Brett's AutoTag bundle works with WordPress 2.1 and its Ultimate Tag Warrior plugin to present a window (pictured) containing all the tags you've used on your WordPress blog; perfect for tagging your posts on the fly and helping you to keep your tag system tidy. But one might ask: what is an AutoTag plugin without some auto action, right? AutoTag can tag your post for you by scanning what you've written and comparing it against your tag database. Simply type 'auto' and press tab to watch the magic happen. And as if that wasn't enough, AutoTag even has a command for suggesting new tags, again based on a scan of your post's content or even Yahoo's Tag Suggestion feature. With all this clever 'auto' functionality going on, let's just hope Brett's next plugin isn't called 'AutoBlog,' or we might all be in trouble.
To give your TextMate + WordPress workflow a tagging boost, you simply need to install a UTW-RPC plugin for WordPress (available with the AutoTag bundle) in order for TextMate to access your database of tags. Setup is really simple, but be sure to download the version of AutoTag that corresponds to the version of TextMate you're running, i.e. - Cutting-Edge or the regular version available from the Macromates site.
The AutoTag bundle and UTW-RPC WordPress plugin are open source and available from Circle Six Design.
