Hi all,
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.
PART 1: Config in init.el
;; Update TODAY macro with current date
(defun modi/org-update-TODAY-macro (&rest ignore)
"Update TODAY macro to hold string with current date."
(interactive)
(when (derived-mode-p 'org-mode)
(save-excursion
(goto-char (point-min))
(while (re-search-forward
"^\\s-*#\\+MACRO:\\s-+TODAY"
nil 'noerror)
(forward-line 0)
(when (looking-at ".*TODAY\\(.*\\)")
(replace-match
(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]
#+DATE: {{{TODAY}}}

I just tested it, I get the following at the end of the exported html document: <div id="postamble" class="status"> <p class="author">Author: Suvayu Ali</p> <p class="date">Created: 2015-08-07 Fri 16:14</p> <p class="validation"><a href="http://validator.w3.org/check?uri=referer">Validate</a></p> I don't know any html, were you expecting something else?
