       set cmd to "/usr/local/bin/nvim "
       set filepaths to ""
       if input is not {} then
         repeat with currentFile in input
           set filepaths to filepaths & quoted form of POSIX path of currentFile & " "
         end repeat
       end if

         activate
         if terminalIsRunning is true then
