;;; 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://staff.science.uva.nl/~dominik/Tools/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.

In this case, an entry looks like this:

  (key desc (cmd1 cmd2 ...) general-options file)

desc   A description string to be displayed in the dispatcher menu.
cmd    An agenda command, similar to the above.  However, tree commands

  "Format specifications for the prefix of items in the agenda views.
An alist with four entries, for the different agenda types.  The keys to the
sublists are `agenda', `timeline', `todo', and `tags'.  The values
are format strings.
This format works similar to a printf format, with the following meaning:

  %c   the category of the item, \"Diary\" for entries from the diary, or
       as given by the CATEGORY keyword or derived from the file name.
  %T   the *last* tag of the item.  Last because inherited tags come
       first in the list.
  %t   the time-of-day specification if one applies to the entry, in the
       format HH:MM
  %s   Scheduling/Deadline information, a short string

All specifiers work basically like the standard `%s' of printf, but may
contain two additional characters:  A question mark just after the `%' and
a whitespace/punctuation character just before the final letter.

If the first character after `%' is a question mark, the entire field
will only be included if the corresponding value applies to the
current entry.  This is useful for fields which should have fixed
width when present, but zero width when absent.  For example,
\"%?-12t\" will result in a 12 character time field if a time of the
day is specified, but will completely disappear in entries which do
not contain a time.

If there is punctuation or whitespace character just before the final
format letter, this character will be appended to the field value if
the value is not empty.  For example, the format \"%-12:c\" leads to
\"Diary: \" if the category is \"Diary\".  If the category were be
empty, no additional colon would be interted.

The default value of this option is \"  %-12:c%?-12t% s\", meaning:
- Indent the line with two space characters
- Give the category in a 12 chars wide field, padded with whitespace on
  the right (because of `-').  Append a colon if there is a category
  (because of `:').
- If there is a time-of-day, put it into a 12 chars wide field.  If no
  time, don't put in an empty field, just skip it (because of '?').
- Finally, put the scheduling information and append a whitespace.

As another example, if you don't want the time-of-day of entries in
the prefix, you could use:

  (setq org-agenda-prefix-format \"  %-11:c% s\")

post         Chars allowed as postmatch.  End of line will be allowed too.
border       The chars *forbidden* as border characters.
body-regexp  A regexp like \".\" to match a body character.  Don't use
             non-shy groups here, and don't allow newline here.
newline      The maximum number of newlines allowed in an emphasis exp.

  "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

;;; 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.

This is useful if you'd like to spread the contents of a field over several

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.  Generally, this makes the table more compact.  A prefix ARG may be
used to change the number of desired lines.  For example, `C-2 \\[org-table-wrap]'
formats the selected text to two lines.  If the region was longer than two
lines, the remaining lines remain empty.  A negative prefix argument reduces
the current number of lines by that amount.  The wrapped text is pasted back
into the table.  If you formatted it to more lines than it was before, fields
further down in the table get overwritten - so you might need to make space in
the table first.

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

  "Replace the table field value at the cursor by the result of a calculation.

This function makes use of Dave Gillespie's Calc package, in my view the
most exciting program ever written for GNU Emacs.  So you need to have Calc
installed in order to use this function.

In a table, this command replaces the value in the current field with the
result of a formula.  It also installs the formula as the \"current\" column
formula, by storing it in a special line below the table.  When called
with a `C-u' prefix, the current field must ba a named field, and the
formula is installed as valid in only this specific field.

When called with two `C-u' prefixes, insert the active equation
for the field back into the current field, so that it can be
edited there.  This is useful in order to use \\[org-table-show-reference]
to check the referenced fields.

When called, the command first prompts for a formula, which is read in
the minibuffer.  Previously entered formulas are available through the
history list, and the last used formula is offered as a default.
These stored formulas are adapted correctly when moving, inserting, or
deleting columns with the corresponding commands.

The formula can be any algebraic expression understood by the Calc package.
For details, see the Org-mode manual.

This function can also be called from Lisp programs and offers
additional arguments: EQUATION can be the formula to apply.  If this
argument is given, the user will not be prompted.  SUPPRESS-ALIGN is
used to speed-up recursive calls by by-passing unnecessary aligns.
SUPPRESS-CONST suppresses the interpretation of constants in the
formula, assuming that this has been done already outside the function.
SUPPRESS-STORE means the formula should not be stored, either because
it is already stored, or because it is a modified equation that should
not overwrite the stored one."

;;; The orgtbl minor mode

;; Define a minor mode which can be used in other modes in order to
;; integrate the org-mode table editor.

;; This is really a hack, because the org-mode table editor uses several
;; keys which normally belong to the major mode, for example the TAB and
;; RET keys.  Here is how it works: The minor mode defines all the keys
;; necessary to operate the table editor, but wraps the commands into a
;; function which tests if the cursor is currently inside a table.  If that
;; is the case, the table editor command is executed.  However, when any of
;; those keys is used outside a table, the 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 used by the table editor 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.

;; The optimized version (see variable `orgtbl-optimized') takes over
;; all keys which are bound to `self-insert-command' in the *global map*.
;; Some modes bind other commands to simple characters, for example
;; AUCTeX binds the double quote to `Tex-insert-quote'.  With orgtbl-mode
;; active, this binding is ignored inside tables and replaced with a
;; modified self-insert.

