1.1 Summary
|
||
===========
|
||
|
||
Org-mode is a mode for keeping notes, maintaining ToDo lists, and doing
|
||
project planning with a fast and effective plain-text system.
|
||
|
||
Org-mode develops organizational tasks around NOTES files that
|
||
contain information about projects as plain text. Org-mode is
|
||
implemented on top of outline-mode, which makes it possible to keep the
|
||
content of large files well structured. Visibility cycling and
|
||
structure editing help to work with the tree. Tables are easily
|
||
created with a built-in table editor. Org-mode supports ToDo items,
|
||
deadlines, time stamps, and scheduling. It dynamically compiles
|
||
entries into an agenda that utilizes and smoothly integrates much of
|
||
the Emacs calendar and diary. Plain text URL-like links connect to
|
||
websites, emails, Usenet messages, BBDB entries, and any files related
|
||
to the projects. For printing and sharing of notes, an Org-mode file
|
||
can be exported as a structured ASCII file, as HTML, or (todo and
|
||
agenda items only) as an iCalendar file. It can also serve as a
|
||
publishing tool for a set of linked webpages.
|
||
|
||
An important design aspect that distinguishes Org-mode from other
|
||
packages like Planner/Muse is that it encougages to store every piece of
|
||
information only once. In Planner, you have project pages, day pages
|
||
and possibly other files, duplicating some information such as tasks.
|
||
In Org-mode, you only have notes files. In your notes you mark entries
|
||
as tasks, label them with tags and timestamps. All necessary lists like
|
||
a schedule for the day, the agenda for a meeting, tasks lists selected
|
||
by tags etc are created dynamically when you need them.
|
||
|
||
Org-mode keeps simple things simple. When first fired up, it should
|
||
feel like a straightforward, easy to use outliner. Complexity is not
|
||
imposed, but a large amount of functionality is available when you need
|
||
it. Org-mode can be used on different levels and in different ways, for
|
||
example:
|
||
|
||
* as an outline extension with visibility cycling and structure editing
|
||
* as an ASCII system and table editor for taking structured notes
|
||
* as an ASCII table editor with spreadsheet-like capabilities
|
||
* as a TODO list editor
|
||
* as a full agenda and planner with deadlines and work scheduling
|
||
* as an environment to implement David Allen's GTD system
|
||
* as a simple hypertext system, with HTML export
|
||
* as a publishing tool to create a set of interlinked webpages
|
||
|
||
Org-mode's automatic, context sensitive table editor can be
|
||
integrated into any major mode by activating the minor Orgtbl-mode.
|
||
|
||
There is a website for Org-mode which provides links to the newest
|
||
version of Org-mode, as well as additional information, frequently asked
|
||
questions (FAQ), links to tutorials etc. This page is located at
|
||
`http://www.astro.uva.nl/~dominik/Tools/org/'.

File: org, Node: Installation, Next: Activation, Prev: Summary, Up: Introduction
|
||
|
||
1.2 Installation
|
||
================
|
||
|
||
Important: If Org-mode is part of the Emacs distribution or an XEmacs
|
||
package, please skip this section and go directly to *Note Activation::.
|
||
|
||
If you have downloaded Org-mode from the Web, you must take the
|
||
following steps to install it: Go into the Org-mode distribution
|
||
directory and edit the top section of the file `Makefile'. You must
|
||
set the name of the Emacs binary (likely either `emacs' or `xemacs'),
|
||
and the paths to the directories where local Lisp and Info files are
|
||
kept. If you don't have access to the system-wide directories, create
|
||
your own two directories for these files, enter them into the Makefile,
|
||
and make sure Emacs finds the Lisp files by adding the following line
|
||
to `.emacs':
|
||
|
||
(setq load-path (cons "~/path/to/lispdir" load-path))
|
||
|
||
XEmacs users now need to install the file `noutline.el' from the
|
||
`xemacs' subdirectory of the Org-mode distribution. Use the command:
|
||
|
||
make install-noutline
|
||
|
||
Now byte-compile and install the Lisp files with the shell commands:
|
||
|
||
make
|
||
make install
|
||
|
||
If you want to install the info documentation, use this command:
|
||
|
||
make install-info
|
||
|
||
Then add to `.emacs':
|
||
|
||
;; This line only if org-mode is not part of the X/Emacs distribution.
|
||
(require 'org-install)
|
||
|
||
|
||
File: org, Node: Activation, Next: Feedback, Prev: Installation, Up: Introduction
|
||
|
||
1.3 Activation
|
||
==============
|
||
|
||
Add the following lines to your `.emacs' file. The last two lines
|
||
define _global_ keys for the commands `org-store-link' and `org-agenda'
|
||
- please choose suitable keys yourself.
|
||
|
||
;; The following lines are always needed. Choose your own keys.
|
||
(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)
|
||
|
||
Furthermore, you must activate `font-lock-mode' in org-mode buffers,
|
||
because significant functionality depends on font-locking being active.
|
||
You can do this with either one of the following two lines (XEmacs
|
||
user must use the second option):
|
||
(global-font-lock-mode 1) ; for all buffers
|
||
(add-hook 'org-mode-hook 'turn-on-font-lock) ; org-mode buffers only
|
||
|
||
With this setup, all files with extension `.org' will be put into
|
||
Org-mode. As an alternative, make the first line of a file look like
|
||
this:
|
||
|
||
MY PROJECTS -*- mode: org; -*-
|
||
|
||
which will select Org-mode for this buffer no matter what the file's
|
||
name is. See also the variable `org-insert-mode-line-in-empty-file'.

1.4 Feedback
|
||
============
|
||
|
||
If you find problems with Org-mode, or if you have questions, remarks,
|
||
or ideas about it, please contact the maintainer Carsten Dominik at
|
||
<dominik@science.uva.nl>.
|
||
|
||
For bug reports, please provide as much information as possible,
|
||
including the version information of Emacs (`C-h v emacs-version
|
||
<RET>') and Org-mode (`C-h v org-version <RET>'), as well as the
|
||
Org-mode related setup in `.emacs'. If an error occurs, a traceback
|
||
can be very useful. Often a small example file helps, along with clear
|
||
information about:
|
||
|
||
1. What exactly did you do?
|
||
|
||
2. What did you expect to happen?
|
||
|
||
3. What happened instead?
|
||
Thank you for helping to improve this mode.

2.1 Outlines
|
||
============
|
||
|
||
Org-mode is implemented on top of outline-mode. Outlines allow to
|
||
organize a document in a hierarchical structure, which (at least for
|
||
me) is the best representation of notes and thoughts. Overview over
|
||
this structure is achieved by folding (hiding) large parts of the
|
||
document to show only the general document structure and the parts
|
||
currently being worked on. Org-mode greatly simplifies the use of
|
||
outlines by compressing the entire show/hide functionality into a
|
||
single command `org-cycle', which is bound to the <TAB> key.
|
||
|
||
|
||

|
||
|
||
2.2 Headlines
|
||
=============
|
||
|
||
Headlines define the structure of an outline tree. The headlines in
|
||
Org-mode start with one or more stars, on the left margin. For example:
|
||
|
||
* Top level headline
|
||
** Second level
|
||
*** 3rd level
|
||
some text
|
||
*** 3rd level
|
||
more text
|
||
* Another top level headline
|
||
|
||
Some people find the many stars too noisy and would prefer an outline
|
||
that has whitespace followed by a single star as headline starters.
|
||
*Note Clean view:: describes a setup to realize this.
|
||

|
||
|
||
2.3 Visibility cycling
|
||
======================
|
||
|
||
Outlines make it possible to hide parts of the text in the buffer.
|
||
Org-mode uses just two commands, bound to <TAB> and `S-<TAB>' to change
|
||
the visibility in the buffer.
|
||
|
||
`<TAB>'
|
||
_Subtree cycling_: Rotate current subtree between the states
|
||
|
||
,-> FOLDED -> CHILDREN -> SUBTREE --.
|
||
'-----------------------------------'
|
||
|
||
The cursor must be on a headline for this to work(1). When the
|
||
cursor is at the beginning of the buffer and the first line is not
|
||
a headline, then <TAB> actually runs global cycling (see
|
||
below)(2). Also when called with a prefix argument (`C-u <TAB>'),
|
||
global cycling is invoked.
|
||
|
||
`S-<TAB>'
|
||
`C-u <TAB>'
|
||
_Global cycling_: Rotate the entire buffer between the states
|
||
|
||
,-> OVERVIEW -> CONTENTS -> SHOW ALL --.
|
||
'--------------------------------------'
|
||
|
||
Note that inside tables, `S-<TAB>' jumps to the previous field.
|
||
|
||
`C-c C-a'
|
||
Show all.
|
||
|
||
When Emacs first visits an Org-mode file, the global state is set to
|
||
OVERVIEW, i.e. only the top level headlines are visible. This can be
|
||
configured through the variable `org-startup-folded', or on a per-file
|
||
basis by adding one of the following lines anywhere in the buffer:
|
||
|
||
#+STARTUP: overview
|
||
#+STARTUP: content
|
||
#+STARTUP: showall
|
||
|
||
---------- Footnotes ----------
|
||
|
||
(1) see, however, the option `org-cycle-emulate-tab'.
|
||
|
||
(2) see the option `org-cycle-global-at-bob'.

2.4 Motion
|
||
==========
|
||
|
||
The following commands jump to other headlines in the buffer.
|
||
|
||
`C-c C-n'
|
||
Next heading.
|
||
|
||
`C-c C-p'
|
||
Previous heading.
|
||
|
||
`C-c C-f'
|
||
Next heading same level.
|
||
|
||
`C-c C-b'
|
||
Previous heading same level.

||
|
||
`C-c C-u'
|
||
Backward to higher level heading.
|
||
|
||
`C-c C-j'
|
||
Jump to a different place without changing the current outline
|
||
visibility. Shows the document structure in a temporary buffer,
|
||
where you can use visibility cycling (<TAB>) to find your
|
||
destination. After pressing <RET>, the cursor moves to the
|
||
selected location in the original buffer, and the headings
|
||
hierarchy above it is made visible.

2.5 Structure editing
|
||
=====================
|
||
|
||
`M-<RET>'
|
||
Insert new heading with same level as current. If the cursor is
|
||
in a plain list item, a new item is created (*note Plain lists::).
|
||
To force creation of a new headline, use a prefix arg, or first
|
||
press <RET> to get to the beginning of the next line. When this
|
||
command is used in the middle of a line, the line is split and the
|
||
rest of the line becomes the new headline. If the command is used
|
||
at the beginning of a headline, the new headline is created before
|
||
the current line. If at the beginning of any other line, the
|
||
content of that line is made the new heading. If the command is
|
||
used at the end of a folded subtree (i.e. behind the ellipses at
|
||
the end of a headline), then a headline like the current one will
|
||
be inserted after the end of the subtree.
|
||
|
||
`M-S-<RET>'
|
||
Insert new TODO entry with same level as current heading.
|
||
|
||
`M-<left>'
|
||
Promote current heading by one level.
|
||
|
||
`M-<right>'
|
||
Demote current heading by one level.
|
||
|
||
`M-S-<left>'
|
||
Promote the current subtree by one level.
|
||
|
||
`M-S-<right>'
|
||
Demote the current subtree by one level.
|
||
|
||
`M-S-<up>'
|
||
Move subtree up (swap with previous subtree of same level).
|
||
|
||
`M-S-<down>'
|
||
Move subtree down (swap with next subtree of same level).
|
||
|
||
`C-c C-x C-w'
|
||
`C-c C-x C-k'
|
||
Kill subtree, i.e. remove it from buffer but save in kill ring.
|
||
|
||
`C-c C-x M-w'
|
||
Copy subtree to kill ring.
|
||
|
||
`C-c C-x C-y'
|
||
Yank subtree from kill ring. This does modify the level of the
|
||
subtree to make sure the tree fits in nicely at the yank position.
|
||
The yank level can also be specified with a prefix arg, or by
|
||
yanking after a headline marker like `****'.
|
||
|
||
When there is an active region (transient-mark-mode), promotion and
|
||
demotion work on all headlines in the region. To select a region of
|
||
headlines, it is best to place both point and mark at the beginning of a
|
||
line, mark at the beginning of the first headline, and point at the line
|
||
just after the last headline to change. Note that when the cursor is
|
||
inside a table (*note Tables::), the Meta-Cursor keys have different
|
||
functionality.

2.6 Archiving
|
||
=============
|
||
|
||
When a project represented by a (sub)tree is finished, you may want to
|
||
move the tree out of the way and to stop it from contributing to the
|
||
agenda. Org-mode knows two ways of archiving. You can mark a tree with
|
||
the ARCHIVE tag, or you can move an entire (sub)tree to a different
|
||
location.
|
||
|
||
* Menu:
|
||
|
||
* ARCHIVE tag:: Marking a tree as inactive
|
||
* Moving subtrees:: Moving a tree to an archive file

||

|
||
|
||
2.6.1 The ARCHIVE tag
|
||
---------------------
|
||
|
||
A headline that is marked with the ARCHIVE tag (*note Tags::) stays at
|
||
its location in the outline tree, but behaves in the following way:
|
||
- It does not open when you attempt to do so with a visibility
|
||
cycling command (*note Visibility cycling::). You can force
|
||
cycling archived subtrees with `C-<TAB>', or by setting the option
|
||
`org-cycle-open-archived-trees'. Also normal outline commands like
|
||
`show-all' will open archived subtrees.
|
||
|
||
- During sparse tree construction (*note Sparse trees::), matches in
|
||
archived subtrees are not exposed, unless you configure the option
|
||
`org-sparse-tree-open-archived-trees'.
|
||
|
||
- During agenda view construction (*note Agenda views::), the
|
||
content of archived trees is ignored unless you configure the
|
||
option `org-agenda-skip-archived-trees'.
|
||
|
||
- Archived trees are not exported (*note Exporting::), only the
|
||
headline is. Configure the details using the variable
|
||
`org-export-with-archived-trees'.
|
||
|
||
The following commands help managing the ARCHIVE tag:
|
||
|
||
`C-c C-x C-a'
|
||
Toggle the ARCHIVE tag for the current headline. When the tag is
|
||
set, the headline changes to a shadowish face, and the subtree
|
||
below it is hidden.
|
||
|
||
`C-u C-c C-x C-a'
|
||
Check if any direct children of the current headline should be
|
||
archived. To do this, each subtree is checked for open TODO
|
||
entries. If none are found, the command offers to set the ARCHIVE
|
||
tag for the child. If the cursor is _not_ on a headline when this
|
||
command is invoked, the level 1 trees will be checked.
|
||
|
||
`C-TAB'
|
||
Cycle a tree even if it is tagged with ARCHIVE.
|
||
|
||

||

||
|
||
2.6.2 Moving subtrees
|
||
---------------------
|
||
|
||
Once an entire project is finished, you may want to move it to a
|
||
different location, either in the current file, or even in a different
|
||
file, the archive file.
|
||
|
||
`C-c $'
|
||
Archive the subtree starting at the cursor position to the location
|
||
given by `org-archive-location'.
|
||
|
||
`C-u C-c $'
|
||
Check if any direct children of the current headline could be
|
||
moved to the archive. To do this, each subtree is checked for
|
||
open TODO entries. If none are found, the command offers to move
|
||
it to the archive location. If the cursor is _not_ on a headline
|
||
when this command is invoked, the level 1 trees will be checked.
|
||
|
||
The default archive location is a file in the same directory as the
|
||
current file, with the name derived by appending `_archive' to the
|
||
current file name. For information and examples on how to change this,
|
||
see the documentation string of the variable `org-archive-location'.

|
||
2.7 Sparse trees
|
||
================
|
||
|
||
An important feature of Org-mode is the ability to construct _sparse
|
||
trees_ for selected information in an outline tree. A sparse tree
|
||
means that the entire document is folded as much as possible, but the
|
||
selected information is made visible along with the headline structure
|
||
above it(1). Just try it out and you will see immediately how it works.
|
||
|
||
Org-mode contains several commands creating such trees. The most
|
||
basic one is `org-occur':
|
||
|
||
`C-c /'
|
||
Occur. Prompts for a regexp and shows a sparse tree with all
|
||
matches. If the match is in a headline, the headline is made
|
||
visible. If the match is in the body of an entry, headline and
|
||
body are made visible. In order to provide minimal context, also
|
||
the full hierarchy of headlines above the match is shown, as well
|
||
as the headline following the match. Each match is also
|
||
highlighted; the highlights disappear when the bufer is changes an
|
||
editing command, or by pressing `C-c C-c'. When called with a
|
||
`C-u' prefix argument, previous highlights are kept, so several
|
||
calls to this command can be stacked.
|
||
For frequently used sparse trees of specific search strings, you can
|
||
use the variable `org-agenda-custom-commands' to define fast keyboard
|
||
access to specific sparse trees. These commands will then be
|
||
accessible through the agenda dispatcher (*note Agenda dispatcher::).
|
||
For example:
|
||
|
||
(setq org-agenda-custom-commands
|
||
'(("f" occur-tree "FIXME")))
|
||
|
||
will define the key `C-c a f' as a shortcut for creating a sparse tree
|
||
matching the string `FIXME'.
|
||
|
||
Other commands use sparse trees as well. For example `C-c C-v'
|
||
creates a sparse TODO tree (*note TODO basics::).
|
||
|
||
To print a sparse tree, you can use the Emacs command
|
||
`ps-print-buffer-with-faces' which does not print invisible parts of
|
||
the document (2). Or you can use the command `C-c C-e v' to export
|
||
only the visible part of the document and print the resulting file.
|
||
|
||

|
||
|
||
(1) See also the variables `org-show-hierarchy-above' and
|
||
`org-show-following-heading'.
|
||
|
||
(2) This does not work under XEmacs, because XEmacs uses selective
|
||
display for outlining, not text properties.

|
||
2.8 Plain lists
|
||
===============
|
||
|
||
Within an entry of the outline tree, hand-formatted lists can provide
|
||
additional structure. They also provide a way to create lists of
|
||
checkboxes (*note Checkboxes::). Org-mode supports editing such lists,
|
||
and the HTML exporter (*note Exporting::) does parse and format them.
|
||
|
||
Org-mode knows ordered and unordered lists. Unordered list items
|
||
start with `-', `+', or `*'(1) as bullets. Ordered list items start
|
||
with `1.' or `1)'. Items belonging to the same list must have the same
|
||
indentation on the first line. In particular, if an ordered list
|
||
reaches number `10.', then the 2-digit numbers must be written
|
||
left-aligned with the other numbers in the list. Indentation also
|
||
determines the end of a list item. It ends before the next line that
|
||
is indented like the bullet/number, or less. For example:
|
||
|
||
** Lord of the Rings
|
||
My favorite scenes are (in this order)
|
||
1. The attack of the Rohirrim
|
||
2. Eowyns fight with the witch king
|
||
+ this was already my favorite scene in the book
|
||
+ I really like Miranda Otto.
|
||
3. Peter Jackson being shot by Legolas
|
||
- on DVD only
|
||
He makes a really funny face when it happens.
|
||
But in the end, not individual scenes matter but the film as a whole.
|
||
|
||
Org-mode supports these lists by tuning filling and wrapping
|
||
commands to deal with them correctly(2).
|
||
|
||
The following commands act on items when the cursor is in the first
|
||
line of an item (the line with the bullet or number).
|
||
|
||
`<TAB>'
|
||
Items can be folded just like headline levels if you set the
|
||
variable `org-cycle-include-plain-lists'. The level of an item is
|
||
then given by the indentation of the bullet/number. Items are
|
||
always subordinate to real headlines, however; the hierarchies
|
||
remain completely separated.
|
||
|
||
`M-<RET>'
|
||
Insert new item at current level. With prefix arg, force a new
|
||
heading (*note Structure editing::). If this command is used in
|
||
the middle of a line, the line is _split_ and the rest of the line
|
||
becomes the new item. If this command is executed in the
|
||
_whitespace before a bullet or number_, the new item is created
|
||
_before_ the current item. If the command is executed in the
|
||
white space before the text that is part of an item but does not
|
||
contain the bullet, a bullet is added to the current line.
|
||
|
||
`M-S-<RET>'
|
||
Insert a new item with a checkbox (*note Checkboxes::).
|
||
|
||
`S-<up>'
|
||
`S-<down>'
|
||
Jump to the previous/next item in the current list.
|
||
|
||
`M-S-<up>'
|
||
`M-S-<down>'
|
||
Move the item including subitems up/down (swap with previous/next
|
||
item of same indentation). If the list is ordered, renumbering is
|
||
automatic.
|
||
|
||
`M-S-<left>'
|
||
`M-S-<right>'
|
||
Decrease/increase the indentation of the item, including subitems.
|
||
Initially, the item tree is selected based on current indentation.
|
||
When these commands are executed several times in direct
|
||
succession, the initially selected region is used, even if the new
|
||
indentation would imply a different hierarchy. To use the new
|
||
hierarchy, break the command chain with a cursor motion or so.
|
||
|
||
`C-c C-c'
|
||
If there is a checkbox (*note Checkboxes::) in the item line,
|
||
toggle the state of the checkbox. Otherwise, if this is an
|
||
ordered list, renumber the ordered list at the cursor.
|
||
|
||
---------- Footnotes ----------
|
||
|
||
(1) When using `*' as a bullet, lines must be indented or they will
|
||
be seen as top-level headlines. Also, when you are hiding leading
|
||
stars to get a clean outline view, plain list items starting with a
|
||
star are visually indistinguishable from true headlines. In short:
|
||
even though `*' is supported, it may be better not to use it for plain
|
||
list items
|
||
|
||
(2) Org-mode only changes the filling settings for Emacs. For
|
||
XEmacs, you should use Kyle E. Jones' `filladapt.el'. To turn is on,
|
||
put into `.emacs':

