在vim中切换功能 [英] Toggle function in vim

问题描述

基本上我想做的是

map ,e :call ToggleEssayMode()<CR>
function! ToggleEssayMode()
if toggle==true
  :map j gj
  :map k gk
  toggle=false
else
  :umap j
  :umap k
  toggle=true
enndfunction

我已经看了一阵子了，但是我能找到的所有使用的人都是保留的vim变量.我可以自己设定变量吗?有更正确的方法吗?

I've looked around for a while, but all i could find people using were the reserved vim variables. Can I make my own variable? Is there a more correct way of doing this?

推荐答案

除非您使用单独的函数来启用和禁用，否则将需要一个flag变量，为了将其与其余配置隔离，我建议编写一个小插件.例如，在〜/.vim/plugin/中创建文件 essay.vim (实际名称无关紧要，只要它以 .vim 结尾即可).具有以下内容:

Unless you use separate functions for enabling and disabling, you will need a flag variable, and in order to isolate this from the rest of your configuration, I would recommend writing a small plugin. For example, create a file essay.vim (the actual name is irrelevant, as long as it ends in .vim) in ~/.vim/plugin/ with the following content:

let s:enabled = 0

function! ToggleEssayMode()
    if s:enabled
        unmap j
        unmap k
        let s:enabled = 0
    else
        nnoremap j gj
        nnoremap k gk
        let s:enabled = 1
    endif
endfunction

然后，调用 ToggleEssayMode()的映射可以在同一文件中，也可以在您的 .vimrc 中.

The mapping to call ToggleEssayMode() can then be in the same file or in your .vimrc.

关于您的代码的一些评论:

Some remarks about your code:

• 使用 let 来分配变量(有关选项，请参见 set ).
• Vim不支持 true 和 false ；改用 1 和 0 .
• 每个 if 需要结束符 endif .
• umap 应该为 unmap ；前者不存在.
为了避免递归映射，应使用
• nnoremap .
在脚本中的命令之前不需要
• :.

• Use let in order to assign variables (cf. set for options).
• Vim does not support true and false; use 1 and 0 instead.
• Every if needs a closing endif.
• umap should be unmap; the former does not exist.
• nnoremap should be used in order to avoid recursive mappings.
• : is unnecessary before commands in scripts.
