79 function to reload org files.
81 Normally you want to use the compiled files since they are faster.
82 If you update your org files you can easily reload them with

87 reload the source files instead of the compiled files with

139 ** Easy customization of TODO colors
142 Here is some code I came up with some code to make it easier to
143 customize the colors of various TODO keywords. As long as you just
144 want a different color and nothing else, you can customize the
145 variable org-todo-keyword-faces and use just a string color (i.e. a
146 string of the color name) as the face, and then org-get-todo-face
147 will convert the color to a face, inheriting everything else from
148 the standard org-todo face.
150 To demonstrate, I currently have org-todo-keyword-faces set to
152 #+BEGIN_SRC emacs-lisp
153 (("IN PROGRESS" . "dark orange")
155 ("CANCELED" . "saddle brown"))
158 Here's the code, in a form you can put in your =.emacs=
160 #+BEGIN_SRC emacs-lisp
161 (eval-after-load 'org-faces
163 (defcustom org-todo-keyword-faces nil
164 "Faces for specific TODO keywords.
165 This is a list of cons cells, with TODO keywords in the car and
166 faces in the cdr. The face can be a symbol, a color, or a
167 property list of attributes, like (:foreground \"blue\" :weight
173 (string :tag "Keyword")
174 (choice color (sexp :tag "Face")))))))
176 (eval-after-load 'org
178 (defun org-get-todo-face-from-color (color)
179 "Returns a specification for a face that inherits from org-todo
180 face and has the given color as foreground. Returns nil if
183 `(:inherit org-warning :foreground ,color)))

186 "Get the right face for a TODO keyword KWD.

200 Put the following in your =.emacs=, and =C-x 4 a= and other functions which
201 use =add-log-current-defun= like =magit-add-log= will pick up the nearest org
202 headline as the "current function" if you add a changelog entry from an org
205 #+BEGIN_SRC emacs-lisp

240 (push tag inherited) (push tag local)))
242 (if (member tag inherited) (org-toggle-tag tag 'off)))))
246 ** Remove empty property drawers
248 David Maus proposed this:
250 #+begin_src emacs-lisp
251 (defun dmj:org:remove-empty-propert-drawers ()
252 "*Remove all empty property drawers in current file."
254 (unless (eq major-mode 'org-mode)
255 (error "You need to turn on Org mode for this function."))
257 (goto-char (point-min))
258 (while (re-search-forward ":PROPERTIES:" nil t)
260 (org-remove-empty-drawer-at "PROPERTIES" (match-beginning 0))))))
263 ** Different org-cycle-level behavior
266 In recent org versions, when your point (cursor) is at the end of an
267 empty header line (like after you first created the header), the TAB
268 key (=org-cycle=) has a special behavior: it cycles the headline through
269 all possible levels. However, I did not like the way it determined
270 "all possible levels," so I rewrote the whole function, along with a
271 couple of supporting functions.
273 The original function's definition of "all possible levels" was "every
274 level from 1 to one more than the initial level of the current
275 headline before you started cycling." My new definition is "every
276 level from 1 to one more than the previous headline's level." So, if
277 you have a headline at level 4 and you use ALT+RET to make a new
278 headline below it, it will cycle between levels 1 and 5, inclusive.
280 The main advantage of my custom =org-cycle-level= function is that it
281 is stateless: the next level in the cycle is determined entirely by
282 the contents of the buffer, and not what command you executed last.
283 This makes it more predictable, I hope.
285 #+BEGIN_SRC emacs-lisp
288 (defun org-point-at-end-of-empty-headline ()

