Therefore, only ;; session mode is supported. In practice, non-session code blocks are ;; handled equally well by the session mode. However, only a single ;; session is supported. Consequently, the :session header argument is ;; ignored. ;; ;; The Org-babel header argument :results is interpreted as ;; follows. :results output requires the respective code block to be ;; an Oz statement and :results value requires an Oz ;; expression. Currently, results are only supported for expressions ;; (i.e. the result of :results output is always nil). ;; ;; Expression evaluation happens synchronously. Therefore there is an ;; additional header argument :wait-time , which specifies the ;; maximum time to wait for the result of a given expression. nil ;; means to wait as long as it takes to get a result (potentially wait ;; forever). ;; ;; NOTE: Currently the copyright of this file may not be in a state to ;; permit inclusion as core software into Emacs or Org-mode. ;;; Requirements: ;; - Mozart Programming System, the implementation of the Oz ;; programming language (http://www.mozart-oz.org/), which includes ;; the major mode mozart for editing Oz programs. ;; ;; - StartOzServer.oz which is located in the contrib/scripts ;; directory of the Org-mode repository ;;; TODO: ;; - Decide: set communication to \\switch -threadedqueries? ;; ;; - Only start Oz compiler when required, e.g., load Org-babel only when needed? ;; ;; - Avoid synchronous evaluation to avoid blocking Emacs (complex ;; Strasheela programs can take long to find a result..). In order ;; to cleanly map code blocks to their associated results (which can ;; arrive then in any order) I could use IDs ;; (e.g. integers). However, how do I do concurrency in Emacs Lisp, ;; and how can I define org-babel-execute:oz concurrently. ;; ;; - Expressions are rarely used in Oz at the top-level, and using ;; them in documentation and Literate Programs will cause ;; confusion. Idea: hide expression from reader and instead show ;; them statement (e.g., MIDI output statement) and then include ;; result in Org file. Implementation: for expressions (:results ;; value) support an additional header argument that takes arbitrary ;; Oz code. This code is not seen by the reader, but will be used ;; for the actual expression at the end. Alternative: feed all ;; relevant code as statement (:results output), then add expression ;; as extra code block which outputs, e.g., file name (so the file ;; name must be accessible by global var), but the code of this ;; extra codeblock is not seen. Hm, in that case it might be even ;; more easy to manually add this link to the Org file. ;; (require 'ob) ;;; major mode for editing Oz programs (require 'mozart) ;; ;; Interface to communicate with Oz. ;; (1) For statements without any results: oz-send-string ;; (2) For expressions with a single result: oz-send-string-expression ;; (defined in org-babel-oz-ResultsValue.el) ;; ;; oz-send-string-expression implements an additional very direct ;; communication between Org-babel and the Oz compiler. Communication ;; with the Oz server works already without this code via the function ;; oz-send-string from mozart.el.in, but this function does not get ;; back any results from Oz to Emacs. The following code creates a ;; socket for sending code to the OPI compiler and results are ;; returned by the same socket. On the Oz side, a socket is opened and ;; conected to the compiler of the OPI (via oz-send-string). On the ;; Emacs side, a connection to this socket is created for feeding code ;; and receiving results. This additional communication channel to the ;; OPI compiler ensures that results are returned cleanly (e.g., only ;; the result of the sent code is returned, no parsing or any ;; processing of *Oz Emulator* is required). ;; ;; There is no buffer, nor sentinel involved. Oz code is send ;; directly, and results from Oz are send back, but Emacs Lisp ;; requires a filter function for processing results.

When called with a prefix argument, move to the first invoice report after point and update it. For information about various settings for the invoice report, see the `org-dblock-write:invoice' function documentation. An invoice report is created by reading a heading tree and collecting information from various properties. It is assumed that all invoices start at a second level heading, but this can be configured using the `org-invoice-default-level' variable. Here is an example, where all invoices fall under the first-level heading Invoices: * Invoices ** Client Foo (Jan 01 - Jan 15) *** [2008-01-01 Tue] Built New Server for Production *** [2008-01-02 Wed] Meeting with Team to Design New System ** Client Bar (Jan 01 - Jan 15) *** [2008-01-01 Tue] Searched for Widgets on Google *** [2008-01-02 Wed] Billed You for Taking a Nap In this layout, invoices begin at level two, and invoice items (tasks) are at level three. You'll notice that each level three heading starts with an inactive timestamp. The timestamp can actually go anywhere you want, either in the heading, or in the text under the heading. But you must have a timestamp somewhere so that the invoice report can group your items by date. Properties are used to collect various bits of information for the invoice. All properties can be set on the invoice item headings, or anywhere in the tree. The invoice report will scan up the tree looking for each of the properties. Properties used: CLOCKSUM: You can use the Org clock-in and clock-out commands to create a CLOCKSUM property. Also see WORK. WORK: An alternative to the CLOCKSUM property. This property should contain the amount of work that went into this invoice item formatted as HH:MM (e.g. 01:30). RATE: Used to calculate the total price for an invoice item. Should be the price per hour that you charge (e.g. 45.00). It might make more sense to place this property higher in the hierarchy than on the invoice item headings. Using this information, a report is generated that details the items grouped by days. For each day you will be able to see the total number of hours worked, the total price, and the items worked on. You can place the invoice report anywhere in the tree you want. I place mine under a third-level heading like so: * Invoices ** An Invoice Header *** [2008-11-25 Tue] An Invoice Item *** Invoice Report #+BEGIN: invoice #+END:" (interactive "P") (let ((report (org-invoice-in-report-p))) (when (and (not report) jump) (when (re-search-forward "^#\\+BEGIN:[ \t]+invoice" nil t) (org-show-entry) (beginning-of-line) (setq report (point)))) (if report (goto-char report) (org-create-dblock (list :name "invoice"))) (org-update-dblock))) (provide 'org-invoice) org-mode-8.2.4/contrib/lisp/org-panel.el0000644000175000017500000005434212260050771016167 0ustar sebseb;;; org-panel.el --- Simple routines for us with bad memory ;; ;; Author: Lennart Borgman (lennart O borgman A gmail O com) ;; Created: Thu Nov 15 15:35:03 2007 ;; Version: 0.21 ;; Lxast-Updated: Wed Nov 21 03:06:03 2007 (3600 +0100) ;; URL: ;; Keywords: ;; Compatibility: ;; ;; Features that might be required by this library: ;; ;; `easymenu', `font-lock', `noutline', `org', `outline', `syntax', ;; `time-date'. ;; ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ;; ;;; Commentary: ;; ;; This defines a kind of control panel for `org-mode'.

;;; Commentary:
;;
;; This modules allows to include output from various commands into an
;; Org-mode buffer, both for live display, and for export.
;; This technique has been copied from emacs-wiki and Emacs Muse, and
;; we try to make it work here in a way as similar as possible to
;; Muse, so that people who move between both worlds don't need to learn
;; new syntax.
;;
;; Basically it works like this:
;;
;;    (concat "aaa" "bbb")
;;
;; will display "aaabbb" in the buffer and export like that as well.
;; The leading lisp tag will also accept the attributes "markup" and
;; "lang", to specify how the text should be formatted during export.
;; For example,
;;
;;     .... 
;;
;; will format the result of the lisp form as if it was lisp source
;; code.  Internally, it will wrap the text into a
;;
;;    #+begin_src emacs-lisp
;;    #+end_src
;;
;; structure so that the right things happen when the exporter is running.
;;
;; By default, only the  tag is turned on, but you can configure
;; the variable `org-eval-interpreters' to add more interpreters like
;; `perl', `python', or the `shell'.
;;
;; You can edit the code snippets with "C-c '" (org-edit-src-code).
;;
;; Please note that this mechanism is potentially dangerous, because it
;; executes code that you don't even see.  This gives you great power,
;; but also enough rope to hang yourself.  And, it gives your friends
;; who send you Org files plenty of opportunity for good and bad jokes.
;; This is also why this module is not turned on by default, but only
;; available as a contributed package.

