that was untested and has room for improvement (as mentioned in this
thread).
This is untested again, but hopefully better ;)
#+BEGIN_SRC emacs-lisp
(defun process-diary-file ()
"Perform some manipulation of the diary file"
(interactive)
(let (a)
(find-file (expand-file-name "~/diary"))
(goto-char (point-min))
(setq a (thing-at-point 'symbol))
(message "%s" a)))
#+END_SRC
see
,----[ C-h f thing-at-point RET ]
| thing-at-point is an autoloaded compiled Lisp function in
| `thingatpt.el'.
|
| (thing-at-point THING)
|
| Return the THING at point.
| THING should be a symbol specifying a type of syntactic entity.
| Possibilities include `symbol', `list', `sexp', `defun',
| `filename', `url', `email', `word', `sentence', `whitespace',
| `line', `number', and `page'.
|
| See the file `thingatpt.el' for documentation on how to define
| a symbol as a valid THING.
