74 ** Building and Managing Org
75 *** Generating autoloads and Compiling Org without make
77 :CUSTOM_ID: compiling-org-without-make
80 #+index: Compilation!without make
82 Compilation is optional, but you _must_ update the autoloads file
83 each time you update org, even when you run org uncompiled!
85 Starting with Org 7.9 you'll find functions for creating the
86 autoload files and do byte-compilation in =mk/org-fixup.el=. When
87 you execute the commands below, your current directory must be where
88 org has been unpacked into, in other words the file =README= should
89 be found in your current directory and the directories =lisp= and
90 =etc= should be subdirectories of it. The command =emacs= should be
91 found in your =PATH= and start the Emacs version you are using. To
92 make just the autoloads file do:
93 : emacs -batch -Q -L lisp -l ../mk/org-fixup -f org-make-autoloads
94 To make the autoloads file and byte-compile org:
95 : emacs -batch -Q -L lisp -l ../mk/org-fixup -f org-make-autoloads-compile
96 To make the autoloads file and byte-compile all of org again:
97 : emacs -batch -Q -L lisp -l ../mk/org-fixup -f org-make-autoloads-compile-force
98 If you are not using Git, you'll have to make fake version strings
99 first if =org-version.el= is not already available (if it is, you
100 could also edit the version strings there).
101 : emacs -batch -Q -L lisp -l ../mk/org-fixup \
102 : --eval '(let ((org-fake-release "7.9.1")(org-fake-git-version "7.9.1-fake"))\
103 : (org-make-autoloads))'
105 POSIX shell for its quoting. Windows =CMD.exe= has quite different
106 quoting rules and this won't work, so your other option is to start
108 : emacs -Q -L lisp -l ../mk/org-fixup
109 then paste the following into the =*scratch*= buffer
110 #+BEGIN_SRC emacs-lisp
111 (let ((org-fake-release "7.9.1")
112 (org-fake-git-version "7.9.1-fake"))
113 (org-make-autoloads))
115 position the cursor after the closing paren and press =C-j= or =C-x
116 C-e= to evaluate the form. Of course you can replace
117 =org-make-autoloads= with =org-make-autoloads-compile= or even
118 =org-make-autoloads-compile-force= if you wish with both variants.
120 For *older org versions only* (that do not yet have
121 =mk/org-fixup.el=), you can use the definitions below. To use
122 this function, adjust the variables =my/org-lisp-directory= and
123 =my/org-compile-sources= to suit your needs. If you have
124 byte-compiled org, but want to run org uncompiled again, just remove
125 all =*.elc= files in the =lisp/= directory, set
126 =my/org-compile-sources= to =nil=.

162 #+index: Initialization!Reload
164 As of Org version 6.23b (released Sunday Feb 22, 2009) there is a new
165 function to reload org files.
167 Normally you want to use the compiled files since they are faster.
168 If you update your org files you can easily reload them with

173 reload the source files instead of the compiled files with

178 that generates the error and cut and paste the resulting backtrace.
179 To switch back to the compiled version just reload again with
183 *** Check for possibly problematic old link escapes
185 :CUSTOM_ID: check-old-link-escapes
188 Starting with version 7.5 Org uses [[https://en.wikipedia.org/wiki/Percent-encoding][percent escaping]] more consistently
189 and with a modified algorithm to determine which characters to escape
192 As a side effect this modified behaviour might break existing links if
193 they contain a sequence of characters that look like a percent escape
194 (e.g. =[0-9A-Fa-f]{2}=) but are in fact not a percent escape.
196 The function below can be used to perform a preliminary check for such
197 links in an Org mode file. It will run through all links in the file
198 and issue a warning if it finds a percent escape sequence which is not
199 in old Org's list of known percent escapes.

244 =org-jump-to-child= in [[file:code/elisp/org-jump.el::(defun%20org-jump-to-child][org-jump.el]] (keybinding suggested there: =C-c o c=) interactively prompts for the title of a child node, i.e. sub-heading, of the current heading and jumps to the child node having that title (in case of ambiguity: the /last/ such node).
246 In the absence of a readily accessible structural representation of the tree outline, this is ipmlemented by walking over all child nodes and collecting their titles and their positions in the file.
248 *** Go to a heading by its ID (=CUSTOM_ID= property)
250 :CUSTOM_ID: org-jump-to-id

255 =org-jump-to-id= in [[file:code/elisp/org-jump.el::(defun%20org-jump-to-id][org-jump.el]] (keybinding suggested there: =C-c o j=) interactively prompts for the one of the =CUSTOM_ID= property values in the current document and jumps to the [first] node that has this ID.
257 This implementation works efficiently in a 5 MB org file with 100 IDs. Together with ido or helm I find it a very user-friendly way of jumping to frequently used headings.
259 I noticed that =org-babel-ref-goto-headline-id= does something similar, so maybe some code could be shared among the two functions.

390 *** Different org-cycle-level behavior
391 #+index: Cycling!behavior
394 In recent org versions, when your point (cursor) is at the end of an
395 empty header line (like after you first created the header), the TAB
396 key (=org-cycle=) has a special behavior: it cycles the headline through
397 all possible levels. However, I did not like the way it determined
398 "all possible levels," so I rewrote the whole function, along with a
399 couple of supporting functions.
401 The original function's definition of "all possible levels" was "every
402 level from 1 to one more than the initial level of the current
403 headline before you started cycling." My new definition is "every
404 level from 1 to one more than the previous headline's level." So, if
405 you have a headline at level 4 and you use ALT+RET to make a new
406 headline below it, it will cycle between levels 1 and 5, inclusive.
408 The main advantage of my custom =org-cycle-level= function is that it
409 is stateless: the next level in the cycle is determined entirely by
410 the contents of the buffer, and not what command you executed last.
411 This makes it more predictable, I hope.

641 Use the function above directly on the list. If you want to use an
642 equivalent function after =C-c ^ f=, use this one instead:

645 (defun org-sort-list-by-checkbox-type-1 ()
647 (if (looking-at org-list-full-item-re)

