阻止vim删除空行上的缩进 [英] stopping vim from removing indentation on empty lines

问题描述

当光标放在带有空格字符的一行的末尾时，当我按Enter键时，vim将删除该空格.我觉得这很烦人，因为它破坏了我选择缩进相同级别代码的脚本.如何防止vim执行此操作?

When the cursor is placed at the end of a line containing nothing but withspace characters, vim will, when i press enter, remove that whitespace. I find this irritating, as it breaks my script for selecting code that are indented to the same level. How can I prevent vim from doing this?

在我的.vimrc( http://bjuhn.com/randomstuff/vimrc )中，我有以下内容:

In my .vimrc (http://bjuhn.com/randomstuff/vimrc) I have the following:

filetype plugin on
set copyindent

也就是说，我没有使用任何可识别语法的自动缩进，因为我还没有找到可以自动完成所有功能的缩进.

that is, I am not using any syntax-aware auto-indention, as I have yet to find one that does everything to my liking.

推荐答案

Vim Wiki 建议这个:

inoremap <CR> <CR>x<BS>

因为即使在行中输入了一些文本，即使删除了缩进，也不会删除缩进.

because the indenting is not removed if some text has been entered on the line, even if it has been deleted.

完整解决方案中仅缺少几处.您还需要重新映射o和O以及用于添加线的其他任何内容:

Just a couple of pieces missing from a full solution. You also need remaps for o and O and whatever else you use to add lines:

inoremap <CR> <CR>x<BS>
nnoremap o ox<BS>
nnoremap O Ox<BS>

相同的想法，但是刚接触vim的人可能不会很快发现它.

Same idea but people newer to vim might not figure it out quickly.
