之前默认的代码块样式实在是不堪入目，颜色排版等问题突出，所以要好好捣鼓一下。

采用的是pygments，大名鼎鼎了，有名气用起来就有底气，重要的是支持的色彩搭配确实很赞。

1.安装

首先本地先安装好支持库，然后开发编辑的时候，就可以选各种主题了。

1
sudo apt-get install python-pygments

如果你没有装redcarpet的gem包，请安装:

1
sudo gem install redcarpet

2.配置

在_config.yml中配置如下：

1
2
3
4
markdown: redcarpet
highlighter: pygments
redcarpet:
    extensions: ["fenced_code_blocks", "tables", "highlight", "strikethrough"]

3.生成样式文件并加入你的网站引用

1
pygmentize -S default -f html > your/path/pygments.css

主题有很多，['monokai', 'manni', 'rrt', 'perldoc', 'borland', 'colorful', 'default', 'murphy', 'vs', 'trac', 'tango', 'fruity', 'autumn', 'bw', 'emacs', 'vim', 'pastie', 'friendly', 'native']

1
2
# -S 参数后面就是主题名称
pygmentize -S monokai -f html > your/path/pygments.css

生成的pygments.css文件或者内容自己在网站头部引用：

1
<link rel="stylesheet" href="/your/path/pygments.css">

4.jekyll代码块高亮

代码块放在两个标签之间，highlight c linenos=true 和 endhighlight，其中的linenos是行号显示，加上table值可以copy代码的时候忽略行号。

5.打完收工

以下是展示，可能c的高亮支持不太好，以后可以继续优化。
