现在用erb改写一下:
#!/usr/bin/ruby
#encoding:utf-8
require "erb"
temp = ERB.new <<HTML_DOC
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
<style type="text/css">
<% types = %w[none disc circle square decimal decimal-leading-zero lower-roman \
upper-roman lower-alpha upper-alpha lower-greek lower-latin upper-latin \
hebrew armenian georgian cjk-ideographic hiragana katakana hiragana-iroha \
katakana-iroha] %>
<% types.each do |t| %>
ul.<%=t%> {list-style-type: <%=t%>}
<% end %>
</style>
</head>
<body>
<% types.each do |t| %>
<ul class=<%=t%>>
<li><%=t%> 类型</li>
<li>茶</li>
<li>可口可乐</li>
</ul>
<% end %>
</body>
</html>
HTML_DOC
puts temp.result #或者temp.run
之后在终端加运行权限:chmod u+x e.rb,然后执行: ./e.rb >index.html,哦鸟!
