,----[ C-h f interactive-p RET ]
| interactive-p is a built-in function in `C source code'.
| (interactive-p)
|
| Return t if the function was run directly by user input.
| This means that the function was called with `call-interactively'
| (which includes being called as the binding of a key)
| and input is currently coming from the keyboard (not in keyboard macro),
| and Emacs is not running in batch mode (`noninteractive' is nil).
|
| The only known proper use of `interactive-p' is in deciding whether to
| display a helpful message, or how to display it. If you're thinking
| of using it for any other purpose, it is quite likely that you're
| making a mistake. Think: what do you want to do when the command is
| called from a keyboard macro?
|
| If you want to test whether your function was called with
| `call-interactively', the way to do that is by adding an extra
| optional argument, and making the `interactive' spec specify non-nil
| unconditionally for that argument. (`p' is a good way to do this.)