693 *** Manipulate hours/minutes/seconds in table formulas
694 #+index: Table!hours-minutes-seconds
695 Both Bastien and Martin Halder have posted code ([[https://orgmode.org/list/00BD91C6-C610-4CDD-B3E0-E9FECDAA372C@gmail.com][Bastien's code]] and
696 [[https://orgmode.org/list/00BD91C6-C610-4CDD-B3E0-E9FECDAA372C@gmail.com][Martin's code]]) for interpreting =dd:dd= or =dd:dd:dd= strings (where
697 "=d=" is any digit) as time values in Org-mode table formula. These
698 functions have now been wrapped up into a =with-time= macro which can
699 be used in table formula to translate table cell values to and from
700 numerical values for algebraic manipulation.
702 Here is the code implementing this macro.
703 #+begin_src emacs-lisp :results silent
704 (defun org-time-string-to-seconds (s)
705 "Convert a string HH:MM:SS to a number of seconds."
708 (string-match "\\([0-9]+\\):\\([0-9]+\\):\\([0-9]+\\)" s))
709 (let ((hour (string-to-number (match-string 1 s)))
710 (min (string-to-number (match-string 2 s)))
711 (sec (string-to-number (match-string 3 s))))
712 (+ (* hour 3600) (* min 60) sec)))
714 (string-match "\\([0-9]+\\):\\([0-9]+\\)" s))
715 (let ((min (string-to-number (match-string 1 s)))
716 (sec (string-to-number (match-string 2 s))))
718 ((stringp s) (string-to-number s))
721 (defun org-time-seconds-to-string (secs)
722 "Convert a number of seconds to a time string."
723 (cond ((>= secs 3600) (format-seconds "%h:%.2m:%.2s" secs))
724 ((>= secs 60) (format-seconds "%m:%.2s" secs))
725 (t (format-seconds "%s" secs))))
727 (defmacro with-time (time-output-p &rest exprs)
728 "Evaluate an org-table formula, converting all fields that look
729 like time data to integer seconds. If TIME-OUTPUT-P then return
730 the result as a time value."
732 (if time-output-p 'org-time-seconds-to-string 'identity)
740 (list 'with-time nil el)
741 (org-time-string-to-seconds el)))
746 Which allows the following forms of table manipulation such as adding
747 and subtracting time values.
748 : | Date | Start | Lunch | Back | End | Sum |
749 : |------------------+-------+-------+-------+-------+------|
750 : | [2011-03-01 Tue] | 8:00 | 12:00 | 12:30 | 18:15 | 9:45 |

753 and dividing time values by integers

759 : | 52:22 | 4.62 | 11:20 |
760 : #+TBLFM: $3='(with-time t (/ $1 $2))
762 *Update*: As of Org version 7.6, you can use the =T= flag (both in Calc and
763 Elisp formulas) to compute time durations. For example:
765 : | Task 1 | Task 2 | Total |
766 : |--------+--------+---------|
767 : | 35:00 | 35:00 | 1:10:00 |

790 As with Times computation, the following code allows Computation with
791 Hex values in Org-mode tables using the =with-hex= macro.
793 Here is the code implementing this macro.

821 (if hex-output-p 'org-hex-to-hex 'identity)
828 (list 'with-hex nil el)

834 Which allows the following forms of table manipulation such as adding
835 and subtracting hex values.

846 #+index: Table!Field Coordinates
849 Following are some use cases that can be implemented with the “field
850 coordinates in formulas” described in the corresponding chapter in the
851 [[https://orgmode.org/manual/References.html#References][Org manual]].
853 **** Copy a column from a remote table into a column
855 :CUSTOM_ID: field-coordinates-in-formulas-copy-col-to-col
858 current column =$3= = remote column =$2=:
859 : #+TBLFM: $3 = remote(FOO, @@#$2)
861 **** Copy a row from a remote table transposed into a column
863 :CUSTOM_ID: field-coordinates-in-formulas-copy-row-to-col
866 current column =$1= = transposed remote row =@1=:
867 : #+TBLFM: $1 = remote(FOO, @$#$@#)
871 :CUSTOM_ID: field-coordinates-in-formulas-transpose-table
876 This is more like a demonstration of using “field coordinates in formulas”
877 and is bound to be slow for large tables. See the discussion in the mailing
879 [[https://orgmode.org/list/82e274891002251643k327135aajea270914244abff7@mail.gmail.com][gmane]] or

881 For more efficient solutions see
882 [[#transpose-table][Worg]].
884 To transpose this 4x7 table
887 : | year | 2004 | 2005 | 2006 | 2007 | 2008 | 2009 |
888 : |------+------+------+------+------+------+------|
889 : | min | 401 | 501 | 601 | 701 | 801 | 901 |
890 : | avg | 402 | 502 | 602 | 702 | 802 | 902 |
891 : | max | 403 | 503 | 603 | 703 | 803 | 903 |
893 start with a 7x4 table without any horizontal line (to have filled
894 also the column header) and yet empty:
904 Then add the =TBLFM= line below. After recalculation this will end up with
907 : | year | min | avg | max |
908 : | 2004 | 401 | 402 | 403 |
909 : | 2005 | 501 | 502 | 503 |
910 : | 2006 | 601 | 602 | 603 |
911 : | 2007 | 701 | 702 | 703 |
912 : | 2008 | 801 | 802 | 803 |
913 : | 2009 | 901 | 902 | 903 |
914 : #+TBLFM: @<$<..@>$> = remote(FOO, @$#$@#)
916 The formula simply exchanges row and column numbers by taking
917 - the absolute remote row number =@$#= from the current column number =$#=
918 - the absolute remote column number =$@#= from the current row number =@#=
920 Formulas to be taken over from the remote table will have to be transformed
923 **** Dynamic variation of ranges
927 In this example all columns next to =quote= are calculated from the column
928 =quote= and show the average change of the time series =quote[year]=
929 during the period of the preceding =1=, =2=, =3= or =4= years:
931 : | year | quote | 1 a | 2 a | 3 a | 4 a |
932 : |------+-------+-------+-------+-------+-------|
933 : | 2005 | 10 | | | | |
934 : | 2006 | 12 | 0.200 | | | |
935 : | 2007 | 14 | 0.167 | 0.183 | | |
936 : | 2008 | 16 | 0.143 | 0.155 | 0.170 | |
937 : | 2009 | 18 | 0.125 | 0.134 | 0.145 | 0.158 |
938 : #+TBLFM: @I$3..@>$>=if(@# >= $#, ($2 / subscr(@-I$2..@+I$2, @# + 1 - $#)) ^ (1 / ($# - 2)) - 1, string("")) +.0; f-3
940 The important part of the formula without the field blanking is:
942 : ($2 / subscr(@-I$2..@+I$2, @# + 1 - $#)) ^ (1 / ($# - 2)) - 1
944 which is the Emacs Calc implementation of the equation
946 /AvgChange(i, a) = (quote[i] / quote[i - a]) ^ (1 / a) - 1/
948 where /i/ is the current time and /a/ is the length of the preceding period.

1263 **** Reasons why this is not put into the Org core
1265 I consider this as only a hack for several reasons:
1267 - Generalization: The existing function =org-table-move-column= could

1269 functionalities and could be used as the only function for better

1271 functions with simple modifications.
1272 - Bindings: Should be convenient for repetition like =M-<right>=.
1273 What should be bound where, what has to be left unbound?
1274 - Does not fix formulas. Could be resolved for field formulas but
1275 most probably not for column or range formulas and this can lead to
1276 confusion. AFAIK all table manipulations found in Org core fix
1278 - Completeness: Not all variations and combinations are covered yet
1279 - move, rotate with range to end, rotate with range to begin, rotate
1281 - left-right, up-down

1291 On emacs-orgmode, Ryan C. Thompson suggested this:
1294 I am using org-remember set to open a new frame when used,
1295 and the default frame size is much too large. To fix this, I have
1296 designed some advice and a custom variable to implement custom
1297 parameters for the remember frame:
1300 #+begin_src emacs-lisp
1301 (defcustom remember-frame-alist nil
1302 "Additional frame parameters for dedicated remember frame."
1306 (defadvice remember (around remember-frame-parameters activate)
1307 "Set some frame parameters for the remember frame."
1308 (let ((default-frame-alist (append remember-frame-alist
1309 default-frame-alist)))
1313 Setting remember-frame-alist to =((width . 80) (height . 15)))= give a
1314 reasonable size for the frame.

