在 Vim 中删除但不剪切一行

Question

这不是vi中删除行的重复，它在问不同的问题。我想删除一行而不剪切它（将它放在剪贴板中）。

我想复制行的一部分，删除一行，然后将该行的该部分粘贴到其他地方。使用v3w,dd然后p粘贴整行。

Answer 1

您正在寻找黑洞寄存器( :help quote_)。如果您添加"_到删除命令之前，内容将消失。因此，要删除并保留接下来的三个单词，然后删除整行，您可以使用d3w"_dd.

高级映射

在删除完整行的同时保留部分行的用例是常见的；我为此编写了一组映射：

"["x]dDD            Delete the characters under the cursor until the end
"                   of the line and [count]-1 more lines [into register x],
"                   and delete the remainder of the line (i.e. the
"                   characters before the cursor) and possibly following
"                   empty line(s) without affecting a register.
"["x]dD{motion}     Delete text that {motion} moves over [into register x]
"                   and delete the remainder of the line(s) and possibly
"                   following empty line(s) without affecting a register.
"{Visual}["x],dD    Delete the highlighted text [into register x] and delete
"                   the remainder of the selected line(s) and possibly
"                   following empty line(s) without affecting a register.

    let l:cnt = 1
    while l:currentLnum + l:cnt < line('$') && getline(l:currentLnum + l:cnt) =~# '^\s*$'
        let l:cnt += 1
    endwhile

    return '"_' . l:cnt . 'dd'
