I know that using VIM I can format C++ code just using
gg=G
Now I have to format 30 files, so doing it by hand becomes tedious. I had a look how to do it passing external commands to VIM, so I tried
vim -c gg=G -c wq file.cpp
but it does not work.
Can you give me a hint?
Thanks
Why not load all the files up in buffers and use bufdo to execute the command on all of them at one time?
:bufdo "execute normal gg=G"
Change -c gg=G to -c 'normal! gg=G'. -c switch accepts only ex mode commands, gg=G are two normal mode commands.
I prefer a slight change on the :bufdo answer. I prefer the arg list instead of the buffer list, so I don't need to worry about closing current buffers or opening up new vim session. For example:
:args ~/src/myproject/**/*.cpp | argdo execute "normal gg=G" | update
args sets the arglist, using wildcards (** will match the current directory as well as subdirectories)
| lets us run multiple commands on one line
argdo runs the following commands on each arg (it will swallow up the second |)
execute prevents normal from swallowing up the next pipe.
normal runs the following normal mode commands (what you were working with in the first place)
update is like :w, but only saves when the buffer is modified.
This :args ... | argdo ... | update pattern is very useful for any sort of project wide file manipulation (e.g. search and replace via '%s/foo/bar/ge' or setting uniform fileformat or fileencoding).

I'm recently working on a project in vim, and I need to execute the same command to different files which are in the same folder in command-line mode multiple times.
like
:%s/V1/V2/g
Is there a easiler way to do this?
It's command-line mode, not "command mode".
From within Vim
Set your :help argument-list to the desired list of files:
:arg /path/to/dir/*.xyz
Perform your substitution on every file in the argument list and write it if there was a change:
:argdo %s/V1/V2/g | update
See :help :arg, :help :argdo, :help :update.
From your shell
Start Vim with each desired file as argument:
$ vim /path/to/dir/*.xyz
Perform your substitution on every file in the argument list and write it if there was a change:
:argdo %s/V1/V2/g | update
I have a bash script that assembles some data, then pipes it through fzf for the user to choose, then manipulates the choice, then prints it to stdout.
This simulates the script:
#!/bin/sh
echo hello | fzf | sed 's/h/j/g'
This works great from the command line, but when running it from vim to include in the current buffer, the fzf TUI never displays, and I get ANSI escape sequences included in the result:
It doesn't matter how I run the command from vim. I've tried :read !{cmd}, :.!{cmd}, and even :let a=system('{cmd}').
For example, I would expect this to work:
:read !echo hello | fzf | sed 's/h/j/g'
fzf seems to be confusing stdout for a tty.
I know this isn't a limitation of vim, since if I substitute fzf for another interactive chooser with a tty, it works.
Is there an fzf or vim option to make this work?
Vim doesn't deal with interactive commands that easily. As you've seen, fzf outputs a lot of code to manipulate the display, and read is expecting a raw result.
You can do this with execute instead of using read directly.
Building off another answer ( Capture the output of an interactive script in vim ) but changing things up to work with fzf, I've modified #joshtch's solution to work with an arbitrary script, and checked that it works with fzf:
my-fzf-script.sh:
#!/bin/sh
ls | fzf
and the vim side of things:
function! <SID>InteractiveFZFCommand()
let tempfile=tempname()
execute '!./my-fzf-script.sh >' . shellescape(tempfile)
try
silent execute 'read' tempfile
finally
call delete(tempfile)
endtry
endfunction
command! -nargs=0 InteractiveFZFCommand call <SID>InteractiveFZFCommand()
How can I paste the contents of the system clipboard to all files in the argument list in Vim?
You can do the following:
:argdo execute 'normal! "+p' | w
Explanation:
:argdo Run the command that follows on each file in the argument list. Alternatively, you can use :windo to run a command on each window, or :bufdo to run a command on each buffer.
execute "normal! ..." Run the sequence of commands after normal! as if they were entered in normal mode. Ignore all mappings and replace string escape sequences like \<esc>.