||

3.1 The built-in table editor
|
||
=============================
|
||
|
||
Org-mode makes it easy to format tables in plain ASCII. Any line with
|
||
`|' as the first non-white character is considered part of a table.
|
||
`|' is also the column separator. A table might look like this:
|
||
|
||
| Name | Phone | Age |
|
||
|-------+-------+-----|
|
||
| Peter | 1234 | 17 |
|
||
| Anna | 4321 | 25 |
|
||
|
||
A table is re-aligned automatically each time you press <TAB> or
|
||
<RET> or `C-c C-c' inside the table. <TAB> also moves to the next
|
||
field (<RET> to the next row) and creates new table rows at the end of
|
||
the table or before horizontal lines. The indentation of the table is
|
||
set by the first line. Any line starting with `|-' is considered as a
|
||
horizontal separator line and will be expanded on the next re-align to
|
||
span the whole table width. So, to create the above table, you would
|
||
only type
|
||
|
||
|Name|Phone|Age|
|
||
|-
|
||
|
||
and then press <TAB> to align the table and start filling in fields.
|
||
|
||
When typing text into a field, Org-mode treats <DEL>, <Backspace>,
|
||
and all character keys in a special way, so that inserting and deleting
|
||
avoids shifting other fields. Also, when typing _immediately after the
|
||
cursor was moved into a new field with `<TAB>', `S-<TAB>' or `<RET>'_,
|
||
the field is automatically made blank. If this behavior is too
|
||
unpredictable for you, configure the variables
|
||
`org-enable-table-editor' and `org-table-auto-blank-field'.
|
||
|
||
Creation and conversion
|
||
.......................
|
||
|
||
`C-c |'
|
||
Convert the active region to table. If every line contains at
|
||
least one TAB character, the function assumes that the material is
|
||
tab separated. If not, lines are split at whitespace into fields.
|
||
You can use a prefix argument to indicate the minimum number of
|
||
consecutive spaces required to identify a field separator
|
||
(default: just one).
|
||
If there is no active region, this command creates an empty
|
||
Org-mode table. But it's easier just to start typing, like
|
||
`|Name|Phone|Age <RET> |- <TAB>'.
|
||
|
||
Re-aligning and field motion
|
||
............................
|
||
|
||
`C-c C-c'
|
||
Re-align the table without moving the cursor.
|
||
|
||
`<TAB>'
|
||
Re-align the table, move to the next field. Creates a new row if
|
||
necessary.
|
||
|
||
`S-<TAB>'
|
||
Re-align, move to previous field.
|
||
|
||
`<RET>'
|
||
Re-align the table and move down to next row. Creates a new row if
|
||
necessary. At the beginning or end of a line, <RET> still does
|
||
NEWLINE, so it can be used to split a table.
|
||
|
||
Column and row editing
|
||
......................
|
||
|
||
`M-<left>'
|
||
`M-<right>'
|
||
Move the current column left/right.
|
||
|
||
`M-S-<left>'
|
||
Kill the current column.
|
||
|
||
`M-S-<right>'
|
||
Insert a new column to the left of the cursor position.
|
||
|
||
`M-<up>'
|
||
`M-<down>'
|
||
Move the current row up/down.
|
||
|
||
`M-S-<up>'
|
||
Kill the current row or horizontal line.
|
||
|
||
`M-S-<down>'
|
||
Insert a new row above (with arg: below) the current row.
|
||
|
||
`C-c -'
|
||
Insert a horizontal line below current row. With prefix arg, the
|
||
line is created above the current line.
|
||
|
||
`C-c ^'
|
||
Sort the table lines in the region. Point and mark must be in the
|
||
first and last line to be included, and must be in the column that
|
||
should be used for sorting. The command prompts for numerical
|
||
versus alphanumerical sorting.
|
||
|
||
Regions
|
||
.......
|
||
|
||
`C-c C-x M-w'
|
||
Copy a rectangular region from a table to a special clipboard.
|
||
Point and mark determine edge fields of the rectangle. The
|
||
process ignores horizontal separator lines.
|
||
|
||
`C-c C-x C-w'
|
||
Copy a rectangular region from a table to a special clipboard, and
|
||
blank all fields in the rectangle. So this is the "cut" operation.
|
||
|
||
`C-c C-x C-y'
|
||
Paste a rectangular region into a table. The upper right corner
|
||
ends up in the current field. All involved fields will be
|
||
overwritten. If the rectangle does not fit into the present table,
|
||
the table is enlarged as needed. The process ignores horizontal
|
||
separator lines.
|
||
|
||
`C-c C-q'
|
||
Wrap several fields in a column like a paragraph. If there is an
|
||
active region, and both point and mark are in the same column, the
|
||
text in the column is wrapped to minimum width for the given
|
||
number of lines. A prefix ARG may be used to change the number of
|
||
desired lines. If there is no region, the current field is split
|
||
at the cursor position and the text fragment to the right of the
|
||
cursor is prepended to the field one line down. If there is no
|
||
region, but you specify a prefix ARG, the current field is made
|
||
blank, and the content is appended to the field above.
|
||
|
||
Calculations
|
||
............
|
||
|
||
`C-c ='
|
||
Install a new formula for the current column and replace current
|
||
field with the result of the formula.
|
||
|
||
`C-u C-c ='
|
||
Install a new formula for the current field, which must be a named
|
||
field. Evaluate the formula and replace the field content with the
|
||
result.
|
||
|
||
`C-c ''
|
||
Edit all formulas associated with the current table in a separate
|
||
buffer.
|
||
|
||
`C-c *'
|
||
Recalculate the current row by applying the stored formulas from
|
||
left to right. When called with a `C-u' prefix, recalculate the
|
||
entire table, starting with the first non-header line (i.e. below
|
||
the first horizontal separator line). For details, see *Note
|
||
Table calculations::.
|
||
|
||
`C-#'
|
||
Rotate the calculation mark in first column through the states `',
|
||
`#', `*', `!', `$'. For the meaning of these marks see *Note
|
||
Advanced features::. When there is an active region, change all
|
||
marks in the region.
|
||
|
||
`C-c ?'
|
||
Which table column is the cursor in? Displays number >0 in echo
|
||
area.
|
||
|
||
`C-c +'
|
||
Sum the numbers in the current column, or in the rectangle defined
|
||
by the active region. The result is shown in the echo area and can
|
||
be inserted with `C-y'.
|
||
|
||
`S-<RET>'
|
||
When current field is empty, copy from first non-empty field above.
|
||
When not empty, copy current field down to next row and move cursor
|
||
along with it. Depending on the variable
|
||
`org-table-copy-increment', integer field values will be
|
||
incremented during copy. This key is also used by CUA-mode (*note
|
||
Cooperation::).
|
||
|
||
Miscellaneous
|
||
.............
|
||
|
||
`C-c `'
|
||
Edit the current field in a separate window. This is useful for
|
||
fields that are not fully visible (*note Narrow columns::). When
|
||
called with a `C-u' prefix, just make the full field visible, so
|
||
that it can be edited in place.
|
||
|
||
`C-c <TAB>'
|
||
This is an alias for `C-u C-c `' to make the current field fully
|
||
visible.
|
||
|
||
`M-x org-table-import'
|
||
Import a file as a table. The table should be TAB- or whitespace
|
||
separated. Useful, for example, to import an Excel table or data
|
||
from a database, because these programs generally can write
|
||
TAB-separated text files. This command works by inserting the
|
||
file into the buffer and then converting the region to a table.
|
||
Any prefix argument is passed on to the converter, which uses it
|
||
to determine the separator.
|
||
|
||
`M-x org-table-export'
|
||
Export the table as a TAB-separated file. Useful for data
|
||
exchange with, for example, Excel or database programs.
|
||
|
||
|
||
If you don't like the automatic table editor because it gets in your
|
||
way on lines which you would like to start with `|', you can turn it
|
||
off with
|
||
|
||
(setq org-enable-table-editor nil)
|
||
|
||
Then the only table command that still works is `C-c C-c' to do a
|
||
manual re-align.

3.2 Narrow columns
|
||
==================
|
||
|
||
The width of columns is automatically determined by the table editor.
|
||
Sometimes a single field or a few fields need to carry more text,
|
||
leading to inconveniently wide columns. To limit(1) the width of a
|
||
column, one field anywhere in the column may contain just the string
|
||
`<N>' where `N' is an integer specifying the width of the column in
|
||
characters. The next re-align will then set the width of this column
|
||
to no more than this value.
|
||
|
||
|---+------------------------------| |---+--------|
|
||
| | | | | <6> |
|
||
| 1 | one | | 1 | one |
|
||
| 2 | two | ----\ | 2 | two |
|
||
| 3 | This is a long chunk of text | ----/ | 3 | This=> |
|
||
| 4 | four | | 4 | four |
|
||
|---+------------------------------| |---+--------|
|
||
|
||
Fields that are wider become clipped and end in the string `=>'. Note
|
||
that the full text is still in the buffer, it is only invisible. To
|
||
see the full text, hold the mouse over the field - a tooltip window
|
||
will show the full content. To edit such a field, use the command `C-c
|
||
`' (that is `C-c' followed by the backquote). This will open a new
|
||
window with the full field. Edit it and finish with `C-c C-c'.
|
||
|
||
When visiting a file containing a table with narrowed columns, the
|
||
necessary character hiding has not yet happened, and the table needs to
|
||
be aligned before it looks nice. Setting the option
|
||
`org-startup-align-all-tables' will realign all tables in a file upon
|
||
visiting, but also slow down startup. You can also set this option on
|
||
a per-file basis with:
|
||
|
||
#+STARTUP: align
|
||
#+STARTUP: noalign

3.3 Calculations in tables
|
||
==========================
|
||
|
||
The table editor makes use of the Emacs `calc' package to implement
|
||
spreadsheet-like capabilities. It can also evaluate Emacs Lisp forms to
|
||
derive fields from other fields. Org-mode has two levels of complexity
|
||
for table calculations. On the basic level, tables do only horizontal
|
||
computations, so a field can be computed from other fields _in the same
|
||
row_, and Org-mode assumes that there is only one formula for each
|
||
column. This is very efficient to work with and enough for many tasks.
|
||
On the complex level, columns and individual fields can be named for
|
||
easier referencing in formulas, individual named fields can have their
|
||
own formula associated with them, and recalculation can be automated.

|
||
|
||
3.3.1 Formula syntax
|
||
--------------------
|
||
|
||
A formula can be any algebraic expression understood by the Emacs
|
||
`calc' package. Note that `calc' has the slightly non-standard
|
||
convention that `/' has lower precedence than `*', so that `a/b*c' is
|
||
interpreted as `a/(b*c)'. Before evaluation by `calc-eval' (*note
|
||
calc-eval: (calc)Calling Calc from Your Programs.), variable
|
||
substitution takes place:
|
||
|
||
$ refers to the current field
|
||
$3 refers to the field in column 3 of the current row
|
||
$3..$7 a vector of the fields in columns 3-7 of current row
|
||
$P1..$P3 vector of column range, using column names
|
||
&2 second data field above the current, in same column
|
||
&5-2 vector from fifth to second field above current
|
||
&III-II vector of fields between 2nd and 3rd hline above
|
||
&III vector of fields between third hline above and current field
|
||
$name a named field, parameter or constant
|
||
|
||
The range vectors can be directly fed into the calc vector functions
|
||
like `vmean' and `vsum'.
|
||
|
||
`$name' is interpreted as the name of a column, parameter or
|
||
constant. Constants are defined globally through the variable
|
||
`org-table-formula-constants'. If you have the `constants.el' package,
|
||
it will also be used to resolve constants, including natural constants
|
||
like `$h' for Planck's constant, and units like `$km' for kilometers.
|
||
Column names and parameters can be specified in special table lines.
|
||
These are described below, see *Note Advanced features::.
|
||
|
||
A formula can contain an optional mode string after a semicolon.
|
||
This string consists of flags to influence calc's modes(1) during
|
||
execution, e.g. `p20' to switch the internal precision to 20 digits,
|
||
`n3', `s3', `e2' or `f4' to switch to normal, scientific, engineering,
|
||
or fixed display format, respectively, and `D', `R', `F', and `S' to
|
||
turn on degrees, radians, fraction and symbolic modes, respectively.
|
||
In addition, you may provide a `printf' format specifier to reformat
|
||
the final result. A few examples:
|
||
|
||
$1+$2 Sum of first and second field
|
||
$1+$2;%.2f Same, format result to two decimals
|
||
exp($2)+exp($1) Math functions can be used
|
||
$;%.1f Reformat current cell to 1 decimal
|
||
($3-32)*5/9 Degrees F -> C conversion
|
||
$c/$1/$cm Hz -> cm conversion, using `constants.el'
|
||
tan($1);Dp3s1 Compute in degrees, precision 3, display SCI 1
|
||
sin($1);Dp3%.1e Same, but use printf specifier for display
|
||
vmean($2..$7) Compute column range mean, using vector function
|
||
vsum(&III) Sum numbers from 3rd hline above, up to here
|
||
taylor($3,x=7,2) taylor series of $3, at x=7, second degree
|
||
|
||
---------- Footnotes ----------
|
||
|
||
(1) By default, Org-mode uses the standard calc modes (precision 12,
|
||
angular units degrees, fraction and symbolic modes off). The display
|
||
format, however, has been changed to `(float 5)' to keep tables compact.
|
||
The default settings can be configured using the variable
|
||
`org-calc-default-modes'.

3.3.2 Emacs Lisp forms as formulas
|
||
----------------------------------
|
||
|
||
It is also possible to write a formula in Emacs lisp; this can be useful
|
||
for string manipulation and control structures. If a formula starts
|
||
with a single quote followed by an opening parenthesis, then it is
|
||
evaluated as a lisp form. The evaluation should return either a string
|
||
or a number. Just as with `calc' formulas, you can provide a format
|
||
specifier after a semicolon. A few examples:
|
||
|
||
swap the first two characters of the content of column 1
|
||
'(concat (substring "$1" 1 2) (substring "$1" 0 1) (substring "$1" 2))
|
||
Add columns 1 and 2, equivalent to the calc's `$1+$2'
|
||
'(+ $1 $2)
|
||
|
||
|
||
File: org, Node: Column formulas, Next: Advanced features, Prev: Lisp formulas, Up: Table calculations
|
||
|
||
3.3.3 Column formulas
|
||
---------------------
|
||
|
||
To apply a formula to a field, type it directly into the field,
|
||
preceded by an equal sign, like `=$1+$2'. When you press <TAB> or
|
||
<RET> or `C-c C-c' with the cursor still in the field, the formula will
|
||
be stored as the formula for the current column, evaluated and the
|
||
current field replaced with the result. If the field contains only
|
||
`=', the previously stored formula for this column is used.
|
||
|
||
For each column, Org-mode will remember the most recently used
|
||
formula. The information is stored in a special line starting with
|
||
`#+TBLFM' directly below the table. When adding/deleting/moving
|
||
columns with the appropriate commands, the stored equations will be
|
||
modified accordingly. When a column used in a calculation is removed,
|
||
references to this column become invalid and will cause an error upon
|
||
applying the equation.
|
||
|
||
Instead of typing an equation into the field, you may also use the
|
||
command `C-c ='. It prompts for a formula (with default taken from the
|
||
`#+TBLFM:' line) and applies it to the current field. A numerical
|
||
prefix (e.g. `C-5 C-c =') will apply it to that many consecutive fields
|
||
in the current column.
|
||
|
||
To recompute all the fields in a line, use the command `C-c *'. It
|
||
re-applies all stored equations to the current row, from left to right.
|
||
With a `C-u' prefix, this will be done to every line in the table, so
|
||
use this command it you want to make sure the entire table is
|
||
up-to-date. `C-u C-c C-c' is another way to update the entire table.
|
||
Global updating does not touch the line(s) above the first horizontal
|
||
separator line, assuming that this is the table header.

3.3.4 Advanced features
|
||
-----------------------
|
||
|
||
If you want the recalculation of fields to happen automatically, or if
|
||
you want to be able to assign a formula to an individual field (instead
|
||
of an entire column) you need to reserve the first column of the table
|
||
for special marking characters. Here is an example of a table that
|
||
collects exam results of students and makes use of these features:
|
||
|
||
|---+---------+--------+--------+--------+-------+------|
|
||
| | Student | Prob 1 | Prob 2 | Prob 3 | Total | Note |
|
||
|---+---------+--------+--------+--------+-------+------|
|
||
| ! | | P1 | P2 | P3 | Tot | |
|
||
| # | Maximum | 10 | 15 | 25 | 50 | 10.0 |
|
||
| ^ | | m1 | m2 | m3 | mt | |
|
||
|---+---------+--------+--------+--------+-------+------|
|
||
| # | Peter | 10 | 8 | 23 | 41 | 8.2 |
|
||
| # | Sara | 6 | 14 | 19 | 39 | 7.8 |
|
||
| # | Sam | 2 | 4 | 3 | 9 | 1.8 |
|
||
|---+---------+--------+--------+--------+-------+------|
|
||
| | Average | | | | 29.7 | |
|
||
| ^ | | | | | at | |
|
||
| $ | max=50 | | | | | |
|
||
|---+---------+--------+--------+--------+-------+------|
|
||
#+TBLFM: $6=vsum($P1..$P3)::$7=10*$Tot/$max;%.1f::$at=vmean(&II);%.1f
|
||
|
||
Important: Please note that for these special tables, recalculating the
|
||
table with `C-u C-c *' will only affect rows that are marked `#' or
|
||
`*', and named fields. The column formulas are not applied in rows
|
||
with empty first field.
|
||
|
||
The marking characters have the following meaning:
|
||
`!'
|
||
The fields in this line define names for the columns, so that you
|
||
may refer to a column as `$Tot' instead of `$6'.
|
||
|
||
`^'
|
||
This row defines names for the fields _above_ the row. With such
|
||
a definition, any formula in the table may use `$m1' to refer to
|
||
the value `10'. Also, named fields can have their own formula
|
||
associated with them.
|
||
|
||
`_'
|
||
Similar to `^', but defines names for the fields in the row
|
||
_below_.
|
||
|
||
`$'
|
||
Fields in this row can define _parameters_ for formulas. For
|
||
example, if a field in a `$' row contains `max=50', then formulas
|
||
in this table can refer to the value 50 using `$max'. Parameters
|
||
work exactly like constants, only that they can be defined on a
|
||
per-table basis. Changing a parameter and then recalculating the
|
||
table can be useful.
|
||
|
||
`#'
|
||
Fields in this row are automatically recalculated when pressing
|
||
<TAB> or <RET> or `S-<TAB>' in this row. Also, this row is
|
||
selected for a global recalculation with `C-u C-c *'. Unmarked
|
||
lines will be left alone by this command.
|
||
|
||
`*'
|
||
Selects this line for global recalculation with `C-u C-c *', but
|
||
not for automatic recalculation. Use this when automatic
|
||
recalculation slows down editing too much.
|
||
|
||
`'
|
||
Unmarked lines are exempt from recalculation with `C-u C-c *'.
|
||
All lines that should be recalculated should be marked with `#' or
|
||
`*'.

||
3.3.5 Named-field formulas
|
||
--------------------------
|
||
|
||
A named field can have its own formula associated with it. In the
|
||
example above, this is used for the `at' field that contains the
|
||
average result of the students. To enter a formula for a named field,
|
||
just type it into the buffer, preceded by `:='. Or use `C-u C-c ='.
|
||
This equation will be stored below the table like `$name=...'. Any
|
||
recalculation in the table (even if only requested for the current
|
||
line) will also update all named field formulas.
|
||
|
||
|
||
File: org, Node: Editing/debugging formulas, Next: Appetizer, Prev: Named-field formulas, Up: Table calculations
|
||
|
||
3.3.6 Editing and debugging formulas
|
||
------------------------------------
|
||
|
||
To edit a column or field formula, use the commands `C-c =' and `C-u
|
||
C-c =', respectively. The currently active expression is then
|
||
presented as default in the minibuffer, where it may be edited.
|
||
|
||
Note that making a table field blank does not remove the formula
|
||
associated with the field - during the next recalculation the field
|
||
will be filled again. To remove a formula from a field, you have to
|
||
give an empty reply when prompted for the formula, or to edit the
|
||
`#+TBLFM' line.
|
||
|
||
You may edit the `#+TBLFM' directly and re-apply the changed
|
||
equations with `C-c C-c' in that line, or with the normal recalculation
|
||
commands in the table.
|
||
|
||
In particular for large tables with many formulas, it is convenient
|
||
to use the command `C-c '' to edit the formulas of the current table in
|
||
a separate buffer. That buffer will show the formulas one per line,
|
||
and you are free to edit, add and remove formulas. Press `C-c ?' on a
|
||
`$...' expression to get information about its interpretation.
|
||
Exiting the buffer with `C-c C-c' only stores the modified formulas
|
||
below the table. Exiting with `C-u C-c C-c' also applies them to the
|
||
entire table. `C-c C-q' exits without installing the changes.
|
||
|
||
When the evaluation of a formula leads to an error, the field content
|
||
becomes the string `#ERROR'. If you would like see what is going on
|
||
during variable substitution and calculation in order to find a bug,
|
||
turn on formula debugging in the menu and repeat the calculation, for
|
||
example by pressing `C-c = <RET>' in a field. Detailed information
|
||
will be displayed.

