your last used mode and loads it up on initial page view</li>
</ul>
<p><a href="http://ace.ajax.org/" rel="nofollow ugc">ACE Editor</a> can do quite a bit more. If you have integration ideas, let me hear about it</p>
<h3>Todo</h3>
<ul>
<li>make height of editor consistent when toggling between modes</li>
<li>deal with auto_p? (might help preserve formatting from Visual mode)</li>
<li>make it work in full screen mode</li>
<li>allow users to set their ACE preferences on their profile screen</li>
</ul>
