前言

之前一直苦恼 Linux 下没有一款好用的带 Live Preview 功能的 MarkDown 编辑器,也尝试过 ReText,不过它的 Live Preview 默认似乎就没有用什么 CSS,看着不舒服。

今天偶然发现原来 ReText 也是支持自定义 CSS ,支持代码高亮的。

一.添加语法高亮

ReText支持语法高亮,但需要在在Markdown extensions框里添加字段:codehilite,同时,需要下载安装高亮支持模块python-pygments

apt-get install python-pygments

二.添加数学公式

在Retext下想使用数学公式,首先应该先安装MathJax,同时需要在在Markdown extensions框里添加字段:mathjax

apt-get install libjs-mathjax

三.添加自定义CSS

stylesheet file: 选择css样式文件即可

附一份css样式(出处不详):