;;; Commentary:

;; `org-git-link.el' defines two new link types. The `git' link
;; type is meant to be used in the typical scenario and mimics the
;; `file' link syntax as closely as possible. The `gitbare' link
;; type exists mostly for debugging reasons, but also allows e.g.
;; linking to files in a bare git repository for the experts.

;; * User friendy form
;;   [[git:/path/to/file::searchstring]]

;;   This form is the familiar from normal org file links
;;   including search options. However, its use is
;;   restricted to files in a working directory and does not
;;   handle bare repositories on purpose (see the bare form for
;;   that).

;;   The search string references a commit (a tree-ish in Git
;;   terminology). The two most useful types of search strings are

;;   - A symbolic ref name, usually a branch or tag name (e.g.
;;     master or nobelprize).
;;   - A ref followed by the suffix @ with a date specification
;;     enclosed in a brace pair (e.g. {yesterday}, {1 month 2
;;     weeks 3 days 1 hour 1 second ago} or {1979-02-26 18:30:00})
;;     to specify the value of the ref at a prior point in time
;;
;; * Bare git form
;;   [[gitbare:$GIT_DIR::$OBJECT]]
;;
;;    This is the more bare metal version, which gives the user most
;;    control. It directly translates to the git command
;;    git --no-pager --git-dir=$GIT_DIR show $OBJECT
;;    Using this version one can also view files from a bare git
;;    repository. For detailed information on how to specify an
;;    object, see the man page of `git-rev-parse' (section
;;    SPECIFYING REVISIONS). A specific blob (file) can be
;;    specified by a suffix clolon (:) followed by a path.

;;
;;; Commentary:
;;
;; WARNING: This file is just a PROOF OF CONCEPT, not a supported part
;;          of Org-mode.
;;
;; This is an example implementation of TODO dependencies in Org-mode.
;; It uses the new hooks in version 5.13 of Org-mode,
;; `org-trigger-hook' and `org-blocker-hook'.
;;
;; It implements the following:
;;
;; Triggering
;; ----------
;;
;; 1) If an entry contains a TRIGGER property that contains the string
;;    "chain-siblings(KEYWORD)", then switching that entry to DONE does
;;    do the following:
;;    - The sibling following this entry switched to todo-state KEYWORD.
;;    - The sibling also gets a TRIGGER property "chain-sibling(KEYWORD)",
;;      property, to make sure that, when *it* is DONE, the chain will
;;      continue.
;;
;; 2) If an entry contains a TRIGGER property that contains the string
;;    "chain-siblings-scheduled", then switching that entry to DONE does
;;    the following actions, similarly to "chain-siblings(KEYWORD)":
;;    - The sibling receives the same scheduled time as the entry
;;      marked as DONE (or, in the case, in which there is no scheduled
;;      time, the sibling does not get any either).
;;    - The sibling also gets the same TRIGGER property
;;      "chain-siblings-scheduled", so the chain can continue.
;;
;; 3) If the TRIGGER property contains the string
;;    "chain-find-next(KEYWORD[,OPTIONS])", then switching that entry
;;    to DONE do the following:
;;    - All siblings are of the entry are collected into a temporary
;;      list and then filtered and sorted according to OPTIONS
;;    - The first sibling on the list is changed into KEYWORD state
;;    - The sibling also gets the same TRIGGER property
;;      "chain-find-next", so the chain can continue.
;;
;;    OPTIONS should be a comma separated string without spaces, and
;;    can contain following options:
;;
;;    - from-top      the candidate list is all of the siblings in
;;                    the current subtree
;;
;;    - from-bottom   candidate list are all siblings from bottom up
;;
;;    - from-current  candidate list are all siblings from current item
;;                    until end of subtree, then wrapped around from
;;                    first sibling
;;
;;    - no-wrap       candidate list are siblings from current one down
;;
;;    - todo-only     Only consider siblings that have a todo keyword
;;    -
;;    - todo-and-done-only
;;                    Same as above but also include done items.
;;
;;    - priority-up   sort by highest priority
;;    - priority-down sort by lowest priority
;;    - effort-up     sort by highest effort
;;    - effort-down   sort by lowest effort
;;
;;    Default OPTIONS are from-top
;;
;;
;; 4) If the TRIGGER property contains any other words like
;;    XYZ(KEYWORD), these are treated as entry id's with keywords.  That
;;    means Org-mode will search for an entry with the ID property XYZ
;;    and switch that entry to KEYWORD as well.
;;
;; Blocking
;; --------
;;
;; 1) If an entry contains a BLOCKER property that contains the word
;;    "previous-sibling", the sibling above the current entry is
;;    checked when you try to mark it DONE.  If it is still in a TODO
;;    state, the current state change is blocked.
;;
;; 2) If the BLOCKER property contains any other words, these are
;;    treated as entry id's.  That means Org-mode will search for an
;;    entry with the ID property exactly equal to this word.  If any
;;    of these entries is not yet marked DONE, the current state change
;;    will be blocked.
;;
;; 3) Whenever a state change is blocked, an org-mark is pushed, so that
;;    you can find the offending entry with `C-c &'.
;;
;;; Example:
;;
;; When trying this example, make sure that the settings for TODO keywords
;; have been activated, i.e. include the following line and press C-c C-c
;; on the line before working with the example:
;;
;; #+TYP_TODO: TODO NEXT | DONE
;;
;; * TODO Win a million in Las Vegas
;;   The "third" TODO (see above) cannot become a TODO without this money.
;;
;;   :PROPERTIES:
;;     :ID: I-cannot-do-it-without-money
;;   :END:
;;
;; * Do this by doing a chain of TODO's
;; ** NEXT This is the first in this chain
;;    :PROPERTIES:
;;      :TRIGGER: chain-siblings(NEXT)
;;    :END:
;;
;; ** This is the second in this chain
;;
;; ** This is the third in this chain
;;    :PROPERTIES:
;;      :BLOCKER: I-cannot-do-it-without-money
;;    :END:
;;
;; ** This is the forth in this chain
;;    When this is DONE, we will also trigger entry XYZ-is-my-id
;;   :PROPERTIES:
;;     :TRIGGER: XYZ-is-my-id(TODO)
;;   :END:
;;
;; ** This is the fifth in this chain
;;
;; * Start writing report
;;   :PROPERTIES:
;;     :ID: XYZ-is-my-id
;;   :END:

;;; Commentary:
;;
;; This modules implements some of the formatting tags available in
;; Emacs Muse.  This is not a way if adding new functionality, but just
;; a different way to write some formatting directives.  The advantage is
;; that files written in this way can be read by Muse reasonably well,
;; and that this provides an alternative way of writing formatting
;; directives in Org, a way that some might find more pleasant to type
;; and look at that the Org's #+BEGIN..#+END notation.

;; The goal of this development is to make it easier for people to
;; move between both worlds as they see fit for different tasks.

