There are quite few documents in which I want to update the date stamp to the last update time.
I like that #+DATE keyword value is used aptly in latex/pdf and html exports.
But I couldn't find an elegant way for that date to be updated to today's (last updated) date.
I came up with the below. But please let me know if there's an inbuilt way to do the same.
;; Update TODAY macro with current date
(defun modi/org-update-TODAY-macro (&rest ignore)
"Update TODAY macro to hold string with current date."
(when (derived-mode-p 'org-mode)
(when (looking-at ".*TODAY\\(.*\\)")
(concat " "
(format-time-string "%b %d %Y, %a" (current-time)))
:fixedcase :literal nil 1))))))
(add-hook 'org-export-before-processing-hook #'modi/org-update-TODAY-macro)
PART 2: org document where I want the #+DATE to auto update
#+MACRO: TODAY [current date is auto-inserted when exporting]
