An interactive call is fundamentally a combination of "run the interactive spec to get the args, and then call the function with those args". So, in a sense you can't avoid it. But you can discourage non-interactive calls in various ways, depending on how important you think it is. The most standard way is to use (declare (interactive-only )) so that the compiler will emit a warning when it sees a non-interactive call to that function ( is the replacement you recommend for non-interactive calls). A more "forceful" way is to wrap your interactive function inside a trivial keyboard macro: (defalias 'my-command (vector (lambda (...) (interactive ..) ...))) this way `my-command` is a valid command but it's not a valid function. I'd not recommend such a measure, tho. Stefan