;; The following muse tags will be translated during export into their
;; native Org equivalents:
;;
;;   

;;        Needs to be at the end of a line.  Will be translated to "\\".
;;
;;   
;;        Needs to be on a line by itself, similarly the  tag.
;;        Will be translated into Org's #+BEGIN_EXAMPLE construct.
;;
;;   
;;        Needs to be on a line by itself, similarly the  tag.
;;        Will be translated into Org's #+BEGIN_QUOTE construct.
;;
;;   
;;        Needs to be on a line by itself, similarly the  tag.
;;        Will be translated into Org's #+BEGIN_COMMENT construct.
;;
;;   
;;        Needs to be on a line by itself, similarly the  tag.
;;        Will be translated into Org's #+BEGIN_VERSE construct.
;;
;;   
;;        This gets translated into "[TABLE-OF-CONTENTS]".  It will not
;;        trigger the production of a table of contents - that is done
;;        in Org with the "#+OPTIONS: toc:t" setting.  But it will define
;;        the location where the TOC will be placed.
;;
;;       ;; only latex, html, and docbook supported
;;        in Org.
;;        Needs to be on a line by itself, similarly the  tag.
;;
;;   
;;        Needs to be on a line by itself, similarly the  tag.
;;        Will be translated into Org's BEGIN_SRC construct.
;;
;;   
;;        Needs to be on a line by itself.
;;        Will be translated into Org's #+INCLUDE construct.
;;
;; The lisp/perl/ruby/python tags can be implemented using the
;; `org-eval.el' module, which see.

;;; Commentary:

;; This library implements an S5 Presentation back-end for the Org
;; generic exporter.

;; Installation
;; ------------
;; Get the s5 scripts from
;;    http://meyerweb.com/eric/tools/s5/
;; (Note that the default s5 version is set for using the alpha, 1.2a2.
;; Copy the ui dir to somewhere reachable from your published presentation
;; The default (`org-s5-ui-url') is set to "ui" (e.g., in the
;; same directory as the html file).

;; Usage
;; -----
;; Follow the general instructions at the above website. To generate
;; incremental builds, you can set the HTML_CONTAINER_CLASS on an
;; object to "incremental" to make it build. If you want an outline to
;; build, set the :INCREMENTAL property on the parent headline.

;; To test it, run:
;;
;;   M-x org-s5-export-as-html
;;
;; in an Org mode buffer.  See ox.el and ox-html.el for more details
;; on how this exporter works.

;;; Commentary:
;; Org-Velocity.el is an interface for Org inspired by the minimalist
;; notetaking program Notational Velocity. The idea is to let you
;; amass and access brief notes on many subjects with minimal fuss.
;; Each note is an entry in an ordinary Org file.

;; Org-Velocity can be used in two ways: when called outside Org, to
;; store and access notes in a designated bucket file; or, when called
;; inside Org, as a method for navigating any Org file. (Setting the
;; option `org-velocity-always-use-bucket' disables navigation inside
;; Org files by default, although you can still force this behavior by
;; calling `org-velocity-read' with an argument.)

;; Org-Velocity prompts for search terms in the minibuffer. A list of
;; headings of entries whose text matches your search is updated as
;; you type; you can end the search and visit an entry at any time by
;; clicking on its heading.

;; RET displays the results. If there are no matches, Org-Velocity
;; offers to create a new entry with your search string as its
;; heading. If there are matches, it displays a list of results where
;; the heading of each matching entry is hinted with a number or
;; letter; clicking a result, or typing the matching hint, opens the
;; entry for editing in an indirect buffer. 0 forces a new entry; RET
;; reopens the search for editing.

;; You can customize every step in this process, including the search
;; method, completion for search terms, and templates for creating new
;; entries; M-x customize-group RET org-velocity RET to see all the
;; options.

;; Thanks to Richard Riley, Carsten Dominik, Bastien Guerry, and Jeff
;; Horn for their suggestions.

  "Convert the orgtbl-mode TABLE to SQL insert statements.
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.

Names and strings are modified slightly by default.  Single-ticks
are doubled as per SQL's standard mechanism.  Backslashes and
dollar signs are deleted.  And tildes are changed to spaces.
These modifications were chosed for use with TeX.  See
ORGTBL-SQL-STRIP-AND-QUOTE.

Supports all parameters from ORGTBL-TO-GENERIC.  New to this function
are:

:sqlname   The name of the database table; defaults to the name of the
           target region.

:nowebname If not nil, used as a wrapping noweb fragment name.

The most important parameters of ORGTBL-TO-GENERIC for SQL are:

:splice    When set to t, return only insert statements, don't wrap
           them in a transaction.  Default is nil.

:tstart, :tend
           The strings used to begin and commit the transaction.

:hfmt      A function that gathers the quoted header names into a
           dynamically scoped variable HDRLIST.  Probably should
           not be changed by the user.

The general parameters :skip and :skipcols have already been applied when
this function is called."

;;; Commentary:

;; This package converts the buffer text and the associated
;; decorations to HTML.  Mail to  to discuss
;; features and additions.  All suggestions are more than welcome.

;; To use it, just switch to the buffer you want HTML-ized and type
;; `M-x htmlize-buffer'.  You will be switched to a new buffer that
;; contains the resulting HTML code.  You can edit and inspect this
;; buffer, or you can just save it with C-x C-w.  `M-x htmlize-file'
;; will find a file, fontify it, and save the HTML version in
;; FILE.html, without any additional intervention.  `M-x
;; htmlize-many-files' allows you to htmlize any number of files in
;; the same manner.  `M-x htmlize-many-files-dired' does the same for
;; files marked in a dired buffer.

;; htmlize supports three types of HTML output, selected by setting
;; `htmlize-output-type': `css', `inline-css', and `font'.  In `css'
;; mode, htmlize uses cascading style sheets to specify colors; it
;; generates classes that correspond to Emacs faces and uses ... to color parts of text.  In this mode, the
;; produced HTML is valid under the 4.01 strict DTD, as confirmed by
;; the W3C validator.  `inline-css' is like `css', except the CSS is
;; put directly in the STYLE attribute of the SPAN element, making it
;; possible to paste the generated HTML into existing HTML documents.
;; In `font' mode, htmlize uses ... to
;; colorize HTML, which is not standard-compliant, but works better in
;; older browsers.  `css' mode is the default.

;; You can also use htmlize from your Emacs Lisp code.  When called
;; non-interactively, `htmlize-buffer' and `htmlize-region' will
;; return the resulting HTML buffer, but will not change current
;; buffer or move the point.  htmlize will do its best to work on
;; non-windowing Emacs sessions but the result will be limited to
;; colors supported by the terminal.

;; htmlize aims for compatibility with Emacsen version 21 and later.
;; Please let me know if it doesn't work on the version of XEmacs or
;; GNU Emacs that you are using.  The package relies on the presence
;; of CL extensions, especially for cross-emacs compatibility; please
;; don't try to remove that dependency.  I see no practical problems
;; with using the full power of the CL extensions, except that one
;; might learn to like them too much.

;; The latest version is available as a git repository at:
;;
;;        
;;
;; The snapshot of the latest release can be obtained at:
;;
;;

;; You can find a sample of htmlize's output (possibly generated with
;; an older version) at:

;;        

;; Thanks go to the many people who have sent reports and contributed
;; comments, suggestions, and fixes.  They include Ron Gut, Bob
;; Weiner, Toni Drabik, Peter Breton, Ville Skytta, Thomas Vogels,
;; Juri Linkov, Maciek Pasternacki, and many others.

your documents to render correctly.  Also, the W3C validator requires
submitted HTML documents to declare a charset.  So if you care about

Needless to say, if you set this, you should actually make sure that

code point of the character.  If the code point cannot be determined,
the character will be copied unchanged, as would be the case if the

When the option is nil, the non-ASCII characters are copied to HTML
without modification.  In that case, the web server and/or the browser
must be set to understand the encoding that was used when saving the
buffer.  (You might also want to specify it by setting
`htmlize-html-charset'.)

