如何告诉Vim只关闭文件中特定级别的折叠？

Question

例如，我怎么能告诉Vim只关闭文件中的所有2级折叠，让其他级别打开？

编辑：假设我的文件中有3个级别的折叠。 1,2和3.我只想关闭2级，将1级和3级打开。

Answer 1

您还可以通过'foldlevel'上的[count]设置zM：2zM;这比@ timrau的答案要短。

Answer 2

使用foldlevel。

:set foldlevel=2

Answer 3

function! FoldToTheLevel(TheLevel)    
    "set mark "f" at current position                   
    execute "normal! mf"
    "close all the folder recursively
    execute "normal! ggVGzC" 

    "open all the folder which have smaller level 
    let h=0  
    while h<a:TheLevel              
        execute "normal! ggVGzo"  
        let h+=1                                                                     
    endwhile 

    "open all the folder which have larger level           
    folddoclosed execute "normal! VzOzc" 
    "jump back and show in the middle
    execute "normal! `fzz"
endfunction   

command! -nargs=1 F call FoldToTheLevel(<f-args>)    

将此添加到.vimrc

运行

  

：F num

关闭级别为{num}
