euro 2012 games in your org-mode agenda

Things have been rather quiet at emacs-fu - reason for this is that most of my emacs hacking time has been spent on mu4e, the emacs e-mail client I wrote. It's been shaping up pretty nicely, I should probably write some emacs-fu posts about it :)

Another interesting pastime (esp. in Europe) is football/soccer, in particular the Euro2012 games; long-time readers will remember the schedule for world cup games; I made a new one for Euro2012: https://github.com/djcb/org-euro2012.

In order to have the games show up in your agenda, make sure the file is in your org-agenda-files. If needed, you could add it with something like this in your org-mode settings (change the directory path to wherever you have put euro2012.org):

(add-to-list 'org-agenda-files "~/org/euro2012.org")

One small issue with the schedule is that it uses the central-european summer time (UTC+2), and there is no automatic way to adjust times for the local time zone. As a work-around, Juan Pechiar provided the following function which makes it easy to update all org-timestamps in a file:

(defun update-org-hours (n)
  "Change all org-mode timestamps in the current buffer by N hours."
  (interactive "nAdd hours: ")
  (save-excursion
    (goto-char (point-min))
    (while (re-search-forward "[[<]" nil t)
      (when (org-at-timestamp-p t)
        (org-timestamp-change n 'hour)))))

Evaluate this function. After that, you can go to the file with the schedule, and give an M-x update-org-hours, provide the offset for your timezone, compared to UTC+2.

Let the games begin!
