void variable error in function diary-anniversary

void variable error in function diary-anniversary

[stardiviner]

I have:

```org

* test anniversary

%%(diary-anniversary 12 8 2007)

```

When I execute [M-: (diary-anniversary 12 8 2007) RET], I got error:

Symbol's value as variable is vodi: date

Which Emacs version?
Could you set "Options => Enter Debugger on Error", then reproduce
the problem, then send us the backtrace that you (hopefully) get?

I'm using latest Emacs version from `master` branch.

Current version: GNU Emacs 27.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ 
Version 3.22.26) of 2017-12-16


And here is the edebug backtrace (check out the FIXME):

#+begin_src emacs-lisp

(defun diary-anniversary (month day &optional year mark)
   "Anniversary diary entry.
Entry applies if date is the anniversary of MONTH, DAY, YEAR.
The order of the input parameters changes according to
`calendar-date-style' (e.g. to DAY MONTH YEAR in the European style).

The diary entry can contain `%d' or `%d%s'; the %d will be replaced
by the number of years since the MONTH, DAY, YEAR, and the %s will
be replaced by the ordinal ending of that number (that is, `st',
`nd', `rd' or `th', as appropriate).  The anniversary of February 29
is considered to be March 1 in non-leap years.

An optional parameter MARK specifies a face or single-character
string to use when highlighting the day in the calendar."
   (with-no-warnings (defvar date) (defvar entry))
   (let* ((ddate (diary-make-date month day year))
          (dd (calendar-extract-day ddate))
          (mm (calendar-extract-month ddate))

          (y (calendar-extract-year date)) ; FIXME: here date is void.
          (diff (if yy (- y yy) 100)))
     (and (= mm 2) (= dd 29) (not (calendar-leap-year-p y))
          (setq mm 3
                dd 1))
     (and (> diff 0) (calendar-date-equal (list mm dd y) date)
          (cons mark (format entry diff (diary-ordinal-suffix diff))))))

The calendar and diary modules assume that the symbol 'date' is
(dynamically) bound to today's date.  So if you want to evaluate a
function like diary-anniversary by hand (so to speak), you have to do
something like this (N.B. the (month day year) format for the date):

(setq date '(12 21 2017))
(12 21 2017)
(setq entry "foo %d")
"Test anniversary %d"
(org-anniversary 2015 12 21)
(nil . "Test anniversary 2")

This is not a backtrace :-(

But to get back to the original problem:

Do you only get this error in your M-: use case (which is normal), or do
you also see it when you use that in your diary file?

If it's a new problem that was not present in earlier versions of Emacs,
then please, please, pretty please, `M-x report-emacs-bug`.

Re: void variable error in function diary-anniversary

[numbchild]

Sorry for this. I only have this error in when in [M-:]. I also asked
Org-mode mailing list. I can include diary anniversary now. So it is not
Emacs bug.