3.4 The Orgtbl minor mode
|
||
=========================
|
||
|
||
If you like the intuitive way the Org-mode table editor works, you
|
||
might also want to use it in other modes like text-mode or mail-mode.
|
||
The minor mode Orgtbl-mode makes this possible. You can always toggle
|
||
the mode with `M-x orgtbl-mode'. To turn it on by default, for example
|
||
in mail mode, use
|
||
|
||
(add-hook 'mail-mode-hook 'turn-on-orgtbl)

3.5 The `table.el' package
|
||
==========================
|
||
|
||
Complex ASCII tables with automatic line wrapping, column- and
|
||
row-spanning, and alignment can be created using the Emacs table
|
||
package by Takaaki Ota (`http://sourceforge.net/projects/table', and
|
||
also part of Emacs 22). When <TAB> or `C-c C-c' is pressed in such a
|
||
table, Org-mode will call `table-recognize-table' and move the cursor
|
||
into the table. Inside a table, the keymap of Org-mode is inactive.
|
||
In order to execute Org-mode-related commands, leave the table.
|
||
|
||
`C-c C-c'
|
||
Recognize `table.el' table. Works when the cursor is in a
|
||
table.el table.
|
||
|
||
`C-c ~'
|
||
Insert a table.el table. If there is already a table at point,
|
||
this command converts it between the table.el format and the
|
||
Org-mode format. See the documentation string of the command
|
||
`org-convert-table' for the restrictions under which this is
|
||
possible.

4.1 Link format
|
||
===============
|
||
|
||
Org-mode will recognize plain URL-like links and activate them as
|
||
clickable links. The general link format, however, looks like this:
|
||
|
||
[[link][description]] or alternatively [[link]]
|
||
|
||
Once a link in the buffer is complete (all brackets present),
|
||
Org-mode will change the display so that `description' is displayed
|
||
instead of `[[link][description]]' and `link' is displayed instead of
|
||
`[[link]]'. Links will be highlighted in the face `org-link', which by
|
||
default is an underlined face. You can directly edit the visible part
|
||
of a link. Note that this can be either the `link' part (if there is
|
||
no description) or the `description' part. To edit also the invisible
|
||
`link' part, use `C-c C-l' with the cursor on the link.
|
||
|
||
If you place the cursor at the beginning or just behind the end of
|
||
the displayed text and press <BACKSPACE>, you will remove the
|
||
(invisible) bracket at that location. This makes the link incomplete
|
||
and the internals are again displayed as plain text. Inserting the
|
||
missing bracket hides the link internals again. To show the internal
|
||
structure of all links, use the menu entry `Org->Hyperlinks->Literal
|
||
links'.

|
||
If the link does not look like a URL, it is considered to be internal in
|
||
the current file. Links such as `[[My Target]]' or `[[My Target][Find
|
||
my target]]' lead to a text search in the current file. The link can
|
||
be followed with `C-c C-o' when the cursor is on the link, or with a
|
||
mouse click (*note Handling links::). The preferred match for such a
|
||
link is a dedicated target: the same string in double angular brackets.
|
||
Targets may be located anywhere; often it is convenient to put them
|
||
into a comment line. For example
|
||
|
||
# <<My Target>>
|
||
|
||
In HTML export (*note HTML export::), such targets will become named
|
||
anchors for direct access through `http' links(1).
|
||
|
||
If no dedicated target exists, Org-mode will search for the words in
|
||
the link. In the above example the search would be for `my target'.
|
||
Links starting with a star like `*My Target' restrict the search to
|
||
headlines. When searching, Org-mode will first try an exact match, but
|
||
then move on to more and more lenient searches. For example, the link
|
||
`[[*My Targets]]' will find any of the following:
|
||
|
||
** My targets
|
||
** TODO my targets are bright
|
||
** my 20 targets are
|
||
|
||
To insert a link targeting a headline, in-buffer completion can be
|
||
used. Just type a star followed by a few optional letters into the
|
||
buffer and press `M-<TAB>'. All headlines in the current buffer will be
|
||
offered as completions. *Note Handling links::, for more commands
|
||
creating links.
|
||
|
||
Following a link pushes a mark onto Org-mode's own mark ring. You
|
||
can return to the previous position with `C-c &'. Using this command
|
||
several times in direct succession goes back to positions recorded
|
||
earlier.

4.2.1 Radio targets
|
||
-------------------
|
||
|
||
You can configure Org-mode to link any occurrences of certain target
|
||
names in normal text. So without explicitly creating a link, the text
|
||
connects to the target radioing its position. Radio targets are
|
||
enclosed by triple angular brackets. For example, a target `<<<My
|
||
Target>>>' causes each occurrence of `my target' in normal text to
|
||
become activated as a link. The Org-mode file is scanned automatically
|
||
for radio targets only when the file is first loaded into Emacs. To
|
||
update the target list during editing, press `C-c C-c' with the cursor
|
||
on or at a target.

4.2.2 CamelCase words as links
|
||
------------------------------
|
||
|
||
Org-mode also supports CamelCase words as links. This feature is not
|
||
turned on by default because of the inconsistencies this system suffers
|
||
from. It is also possible that this feature will disappear entirely in
|
||
a future version of Org-mode. To activate CamelCase words as links, you
|
||
need to customize the option `org-activate-links'. A CamelCase word
|
||
then leads to a text search such that `CamelCaseLink' is equivalent to
|
||
`[[camel case link]]'.

4.3 External links
|
||
==================
|
||
|
||
Org-mode supports links to files, websites, Usenet and email messages,
|
||
and BBDB database entries. External links are URL-like locators. They
|
||
start with a short identifying string followed by a colon. There can be
|
||
no space after the colon. The following list shows examples for each
|
||
link type.

A link should be enclosed in double brackets and may contain a

descriptive text to be displayed instead of the url (*note Link
|
||
format::), for example:
|
||
|
||
[[http://www.gnu.org/software/emacs/][GNU Emacs]]
|
||
|
||
Org-mode also finds external links in the normal text and activates
|
||
them as links. If spaces must be part of the link (for example in
|
||
`bbdb:Richard Stallman'), or you need to remove ambiguities about the
|
||
end of the link, enclose them in angular brackets.

4.4 Handling links
|
||
==================
|
||
|
||
Org-mode provides methods to create a link in the correct syntax, to
|
||
insert it into an org-mode file, and to follow the link.
|
||
|
||
`C-c l'
|
||
Store a link to the current location. This is a _global_ command
|
||
which can be used in any buffer to create a link. The link will be
|
||
stored for later insertion into an Org-mode buffer (see below).
|
||
For Org-mode files, if there is a `<<target>>' at the cursor, the
|
||
link points to the target. Otherwise it points to the current
|
||
headline. For VM, RMAIL, WANDERLUST, MH-E, GNUS and BBDB buffers,
|
||
the link will indicate the current article/entry. For W3 and W3M
|
||
buffers, the link goes to the current URL. For any other files,
|
||
the link will point to the file, with a search string (*note
|
||
Search options::) pointing to the contents of the current line.
|
||
If there is an active region, the selected words will form the
|
||
basis of the search string. If the automatically created link is
|
||
not working correctly or accurately enough, you can write custom
|
||
functions to select the search string and to do the search for
|
||
particular file types - see *Note Custom searches::. The key
|
||
binding `C-c l' is only a suggestion - see *Note Installation::.
|
||
|
||
`C-c C-l'
|
||
Insert a link. This prompts for a link to be inserted into the
|
||
buffer. You can just type a link, using text for an internal
|
||
link, or one of the link type prefixes mentioned in the examples
|
||
above. Through completion, all links stored during the current
|
||
session can be accessed(1). The link will be inserted into the
|
||
buffer, along with a descriptive text. Note that you don't have
|
||
to use this command to insert a link. Links in Org-mode are plain
|
||
text, and you can type or paste them straight into the buffer. By
|
||
using this command, the links are automatically enclosed in double
|
||
brackets, and you will be asked for the optional descriptive text.
|
||
If the link is a `file:' link and the linked file is located in
|
||
the same directory as the current file or a subdirectory of it, the
|
||
path of the file will be inserted relative to the current
|
||
directory.
|
||
|
||
`C-u C-c C-l'
|
||
When `C-c C-l' is called with a `C-u' prefix argument, a link to a
|
||
file will be inserted and you may use file name completion to
|
||
select the name of the file. The path to the file is inserted
|
||
relative to the directory of the current org file, if the linked
|
||
file is in the current directory or in a subdirectory of it, or if
|
||
the path is written relative to the current directory using `../'.
|
||
Otherwise an absolute path is used, if possible with `~/' for
|
||
your home directory. You can force an absolute path with two
|
||
`C-u' prefixes.
|
||
|
||
`C-c C-l with cursor on existing link'
|
||
When the cursor is on an existing link, `C-c C-l' allows you to
|
||
edit the link and description parts of the link.
|
||
|
||
`C-c C-o'
|
||
Open link at point. This will launch a web browser for URLs (using
|
||
`browse-url-at-point'), run vm/mh-e/wanderlust/rmail/gnus/bbdb for
|
||
the corresponding links, and execute the command in a shell link.
|
||
When the cursor is on an internal link, this commands runs the
|
||
corresponding search. When the cursor is on a TAG list in a
|
||
headline, it creates the corresponding TAGS view. If the cursor
|
||
is on a time stamp, it compiles the agenda for that date.
|
||
Furthermore, it will visit text and remote files in `file:' links
|
||
with Emacs and select a suitable application for local non-text
|
||
files. Classification of files is based on file extension only.
|
||
See option `org-file-apps'. If you want to override the default
|
||
application and visit the file with Emacs, use a `C-u' prefix.
|
||
|
||
`mouse-2'
|
||
`mouse-1'
|
||
On links, `mouse-2' will open the link just as `C-c C-o' would.
|
||
Under Emacs 22, also `mouse-1' will follow a link.
|
||
|
||
`mouse-3'
|
||
Like `mouse-2', but force file links to be opened with Emacs, and
|
||
internal links to be displayed in another window(2).
|
||
|
||
`C-c %'
|
||
Push the current position onto the mark ring, to be able to return
|
||
easily. Commands following an internal link do this automatically.
|
||
|
||
`C-c &'
|
||
Jump back to a recorded position. A position is recorded by the
|
||
commands following internal links, and by `C-c %'. Using this
|
||
command several times in direct succession moves through a ring of
|
||
previously recorded positions.
|
||
|
||
---------- Footnotes ----------
|
||
|
||
(1) After insertion of a stored link, the link will be removed from
|
||
the list of stored links. To keep it in the list later use, use a
|
||
triple `C-u' prefix to `C-c C-l', or configure the option
|
||
`org-keep-stored-link-after-insertion'.

||
4.5 Link abbreviatons
|
||
=====================
|
||
|
||
Long URLs can be cumbersome to type, and often many similar links are
|
||
needed in a document. For this you can use link abbreviations. An
|
||
abbreviated link looks like this
|
||
|
||
[[linkword::tag][description]]
|
||
|
||
where the tag is optional. Such abbreviations are resolved according to
|
||
the information in the variable `org-link-abbrev-alist' that relates
|
||
the linkwords to replacement text. Here is an example:
|
||
|
||
(setq org-link-abbrev-alist
|
||
'(("bugzilla" . "http://10.1.2.9/bugzilla/show_bug.cgi?id=")
|
||
("google" . "http://www.google.com/search?q=")
|
||
("ads" . "http://adsabs.harvard.edu/cgi-bin/
|
||
nph-abs_connect?author=%s&db_key=AST")))
|
||
|
||
If the replacement text contains the string `%s', it will be
|
||
replaced with the tag. Otherwise the tag will be appended to the string
|
||
in order to create the link. You may also specify a function that will
|
||
be called with the tag as the only argument to create the link.
|
||
|
||
With the above setting, you could link to a specific bug with
|
||
`[[bugzilla::129]]', search the web for OrgMode with
|
||
`[[google::OrgMode]]' and find out what the Org-mode author is doing
|
||
besides Emacs hacking with `[[ads::Dominik,C]]'.
|
||
|
||
If you need special abbreviations just for a single Org-mode buffer,
|
||
you can define them in the file with
|
||
|
||
#+LINK: bugzilla http://10.1.2.9/bugzilla/show_bug.cgi?id=
|
||
#+LINK: google http://www.google.com/search?q=%s
|
||
|
||
In-buffer completion *note Completion:: can be used after `[' to
|
||
complete link abbreviations.

|
||
|
||
4.6 Search options in file links
|
||
================================
|
||
|
||
File links can contain additional information to make Emacs jump to a
|
||
particular location in the file when following a link. This can be a
|
||
line number or a search option after a double(1) colon. For example,
|
||
when the command `C-c l' creates a link (*note Handling links::) to a
|
||
file, it encodes the words in the current line as a search string that
|
||
can be used to find this line back later when following the link with
|
||
`C-c C-o'.
|
||
|
||
Here is the syntax of the different ways to attach a search to a file
|
||
link, together with an explanation:
|
||
|
||
[[file:~/code/main.c::255]]
|
||
[[file:~/xx.org::My Target]]
|
||
[[file:~/xx.org::*My Target]]
|
||
[[file:~/xx.org::/regexp/]]
|
||
|
||
`255'
|
||
Jump to line 255.
|
||
|
||
`My Target'
|
||
Search for a link target `<<My Target>>', or do a text search for
|
||
`my target', similar to the search in internal links, see *Note
|
||
Internal links::. In HTML export (*note HTML export::), such a
|
||
file link will become an HTML reference to the corresponding named
|
||
anchor in the linked file.
|
||
|
||
`*My Target'
|
||
In an Org-mode file, restrict search to headlines.
|
||
|
||
`/regexp/'
|
||
Do a regular expression search for `regexp'. This uses the Emacs
|
||
command `occur' to list all matches in a separate window. If the
|
||
target file is in Org-mode, `org-occur' is used to create a sparse
|
||
tree with the matches.
|
||
|
||
As a degenerate case, a file link with an empty file name can be used
|
||
to search the current file. For example, `<file:::find me>' does a
|
||
search for `find me' in the current file, just as `[[find me]]' would.
|
||
|
||

|
||

||

|
||
single colon.

||
4.7 Custom Searches
|
||
===================
|
||
|
||
The default mechanism for creating search strings and for doing the
|
||
actual search related to a file link may not work correctly in all
|
||
cases. For example, BibTeX database files have many entries like
|
||
`year="1993"' which would not result in good search strings, because
|
||
the only unique identification for a BibTeX entry is the citation key.
|
||
|
||
If you come across such a problem, you can write custom functions to
|
||
set the right search string for a particular file type, and to do the
|
||
search for the string in the file. Using `add-hook', these functions
|
||
need to be added to the hook variables
|
||
`org-create-file-search-functions' and
|
||
`org-execute-file-search-functions'. See the docstring for these
|
||
variables for more information. Org-mode actually uses this mechanism
|
||
for BibTeX database files, and you can use the corresponding code as an
|
||
implementation example. Search for `BibTeX links' in the source file.

||
|
||

||

|

|
||
4.8 Remember
|
||
============
|
||
|
||
Another way to create org entries with links to other files is through
|
||
the _Remember_ package by John Wiegley. _Remember_ lets you store
|
||
quick notes with little interruption of your work flow. See
|
||
`http://www.emacswiki.org/cgi-bin/wiki/RememberMode' for more
|
||
information. The notes produced by _Remember_ can be stored in
|
||
different ways, and Org-mode files are a good target. Org-mode allows
|
||
you to file away notes either to a default file, or directly to the
|
||
correct location in your Org-mode outline tree. The following
|
||
customization will tell _Remember_ to use org files as target, and to
|
||
create annotations compatible with Org-mode links.
|
||
|
||
(setq org-directory "~/path/to/my/orgfiles/")
|
||
(setq org-default-notes-file "~/.notes")
|
||
(setq remember-annotation-functions '(org-remember-annotation))
|
||
(setq remember-handler-functions '(org-remember-handler))
|
||
(add-hook 'remember-mode-hook 'org-remember-apply-template)
|
||
|
||
In combination with Org-mode, you can use templates to generate
|
||
different types of remember notes. For example, if you would like to
|
||
use one template to create general TODO entries, and another one for
|
||
journal entries, you could use:
|
||
|
||
(setq org-remember-templates
|
||
'((?t "* TODO %?\n %i\n %a" "~/org/TODO.org")
|
||
(?j "* %U %?\n\n %i\n %a" "~/org/JOURNAL.org")))
|
||
|
||
In these entries, the character specifies how to select the template,
|
||
the first string specifies the template, and the (optional) second
|
||
string specifies a default file (overruling `org-default-notes-file')
|
||
as a target for this note.
|
||
|
||
When you call `M-x remember' to remember something, org will prompt
|
||
for a key to select the template and then prepare the buffer like
|
||
* TODO
|
||
<file:link to where you called remember>
|
||
|
||
or
|
||
|
||
* [2006-03-21 Tue 15:37]
|
||
|
||
<file:link to where you called remember>
|
||
|
||
See the variable `org-remember-templates' for more details.
|
||
|
||
When you are finished composing a note with remember, you have to
|
||
press `C-c C-c' to file the note away. The handler first prompts for a
|
||
target file - if you press <RET>, the value of `org-default-notes-file'
|
||
is used. Then the command offers the headings tree of the selected
|
||
file. You can either immediately press <RET> to get the note appended
|
||
to the file. Or you can use vertical cursor motion (<up> and <down>)
|
||
and visibility cycling (<TAB>) to find a better place. Pressing <RET>
|
||
or <left> or <right> leads to the following result.
|
||
|
||
Cursor Key Note gets inserted
|
||
position
|
||
buffer-start <RET> as level 2 heading at end of file
|
||
on headline <RET> as sublevel of the heading at cursor
|
||
<left> as same level, before current heading
|
||
<right> as same level, after current heading
|
||
not on <RET> at cursor position, level taken from context.
|
||
headline Or use prefix arg to specify level
|
||
manually.
|
||
|
||
So a fast way to store the note is to press `C-c C-c <RET> <RET>' to
|
||
append it to the default file. Even shorter would be `C-u C-c C-c',
|
||
which does the same without even showing the tree. But with little
|
||
extra effort, you can push it directly to the correct location.
|
||
|
||
Before inserting the text into a tree, the function ensures that the
|
||
text has a headline, i.e. a first line that starts with a `*'. If not,
|
||
a headline is constructed from the current date and some additional
|
||
data. If the variable `org-adapt-indentation' is non-nil, the entire
|
||
text is also indented so that it starts in the same column as the
|
||
headline (after the asterisks).

5 TODO items
|
||
************
|
||
|
||
Org-mode does not maintain TODO lists as a separate document. TODO
|
||
items are an integral part of the notes file, because TODO items
|
||
usually come up while taking notes! With Org-mode, you simply mark any
|
||
entry in a tree as being a TODO item. In this way, the information is
|
||
not duplicated, and the entire context from which the item emerged is
|
||
always present when you check.
|
||
|
||
Of course, this technique causes TODO items to be scattered
|
||
throughout your file. Org-mode provides methods to give you an
|
||
overview over all things you have to do.