Note that in an HTML entity \"&#CODE;\", CODE is always a UCS code point,
which has nothing to do with the charset the page is in.  For example,
\"©\" *always* refers to the copyright symbol, regardless of charset
specified by the META tag or the charset sent by the HTTP server.  In

;;; Commentary:
;;
;; This library implements a KOMA Scrlttr2 back-end, derived from the
;; LaTeX one.
;;
;; Depending on the desired output format, three commands are provided
;; for export: `org-koma-letter-export-as-latex' (temporary buffer),
;; `org-koma-letter-export-to-latex' ("tex" file) and
;; `org-koma-letter-export-to-pdf' ("pdf" file).
;;
;; On top of buffer keywords supported by `latex' back-end (see
;; `org-latex-options-alist'), this back-end introduces the following
;; keywords:
;;   - "CLOSING" (see `org-koma-letter-closing'),
;;   - "FROM_ADDRESS" (see `org-koma-letter-from-address'),
;;   - "LCO" (see `org-koma-letter-class-option-file'),
;;   - "OPENING" (see `org-koma-letter-opening'),
;;   - "PHONE_NUMBER" (see `org-koma-letter-phone-number'),
;;   - "SIGNATURE" (see `org-koma-letter-signature')
;;   - "PLACE" (see `org-koma-letter-place')
;;   - and "TO_ADDRESS".  If unspecified this is set to "\mbox{}".
;;
;; TO_ADDRESS and FROM_ADDRESS can also be specified using heading
;; with the special tags specified in
;; `org-koma-letter-special-tags-in-letter', namely "to" and "from".
;; LaTeX line breaks are not necessary if using these headings.  If
;; both a headline and a keyword specify a to or from address the
;; value is determined in accordance with
;; `org-koma-letter-prefer-special-headings'.
;;
;; A number of OPTIONS settings can be set to change which contents is
;; exported.
;;   - backaddress (see `org-koma-letter-use-backaddress')
;;   - foldmarks (see `org-koma-letter-use-foldmarks')
;;   - phone (see `org-koma-letter-use-phone')
;;   - email (see `org-koma-letter-use-email')
;;   - place (see `org-koma-letter-use-place')
;;   - subject, a list of format options
;;     (see `org-koma-letter-subject-format')
;;   - after-closing-order, a list of the ordering of headings with
;;     special tags after closing (see
;;     `org-koma-letter-special-tags-after-closing')
;;   - after-letter-order, as above, but after the end of the letter
;;     (see `org-koma-letter-special-tags-after-letter').
;;
;; The following variables works differently from the main LaTeX class
;;   - "AUTHOR": default to user-full-name but may be disabled.  (see org-koma-letter-author),
;;   - "EMAIL": same as AUTHOR, (see org-koma-letter-email),
;;
;; Headlines are in general ignored.  However, headlines with special
;; tags can be used for specified contents like postscript (ps),
;; carbon copy (cc), enclosures (encl) and code to be inserted after
;; \end{letter} (after_letter).  Specials tags are defined in
;; `org-koma-letter-special-tags-after-closing' and
;; `org-koma-letter-special-tags-after-letter'.  Currently members of
;; `org-koma-letter-special-tags-after-closing' used as macros and the
;; content of the headline is the argument.
;;
;; Headlines with two and from may also be used rather than the
;; keyword approach described above.  If both a keyword and a headline
;; with information is present precedence is determined by
;; `org-koma-letter-prefer-special-headings'.
;;
;; You will need to add an appropriate association in
;; `org-latex-classes' in order to use the KOMA Scrlttr2 class.
;; The easiest way to do this is by adding
;;
;;   (eval-after-load "ox-koma-letter"
;;   '(org-koma-letter-plug-into-ox))
;;
;; to your init file.  This will add a sparse scrlttr2 class and
;; set it as the default `org-koma-latex-default-class'.  You can also
;; add you own letter class.  For instace:
;;
;;   (add-to-list 'org-latex-classes
;;                '("my-letter"
;;                  "\\documentclass\[%
;;   DIV=14,
;;   fontsize=12pt,
;;   parskip=half,
;;   subject=titled,
;;   backaddress=false,
;;   fromalign=left,
;;   fromemail=true,
;;   fromphone=true\]\{scrlttr2\}
;;   \[DEFAULT-PACKAGES]
;;   \[PACKAGES]
;;   \[EXTRA]"))
;;
;; Then, in your Org document, be sure to require the proper class
;; with :
;;
;;    #+LATEX_CLASS: my-letter
;;
;; Or by setting `org-koma-letter-default-class'.

;;; Commentary:
;;
;; This gives you a chance to get rid of old entries in your Org files
;; by expiring them.
;;
;; By default, entries that have no EXPIRY property are considered to be
;; new (i.e. 0 day old) and only entries older than one year go to the
;; expiry process, which consist in adding the ARCHIVE tag.  None of
;; your tasks will be deleted with the default settings.
;;
;; When does an entry expires?
;;
;; Consider this entry:
;;
;; * Stop watching TV
;;   :PROPERTIES:
;;   :CREATED:  <2008-01-07 lun 08:01>
;;   :EXPIRY:   <2008-01-09 08:01>
;;   :END:
;;
;; This entry will expire on the 9th, january 2008.

;; * Stop watching TV
;;   :PROPERTIES:
;;   :CREATED:  <2008-01-07 lun 08:01>
;;   :EXPIRY:   +1w
;;   :END:
;;
;; This entry will expire on the 14th, january 2008, one week after its
;; creation date.
;;
;; What happen when an entry is expired?  Nothing until you explicitely
;; M-x org-expiry-process-entries When doing this, org-expiry will check
;; for expired entries and request permission to process them.
;;
;; Processing an expired entries means calling the function associated
;; with `org-expiry-handler-function'; the default is to add the tag
;; :ARCHIVE:, but you can also add a EXPIRED keyword or even archive
;; the subtree.
;;
;; Is this useful?  Well, when you're in a brainstorming session, it
;; might be useful to know about the creation date of an entry, and be
;; able to archive those entries that are more than xxx days/weeks old.
;;
;; When you're in such a session, you can insinuate org-expiry like
;; this: M-x org-expiry-insinuate
;;
;; Then, each time you're pressing M-RET to insert an item, the CREATION
;; property will be automatically added.  Same when you're scheduling or
;; deadlining items.  You can deinsinuate: M-x org-expiry-deinsinuate

;; Org-mode already lets you store/insert links to emacs-lisp files,
;; just like any other file.  This package lets you precisely link to
;; any emacs-lisp symbol and access useful information about the symbol.
;;
;; Here is the list of available properties when linking from a elisp-symbol:
;;
;; :name        The symbol's name.
;; :stype       The symbol's type (commandp, function, etc.)
;; :def         The function used to set the symbol's value (defun, etc.)
;; :keys        The keys associated with the command.
;; :args        The arguments of the function.
;; :docstring   The docstring of the symbol.
;; :doc         The first line of the dostring.
;; :comment     A comment line just above the sexp, if any.
;; :fixme       A FIXME comment line just above the sexp, if any.
;;
;; Let's say we have a defun like this one:
;;
;; ;; FIXME update docstring
;; (defun org-export-latex-lists ()
;;   "Convert lists to LaTeX."
;;   (goto-char (point-min))
;;   (while (re-search-forward org-export-latex-list-beginning-re nil t)
;;     (beginning-of-line)
;;     (insert (org-list-to-latex (org-list-parse-list t)) "\n")))
;;
;; And a remember template like:
;;
;; (setq org-remember-templates
;;   '((?s "* DEBUG `%:name' (%:args)\n\n%?\n\nFixme: %:fixme\n  \
;;          Doc: \"%:doc\"\n\n%a")))

;;; Commentary:

;; This file implements links to Mew messages from within Org-mode.
;; Org-mode loads this module by default - if this is not what you want,
;; configure the variable `org-modules'.
;;
;; Here is an example of workflow:

;; In your ~/.mew.el configuration file:
;;
;; (define-key mew-summary-mode-map "'" 'org-mew-search)
;; (eval-after-load "mew-summary"
;;   '(define-key mew-summary-mode-map "\C-o" 'org-mew-capture))

;; 1. In the Mew's inbox folder, take a glance at new messages to find
;;    a message that requires any action.

