如何在 Vim 中转置文件中行和列的内容? [英] How to transpose the contents of lines and columns in a file in Vim?

问题描述

我知道我可以使用 Awk，但我在 Windows 机器上，并且我正在为可能没有 Awk 的其他人制作一个函数.我也知道我可以编写一个 C 程序，但我不希望我正在制作的一个小 Vim 实用程序需要编译和维护.

I know I can use Awk, but I am on a Windows box, and I am making a function for others that may not have Awk. I also know I can write a C program, but I would love not to have something that requires compilation and maintenance for a little Vim utility I am making.

原始文件可能是:

THE DAY WAS LONG

转位后应该变成:

HH
EE

DW
AA
YY

WW
AA
SS

LF

推荐答案

这是一个 Vim 语言的命令.所以你不必编译带有 +python 支持的 Vim.

Here is a command in Vim language. So you don't have to compile Vim with +python support.

function! s:transpose()
    let maxcol = 0
    let lines = getline(1, line('$'))

    for line in lines
        let len = len(line)
        if len > maxcol 
            let maxcol = len
        endif
    endfor

    let newlines = []
    for col in range(0, maxcol - 1)
        let newline = ''
        for line in lines
            let line_with_extra_spaces = printf('%-'.maxcol.'s', line)
            let newline .= line_with_extra_spaces[col]
        endfor
        call add(newlines, newline)
    endfor

    1,$"_d
    call setline(1, newlines)
endfunction

command! TransposeBuffer call s:transpose()

把这个放在 vim/plugin 目录中新创建的 .vim 文件中，或者把它放到你的 [._]vimrc 中.
执行:TransposeBuffer转置当前缓冲区

Put this in newly created .vim file inside vim/plugin dir or put this to your [._]vimrc.
Execute :TransposeBuffer to transpose current buffer