361 ** Add an effort estimate on the fly when clocking in
363 You can use =org-clock-in-prepare-hook= to add an effort estimate.
364 This way you can easily have a "tea-timer" for your tasks when they
365 don't already have an effort estimate.
367 #+begin_src emacs-lisp
368 (add-hook 'org-clock-in-prepare-hook
369 'my-org-mode-ask-effort)
371 (defun my-org-mode-ask-effort ()
372 "Ask for an effort estimate when clocking in."
373 (unless (org-entry-get (point) "Effort")
377 (org-entry-get-multivalued-property (point) "Effort"))))
378 (unless (equal effort "")
379 (org-set-property "Effort" effort)))))
382 Or you can use a default effort for such a timer:
384 #+begin_src emacs-lisp
385 (add-hook 'org-clock-in-prepare-hook
386 'my-org-mode-add-default-effort)
388 (defvar org-clock-default-effort "1:00")
390 (defun my-org-mode-add-default-effort ()
391 "Add a default effort estimation."
392 (unless (org-entry-get (point) "Effort")
393 (org-set-property "Effort" org-clock-default-effort)))
396 ** Customize the size of the frame for remember
399 On emacs-orgmode, Ryan C. Thompson suggested this:
402 I am using org-remember set to open a new frame when used,
403 and the default frame size is much too large. To fix this, I have
404 designed some advice and a custom variable to implement custom
405 parameters for the remember frame:
408 #+begin_src emacs-lisp
409 (defcustom remember-frame-alist nil
410 "Additional frame parameters for dedicated remember frame."
414 (defadvice remember (around remember-frame-parameters activate)
415 "Set some frame parameters for the remember frame."
416 (let ((default-frame-alist (append remember-frame-alist
417 default-frame-alist)))
421 Setting remember-frame-alist to =((width . 80) (height . 15)))= give a
422 reasonable size for the frame.
424 *** Dates computation
426 **** Question ([[http://article.gmane.org/gmane.emacs.orgmode/15692][Xin Shi]])
428 I have a table in org which stores the date, I'm wondering if there is
429 any function to calculate the duration? For example:
431 | Start Date | End Date | Duration |
432 |------------+------------+----------|
433 | 2004.08.07 | 2005.07.08 | |
435 I tried to use B&-C&, but failed ...
437 **** Answer ([[http://article.gmane.org/gmane.emacs.orgmode/15694][Nick Dokos]])
441 | Start Date | End Date | Duration |
442 |------------+------------+----------|
443 | 2004.08.07 | 2005.07.08 | 335 |
444 :#+TBLFM: $3=(date(<$2>)-date(<$1>))
448 http://thread.gmane.org/gmane.emacs.orgmode/7741
450 as well as this post (which is really a followup on the
453 http://article.gmane.org/gmane.emacs.orgmode/7753
455 The problem that this last article pointed out was solved
458 http://article.gmane.org/gmane.emacs.orgmode/8001
460 and Chris Randle's original musings are at
462 http://article.gmane.org/gmane.emacs.orgmode/6536/
464 *** Field coordinates in formulas (=@#= and =$#=)
468 Following are some use cases that can be implemented with the
469 _field coordinates in formulas_ described in the corresponding
470 chapter in the [[http://orgmode.org/manual/References.html#References][Org manual]], available since =org-version= 6.35.
472 **** Copy a column from a remote table into a column
474 current column =$3= = remote column =$2=:
475 : #+TBLFM: $3 = remote(FOO, @@#$2)
477 **** Copy a row from a remote table transposed into a column