1321 Christian Moe [[https://orgmode.org/list/4E0307D5.8080105@christianmoe.com][asked]], if there is a simpler way to copy the link part
1322 of an org hyperling other than to use `C-c C-l C-a C-k C-g',
1323 which is indeed kind of cumbersome.
1325 The thread offered [[https://orgmode.org/list/871uy9ghdw.fsf@gnu.org][two ways]]:
1327 Using a [[http://www.gnu.org/software/emacs/manual/html_node/emacs/Keyboard-Macros.html][keyboard macro]]:
1328 #+begin_src emacs-lisp
1330 (lambda (&optional arg)

1341 (when (org-in-regexp org-bracket-link-regexp 1)

1345 They put the link destination on the killring and can be easily bound to a key.
1347 *** Insert link with HTML title as default description
1348 When using `org-insert-link' (`C-c C-l') it might be useful to extract contents
1349 from HTML <title> tag and use it as a default link description. Here is a way to
1352 #+begin_src emacs-lisp
1353 (require 'mm-url) ; to include mm-url-decode-entities-string
1355 (defun my-org-insert-link ()
1356 "Insert org link where default description is set to html title."
1358 (let* ((url (read-string "URL: "))
1359 (title (get-html-title-from-url url)))
1360 (org-insert-link nil url title)))
1362 (defun get-html-title-from-url (url)
1363 "Return content in <title> tag."
1364 (let (x1 x2 (download-buffer (url-retrieve-synchronously url)))
1366 (set-buffer download-buffer)

1369 (search-forward "</title>")
1370 (setq x2 (search-backward "<"))
1371 (mm-url-decode-entities-string (buffer-substring-no-properties x1 x2)))))
1374 Then just use `M-x my-org-insert-link' instead of `org-insert-link'.
1376 ** Archiving Content in Org-Mode
1378 :CUSTOM_ID: archiving
1381 *** Preserve top level headings when archiving to a file
1382 #+index: Archiving!Preserve top level headings
1385 To preserve (somewhat) the integrity of your archive structure while
1386 archiving lower level items to a file, you can use the following
1389 #+begin_src emacs-lisp
1390 (defadvice org-archive-subtree (around my-org-archive-subtree activate)
1391 (let ((org-archive-location

1394 (concat (car (split-string org-archive-location "::"))
1396 (car (org-get-outline-path)))
1397 org-archive-location)))
1401 Thus, if you have an outline structure such as...
1409 ...archiving "Subsubheading" to a new file will set the location in
1410 the new file to the top level heading:
1417 While this hack obviously destroys the outline hierarchy somewhat, it
1418 at least preserves the logic of level one groupings.
1420 A slightly more complex version of this hack will not only keep the
1421 archive organized by top-level headings, but will also preserve the

1717 Now I can use the "attach" link type, but org will ask me if I want to

1787 You can change these values by setting the variables

1789 my-org-agenda-files-by-filetag uses these two variables to determine
1790 which files to search for filetags (i.e., the larger set from which

1799 :CUSTOM_ID: set-agenda-files-by-filetag
1801 #+index: Agenda!Files
1804 It is often helpful to limit yourself to a subset of your agenda
1805 files. For instance, at work, you might want to see only files related
1806 to work (e.g., bugs, clientA, projectxyz, etc.). The FAQ has helpful
1807 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 agendacommands]]. These solutions, however, require reapplying a filter each
1808 time you call the agenda or writing several new custom agenda commands
1809 for each context. Another solution is to use directories for different
1810 types of tasks and to change your agenda files with a function that
1811 sets org-agenda-files to the appropriate directory. But this relies on
1812 hard and static boundaries between files.

2047 Here is some code I came up with some code to make it easier to
2048 customize the colors of various TODO keywords. As long as you just
2049 want a different color and nothing else, you can customize the
2050 variable org-todo-keyword-faces and use just a string color (i.e. a
2051 string of the color name) as the face, and then org-get-todo-face
2052 will convert the color to a face, inheriting everything else from
2053 the standard org-todo face.
2055 To demonstrate, I currently have org-todo-keyword-faces set to

2147 whereas before I had a tendency to forget that it was there.

2226 *** Mark heading done when all checkboxes are checked.
2228 :CUSTOM_ID: mark-done-when-all-checkboxes-checked
2233 An item consists of a list with checkboxes. When all of the
2234 checkboxes are checked, the item should be considered complete and its
2235 TODO state should be automatically changed to DONE. The code below
2236 does that. This version is slightly enhanced over the one in the
2238 https://orgmode.org/list/87r5718ytv.fsf@sputnik.localhost to
2239 reset the state back to TODO if a checkbox is unchecked.
2241 Note that the code requires that a checkbox statistics cookie (the [/]
2242 or [%] thingie in the headline - see the [[https://orgmode.org/manual/Checkboxes.html#Checkboxes][Checkboxes]] section in the
2243 manual) be present in order for it to work. Note also that it is too
2244 dumb to figure out whether the item has a TODO state in the first
2245 place: if there is a statistics cookie, a TODO/DONE state will be
2246 added willy-nilly any time that the statistics cookie is changed.

