整理翻译过程中用到的正则表达式。

处理用pandoc转换而来的markdown

用途：把这个网页转换为markdown文件供BasicCAT翻译。

处理以下内容：

[activation]{#0010}
-------------------

A short communication between an installed program and the
manufacturer’s website. The program sends your serial number and a few
anonymous details about your computer. The website checks that you own a
license or that you are just starting a free trial, and returns a code
to authorize the program to run on your computer.

  1. 去掉开头和结尾都是-的行，使用以下表达式进行匹配

    ^-+$

  2. Markdown的段落需要用两个换行进行区分，段落可以是一行或多行文字。用pandoc转换后的markdown，段落里有多行文字。而我打算用BasicCAT以txt形式打开markdown文件，所以得把段落中的换行替换掉，这个操作英文叫做reflow。

    1. 把连续的换行符换成一个标记

      (\r\n){2,}，替换为“段落标记”

    2. 去掉所有换行符为空格。markdown中段落里的换行相当于空格，不替换单词间会缺少空格

    3. 把“段落标记”替换回两个换行

  3. 去掉锚点，把[activation]{#0010}改为### activation

    \[(.*?)\]\{#\d+\}，替换为### \1

  4. 去掉链接，把[CAL license](#0140)改为CAL license

    \[(.*?)\](#\d+)，替换为\1

结果：

### activation

A short communication between an installed program and the manufacturer's website. The program sends your serial number and a few anonymous details about your computer. The website checks that you own a license or that you are just starting a free trial, and returns a code to authorize the program to run on your computer.