;; 2. If the message is a reply from somebody and associated with the
;;    existing orgmode entry, type M-x `org-mew-search' RET (or press
;;    the ' key simply) to find the entry.  If you can find the entry
;;    successfully and think you should start the task right now,
;;    start the task by M-x `org-agenda-clock-in' RET.

;; 3. If the message is a new message, type M-x `org-mew-capture' RET,
;;    enter the refile folder, and the buffer to capture the message
;;    is shown up (without selecting the template by hand).  Then you
;;    can fill the template and type C-c C-c to complete the capture.
;;    Note that you can configure `org-capture-templates' so that the
;;    captured entry has a link to the message.

;; USAGE NOTE
;;
;; You will need to configure mairix first, which involves setting up your
;; .mairixrc in your home directory. Once it is working, you should set up
;; your way to display results in your favorite way -- usually a MUA.
;; Currently gnus and mutt are supported.
;;
;; After both steps are done, all you should need to hook mairix, org
;; and your MUA together is to do (require 'org-mairix) in your
;; startup file. Everything can then be configured normally through
;; Emacs customisation.

;;; Commentary:

;; This file provides some functions for handing repeated tasks which involve
;; checking off a list of items. By setting the RESET_CHECK_BOXES property in an
;; item, when the TODO state is set to done all checkboxes under that item are
;; cleared. If the LIST_EXPORT_BASENAME property is set, a file will be created
;; using the value of that property plus a timestamp, containing all the items
;; in the list which are not checked. Additionally the user will be prompted to
;; print the list.
;;
;; I use this for to keep track of stores of various things (food stores,
;; components etc) which I check periodically and use the exported list of items
;; which are not present as a shopping list.
;;
;;; Usage:
;; (require 'org-checklist)

;; Set the RESET_CHECK_BOXES and LIST_EXPORT_BASENAME properties in items as
;; needed.

;;; Commentary:
;;
;; This file provides the import of events from Mac OS X 10.5 iCal.app
;; into the Emacs diary (it is not compatible with OS X < 10.5). The
;; function org-mac-iCal will import events in all checked iCal.app
;; calendars for the date range org-mac-iCal-range months, centered
;; around the current date.
;;
;; CAVEAT: This function is destructive; it will overwrite the current
;; contents of the Emacs diary.
;;
;; Installation: add (require 'org-mac-iCal) to your .emacs.
;;
;; If you view Emacs diary entries in org-agenda, the following hook
;; will ensure that all-day events are not orphaned below TODO items
;; and that any supplementary fields to events (e.g. Location) are
;; grouped with their parent event

;;; Commentary:

;; This library implements a RSS 2.0 back-end for Org exporter, based on
;; the `html' back-end.
;;
;; It requires Emacs 24.1 at least.
;;
;; It provides two commands for export, depending on the desired output:
;; `org-rss-export-as-rss' (temporary buffer) and `org-rss-export-to-rss'
;; (as a ".xml" file).
;;
;; This backend understands two new option keywords:
;;
;; #+RSS_EXTENSION: xml
;; #+RSS_IMAGE_URL: http://myblog.org/mypicture.jpg
;;
;; It uses #+HTML_LINK_HOME: to set the base url of the feed.
;;
;; Exporting an Org file to RSS modifies each top-level entry by adding a
;; PUBDATE property.  If `org-rss-use-entry-url-as-guid', it will also add
;; an ID property, later used as the guid for the feed's item.
;;
;; You typically want to use it within a publishing project like this:
;;
;; (add-to-list
;;  'org-publish-project-alist
;;  '("homepage_rss"
;;    :base-directory "~/myhomepage/"
;;    :base-extension "org"
;;    :rss-image-url "http://lumiere.ens.fr/~guerry/images/faces/15.png"
;;    :html-link-home "http://lumiere.ens.fr/~guerry/"
;;    :html-link-use-abs-url t
;;    :rss-extension "xml"
;;    :publishing-directory "/home/guerry/public_html/"
;;    :publishing-function (org-rss-publish-to-rss)
;;    :section-numbers nil
;;    :exclude ".*"            ;; To exclude all files...
;;    :include ("index.org")   ;; ... except index.org.
;;    :table-of-contents nil))
;;
;; ... then rsync /home/guerry/public_html/ with your server.
;;
;; By default, the permalink for a blog entry points to the headline.
;; You can specify a different one by using the :RSS_PERMALINK:
;; property within an entry.

;;; Commentary:
;;
;; This library add a registry to your Org setup.
;;
;; Org files are full of links inserted with `org-store-link'. This links
;; point to e-mail, webpages, files, dirs, info pages, man pages, etc.
;; Actually, they come from potentially *everywhere* since Org lets you
;; define your own storing/following functions.
;;
;; So, what if you are on a e-mail, webpage or whatever and want to know if
;; this buffer has already been linked to somewhere in your agenda files?
;;
;; This is were org-registry comes in handy.
;;
;;     M-x org-registry-show will tell you the name of the file
;; C-u M-x org-registry-show will directly jump to the file
;;
;; In case there are several files where the link lives in:
;;
;;     M-x org-registry-show will display them in a new window
;; C-u M-x org-registry-show will prompt for a file to visit
;;
;; Add this to your Org configuration:
;;
;; (require 'org-registry)
;; (org-registry-initialize)
;;
;; If you want to update the registry with newly inserted links in the
;; current buffer: M-x org-registry-update
;;
;; If you want this job to be done each time you save an Org buffer,
;; hook 'org-registry-update to the local 'after-save-hook in org-mode:
;;
;; (org-registry-insinuate)

;;; Commentary:
;;
;; This is an utility to handle BibTeX export to both LaTeX and html
;; exports.  It uses the bibtex2html software from:
;;
;;   http://www.lri.fr/~filliatr/bibtex2html/
;;
;; It also introduces "cite" syntax for Org links.
;;
;; The usage is as follows:
;;
;;   #+BIBLIOGRAPHY: bibfilebasename stylename optional-options
;;
;; e.g. given foo.bib and using style plain:
;;
;;   #+BIBLIOGRAPHY: foo plain option:-d
;;
;; Optional options are of the form:
;;
;;   option:-foobar pass '-foobar' to bibtex2html
;;
;; e.g.,
;;
;;   option:-d    sort by date
;;   option:-a    sort as BibTeX (usually by author) *default*
;;   option:-u    unsorted i.e. same order as in .bib file
;;   option:-r    reverse the sort
;;
;; See the bibtex2html man page for more.  Multiple options can be
;; combined like:
;;
;;   option:-d option:-r
;;
;; Limiting to only the entries cited in the document:
;;
;;   limit:t
;;
;; For LaTeX export this simply inserts the lines
;;
;;   \bibliographystyle{plain}
;;   \bibliography{foo}
;;
;; into the TeX file when exporting.
;;
;; For HTML export it:
;; 1) converts all \cite{foo} and [[cite:foo]] to links to the
;;    bibliography,
;; 2) creates a foo.html and foo_bib.html,
;; 3) includes the contents of foo.html in the exported HTML file.
;;
;; For LaTeX export it:
;; 1) converts all [[cite:foo]] to \cite{foo}.

