Save and run at the same time in Vim

Question

I do a lot of Python quick simulation stuff and I\'m constantly saving (:w) and then running (:!!). Is there a way to combine these actions?

Maybe a "save and run&qu

Answer 1

This is what I put in my .vimrc file and works like a charm:

nnoremap r :w:!!

Of course you need to run your shell command once before this, so it knows what command to execute.

Example:

:!node ./test.js
