called-interactively-p

called-interactively-p

[Stefan Monnier]

Following the discussion we had here around interactive-p and
called-interactively-p, I've just installed the following changes:
- called-interactively-p takes a parameter `kind' which can be
  either `interactive' or `any', the first corresponds to what
  interactive-p used to do and the second to what called-interactively-p
  used to do.
  The function still works if called without any argument, but the
  byte-compiler will complain about the missing argument (it's the best
  trade-off I could come up between breaking compatibility and
  enouraging people to pass as argument).
- interactive-p is marked obsolete.  This is not quite as simple as it
  sounds, because interactive-p has its own byte-code.  So we'll have to
  improve our "obsolescence" infrastructure if we want to handle this
  right.  For now, all the "make-obsolete" does in the end is to make
  C-h f tell you the function is obsolete, which seems good enough for
  now, especially given the 300 or so calls to interactive-p we still
  have in our own code.

I will take care of the ones in Org.

Well, it turns out that I don't know a good way to take care of this.
I would like to have Org be compatible with Emacs 22 and also XEmacs,
and I don't know how I can do this with the new `called-interactively',
except for creating diverging code bases.

Advice would be appreciated.

Thanks.

Yes, this is a problem.  The best I can offer is to use a macro that
expands to either of the alternatives (a function wouldn't work because
it would cause interactive-p to always return nil).

(defmacro org-called-interactively-p (kind)
  (condition-case nil
      (progn (called-interactively-p nil)
             ;; If the call didn't signal an error, then the new form
             ;; is supported: use it.
             `(called-interactively-p ,kind))
    (wrong-number-of-arguments
     ;; Probably Emacs-23.1.
     (if (equal (eval kind) 'interactive)
         `(interactive-p)
       `(called-interactively-p)))
    (error
     ;; called-interactively-p seems not to be supported, fallback
     ;; on the good ol' interactive-p.
     `(interactive-p))))

Of course the above code is guaranteed 100% untested.

Remember thread "interactive-p and called-interactively-p".
Think Drew Adams was right and your first response too.

Otherwise we see things going still more complicated.

And a macro will only work if the user runs compiled code, right?

I don't think so: it should work correctly in either case.
