vim - 在 VIM 中，如何将一行很长的行分成多行？

Question

假设我在 VIM 编辑器中有一个超长的行(大约 300 多个字符)。我如何将其分成多行，以便单词边界大致在 80 个字符处断开？

示例:

This is a really long line This is a really long line This is a really long line This is a really long line This is a really long line This is a really long line This is a really long line This is a really long line This is a really long line This is a really long line This is a really long line

至

This is a really long line 
This is a really long line
This is a really long line
This is a really long line
This is a really long line
This is a ...

Answer 1

Vim 做到这一点非常简单(在单词边界处换行)。

gq{motion} % format the line that {motion} moves over
{Visual}gq % format the visually selected area
gqq        % format the current line
...

我建议您查看 :help gq 和 :help gw。

此外，设置文本宽度 (tw) 将使您在输入过程中超出时自动换行。它也用于 gq 中，但如果禁用 gq 则会破坏窗口大小或 79，具体取决于哪个先出现。

:set tw=80

通过设置格式选项以包含文本宽度，vim 将自动在 tw 设置处中断。

:set fo+=t
