About Zencoding
Description here and here.
I’ll quote the blog:
zen-coding includes an entirely new angle to writing markup, and it facilitates the feature by letting you write HTML based on CSS selectors. It’s so simple it’s confusing at first. I think it’s best explained by doing a quick before and after. If you were to type:
div#name.one.two
and follow that with the zen-coding plugin keystroke (CMD+E in TextMate), the plugin will reformat the line as:
<div id="name" class="one two"></div>
See the EmacsWiki for more background on this mode.
Screenshots and videos
Installation
Just make sure zencoding-mode.el is in your load-path, if you
extracted zencoding-mode to a directory:
(add-to-list "~/emacs.d/zencoding-mode")
And then just require as normal:
(require 'zencoding-mode)
Usage
Enable it by running M-x zencoding-mode. You probably want to add it
to auto-load on your sgml modes:
(add-hook 'sgml-mode-hook 'zencoding-mode) ;; Auto-start on any markup modes
Good to go: place point in a zencoding snippet and press C-j to expand it (or alternatively, alias your preferred keystroke to M-x zencoding-expand-line) and you'll transform your snippet into the appropriate tag structure.
