;;; Commentary:
;;
;; 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.
;;
;; Installation and Activation
;; ---------------------------
;; See the corresponding sections in the manual at
;;
;;   http://orgmode.org/org.html#Installation
;;
;; Documentation
;; -------------
;; The documentation of Org-mode can be found in the TeXInfo file.  The
;; distribution also contains a PDF version of it.  At the homepage of
;; Org-mode, you can read the same text online as HTML.  There is also an
;; excellent reference card made by Philip Rooke.  This card can be found
;; in the etc/ directory of Emacs 22.

(defcustom org-support-shift-select nil
  "Non-nil means make shift-cursor commands select text when possible.

In Emacs 23, when `shift-select-mode' is on, shifted cursor keys start
selecting a region, or enlarge thusly regions started in this way.
In Org-mode, in special contexts, these same keys are used for other
purposes, important enough to compete with shift selection.  Org tries
to balance these needs by supporting `shift-select-mode' outside these
special contexts, under control of this variable.

The default of this variable is nil, to avoid confusing behavior.  Shifted
cursor keys will then execute Org commands in the following contexts:
- on a headline, changing TODO state (left/right) and priority (up/down)
- on a time stamp, changing the time
- in a plain list item, changing the bullet type
- in a property definition line, switching between allowed values
- in the BEGIN line of a clock table (changing the time block).
Outside these contexts, the commands will throw an error.

When this variable is t and the cursor is not in a special context,
Org-mode will support shift-selection for making and enlarging regions.
To make this more effective, the bullet cycling will no longer happen
anywhere in an item line, but only if the cursor is exactly on the bullet.

If you set this variable to the symbol `always', then the keys
will not be special in headlines, property lines, and item lines, to make
shift selection work there as well.  If this is what you want, you can
use the following alternative commands: `C-c C-t' and `C-c ,' to
change TODO state and priority, `C-u C-u C-c C-t' can be used to switch
TODO sets, `C-c -' to cycle item bullet types, and properties can be
edited by hand or in column view.

However, when the cursor is on a timestamp, shift-cursor commands
will still edit the time stamp - this is just too good to give up.

XEmacs user should have this variable set to nil, because shift-select-mode
is Emacs 23 only."

               Remote files most likely should be visited through Emacs
               because external applications cannot handle such paths.
`auto-mode'    Matches files that are matched by any entry in `auto-mode-alist',
               so all files Emacs knows how to handle.  Using this with
               command `emacs' will open most files in Emacs.  Beware that this
               will also open html files inside Emacs, unless you add
               (\"html\" . default) to the list as well.
 t             Default for files not matched by any of the other options.
 `system'      The system command to open files, like `open' on Windows
               and Mac OS X, and mailcap under GNU/Linux.  This is the command
               that will be selected if you call `C-c C-o' with a double
               `C-u C-u' prefix.

Possible values for the command are:
 `emacs'       The file will be visited by the current Emacs process.
 `default'     Use the default application for this file type, which is the
               association for t in the list, most likely in the system-specific
               part.
               This can be used to overrule an unwanted setting in the
               system-specific variable.
 `system'      Use the system command for opening files, like \"open\".
               This command is specified by the entry whose car is `system'.
               Most likely, the system-specific version of this variable
               does define this command, but you can overrule/replace it
               here.
 string        A command to be executed by a shell; %s will be replaced
               by the path to the file.
 sexp          A Lisp form which will be evaluated.  The file path will
               be available in the Lisp variable `file'.
For more examples, see the system specific constants
`org-file-apps-defaults-macosx'

  "List of TODO entry keyword sequences and their interpretation.
\\<org-mode-map>This is a list of sequences.

Each sequence starts with a symbol, either `sequence' or `type',
indicating if the keywords should be interpreted as a sequence of
action steps, or as different types of TODO items.  The first
keywords are states requiring action - these states will select a headline
for inclusion into the global TODO list Org-mode produces.  If one of
the \"keywords\" is the vertical bat \"|\" the remaining keywords
signify that no further action is necessary.  If \"|\" is not found,
the last keyword is treated as the only DONE state of the sequence.

