我使用 vim/gvim 作为我的默认文本编辑器。
当我编辑没有语法高亮的纯文本文件时，如果结束行上的最后一个字符是逗号，则按下回车键时它会自动添加缩进。
此缩进的长度是可变的，将光标置于上一行的第一个单词下方。
例如按键序列
a <space> b <enter> a <space> b , <enter> a <space> b
产生这个
a b
a b,
a b
如果我:setlocal filetype?得到了filetype=text。

我不想让 vim 巧妙处理纯文本文件。如何关闭此功能，但保留其他文件类型的自动/智能缩进？
答案1
这是由启用的'cindent'选项引起的。我尝试摆弄'cino'选项，但显然它不受此影响（但我对这些没有经验）。
我认为您应该禁用纯文本文件的 c-indenting，而只使用智能缩进和自动缩进。
由于您对这些文件进行了文件类型检测（text），只需添加以下内容：
将相应setlocal nocindent命令输入~/.vim/ftplugin/text.vim。 （这要求您有:filetype plugin on。）
或者，您可以:autocmd FileType text setlocal nocindent直接在中定义一个~/.vimrc，但是一旦您进行了许多自定义，这往往会变得难以处理。
