Recently I was appointed to become the maintainer of the zen-coding plugin for Emacs after I submitted several patches for it. What the patches do:
- #id and .classes can now be used without specifying the tag name (it will default to div).
- Automatically self-close self-closing tags (br, img, input) except if it has child(ren). The latter is useful when you are writing xml that happens to have tags named br/img/input.
- Support for quoted attribute value (E attr=”value”), useful if the attribute value contains special characters, such as parentheses.
- Tag expander syntax support (E+) automatically expands tags that have obvious children (table, ol, ul, dl). For example ul+ will be expanded to <ul><li></li></ul>.
- Improved formatting (indentation and newlines).
- Added filters support. Implemented filters (other than html) are:
- c (comments for elements with #id or .classes).
- haml.
- hic (clojure’s hiccup).
- e (escape xml-unsafe characters < > and &).
If you are writing html/haml/hiccup using Emacs, you might find the plugin useful. Check it out. Contributions are welcomed.
PLEASE READ BEFORE SHARING 
zen-coding for emacs is great, and has become a vital part of my web coding environment.
There is one feature I wish it had. I’d code it up myself if I had a clue when it comes to lisp:
When I’m marking up documents with any amount of complexity, I put comments at the end of all of my major containers, so I know where I am.
So my ‘#cart’ or ‘#header.col’ will have a comment saying “cart ends here”. I do this a lot.
It’d be great if zen-coding for emacs had a switch, so that when activated, the author could indicate that they want the end of the container commented.
not bad idea, I have seen that a lot, like in wordpress…