The command \\[org-todo] cycles an entry through these states, and one
additional state where no keyword is present.  For details about this
cycling, see the manual.

TODO keywords and interpretation can also be set on a per-file basis with
the special #+SEQ_TODO and #+TYP_TODO lines.

Each keyword can optionally specify a character for fast state selection
\(in combination with the variable `org-use-fast-todo-selection')
and specifiers for state change logging, using the same syntax
that is used in the \"#+TODO:\" lines.  For example, \"WAIT(w)\" says
that the WAIT state can be selected with the \"w\" key. \"WAIT(w!)\"
indicates to record a time stamp each time this state is selected.

Each keyword may also specify if a timestamp or a note should be
recorded when entering or leaving the state, by adding additional
characters in the parenthesis after the keyword.  This looks like this:
\"WAIT(w@/!)\".  \"@\" means to add a note (with time), \"!\" means to
record only the time of the state change.  With X and Y being either
\"@\" or \"!\", \"X/Y\" means use X when entering the state, and use
Y when leaving the state if and only if the *target* state does not
define X.  You may omit any of the fast-selection key or X or /Y,
so WAIT(w@), WAIT(w/@) and WAIT(@/@) are all valid.

For backward compatibility, this variable may also be just a list
of keywords - in this case the interpretation (sequence or type) will be
taken from the (otherwise obsolete) variable `org-todo-interpretation'."

  "The location where subtrees should be archived.

The value of this variable is a string, consisting of two parts,
separated by a double-colon.  The first part is a filename and
the second part is a headline.

When the filename is omitted, archiving happens in the same file.
%s in the filename will be replaced by the current file
name (without the directory part).  Archiving to a different file
is useful to keep archived entries from contributing to the
Org-mode Agenda.

The archived entries will be filed as subtrees of the specified
headline.  When the headline is omitted, the subtrees are simply
filed away at the end of the file, as top-level entries.  Also in
the heading you can use %s to represent the file name, this can be
useful when using the same archive for a number of different files.

Here are a few examples:
\"%s_archive::\"
	If the current file is Projects.org, archive in file
	Projects.org_archive, as top-level trees.  This is the default.

\"::* Archived Tasks\"
	Archive in the current file, under the top-level headline
	\"* Archived Tasks\".

\"~/org/archive.org::\"
	Archive in file ~/org/archive.org (absolute path), as top-level trees.

\"~/org/archive.org::From %s\"
	Archive in file ~/org/archive.org (absolute path), under headlines
        \"From FILENAME\" where file name is the current file name.

\"basement::** Finished Tasks\"
	Archive in file ./basement (relative path), as level 3 trees
	below the level 2 heading \"** Finished Tasks\".

You may set this option on a per-file basis by adding to the buffer a
line like

#+ARCHIVE: basement::** Finished Tasks

in the entry.  If such a property is found in an entry, or anywhere up

  "Outline-based notes management and organizer, alias
\"Carsten's outline-mode for keeping track of everything.\"

Org-mode develops organizational tasks around a NOTES file which
contains information about projects as plain text.  Org-mode is
implemented on top of outline-mode, which is ideal to keep the content
of large files well structured.  It supports ToDo items, deadlines and
time stamps, which magically appear in the diary listing of the Emacs
calendar.  Tables are easily created with a built-in table editor.
Plain text URL-like links connect to websites, emails (VM), Usenet
messages (Gnus), BBDB entries, and any files related to the project.
For printing and sharing of notes, an Org-mode file (or a part of it)
can be exported as a structured ASCII or HTML file.

The following commands are available:

\\{org-mode-map}"

  ;; Get rid of Outline menus, they are not needed

  "TAB-action and visibility cycling for Org-mode.

This is the command invoked in Org-mode by the TAB key.  Its main purpose
is outline visibility cycling, but it also invokes other actions
in special contexts.