;;
;;; Commentary:
;;
;; This code allows you to grab either the current selected items, or
;; the frontmost url in various mac appliations, and insert them as
;; hyperlinks into the current org-mode document at point.
;;
;; This code is heavily based on, and indeed incorporates,
;; org-mac-message.el written by John Wiegley and Christopher
;; Suckling.
;;
;; Detailed comments for each application interface are inlined with
;; the code.  Here is a brief overview of how the code interacts with
;; each application:
;;
;; Finder.app - grab links to the selected files in the frontmost window
;; Mail.app - grab links to the selected messages in the message list
;; AddressBook.app - Grab links to the selected addressbook Cards
;; Firefox.app - Grab the url of the frontmost tab in the frontmost window
;; Vimperator/Firefox.app - Grab the url of the frontmost tab in the frontmost window
;; Safari.app - Grab the url of the frontmost tab in the frontmost window
;; Google Chrome.app - Grab the url of the frontmost tab in the frontmost window
;; Together.app - Grab links to the selected items in the library list
;; Skim.app - Grab a link to the selected page in the topmost pdf document
;; Microsoft Outlook.app - Grab a link to the selected message in the message list
;;
;;
;; Installation:
;;
;; add (require 'org-mac-link) to your .emacs, and optionally bind a
;; key to activate the link grabber menu, like this:
;;
;; (add-hook 'org-mode-hook (lambda ()
;;   (define-key org-mode-map (kbd "C-c g") 'org-mac-grab-link)))
;;
;; Usage:
;;
;; Type C-c g (or whatever key you defined, as above), or type M-x
;; org-mac-grab-link RET to activate the link grabber.  This will present
;; you with a menu to choose an application from which to grab a link
;; to insert at point.  You may also type C-g to abort.
;;
;; Customizing:
;;
;; You may customize which applications appear in the grab menu by
;; customizing the group `org-mac-link'.  Changes take effect
;; immediately.

;; Handle links from Firefox.app
;;
;; This code allows you to grab the current active url from the main
;; Firefox.app window, and insert it as a link into an org-mode
;; document. Unfortunately, firefox does not expose an applescript
;; dictionary, so this is necessarily introduces some limitations.
;;
;; The applescript to grab the url from Firefox.app uses the System
;; Events application to give focus to the firefox application, select
;; the contents of the url bar, and copy it. It then uses the title of
;; the window as the text of the link. There is no way to grab links
;; from other open tabs, and further, if there is more than one window
;; open, it is not clear which one will be used (though emperically it
;; seems that it is always the last active window).

;;; Commentary:
;;
;; This file contains functionality to integrate screen and org-mode.
;; When using org-mode, it is often useful to take tasks that have
;; some command-line work associated with them, and associate them
;; with a screen session.  Screen is used rather than a direct
;; terminal to facilitate portability of the resulting session.
;;
;; To use screen in org, in your .emacs file, simply put this file in
;; a directory in your load-path and write:
;;
;; (require 'org-screen)
;;
;; When have a task and want to start some command-line activity
;; associated with that task, go to the end of your item and type:
;;
;; M-x org-screen
;;
;; This will prompt you for a name of a screen session.  Type in a
;; name and it will insert a link into your org file at your current
;; location.
;;
;; When you want to visit the link, go to the link and type C-c C-o to
;; open the link.
;;
;; You may want to get rid of the constant queries about whether you
;; really want to execute lisp code.  Do so by adding to your .emacs:

;;; Commentary:

;; This is code to support decision management.  It lets you treat a
;; group of sibling items in org-mode as alternatives in a decision.

;; There are no user commands in this file.  You use it by:
;;   * Loading it (manually or by M-x customize-apropos org-modules)

;;   * Setting up at least one set of TODO keywords with the
;;     interpretation "choose" by either:

;;     * Using the file directive #+CHOOSE_TODO:

;;       * For instance, "#+CHOOSE_TODO: NO(,-) MAYBE(,0) YES"

;;     * Or by M-x customize-apropos org-todo-keywords

;;   * Operating on single items with the TODO commands.

;;     * Use C-S-right to change the keyword set.  Use this to change to
;;       the "choose" keyword set that you just defined.

;;     * Use S-right to advance the TODO mark to the next setting.

;;       For "choose", that means you like this alternative more than
;;       before.  Other alternatives will be automatically demoted to
;;       keep your settings consistent.

;;     * Use S-left to demote TODO to the previous setting.

;;       For "choose", that means you don't like this alternative as much
;;       as before.  Other alternatives will be automatically promoted,
;;       if this item was all that was keeping them down.

;;     * All the other TODO commands are available and behave essentially
;;       the normal way.

;;
;; Each drill session can be restricted to topics in the current buffer
;; (default), one or several files, all agenda files, or a subtree. A single

;; Different "card types" can be defined, which present their information to

topic. This rating information is used to reschedule the topic
for future review.

Org-drill proceeds by:

- Finding all topics (headings) in SCOPE which have either been
  used and rescheduled before, or which have a tag that matches
  `org-drill-question-tag'.

- All matching topics which are either unscheduled, or are
  scheduled for the current date or a date in the past, are
  considered to be candidates for the drill session.

- If `org-drill-maximum-items-per-session' is set, a random
  subset of these topics is presented. Otherwise, all of the
  eligible topics will be presented.

SCOPE determines the scope in which to search for
questions.  It accepts the same values as `org-drill-scope',
which see.

If RESUME-P is non-nil, resume a suspended drill session rather
than starting a new one."

;;; Commentary:

;; This is yet another implementation to allow the annotation of a
;; file without modification of the file itself. The annotation is in
;; org syntax so you can use all of the org features you are used to.

;; To use you might put the following in your .emacs:
;;
;; (require 'org-annotate-file)
;; (global-set-key (kbd "C-c C-l") 'org-annotate-file) ; for example
;;
;; To change the location of the annotation file:
;;
;; (setq org-annotate-file-storage-file "~/annotated.org")
;;
;; Then when you visit any file and hit C-c C-l you will find yourself
;; in an org buffer on a headline which links to the file you were
;; visiting, e.g:

;; * ~/org-annotate-file.el

;; Under here you can put anything you like, save the file
;; and next time you hit C-c C-l you will hit those notes again.
;;
;; To put a subheading with a text search for the current line set
;; `org-annotate-file-add-search` to non-nil value. Then when you hit
;; C-c C-l (on the above line for example) you will get:

;; * ~/org-annotate-file.el
;; ** `org-annotate-file-add-search` to non-nil value. Then whe...

;; Note that both of the above will be links.

;; This library implements a deck.js presentation back-end for the Org
;; generic exporter.

;; Installation
;; -------------
;; Get a copy of deck.js from http://imakewebthings.com/deck.js/ or
;; the gitub repository at https://github.com/imakewebthings/deck.js.
;;
;; Add the path to the extracted code to the variable
;; `org-deck-directories' There are a number of customization in the
;; org-export-deck group, most of which can be overrriden with buffer
;; local customization (starting with DECK_.)

;; See ox.el and ox-html.el for more details on how this exporter
;; works (it is derived from ox-html.)

