我可以在Vim中转置文件吗？

I know I can use AWK but I am on a Windows box. 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 have to create maintain and compile something for a little Vim utility I am making.

我知道我可以使用AWK,但我在Windows机器上。我正在为可能没有AWK的其他人提供功能。我也知道我可以写一个C程序,但我不想为我正在制作的一个小Vim实用程序创建维护和编译。

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

这是Vim语言中的命令。所以你不必用+ python支持编译Vim。

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()

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

将它放在vim / plugin dir中新创建的.vim文件中,或者将它放到[._] vimrc中。执行:TransposeBuffer转置当前缓冲区

#2

Vim support for a number of scripting languages built in -- see the Python interface as an example.

Vim支持内置的许多脚本语言 - 以Python接口为例。

Just modify vim.current.buffer appropriately and you're set.

只需适当修改vim.current.buffer即可。

To be a little more specific:

更具体一点:

function! Rotate()
python <<EOF
import vim, itertools
max_len = max((len(n) for n in vim.current.buffer))

vim.current.buffer[:] = [
    ''.join(n) for n in itertools.izip(
        *( n + ' ' * (max_len - len(n))
           for n in vim.current.buffer))]
EOF
endfunction

#3

If scripts don't do it for you, you could record the actions to a register (the carriage returns are added for readability):

如果脚本没有为您执行此操作,则可以将操作记录到寄存器(为了便于阅读,添加了回车符):

qa
1G0
xGo<Esc>p
1G0j
xGp
q

This will give you a macro that you could run against the example above, or any 2-line strings of the same length. You only need to know the length of the string so you can iterate the operation the correct number of time

这将为您提供一个可以针对上面的示例运行的宏,或者任何相同长度的2行字符串。您只需要知道字符串的长度,这样就可以在正确的时间内迭代操作

A fairly basic solution, but it works.

一个相当基本的解决方案,但它有效。

#4

The following function performs required editing operations to "transpose" the contents of the current buffer.

以下函数执行所需的编辑操作以“转置”当前缓冲区的内容。

fu!T()
let[m,n,@s]=[0,line('$'),"lDG:pu\r``j@s"]
g/^/let m=max([m,col('$')])
exe'%norm!'.m."A \e".m.'|D'
sil1norm!@s
exe'%norm!'.n.'gJ'
endf

Below is its one-line version,

以下是它的单行版本,

let[m,n,@s]=[0,line('$'),"lDG:pu\r``j@s"]|exe'g/^/let m=max([m,col("$")])'|exe'%norm!'.m."A \e".m.'|D'|exe'sil1norm!@s'|exe'%norm!'.n.'gJ'

#5

Charles Duffy's code could be shortened/improved using izip_longest instead of izip:

使用izip_longest而不是izip可以缩短/改进Charles Duffy的代码:

function! Rotate()
    :py import vim, itertools
    :py vim.current.buffer[:] = [''.join(c) for c in itertools.izip_longest(*vim.current.buffer, fillvalue=" ")]
endfunction

#6

I've developed a vim plugin to do it. You can find it here. Run :Transpose to transpose the whole file.

我开发了一个vim插件来做到这一点。你可以在这里找到它。运行:转置以转置整个文件。