- When this function is called with a prefix argument, rotate the entire
  buffer through 3 states (global cycling)
  1. OVERVIEW: Show only top-level headlines.
  2. CONTENTS: Show all headlines of all levels, but no body text.
  3. SHOW ALL: Show everything.
  When called with two `C-u C-u' prefixes, switch to the startup visibility,
  determined by the variable `org-startup-folded', and by any VISIBILITY
  properties in the buffer.
  When called with three `C-u C-u C-u' prefixed, show the entire buffer,
  including any drawers.

- When inside a table, re-align the table and move to the next field.

- When point is at the beginning of a headline, rotate the subtree started
  by this line through 3 different states (local cycling)
  1. FOLDED:   Only the main headline is shown.
  2. CHILDREN: The main headline and the direct children are shown.
               From this state, you can move to one of the children
               and zoom in further.
  3. SUBTREE:  Show the entire subtree, including body text.
  If there is no subtree, switch directly from CHILDREN to FOLDED.

- When point is at the beginning of an empty headline and the variable
  `org-cycle-level-after-item/entry-creation' is set, cycle the level
  of the headline by demoting and promoting it to likely levels.  This
  speeds up creation document structure by presing TAB once or several
  times right after creating a new headline.

- When there is a numeric prefix, go up to a heading with level ARG, do
  a `show-subtree' and return to the previous cursor position.  If ARG
  is negative, go up that many levels.

- When point is not at the beginning of a headline, execute the global
  binding for TAB, which is re-indenting the line.  See the option
  `org-cycle-emulate-tab' for details.

- Special case: if point is at the beginning of the buffer and there is
  no headline in line 1, this function will act as if called with prefix arg.
  But only if also the variable `org-cycle-global-at-bob' is t."

Else, if the cursor is before the first entry, sort the top-level items.

If the cursor is at the first item in a plain list, the list items will be
sorted.

Sorting can be alphabetically, numerically, by date/time as given by
a time stamp, by a property or by priority.

The command prompts for the sorting type unless it has been given to the
function through the SORTING-TYPE argument, which needs to a character,
\(?n ?N ?a ?A ?t ?T ?s ?S ?d ?D ?p ?P ?r ?R ?f ?F).  Here is the
precise meaning of each character:

n   Numerically, by converting the beginning of the entry/item to a number.
a   Alphabetically, ignoring the TODO keyword and the priority, if any.
t   By date/time, either the first active time stamp in the entry, or, if
    none exist, by the first inactive one.
    In items, only the first line will be checked.
s   By the scheduled date/time.
d   By deadline date/time.
c   By creation time, which is assumed to be the first inactive time stamp
    at the beginning of a line.
p   By priority according to the cookie.
r   By the value of a property.

Capital letters will reverse the sort order.

If the SORTING-TYPE is ?f or ?F, then GETKEY-FUNC specifies a function to be
called with point at the beginning of the record.  It must return either
a string or a number that should serve as the sorting key for that record.

Comparing entries ignores case by default.  However, with an optional argument

;;; The orgstruct minor mode

;; Define a minor mode which can be used in other modes in order to
;; integrate the org-mode structure editing commands.

;; This is really a hack, because the org-mode structure commands use
;; keys which normally belong to the major mode.  Here is how it
;; works: The minor mode defines all the keys necessary to operate the
;; structure commands, but wraps the commands into a function which
;; tests if the cursor is currently at a headline or a plain list
;; item.  If that is the case, the structure command is used,
;; temporarily setting many Org-mode variables like regular
;; expressions for filling etc.  However, when any of those keys is
;; used at a different location, function uses `key-binding' to look
;; up if the key has an associated command in another currently active
;; keymap (minor modes, major mode, global), and executes that
;; command.  There might be problems if any of the keys is otherwise
;; used as a prefix key.

;; Another challenge is that the key binding for TAB can be tab or \C-i,
;; likewise the binding for RET can be return or \C-m.  Orgtbl-mode
;; addresses this by checking explicitly for both bindings.

