如何修复 Vim 中的 Leader Key Beep？

Question

我无法让领导密钥在 vim 中工作。我已经解决了很长一段时间了。

我已经做过的事情：

• 将领导键映射到另一个键
• 在没有插件/_vimrc 文件的情况下启动 vim

_vimrc

let mapleader = ';'
source $VIMRUNTIME/vimrc_example.vim
source $VIMRUNTIME/mswin.vim

set diffexpr=MyDiff()
function MyDiff()
  let opt = '-a --binary '
  if &diffopt =~ 'icase' | let opt = opt . '-i ' | endif
  if &diffopt =~ 'iwhite' | let opt = opt . '-b ' | endif
  let arg1 = v:fname_in
  if arg1 =~ ' ' | let arg1 = '"' . arg1 . '"' | endif
  let arg1 = substitute(arg1, '!', '\!', 'g')
  let arg2 = v:fname_new
  if arg2 =~ ' ' | let arg2 = '"' . arg2 . '"' | endif
  let arg2 = substitute(arg2, '!', '\!', 'g')
  let arg3 = v:fname_out
  if arg3 =~ ' ' | let arg3 = '"' . arg3 . '"' | endif
  let arg3 = substitute(arg3, '!', '\!', 'g')
  if $VIMRUNTIME =~ ' '
    if &sh =~ '\<cmd'
      if empty(&shellxquote)
        let l:shxq_sav = ''
        set shellxquote&
      endif
      let cmd = '"' . $VIMRUNTIME . '\diff"'
    else
      let cmd = substitute($VIMRUNTIME, ' ', '" ', '') . '\diff"'
    endif
  else
    let cmd = $VIMRUNTIME . '\diff'
  endif
  let cmd = substitute(cmd, '!', '\!', 'g')
  silent execute '!' . cmd . ' ' . opt . arg1 . ' ' . arg2 . ' > ' . arg3
  if exists('l:shxq_sav')
    let &shellxquote=l:shxq_sav
  endif
endfunction

预期行为

在 vim 屏幕的右下角应该有一个 \（想将 \ll 用于 vimtex），但它只是发出哔哔声。我可以在 CMD-Window 或 vim 插入模式下使用 \，但不能在“普通”-vim-window (ESC, ESC) 中使用它

Answer 1

尝试将领导键映射到您之前尝试过的另一个键，但将let mapleader = ';' 放在_vimrc 的第一行（而不是最后一行），因为<Leader> 和<LocalLeader> 已展开定义 map/noremap 时。通过在最后设置领导者会导致之前完成的所有映射（在插件中以及在 mswin.vim 和 vimrc_example.vim 中）无法与新领导者一起使用。

所以_vimrc 将是：

let mapleader = ';'
source $VIMRUNTIME/vimrc_example.vim
source $VIMRUNTIME/mswin.vim

set diffexpr=MyDiff()
function MyDiff()
  let opt = '-a --binary '
...
