I have a vimrc file. In that file i have the following two lines.

noremap gg :silent exec "!/home/john/gf.sh /home/john/guides/"<enter><C-L>

nmap gh tlet @"=system('perl /home/john/get_buffer.pl')<enter>P<enter>^

The first command runs script gf.sh. Which, long story short, prints a file selected by the user, into /tmp/file.

The second command, gh. Prints /tmp/file, into buffer @". And then prints that buffer, wherever I happen to be in Vim.

What I am trying to achieve, is to execute both of those things with a single command. I just don't understand how to achieve that. I have been trying for well over an hour.

How can I, achieve those two functionalities, at once?

  • Is the nmap on gh relevant? The tlet sequence looks a bit odd, so I can't tell if it's another mapping or just some keystrokes you want to have. As for combining, might be easier to use a function.

  • well, now i type gg, run that script where i tell which file should be catted into /tmp/file. Then I have to make the rest happen, somehow. So by typing "gh" in normal mode, I run the buffer perl script and paste its output automatically.

  • Are you looking for :help :bar? It sounds like you wish to run two commands, one immediately after the other

  • Yes i want to run two commands, one after the other. But as you can see, the latter one needs to return its output into the buffer.

  • Ideally your .sh script would print out content to STDIN then you just do :put=systemlist('script.sh'). Other you just need to run your commands one after another, e.g. script.sh; cat /tmp/foo Mar 5, 2021 at 14:06

From the comments the OP wishes to execute multiple commands in succession. In particular, the commands silent exec ... followed by let @"= .... As D Ben Knoble suggests, this is a typical use case of a function.

function Foo()
  silent exec "!/home/john/gf.sh /home/john/guides/"
  redraw!
  let @"=system('perl /home/john/get_buffer.pl')
  normal! Pj^
endfunction

Then, one can call this function with a mapping

nnoremap gg :call Foo()<CR>

  • Thank you very much. I need to read up on some vimscript.

  • Glad to be of help! I should have mentioned that :normal xxx acts as though xxx was pressed in normal mode by the user. :help :normal will provide more details.

  • no wait, the function gets implemented, every time i run vim. i put that function in my vimrc file.

  • Yes, place both the function and mapping in your vimrc.... or am I missing something?

  • I changed the function name, into something that starts in a lowercase. Which caused an error. But its corrected now.
