什么是<leader>在 .vimrc 文件中? [英] What is the <leader> in a .vimrc file?

问题描述

我在许多 .vimrc 文件中看到 ，我想知道它是什么意思?

它有什么用?

对目的和用法做一个总体概述就好了.

解决方案

键默认映射到 .所以如果你有t的map，你可以默认用+t来执行.有关更多详细信息或使用 mapleader 变量重新分配它，请参阅

:帮助领导

<前>要定义使用mapleader"变量的映射，特殊字符串<领导>"可以使用.它被替换为mapleader"的字符串值.如果mapleader"未设置或为空，则使用反斜杠代替.例子::map <Leader>A oanother line <Esc>像这样工作::map A oanother line 但是之后::let mapleader = ","它的工作原理如下::map ,A oanother line <Esc>请注意，在映射时使用mapleader"的值定义.之后更改mapleader"对已定义的无效映射.

I see <leader> in many .vimrc files, and I am wondering what does it mean?

What is it used for?

Just a general overview of the purpose and usage would be great.

解决方案

The <Leader> key is mapped to by default. So if you have a map of <Leader>t, you can execute it by default with +t. For more detail or re-assigning it using the mapleader variable, see

:help leader

To define a mapping which uses the "mapleader" variable, the special string
"<Leader>" can be used.  It is replaced with the string value of "mapleader".
If "mapleader" is not set or empty, a backslash is used instead.  
Example:
    :map <Leader>A  oanother line <Esc>
Works like:
    :map A  oanother line <Esc>
But after:
    :let mapleader = ","
It works like:
    :map ,A  oanother line <Esc>

Note that the value of "mapleader" is used at the moment the mapping is
defined.  Changing "mapleader" after that has no effect for already defined
mappings.
