How do I run a script from within the vim editor?

Question

When within vim (the editor I use mostly because of the terminal integration), I want to run my script (e.g. Python or Javascript) from within vim.

I do not mind if it opens a new window, I would just like to know if there is an editor command for save/run. TNX1.0E6,

Answer 1

You can run commands inside of vim with !

:!echo "hello"

The symbol % is a shortcut for the name of the current open file, so you can execute your current file with

:!%

The console output will appear, and you press enter to return to editing your file

You can add a keybind to save and run in your ~/.vimrc

nnoremap <F5> <esc>:w<enter>:!%:p<enter>
inoremap <F5> <esc>:w<enter>:!%:p<enter>

I specifically use this to compile and view LaTeX documents in vim:

map     <F5>            :! pdflatex "%"<CR><CR>
map     <F6>            :! xdg-open "%<.pdf";<CR>

the "%<" gets the name of the current file in buffer without the extension, (i.e., when I'm editing book.tex, it returns book so I can attach my own ending.

You can set up a Makefile in your project folder and then use vim's built-in :make command. Since Makefiles are ridiculously powerful and aren't limited to compiling C applications, you can set it up to call your script and do any additional processing that is needed.

The contents of the Makefile would look like:

all:
        yourscript.py
