在 Vim 中“按段落”对文件进行排序

Question

给定一个看起来像这样的文件：

Crab
  some text that doesn't need sorting.
  more textual descriptination
Albatross
  some text or other
  perhaps a list that needs no sorting:
    1. a
    2. bee
Dolphin
Pterodactyl
  long story about this particular animal.

我如何告诉 Vim（第 7 版）按动物名称的字母顺序对这个文件进行排序？不可能的？否则如何对这个文件进行排序？

Answer 1

是的，你可以在 vim 中做到：

:%s/$/$/
:g/^\w/s/^/\r/
:1del t | $put t
:g/^\w/,/^$/-1join!
:sort
:%s/\$/\r/g
:g/^$/d

输出

Albatross
  some text or other
  perhaps a list that needs no sorting:
    1. a
    2. bee
Crab
  some text that doesn't need sorting.
  more textual descriptination
Dolphin
Pterodactyl
  long story about this particular animal.

您应该使用特殊字符来表示 EOL（除了$）！
