Hacker主题——添加mathjax支持

1. 在主题的_config.yml中，添加第4行的内容

_config.yml

# google analytics
googleTrackId:

mathjax: true

2. 在主题目录下layout/components/head.ejs，末尾添加第5-7行内容

head.ejs

<link rel="alternate" href="<% if (theme.rss){ %><%- theme.rss %><% } else { %><%- config.root %>atom.xml<% } %>" title="<%= config.title %>" type="application/atom+xml">
  <link rel="stylesheet" href="<%- config.root %>css/style.css" media="screen" type="text/css">
</head>

<% if(theme.mathjax) {%>
    <%- partial('mathjax')%>
<% } %>  

3. 接着在指定目录下新建文件layout/components/mathjax.ejs,输入以下内容

<!-- mathjax config similar to math.stackexchange -->

<script type="text/x-mathjax-config">
  MathJax.Hub.Config({
    tex2jax: {
      inlineMath: [ ['$','$'], ["\\(","\\)"] ],
      processEscapes: true
    }
  });
</script>

<script type="text/x-mathjax-config">
    MathJax.Hub.Config({
      tex2jax: {
        skipTags: ['script', 'noscript', 'style', 'textarea', 'pre', 'code']
      }
    });
</script>

<script type="text/x-mathjax-config">
    MathJax.Hub.Queue(function() {
        var all = MathJax.Hub.getAllJax(), i;
        for(i=0; i < all.length; i += 1) {
            all[i].SourceElement().parentNode.className += ' has-jax';
        }
    });
</script>

<script type="text/javascript" src="http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML">
</script>

大功告成！