5.1 Basic TODO functionality
|
||
============================
|
||
|
||
Any headline can become a TODO item by starting it with the word TODO,
|
||
for example:
|
||
|
||
*** TODO Write letter to Sam Fortune
|
||
|
||
The most important commands to work with TODO entries are:
|
||
|
||
`C-c C-t'
|
||
Rotate the TODO state of the current item between
|
||
|
||
,-> (unmarked) -> TODO -> DONE --.
|
||
'--------------------------------'
|
||
|
||
The same rotation can also be done "remotely" from the timeline and
|
||
agenda buffers with the `t' command key (*note Agenda commands::).
|
||
|
||
`S-<right>'
|
||
`S-<left>'
|
||
Select the following/preceding TODO state, similar to cycling.
|
||
Mostly useful if more than two TODO states are possible (*note
|
||
TODO extensions::).
|
||
|
||
`C-c C-v'
|
||
View TODO items in a _sparse tree_ (*note Sparse trees::). Folds
|
||
the entire buffer, but shows all TODO items and the headings
|
||
hierarchy above them. With prefix arg, show also the DONE
|
||
entries. With numerical prefix N, show the tree for the Nth
|
||
keyword in the variable `org-todo-keywords'.
|
||

5.2 Extended use of TODO keywords
|
||
=================================
|
||
|
||
The default implementation of TODO entries is just two states: TODO and
|
||
DONE. You can, however, use the TODO feature for more complicated
|
||
things by configuring the variables `org-todo-keywords' and
|
||
`org-todo-interpretation'. Using special setup, you can even use TODO
|
||
keywords in different ways in different org files.
|
||
|
||
Note that tags are another way to classify headlines in general and
|
||
TODO items in particular (*note Tags::).
|
||
|
||
* Menu:
|
||
|
||
* Workflow states:: From TODO to DONE in steps
|
||
* TODO types:: I do this, Fred the rest
|
||
* Per file keywords:: Different files, different requirements
|
||
|
||
|
||
File: org, Node: Workflow states, Next: TODO types, Prev: TODO extensions, Up: TODO extensions
|
||
|
||
5.2.1 TODO keywords as workflow states
|
||
--------------------------------------
|
||
|
||
You can use TODO keywords to indicate different states in the process
|
||
of working on an item, for example:
|
||
|
||
(setq org-todo-keywords '("TODO" "FEEDBACK" "VERIFY" "DONE")
|
||
org-todo-interpretation 'sequence)
|
||
|
||
Changing these variables only becomes effective in a new Emacs
|
||
session. With this setup, the command `C-c C-t' will cycle an entry
|
||
from TODO to FEEDBACK, then to VERIFY, and finally to DONE. You may
|
||
also use a prefix argument to quickly select a specific state. For
|
||
example `C-3 C-c C-t' will change the state immediately to VERIFY. If
|
||
you define many keywords, you can use in-buffer completion (see *Note
|
||
Completion::) to insert these words into the buffer.
|
||
|
||
|
||
File: org, Node: TODO types, Next: Per file keywords, Prev: Workflow states, Up: TODO extensions
|
||
|
||
5.2.2 TODO keywords as types
|
||
----------------------------
|
||
|
||
The second possibility is to use TODO keywords to indicate different
|
||
types of action items. For example, you might want to indicate that
|
||
items are for "work" or "home". If you are into David Allen's _Getting
|
||
Things DONE_, you might want to use todo types `NEXTACTION', `WAITING',
|
||
`MAYBE'. Or, when you work with several people on a single project,
|
||
you might want to assign action items directly to persons, by using
|
||
their names as TODO keywords. This would be set up like this:
|
||
|
||
(setq org-todo-keywords '("Fred" "Sara" "Lucy" "Mike" "DONE")
|
||
org-todo-interpretation 'type)
|
||
|
||
In this case, different keywords do not indicate a sequence, but
|
||
rather different types. So it is normally not useful to change from
|
||
one type to another. Therefore, in this case the behavior of the
|
||
command `C-c C-t' is changed slightly(1). When used several times in
|
||
succession, it will still cycle through all names. But when you return
|
||
to the item after some time and execute `C-c C-t' again, it will switch
|
||
from each name directly to DONE. Use prefix arguments or completion to
|
||
quickly select a specific name. You can also review the items of a
|
||
specific TODO type in a sparse tree by using a numeric prefix to `C-c
|
||
C-v'. For example, to see all things Lucy has to do, you would use
|
||
`C-3 C-c C-v'. To collect Lucy's items from all agenda files into a
|
||
single buffer, you would use the prefix arg as well when creating the
|
||
global todo list: `C-3 C-c t'.
|
||
|
||
---------- Footnotes ----------
|
||
|
||
(1) This is also true for the `t' command in the timeline and agenda
|
||
buffers.

|
||
|
||
5.2.3 Setting up TODO keywords for individual files
|
||
---------------------------------------------------
|
||
|
||
It can be very useful to use different aspects of the TODO mechanism in
|
||
different files, which is not possible with the global settings
|
||
described above. For file-local settings, you need to add special
|
||
lines to the file which set the keywords and interpretation for that
|
||
file only. For example, to set one of the two examples discussed
|
||
above, you need one of the following lines, starting in column zero
|
||
anywhere in the file:
|
||
|
||
#+SEQ_TODO: TODO FEEDBACK VERIFY DONE
|
||
#+TYP_TODO: Fred Sara Lucy Mike DONE
|
||
|
||
To make sure you are using the correct keyword, type `#+' into the
|
||
buffer and then use `M-<TAB>' completion.
|
||
|
||
Remember that the last keyword must always mean that the item is DONE
|
||
(although you may use a different word). Also note that in each file,
|
||
only one of the two aspects of TODO keywords can be used. After
|
||
changing one of these lines, use `C-c C-c' with the cursor still in the
|
||
line to make the changes known to Org-mode(1).
|
||
|
||
If you want to use very many keywords, for example when working with
|
||
a large group of people, you may split the names over several lines:
|
||
|
||
#+TYP_TODO: Fred Sara Lucy Mike
|
||
#+TYP_TODO: Luis George Jules Jessica
|
||
#+TYP_TODO: Kim Arnold Peter
|
||
#+TYP_TODO: DONE
|
||
|
||
---------- Footnotes ----------
|
||
|
||
(1) Org-mode parses these lines only when Org-mode is activated
|
||
after visiting a file. `C-c C-c' with the cursor in a line starting
|
||
with `#+' is simply restarting Org-mode for the current buffer.

|
||
5.3 Priorities
|
||
==============
|
||
|
||
If you use Org-mode extensively to organize your work, you may end up
|
||
with a number of TODO entries so large that you'd like to prioritize
|
||
them. This can be done by placing a _priority cookie_ into the
|
||
headline, like this
|
||
|
||
*** TODO [#A] Write letter to Sam Fortune
|
||
|
||
With its standard setup, Org-mode supports priorities `A', `B', and
|
||
`C'. `A' is the highest priority. An entry without a cookie is
|
||
treated as priority `B'. Priorities make a difference only in the
|
||
agenda (*note Weekly/Daily agenda::).
|
||
|
||
`C-c ,'
|
||
Set the priority of the current headline. The command prompts for
|
||
a priority character `A', `B' or `C'. When you press <SPC>
|
||
instead, the priority cookie is removed from the headline. The
|
||
priorities can also be changed "remotely" from the timeline and
|
||
agenda buffer with the `,' command (*note Agenda commands::).
|
||
|
||
`S-<up>'
|
||
`S-<down>'
|
||
Increase/decrease priority of current headline. Note that these
|
||
keys are also used to modify time stamps (*note Creating
|
||
timestamps::). Furthermore, these keys are also used by CUA-mode
|
||
(*note Conflicts::).

||
5.4 Breaking tasks down into subtasks
|
||
=====================================
|
||
|
||
It is often advisable to break down large tasks into smaller, managable
|
||
subtasks. You can do this by creating an outline tree below a TODO
|
||
item, with detailed subtasks on the tree(1). Another possibility is
|
||
the use of checkboxes to ideantify (a hierarchy of) a large number of
|
||
subtasks (*note Checkboxes::).
|
||
|
||
---------- Footnotes ----------
|
||
|
||
(1) To keep subtasks out of the global TODO list, see the
|
||
`org-agenda-todo-list-sublevels'.
|
||
|
||
|
||
File: org, Node: Checkboxes, Prev: Breaking down tasks, Up: TODO items
|
||
|
||
5.5 Checkboxes
|
||
==============
|
||
|
||
Every item in a plain list (*note Plain lists::) can be made a checkbox
|
||
by starting it with the string `[ ]'. This feature is similar to TODO
|
||
items (*note TODO items::), but more lightweight. Checkboxes are not
|
||
included into the global TODO list, so they are often great to split a
|
||
task into a number of simple steps. Or you can use them in a shopping
|
||
list. To toggle a checkbox, use `C-c C-c', or try Piotr Zielinski's
|
||
`org-mouse.el'. Here is an example of a checkbox list.
|
||
|
||
* TODO Organize party [3/6]
|
||
- call people [1/3]
|
||
- [ ] Peter
|
||
- [X] Sarah
|
||
- [ ] Sam
|
||
- [X] order food
|
||
- [ ] think about what music to play
|
||
- [X] talk to the neighbors
|
||
|
||
The `[3/6]' and `[1/3]' in the first and second line are cookies
|
||
indicating how many checkboxes are present in this entry, and how many
|
||
of them have been checked off. This can give you an idea on how many
|
||
checkboxes remain, even without opening a folded entry. The cookies
|
||
can be placed into a headline or into (the first line of) a plain list
|
||
item. Each cookie covers all checkboxes structurally below that
|
||
headline/item. You have to insert the cookie yourself by typing either
|
||
`[/]' or `[%]'. In the first case you get an `n out of m' result, in
|
||
the second case you get information about the percentage of checkboxes
|
||
checked (in the above example, this would be `[50%]' and `[33%],
|
||
respectively').
|
||
|
||
The following commands work with checkboxes:
|
||
|
||
`C-c C-c'
|
||
Toggle checkbox at point.
|
||
|
||
`C-c C-x C-b'
|
||
Toggle checkbox at point.
|
||
- If there is an active region, toggle the first checkbox in
|
||
the region and set all remaining boxes to the same status as
|
||
the first. If you want to toggle all boxes in the region
|
||
independently, use a prefix argument.
|
||
|
||
- If the cursor is in a headline, toggle checkboxes in the
|
||
region between this headline and the next (so _not_ the
|
||
entire subtree).
|
||
|
||
- If no active region, just toggle the checkbox at point.
|
||
|
||
`M-S-<RET>'
|
||
Insert a new item with a checkbox. This works only if the cursor
|
||
is already in a plain list item (*note Plain lists::).
|
||
|
||
`C-c #'
|
||
Update the checkbox statistics in the current outline entry. When
|
||
called with a `C-u' prefix, update the entire file. Checkbox
|
||
statistic cookies are updated automatically if you toggle
|
||
checkboxes with `C-c C-c' and make new ones with `M-S-<RET>'. If
|
||
you delete boxes or add/change them by hand, use this command to
|
||
get things back into synch. Or simply toggle any checkbox twice
|
||
with `C-c C-c'.

6.1 Time stamps, deadlines and scheduling
|
||
=========================================
|
||
|
||
A time stamp is a specification of a date (possibly with time) in a
|
||
special format, either `<2003-09-16 Tue>' or `<2003-09-16 Tue
|
||
09:39>'(1). A time stamp can appear anywhere in the headline or body
|
||
of an org-tree entry. Its presence allows entries to be shown on
|
||
specific dates in the agenda (*note Weekly/Daily agenda::). We
|
||
distinguish:
|
||
|
||
PLAIN TIME STAMP
|
||
A simple time stamp just assigns a date/time to an item. This is
|
||
just like writing down an appointment in a paper agenda, or like
|
||
writing down an event in a diary, when you want to take note of
|
||
when something happened. In the timeline and agenda displays, the
|
||
headline of an entry associated with a plain time stamp will be
|
||
shown exactly on that date.
|
||
|
||
* Meet Peter at the movies <2006-11-01 Wed 19:15>
|
||
|
||
INACTIVE TIME STAMP
|
||
Just like a plain time stamp, but with square brackets instead of
|
||
angular ones. These time stamps are inactive in the sense that
|
||
thay do _not_ trigger an entry to show up in the agenda.
|
||
|
||
* Gillian comes late for the fifth time [2006-11-01 Wed]
|
||
|
||
TIME STAMP RANGE
|
||
Two time stamps connected by `--' denote a time range. The
|
||
headline will be shown on the first and last day of the range, and
|
||
on any dates that are displayed and fall in the range. Here is an
|
||
example:
|
||
|
||
** Meeting in Amsterdam
|
||
<2004-08-23 Mon>--<2004-08-26 Thu>
|
||
|
||
TIME STAMP WITH SCHEDULED KEYWORD
|
||
If a time stamp is preceded by the word `SCHEDULED:', it means you
|
||
are planning to start working on that task on the given date. So
|
||
this is not about recording an event, but about planning your
|
||
work. The headline will be listed under the given date. In
|
||
addition, a reminder that the scheduled date has passed will be
|
||
present in the compilation for _today_, until the entry is marked
|
||
DONE. I.e., the task will automatically be forwarded until
|
||
completed.
|
||
|
||
*** TODO Call Trillian for a date on New Years Eve.
|
||
SCHEDULED: <2004-12-25 Sat>
|
||
|
||
TIME STAMP WITH DEADLINE KEYWORD
|
||
If a time stamp is preceded by the word `DEADLINE:', the task
|
||
(most likely a TODO item) is supposed to be finished on that date,
|
||
and it will be listed then. In addition, the compilation for
|
||
_today_ will carry a warning about the approaching or missed
|
||
deadline, starting `org-deadline-warning-days' before the due
|
||
date, and continuing until the entry is marked DONE. An example:
|
||
|
||
*** TODO write article about the Earth for the Guide
|
||
The editor in charge is <bbdb:Ford Prefect>
|
||
DEADLINE: <2004-02-29 Sun>
|
||
|
||
TIME STAMP WITH CLOSED KEYWORD
|
||
When `org-log-done' is non-nil, Org-mode will automatically insert
|
||
a special time stamp each time a TODO entry is marked done (*note
|
||
Progress logging::). This time stamp is enclosed in square
|
||
brackets instead of angular brackets.
|
||
|
||
TIME RANGE WITH CLOCK KEYWORD
|
||
When using the clock to time the work that is being done on
|
||
specific items, time ranges preceded by the CLOCK keyword are
|
||
inserted automatically into the file. The time stamps are
|
||
enclosed in square brackets instead of angular brackets. *Note
|
||
Clocking work time::.
|
||
|
||
---------- Footnotes ----------
|
||

||
6.2 Creating timestamps
|
||
=======================
|
||
|
||
For Org-mode to recognize time stamps, they need to be in the specific
|
||
format. All commands listed below produce time stamps in the correct
|
||
format.
|
||
|
||
`C-c .'
|
||
Prompt for a date and insert a corresponding time stamp. When the
|
||
cursor is at a previously used time stamp, it is updated to NOW.
|
||
When this command is used twice in succession, a time range is
|
||
inserted.
|
||
|
||
`C-u C-c .'
|
||
Like `C-c .', but use the alternative format which contains date
|
||
and time. The default time can be rounded to multiples of 5
|
||
minutes, see the option `org-time-stamp-rounding-minutes'.
|
||
|
||
`C-c !'
|
||
Like `C-c .', but insert an inactive time stamp not triggering the
|
||
agenda.
|
||
|
||
`C-c <'
|
||
Insert a time stamp corresponding to the cursor date in the
|
||
Calendar.
|
||
|
||
`C-c >'
|
||
Access the Emacs calendar for the current date. If there is a
|
||
timestamp in the current line, goto the corresponding date instead.
|
||
|
||
`C-c C-o'
|
||
Access the agenda for the date given by the time stamp or -range at
|
||
point (*note Weekly/Daily agenda::).
|
||
|
||
`C-c C-d'
|
||
Insert `DEADLINE' keyword along with a stamp. The insertion will
|
||
happen in the line directly following the headline.
|
||
|
||
`C-c C-w'
|
||
Create a sparse tree with all deadlines that are either past-due,
|
||
or which will become due within `org-deadline-warning-days'. With
|
||
`C-u' prefix, show all deadlines in the file. With a numeric
|
||
prefix, check that many days. For example, `C-1 C-c C-w' shows
|
||
all deadlines due tomorrow.
|
||
|
||
`C-c C-s'
|
||
Insert `SCHEDULED' keyword along with a stamp. The insertion will
|
||
happen in the line directly following the headline. Any CLOSED
|
||
timestamp will be removed.
|
||
|
||
`S-<left>'
|
||
`S-<right>'
|
||
Change date at cursor by one day. These key bindings conflict with
|
||
CUA-mode (*note Conflicts::).
|
||
|
||
`S-<up>'
|
||
`S-<down>'
|
||
Change the item under the cursor in a timestamp. The cursor can
|
||
be on a year, month, day, hour or minute. Note that if the cursor
|
||
is in a headline and not at a time stamp, these same keys modify
|
||
the priority of an item. (*note Priorities::). The key bindings
|
||
also conflict with CUA-mode (*note Conflicts::).
|
||
|
||
`C-c C-y'
|
||
Evaluate a time range by computing the difference between start and
|
||
end. With prefix arg, insert result after the time range (in a
|
||
table: into the following column).

|
||
|
||
6.2.1 The date/time prompt
|
||
--------------------------
|
||
|
||
When Org-mode prompts for a date/time, the prompt suggests to enter an
|
||
ISO date. But it will in fact accept any string containing some date
|
||
and/or time information. You can, for example, use `C-y' to paste a
|
||
(possibly multi-line) string copied from an email message. Org-mode
|
||
will find whatever information is in there and will replace anything not
|
||
specified with the current date and time. For example:
|
||
|
||
3-2-5 --> 2003-02-05
|
||
feb 15 --> currentyear-02-15
|
||
sep 12 9 --> 2009-09-12
|
||
12:45 --> today 12:45
|
||
22 sept 0:34 --> currentyear-09-22 0:34
|
||
12 --> currentyear-currentmonth-12
|
||
Fri --> nearest Friday (today or later)
|
||
|
||
The function understands English month and weekday abbreviations. If
|
||
you want to use unabbreviated names and/or other languages, configure
|
||
the variables `parse-time-months' and `parse-time-weekdays'.
|
||
|
||
Parallel to the minibuffer prompt, a calendar is popped up(1). You
|
||
can control the calendar fully from the minibuffer:
|
||
|
||
`<'
|
||
Scroll calendar backwards by one month.
|
||
|
||
`>'
|
||
Scroll calendar forwards by one month.
|
||
|
||
`mouse-1'
|
||
Select date by clicking on it.
|
||
|
||
`S-<right>'
|
||
One day forward.
|
||
|
||
`S-<left>'
|
||
One day back.
|
||
|
||
`S-<down>'
|
||
One week forward.
|
||
|
||
`S-<up>'
|
||
One week back.
|
||
|
||
`M-S-<right>'
|
||
One month forward.
|
||
|
||
`M-S-<left>'
|
||
One month back.
|
||
|
||
`<RET>'
|
||
Choose date in calendar (only if nothing was typed into
|
||
minibuffer).
|
||

|
||
|
||
6.3 Custom time format
|
||
======================
|
||
|
||
Org-mode uses the standard ISO notation for dates and times as it is
|
||
defined in ISO 8601. If you cannot get used to this and require another
|
||
representation of date and time to keep you happy, you can get it by
|
||
customizing the variables `org-display-custom-times' and
|
||
`org-time-stamp-custom-formats'.
|
||
|
||
`C-c C-x C-t'
|
||
Toggle the display of custom formats for dates and times.
|
||
|
||
Org-mode needs the default format for scanning, so the custom date/time
|
||
format does not _replace_ the default format - instead it is put _over_
|
||
the default format using text properties. This has the following
|
||
consequences:
|
||
* You cannot place the cursor onto a time stamp anymore, only before
|
||
or after.
|
||
|
||
* The `S-<up>/<down>' keys can no longer be used to adjust each
|
||
component of a time stamp. If the cursor is at the beginning of
|
||
the stamp, `S-<up>/<down>' will change the stamp by one day, just
|
||
like `S-<left>/<right>'. At the end of the stamp, the time will
|
||
be changed by one minute.
|
||
|
||
* When you delete a time stamp character-by-character, it will only
|
||
disappear from the buffer after _all_ (invisible) characters
|
||
belonging to the ISO timestamp have been removed.
|
||
|
||
* If the custom time stamp format is longer than the default and you
|
||
are using dates in tables, table alignment will be messed up. If
|
||
the custom format is shorter, things do work as expected.

