Haml&Radius 不错
Hamlhttp://haml.hamptoncatlin.com/
今天花了点时间读了遍Reference:http://haml.hamptoncatlin.com/docs/rdoc/classes/Haml.html
对haml的印象彻底改变了，说句老实话，之前懒得看这个东西，一直认为它没啥意思，今天才发现，使用他，代码简洁多了，而且很容易上手，成本比较低。
!!! XML!!!%html%head/%body #main .articles .article.title Hello World .article.date 2008-8-12 14:10:58 .article.content Content goes here
生成如下的代码：
<?xml version='1.0' encoding='utf-8' ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head /> <body> <div id='main'> <div class='articles'> <div class='article title'> Hello World </div> <div class='article date'> 2008-8-12 14:10:58 </div> <div class='article content'> Content goes here </div> </div> </div> </body> </html>
在haml中，我们还可以直接写textile文本，如
#main.articles .article.title :redcloth h2. Hello World .article.date :markdown _2008-8-12 14:10:58_
生成
<div id='main'> <div class='articles'> <div class='article title'> <h2>Hello World</h2> </div> <div class='article date'> <p><em>2008-8-12 14:10:58</em></p> </div> </div> </div>

来个更复杂点的内容(来自Radiant的application.html.haml)：
!!!%html{html_attrs}%head %meta{"http-equiv"=>"Content-type", :content=>"text/html; charset=utf-8"}/ %title= @page_title || default_page_title - @stylesheets.uniq.each do |stylesheet| = stylesheet_link_tag stylesheet - @javascripts.uniq.each do |javascript| = javascript_include_tag javascript / %script{:type=>"text/javascript", :src=>"/admin/javascripts/pngfix.js"} - if @content_for_page_scripts = javascript_tag @content_for_page_scripts - if @content_for_page_css %style{:type => "text/css"}= @content_for_page_css%body #page #header #site-title= link_to_unless_current title, admin_url #site-subtitle= subtitle - if logged_in? #navigation= links_for_navigation %hr{:class=>"hidden"}/ #main - if flash[:notice] #notice %p= flash[:notice] - if flash[:error] #error %p= flash[:error] #content = find_and_preserve(yield) %hr{:class=>"hidden"}/ #footer %p This site was made with Ruby and is powered by %a{:href=>"http://radiantcms.org"} Radiant CMS version = Radiant.loaded_via_gem? ?

Radius
http://radius.rubyforge.org/
Radius 是一个强大的基于标签的模板语言。
我们引用下文档中的示例：
require 'radius'context = Radius::Context.new do |c| c.define_tag 'hello' do 'Hello world' end c.define_tag 'repeat' do |tag| number = (tag.attr['times'] || '1').to_i result = '' number.times { result << tag.expand } result endend
在页面中，我们编写如下代码：
<radius:repeat times="3">* <radius:hello />!</radius:repeat>
生成
<div class="quote_title">引用
