Vim：如何防止跳出当前缓冲区？ [英] Vim: how to prevent jumps out of current buffer?

问题描述

我经常在Vim会话中打开几个缓冲区。这意味着我的跳转列表存储了多个缓冲区中的位置。但是，当我经常使用 Ctrl - O 跳转到先前的位置时，我不想离开缓冲区并想跳转到本地的先前位置。当前缓冲区。我该怎么做？

I frequently have several buffers open in my Vim session. This means that my jump list stores locations from several buffers. However, frequently when I use Ctrl-O to jump to a previous location, I do not want to leave the buffer and want to jump to previous locations "local" to the current buffer. How do I do this?

例如，假设我的跳转列表如下：

For example, assume my jump list looks as follows:

4   10   1 ~/aaa.m
3   20   1 ~/aaa.m
2   12   2 ~/xxx.m
1   15   1 ~/aaa.m

我想跳到文件的第15行 aaa.m 第一次按 Ctrl - O 。重要的是，下次我按下 Ctrl - O 时，我不想跳转到文件 xxx.m 。相反，我想跳到文件 aaa.m 的第20行;也就是说，我之前在当前缓冲区中的位置。 Vim的默认行为是将我带到文件 xxx.m 的第12行。有关如何实现此目标的任何想法？

I want to jump to line 15 of file aaa.m the first time I press Ctrl-O. Importantly, the next time I press Ctrl-O, I do not want to jump to file xxx.m. Rather, I want to jump to line 20 of file aaa.m; that is, my previous location within the "current" buffer. The default behaviour of Vim is to take me to to line 12 of file xxx.m. Any ideas on how I can achieve this?

推荐答案

请尝试以下跳转列表遍历功能。它将
从一个跳转列表位置连续移至另一个（使用 Ctrl + O
或 Ctrl + I 取决于提供给后退和 forw 参数的
的值） ，如果当前
位置与其开始所在的缓冲区在同一缓冲区中，则停止。
如果找不到与
当前缓冲区相关的跳转列表位置，则该函数将返回到开始之前
跳转列表的位置。

Try the following jump-list traversing function. It steps successively from one jump-list location to another (using Ctrl+O or Ctrl+I depending on the values that are supplied to its back and forw arguments), and stops if the current location is in the same buffer as that buffer it has started from. If it is not possible to find a jump-list location relating to the current buffer, the function returns to the position that jump-list had before start.

function! JumpInFile(back, forw)
    let [n, i] = [bufnr('%'), 1]
    let p = [n] + getpos('.')[1:]
    sil! exe 'norm!1' . a:forw
    while 1
        let p1 = [bufnr('%')] + getpos('.')[1:]
        if n == p1[0] | break | endif
        if p == p1
            sil! exe 'norm!' . (i-1) . a:back
            break
        endif
        let [p, i] = [p1, i+1]
        sil! exe 'norm!1' . a:forw
    endwhile
endfunction

将此功能用作
Ctrl + O / Ctrl + I -替换
锁定到当前缓冲区，创建

To use this function as a Ctrl+O/Ctrl+I-replacement locked to the current buffer, create mappings as it is shown below.

nnoremap <silent> <c-k> :call JumpInFile("\<c-i>", "\<c-o>")<cr>
nnoremap <silent> <c-j> :call JumpInFile("\<c-o>", "\<c-i>")<cr>