6.4 Progress Logging
|
||
====================
|
||
|
||
Org-mode can automatically record a time stamp when you mark a TODO item
|
||
as DONE. You can also measure precisely the time you spent on specific
|
||
items in a project by starting and stopping a clock when you start and
|
||
stop working on an aspect of a project.
|
||
|
||
* Menu:
|
||
|
||
* Closing items:: When was this entry marked DONE?
|
||
* Clocking work time:: When exactly did you work on this item?
|
||
|
||
|
||
File: org, Node: Closing items, Next: Clocking work time, Prev: Progress logging, Up: Progress logging
|
||
|
||
6.4.1 Closing items
|
||
-------------------
|
||
|
||
If you want to keep track of _when_ a certain TODO item was finished,
|
||
turn on logging with
|
||
|
||
(setq org-log-done t)
|
||
|
||
Then each time you turn a TODO entry into DONE using either `C-c C-t'
|
||
in the Org-mode buffer or `t' in the agenda buffer, a line `CLOSED:
|
||
[timestamp]' will be inserted just after the headline. If you turn the
|
||
entry back into a TODO item again through further state cycling, that
|
||
line will be removed again. In the timeline (*note Timeline::) and in
|
||
the agenda (*note Weekly/Daily agenda::), you can then use the `l' key
|
||
to display the TODO items closed on each day, giving you an overview of
|
||
what has been done on a day. See the variable `org-log-done' for the
|
||
possibility to record an additional note together with a timestamp.
|
||

||

|
||
6.4.2 Clocking work time
|
||
------------------------
|
||
|
||
Org-mode allows you to clock the time you spent on specific tasks in a
|
||
project. When you start working on an item, you can start the clock.
|
||
When you stop working on that task, or when you mark the task done, the
|
||
clock is stopped and the corresponding time interval is recorded. It
|
||
also computes the total time spent on each subtree of a project.
|
||
|
||
`C-c C-x C-i'
|
||
Start the clock on the current item (clock-in). This inserts the
|
||
CLOCK keyword together with a timestamp.
|
||
|
||
`C-c C-x C-o'
|
||
Stop the clock (clock-out). The inserts another timestamp at the
|
||
same location where the clock was last started. It also directly
|
||
computes the resulting time in inserts it after the time range as
|
||
`=> HH:MM'. See the variable `org-log-done' for the possibility to
|
||
record an additional note together with a the clock-out time stamp.
|
||
|
||
`C-c C-y'
|
||
Recompute the time interval after changing one of the time stamps.
|
||
This is only necessary if you edit the time stamps directly. If
|
||
you change them with `S-<cursor>' keys, the update is automatic.
|
||
|
||
`C-c C-t'
|
||
Changing the TODO state of an item to DONE automatically stops the
|
||
clock if it is running in this same item.
|
||
|
||
`C-c C-x C-x'
|
||
Cancel the current clock. This is useful if a clock was started by
|
||
mistake, or if you ended up working on something else.
|
||
|
||
`C-c C-x C-d'
|
||
Display time summaries for each subtree in the current buffer.
|
||
This puts overlays at the end of each headline, showing the total
|
||
time recorded under that heading, including the time of any
|
||
subheadings. You can use visibility cycling to study the tree, but
|
||
the overlays disappear when you change the buffer (see variable
|
||
`org-remove-highlights-with-change') or press `C-c C-c'.
|
||
|
||
`C-c C-x C-r'
|
||
Insert a dynamic block (*note Dynamic blocks::) containing a clock
|
||
report as an org-mode table into the current file.
|
||
#+BEGIN: clocktable :maxlevel 2 :emphasize nil
|
||
|
||
#+END: clocktable
|
||
If such a block already exists, its content is replaced by the new
|
||
table. The `BEGIN' line can specify options:
|
||
:maxlevels Maximum level depth to which times are listed in the table.
|
||
:emphasize When `t', emphasize level one and level two items
|
||
:block The time block to consider. This block is specified relative
|
||
to the current time and may be any of these keywords:
|
||
`today', `yesterday', `thisweek', `lastweek',
|
||
`thismonth', `lastmonth', `thisyear', or `lastyear'.
|
||
:tstart A time string specifying when to start considering times
|
||
:tend A time string specifying when to stop considering times
|
||
So to get a clock summary for the current day, you could write
|
||
#+BEGIN: clocktable :maxlevel 2 :block today
|
||
|
||
#+END: clocktable
|
||
and to use a specific time range you could write(1)
|
||
#+BEGIN: clocktable :tstart "<2006-08-10 Thu 10:00>"
|
||
:tend "<2006-08-10 Thu 12:00>"
|
||
|
||
#+END: clocktable
|
||
|
||
`C-u C-c C-x C-u'
|
||
Update all dynamic blocks (*note Dynamic blocks::). This is
|
||
useful if you have several clocktable blocks in a buffer.
|
||
|
||
The `l' key may be used in the timeline (*note Timeline::) and in
|
||
the agenda (*note Weekly/Daily agenda::) to show which tasks have been
|
||
worked on or closed during a day.

7 Tags
|
||
******
|
||
|
||
If you wish to implement a system of labels and contexts for
|
||
cross-correlating information, an excellent way is to assign tags to
|
||
headlines. Org-mode has extensive support for using tags.
|
||
|
||
Every headline can contain a list of tags, at the end of the
|
||
headline. Tags are normal words containing letters, numbers, `_', and
|
||
`@'. Tags must be preceded and followed by a single colon; like
|
||
`:WORK:'. Several tags can be specified like `:WORK:URGENT:'.

|
||
|
||
7.1 Tag inheritance
|
||
===================
|
||
|
||
Tags make use of the hierarchical structure of outline trees. If a
|
||
heading has a certain tag, all subheadings will inherit the tag as
|
||
well. For example, in the list
|
||
|
||
* Meeting with the French group :WORK:
|
||
** Summary by Frank :BOSS:NOTES:
|
||
*** TODO Prepare slides for him :ACTION:
|
||
|
||
the final heading will have the tags `:WORK:', `:BOSS:', `:NOTES:', and
|
||
`:ACTION:'. When executing tag searches and Org-mode finds that a
|
||
certain headline matches the search criterion, it will not check any
|
||
sublevel headline, assuming that these likely also match, and that the
|
||
list of matches can become very long. This may not be what you want,
|
||
however, and you can influence inheritance and searching using the
|
||
variables `org-use-tag-inheritance' and `org-tags-match-list-sublevels'.
|
||
|
||
|
||
File: org, Node: Setting tags, Next: Tag searches, Prev: Tag inheritance, Up: Tags
|
||
|
||
7.2 Setting tags
|
||
================
|
||
|
||
Tags can simply be typed into the buffer at the end of a headline.
|
||
After a colon, `M-<TAB>' offers completion on tags. There is also a
|
||
special command for inserting tags:
|
||
|
||
`C-c C-c'
|
||
Enter new tags for the current headline. Org-mode will either
|
||
offer completion or a special single-key interface for setting
|
||
tags, see below. After pressing <RET>, the tags will be inserted
|
||
and aligned to `org-tags-column'. When called with a `C-u'
|
||
prefix, all tags in the current buffer will be aligned to that
|
||
column, just to make things look nice. TAGS are automatically
|
||
realigned after promotion, demotion, and TODO state changes (*note
|
||
TODO basics::).
|
||
|
||
Org will support tag insertion based on a _list of tags_. By
|
||
default this list is constructed dynamically, containing all tags
|
||
currently used in the buffer. You may also globally specify a hard list
|
||
of tags with the variable `org-tag-alist'. Finally you can set the
|
||
default tags for a given file with lines like
|
||
|
||
#+TAGS: @WORK @HOME @TENNISCLUB
|
||
#+TAGS: Laptop Car PC Sailboat
|
||
|
||
If you have globally defined your preferred set of tags using the
|
||
variable `org-tag-alist', but would like to use a dynamic tag list in a
|
||
specific file: Just add an empty TAGS option line to that file:
|
||
|
||
#+TAGS:
|
||
|
||
The default support method for entering tags is minibuffer
|
||
completion. However, Org-mode also implements a much better method:
|
||
_fast tag selection_. This method allows to select and deselect tags
|
||
with a single key per tag. To function efficiently, you should assign
|
||
unique keys to most tags. This can be done globally with
|
||
|
||
(setq org-tag-alist '(("@WORK" . ?w) ("@HOME" . ?h) ("Laptop" . ?l)))
|
||
|
||
or on a per-file basis with
|
||
|
||
#+TAGS: @WORK(w) @HOME(h) @TENNISCLUB(t) Laptop(l) PC(p)
|
||
|
||
You can also group together tags that are mutually exclusive. With
|
||
curly braces(1)
|
||
|
||
#+TAGS: { @WORK(w) @HOME(h) @TENNISCLUB(t) } Laptop(l) PC(p)
|
||
|
||
you indicate that at most one of `@WORK', `@HOME', and `@TENNISCLUB'
|
||
should be selected.
|
||
|
||
Don't forget to press `C-c C-c' with the cursor in one of these lines
|
||
to activate any changes.
|
||
|
||
If at least one tag has a selection key, pressing `C-c C-c' will
|
||
automatically present you with a special interface, listing inherited
|
||
tags, the tags of the current headline, and a list of all legal tags
|
||
with corresponding keys(2). In this interface, you can use the
|
||
following keys:
|
||
|
||
`a-z...'
|
||
Pressing keys assigned to tags will add or remove them from the
|
||
list of tags in the current line. Selecting a tag in a group of
|
||
mutually exclusive tags will turn off any other tags from that
|
||
group.
|
||
|
||
`<TAB>'
|
||
Enter a tag in the minibuffer, even if the tag is not in the
|
||
predefined list. You will be able to complete on all tags present
|
||
in the buffer.
|
||
|
||
`<SPC>'
|
||
Clear all tags for this line.
|
||
|
||
`<RET>'
|
||
Accept the modified set.
|
||
|
||
`C-g'
|
||
Abort without installing changes.
|
||
|
||
This method lets you assign tags to a headline with very few keys. With
|
||
the above setup, you could clear the current tags and set `@HOME',
|
||
`Laptop' and `PC' tags with just the following keys: `C-c C-c <SPC> h l
|
||
p <RET>'. Switching from `@HOME' to `@WORK' would be done with `C-c
|
||
C-c w <RET>'. Adding the non-predefined tag `Sarah' could be done with
|
||
`C-c C-c <TAB> S a r a h <RET> <RET>'.
|
||
|
||
---------- Footnotes ----------
|
||

||
(1) In `org-mode-alist' use `'(:startgroup)' and `'(:endgroup)',
|
||
respectively. Several groups are allowed.

configured keys.

7.3 Tag searches
|
||
================
|
||
|
||
Once a tags system has been set up, it can be used to collect related
|
||
information into special lists.
|
||
|
||
`C-c \'
|
||
Create a sparse tree with all headlines matching a tags search.
|
||
|
||
`C-c a m'
|
||
Create a global list of tag matches from all agenda files. *Note
|
||
Matching headline tags::.
|
||
|
||
`C-c a M'
|
||
Create a global list of tag matches from all agenda files, but
|
||
check only TODO items and force checking subitems (see variable
|
||
`org-tags-match-list-sublevels').
|
||
|
||
A tags search string can use Boolean operators `&' for AND and `|'
|
||
for OR. `&' binds more strongly than `|'. Parenthesis are currently
|
||
not implemented. A tag may also be preceded by `-', to select against
|
||
it, and `+' is syntactic sugar for positive selection. The AND
|
||
operator `&' is optional when `+' or `-' is present. Examples:
|
||
|
||
`+WORK-BOSS'
|
||
Select all headlines that are tagged `:WORK:', but discard those
|
||
also tagged `:BOSS:'.
|
||
|
||
`WORK|LAPTOP'
|
||
Selects lines tagged `:WORK:' or `:LAPTOP:'.
|
||
|
||
`WORK|LAPTOP&NIGHT'
|
||
Like the previous example, but require the `:LAPTOP:' lines to be
|
||
tagged also `NIGHT'.
|
||
|
||
If you are using multi-state TODO keywords (*note TODO
|
||
extensions::), it can be useful to also match on the TODO keyword.
|
||
This can be done by adding a condition after a slash to a tags match.
|
||
The syntax is similar to the tag matches, but should be applied with
|
||
consideration: For example, a positive selection on several TODO
|
||
keywords can not meaningfully be combined with boolean AND. However,
|
||
_negative selection_ combined with AND can be meaningful. Examples:
|
||
|
||
`WORK/WAITING'
|
||
Select `:WORK:'-tagged TODO lines with the specific TODO keyword
|
||
`WAITING'.
|
||
|
||
`WORK/-WAITING-NEXT'
|
||
Select `:WORK:'-tagged TODO lines that are neither `WAITING' nor
|
||
`NEXT'
|
||
|
||
`WORK/+WAITING|+NEXT'
|
||
Select `:WORK:'-tagged TODO lines that are either `WAITING' or
|
||
`NEXT'.

8 Agenda Views
|
||
**************
|
||
|
||
Due to the way Org-mode works, TODO items, time-stamped items, and
|
||
tagged headlines can be scattered throughout a file or even a number of
|
||
files. To get an overview over open action items, or over events that
|
||
are important for a particular date, this information must be collected,
|
||
sorted and displayed in an organized way.
|
||
|
||
Org-mode can select items based on various criteria, and display them
|
||
in a separate buffer. Five different view types are provided:
|
||
|
||
* an _agenda_ that is like a calendar and shows information for
|
||
specific dates
|
||
|
||
* a _TODO list_ that covers all unfinished action items,
|
||
|
||
* a _tags view_ that shows information based on the tags associated
|
||
with headlines in the outline tree,
|
||
|
||
* a _timeline view_ that shows all events in a single Org-mode file,
|
||
in time-sorted view
|
||
|
||
* _custom views_ that are special tag and keyword searches and
|
||
combinations of different views.
|
||
|
||
The extracted information is displayed in a special _agenda buffer_.
|
||
This buffer is read-only, but provides commands to visit the
|
||
corresponding locations in the original Org-mode files, and even to
|
||
edit these files remotely.
|
||
|
||
Two variables control how the agenda buffer is displayed and whether
|
||
the window configuration is restored when the agenda exits:
|
||
`org-agenda-window-setup' and `org-agenda-restore-windows-after-quit'.

8.1 Agenda files
|
||
================
|
||
|
||
The information to be shown is collected from all _agenda files_, the
|
||
files listed in the variable `org-agenda-files'(1). Thus even if you
|
||
only work with a single Org-mode file, this file should be put into
|
||
that list(2). You can customize `org-agenda-files', but the easiest
|
||
way to maintain it is through the following commands
|
||
|
||
`C-c ['
|
||
Add current file to the list of agenda files. The file is added to
|
||
the front of the list. If it was already in the list, it is moved
|
||
to the front. With prefix arg, file is added/moved to the end.
|
||
|
||
`C-c ]'
|
||
Remove current file from the list of agenda files.
|
||
|
||
`C-,'
|
||
Cycle through agenda file list, visiting one file after the other.
|
||
|
||
The Org menu contains the current list of files and can be used to
|
||
visit any of them.
|
||
|
||
---------- Footnotes ----------
|
||
|
||
(1) If the value of that variable is not a list, but a single file
|
||
name, then the list of agenda files will be maintained in that external
|
||
file.
|
||
|
||
(2) When using the dispatcher, pressing `1' before selecting a
|
||
command will actually limit the command to the current file, and ignore
|
||
`org-agenda-files' until the next dispatcher command.

8.2 The agenda dispatcher
|
||
=========================
|
||
|
||
The views are created through a dispatcher that should be bound to a
|
||
global key, for example `C-c a' (*note Installation::). In the
|
||
following we will assume that `C-c a' is indeed how the dispatcher is
|
||
accessed and list keyboard access to commands accordingly. After
|
||
pressing `C-c a', an additional letter is required to execute a
|
||
command. The dispatcher offers the following default commands:
|
||
`a'
|
||
Create the calendar-like agenda (*note Weekly/Daily agenda::).
|
||
|
||
`t / T'
|
||
Create a list of all TODO items (*note Global TODO list::).
|
||
|
||
`m / M'
|
||
Create a list of headlines matching a TAGS expression (*note
|
||
Matching headline tags::).
|
||
|
||
`L'
|
||
Create the timeline view for the current buffer (*note Timeline::).
|
||
|
||
`1'
|
||
Restrict an agenda command to the current buffer. After pressing
|
||
`1', you still need to press the character selecting the command.
|
||
|
||
`0'
|
||
If there is an active region, restrict the following agenda
|
||
command to the region. Otherwise, restrict it to the current
|
||
subtree. After pressing `0', you still need to press the
|
||
character selecting the command.
|
||
|
||
You can also define custom commands that will be accessible through
|
||
the dispatcher, just like the default commands. This includes the
|
||
possibility to create extended agenda buffers that contain several
|
||
blocks together, for example the weekly agenda, the global TODO list and
|
||
a number of special tags matches. *Note Custom agenda views::.

|
||
|
||
8.3 The weekly/daily agenda
|
||
===========================
|
||
|
||
The purpose of the weekly/daily _agenda_ is to act like a page of a
|
||
paper agenda, showing all the tasks for the current week or day.
|
||
|
||
`C-c a a'
|
||
Compile an agenda for the current week from a list of org files.
|
||
The agenda shows the entries for each day. With a `C-u' prefix (or
|
||
when the variable `org-agenda-include-all-todo' is `t'), all
|
||
unfinished TODO items (including those without a date) are also
|
||
listed at the beginning of the buffer, before the first date.
|
||
|
||
Remote editing from the agenda buffer means, for example, that you
|
||
can change the dates of deadlines and appointments from the agenda
|
||
buffer. The commands available in the Agenda buffer are listed in
|
||
*Note Agenda commands::.

8.3.1 Calendar/Diary integration
|
||
--------------------------------
|
||
|
||
Emacs contains the calendar and diary by Edward M. Reingold. The
|
||
calendar displays a three-month calendar with holidays from different
|
||
countries and cultures. The diary allows you to keep track of
|
||
anniversaries, lunar phases, sunrise/set, recurrent appointments
|
||
(weekly, monthly) and more. In this way, it is quite complementary to
|
||
Org-mode. It can be very useful to combine output from Org-mode with
|
||
the diary.
|
||
|
||
In order to include entries from the Emacs diary into Org-mode's
|
||
agenda, you only need to customize the variable
|
||
|
||
(setq org-agenda-include-diary t)
|
||
|
||
After that, everything will happen automatically. All diary entries
|
||
including holidays, anniversaries etc will be included in the agenda
|
||
buffer created by Org-mode. <SPC>, <TAB>, and <RET> can be used from
|
||
the agenda buffer to jump to the diary file in order to edit existing
|
||
diary entries. The `i' command to insert new entries for the current
|
||
date works in the agenda buffer, as well as the commands `S', `M', and
|
||
`C' to display Sunrise/Sunset times, show lunar phases and to convert
|
||
to other calendars, respectively. `c' can be used to switch back and
|
||
forth between calendar and agenda.

||
8.4 The global TODO list
|
||
========================
|
||
|
||
The global TODO list contains all unfinished TODO items, formatted and
|
||
collected into a single place.
|
||
|
||
`C-c a t'
|
||
Show the global TODO list. This collects the TODO items from all
|
||
agenda files (*note Agenda views::) into a single buffer. The
|
||
buffer is in `agenda-mode', so there are commands to examine and
|
||
manipulate the TODO entries directly from that buffer (*note
|
||
Agenda commands::).
|
||
|
||
`C-c a T'
|
||
Like the above, but allows selection of a specific TODO keyword.
|
||
You can also do this by specifying a prefix argument to `C-c a t'.
|
||
With a `C-u' prefix you are prompted for a keyword. With a
|
||
numeric prefix, the Nth keyword in `org-todo-keywords' is selected. The
|
||
`r' key in the agenda buffer regenerates it, and you can give a
|
||
prefix argument to this command to change the selected TODO
|
||
keyword, for example `3 r'. If you often need a search for a
|
||
specific keyword, define a custom command for it (*note Agenda
|
||
dispatcher::).
|
||
Matching specific TODO keywords can also be done as part of a tags
|
||
search (*note Tag searches::).
|
||
|
||
Remote editing of TODO items means that you can change the state of a
|
||
TODO entry with a single key press. The commands available in the TODO
|
||
list are described in *Note Agenda commands::.
|
||
|
||
Normally the global todo list simply shows all headlines with TODO
|
||
keywords. This list can become very long. There are two ways to keep
|
||
it more compact:
|
||
- Some people view a TODO item that has been _scheduled_ for
|
||
execution (*note Time stamps::) as no longer _open_. Configure the
|
||
variable `org-agenda-todo-ignore-scheduled' to exclude scheduled
|
||
items from the global TODO list.
|
||
|
||
- TODO items may have sublevels to break up the task into subtasks.
|
||
In such cases it may be enough to list only the highest level TODO
|
||
headline and omit the sublevels from the global list. Configure
|
||
the variable `org-agenda-todo-list-sublevels' to get this behavior.
|
||

|
||
|
||
8.5 Matching headline tags
|
||
==========================
|
||
|
||
If headlines in the agenda files are marked with _tags_ (*note Tags::),
|
||
you can select headlines based on the tags that apply to them and
|
||
collect them into an agenda buffer.
|
||
|
||
`C-c a m'
|
||
Produce a list of all headlines that match a given set of tags.
|
||
The command prompts for a selection criterion, which is a boolean
|
||
logic expression with tags, like `+WORK+URGENT-WITHBOSS' or
|
||
`WORK|HOME' (*note Tags::). If you often need a specific search,
|
||
define a custom command for it (*note Agenda dispatcher::).
|
||
|
||
`C-c a M'
|
||
Like `C-c a m', but only select headlines that are also TODO items
|
||
and force checking subitems (see variable
|
||
`org-tags-match-list-sublevels'). Matching specific todo keywords
|
||
together with a tags match is also possible, see *Note Tag
|
||
searches::.
|
||
|
||
The commands available in the tags list are described in *Note
|
||
Agenda commands::.

|
||
|
||
8.6 Timeline for a single file
|
||
==============================
|
||
|
||
The timeline summarizes all time-stamped items from a single Org-mode
|
||
file in a _time-sorted view_. The main purpose of this command is to
|
||
give an overview over events in a project.
|
||
|
||
`C-c a L'
|
||
Show a time-sorted view of the org file, with all time-stamped
|
||
items. When called with a `C-u' prefix, all unfinished TODO
|
||
entries (scheduled or not) are also listed under the current date.
|
||
|
||
The commands available in the timeline buffer are listed in *Note
|
||
Agenda commands::.