2291 ** Exporting org files
2292 *** Ignoring headlines during export
2294 :CUSTOM_ID: ignoreheadline
2296 #+index: Export!ignore headlines
2297 Sometimes users want to ignore the headline text during export like in
2298 the Beamer exporter (=ox-beamer=). In the [[https://orgmode.org/manual/Beamer-export.html#Beamer-export][Beamer exporter]] one can use
2299 the tag =ignoreheading= to disable the export of a certain headline,
2300 whilst still retaining the content of the headline. We can imitate
2301 this feature in other export backends. Note that this is not a
2302 particularly easy problem, as the Org exporter creates a static
2303 representation of section numbers, table of contents etc.
2305 Consider the following document:
2307 ,* head 1 :noexport:
2308 ,* head 2 :ignoreheading:
2310 ,* =head 4= :ignoreheading:
2313 We want to remove heading 2 and 4.
2315 There are different strategies to accomplish this:
2316 1. The best option is to remove headings tagged with =ignoreheading=
2317 before export starts. This can be accomplished with the hook
2318 =org-export-before-parsing-hook= that runs before the buffer has
2319 been parsed. In the example above, however, =head 2= would not be
2320 exported as it becomes part of =head 1= which is not exporter. To
2321 overcome this move perhaps =head 1= can be moved to the end of the
2322 buffer. An example of a hook that removes headings is before
2323 parsing is available [[https://lists.gnu.org/archive/html/emacs-orgmode/2014-03/msg01459.html][here]]. Note, this solution is compatible with
2324 /all/ export formats!
2325 2. The problem is simple when exporting to LaTeX, as the LaTeX
2326 compiler determines numbers. We can thus use
2327 =org-export-filter-headline-functions= to remove the offending
2328 headlines. One regexp-based solution that looks for the word
2329 =ignoreheading= is available on [[https://stackoverflow.com/questions/10295177/is-there-an-equivalent-of-org-modes-b-ignoreheading-for-non-beamer-documents][StackOverflow]] for both the legacy
2330 exporter Org v7 exporter and the current Org v8 exporter. Note,
2331 however, that this filter will only work with LaTeX (numbering and
2332 the table of content may break in other exporters). In the example
2333 above, this filer will work flawlessly in LaTeX, it will not work
2334 at all in HTML and it will fail to update section numbers, TOC and
2335 leave some auxiliary lines behind when exporting to plain text.
2336 3. Another solution that tries to recover the Org element
2337 representation is available [[https://lists.gnu.org/archive/html/emacs-orgmode/2014-03/msg01480.html][here]]. In the example above this filter
2338 will not remove =head 4= exporting to any backend, since verbatim
2339 strings do not retain the Org element representation. It will
2340 remove the extra heading line when exporting to plain text, but
2341 will also fail to update section numbers. It should be fairly
2342 simple to also make it work with HTML.
2344 *NOTE: another way to accomplish this behavior is to use the [[https://code.orgmode.org/bzg/org-mode/raw/master/contrib/lisp/ox-extra.el][=ox-extra.el=]] package:*
2345 To use this, add the following to your =.elisp= file:
2347 #+begin_src emacs-lisp
2348 (add-to-list 'load-path "path/to/contrib/lisp")
2350 (ox-extras-activate '(ignore-headlines))
2353 After this is added, then any headlines having an =:ignore:= tag will
2354 be omitted from the export, but their contents will be included in the
2357 *** Export Org to Org and handle includes.
2358 #+index: Export!handle includes
2359 N.B: this does not apply to the "new" export engine (>= 8.0) - the function
2360 =org-export-handle-include-files-recurse= is only available in earlier versions.
2361 There is probably a way to do the same thing in the "new" exporter but nobody
2362 has stepped up to the plate yet.
2364 Nick Dokos came up with this useful function:
2366 #+begin_src emacs-lisp
2367 (defun org-to-org-handle-includes ()
2368 "Copy the contents of the current buffer to OUTFILE,
2369 recursively processing #+INCLUDEs."
2370 (let* ((s (buffer-string))
2371 (fname (buffer-file-name))
2372 (ofname (format "%s.I.org" (file-name-sans-extension fname))))
2376 (org-export-handle-include-files-recurse)
2379 (delete-region (point-min) (point-max))
2384 *** Specifying LaTeX commands to floating environments
2386 :CUSTOM_ID: latex-command-for-floats
2389 #+index: Export!LaTeX
2390 The keyword ~placement~ can be used to specify placement options to
2391 floating environments (like =\begin{figure}= and =\begin{table}=}) in
2392 LaTeX export. Org passes along everything passed in options as long as
2393 there are no spaces. One can take advantage of this to pass other
2394 LaTeX commands and have their scope limited to the floating
2397 For example one can set the fontsize of a table different from the
2398 default normal size by putting something like =\footnotesize= right
2399 after the placement options. During LaTeX export using the
2400 ~#+ATTR_LaTeX:~ line below:
2403 ,#+ATTR_LaTeX: placement=[<options>]\footnotesize
2406 exports the associated floating environment as shown in the following
2410 \begin{table}[<options>]\footnotesize
2415 It should be noted that this hack does not work for beamer export of
2416 tables since the =table= environment is not used. As an ugly
2417 workaround, one can use the following:
2420 ,#+LATEX: {\footnotesize
2421 ,#+ATTR_LaTeX: align=rr
2428 *** Styling code sections with CSS
2430 #+index: HTML!Styling code sections with CSS
2432 Code sections (marked with =#+begin_src= and =#+end_src=) are exported
2433 to HTML using =<pre>= tags, and assigned CSS classes by their content
2434 type. For example, Perl content will have an opening tag like
2435 =<pre class="src src-perl">=. You can use those classes to add styling
2436 to the output, such as here where a small language tag is added at the
2437 top of each kind of code box:
2440 (setq org-export-html-style
2441 "<style type=\"text/css\">
2442 <!--/*--><![CDATA[/*><!--*/
2443 .src { background-color: #F5FFF5; position: relative; overflow: visible; }
2444 .src:before { position: absolute; top: -15px; background: #ffffff; padding: 1px; border: 1px solid #000000; font-size: small; }
2445 .src-sh:before { content: 'sh'; }
2446 .src-bash:before { content: 'sh'; }
2447 .src-R:before { content: 'R'; }
2448 .src-perl:before { content: 'Perl'; }
2449 .src-sql:before { content: 'SQL'; }
2450 .example { background-color: #FFF5F5; }
2455 Additionally, we use color to distinguish code output (the =.example=
2456 class) from input (all the =.src-*= classes).