479 current column =$1= = transposed remote row =@1=:
480 : #+TBLFM: $1 = remote(FOO, @$#$@#)
482 **** Transpose a table
486 This is more like a demonstration of using _field coordinates in formulas_
487 to [[http://en.wikipedia.org/wiki/Transpose][transpose]] a table or to do it without using org-babel. The efficient
488 and simple solution for this with the help of org-babel and Emacs Lisp has
489 been provided by Thomas S. Dye on the [[http://thread.gmane.org/gmane.emacs.orgmode/23809/focus=23815][mailing list]].
491 To transpose this 4x7 table
494 : | year | 2004 | 2005 | 2006 | 2007 | 2008 | 2009 |
495 : |------+------+------+------+------+------+------|
496 : | min | 401 | 501 | 601 | 701 | 801 | 901 |
497 : | avg | 402 | 502 | 602 | 702 | 802 | 902 |
498 : | max | 403 | 503 | 603 | 703 | 803 | 903 |
500 start with a 7x4 table without any horizontal line (to have filled
501 also the column header) and yet empty:
511 Then add the =TBLFM= below with the same formula repeated for each column.
512 After recalculation this will end up with the transposed copy:
514 : | year | min | avg | max |
515 : | 2004 | 401 | 402 | 403 |
516 : | 2005 | 501 | 502 | 503 |
517 : | 2006 | 601 | 602 | 603 |
518 : | 2007 | 701 | 702 | 703 |
519 : | 2008 | 801 | 802 | 803 |
520 : | 2009 | 901 | 902 | 903 |
521 : #+TBLFM: $1 = remote(FOO, @$#$@#) :: $2 = remote(FOO, @$#$@#) :: $3 = remote(FOO, @$#$@#) :: $4 = remote(FOO, @$#$@#)
523 The formulas simply exchange row and column numbers by taking
524 - the absolute remote row number =@$#= from the current column number =$#=
525 - the absolute remote column number =$@#= from the current row number =@#=
527 Possible field formulas from the remote table will have to be transferred
528 manually. Since there are no row formulas yet there is no need to transfer
529 column formulas to row formulas or vice versa.
531 **** Dynamic variation of ranges
535 In this example all columns next to =quote= are calculated from the column
536 =quote= and show the average change of the time series =quote[year]=
537 during the period of the preceding =1=, =2=, =3= or =4= years:
539 : | year | quote | 1 a | 2 a | 3 a | 4 a |
540 : |------+-------+-------+-------+-------+-------|
541 : | 2005 | 10 | | | | |
542 : | 2006 | 12 | 0.200 | | | |
543 : | 2007 | 14 | 0.167 | 0.183 | | |
544 : | 2008 | 16 | 0.143 | 0.155 | 0.170 | |
545 : | 2009 | 18 | 0.125 | 0.134 | 0.145 | 0.158 |
546 : #+TBLFM: $3=if(@# >= $#, ($2 / subscr(@-I$2..@+I$2, @# + 1 - $#)) ^ (1 / ($# - 2)) - 1, string("")); f3::$4=if(@# >= $#, ($2 / subscr(@-I$2..@+I$2, @# + 1 - $#)) ^ (1 / ($# - 2)) - 1, string("")); f3::$5=if(@# >= $#, ($2 / subscr(@-I$2..@+I$2, @# + 1 - $#)) ^ (1 / ($# - 2)) - 1, string("")); f3::$6=if(@# >= $#, ($2 / subscr(@-I$2..@+I$2, @# + 1 - $#)) ^ (1 / ($# - 2)) - 1, string("")); f3
548 The formula is the same for each column =$3= through =$6=. This can easily
549 be seen with the great formula editor invoked by C-c ' on the
550 table. The important part of the formula without the field blanking is:
552 : ($2 / subscr(@-I$2..@+I$2, @# + 1 - $#)) ^ (1 / ($# - 2)) - 1
554 which is the Emacs Calc implementation of the equation
556 /AvgChange(i, a) = (quote[i] / quote[i - a]) ^ 1 / n - 1/
558 where /i/ is the current time and /a/ is the length of the preceding period.

