26.3; `called-interactively-p' doc is incorrect and misleading |
|

1. Wrong signature:
called-interactively-p is a compiled Lisp function in 'subr.el'.
(called-interactively-p KIND)
It should be (called-interactively-p &optional KIND).
2. Nothing is said about the case where KIND is absent or nil.
Nothing is said about the behavior where KIND is anything other than
`interactive' or `any'. It seems that it returns nil for anything
other than those two symbols, regardless of whether the calling
function was called interactively.
How misleading is that? No error - nil (as "false") presumably
means called non-interatively, but in fact it means nothing in this
case. Result: bugged code, with no help from Emacs about the bug.
3. The same problems exist for the Elisp manual, node `Distinguish
Interactive'.
4. On the other hand, if the intention really is to _require_ KIND, so
that what the Elisp manual says is true: "KIND should be either the
symbol 'interactive' or the symbol 'any'", then the function should
raise an error when KIND is missing (and the "should" should then
be changed to "must").
5. This bug seems to still be present in Emacs 28 (recent snapshot).
There, there's the additional bug that this appears right after the
first doc-string line, for `C-h f':
Probably introduced at or before Emacs version 22.1.
Such meta-information should not be placed up front like that. It's
not in any sense the most important info. If it's shown at all, it
should be placed at the end, after a horizontal separator. It's
essentially a footnote.
Yes, This (#5) is a separate, unrelated bug. I don't feel like
filing it separately. But it should be fixed.