*** Agenda

**** =org-agenda-custom-commands= has a default value

     This option used to be `nil' by default.  This now has a default
     value, displaying an agenda and all TODOs.  See the docstring for
     details.  Thanks to Carsten for this.

**** Improved filtering through =org-agenda-to-appt=

     The new function allows the user to refine the scope of entries
     to pass to =org-agenda-get-day-entries= and allows to filter out
     entries using a function.

     Thanks to Peter Münster for raising a related issue and to
     Tassilo Horn for this idea.  Also thanks to Peter Münster for
     [[git:68ffb7a7][fixing a small bug]] in the final implementation.

**** Allow ap/pm times in agenda time grid

     Times in the agenda can now be displayed in am/pm format.  See
     the new variable =org-agenda-timegrid-use-ampm=.  Thanks to
     C. A. Webber for a patch to this effect.

**** Agenda: Added a bulk "scattering" command

     =B S= in the agenda buffer will cause tasks to be rescheduled a
     random number of days into the future, with 7 as the default.
     This is useful if you've got a ton of tasks scheduled for today,
     you realize you'll never deal with them all, and you just want
     them to be distributed across the next N days.  When called with
     a prefix arg, rescheduling will avoid weekend days.

     Thanks to John Wiegley for this.

*** Exporting

**** Simplification of org-export-html-preamble/postamble

     When set to `t', export the preamble/postamble as usual, honoring
     the =org-export-email/author/creator-info= variables.

     When set to a formatting string, insert this string.  See the
     docstring of these variable for details about available
     %-sequences.

     You can set =:html-preamble= in publishing project in the same
     way: `t' means to honor =:email/creator/author-info=, and a
     formatting string will insert a string.

**** New exporters to Latin-1 and UTF-8

     While Ulf Stegemann was going through the entities list to
     improve the LaTeX export, he had the great idea to provide
     representations for many of the entities in Latin-1, and for all
     of them in UTF-8.  This means that we can now export files rich
     in special symbols to Latin-1 and to UTF-8 files.  These new
     exporters can be reached with the commands =C-c C-e n= and =C-c
     C-e u=, respectively.

     When there is no representation for a given symbol in the
     targeted coding system, you can choose to keep the TeX-macro-like
     representation, or to get an "explanatory" representation.  For
     example, =\simeq= could be represented as "[approx. equal to]".
     Please use the variable =org-entities-ascii-explanatory= to state
     your preference.

**** HTML export: Add class to outline containers using property

     The =HTML_CONTAINER_CLASS= property can now be used to add a
     class name to the outline container of a node in HTML export.

**** Throw an error when creating an image from a LaTeX snippet fails

     This behavior can be configured with the new option variable
     =org-format-latex-signal-error=.

**** Support for creating BEAMER presentations from Org-mode documents

     Org-mode documents or subtrees can now be converted directly in
     to BEAMER presentation.  Turning a tree into a simple
     presentations is straight forward, and there is also quite some
     support to make richer presentations as well.  See the [[http://orgmode.org/manual/Beamer-class-export.html#Beamer-class-export][BEAMER
     section]] in the manual for more details.

     Thanks to everyone who has contributed to the discussion about
     BEAMER support and how it should work.  This was a great example
     for how this community can achieve a much better result than any
     individual could.

*** Refiling

**** Refile targets can now be cached

     You can turn on caching of refile targets by setting the variable
     =org-refile-use-cache=.  This should speed up refiling if you
     have many eligible targets in many files.  If you need to update
     the cache because Org misses a newly created entry or still
     offers a deleted one, press =C-0 C-c C-w=.

**** New logging support for refiling

     Whenever you refile an item, a time stamp and even a note can be
     added to this entry.  For details, see the new option
     =org-log-refile=.

     Thanks to Charles Cave for this idea.

*** Completion

**** In-buffer completion is now done using John Wiegley's pcomplete.el

     Thanks to John Wiegley for much of this code.

*** Tables

**** New command =org-table-transpose-table-at-point=

     See the docstring.  This hack from Juan Pechiar is now part of
     Org's core.  Thanks to Juan!

**** Display field's coordinates when editing it with =C-c `=

     When editing a field with =C-c `=, the field's coordinate will
     the displayed in the buffer.

     Thanks to Michael Brand for a patch to this effect.

**** Spreadsheet computation of durations and time values

     If you want to compute time values use the =T= flag, either in
     Calc formulas or Elisp formulas:

     | Task 1 | Task 2 |   Total |
     |--------+--------+---------|
     |  35:00 |  35:00 | 1:10:00 |
     #+TBLFM: @2$3=$1+$2;T

     Values must be of the form =[HH:]MM:SS=, where hours are
     optional.

     Thanks to Martin Halder, Eric Schulte and Carsten for code and
     feedback on this.

**** Implement formulas applying to field ranges

     Carsten implemented this field-ranges formulas.

     : A frequently requested feature for tables has been to be able to define
     : row formulas in a way similar to column formulas.  The patch below allows
     : things like
     :
     : @3=
     : @2$2..@5$7=
     : @I$2..@II$4=
     :
     : as the left hand side for table formulas in order to write a formula that
     : is valid for an entire column or for a rectangular section in a
     : table.

     Thanks a lot to Carsten for this.

**** Sending radio tables from org buffers is now allowed

     Org radio tables can no also be sent inside Org buffers.  Also,
     there is a new hook which get called after a table has been sent.

     Thanks to Seweryn Kokot.

*** Lists

**** Improved handling of lists

     Nicolas Goaziou extended and improved the way Org handles lists.

     1. Indentation of text determines again end of items in
        lists. So, some text less indented than the previous item
        doesn't close the whole list anymore, only all items more
        indented than it.

     2. Alphabetical bullets are implemented, through the use of the
        variable `org-alphabetical-lists'. This also adds alphabetical
        counters like [@c] or [@W].

     3. Lists can now safely contain drawers, inline tasks, or various
        blocks, themselves containing lists. Two variables are
        controlling this: `org-list-forbidden-blocks', and
        `org-list-export-context'.

     4. Improve `newline-and-indent' (C-j): used in an item, it will
        keep text from moving at column 0. This allows to split text
        and make paragraphs and still not break the list.

     5. Improve `org-toggle-item' (C-c -): used on a region with
        standard text, it will change the region into one item. With a
        prefix argument, it will fallback to the previous behavior and
        make every line in region an item. It permits to easily
        integrate paragraphs inside a list.

     6. `fill-paragraph' (M-q) now understands lists. It can freely be
        used inside items, or on text just after a list, even with no
        blank line around, without breaking list structure.

     Thanks a lot to Nicolas for all this!

*** Inline display of linked images

    Images can now be displayed inline.  The key C-c C-x C-v does
    toggle the display of such images.  Note that only image links
    that have no description part will be inlined.

*** Implement offsets for ordered lists

    If you want to start an ordered plain list with a number different
    from 1, you can now do it like this:

    : 1. [@start:12] will star a lit a number 12

*** Babel: code block body expansion for table and preview

    In org-babel, code is "expanded" prior to evaluation. I.e. the
    code that is actually evaluated comprises the code block contents,
    augmented with the extra code which assigns the referenced data to
    variables. It is now possible to preview expanded contents, and
    also to expand code during during tangling. This expansion takes
    into account all header arguments, and variables.

    A new keybinding `C-c M-b p' bound to `org-babel-expand-src-block'
    can be used from inside of a source code block to preview its
    expanded contents (which can be very useful for debugging).
    tangling

    The expanded body can now be tangled, this includes variable
    values which may be the results of other source-code blocks, or
    stored in headline properties or tables. One possible use for this
    is to allow those using org-babel for their emacs initialization
    to store values (e.g. usernames, passwords, etc...) in headline
    properties or in tables.