||
8.7 Presentation and sorting
|
||
============================
|
||
|
||
Before displaying items in an agenda view, Org-mode visually prepares
|
||
the items and sorts them. Each item occupies a single line. The line
|
||
starts with a _prefix_ that contains the _category_ (*note
|
||
Categories::) of the item and other important information. You can
|
||
customize the prefix using the option `org-agenda-prefix-format'. The
|
||
prefix is followed by a cleaned-up version of the outline headline
|
||
associated with the item.
|
||
|
||
* Menu:
|
||
|
||
* Categories:: Not all tasks are equal
|
||
* Time-of-day specifications:: How the agenda knows the time
|
||
* Sorting of agenda items:: The order of things
|
||
|
||
|
||
File: org, Node: Categories, Next: Time-of-day specifications, Prev: Presentation and sorting, Up: Presentation and sorting
|
||
|
||
8.7.1 Categories
|
||
----------------
|
||
|
||
The category is a broad label assigned to each agenda item. By default,
|
||
the category is simply derived from the file name, but you can also
|
||
specify it with a special line in the buffer, like this:
|
||
|
||
#+CATEGORY: Thesis
|
||
|
||
If there are several such lines in a file, each specifies the
|
||
category for the text below it (but the first category also applies to
|
||
any text before the first CATEGORY line). The display in the agenda
|
||
buffer looks best if the category is not longer than 10 characters.
|
||
|
||
|
||

|
||
|
||
8.7.2 Time-of-Day Specifications
|
||
--------------------------------
|
||
|
||
Org-mode checks each agenda item for a time-of-day specification. The
|
||
time can be part of the time stamp that triggered inclusion into the
|
||
agenda, for example as in `<2005-05-10 Tue 19:00>'. Time ranges can be
|
||
specified with two time stamps, like
|
||
`<2005-05-10 Tue 20:30>--<2005-05-10 Tue 22:15>'.
|
||
|
||
In the headline of the entry itself, a time(range) may also appear as
|
||
plain text (like `12:45' or a `8:30-1pm'. If the agenda integrates the
|
||
Emacs diary (*note Calendar/Diary integration::), time specifications
|
||
in diary entries are recognized as well.
|
||
|
||
For agenda display, Org-mode extracts the time and displays it in a
|
||
standard 24 hour format as part of the prefix. The example times in
|
||
the previous paragraphs would end up in the agenda like this:
|
||
|
||
8:30-13:00 Arthur Dent lies in front of the bulldozer
|
||
12:45...... Ford Prefect arrives and takes Arthur to the pub
|
||
19:00...... The Vogon reads his poem
|
||
20:30-22:15 Marwin escorts the Hitchhikers to the bridge
|
||
|
||
If the agenda is in single-day mode, or for the display of today, the
|
||
timed entries are embedded in a time grid, like
|
||
|
||
8:00...... ------------------
|
||
8:30-13:00 Arthur Dent lies in front of the bulldozer
|
||
10:00...... ------------------
|
||
12:00...... ------------------
|
||
12:45...... Ford Prefect arrives and takes Arthur to the pub
|
||
14:00...... ------------------
|
||
16:00...... ------------------
|
||
18:00...... ------------------
|
||
19:00...... The Vogon reads his poem
|
||
20:00...... ------------------
|
||
20:30-22:15 Marwin escorts the Hitchhikers to the bridge
|
||
|
||
The time grid can be turned on and off with the variable
|
||
`org-agenda-use-time-grid', and can be configured with
|
||
`org-agenda-time-grid'.

||
8.7.3 Sorting of agenda items
|
||
-----------------------------
|
||
|
||
Before being inserted into a view, the items are sorted. How this is
|
||
done depends on the type of view.
|
||
* For the daily/weekly agenda, the items for each day are sorted.
|
||
The default order is to first collect all items containing an
|
||
explicit time-of-day specification. These entries will be shown
|
||
at the beginning of the list, as a _schedule_ for the day. After
|
||
that, items remain grouped in categories, in the sequence given by
|
||
`org-agenda-files'. Within each category, items are sorted by
|
||
priority (*note Priorities::), which is composed of the base
|
||
priority (2000 for priority `A', 1000 for `B', and 0 for `C'),
|
||
plus additional increments for overdue scheduled or deadline items.
|
||
|
||
* For the TODO list, items remain in the order of categories, but
|
||
within each category, sorting takes place according to priority
|
||
(*note Priorities::).
|
||
|
||
* For tags matches, items are not sorted at all, but just appear in
|
||
the sequence in which they are found in the agenda files.
|
||
|
||
Sorting can be customized using the variable
|
||
`org-agenda-sorting-strategy'.

8.8 Commands in the agenda buffer
|
||
=================================
|
||
|
||
Entries in the agenda buffer are linked back to the org file or diary
|
||
file where they originate. You are not allowed to edit the agenda
|
||
buffer itself, but commands are provided to show and jump to the
|
||
original entry location, and to edit the org-files "remotely" from the
|
||
agenda buffer. In this way, all information is stored only once,
|
||
removing the risk that your agenda and note files may diverge.
|
||
|
||
Some commands can be executed with mouse clicks on agenda lines. For
|
||
the other commands, the cursor needs to be in the desired line.
|
||

`<RET>'
|
||
Go to the original location of the item and delete other windows.
|
||
|
||
`f'
|
||
Toggle Follow mode. In Follow mode, as you move the cursor through
|
||
the agenda buffer, the other window always shows the corresponding
|
||
location in the org file. The initial setting for this mode in new
|
||
agenda buffers can be set with the variable
|
||
`org-agenda-start-with-follow-mode'.
|
||
|
||
`l'
|
||
Toggle Logbook mode. In Logbook mode, entries that where marked
|
||
DONE while logging was on (variable `org-log-done') are shown in
|
||
the agenda, as are entries that have been clocked on that day.

|
||
`org-agenda-use-time-grid' and `org-agenda-time-grid'.
|
||
|
||
`r'
|
||
Recreate the agenda buffer, for example to reflect the changes
|
||
after modification of the time stamps of items with S-<left> and
|
||
S-<right>. When the buffer is the global todo list, a prefix
|
||
argument is interpreted to create a selective list for a specific
|
||
TODO keyword.
|
||
|
||
`s'
|
||
Save all Org-mode buffers in the current Emacs session.
|
||

|
||
Display the following `org-agenda-ndays' days. For example, if
|
||
the display covers a week, switch to the following week. With
|
||
prefix arg, go forward that many times `org-agenda-ndays' days.
|
||
|
||
`<left>'
|

|
||
is removed from the entry.
|
||
|
||
`p'
|
||
Display weighted priority of current item.
|
||
|
||
`+'
|
||

|
||
Set a deadline for this item.
|
||
|
||
`S-<right>'
|
||
Change the time stamp associated with the current line by one day
|
||
into the future. With prefix argument, change it by that many
|
||
days. For example, `3 6 5 S-<right>' will change it by a year.
|
||
The stamp is changed in the original org file, but the change is
|
||
not directly reflected in the agenda buffer. Use the `r' key to
|
||
update the buffer.
|
||
|
||
`S-<left>'
|
||
Change the time stamp associated with the current line by one day
|
||
into the past.
|
||
|
||
`>'
|
||
Change the time stamp associated with the current line to today.
|
||
The key `>' has been chosen, because it is the same as `S-.' on my
|
||
keyboard.
|
||
|
||
`I'
|
||
Start the clock on the current item. If a clock is running
|
||
already, it is stopped first.
|
||
|
||
`O'
|
||
Stop the previously started clock.

8.9 Custom agenda views
|
||
=======================
|
||
|
||
Custom agenda commands serve two purposes: to store and quickly access
|
||
frequently used TODO and tags searches, and to create special composite
|
||
agenda buffers. Custom agenda commands will be accessible through the
|
||
dispatcher (*note Agenda dispatcher::), just like the default commands.
|
||
|
||

|
||
|
||
* Storing searches:: Type once, use often
|
||
* Block agenda:: All the stuff you need in a single buffer
|
||
* Setting Options:: Changing the rules
|
||
* Batch processing:: Agenda views from the command line
|
||

||
File: org, Node: Storing searches, Next: Block agenda, Prev: Custom agenda views, Up: Custom agenda views
|
||
|
||
8.9.1 Storing searches
|
||
----------------------
|
||
|
||
The first application of custom searches is the definition of keyboard
|
||
shortcuts for frequently used searches, either creating an agenda
|
||
buffer, or a sparse tree (the latter covering of course only the current
|
||
buffer). Custom commands are configured in the variable
|
||
`org-agenda-custom-commands'. You can customize this variable, for
|
||
example by pressing `C-c a C'. You can also directly set it with Emacs
|
||
Lisp in `.emacs'. The following example contains all valid search
|
||
types:
|
||
|
||
(setq org-agenda-custom-commands
|
||
'(("w" todo "WAITING")
|
||
("W" todo-tree "WAITING")
|
||
("u" tags "+BOSS-URGENT")
|
||
("v" tags-todo "+BOSS-URGENT")
|
||
("U" tags-tree "+BOSS-URGENT")
|
||
("f" occur-tree "\\<FIXME\\>")))
|
||
|
||
The initial single-character string in each entry defines the character
|
||
you have to press after the dispatcher command `C-c a' in order to
|
||
access the command. The second parameter is the search type, followed
|
||
by the string or regular expression to be used for the matching. The
|
||
example above will therefore define:
|
||
|
||
`C-c a w'
|
||
as a global search for TODO entries with `WAITING' as the TODO
|
||
keyword
|
||
|
||
`C-c a W'
|
||
as the same search, but only in the current buffer and displaying
|
||
the results as a sparse tree
|
||
|
||
`C-c a u'
|
||
as a global tags search for headlines marked `:BOSS:' but not
|
||
`:URGENT:'
|
||
|
||
`C-c a v'
|
||
as the same search as `C-c a u', but limiting the search to
|
||
headlines that are also TODO items
|
||
|
||
`C-c a U'
|
||
as the same search as `C-c a u', but only in the current buffer and
|
||
displaying the result as a sparse tree
|
||
|
||
`C-c a f'
|
||
to create a sparse tree (again: current buffer only) with all
|
||
entries containing the word `FIXME'.
|
||

||

||

|
||
|
||
8.9.2 Block agenda
|
||
------------------
|
||
|
||
Another possibility is the construction of agenda views that comprise
|
||
the results of _several_ commands, each of which creates a block in the
|
||
agenda buffer. The available commands include `agenda' for the daily
|
||
or weekly agenda (as created with `C-c a a'), `alltodo' for the global
|
||
todo list (as constructed with `C-c a t'), and the matching commands
|
||
discussed above: `todo', `tags', and `tags-todo'. Here are two
|
||
examples:
|
||
|
||
(setq org-agenda-custom-commands
|
||
'(("h" "Agenda and Home-related tasks"
|
||
((agenda)
|
||
(tags-todo "HOME")
|
||
(tags "GARDEN")))
|
||
("o" "Agenda and Office-related tasks"
|
||
((agenda)
|
||
(tags-todo "WORK")
|
||
(tags "OFFICE")))))
|
||
|
||
This will define `C-c a h' to create a multi-block view for stuff you
|
||
need to attend to at home. The resulting agenda buffer will contain
|
||
your agenda for the current week, all TODO items that carry the tag
|
||
`HOME', and also all lines tagged with `GARDEN'. Finally the command
|
||
`C-c a o' provides a similar view for office tasks.

|
||
|
||
8.9.3 Setting Options for custom commands
|
||
-----------------------------------------
|
||
|
||
Org-mode contains a number of variables regulating agenda construction
|
||
and display. The global variables define the behavior for all agenda
|
||
commands, including the custom commands. However, if you want to change
|
||
some settings just for a single custom view, you can do so. Setting
|
||
options requires inserting a list of variable names and values at the
|
||
right spot in `org-agenda-custom-commands'. For example:
|
||
|
||
(setq org-agenda-custom-commands
|
||
'(("w" todo "WAITING"
|
||
((org-agenda-sorting-strategy '(priority-down))
|
||
(org-agenda-prefix-format " Mixed: ")))
|
||
("U" tags-tree "+BOSS-URGENT"
|
||
((org-show-following-heading nil)
|
||
(org-show-hierarchy-above nil)))))
|
||
|
||
Now the `C-c a w' command will sort the collected entries only by
|
||
priority, and the prefix format is modified to just say ` Mixed:'
|
||
instead of giving the category of the entry. The sparse tags tree of
|
||
`C-c a U' will now turn out ultra-compact, because neither the headline
|
||
hierarchy above the match, nor the headline following the match will be
|
||
shown.
|
||
|
||
For command sets creating a block agenda,
|
||
`org-agenda-custom-commands' has two separate spots for setting
|
||
options. You can add options that should be valid for just a single
|
||
command in the set, and options that should be valid for all commands in
|
||
the set. The former are just added to the command entry, the latter
|
||
must come after the list of command entries. Going back to the block
|
||
agenda example (*note Block agenda::), let's change the sorting strategy
|
||
for the `C-c a h' commands to `priority-down', but let's sort the
|
||
results for GARDEN tags query in the opposite order, `priority-up'.
|
||
This would look like this:
|
||
|
||
(setq org-agenda-custom-commands
|
||
'(("h" "Agenda and Home-related tasks"
|
||
((agenda)
|
||
(tags-todo "HOME")
|
||
(tags "GARDEN" ((org-agenda-sorting-strategy '(priority-up)))))
|
||
((org-agenda-sorting-strategy '(priority-down))))
|
||
("o" "Agenda and Office-related tasks"
|
||
((agenda)
|
||
(tags-todo "WORK")
|
||
(tags "OFFICE")))))
|
||
|
||
As you see, the values and parenthesis setting is a little complex.
|
||
When in doubt, use the customize interface to set this variable - it
|
||
fully supports its structure. Just one caveat: When setting options in
|
||
this interface, the _values_ are just lisp expressions. So if the
|
||
value is a string, you need to add the double quotes around the value
|
||
yourself.

8.9.4 Creating agenda views in batch processing
|
||
-----------------------------------------------
|
||
|
||
If you want to print or otherwise reprocess agenda views, it can be
|
||
useful to create an agenda from the command line. This is the purpose
|
||
of the function `org-batch-agenda'. It takes as a parameter one of the
|
||
strings that are the keys in `org-agenda-custom-commands'. For
|
||
example, to directly print the current TODO list, you could use
|
||
|
||
emacs -batch -l ~/.emacs -eval '(org-batch-agenda "t")' | lpr
|
||
|
||
You may also modify parameters on the fly like this:
|
||
|
||
emacs -batch -l ~/.emacs \
|
||
-eval '(org-batch-agenda "a" \
|
||
org-agenda-ndays 300 \
|
||
org-agenda-include-diary nil \
|
||
org-agenda-files (quote ("~/org/project.org")))' \
|
||
| lpr
|
||
|
||
which will produce a 300 day agenda, fully restricted to the Org file
|
||
`~/org/projects.org', not even including the diary.

9 Embedded LaTeX
|
||
****************
|
||
|
||
Plain ASCII is normally sufficient for almost all note taking. One
|
||
exception, however, are scientific notes which need to be able to
|
||
contain mathematical symbols and the occasional formula. LaTeX(1) is
|
||
widely used to typeset scientific documents. Org-mode supports
|
||
embedding LaTeX code into its files, because many academics are used to
|
||
read LaTeX source code, and because it can be readily processed into
|
||
images for HTML production.
|
||
|
||
It is not necessary to mark LaTeX macros and code in any special way.
|
||
If you observe a few conventions, Org-mode knows how to find it and what
|
||
to do with it.

---------- Footnotes ----------
|
||
|
||
(1) LaTeX is a macro system based on Donald E. Knuth's TeX system.
|
||
Many of the features described here as "LaTeX" are really from TeX, but
|
||
for simplicity I am blurring this distinction.
|
||
|
||
|
||

|
||
|
||
9.1 Math symbols
|
||
================
|
||
|
||
You can use LaTeX macros to insert special symbols like `\alpha' to
|
||
indicate the Greek letter, or `\to' to indicate an arrow. Completion
|
||
for these macros is available, just type `\' and maybe a few letters,
|
||
and press `M-<TAB>' to see possible completions. Unlike LaTeX code,
|
||
Org-mode allows these macros to be present without surrounding math
|
||
delimiters, for example:
|
||
|
||
Angles are written as Greek letters \alpha, \beta and \gamma.
|
||
|
||
During HTML export (*note HTML export::), these symbols are
|
||
translated into the proper syntax for HTML, for the above examples this
|
||
is `α' and `→', respectively.
|
||
|
||
|
||
File: org, Node: Subscripts and Superscripts, Next: LaTeX fragments, Prev: Math symbols, Up: Embedded LaTeX
|
||
|
||
9.2 Subscripts and Superscripts
|
||
===============================
|
||
|
||
Just like in LaTeX, `^' and `_' are used to indicate super- and
|
||
subscripts. Again, these can be used without embedding them in
|
||
math-mode delimiters. To increase the readability of ASCII text, it is
|
||
not necessary (but OK) to surround multi-character sub- and superscripts
|
||
with curly braces. For example
|
||
|
||
The mass if the sun is M_sun = 1.989 x 10^30 kg. The radius of
|
||
the sun is R_{sun} = 6.96 x 10^8 m.
|
||
|
||
To avoid interpretation as raised or lowered text, you can quote `^'
|
||
and `_' with a backslash: `\_' and `\^'.
|
||
|
||
During HTML export (*note HTML export::), subscript and superscripts
|
||
are surrounded with `<sub>' and `<sup>' tags, respectively.
|
||
|
||
|
||
File: org, Node: LaTeX fragments, Next: Processing LaTeX fragments, Prev: Subscripts and Superscripts, Up: Embedded LaTeX
|
||
|
||
9.3 LaTeX fragments
|
||
===================
|
||
|
||
With symbols, sub- and superscripts, HTML is pretty much at its end when
|
||
it comes to representing mathematical formulas(1). More complex
|
||
expressions need a dedicated formula processor. To this end, Org-mode
|
||
can contain arbitrary LaTeX fragments. It provides commands to preview
|
||
the typeset result of these fragments, and upon export to HTML, all
|
||
fragments will be converted to images and inlined into the HTML
|
||
document. For this to work you need to be on a system with a working
|
||
LaTeX installation. You also need the `dvipng' program, available at
|
||
`http://sourceforge.net/projects/dvipng/'.
|
||
|
||
LaTeX fragments don't need any special marking at all. The following
|
||
snippets will be identified as LaTeX source code:
|
||
* Environments of any kind. The only requirement is that the
|
||
`\begin' statement appears on a new line, preceded by only
|
||
whitespace.
|
||
|
||
* Text within the usual LaTeX math delimiters. To avoid conflicts
|
||
with currency specifications, single `$' characters are only
|
||
recognized as math delimiters if the enclosed text contains at
|
||
most two line breaks, is directly attached to the `$' characters
|
||
with no whitespace in between, and if the closing `$' is followed
|
||
by whitespace or punctuation. For the other delimiters, there is
|
||
no such restriction, so when in doubt, use `\(...\)' as inline
|
||
math delimiters.
|
||
|
||
For example:
|
||
|
||
\begin{equation} % arbitrary environments,
|
||
x=\sqrt{b} % even tables, figures
|
||
\end{equation} % etc
|
||
|
||
If $a^2=b$ and \( b=2 \), then the solution must be
|
||
either $$ a=+\sqrt{2} $$ or \[ a=-\sqrt{2} \].
|
||
|
||
If you need any of the delimiter ASCII sequences for other purposes, you
|
||
can configure the option `org-format-latex-options' to deselect the
|
||
ones you do not wish to have interpreted by the LaTeX converter.
|
||
|
||
---------- Footnotes ----------
|
||
|
||
(1) Yes, there is MathML, but that is not yet fully supported by
|
||
many browsers, and there is no decent converter for turning LaTeX of
|
||
ASCII representations of formulas into MathML. So for the time being,
|
||
converting formulas into images seems the way to go.
|
||
|
||
|
||
File: org, Node: Processing LaTeX fragments, Next: CDLaTeX mode, Prev: LaTeX fragments, Up: Embedded LaTeX
|
||
|
||
9.4 Processing LaTeX fragments
|
||
==============================
|
||
|
||
LaTeX fragments can be processed to produce a preview images of the
|
||
typeset expressions:
|
||
|
||
`C-c C-x C-l'
|
||
Produce a preview image of the LaTeX fragment at point and overlay
|
||
it over the source code. If there is no fragment at point,
|
||
process all fragments in the current entry (between two
|
||
headlines). When called with a prefix argument, process the
|
||
entire subtree. When called with two prefix arguments, or when
|
||
the cursor is before the first headline, process the entire buffer.
|
||
|
||
`C-c C-c'
|
||
Remove the overlay preview images.
|
||
|
||
During HTML export (*note HTML export::), all LaTeX fragments are
|
||
converted into images and inlined into the document if the following
|
||
setting is active:
|
||
|
||
(setq org-export-with-LaTeX-fragments t)
|
||
|
||
|
||
File: org, Node: CDLaTeX mode, Prev: Processing LaTeX fragments, Up: Embedded LaTeX
|
||
|
||
9.5 Using CDLaTeX to enter math
|
||
===============================
|
||
|
||
CDLaTeX-mode is a minor mode that is normally used in combination with a
|
||
major LaTeX mode like AUCTeX in order to speed-up insertion of
|
||
environments and math templates. Inside Org-mode, you can make use of
|
||
some of the features of cdlatex-mode. You need to install `cdlatex.el'
|
||
and `texmathp.el' (the latter comes also with AUCTeX) from
|
||
`http://www.astro.uva.nl/~dominik/Tools/cdlatex'. Don't turn
|
||
cdlatex-mode itself under Org-mode, but use the light version
|
||
`org-cdlatex-mode' that comes as part of Org-mode. Turn it on for the
|
||
current buffer with `M-x org-cdlatex-mode', or for all Org-mode files
|
||
with
|
||
|
||
(add-hook 'org-mode-hook 'turn-on-org-cdlatex)
|
||
|
||
When this mode is enabled, the following features are present (for
|
||
more details see the documentation of cdlatex-mode):
|
||
* Environment templates can be inserted with `C-c {'.
|
||
|
||
* The <TAB> key will do template expansion if the cursor is inside a
|
||
LaTeX fragment(1). For example, <TAB> will expand `fr' to
|
||
`\frac{}{}' and position the cursor correctly inside the first
|
||
brace. Another <TAB> will get you into the second brace. Even
|
||
outside fragments, <TAB> will expand environment abbreviations at
|
||
the beginning of a line. For example, if you write `equ' at the
|
||
beginning of a line and press <TAB>, this abbreviation will be
|
||
expanded to an `equation' environment. To get a list of all
|
||
abbreviations, type `M-x cdlatex-command-help'.
|
||
|
||
* Pressing `_' and `^' inside a LaTeX fragment will insert these
|
||
characters together with a pair of braces. If you use <TAB> to
|
||
move out of the braces, and if the braces surround only a single
|
||
character or macro, they are removed again (depending on the
|
||
variable `cdlatex-simplify-sub-super-scripts').
|
||
|
||
* Pressing the backquote ``' followed by a character inserts math
|
||
macros, also outside LaTeX fragments. If you wait more than 1.5
|
||
seconds after the backquote, a help window will pop up.
|
||
|
||
* Pressing the normal quote `'' followed by another character
|
||
modifies the symbol before point with an accent or a font. If you
|
||
wait more than 1.5 seconds after the backquote, a help window will
|
||
pop up. Character modification will work only inside LaTeX
|
||
fragments, outside the quote is normal.
|
||
|
||
---------- Footnotes ----------
|
||
|
||
(1) Org-mode has a method to test if the cursor is inside such a
|
||
fragment, see the documentation of the function
|
||
`org-inside-LaTeX-fragment-p'.

