Whenever I need to run ruby from VIM I used to exit and run the script and load back VIM. ( Bad ) Then learned to use **:!ruby** which would execute the supplied command in shell and return back. ( Better ) But the below gist would help you run with press of F6 key.
" Save the current file and run current ruby script
function! RunRuby()
:w
let name = input('Enter Argument (if any): ')
execute ':!ruby % '.name
endfunc
" Use F6 to trigger a run