2528 Coq). To use it, you need to:
2529 - set the ~coqfiles~ variable to where your source files reside;
2530 - call the function using lines of the form
2532 ,#+call: fetchsrc(f="JsSyntax", s="Inductive expr :=", e="^ *$", b=1) :results drawer :post wrap-coq(text=*this*)
2534 In this example, we look inside the file ~JsSyntax.v~ in ~coqfiles~,
2535 search for a line matching ~Inductive expr :=~, and include the
2536 fragment until the first line consisting only of white space,
2537 excluded (as ~b=1~).
2539 I use drawers to store the results to avoid a bug leading to
2540 duplication during export when the code has already been evaluated in
2541 the buffer (see [[https://orgmode.org/list/m2k3fkbxec.fsf@polytechnique.org][this thread]] for a description of the problem). This
2542 has been fixed in recent versions of org-mode, so alternative
2543 approaches are possible.
2547 *** How do I preview LaTeX fragments when in a LaTeX source block?
2549 When editing =LaTeX= source blocks, you may want to preview LaTeX fragments
2550 just like in an Org-mode buffer. You can do this by using the usual
2551 keybinding =C-c C-x C-l= after loading this snipped:
2553 #+BEGIN_SRC emacs-lisp
2554 (define-key org-src-mode-map "\C-c\C-x\C-l" 'org-edit-preview-latex-fragment)
2556 (defun org-edit-preview-latex-fragment ()
2557 "Write latex fragment from source to parent buffer and preview it."
2559 (org-src-in-org-buffer (org-preview-latex-fragment)))
2562 Thanks to Sebastian Hofer for sharing this.
2564 * Hacking Org: Working with Org-mode and other Emacs Packages
2565 ** How to ediff folded Org files
2566 A rather often quip among Org users is when looking at chages with
2567 ediff. Ediff tends to fold the Org buffers when comparing. This can
2568 be very inconvenient when trying to determine what changed. A recent
2569 discussion on the mailing list led to a [[https://orgmode.org/list/87wqo5fnxc.dlv@debian.org][neat solution]] from Ratish
2572 ** org-remember-anything
2574 #+index: Remember!Anything
2576 [[http://www.emacswiki.org/cgi-bin/wiki/Anything][Anything]] users may find the snippet below interesting:
2578 #+BEGIN_SRC emacs-lisp
2579 (defvar org-remember-anything
2580 '((name . "Org Remember")
2581 (candidates . (lambda () (mapcar 'car org-remember-templates)))
2582 (action . (lambda (name)
2583 (let* ((orig-template org-remember-templates)
2584 (org-remember-templates
2585 (list (assoc name orig-template))))
2586 (call-interactively 'org-remember))))))
2589 You can add it to your 'anything-sources' variable and open remember directly
2590 from anything. I imagine this would be more interesting for people with many
2591 remember templates, so that you are out of keys to assign those to.
2593 ** Org-mode and saveplace.el
2595 Fix a problem with =saveplace.el= putting you back in a folded position:
2597 #+begin_src emacs-lisp
2598 (add-hook 'org-mode-hook
2600 (when (outline-invisible-p)
2602 (outline-previous-visible-heading 1)
2603 (org-show-subtree)))))
2606 ** Using ido-mode for org-refile (and archiving via refile)
2608 First set up ido-mode, for example using:
2610 #+begin_src emacs-lisp
2611 ; use ido mode for completion
2612 (setq ido-everywhere t)
2613 (setq ido-enable-flex-matching t)
2614 (setq ido-max-directory-size 100000)
2615 (ido-mode (quote both))
2618 Now to enable it in org-mode, use the following:
2619 #+begin_src emacs-lisp
2620 (setq org-completion-use-ido t)
2621 (setq org-refile-use-outline-path nil)
2622 (setq org-refile-allow-creating-parent-nodes 'confirm)
2624 The last line enables the creation of nodes on the fly.
2626 If you refile into files that are not in your agenda file list, you can add them as target like this (replace file1\_done, etc with your files):
2627 #+begin_src emacs-lisp
2628 (setq org-refile-targets '((org-agenda-files :maxlevel . 5) (("~/org/file1_done" "~/org/file2_done") :maxlevel . 5) ))
2631 For refiling it is often not useful to include targets that have a DONE state. It's easy to remove them by using the verify-refile-target hook.
2632 #+begin_src emacs-lisp
2633 ; Exclude DONE state tasks from refile targets; taken from http://doc.norang.ca/org-mode.html
2634 ; added check to only include headlines, e.g. line must have at least one child
2635 (defun my/verify-refile-target ()
2636 "Exclude todo keywords with a DONE state from refile targets"
2637 (or (not (member (nth 2 (org-heading-components)) org-done-keywords)))
2638 (save-excursion (org-goto-first-child))
2640 (setq org-refile-target-verify-function 'my/verify-refile-target)
2642 Now when looking for a refile target, you can use the full power of ido to find them. Ctrl-R can be used to switch between different options that ido offers.
2644 ** Using ido-completing-read to find attachments
2646 #+index: Attachment!ido completion
2650 Org-attach is great for quickly linking files to a project. But if you
2651 use org-attach extensively you might find yourself wanting to browse
2652 all the files you've attached to org headlines. This is not easy to do
2653 manually, since the directories containing the files are not human
2654 readable (i.e., they are based on automatically generated ids). Here's
2655 some code to browse those files using ido (obviously, you need to be
2658 #+begin_src emacs-lisp
2659 (load-library "find-lisp")
2661 ;; Adapted from http://www.emacswiki.org/emacs/RecentFiles
2663 (defun my-ido-find-org-attach ()
2664 "Find files in org-attachment directory"
2666 (let* ((enable-recursive-minibuffers t)
2667 (files (find-lisp-find-files org-attach-directory "."))
2670 (cons (file-name-nondirectory x)
2674 (remove-duplicates (mapcar #'car file-assoc-list)
2676 (filename (ido-completing-read "Org attachments: " filename-list nil t))
2677 (longname (cdr (assoc filename file-assoc-list))))
2678 (ido-set-current-directory
2679 (if (file-directory-p longname)
2681 (file-name-directory longname)))
2682 (setq ido-exit 'refresh
2683 ido-text-init ido-text
2687 (add-hook 'ido-setup-hook 'ido-my-keys)
2689 (defun ido-my-keys ()
2690 "Add my keybindings for ido."
2691 (define-key ido-completion-map (kbd "C-;") 'my-ido-find-org-attach))
2694 To browse your org attachments using ido fuzzy matching and/or the
2695 completion buffer, invoke ido-find-file as usual (=C-x C-f=) and then
2698 ** Link to Gnus messages by Message-Id
2699 #+index: Link!Gnus message by Message-Id
2700 In a [[https://orgmode.org/list/871vy3tg9x.fsf@wolfram.com][recent thread]] on the Org-Mode mailing list, there was some
2701 discussion about linking to Gnus messages without encoding the folder
2702 name in the link. The following code hooks in to the store-link
2703 function in Gnus to capture links by Message-Id when in nnml folders,
2704 and then provides a link type "mid" which can open this link. The
2705 =mde-org-gnus-open-message-link= function uses the
2706 =mde-mid-resolve-methods= variable to determine what Gnus backends to
2707 scan. It will go through them, in order, asking each to locate the
2708 message and opening it from the first one that reports success.
2710 It has only been tested with a single nnml backend, so there may be
2711 bugs lurking here and there.
2713 The logic for finding the message was adapted from [[http://www.emacswiki.org/cgi-bin/wiki/FindMailByMessageId][an Emacs Wiki

