Unable to run many Commands in Vim's visual mode externally

Question

I have the following commands in a README file:

./Setup ...
./Setup ...
./Setup ...

I want to run them by selecting the codes visually and then running them.

I run unsuccessfully

: '<,'> !

Current code after Luc's comments in his answer

My code in .vimrc which I have not managed to get to work:

vmap <silent> <leader>v y:exe '!'.join(split(@", "\n"),';')<cr>

I am trying to make make a keyboard combination for

v yy

How can you get the above command work, such that you can run file's commands directly in Vim?

Answer 1

• First select your text,
• then copy it with y,

• and finally, you can execute:

  :exe '!'.join(split(@", "\n"),';')

Answer 2

This might be oversimplifying things, but why not just do:

:e README
:%!bash

This filters the current file through bash, executing each line as a command. The current buffer is replaced by the output of running all of the commands in the file.

It might be helpful to do a :w RESULTS to save it as another file first, so you don't accidentally overwrite the original:

:e README
:w RESULTS
:%!bash

You had said you wanted to do this with a visual selection, which would work just as well After you select what you want to execute, type :. '<,'> will automatically be prepended to the current command. '< is the mark of the beginning of the current selection, whereas '> is the mark at the end of the current selection. You can just run just those commands you have selected just like above:

:'<,'>!bash

This will replace just the selected commands with the output of executing those commands.
