1.1 activating Org-mode

Activation of Org-mode (external Tutorial):

(require 'org-install)
(add-to-list 'auto-mode-alist '("\\.org$" . org-mode))
(define-key global-map "\C-cl" 'org-store-link)
(define-key global-map "\C-ca" 'org-agenda)
(setq org-log-done t)
  • Org-mode minor mode (structure editing and lists) orgstruct-mode (docu)

1.2 Org-mode documentation

1.2.1 In case of Org-mode documentation does not work

For using Org-mode from a local git repository: add following to your configuration:

(add-to-list 'Info-additional-directory-list "~/.emacs.d/<YOURDIRECTORY>/org-mode/doc/")

OR: install Org-mode documentation to your system with:

cd $ORGMODEDIRECTORY && sudo make install-info

1.4.1 Creating

  • [ ] DEMO: create headings

1.4.2 Using

1.13.1 referencing example with detailed explanation

Here is another example working with tables and referencing other tables. I did this example twice: first in a column (vertical) based layout and then the very same example in a row (horizontal) based layout:

  • all formulas explained in detail:
    • @>$5=vsum(@I..@II)
      • value: 1.8
      • last row (@>) of column five ($5) is the sum of column five between first and second horizontal line (@I..@II)
    • @>$3=string("")
      • no value (empty)
      • overwrite the last row (@>) of column three ($3) with an empty string
      • otherwise it would get 1.2 times the value of corresponding column of table Income2012v as well - I chose not to want this sum in this column
    • $1='(identity remote(Income2012v, @@#$1))
      • values: Joe until sum
      • copy content of the first column of table “Income2012v” (Lisp formula ~’(identity remote(Income2012v, @@#$1))~) to the first column in this table ($1)
      • the “identity” statement prevents calc from interpreting the content
      • this is because I am too lazy to enter all names once again :-)
      • see also Org-hacks for field formulas
    • $2='(identity remote(Income2012v, @@#$3))
      • values: 10; 24; 17; 51
      • copy the content of the second column of table “Income2012v” to the second column in this table
      • you could skip this column and calculate the values of the next columns with direct references to remote(Income2012v, @@#$3) as well. However, it is more easy to compare visually if the values from 2012 are shown here as well (usability/readability)
      • note: by convention, only the values after the first horizontal line are taken
    • $3=1.2 * remote(Income2012v, @@#$3);%.1f
      • values: 12.0; 28.8; 20.4; 61.2
      • column three ($3) is 120 percent of the values of the third column of table “Income2012v” with one decimal place (;%.1f)
      • note: 61.2 (1.2 times 51) is overwritten by formula @>$3 from above
    • $5=$4-$3;%.1f
      • values: -1.0; 2.2; 0.6
      • column five ($5) is the difference between column four to column three with one decimal place

Here is another example: how to sum up the numbers of the first column so far:

NumbersSum of numbers so far
11
56
1016
5066
200266
10001266

The formular can be simplified even more by using a column formula: #+TBLFM: $2=vsum(@2$1..$-1) provides the same result as above.

  • C-c . insert active <2012-04-23 Mon> (with C-u: <2012-04-23 Mon 19:14>)
  • C-c ! insert inactive [2012-04-23 Mon] (with C-u: [2012-04-23 Mon 19:14])
  • S-RIGHT/LEFT/UP/DOWN interactively change timestamp
  • C-c < insert today
  • C-c C-o open agenda for current timestamp
  • C-c C-d insert DEADLINE
  • C-c C-s insert SCHEDULED
  • C-u C-c C-d removing DEADLINE
  • C-u C-c C-s removing SCHEDULED
  • C-c / d sparse tree with deadlines
  • DEADLINE <YYYY-MM-DD DoW +2d> defining repeated events/tasks

  • ++3m never show multiple times even if not DONE
  • .+2d/4d show up on agenda not earlier as 2 days until 4 days
  • +1w -2d repeat weekly but show not earlier as two days before
  • C-c C-x c clone (recurring) event with time-shift (org-clone-subtree-with-time-shift)
    • good idea: create recurring event and clone it with time-shift
    • this way, canceling single events or moving single events is possible
  • 13:00-15:15 or 13:00+2:15 time range
  • <2013-11-15 Fri>-<2013-11-17 Sun> date range
  • C-c C-y return time range between dates
  • UP/DOWN on time stamp start/end -> toggle active/inactive

Note: please do not use time-stamps prior to UNIX epoch which is 1970-01-01. Some systems do handle those time-stamps fine, others produce errors.
