QuickTag is a project mainly written in PHP, it's free.
A parser that makes HTML slightly quicker to write
QuickTag
This is a very simple parser for a modified HTML
The idea was to bring HTML class and id attributes inline with CSS and jQuery selectors, so instead of:
<div class="class-one class-two" id="my-id"
You can use: <div#my-id.class-one.class-two
It's not a huge difference, but its something that's always bothered me, and it only took half an hour to write the parser, so I thought I'd share it.
index.php gives a very simple usage example.
