Question

I am creating a method called SetLaunchingComponent which is used to set the makeprg with the variable passed in.This is how the script look like now.

function! SetLaunchingComponent(path) 
    set makeprg=$path
endfunction

Obviously the function isn’t working as i wished. As vim resolve the path environment as the system variable but not a:path. So what should i do?

Answer 1

To set a option you should use the following syntax:

let &makeprg=a:path