This generic routine can be used for many standard cases.
TABLE is a list, each entry either the symbol `hline' for a horizontal
separator line, or a list of fields for that line.
PARAMS is a property list of parameters that can influence the conversion.
For the generic converter, some parameters are obligatory:  You need to
specify either :lfmt, or all of (:lstart :lend :sep).  If you do not use
:splice, you must have :tstart and :tend.

Valid parameters are

:tstart     String to start the table.  Ignored when :splice is t.
:tend       String to end the table.  Ignored when :splice is t.

:splice     When set to t, return only table body lines, don't wrap
            them into :tstart and :tend.  Default is nil.

:hline      String to be inserted on horizontal separation lines.
            May be nil to ignore hlines.

:lstart     String to start a new table line.
:lend       String to end a table line
:sep        Separator between two fields
:lfmt       Format for entire line, with enough %s to capture all fields.
            If this is present, :lstart, :lend, and :sep are ignored.
:fmt        A format to be used to wrap the field, should contain
            %s for the original field value.  For example, to wrap
            everything in dollars, you could use :fmt \"$%s$\".
            This may also be a property list with column numbers and
            formats. for example :fmt (2 \"$%s$\" 4 \"%s%%\")

:hlstart :hlend :hlsep :hlfmt :hfmt
            Same as above, specific for the header lines in the table.
            All lines before the first hline are treated as header.
            If any of these is not present, the data line value is used.

:efmt       Use this format to print numbers with exponentials.
            The format should have %s twice for inserting mantissa
            and exponent, for example \"%s\\\\times10^{%s}\".  This
            may also be a property list with column numbers and
            formats.  :fmt will still be applied after :efmt.

In addition to this, the parameters :skip and :skipcols are always handled
directly by `orgtbl-send-table'.  See manual."

Completion can be used to select a link previously stored with

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).

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

These functions are called in turn with point at the location to
which the link should point.

A function in the hook should first test if it would like to
handle this file type, for example by checking the major-mode or
the file extension.  If it decides not to handle this file, it
should just return nil to give other functions a chance.  If it
does handle the file, it must return the search string to be used
when following the link.  The search string will be part of the
file link, given after a double colon, and `org-open-at-point'
will automatically search for it.  If special measures must be
taken to make the search successful, another function should be
added to the companion hook `org-execute-file-search-functions',
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

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:

  "Store stuff from remember.el into an org file.
First prompts for an org file.  If the user just presses return, the value
of `org-default-notes-file' is used.
Then the command offers the headings tree of the selected file in order to
file the text at a specific location.
You can either immediately press RET to get the note appended to the
file, or you can use vertical cursor motion and visibility cycling (TAB) to
find a better place.  Then press RET or <left> or <right> in insert the note.

Key      Cursor position   Note gets inserted
-----------------------------------------------------------------------------
RET      buffer-start      as level 2 heading at end of file
RET      on headline       as sublevel of the heading at cursor
RET      no heading        at cursor position, level taken from context.
			   Or use prefix arg to specify level manually.
<left>   on headline       as same level, before current heading
<right>  on headline       as same level, after current heading

So the fastest way to store the note is to press RET RET to append it to
the default file.  This way your current train of thought is not
interrupted, in accordance with the principles of remember.el.  But with
little extra effort, you can push it directly to the correct location.

Before being stored away, 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
\(i.e. after the stars).

See also the variable `org-reverse-note-order'."

  feb 15        --> currentyear-02-15
  sep 12 9      --> 2009-09-12

  22 sept 0:34  --> currentyear-09-22 0:34
  12            --> currentyear-currentmonth-12
  Fri           --> nearest Friday (today or later)
  +4            --> four days from today (only if +N is the only thing given)
  etc.
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-popup-calendar-for-date-prompt 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."

  "Return diary information from org-files.
This function can be used in a \"sexp\" diary entry in the Emacs calendar.
It accesses org files and extracts information from those files to be
listed in the diary.  The function accepts arguments specifying what
items should be listed.  The following arguments are allowed:

   :timestamp    List the headlines of items containing a date stamp or
		 date range matching the selected date.  Deadlines will
		 also be listed, on the expiration day.

   :sexp         FIXME

   :deadline     List any deadlines past due, or due within
		 `org-deadline-warning-days'.  The listing occurs only
		 in the diary for *today*, not at any other date.  If
		 an entry is marked DONE, it is no longer listed.

   :scheduled    List all items which are scheduled for the given date.
		 The diary for *today* also contains items which were
		 scheduled earlier and are not yet marked DONE.

   :todo         List all TODO items from the org-file.  This may be a
		 long list - so this is not turned on by default.
		 Like deadlines, these entries only show up in the
		 diary for *today*, not at any other date.

The call in the diary file should look like this:

   &%%(org-diary) ~/path/to/some/orgfile.org

Use a separate line for each org file to check.  Or, if you omit the file name,
all files listed in `org-agenda-files' will be checked automatically:

   &%%(org-diary)

If you don't give any arguments (as in the example above), the default
arguments (:deadline :scheduled :timestamp :sexp) are used.
So the example above may also be written as

   &%%(org-diary :deadline :timestamp :sexp :scheduled)

The function expects the lisp variables `entry' and `date' to be provided
by the caller, because this is how the calendar works.  Don't use this
function from a program - use `org-agenda-get-day-entries' instead."