2849 ** Send html messages and attachments with Wanderlust
2852 /Note/: The module [[file:org-contrib/org-mime.org][Org-mime]] in Org's contrib directory provides
2853 similar functionality for both Wanderlust and Gnus. The hack below is
2854 still somewhat different: It allows you to toggle sending of html
2855 messages within Wanderlust transparently. I.e. html markup of the
2856 message body is created right before sending starts.
2858 *** Send HTML message
2860 Putting the code below in your .emacs adds following four functions:
2862 - dmj/wl-send-html-message
2864 Function that does the job: Convert everything between "--text
2865 follows this line--" and first mime entity (read: attachment) or
2866 end of buffer into html markup using `org-export-region-as-html'
2867 and replaces original body with a multipart MIME entity with the
2868 plain text version of body and the html markup version. Thus a
2869 recipient that prefers html messages can see the html markup,
2870 recipients that prefer or depend on plain text can see the plain
2873 Cannot be called interactively: It is hooked into SEMI's
2874 `mime-edit-translate-hook' if message should be HTML message.
2876 - dmj/wl-send-html-message-draft-init
2878 Cannot be called interactively: It is hooked into WL's
2879 `wl-mail-setup-hook' and provides a buffer local variable to
2882 - dmj/wl-send-html-message-draft-maybe
2884 Cannot be called interactively: It is hooked into WL's
2885 `wl-draft-send-hook' and hooks `dmj/wl-send-html-message' into
2886 `mime-edit-translate-hook' depending on whether HTML message is
2889 - dmj/wl-send-html-message-toggle
2891 Toggles sending of HTML message. If toggled on, the letters
2892 "HTML" appear in the mode line.
2894 Call it interactively! Or bind it to a key in `wl-draft-mode'.
2896 If you have to send HTML messages regularly you can set a global
2897 variable `dmj/wl-send-html-message-toggled-p' to the string "HTML" to
2898 toggle on sending HTML message by default.
2900 The image [[http://s11.directupload.net/file/u/15851/48ru5wl3.png][here]] shows an example of how the HTML message looks like in
2901 Google's web front end. As you can see you have the whole markup of
2902 Org at your service: *bold*, /italics/, tables, lists...
2904 So even if you feel uncomfortable with sending HTML messages at least
2905 you send HTML that looks quite good.

2982 *** Attach HTML of region or subtree

2986 non-proportional fonts in their mail program that messes up pretty
2989 This short function does the trick: It exports region or subtree to
2990 HTML, prefixes it with a MIME entity delimiter and pushes to killring
2991 and clipboard. If a region is active, it uses the region, the
2992 complete subtree otherwise.

3022 *** Adopting for Gnus
3024 The whole magic lies in the special strings that mark a HTML
3025 attachment. So you might just have to find out what these special
3026 strings are in message-mode and modify the functions accordingly.
3027 ** Add sunrise/sunset times to the agenda.
3028 #+index: Agenda!Diary s-expressions
3031 The diary package provides the function =diary-sunrise-sunset= which can be used
3032 in a diary s-expression in some agenda file like this:
3035 %%(diary-sunrise-sunset)
3038 Seb Vauban asked if it is possible to put sunrise and sunset in
3039 separate lines. Here is a hack to do that. It adds two functions (they
3040 have to be available before the agenda is shown, so I add them early
3041 in my org-config file which is sourced from .emacs, but you'll have to
3042 suit yourself here) that just parse the output of
3043 diary-sunrise-sunset, instead of doing the right thing which would be
3044 to take advantage of the data structures that diary/solar.el provides.
3045 In short, a hack - so perfectly suited for inclusion here :-)
3047 The functions (and latitude/longitude settings which you have to modify for
3048 your location) are as follows:
3050 #+begin_src emacs-lisp
3051 (setq calendar-latitude 48.2)
3052 (setq calendar-longitude 16.4)
3053 (setq calendar-location-name "Vienna, Austria")
3055 (autoload 'solar-sunrise-sunset "solar.el")
3056 (autoload 'solar-time-string "solar.el")
3057 (defun diary-sunrise ()
3058 "Local time of sunrise as a diary entry.
3059 The diary entry can contain `%s' which will be replaced with
3060 `calendar-location-name'."
3061 (let ((l (solar-sunrise-sunset date)))
3064 (if (string= entry "")
3066 (format entry (eval calendar-location-name))) " "
3067 (solar-time-string (caar l) nil)))))
3069 (defun diary-sunset ()
3070 "Local time of sunset as a diary entry.
3071 The diary entry can contain `%s' which will be replaced with
3072 `calendar-location-name'."
3073 (let ((l (solar-sunrise-sunset date)))
3076 (if (string= entry "")
3078 (format entry (eval calendar-location-name))) " "
3079 (solar-time-string (caadr l) nil)))))
3082 You also need to add a couple of diary s-expressions in one of your agenda
3086 %%(diary-sunrise)Sunrise in %s
3090 This will show sunrise with the location and sunset without it.
3092 The thread on the mailing list that started this can be found [[https://orgmode.org/list/87oc5rlwc4.wl%lists@700c.org][here]].
3093 In comparison to the version posted on the mailing list, this one
3094 gets rid of the timezone information and can show the location.

3099 Emacs comes with =lunar.el= to display the lunar phases (=M-x lunar-phases=).
3100 This can be used to display lunar phases in the agenda display with the
3103 #+begin_src emacs-lisp
3106 (org-no-warnings (defvar date))
3107 (defun org-lunar-phases ()
3108 "Show lunar phase in Agenda buffer."
3110 (let* ((phase-list (lunar-phase-list (nth 0 date) (nth 2 date)))
3111 (phase (cl-find-if (lambda (phase) (equal (car phase) date))
3114 (setq ret (concat (lunar-phase-name (nth 2 phase)) " "
3115 (substring (nth 1 phase) 0 5))))))
3118 Add the following line to an agenda file:
3123 %%(org-lunar-phases)
3126 This should display an entry on new moon, first/last quarter moon, and on full
3127 moon. You can customize the entries by customizing =lunar-phase-names=.
3129 E.g., to add Unicode symbols:
3131 #+begin_src emacs-lisp
3132 (setq lunar-phase-names
3133 '("● New Moon" ; Unicode symbol: 🌑 Use full circle as fallback
3134 "☽ First Quarter Moon"
3135 "○ Full Moon" ; Unicode symbol: 🌕 Use empty circle as fallback
3136 "☾ Last Quarter Moon"))
3139 Unicode 6 even provides symbols for the Moon with nice faces. But those
3140 symbols are currently barely supported in fonts.

