是否可以在 Vim 中跳转到下一个关闭的折叠? [英] Is it possible to jump to the next closed fold in Vim?

问题描述

在 Vim 中，我经常发现自己想做一个快速的 zk 或 zj 来跳转到文件中的上一个或下一个折叠.问题是，我经常想跳过所有打开的折叠，而只是跳到最近的关闭折叠.

In Vim, I often find myself wanting to do a quick zk or zj to jump to the previous or next fold in a file. The problem is, I frequently want to skip all the open folds, and just jump to the nearest closed fold.

有没有办法做到这一点?我在帮助中没有看到内置的键盘映射.

Is there a way to do this? I see no built-in keymap in the help.

推荐答案

让我提出描述行为的以下实现.

Let me propose the following implementation of the described behavior.

nnoremap <silent> <leader>zj :call NextClosedFold('j')<cr>
nnoremap <silent> <leader>zk :call NextClosedFold('k')<cr>

function! NextClosedFold(dir)
    let cmd = 'norm!z' . a:dir
    let view = winsaveview()
    let [l0, l, open] = [0, view.lnum, 1]
    while l != l0 && open
        exe cmd
        let [l0, l] = [l, line('.')]
        let open = foldclosed(l) < 0
    endwhile
    if open
        call winrestview(view)
    endif
endfunction

如果映射需要接受数量的计数相应动作的重复次数，可以实现用于重复任何给定命令的简单函数:

If it is desirable for the mappings to accept a count for the number of repetitions of the corresponding movement, one can implement a simple function for repeating any given command:

function! RepeatCmd(cmd) range abort
    let n = v:count < 1 ? 1 : v:count
    while n > 0
        exe a:cmd
        let n -= 1
    endwhile
endfunction

然后重新定义上面的映射如下:

and then redefine the above mappings as follows:

nnoremap <silent> <leader>zj :<c-u>call RepeatCmd('call NextClosedFold("j")')<cr>
nnoremap <silent> <leader>zk :<c-u>call RepeatCmd('call NextClosedFold("k")')<cr>
