Re: display faster output of external app

system(s:cmd) produces something like "useful message\n" like `system('echo
"useful message"')' does, am I right? You need just system(s:cmd)[:-2] then.

You're right

 

Your code is a bit strange (I don't get why you need `output' to be global

and constructed `cmd' to be script-local), but nothing more can be said at this
point.

global to debug and have possibility after the run of vimscript to do

echo g:myglobal