3149 ** Calculating date differences - how to write a simple elisp function
3150 #+index: Timestamp!date calculations
3151 #+index: Elisp!technique
3153 Alexander Wingård asked how to calculate the number of days between a
3154 time stamp in his org file and today (see
3155 https://orgmode.org/list/064758C1-8D27-4647-A3C2-AB35FB8C6215@gmail.com Although the
3156 resulting answer is probably not of general interest, the method might
3157 be useful to a budding Elisp programmer.
3159 Alexander started from an already existing org function,
3160 =org-evaluate-time-range=. When this function is called in the context
3161 of a time range (two time stamps separated by "=--="), it calculates the
3162 number of days between the two dates and outputs the result in Emacs's
3163 echo area. What he wanted was a similar function that, when called from
3164 the context of a single time stamp, would calculate the number of days
3165 between the date in the time stamp and today. The result should go to
3166 the same place: Emacs's echo area.
3168 The solution presented in the mail thread is as follows:
3170 #+begin_src emacs-lisp
3171 (defun aw/org-evaluate-time-range (&optional to-buffer)
3173 (if (org-at-date-range-p t)
3174 (org-evaluate-time-range to-buffer)
3175 ;; otherwise, make a time range in a temp buffer and run o-e-t-r there
3176 (let ((headline (buffer-substring (point-at-bol) (point-at-eol))))
3179 (goto-char (point-at-bol))
3180 (re-search-forward org-ts-regexp (point-at-eol) t)
3181 (if (not (org-at-timestamp-p t))
3182 (error "No timestamp here"))
3183 (goto-char (match-beginning 0))
3184 (org-insert-time-stamp (current-time) nil nil)
3186 (org-evaluate-time-range to-buffer)))))
3189 The function assumes that point is on some line with some time stamp
3190 (or a date range) in it. Note that =org-evaluate-time-range= does not care
3191 whether the first date is earlier than the second: it will always output
3192 the number of days between the earlier date and the later date.
3194 As stated before, the function itself is of limited interest (although
3195 it satisfied Alexander's need).The *method* used might be of wider
3196 interest however, so here is a short explanation.
3198 The idea is that we want =org-evaluate-time-range= to do all the
3199 heavy lifting, but that function requires that it be in a date-range
3200 context. So the function first checks whether it's in a date range
3201 context already: if so, it calls =org-evaluate-time-range= directly
3202 to do the work. The trick now is to arrange things so we can call this
3203 same function in the case where we do *not* have a date range
3204 context. In that case, we manufacture one: we create a temporary
3205 buffer, copy the line with the purported time stamp to the temp
3206 buffer, find the time stamp (signal an error if no time stamp is
3207 found) and insert a new time stamp with the current time before the
3208 existing time stamp, followed by "=--=": voilà, we now have a time range
3209 on which we can apply our old friend =org-evaluate-time-range= to
3210 produce the answer. Because of the above-mentioned property
3211 of =org-evaluate-time-range=, it does not matter if the existing
3212 time stamp is earlier or later than the current time: the correct
3213 number of days is output.
3215 Note that at the end of the call to =with-temp-buffer=, the temporary
3216 buffer goes away. It was just used as a scratch pad for the function
3217 to do some figuring.
3219 The idea of using a temp buffer as a scratch pad has wide
3220 applicability in Emacs programming. The rest of the work is knowing
3221 enough about facilities provided by Emacs (e.g. regexp searching) and
3222 by Org (e.g. checking for time stamps and generating a time stamp) so
3223 that you don't reinvent the wheel, and impedance-matching between the
3226 ** ibuffer and org files
3228 Neil Smithline posted this snippet to let you browse org files with
3231 #+BEGIN_SRC emacs-lisp
3234 (defun org-ibuffer ()
3235 "Open an `ibuffer' window showing only `org-mode' buffers."
3237 (ibuffer nil "*Org Buffers*" '((used-mode . org-mode))))

3246 ** poporg.el: edit comments in org-mode
3248 [[https://github.com/QBobWatson/poporg/blob/master/poporg.el][poporg.el]] is a library by François Pinard which lets you edit comments
3249 and strings from your code using a separate org-mode buffer.
3251 ** Convert a .csv file to an Org-mode table
3253 Nicolas Richard has a [[https://orgmode.org/list/87a9rpy1x2.fsf@yahoo.fr][nice recipe]] using the pcsv library ([[http://marmalade-repo.org/packages/pcsv][available]] from
3254 the Marmelade ELPA repository):
3256 #+BEGIN_SRC emacs-lisp
3257 (defun yf/lisp-table-to-org-table (table &optional function)
3258 "Convert a lisp table to `org-mode' syntax, applying FUNCTION to each of its elements.
3259 The elements should not have any more newlines in them after
3260 applying FUNCTION ; the default converts them to spaces. Return
3261 value is a string containg the unaligned `org-mode' table."
3262 (unless (functionp function)
3263 (setq function (lambda (x) (replace-regexp-in-string "\n" " " x))))
3264 (mapconcat (lambda (x) ; x is a line.
3265 (concat "| " (mapconcat function x " | ") " |"))
3268 (defun yf/csv-to-table (beg end)
3269 "Convert a csv file to an `org-mode' table."
3272 (insert (yf/lisp-table-to-org-table (pcsv-parse-region beg end)))
3273 (delete-region beg end)
3277 ** Don't let visual-line-mode shadow org special commands
3279 =M-x visual-line-mode RET= will use ~beginning-of-visual-line~,
3280 ~end-of-visual-line~, and ~kill-visual-line~ instead of
3281 ~org-beginning-of-line~, ~org-end-of-line~, and ~org-kill-line~, while
3282 those might be preferred in an Org buffer.
3284 To avoid this, you can use this hack:
3286 #+begin_src emacs-lisp
3287 (add-hook 'visual-line-mode-hook
3288 (lambda () (when (derived-mode-p 'org-mode)
3289 (local-set-key (kbd "C-a") #'org-beginning-of-line)
3290 (local-set-key (kbd "C-e") #'org-end-of-line)
3291 (local-set-key (kbd "C-k") #'org-kill-line))))
3294 See [[https://orgmode.org/list/87zh7jfyal.fsf@gmail.com/][this discussion]].
3298 ~foldout.el~, which is part of Emacs, is a nice little companion for
3299 ~outline-mode~. With ~foldout.el~ one can narrow to a subtree and
3300 later unnarrow. ~foldout.el~ is useful for Org mode out of the box.
3302 There is one annoyance though (at least for me):
3303 ~foldout-zoom-subtree~ opens the drawers.
3305 This can be fixed e.g. by using the following slightly modified
3306 version of ~foldout-zoom-subtree~ which uses function ~org-show-entry~
3307 instead of ~outline-show-entry~.
3309 #+begin_src emacs-lisp
3310 (defun foldout-zoom-org-subtree (&optional exposure)
3311 "Same as `foldout-zoom-subtree' with often nicer zoom in Org mode."
3314 (((symbol-function #'outline-show-entry) (lambda () (org-show-entry))))
3315 (foldout-zoom-subtree exposure)))

3452 I often find it useful to generate Org-mode tables on the command line

3455 arguments are interpreted as rows at which to insert hlines.
3457 Here are two usage examples.
3458 1. running the following
3459 : $ cat <<EOF|~/src/config/bin/txt2org
3471 2. and the following (notice the command line argument)

3562 As of 2010-08-14, MathJax is the default method used to export math to HTML.
3564 If you like the results but do not want JavaScript in the exported pages,
3565 check out [[http://www.jboecker.de/2010/08/15/staticmathjax.html][Static MathJax]], a XULRunner application which generates a static
3566 HTML file from the exported version. It can also embed all referenced fonts
3567 within the HTML file itself, so there are no dependencies to external files.
3569 The download archive contains an elisp file which integrates it into the Org
3570 export process (configurable per file with a "#+StaticMathJax:" line).
3572 Read README.org and the comments in org-static-mathjax.el for usage instructions.