597 ** Preserve top level headings when archiving to a file
600 To preserve (somewhat) the integrity of your archive structure while
601 archiving lower level items to a file, you can use the following
604 #+begin_src emacs-lisp
605 (defadvice org-archive-subtree (around my-org-archive-subtree activate)
606 (let ((org-archive-location
607 (if (save-excursion (org-back-to-heading)
608 (> (org-outline-level) 1))
609 (concat (car (split-string org-archive-location "::"))
611 (car (org-get-outline-path)))
612 org-archive-location)))
616 Thus, if you have an outline structure such as...
624 ...archiving "Subsubheading" to a new file will set the location in
625 the new file to the top level heading:
633 While this hack obviously destroys the outline hierarchy somewhat, it
634 at least preserves the logic of level one groupings.
636 ** Promote all items in subtree

640 subtrees primarily to organize projects, the function is somewhat
641 unimaginatively called my-org-un-project:

701 (my-org-set-agenda-files)
704 The code above will set your "default" agenda files to all files
705 ending in ".org" and ".ref" in the directories "~/org/" and "~/work/".
706 You can change these values by setting the variables
707 my-org-agenda-extensions and my-org-agenda-directories. The function
708 my-org-agenda-files-by-filetag uses these two variables to determine
709 which files to search for filetags (i.e., the larger set from which
710 the subset will be drawn).
712 You can also easily use my-org-list-files to "mix and match"
713 directories and extensions to generate different lists of agenda
716 ** Restrict org-agenda-files by filetag
718 :CUSTOM_ID: set-agenda-files-by-filetag
722 It is often helpful to limit yourself to a subset of your agenda
723 files. For instance, at work, you might want to see only files related
724 to work (e.g., bugs, clientA, projectxyz, etc.). The FAQ has helpful
725 information on filtering tasks using [[file:org-faq.org::#limit-agenda-with-tag-filtering][filetags]] and [[file:org-faq.org::#limit-agenda-with-category-match][custom agenda
726 commands]]. These solutions, however, require reapplying a filter each
727 time you call the agenda or writing several new custom agenda commands
728 for each context. Another solution is to use directories for different
729 types of tasks and to change your agenda files with a function that
730 sets org-agenda-files to the appropriate directory. But this relies on
731 hard and static boundaries between files.
733 The following functions allow for a more dynamic approach to selecting
734 a subset of files based on filetags:
736 #+begin_src emacs-lisp
737 (defun my-org-agenda-restrict-files-by-filetag (&optional tag)
738 "Restrict org agenda files only to those containing filetag."
740 (let* ((tagslist (my-org-get-all-filetags))
742 (completing-read "Tag: "
743 (mapcar 'car tagslist)))))
744 (org-agenda-remove-restriction-lock 'noupdate)
745 (put 'org-agenda-files 'org-restrict (cdr (assoc ftag tagslist)))
746 (setq org-agenda-overriding-restriction 'files)))
748 (defun my-org-get-all-filetags ()
749 "Get list of filetags from all default org-files."
750 (let ((files org-agenda-files)
752 (save-window-excursion
753 (while (setq x (pop files))
754 (set-buffer (find-file-noselect x))
757 (let ((tagfiles (assoc y tagslist)))
759 (setcdr tagfiles (cons x (cdr tagfiles)))
760 (add-to-list 'tagslist (list y x)))))
761 (my-org-get-filetags)))
764 (defun my-org-get-filetags ()
765 "Get list of filetags for current buffer"
766 (let ((ftags org-file-tags)
770 (org-substring-no-properties x))
774 Calling my-org-agenda-restrict-files-by-filetag results in a prompt
775 with all filetags in your "normal" agenda files. When you select a
776 tag, org-agenda-files will be restricted to only those files
777 containing the filetag. To release the restriction, type C-c C-x >
778 (org-agenda-remove-restriction-lock).
780 ** Split horizontally for agenda
782 If you would like to split the frame into two side-by-side windows when
783 displaying the agenda, try this hack from Jan Rehders, which uses the
784 `toggle-window-split' from

799 (defvar bzg-org-clock-in-appt-delay 100
800 "Number of minutes for setting an appointment by clocking-in")
803 This function let's you add an appointment for the current entry.
804 This can be useful when you need a reminder.
806 #+BEGIN_SRC emacs-lisp
807 (defun bzg-org-clock-in-add-appt (&optional n)
808 "Add an appointment for the Org entry at point in N minutes."
811 (org-back-to-heading t)
812 (looking-at org-complex-heading-regexp)
813 (let* ((msg (match-string-no-properties 4))

819 (appt-add (format-time-string
820 "%H:%M" (apply 'encode-time appt-time)) msg)
821 (if (interactive-p) (message "New appointment for %s" msg)))))
824 You can advise =org-clock-in= so that =C-c C-x C-i= will automatically
827 #+BEGIN_SRC emacs-lisp
828 (defadvice org-clock-in (after org-clock-in-add-appt activate)
829 "Add an appointment when clocking a task in."
830 (bzg-org-clock-in-add-appt))
833 You may also want to delete the associated appointment when clocking
834 out. This function does this:
836 #+BEGIN_SRC emacs-lisp
837 (defun bzg-org-clock-out-delete-appt nil
838 "When clocking out, delete any associated appointment."
841 (org-back-to-heading t)
842 (looking-at org-complex-heading-regexp)
843 (let* ((msg (match-string-no-properties 4)))
844 (setq appt-time-msg-list
848 (if (not (string-match (regexp-quote msg)
850 appt-time-msg-list)))
854 And here is the advice for =org-clock-out= (=C-c C-x C-o=)
856 #+BEGIN_SRC emacs-lisp
857 (defadvice org-clock-out (before org-clock-out-delete-appt activate)
858 "Delete an appointment when clocking a task out."
859 (bzg-org-clock-out-delete-appt))
862 *IMPORTANT*: You can add appointment by clocking in in both an
863 =org-mode= and an =org-agenda-mode= buffer. But clocking out from
864 agenda buffer with the advice above will bring an error.
865 ** Highlight the agenda line under cursor
867 This is useful to make sure what task you are operating on.

887 ** Remove time grid lines that are in an appointment
889 The agenda shows lines for the time grid. Some people think that
890 these lines are a distraction when there are appointments at those
891 times. You can get rid of the lines which coincide exactly with the
892 beginning of an appointment. Michael Ekstrand has written a piece of
893 advice that also removes lines that are somewhere inside an

1175 I have the following snippet in my .emacs file, which I find very
1176 useful. Basically what it does is that if I don't touch my Emacs for 5
1177 minutes, it displays the current agenda. This keeps my tasks "always
1178 in mind" whenever I come back to Emacs after doing something else,
1179 whereas before I had a tendency to forget that it was there.