10 Exporting
|
||
************
|
||
|
||
Org-mode documents can be exported into a variety of other formats. For
|
||
printing and sharing of notes, ASCII export produces a readable and
|
||
simple version of an Org-mode file. HTML export allows you to publish a
|
||
notes file on the web, while the XOXO format provides a solid base for
|
||
exchange with a broad range of other applications. To incorporate
|
||
entries with associated times like deadlines or appointments into a
|
||
desktop calendar program like iCal, Org-mode can also produce extracts
|
||
in the iCalendar format. Currently Org-mode only supports export, not
|
||
import of these different formats.
|
||
|
||
When exporting, Org-mode uses special conventions to enrich the
|
||
output produced. *Note Text interpretation::, for more details.

||
10.1 ASCII export
|
||
=================
|
||
|
||
ASCII export produces a simple and very readable version of an Org-mode
|
||
file.
|
||
|
||
`C-c C-e a'
|
||
Export as ASCII file. If there is an active region, only the
|
||
region will be exported. For an org file `myfile.org', the ASCII
|
||
file will be `myfile.txt'. The file will be overwritten without
|
||
warning.
|
||
|
||
`C-c C-e v a'
|
||
Export only the visible part of the document.
|
||
|
||
In the exported version, the first 3 outline levels will become
|
||
headlines, defining a general document structure. Additional levels
|
||
will be exported as itemized lists. If you want that transition to
|
||
occur at a different level, specify it with a prefix argument. For
|
||
example,
|
||
|
||
C-1 C-c C-e a
|
||
|
||
creates only top level headlines and does the rest as items. When
|
||
headlines are converted to items, the indentation of the text following
|
||
the headline is changed to fit nicely under the item. This is done with
|
||
the assumption that the first bodyline indicates the base indentation of
|
||
the body text. Any indentation larger than this is adjusted to preserve
|
||
the layout relative to the first line. Should there be lines with less
|
||
indentation than the first, these are left alone.

|
||
|
||
10.2 HTML export
|
||
================
|
||
|
||
Org-mode contains an HTML (XHTML 1.0 strict) exporter with extensive
|
||
HTML formatting, in ways similar to John Grubers _markdown_ language,
|
||
but with additional support for tables.
|
||
|
||
`C-c C-e h'
|
||
Export as HTML file `myfile.html'.
|
||
|
||
`C-c C-e b'
|
||
Export as HTML file and open it with a browser.
|
||
|
||
`C-c C-e v h'
|
||
|
||
`C-c C-e v b'
|
||
Export only the visible part of the document.
|
||
|
||
In the exported version, the first 3 outline levels will become
|
||
headlines, defining a general document structure. Additional levels
|
||
will be exported as itemized lists. If you want that transition to
|
||
occur at a different level, specify it with a prefix argument. For
|
||
example,
|
||
|
||
C-2 C-c C-e b
|
||
|
||
creates two levels of headings and does the rest as items.
|
||
|
||
If you want to include HTML tags which should be interpreted as such,
|
||
mark them with `@' as in `@<b>bold text@</b>'. Plain `<' and `>' are
|
||
always transformed to `<' and `>' in HTML export.
|
||
|
||
Internal links (*note Internal links::) will continue to work in HTML
|
||
files only if they match a dedicated `<<target>>'. Automatic links
|
||
created by radio targets (*note Radio targets::) will also work in the
|
||
HTML file. Links to external files will still work if the HTML file is
|
||
in the same directory as the Org-mode file. Links to other `.org'
|
||
files will be translated into HTML links under the assumption that an
|
||
HTML version also exists of the linked file. For information related to
|
||
linking files while publishing them to a publishing directory see *Note
|
||
Publishing links::.
|
||
|
||
You can also give style information for the exported file. The HTML
|
||
exporter assigns the following CSS classes to appropriate parts of the
|
||
document - your style specifications may change these:
|
||
.todo TODO keywords
|
||
.done the DONE keyword
|
||
.timestamp time stamp
|
||
.timestamp-kwd keyword associated with a time stamp, like SCHEDULED
|
||
.tag tag in a headline
|
||
.target target for links
|
||
|
||
The default style specification can be configured through the option
|
||
`org-export-html-style'. If you want to use a file-local style, you
|
||
may use file variables, best wrapped into a COMMENT section at the end
|
||
of the outline tree. For example:
|
||
|
||
* COMMENT HTML style specifications
|
||
|
||
# Local Variables:
|
||
# org-export-html-style: " <style type=\"text/css\">
|
||
# p {font-weight: normal; color: gray; }
|
||
# h1 {color: black; }
|
||
# </style>"
|
||
# End:
|
||
|
||
Remember to execute `M-x normal-mode' after changing this to make
|
||
the new style visible to Emacs. This command restarts org-mode for the
|
||
current buffer and forces Emacs to re-evaluate the local variables
|
||
section in the buffer.

||
10.3 XOXO export
|
||
================
|
||
|
||
Org-mode contains an exporter that produces XOXO-style output.
|
||
Currently, this exporter only handles the general outline structure and
|
||
does not interpret any additional Org-mode features.
|
||
|
||
`C-c C-e x'
|
||
Export as XOXO file `myfile.html'.
|
||
|
||
`C-c C-e v x'
|
||
Export only the visible part of the document.

|
||
10.4 iCalendar export
|
||
=====================
|
||
|
||
Some people like to use Org-mode for keeping track of projects, but
|
||
still prefer a standard calendar application for anniversaries and
|
||
appointments. In this case it can be useful to have deadlines and
|
||
other time-stamped items in Org-mode files show up in the calendar
|
||
application. Org-mode can export calendar information in the standard
|
||
iCalendar format.
|
||
|
||
`C-c C-e i'
|
||
Create iCalendar entries for the current file and store them in
|
||
the same directory, using a file extension `.ics'.
|
||
|
||
`C-c C-e I'
|
||
Like `C-c C-e i', but do this for all files in `org-agenda-files'.
|
||
For each of these files, a separate iCalendar file will be
|
||
written.
|
||
|
||
`C-c C-e c'
|
||
Create a single large iCalendar file from all files in
|
||
`org-agenda-files' and write it to the file given by
|
||
`org-combined-agenda-icalendar-file'.
|
||
|
||
How this calendar is best read and updated, depends on the
|
||
application you are using. For example, when using iCal under Apple
|
||
MacOS X, you could create a new calendar `OrgMode' (the default name
|
||
for the calendar created by `C-c C-e c', see the variables
|
||
`org-icalendar-combined-name' and
|
||
`org-combined-agenda-icalendar-file'). Then set Org-mode to overwrite
|
||
the corresponding file `~/Library/Calendars/OrgMode.ics'. You may even
|
||
use AppleScript to make iCal re-read the calendar files each time a new
|
||
version of `OrgMode.ics' is produced. Here is the setup needed for
|
||
this:
|
||
|
||
(setq org-combined-agenda-icalendar-file
|
||
"~/Library/Calendars/OrgMode.ics")
|
||
(add-hook 'org-after-save-iCalendar-file-hook
|
||
(lambda ()
|
||
(shell-command
|
||
"osascript -e 'tell application \"iCal\" to reload calendars'")))

10.5.1 Comment lines
|
||
--------------------
|
||
|
||
Lines starting with `#' in column zero are treated as comments and will
|
||
never be exported. Also entire subtrees starting with the word
|
||
`COMMENT' will never be exported. Finally, any text before the first
|
||
headline will not be exported either.
|

10.5.2 Enhancing text for export
|
||
--------------------------------
|
||
|
||
Some of the export backends of Org-mode allow for sophisticated text
|
||
formatting, this is true in particular for the HTML backend. Org-mode
|
||
has a number of typing conventions that allow to produce a richly
|
||
formatted output.
|
||
|
||
* Plain lists `-', `*' or `+' as bullet, or with `1.' or `2)' as
|
||
enumerator will be recognized and transformed if the backend
|
||
supports lists. See *Note Plain lists::.
|
||
|
||
* You can make words *bold*, /italic/, _underlined_, `=code=', and
|
||
`+strikethrough+'.
|
||
|
||
* Many TeX macros and entire LaTeX fragments are converted into HTML
|
||
entities or images (*note Embedded LaTeX::).
|
||
|
||
* Tables are transformed into native tables under the exporter, if
|
||
the export backend supports this. Data fields before the first
|
||
horizontal separator line will be formatted as table header fields.
|
||
|
||
* If a headline starts with the word `QUOTE', the text below the
|
||
headline will be typeset as fixed-width, to allow quoting of
|
||
computer codes etc. Lines starting with `:' are also typeset in
|
||
fixed-width font.
|
||
`C-c :'
|
||
Toggle fixed-width for entry (QUOTE) or region, see below.
|
||
|
||
* A double backslash _at the end of a line_ enforces a line break at
|
||
this position.
|
||
|
||
If these conversions conflict with your habits of typing ASCII text,
|
||
they can all be turned off with corresponding variables (see the
|
||
customization group `org-export-general', and the following section
|
||
which explains how to set export options with special lines in a buffer.

|
||
|
||
10.5.3 Export options
|
||
---------------------
|
||
|
||
The exporter recognizes special lines in the buffer which provide
|
||
additional information. These lines may be put anywhere in the file.
|
||
The whole set of lines can be inserted into the buffer with `C-c C-e
|
||
t'. For individual lines, a good way to make sure the keyword is
|
||
correct is to type `#+' and then use `M-<TAB>' completion (*note
|
||
Completion::).
|
||
|
||
`C-c C-e t'
|
||
Insert template with export options, see example below.
|
||
|
||
#+TITLE: the title to be shown (default is the buffer name)
|
||
#+AUTHOR: the author (default taken from `user-full-name')
|
||
#+EMAIL: his/her email address (default from `user-mail-address')
|
||
#+LANGUAGE: language for HTML, e.g. `en' (`org-export-default-language')
|
||
#+TEXT: Some descriptive text to be inserted at the beginning.
|
||
#+TEXT: Several lines may be given.
|
||
#+OPTIONS: H:2 num:t toc:t \n:nil @:t ::t |:t ^:t *:nil TeX:t LaTeX:t
|
||
|
||
The OPTIONS line is a compact form to specify export settings. Here
|
||
you can:
|
||
H: set the number of headline levels for export

||
num: turn on/off section-numbers

11 Publishing
|
||
*************
|
||
|
||
Org-mode includes(1) a publishing management system that allows you to
|
||
configure automatic HTML conversion of _projects_ composed of
|
||
interlinked org files. This system is called _org-publish_. You can
|
||
also configure org-publish to automatically upload your exported HTML
|
||
pages and related attachments, such as images and source code files, to
|
||
a web server. Org-publish turns org-mode into a web-site authoring
|
||
tool.
|
||
|
||
Org-publish has been contributed to Org-mode by David O'Toole.

11.1 Configuration
|
||
==================
|
||
|
||
Publishing needs significant configuration to specify files, destination
|
||
and many other properties of a project.
|
||
|
||
* Menu:
|
||
|
||
* Project alist:: The central configuration variable
|
||
* Sources and destinations:: From here to there
|
||
* Selecting files:: What files are part of the project?
|
||
* Publishing action:: Setting the function doing the publishing
|
||
* Publishing options:: Tweaking HTML export
|
||
* Publishing links:: Which links keep working after publishing?
|
||
* Project page index:: Publishing a list of project files
|
||
|
||
|
||

|
||
|
||
11.1.1 The variable `org-publish-project-alist'
|
||
-----------------------------------------------
|
||
|
||
Org-publish is configured almost entirely through setting the value of
|
||
one variable, called `org-publish-project-alist'. Each element of the
|
||
list configures one project, and may be in one of the two following
|
||
forms:
|
||
|
||
("project-name" :property value :property value ...)
|
||
|
||
or
|
||
|
||
("project-name" :components ("project-name" "project-name" ...))
|
||
|
||
In both cases, projects are configured by specifying property values.
|
||
A project defines the set of files that will be published, as well as
|
||
the publishing configuration to use when publishing those files. When
|
||
a project takes the second form listed above, the individual members of
|
||
the "components" property are taken to be components of the project,
|
||
which group together files requiring different publishing options. When
|
||
you publish such a "meta-project" all the components will also publish.
|
||
|
||
|
||

|
||
|
||
11.1.2 Sources and destinations for files
|
||
-----------------------------------------
|
||
|
||
Most properties are optional, but some should always be set. In
|
||
particular, org-publish needs to know where to look for source files,
|
||
and where to put published files.
|
||
|
||
`:base-directory' Directory containing publishing source files
|
||
`:publishing-directory'Directory (possibly remote) where output files
|
||
will be published.
|
||
`:preparation-function'Function called before starting publishing
|
||
process, for example to run `make' for updating
|
||
files to be published.
|
||
|
||
|
||
File: org, Node: Selecting files, Next: Publishing action, Prev: Sources and destinations, Up: Configuration
|
||
|
||
11.1.3 Selecting files
|
||
----------------------
|
||
|
||
By default, all files with extension `.org' in the base directory are
|
||
considered part of the project. This can be modified by setting the
|
||
properties
|
||
`:base-extension' Extension (without the dot!) of source files. This
|
||
actually is a regular expression.
|
||
`:exclude' Regular expression to match file names that should
|
||
not be published, even though they have been selected
|
||
on the basis of their extension.
|
||
`:include' List of files to be included regardless of
|
||
`:base-extension' and `:exclude'.

||

||

||
File: org, Node: Publishing action, Next: Publishing options, Prev: Selecting files, Up: Configuration
|
||
|
||
11.1.4 Publishing Action
|
||
------------------------
|
||
|
||
Publishing means that a file is copied to the destination directory and
|
||
possibly transformed in the process. The default transformation is to
|
||
export Org-mode files as HTML files, and this is done by the function
|
||
`org-publish-org-to-html' which calls the HTML exporter (*note HTML
|
||
export::). Other files like images only need to be copied to the
|
||
publishing destination. For non-Org-mode files, you need to specify
|
||
the publishing function.
|
||
|
||
`:publishing-function' Function executing the publication of a file.
|
||
This may also be a list of functions, which will
|
||
all be called in turn.
|
||
|
||
The function must accept two arguments: a property list containing at
|
||
least a `:publishing-directory' property, and the name of the file to
|
||
be published. It should take the specified file, make the necessary
|
||
transformation (if any) and place the result into the destination
|
||
folder. You can write your own publishing function, but `org-publish'
|
||
provides one for attachments (files that only need to be copied):
|
||
`org-publish-attachment'.

|
||
|
||
11.1.5 Options for the HTML exporter
|
||
------------------------------------
|
||
|
||
The property list can be used to set many export options for the HTML
|
||
exporter. In most cases, these properties correspond to user variables
|
||
in Org-mode. The table below lists these properties along with the
|
||
variable they belong to. See the documentation string for the
|
||
respective variable for details.
|
||
|
||

|
||
`:inline-images' `org-export-html-inline-images'
|
||
`:expand-quoted-html' `org-export-html-expand'
|
||
`:timestamp' `org-export-html-with-timestamp'
|
||

|
||
`:author' `user-full-name'
|
||
`:email' `user-mail-address'

||
When a property is given a value in org-publish-project-alist, its
|
||
setting overrides the value of the corresponding user variable (if any)
|
||
during publishing. options set within a file (*note Export options::),
|
||
however, override everything.

|
||
|
||
11.1.6 Links between published files
|
||
------------------------------------
|
||
|
||
To create a link from one Org-mode file to another, you would use
|
||
something like `[[file:foo.org][The foo]]' or simply `file:foo.org.'
|
||
(*note Hyperlinks::). Upon publishing this link becomes a link to
|
||
`foo.html'. In this way, you can interlink the pages of your "org web"
|
||
project and the links will work as expected when you publish them to
|
||
HTML.
|
||
|
||
You may also link to related files, such as images. Provided you are
|
||
careful with relative pathnames, and provided you have also configured
|
||
org-publish to upload the related files, these links will work too.
|
||
*Note Complex example:: for an example of this usage.
|
||
|
||
Sometime an Org-mode file to be published may contain links that are
|
||
only valid in your production environment, but not in the publishing
|
||
location. In this case, use the property
|
||
|
||
`:link-validation-function' Function to validate links
|
||
|
||
to define a function for checking link validity. This function must
|
||
accept two arguments, the file name and a directory relative to which
|
||
the file name is interpreted in the production environment. If this
|
||
function returns `nil', then the HTML generator will only insert a
|
||
description into the HTML file, but no link. One option for this
|
||
function is `org-publish-validate-link' which checks if the given file
|
||
is part of any project in `org-publish-project-alist'.

11.1.7 Project page index
|
||
-------------------------
|
||
|
||
The following properties may be used to control publishing of an index
|
||
of files or summary page for a given project.
|
||
|
||
`:auto-index' When non-nil, publish an index during
|
||
org-publish-current-project or org-publish-all.
|
||
`:index-filename' Filename for output of index. Defaults to `index.org'
|
||
(which becomes `index.html').
|
||
`:index-title' Title of index page. Defaults to name of file.
|
||
`:index-function' Plugin function to use for generation of index.
|
||
Defaults to `org-publish-org-index', which generates
|
||
a plain list of links to all files in the project.

Below we provide two example configurations. The first one is a simple
|
||
project publishing only a set of Org-mode files. The second example is
|
||
more complex, with a multi-component project.

11.2.1 Example: simple publishing configuration
|
||
-----------------------------------------------
|
||
|
||
This example publishes a set of Org-mode files to the `public_html'
|
||
directory on the local machine.
|
||
|
||
(setq org-publish-project-alist
|
||
'(("org"
|
||
:base-directory "~/org/"
|
||
:publishing-directory "~/public_html"
|
||
:section-numbers nil
|
||
:table-of-contents nil
|
||

File: org, Node: Complex example, Prev: Simple example, Up: Sample configuration
|
||
|
||
11.2.2 Example: complex publishing configuration
|
||
------------------------------------------------
|
||
|
||
This more complicated example publishes an entire website, including
|
||
org files converted to HTML, image files, emacs lisp source code, and
|
||
stylesheets. The publishing-directory is remote and private files are
|
||
excluded.
|
||
|
||
To ensure that links are preserved, care should be taken to replicate
|
||
your directory structure on the web server, and to use relative file
|
||
paths. For example, if your org files are kept in `~/org' and your
|
||
publishable images in `~/images', you'd link to an image with
|
||
file:../images/myimage.png
|
||
On the web server, the relative path to the image should be the
|
||
same. You can accomplish this by setting up an "images" folder in the
|
||
right place on the webserver, and publishing images to it.
|
||
|
||

11.3 Triggering publication
|
||
===========================
|
||
|
||
Once org-publish is properly configured, you can publish with the
|
||
following functions:
|
||
|
||
`C-c C-e c'
|
||
Prompt for a specific project and publish all files that belong to
|
||
it.
|
||
|
||
`C-c C-e p'
|
||
Publish the project containing the current file.
|
||
|
||
`C-c C-e f'
|
||
Publish only the current file.
|
||
|
||
`C-c C-e a'
|
||
Publish all projects.
|
||
|
||
Org uses timestamps to track when a file has changed. The above
|
||
functions normally only publish changed files. You can override this and
|
||
force publishing of all files by giving a prefix argument.