"+p Paste the register for the system clipboard. Note that Vim has to be compiled with the +clipboard feature enabled for this to work.
| w Write every file, whether it was updated or not. Alternatively, use | update to only write files that were changed.

Vim 101: Search and Replace on Multiple Files
Run a command in multiple buffers
Originally answered by Roberto Balejík
I want to do the following for multiple files using Vim:
Copy all text in each file
Replace some text
Paste the copied text at the end of the each file
Replace some other text
Here are my commands for one file:
:%y
:%s/old1/new1/g
:G
:P
:%s/old2/new2/g
Can anybody tell me the syntax to do so? Especially that I'm new to Vim!
I found out that argdo can execute commands on multiple files. I found many examples to use argdo in replacing text, but I couldn't find the syntax to use argdo with :%y, :G, or :P
Thanks.
Like #ib mentioned, I'd do this with ex commands1
:argdo %y | %s/old1/new1/g | $pu | %s/old2/new2/g
There's also a good chance that you might want to operate on exclusive ranges (do the first substitution only on the first part, and the second only on the second):
:argdo $mark a | %co$ | 1,'a s/old1/new1/g | 'a,$s/old2/new2/g
To allow non-matching substitutions, add s///e and add silent! to make operation much faster in the case of many files.
:silent! argdo $mark a | %co$ | 1,'a s/old1/new1/ge | 'a,$s/old2/new2/ge
1 (note that argdo expects an Ex command list by default. You'd use e.g. argdo norm! ggyG to use normal mode commands)
UPD: my Vim-fu is not as strong as #ib's or #sehe's ones, so you might want to use the solutions they suggested instead of mine one.
But, my solution is easier to edit and to debug personally for me (as a Vim apprentice), so, let it be here anyway.
You can add the following temporary function in your vimrc:
function! MyTmpFunc()
:%y
:%s/old1/new1/g
normal! G
normal! P
:%s/old2/new2/g
endfunction
Then restart Vim with the files you need to affect (something like vim myfile1.txt myfile2.txt myfile3.txt), and execute the following command:
:argdo call MyTmpFunc()
That's what you described in your question: function MyTmpFunc() will be called for each argument given to Vim.
Now you can delete MyTmpFunc() from vimrc.
Be also aware with :bufdo - it calls some command for each opened buffer. There is also :windo, which executes command for each window, but personally I found :bufdo the most useful.
Also please note that you don't have to create temporary function if you need to execute just a single command in the each buffer. Say, if you need just to replace "old1" to "new1" in the each buffer, then you can execute the following command:
:bufdo %s/old1/new1/g
and that's it.
In a given working directory, if I do
:tabe **/test*.py
vim complains with E77: Too many file names. What if I want it to open every matching file in a separate tab? There must be a way to do it, but I can't find it.
You could use the args list and argdo like so:
:args **/test*.py
:argdo tabe %
However, the syntax event is turned off by argdo (to speed up the normal use case), so the files will be loaded without syntax at first. You could follow it up with a :syntax on to force the syntax event on all loaded buffers. Compressed into one line (need to wrap argdo in execute so it doesn't absorb the following |):
:args **/test*.py | execute 'argdo tabe %' | syntax on
Alternately, you can open vim from the command line via:
vim -p **/test*.py
But that will max out at 10 tabs.
You can use the following:
:next **/test*.py
It opens all the files.
To map it
nmap <c-d> :args **/*.tpl<bar>execute 'argdo tabe %'<bar>syntax on<cr>
But still it displays list of files, you have to press enter few times (depending of number of files).
This functionality can be included as a command in your .vimrc file:
"open all files in seperate tabs
command -nargs=1 OpenAll call <SID>openAll(<f-args>)
function! s:openAll(dir)
execute 'args ' . a:dir
silent argdo tabe %
syntax on
endfunction
With this function running :OpenAll **/*.py from vim will quickly open all files into new tabs
None of the other answers works for me, but this is fine:
find <path> -iname <pattrn> | xargs -o vim -p
all files are visible in different tabs
file lookup is recursive
Note, vim can limit tabs - to be changed by set tabpagemax=42.
Also, if you wonder how to close all tabs at once, use :qa
