octopress分类中使用二级目录

1.修改plugins/category_list_tag.rb为

# encoding: UTF-8
module Jekyll
	class CategoryListTag < Liquid::Tag
		def render(context)
			html = ""
			pre = ""
			divout = 0
			categories = context.registers[:site].categories.keys
			categories.sort.each do |category|
				posts_in_category = context.registers[:site].categories[category].size
				category_dir = context.registers[:site].config['category_dir']
				cats = category.split(/~/)
				if cats.size > 1 and cats[0] == pre
					if divout == 0
						html << "<div id='#{pre}' class='divclass'>"
						divout = 1
					end
					html << "<li><a href='/#{category_dir}/#{category.to_url}/?opendiv=#{pre}'>#{cats[1]} (#{posts_in_category})</a></li>\n"
				else
					pre = cats[0]
					if divout > 0
						html << "</div>"
						divout = 0
					end
					html << "<li class='category'><a href='##' onmousedown=showDiv('#{pre}')>#{category} </a><a href='/#{category_dir}/#{category.to_url}/'>(#{posts_in_category})</a></li>\n"
				end
			end
			if divout > 0
				html << "</div>"
				divout = 0
			end
			html
		end
	end
end

Liquid::Template.register_tag('category_list', Jekyll::CategoryListTag)

2.修改source/_includes/custom/asides/category_list.html为：注意去掉’\‘

<section>
<h1>Categories</h1>
<head>
<style type="text/css">

.divclass
{
	display:none;
	font-size:12px;
	position:relative;
	left:0px;
	top:0px;
	padding:0px 30px 0px 30px;
}
</style>
<script language="javascript" type="text/javascript">

function showDiv(divName)
{
	if (document.getElementById(divName).style.display == "block")
		document.getElementById(divName).style.display = "none"; //隐藏层
	else
		document.getElementById(divName).style.display = "block"; //显示层
}

function GetRequest(name) {
	var url = location.search; //获取url中"?"符后的字串
      if (url.indexOf("?") != -1) {
		var str = url.substr(1);
		strs = str.split("&");
		for(var i = 0; i < strs.length; i ++) {
			if (name == strs[i].split("=")[0])
			return unescape(strs[i].split("=")[1]);
	      }
      }
      return null;
}
</script>
</head>
<body>
<div id="menu">
<ul>
{\% category_list \%}
</ul>
</div>
</body>
</html>

<script language="javascript" type="text/javascript">
var divname = GetRequest("opendiv");
if (divname != null)
	showDiv(divname)
</script>
</section>

3.使用二级标签的时候先写一个一级标签，写一个一级~二级标签，例如：

 categories:
 - hello
 - hello~hi

kk Blog —— 通用基础

date [-d @int|str] [+%s|"+%F %T"]
netstat -ltunp
sar -n DEV 1

1.修改plugins/category_list_tag.rb为

2.修改source/_includes/custom/asides/category_list.html为：注意去掉’\‘

3.使用二级标签的时候先写一个一级标签，写一个一级~二级标签，例如：

4.add

后来又改成了三级目录，显示调整，单列时间分类等。具体去看源码对应文件。