1214 ** Link to Gnus messages by Message-Id
1216 In a [[http://thread.gmane.org/gmane.emacs.orgmode/8860][recent thread]] on the Org-Mode mailing list, there was some
1217 discussion about linking to Gnus messages without encoding the folder
1218 name in the link. The following code hooks in to the store-link
1219 function in Gnus to capture links by Message-Id when in nnml folders,
1220 and then provides a link type "mid" which can open this link. The
1221 =mde-org-gnus-open-message-link= function uses the
1222 =mde-mid-resolve-methods= variable to determine what Gnus backends to
1223 scan. It will go through them, in order, asking each to locate the
1224 message and opening it from the first one that reports success.
1226 It has only been tested with a single nnml backend, so there may be
1227 bugs lurking here and there.

1350 ** Send html messages and attachments with Wanderlust
1353 /Note/: The module [[file:org-contrib/org-mime.org][Org-mime]] in Org's contrib directory provides
1354 similar functionality for both Wanderlust and Gnus. The hack below is
1355 still somewhat different: It allows you to toggle sending of html
1356 messages within Wanderlust transparently. I.e. html markup of the
1357 message body is created right before sending starts.
1359 *** Send HTML message
1361 Putting the code below in your .emacs adds following four functions:
1363 - dmj/wl-send-html-message
1365 Function that does the job: Convert everything between "--text
1366 follows this line--" and first mime entity (read: attachment) or
1367 end of buffer into html markup using `org-export-region-as-html'
1368 and replaces original body with a multipart MIME entity with the
1369 plain text version of body and the html markup version. Thus a
1370 recipient that prefers html messages can see the html markup,
1371 recipients that prefer or depend on plain text can see the plain
1374 Cannot be called interactively: It is hooked into SEMI's
1375 `mime-edit-translate-hook' if message should be HTML message.
1377 - dmj/wl-send-html-message-draft-init
1379 Cannot be called interactively: It is hooked into WL's
1380 `wl-mail-setup-hook' and provides a buffer local variable to
1383 - dmj/wl-send-html-message-draft-maybe
1385 Cannot be called interactively: It is hooked into WL's
1386 `wl-draft-send-hook' and hooks `dmj/wl-send-html-message' into
1387 `mime-edit-translate-hook' depending on whether HTML message is
1390 - dmj/wl-send-html-message-toggle
1392 Toggles sending of HTML message. If toggled on, the letters
1393 "HTML" appear in the mode line.
1395 Call it interactively! Or bind it to a key in `wl-draft-mode'.
1397 If you have to send HTML messages regularly you can set a global
1398 variable `dmj/wl-send-html-message-toggled-p' to the string "HTML" to
1399 toggle on sending HTML message by default.
1401 The image [[http://s11.directupload.net/file/u/15851/48ru5wl3.png][here]] shows an example of how the HTML message looks like in
1402 Google's web front end. As you can see you have the whole markup of
1403 Org at your service: *bold*, /italics/, tables, lists...
1405 So even if you feel uncomfortable with sending HTML messages at least
1406 you send HTML that looks quite good.

1483 *** Attach HTML of region or subtree

1486 of an Org file as HTML for the poor souls who are plagued with
1487 non-proportional fonts in their mail program that messes up pretty
1490 This short function does the trick: It exports region or subtree to
1491 HTML, prefixes it with a MIME entity delimiter and pushes to killring
1492 and clipboard. If a region is active, it uses the region, the
1493 complete subtree otherwise.

1523 *** Adopting for Gnus
1525 The whole magic lies in the special strings that mark a HTML
1526 attachment. So you might just have to find out what these special
1527 strings are in message-mode and modify the functions accordingly.

1656 ** Use MathJax for HTML export without requiring JavaScript
1657 As of 2010-08-14, MathJax is the default method used to export math to HTML.
1659 If you like the results but do not want JavaScript in the exported pages,
1660 check out [[http://www.jboecker.de/2010/08/15/staticmathjax.html][Static MathJax]], a XULRunner application which generates a static
1661 HTML file from the exported version. It can also embed all referenced fonts
1662 within the HTML file itself, so there are no dependencies to external files.
1664 The download archive contains an elisp file which integrates it into the Org
1665 export process (configurable per file with a "#+StaticMathJax:" line).