Completion can be used to insert any of the link protocol prefixes like

The history can be used to select a link previously stored with
`org-store-link'.  When the empty string is entered (i.e. if you just
press RET at the prompt), the link defaults to the most recently
stored link.  As SPC triggers completion in the minibuffer, you need to
use M-SPC or C-q SPC to force the insertion of a space character.

You will also be prompted for a description, and if one is given, it will
be displayed in the buffer instead of the link.

If there is already a link at point, this command will allow you to edit link
and description parts.

With a \\[universal-argument] prefix, prompts for a file to link to. The file name can
be selected using completion. The path to the file will be relative to the
current directory if the file is in the current directory or a subdirectory.
Otherwise, the link will be the absolute path as completed in the minibuffer
\(i.e. normally ~/path/to/file).  You can configure this behavior using the
option `org-link-file-path-type'.

With two \\[universal-argument] prefixes, enforce an absolute path even if the file is in
the current directory or below.

With three \\[universal-argument] prefixes, negate the meaning of
`org-keep-stored-link-after-insertion'.

If `org-make-link-description-function' is non-nil, this function will be
called with the link target, and the result will be the default
link description.

If the LINK-LOCATION parameter is non-nil, this value will be
used as the link location instead of reading one interactively."

which see.

A function in this hook may also use `setq' to set the variable
`description' to provide a suggestion for the descriptive text to
be used for this link when it gets inserted into an Org-mode
buffer with \\[org-insert-link].")

(defvar org-execute-file-search-functions nil
  "List of functions to execute a file search triggered by a link.

Functions added to this hook must accept a single argument, the
search string that was part of the file link, the part after the
double colon.  The function must first check if it would like to
handle this search, for example by checking the major-mode or the
file extension.  If it decides not to handle this search, it
should just return nil to give other functions a chance.  If it
does handle the search, it must return a non-nil value to keep
other functions from trying.

Each function can access the current prefix argument through the
variable `current-prefix-argument'.  Note that a single prefix is
used to force opening a link in Emacs, so it may be good to only
use a numeric or double prefix to guide the search function.

In case this is needed, a function in this hook can also restore
the window configuration before `org-open-at-point' was called using:

    (set-window-configuration org-window-config-before-follow-link)")

Depending on `org-reverse-note-order', the new subitem will either be the

below it are allowed.

not actually move anything.
With a double prefix `C-u C-u', go to the location where the last refiling
operation has put the subtree.
With a prefix argument of `2', refile to the running clock.

The state of an item is given by a keyword at the start of the heading,

The different keywords are specified in the variable `org-todo-keywords'.
By default the available states are \"TODO\" and \"DONE\".
So for this example: when the item starts with TODO, it is changed to DONE.
When it starts with DONE, the DONE is removed.  And when neither TODO nor
DONE are present, add TODO at the beginning of the heading.

With C-u prefix arg, use completion to determine the new state.
With numeric prefix arg, switch to that state.
With a double C-u prefix, switch to the next set of TODO keywords (nextset).
With a triple C-u prefix, circumvent any state blocking.

For calling through lisp, arg is also interpreted in the following way:
'none             -> empty state

  "Call FUNC at each headline selected by MATCH in SCOPE.

FUNC is a function or a lisp form.  The function will be called without
arguments, with the cursor positioned at the beginning of the headline.
The return values of all calls to the function will be collected and
returned as a list.

The call to FUNC will be wrapped into a save-excursion form, so FUNC
does not need to preserve point.  After evaluation, the cursor will be
moved to the end of the line (presumably of the headline of the
processed entry) and search continues from there.  Under some
circumstances, this may not produce the wanted results.  For example,
if you have removed (e.g. archived) the current (sub)tree it could
mean that the next entry will be skipped entirely.  In such cases, you
can specify the position from where search should continue by making
FUNC set the variable `org-map-continue-from' to the desired buffer
position.