3578 list thread]] contains a (partial) Javascript solution.
3580 Note that the Javascript depends on the default HTML structure
3581 generated by Org at the time (the maint branch somewhere between 9.3
3582 and 9.4), so the code won't work without modification if you customize

3643 I struggle to keep (in emacs) a window with the agenda at all times.
3644 For a long time I have wanted a sticky window that keeps this
3645 information, and then use my window manager to place it and remove its

3668 ** Script (thru procmail) to output emails to an Org file
3669 #+index: Conversion!email to org file
3670 Tycho Garen sent [[http://comments.gmane.org/gmane.emacs.orgmode/44773][this]]:
3672 : I've [...] created some procmail and shell glue that takes emails and
3673 : inserts them into an org-file so that I can capture stuff on the go using
3674 : the email program.
3676 Everything is documented [[http://tychoish.com/code/org-mail/][here]].
3678 ** Save File With Different Format for Headings (fileconversion)
3680 :CUSTOM_ID: fileconversion
3682 #+index: Conversion!fileconversion
3684 Using hooks and on the fly
3685 - When writing a buffer to the file: Replace the leading stars from
3686 headings with a file char.
3687 - When reading a file into the buffer: Replace the file chars with
3688 leading stars for headings.
3690 To change the file format just add or remove the keyword in the
3691 ~#+STARTUP:~ line in the Org buffer and save.
3693 Now you can also change to Fundamental mode to see how the file looks
3694 like on the level of the file, can go back to Org mode, reenter Org
3695 mode or change to any other major mode and the conversion gets done
3698 *** Headings Without Leading Stars (hidestarsfile and nbspstarsfile)
3700 :CUSTOM_ID: hidestarsfile
3702 #+index: Conversion!fileconversion hidestarsfile
3704 This is like "a cleaner outline view":
3705 https://orgmode.org/manual/Clean-view.html
3707 Example of the *file content* first with leading stars as usual and
3708 below without leading stars through ~#+STARTUP: odd hidestars
3712 ,#+STARTUP: odd hidestars
3724 ,#+STARTUP: odd hidestars hidestarsfile
3735 The latter is convenient for better human readability when an Org file,
3736 additionally to Emacs, is read with a file viewer or, for smaller edits,
3737 with an editor not capable of the Org file format.
3739 ~hidestarsfile~ is a hack and can not become part of the Org core:
3740 - An Org file with ~hidestarsfile~ can not contain list items with a
3741 star as bullet due to the syntax conflict at read time. Mark
3742 E. Shoulson suggested to use the non-breaking space which is now
3743 implemented in fileconversion as ~nbspstarsfile~ as an alternative
3744 for ~hidestarsfile~. Although I don't recommend it because an editor
3745 like typically e. g. Emacs may render the non-breaking space
3746 differently from the space ~0x20~.
3747 - An Org file with ~hidestarsfile~ can almost not be edited with an
3748 Org mode without added functionality of hidestarsfile as long as the
3749 file is not converted back.
3751 *** Headings in Markdown Format (markdownstarsfile)
3753 :CUSTOM_ID: markdownstarsfile
3755 #+index: Conversion!fileconversion markdownstarsfile
3757 Together with ~oddeven~ you can use ~markdownstarsfile~ to be readable
3758 or even basically editable with Markdown (does not make much sense
3759 with ~odd~, see ~org-convert-to-odd-levels~ and
3760 ~org-convert-to-oddeven-levels~ for how to convert).
3762 Example of the *file content*:
3765 ,#+STARTUP: oddeven markdownstarsfile
3767 1. first item of numbered list (same format in Org and Markdown)
3769 - first item of unordered list (same format in Org and Markdown)
3771 + first item of unordered list (same format in Org and Markdown)
3772 #### section level 4
3773 * first item of unordered list (same format in Org and Markdown)
3774 * avoid this item type to be compatible with Org hidestarsfile
3777 An Org file with ~markdownstarsfile~ can not contain code comment
3778 lines prefixed with ~#~, even not when within source blocks.

3959 ** Meaningful diff for org files in a git repository
3960 #+index: git!diff org files
3961 Since most diff utilities are primarily meant for source code, it is
3962 difficult to read diffs of text files like ~.org~ files easily. If you
3963 version your org directory with a SCM like git you will know what I
3964 mean. However for git, there is a way around. You can use
3965 =gitattributes= to define a custom diff driver for org files. Then a
3966 regular expression can be used to configure how the diff driver
3967 recognises a "function".
3969 Put the following in your =<org_dir>/.gitattributes=.
3971 Then put the following lines in =<org_dir>/.git/config=
3973 : xfuncname = "^(\\*+ [a-zA-Z0-9]+.+)$"
3975 This will let you see diffs for org files with each hunk identified by
3976 the unmodified headline closest to the changes. After the
3977 configuration a diff should look something like the example below.
3980 diff --git a/org-hacks.org b/org-hacks.org

4014 ** Memacs - Org-mode collecting meta-data from the disk and cloud
4016 Karl Voit designed Memacs ([[https://en.wikipedia.org/wiki/Memex][Memex]] and Emacs) which is a collection of
4017 modules that are able to get meta-data from different kind of
4018 sources. Memacs then generates output files containing meta-data in
4019 Org-mode format. Those files a most likely integrated as ~*.org_archive~
4020 files in your agenda.
4022 This way, you can get a pretty decent overview of your (digital) life:
4023 - file name timestamps ([[https://en.wikipedia.org/wiki/Iso_date][ISO 8601]]; like "2013-10-11 Product Demonstration.odp")
4024 - emails (IMAP, POP, Maildir, mbox)
4025 - RSS feeds (blog updates, ... *lots* of possibilities there!)
4026 - version system commits (SVN, git)
4027 - calendar (iCal, CSV)
4028 - text messages from your phone (Android)
4029 - phone calls (Android)
4030 - photographs (EXIF)
4031 - bank accounts ([[http://easybank.at][easybank]])
4032 - usenet postings (slrn, mbox, ...)
4033 - XML (a sub-set of easy-to-parse XML files can be parsed with minimal
4036 General idea: you set up the module(s) you would like to use once and
4037 they are running in the background. As long as the data source does
4038 not change, you should not have to worry about the module again.
4040 It is hard to explain the vast amount of (small) benefits you get once
4041 you have set up your Memacs modules.
4043 There is [[http://arxiv.org/abs/1304.1332][a whitepaper which describes Memacs]] and its implications.
4045 Memacs is [[https://github.com/novoid/Memacs][hosted on github]] and is written in Python.

4048 demonstrates how to write modules with very low effort. Please

4087 for brewing beer. This is again, mostly just calc functions, including
4088 hydrometer correction, abv calculation, priming sugar for a given CO_2
4089 volume, etc. More integration with org-mode should be possible: for
4090 instance it would be nice to be able to use a lookup table (of ingredients)
4091 to calculate target original gravity, IBUs, etc.
