How to execute file I'm editing in Vi(m)

Question

How to execute file that I\'m editing in Vi(m) and get output in split window (like in SciTE)?

Of course I could execute it like that:

:!scriptname
<         


        

Answer 1

Just use colon and exclamatory mark as shown below

:!< script_name>

Answer 2

There is the make command. It runs the command set in the makeprg option. Use % as a placeholder for the current file name. For example, if you were editing a python script:

:set makeprg=python\ %

Yes, you need to escape the space. After this you can simply run:

:make

If you wish, you can set the autowrite option and it will save automatically before running the makeprg:

:set autowrite

This solves the execute part. Don't know any way of getting that output into a split window that doesn't involve redirection to file.

I'd recommend the plugin quickrun. It's fast and simple to configure. Here's a little demonstration:

Answer 4

For Shell script I've used

:set makeprg=%

:make

Answer 5

You can use vim's plugin bexec. To my knowledge the latest version is 0.5.

Then:

$ mkdir -p ~/.vim/plugin
$ mv bexec-0.5.vba ~/.vim/plugin
$ vim ~/.vim/plugin/bexec-0.5.vba

Inside vim itself while editing the .vba file do:

:so %

Some output will show up letting you know that bexec.vim has been written as well as documentation, etc..

Now, you can test it by opening your (whatever language script that has an #! interpreter working properly) in vim and run

:Bexec 

Note: I wanted the split to be vertical rather than horizontal, so I did:

$ grep -i -n split ~/.vim/plugin/bexec.vim | grep -i hor
102:    let bexec_splitdir = "hor" " hor|ver
261:        exec {"ver":"vsp", "hor":"sp"}[g:bexec_splitdir]

and changed the value of from "hor" to "ver"..

I know it's an old question, but I hope this can help someone out there. I have been running in the same issue while taking Coursera's Startup Engineering course where professor Palaji uses Emacs and I don't like Emacs..

I was looking for this script (python/Windows) for quite some time. As there is no "tee" in Windows I changed it to:

function! Setup_ExecNDisplay()
  execute "w"
  let n=expand('%:t')
  execute "silent ! python % > d:\\temp\\output_".n ." 2>&1"
  execute "vsplit d:\\temp\\output_".n
  execute "redraw!"
  set autoread
endfunction

function! ExecNDisplay()
  execute "w"
  let n=expand('%:t')
  execute "silent ! python % > d:\\temp\\output_".n . " 2>&1"
endfunction

:nmap <F9> :call Setup_ExecNDisplay()<CR>
:nmap <F2> :call ExecNDisplay()<CR>
