Definition ​

Add ! after function to overwrite if it is already defined (useful when reloading the script).

vim
function! Simple(myarg)
  echo a:myarg
  return 0
endfunction

function! OptionalArgs(...)
  echo a:0    " Number of arguments
  echo a:1    " Optional argument
  echo a:000  " List with all arguments
endfunction

Usage ​

Use the call keyword to call the function.

vim
call Simple(1)
