Can I transfer a file to Vim?

Question

I know that I can use AWK, but I am in a Windows window. I am making a function for others who may not have AWK. I also know that I can write a program in C, but I would not want to create and compile something for the small Vim utility that I create.

The source file may be

Answer 1

Here is the Vim command. This way you do not need 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() 

Place this in the newly created .vim file in the vim / plugin directory or place it on your [._] vimrc.
Run :TransposeBuffer to wrap the current buffer

Answer 2

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

Just change vim.current.buffer accordingly and you will install.

To be more specific:

 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 

Answer 3

If the scripts do not do this for you, you can write actions to the register (carriage return is added for reading):

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

This will give you a macro that you could run against the above example, or any lines of 2 lines of the same length. You need to know the length of the string so that you can repeat the operation with the correct amount of time.

 16@a 

Pretty basic solution, but it works.

Answer 4

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

 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 single line version,

 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' 

Answer 5

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

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

Answer 6

I developed a vim plugin for this. You can find it here . Run :Transpose to transpose the entire file.