12.1 Completion
|
||
===============
|
||
|
||
Org-mode supports in-buffer completion. This type of completion does
|
||
not make use of the minibuffer. You simply type a few letters into the
|
||
buffer and use the key to complete text right there.
|
||
|
||
`M-<TAB>'
|
||
Complete word at point
|
||
* At the beginning of a headline, complete TODO keywords.
|
||
|
||
* After `\', complete TeX symbols supported by the exporter.
|
||
|
||
* After `*', complete headlines in the current buffer so that
|
||
they can be used in search links like `[[*find this
|
||
headline]]'.
|
||
|
||
* After `:', complete tags. The list of tags is taken from the
|
||
variable `org-tag-alist' (possibly set through the `#+TAGS'
|
||
in-buffer option, *note Setting tags::), or it is created
|
||
dynamically from all tags used in the current buffer.
|
||
|
||
* After `[', complete link abbreviations (*note Link
|
||
abbreviations::).
|
||
|
||
* After `#+', complete the special keywords like `TYP_TODO' or
|
||
`OPTIONS' which set file-specific options for Org-mode. When
|
||
the option keyword is already complete, pressing `M-<TAB>'
|
||
again will insert example settings for this keyword.
|
||
|
||
* In the line after `#+STARTUP: ', complete startup keywords,
|
||
i.e. valid keys for this line.
|
||
|
||
* Elsewhere, complete dictionary words using ispell.

12.2 Customization
|
||
==================
|
||
|
||
There are more than 100 variables that can be used to customize
|
||
Org-mode. For the sake of compactness of the manual, we are not
|
||
describing the variables here. A structured overview of customization
|
||
variables is available with `M-x org-customize'. Or select `Browse Org
|
||
Group' from the `Org->Customization' menu. Many settings can also be
|
||
activated on a per-file basis, by putting special lines into the buffer
|
||
(*note In-buffer settings::).

|
||
12.3 Summary of in-buffer settings
|
||
==================================
|
||
|
||
Org-mode uses special lines in the buffer to define settings on a
|
||
per-file basis. These lines start with a `#+' followed by a keyword, a
|
||
colon, and then individual words defining a setting. Several setting
|
||
words can be in the same line, but you can also have multiple lines for
|
||
the keyword. While these settings are described throughout the manual,
|
||
here is a summary. After changing any of those lines in the buffer,
|
||
press `C-c C-c' with the cursor still in the line to activate the
|
||
changes immediately. Otherwise they become effective only when the
|
||
file is visited again in a new Emacs session.
|
||
|
||
`#+STARTUP:'
|
||
This line sets options to be used at startup of org-mode, when an
|
||
Org-mode file is being visited. The first set of options deals
|
||
with the initial visibility of the outline tree. The
|
||
corresponding variable for global default settings is
|
||
`org-startup-folded', with a default value `t', which means
|
||
`overview'.
|
||
overview top-level headlines only
|
||
content all headlines
|
||
showall no folding at all, show everything
|
||
Then there are options for aligning tables upon visiting a file.
|
||
This is useful in files containing narrowed table columns. The
|
||
corresponding variable is `org-startup-align-all-tables', with a
|
||
default value `nil'.
|
||
align align all tables
|
||
noalign don't align tables on startup
|
||
Logging when a TODO item is marked DONE (variable `org-log-done')
|
||
can be configured using these options.
|
||
logging record a timestamp when an item is marked DONE
|
||
nologging don't record when items are marked DONE
|
||
Here are the options for hiding leading stars in outline headings.
|
||
The corresponding variables are `org-hide-leading-stars' and
|
||
`org-odd-levels-only', both with a default setting `nil' (meaning
|
||
`showstars' and `oddeven').
|
||
hidestars make all but one of the stars starting a headline invisible.
|
||
showstars show all stars starting a headline
|
||
odd allow only odd outline levels (1,3,...)
|
||
oddeven allow all outline levels
|
||
To turn on custom format overlayes over time stamps (variables
|
||
`org-put-time-stamp-overlays' and
|
||
`org-time-stamp-overlay-formats'), use
|
||
customtime overlay custom time format
|
||
|
||
`#+SEQ_TODO: #+TYP_TODO:'
|
||
These lines set the TODO keywords and their interpretation in the
|
||
current file. The corresponding variables are `org-todo-keywords'
|
||
and `org-todo-interpretation'.
|
||
|
||
`#+TAGS: TAG1(c1) TAG2(c2)'
|
||
These lines (several such lines are allowed) specify the legal
|
||
tags in this file, and (potentially) the corresponding _fast tag
|
||
selection_ keys. The corresponding variable is `org-tag-alist'.
|
||
|
||
`#+LINK: linkword replace'
|
||
These lines (several are allowed) specify link abbreviations.
|
||
*Note Link abbreviations::. The corresponding variable is
|
||
`org-link-abbrev-alist'.
|
||
|
||
`#+CATEGORY:'
|
||
This line sets the category for the agenda file. The category
|
||
applies for all subsequent lines until the next `#+CATEGORY' line,
|
||
or the end of the file.
|
||
|
||
`#+TBLFM:'
|
||
This line contains the formulas for the table directly above the
|
||
line.
|
||
|
||
`#+TITLE:, #+AUTHOR:, #+EMAIL:, #+LANGUAGE:, #+TEXT:, #+OPTIONS:'
|
||
These lines provide settings for exporting files. For more
|
||
details see *Note Export options::.

12.4 The very busy C-c C-c key
|
||
==============================
|
||
|
||
The key `C-c C-c' has many purposes in org-mode, which are all
|
||
mentioned scattered throughout this manual. One specific function of
|
||
this key is to add _tags_ to a headline (*note Tags::). In many other
|
||
circumstances it means something like _Hey Org-mode, look here and
|
||
update according to what you see here_. Here is a summary of what this
|
||
means in different contexts.
|
||
|
||
- If there are highlights in the buffer from the creation of a sparse
|
||
tree, or from clock display, remove these highlights.
|
||
|
||
- If the cursor is in one of the special `#+KEYWORD' lines, this
|
||
triggers scanning the buffer for these lines and updating the
|
||
information.
|
||
|
||
- If the cursor is inside a table, realign the table. This command
|
||
works even if the automatic table editor has been turned off.
|
||
|
||
- If the cursor is on a `#+TBLFM' line, re-apply the formulas to the
|
||
entire table.
|
||
|
||
- If the cursor is inside a table created by the `table.el' package,
|
||
activate that table.
|
||
|
||
- If the current buffer is a remember buffer, close the note and
|
||
file it. With a prefix argument, file it, without further
|
||
interaction, to the default location.
|
||
|
||
- If the cursor is on a `<<<target>>>', update radio targets and
|
||
corresponding links in this buffer.
|
||
|
||
- If the cursor is in a plain list item with a checkbox, toggle the
|
||
status of the checkbox.
|
||
|
||
- If the cursor is on a numbered item in a plain list, renumber the
|
||
ordered list.

||
12.5 A cleaner outline view
|
||
===========================
|
||
|
||
Some people find it noisy and distracting that the Org-mode headlines
|
||
are starting with a potentially large number of stars. For example the
|
||
tree from *Note Headlines:::
|
||
|
||
* Top level headline
|
||
** Second level
|
||
*** 3rd level
|
||
some text
|
||
*** 3rd level
|
||
more text
|
||
* Another top level headline
|
||
|
||
Unfortunately this is deeply ingrained into the code of Org-mode and
|
||
cannot be easily changed. You can, however, modify the display in such
|
||
a way that all leading stars become invisible and the outline more easy
|
||
to read. To do this, customize the variable `org-hide-leading-stars'
|
||
like this:
|
||
|
||
(setq org-hide-leading-stars t)
|
||
|
||
or change this on a per-file basis with one of the lines (anywhere in
|
||
the buffer)
|
||
|
||
#+STARTUP: showstars
|
||
#+STARTUP: hidestars
|
||
|
||
Press `C-c C-c' with the cursor in a `STARTUP' line to activate the
|
||
modifications.
|
||
|
||
With stars hidden, the tree becomes:
|
||
|
||
* Top level headline
|
||
* Second level
|
||
* 3rd level
|
||
some text
|
||
* 3rd level
|
||
more text
|
||
* Another top level headline
|
||
|
||
Note that the leading stars are not truly replaced by whitespace, they
|
||
are only fontified with the face `org-hide' that uses the background
|
||
color as font color. If are are not using either white or black
|
||
background, you may have to customize this face to get the wanted
|
||
effect. Another possibility is to set this font such that the extra
|
||
stars are almost invisible, for example using the color `grey90' on a
|
||
white background.
|
||
|
||
Things become cleaner still if you skip all the even levels and use
|
||
only odd levels 1, 3, 5..., effectively adding two stars to go from one
|
||
outline level to the next:
|
||
|
||
* Top level headline
|
||
* Second level
|
||
* 3rd level
|
||
some text
|
||
* 3rd level
|
||
more text
|
||
* Another top level headline
|
||
|
||
In order to make the structure editing and export commands handle this
|
||
convention correctly, use
|
||
|
||
(setq org-odd-levels-only t)
|
||
|
||
or set this on a per-file basis with one of the following lines (don't
|
||
forget to press `C-c C-c' with the cursor in the startup line to
|
||
activate changes immediately).
|
||
|
||
#+STARTUP: odd
|
||
#+STARTUP: oddeven
|
||
|
||
You can convert an Org-mode file from single-star-per-level to the
|
||
double-star-per-level convention with `M-x org-convert-to-odd-levels
|
||
RET' in that file. The reverse operation is `M-x
|
||
org-convert-to-oddeven-levels'.

12.6 Using org-mode on a tty
|
||
============================
|
||
|
||
Org-mode uses a number of keys that are not accessible on a tty. This
|
||
applies to most special keys like cursor keys, <TAB> and <RET>, when
|
||
these are combined with modifier keys like <Meta> and/or <Shift>.
|
||
Org-mode uses these bindings because it needs to provide keys for a
|
||
large number of commands, and because these keys appeared particularly
|
||
easy to remember. In order to still be able to access the core
|
||
functionality of Org-mode on a tty, alternative bindings are provided.
|
||
Here is a complete list of these bindings, which are obviously more
|
||
cumbersome to use. Note that sometimes a work-around can be better.
|
||
For example changing a time stamp is really only fun with `S-<cursor>'
|
||
keys. On a tty you would rather use `C-c .' to re-insert the
|
||
timestamp.
|
||
|
||
Default Alternative 1 Alternative 2
|
||
`S-<TAB>' `C-u <TAB>'
|
||
`M-<left>' `C-c C-x l' `<Esc> <left>'
|
||
`M-S-<left>'`C-c C-x L'
|
||
`M-<right>' `C-c C-x r' `<Esc>
|
||
<right>'
|
||
`M-S-<right>'`C-c C-x R'
|
||
`M-<up>' `C-c C-x u' `<Esc> <up>'
|
||
`M-S-<up>' `C-c C-x U'
|
||
`M-<down>' `C-c C-x d' `<Esc> <down>'
|
||
`M-S-<down>'`C-c C-x D'
|
||
`S-<RET>' `C-c C-x c'
|
||
`M-<RET>' `C-c C-x m' `<Esc> <RET>'
|
||
`M-S-<RET>' `C-c C-x M'
|
||
`S-<left>' `C-c C-x
|
||
<left>'
|
||
`S-<right>' `C-c C-x

12.7 Interaction with other packages
|
||
====================================
|
||
|
||
Org-mode lives in the world of GNU Emacs and interacts in various ways
|
||
with other code out there.

||
12.7.1 Packages that Org-mode cooperates with
|
||
---------------------------------------------
|
||
|
||
`calc.el' by Dave Gillespie
|
||
Org-mode uses the calc package for implementing spreadsheet
|
||
functionality in its tables (*note Table calculations::).
|
||
Org-modes checks for the availability of calc by looking for the
|
||
function `calc-eval' which should be autoloaded in your setup if
|
||
calc has been installed properly. As of Emacs 22, calc is part of
|
||
the Emacs distribution. Another possibility for interaction
|
||
between the two packages is using calc for embedded calculations.
|
||
*Note Embedded Mode: (calc)Embedded Mode.
|
||
|
||
`constants.el' by Carsten Dominik
|
||
In a table formula (*note Table calculations::), it is possible to
|
||
use names for natural constants or units. Instead of defining
|
||
your own constants in the variable `org-table-formula-constants',
|
||
install the `constants' package which defines a large number of
|
||
constants and units, and lets you use unit prefixes like `M' for
|
||
`Mega' etc. You will need version 2.0 of this package, available
|
||
at `http://www.astro.uva.nl/~dominik/Tools'. Org-mode checks for
|
||
the function `constants-get', which has to be autoloaded in your
|
||
setup. See the installation instructions in the file
|
||
`constants.el'.
|
||
|
||
`cdlatex.el' by Carsten Dominik
|
||
Org-mode can make use of the cdlatex package to efficiently enter
|
||
LaTeX fragments into Org-mode files. See *Note CDLaTeX mode::.
|
||
|
||
`remember.el' by John Wiegley
|
||
Org mode cooperates with remember, see *Note Remember::.
|
||
`Remember.el' is not part of Emacs, find it on the web.
|
||
|
||
`table.el' by Takaaki Ota
|
||
Org mode cooperates with table.el, see *Note table.el::.
|
||
`table.el' is part of Emacs 22.

||

||

|
||
|
||
12.7.2 Packages that lead to conflicts with Org-mode
|
||
----------------------------------------------------
|
||
|
||
`allout.el' by Ken Manheimer
|
||
Startup of Org-mode may fail with the error message
|
||
`(wrong-type-argument keymapp nil)' when there is an outdated
|
||
version `allout.el' on the load path, for example the version
|
||
distributed with Emacs 21.x. Upgrade to Emacs 22 and this problem
|
||
will disappear. If for some reason you cannot do this, make sure
|
||
that org.el is loaded _before_ `allout.el', for example by putting
|
||
`(require 'org)' early enough into your `.emacs' file.
|
||
|
||
`CUA.el' by Kim. F. Storm
|
||
Keybindings in Org-mode conflict with the `S-<cursor>' keys used
|
||
by CUA-mode (as well as pc-select-mode and s-region-mode) to
|
||
select and extend the region. If you want to use one of these
|
||
packages along with Org-mode, configure the variable
|
||
`org-CUA-compatible'. When set, Org-mode will move the following
|
||
keybindings in org-mode files, and in the agenda buffer (but not
|
||
during date selection).
|
||
|
||
S-UP -> M-p S-DOWN -> M-n
|
||
S-LEFT -> M-- S-RIGHT -> M-+
|
||
S-RET -> C-S-RET
|
||
|
||
Yes, these are unfortunately more difficult to remember. If you
|
||
want to have other replacement keys, look at the variable
|
||
`org-disputed-keys'.
|
||
|
||
`windmove.el' by Hovav Shacham
|
||
Also this package uses the `S-<cursor>' keys, so everything written
|
||
in the paragraph above about CUA mode also applies here.

12.8 Bugs
|
||
=========
|
||
|
||
Here is a list of things that should work differently, but which I have
|
||
found too hard to fix.
|
||
|
||
* If a table field starts with a link, and if the corresponding table
|
||
column is narrowed (*note Narrow columns::) to a width too small to
|
||
display the link, the field would look entirely empty even though
|
||
it is not. To prevent this, Org-mode throws an error. The
|
||
work-around is to make the column wide enough to fit the link, or
|
||
to add some text (at least 2 characters) before the link in the
|
||
same field.
|
||
|
||
* Narrowing table columns does not work on XEmacs, because the
|
||
`format' function does not transport text properties.
|
||
|
||
* Text in an entry protected with the `QUOTE' keyword should not
|
||
autowrap.
|
||
|
||
* When the application called by `C-c C-o' to open a file link fails
|
||
(for example because the application does not exist or refuses to
|
||
open the file), it does so silently. No error message is
|
||
displayed.
|
||
|
||
* The remote-editing commands in the agenda buffer cannot be undone
|
||
with `undo' called from within the agenda buffer. But you can go
|
||
to the corresponding buffer (using <TAB> or <RET> and execute
|
||
`undo' there.
|
||
|
||
* Recalculating a table line applies the formulas from left to right.
|
||
If a formula uses _calculated_ fields further down the row,
|
||
multiple recalculation may be needed to get all fields consistent.
|
||
|
||
* A single letter cannot be made bold, for example `*a*'.
|
||
|
||
* The exporters work well, but could be made more efficient.

A.1 Third-party extensions for Org-mode
|
||
=======================================
|
||
|
||
The following extensions for Org-mode have been written by other people:
|
||
|
||
`org-mouse.el' by Piotr Zielinski
|
||
This package implements extended mouse functionality for Org-mode.
|
||
It allows you to cycle visibility and to edit the document
|
||
structure with the mouse. Best of all, it provides a
|
||
context-sensitive menu on <mouse-3> that changes depending on the
|
||
context of a mouse-click. `org-mouse.el' is freely available at
|
||
`http://www.cl.cam.ac.uk/~pz215/files/org-mouse.el'.
|
||
|
||
`org-publish.el' by David O'Toole
|
||
This package provides facilities for publishing related sets of
|
||
Org-mode files together with linked files like images as a
|
||
webpages. It is highly configurable and can be used for other
|
||
publishing purposes as well. As of Org-mode version 4.30,
|
||
`org-publish.el' is part of the Org-mode distribution. It is not
|
||
yet part of Emacs, however, a delay caused by the preparations for
|
||
the 22.1 release. In the mean time, `org-publish.el' can be
|
||
downloaded from David's site:
|
||
`http://dto.freeshell.org/e/org-publish.el'.
|
||
|
||
`org-blog.el' by David O'Toole
|
||
A blogging plug-in for `org-publish.el'.
|
||
`http://dto.freeshell.org/notebook/OrgMode.html'.
|
||
|
||
`org-blogging.el' by Bastien Guerry
|
||
Publish Org-mode files as blogs.
|
||
`http://www.cognition.ens.fr/~guerry/org-blogging.html'.

||
|
||
A.2 Dynamic blocks
|
||
==================
|
||
|
||
Org-mode documents can contain _dynamic blocks_. These are specially
|
||
marked regions that are updated by some user-written function. A good
|
||
example for such a block is the clock table inserted by the command
|
||
`C-c C-x C-r' (*note Clocking work time::).
|
||
|
||
Dynamic block are enclosed by a BEGIN-END structure that assigns a
|
||
name to the block and can also specify parameters for the function
|
||
producing the content of the block.
|
||
|
||
#+BEGIN: myblock :parameter1 value1 :parameter2 value2 ...
|
||
|
||
#+END:
|
||
|
||
Dynamic blocks are updated with the following commands
|
||
|
||
`C-c C-x C-u'
|
||
Update dynamic block at point.
|
||
|
||
`C-u C-c C-x C-u'
|
||
Update all dynamic blocks in the current file.
|
||
|
||
Updating a dynamic block means to remove all the text between BEGIN
|
||
and END, parse the BEGIN line for parameters and then call the specific
|
||
writer function for this block to insert the new content. For a block
|
||
with name `myblock', the writer function is `org-dblock-write:myblock'
|
||
with as only parameter a property list with the parameters given in the
|
||
begin line. Here is a trivial example of a block that keeps track of
|
||
when the block update function was last run:
|
||
|
||
#+BEGIN: block-update-time :format "on %m/%d/%Y at %H:%M"
|
||
|
||
#+END:
|
||
|
||
The corresponding block writer function could look like this:
|
||
|
||
(defun org-dblock-write:block-update-time (params)
|
||
(let ((fmt (or (plist-get params :format) "%d. %m. %Y")))
|
||
(insert "Last block update at: "
|
||
(format-time-string fmt (current-time)))))
|
||
|
||
If you want to make sure that all dynamic blocks are always
|
||
up-to-date, you could add the function `org-update-all-dblocks' to a
|
||
hook, for example `before-save-hook'. `org-update-all-dblocks' is
|
||
written in a way that is does nothing in buffers that are not in
|
||
Org-mode.

Appendix B History and Acknowledgments
|
||
**************************************
|
||
|
||
Org-mode was borne in 2003, out of frustration over the user interface
|
||
of the Emacs outline-mode. All I wanted was to make working with an
|
||
outline tree possible without having to remember more than 10 commands
|
||
just for hiding and unhiding parts of the outline tree, and to allow to
|
||
restructure a tree easily. Visibility cycling and structure editing
|
||
were originally implemented in the package `outline-magic.el', but
|
||
quickly moved to the more general `org.el'. TODO entries, basic time
|
||
stamps, and table support were added next, and highlight the two main
|
||
goals that Org-mode still has today: To create a new, outline-based,
|
||
plain text mode with innovative and intuitive editing features, and to
|
||
incorporate project planning functionality directly into a notes file.
|
||
|
||
Since the first release, hundreds of emails to me or on
|
||
`emacs-orgmode@gnu.org' have provided a constant stream of bug reports,
|
||
feedback, new ideas, and sometimes even patches and add-on code. Many
|
||
thanks to everyone who has helped to improve this package. I am trying
|
||
to keep here a list of the people who had significant influence in
|
||
shaping one or more aspects of Org-mode. The list may not be complete,
|
||
if I have forgotten someone, please accept my apologies and let me know.

details. I later looked at John's code, however, and learned from

and only a description is shown, and (ii) popping up a calendar to
|
||
select a date.
