在VIM中,如何将一条很长的线分成多行？

Question

假设我在VIM编辑器中有超长行(比如大约300多个字符).如何将其分成多行,使单词边界大致突破80个字符？

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非常容易这样做(在字边界处断线).

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

我建议你检查:help gq和:help gw.

设置textwidth(tw)还会在键入时超出时自动换行.它也被使用gq,但如果禁用gq中断窗口大小或79取决于哪个先出现.

:set tw=80

通过设置格式选项以包括文本宽度,vim将在tw设置时自动中断.

:set fo+=t

Answer 2

首先设置你的vim,以便它理解你想要80个字符:

:set tw=80

然后,暮光之城:

V

并使vim重新格式化:

gq

Answer 3

这与VIM并不真正相关,但您可以使用fmt程序

$ fmt myfile

Answer 4

对于实线文本,在正常模式下使用v突出显示区域,然后按

:s/\v(.{80})/\1\r/g

这将在每个第80个字符的末尾添加换行符.

:s/       replaces within the current select
\v        uses regular expressions
(.{80})   selects 80 characters & placed them into group one
\1\r      replaces group one with group one and a newline

Answer 5

如果你在*nix上,你可能已经fold有了.

选择您想要使用的区域v,然后您可以使用以下方法中断宽度为80的空格:

!fold --spaces --width=80

这与使用完全相同gq.

但是,如果您只想在字符80处中断而不限于空格,则可以使用:

!fold --width=80

如果你只需要一次按键就可以设置一个映射 - 我已经用过了

vmap <f1> !fold --width=80<CR>

Answer 6

要在完整文档中拆分长行而不删除现有的换行符，请使用：

:set formatoptions+=w
:set tw=80
