如何“重写"密码?现有的vim键绑定? [英] How to "rewrite" existing vim key bindings?

问题描述

我想分配 CTRL + L 进入下一个标签页(:tabnext).我将其放置在~/.vimrc:

I want to assign CTRL+L to go the next tab (:tabnext). I placed it at ~/.vimrc:

nmap <c-l> :tabnext<CR>

它工作正常，但是当我在多个窗口上拆分屏幕时，我遇到了无法正常工作的情况.似乎 CTRL + L 与重新绘制屏幕"冲突.默认情况下分配的操作.例如，当我在中心窗口上按 CTRL + L 时，我什么也没得到(请参见屏幕截图):

It worked fine, but I faced with a case when it doesn't work when I split screen on several windows. It seems that CTRL+L conflicts with "redraw screen" action assigned by default. For example, when I press CTRL+L on the center window I get nothing (see the screenshot):

但是，当我在左右两个窗口上按相同的按钮时，它仍然可以正常工作. 我认为我需要重写"默认操作，不是吗?

However when I press the same on either left or right windows it works fine.. I think I need to "rewrite" the default action, doesn't it?

我在终端上使用vim.

推荐答案

如果没有记错的话，中间的窗口是netrw(Vim的文件管理标准插件).它不是一个自定义插件，但仍然是一个插件.

The window in the middle, if I am not mistaken, is netrw (Vim's standard plugin for file management). It is not a custom plugin, but it is a plugin nevertheless.

如果您查看:help netrw-ctrl-l，您会发现它不仅是重绘，而且还会刷新目录.因此，它是从插件映射的，仅覆盖了netrw Windows的默认ctrl-l映射.

If you take a look at :help netrw-ctrl-l, you will see that it is not just a redraw - it also refreshes the directory. So it is mapped from the plugin, overriding the default ctrl-l mapping for netrw windows only.

如果在该窗口中执行:verbose nmap <c-l>，您将确切地看到它的定义位置:在Vim安装的autoload/netrw.vim文件中.看那里，我们发现以下代码段:

If you execute :verbose nmap <c-l> in that window, you will see exactly where it is defined: in autoload/netrw.vim file in your Vim installation. Looking there, we find this snippet:

if !hasmapto('<Plug>NetrwRefresh')
 nmap <buffer> <unique> <c-l> <Plug>NetrwRefresh
 imap <buffer> <unique> <c-l> <Plug>NetrwRefresh
endif

这说，如果<Plug>NetrwRefresh未绑定任何东西，则绑定<c-l>.这提供了一个简单的解决方案:由于netrw.vim与其他所有内容一样，都在.vimrc之后加载，因此，如果您将这些映射定义为其他键，则不会将它们分配给<c-l>，并且不会覆盖您的映射.因此，只需在您的.vimrc:

Which says, if <Plug>NetrwRefresh is not bound to anything, then bind <c-l>. This presents an easy solution: since netrw.vim is, like everything else, loaded after .vimrc, if you define those mappings to some other key, they won't be assigned to <c-l>, and your mapping will not be overridden. So just do this in your .vimrc:

 nmap <unique> <c-r> <Plug>NetrwRefresh

但是，更好的方法是不要踩Vim的脚趾.

However, a better way would be to not step on Vim's toes.