MATCH is a tags/property/todo match as it is used in the agenda tags view.
Only headlines that are matched by this query will be considered during
the iteration.  When MATCH is nil or t, all headlines will be
visited by the iteration.

SCOPE determines the scope of this command.  It can be any of:

nil     The current buffer, respecting the restriction if any
tree    The subtree started with the entry at point
file    The current buffer, without restriction
file-with-archives
        The current buffer, and any archives associated with it
agenda  All agenda files
agenda-with-archives
        All agenda files with any archive files associated with them
\(file1 file2 ...)
        If this is a list, all files in the list will be scanned

The remaining args are treated as settings for the skipping facilities of
the scanner.  The following items can be given here:

  archive    skip trees with the archive tag.
  comment    skip trees with the COMMENT keyword
  function or Emacs Lisp form:
             will be used as value for `org-agenda-skip-function', so whenever
             the function returns t, FUNC will not be called for that
             entry and search will continue from the point where the
             function leaves it.

If your function needs to retrieve the tags including inherited tags
at the *current* entry, you can use the value of the variable
`org-scanner-tags' which will be much faster than getting the value
with `org-get-tags-at'.  If your function gets properties with
`org-entry-properties' at the *current* entry, bind `org-trust-scanner-tags'
to t around the call to `org-entry-properties' to get the same speedup.
Note that if your function moves around to retrieve tags and properties at
a *different* entry, you cannot use these techniques."

  "Read a date, possibly a time, and make things smooth for the user.
The prompt will suggest to enter an ISO date, but you can also enter anything
which will at least partially be understood by `parse-time-string'.
Unrecognized parts of the date will default to the current day, month, year,
hour and minute.  If this command is called to replace a timestamp at point,
of to enter the second timestamp of a range, the default time is taken from the
existing stamp.  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)
  etc.

Furthermore you can specify a relative date by giving, as the *first* thing
in the input:  a plus/minus sign, a number and a letter [dwmy] to indicate
change in days weeks, months, years.
With a single plus or minus, the date is relative to today.  With a double
plus or minus, it is relative to the date in DEFAULT-TIME.  E.g.
  +4d           --> four days from today
  +4            --> same as above
  +2w           --> two weeks from today
  ++5           --> five days from default date

The function understands only English month and weekday abbreviations,
but this can be configured with the variables `parse-time-months' and
`parse-time-weekdays'.

While prompting, a calendar is popped up - you can also select the
date with the mouse (button 1).  The calendar shows a period of three
months.  To scroll it to other months, use the keys `>' and `<'.
If you don't like the calendar, turn it off with
       \(setq org-read-date-popup-calendar nil)

With optional argument TO-TIME, the date will immediately be converted
to an internal time.
With an optional argument WITH-TIME, the prompt will suggest to also
insert a time.  Note that when WITH-TIME is not set, you can still
enter a time, and this function will inform the calling routine about
this change.  The calling routine may then choose to change the format
used to insert the time stamp into the buffer to include the time.
With optional argument FROM-STRING, read from this string instead from
the user.  PROMPT can overwrite the default prompt.  DEFAULT-TIME is
the time/date that is used for everything that is not specified by the
user."

- If the cursor is in a headline, prompt for tags and insert them

- If the cursor is in one of the special #+KEYWORD lines, this

- 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 at a footnote reference or definition, jump to
  the corresponding definition or references, respectively.

- If the cursor is a the beginning of a dynamic block, update it.

- 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 note and file
  it.  A prefix argument of 1 files to the default location
  without further interaction.  A prefix argument of 2 files to
  the currently clocking task.

- If the cursor is on a <<<target>>>, update radio targets and corresponding

    fit into the local outline tree structure, which means that the level
    will be adjusted so that it becomes the smaller one of the two
    *visible* surrounding headings.

Any prefix to this command will cause `yank' to be called directly with
no special treatment.  In particular, a simple `C-u' prefix will just
plainly yank the text as it is.
