如果像我一样，你在Windows上运行gVim，那么你的.vimrc文件可能是另一个“示例”Vimscript文件，它会自动设置文本文件的文本宽度(在我的例子中是78)。

我在Vi和Vim Stack Exchange站点上回答了一个类似的问题——如何停止gVim在第80列包装文本:

In my case, Vitor's comment suggested I run the following: :verbose set tw? Doing so gave me the following output: textwidth=78 Last set from C:\Program Files (x86)\Vim\vim74\vimrc_example.vim In vimrc_example.vim, I found the relevant lines: " Only do this part when compiled with support for autocommands. if has("autocmd") ... " For all text files set 'textwidth' to 78 characters. autocmd FileType text setlocal textwidth=78 ... And I found that my .vimrc is sourcing that file: source $VIMRUNTIME/vimrc_example.vim In my case, I don't want textwidth to be set for any files, so I just commented out the relevant line in vimrc_example.vim.

使用:set nowrap ..效果好极了!

正确的是，set nowrap将允许你粘贴一个长行，而不需要vi/vim添加换行符，但这样行就不会被视觉上的换行以方便阅读。相反，它只是一个长长的行，你必须滚动。

要使行在视觉上换行但不插入换行符，请设置wrap(这可能是默认设置，因此不需要设置)并设置textwidth=0。

在某些系统上，textwidth=0的设置是默认的。如果您发现情况并非如此，请将set textwidth=0添加到您的.exrc文件中，以便它成为所有vi/vim会话的用户默认值。

我个人认为:

包装, 设置linebreak 设置breakindent 设置showbreak =ͱ。

这里做一些解释:

wrap option visually wraps line instead of having to scroll horizontally linebreak is for wrapping long lines at a specific character instead of just anywhere when the line happens to be too long, like in the middle of a word. By default, it breaks on whitespace (word separator), but you can configure it with breakat. It also does NOT insert EOL in the file as the OP wanted. breakat is the character where it will visually break the line. No need to modify it if you want to break at whitespace between two words. breakindent enables to visually indent the line when it breaks. showbreak enables to set the character which indicates this break.

参见:h <关键字>在vim中获得更多信息。

注意，如果您采用这种方法，则不需要修改textwidth和wrapmargin。

set formatoptions-=t保持视觉文本宽度，但不会在插入模式中添加新行。

Use

:set wrap

可视化地换行，即该行仍然是一行文本，但Vim将其显示为多行。

Use

:set nowrap

将长行显示为一行(即，您必须水平滚动才能看到整行)。