    Org-babel now supports three new header arguments, and new default
    behavior for handling horizontal lines in tables (hlines), column
    names, and rownames across all languages.

*** Editing Convenience and Appearance

**** New command =org-copy-visible= (=C-c C-x v=)

     This command will copy the visible text in the region into the
     kill ring.  Thanks to Florian Beck for this function and to
     Carsten for adding it to org.el and documenting it!

**** Make it possible to protect hidden subtrees from being killed by =C-k=

     See the new variable =org-ctrl-k-protect-subtree=.  This was a
     request by Scott Otterson.

**** Implement pretty display of entities, sub-, and superscripts.

     The command =C-c C-x \= toggles the display of Org's special
     entities like =\alpha= as pretty unicode characters.  Also, sub
     and superscripts are displayed in a pretty way (raised/lower
     display, in a smaller font).  If you want to exclude sub- and
     superscripts, see the variable
     =org-pretty-entities-include-sub-superscripts=.

     Thanks to Eric Schulte and Ulf Stegeman for making this possible.

**** New faces for title, date, author and email address lines

     The keywords in these lines are now dimmed out, and the title is
     displayed in a larger font, and a special font is also used for
     author, date, and email information.  This is implemented by the
     following new faces:

     =org-document-title=
     =org-document-info=
     =org-document-info-keyword=

     In addition, the variable =org-hidden-keywords= can be used to
     make the corresponding keywords disappear.

     Thanks to Dan Davison for this feature.

**** Simpler way to specify faces for tags and todo keywords

     The variables =org-todo-keyword-faces=, =org-tag-faces=, and
     =org-priority-faces= now accept simple color names as
     specifications.  The colors will be used as either foreground or
     background color for the corresponding keyword.  See also the
     variable =org-faces-easy-properties=, which governs which face
     property is affected by this setting.

     This is really a great simplification for setting keyword faces.
     The change is based on an idea and patch by Ryan Thompson.

****  in tables now means fixed width, not maximum width

     Requested by Michael Brand.

**** Better level cycling function

     =TAB= in an empty headline cycles the level of that headline
     through likely states.  Ryan Thompson implemented an improved
     version of this function, which does not depend upon when exactly
     this command is used.  Thanks to Ryan for this improvement.

**** Adaptive filling

     For paragraph text, =org-adaptive-fill-function= did not handle
     the base case of regular text which needed to be filled.  This is
     now fixed.  Among other things, it allows email-style ">"
     comments to be filled correctly.

     Thanks to Dan Hackney for this patch.

**** `org-reveal' (=C-c C-r=) also decrypts encrypted entries (org-crypt.el)

     Thanks to Richard Riley for triggering this change.

**** Better automatic letter selection for TODO keywords

     When all first letters of keywords have been used, Org now
     assigns more meaningful characters based on the keywords.

     Thanks to Mikael Fornius for this patch.

*** Clocking

**** Clock: Allow synchronous update of timestamps in CLOCK log

     Using =S-M-= on CLOCK log timestamps will
     increase/decrease the two timestamps on this line so that
     duration will keep the same.  Note that duration can still be
     slightly modified in case a timestamp needs some rounding.

     Thanks to Rainer Stengele for this idea.

**** Localized clock tables

     Clock tables now support a new new =:lang= parameter, allowing
     the user to customize the localization of the table headers.  See
     the variable =org-clock-clocktable-language-setup= which controls
     available translated strings.

**** Show clock overruns in mode line

     When clocking an item with a planned effort, overrunning the
     planned time is now made visible in the mode line, for example
     using the new face =org-mode-line-clock-overrun=, or by adding an
     extra string given by =org-task-overrun-text=.

     Thanks to Richard Riley for a patch to this effect.

**** Clock reports can now include the running, incomplete clock

     If you have a clock running, and the entry being clocked falls
     into the scope when creating a clock table, the time so far spent
     can be added to the total.  This behavior depends on the setting
     of =org-clock-report-include-clocking-task=.  The default is
     =nil=.

     Thanks to Bernt Hansen for this useful addition.

*** Misc

**** Improvements with inline tasks and indentation

     There is now a configurable way on how to export inline tasks.
     See the new variable =org-inlinetask-export-templates=.

     Thanks to Nicolas Goaziou for coding these changes.

**** A property value of "nil" now means to unset a property

     This can be useful in particular with property inheritance, if
     some upper level has the property, and some grandchild of it
     would like to have the default settings (i.e. not overruled by a
     property) back.

     Thanks to Robert Goldman and Bernt Hansen for suggesting this
     change.

**** New helper functions in org-table.el

     There are new functions to access and write to a specific table field.
     This is for hackers, and maybe for the org-babel people.

     #+begin_example
     org-table-get
     org-table-put
     org-table-current-line
     org-table-goto-line
     #+end_example

**** Archiving: Allow to reverse order in target node

     The new option =org-archive-reversed-order= allows to have
     archived entries inserted in a last-on-top fashion in the target
     node.

     This was requested by Tom.

**** Org-reveal: Double prefix arg shows the entire subtree of the parent

     This can help to get out of an inconsistent state produced for
     example by viewing from the agenda.

     This was a request by Matt Lundin.

OrgOdtContentTemplate.xml provides a template within which the content
of an exported document is enclosed.  This file contributes to
"content.xml" file within an exported document and acts as a
repository of automatic styles.

OrgOdtStyles.xml contributes to "styles.xml" file within an exported
document and acts as a repository of custom styles.

;; `org-macro--collect-macros' in order to read setup files.

;; Along with macros defined through #+MACRO: keyword, default
;; templates include the following hard-coded macros:
;; {{{time(format-string)}}}, {{{property(node-property)}}},
;; {{{input-file}}} and {{{modification-time(format-string)}}}.

;; Upon exporting, "ox.el" will also provide {{{author}}}, {{{date}}},
;; {{{email}}} and {{{title}}} macros.

  "Alist of LaTeX classes and associated header and structure.
If #+LATEX_CLASS is set in the buffer, use its value and the
associated information.  Here is the structure of each cell:

  \(class-name
    header-string
    \(numbered-section . unnumbered-section)
    ...)

The header string
-----------------

The HEADER-STRING is the header that will be inserted into the
LaTeX file.  It should contain the \\documentclass macro, and
anything else that is needed for this setup.  To this header, the
following commands will be added:

- Calls to \\usepackage for all packages mentioned in the
  variables `org-latex-default-packages-alist' and
  `org-latex-packages-alist'.  Thus, your header definitions
  should avoid to also request these packages.

- Lines specified via \"#+LATEX_HEADER:\" and
  \"#+LATEX_HEADER_EXTRA:\" keywords.

If you need more control about the sequence in which the header
is built up, or if you want to exclude one of these building
blocks for a particular class, you can use the following
macro-like placeholders.

 [DEFAULT-PACKAGES]      \\usepackage statements for default packages
 [NO-DEFAULT-PACKAGES]   do not include any of the default packages
 [PACKAGES]              \\usepackage statements for packages
 [NO-PACKAGES]           do not include the packages
 [EXTRA]                 the stuff from #+LATEX_HEADER(_EXTRA)
 [NO-EXTRA]              do not include #+LATEX_HEADER(_EXTRA) stuff

So a header like

  \\documentclass{article}
  [NO-DEFAULT-PACKAGES]
  [EXTRA]
  \\providecommand{\\alert}[1]{\\textbf{#1}}
  [PACKAGES]

will omit the default packages, and will include the
#+LATEX_HEADER and #+LATEX_HEADER_EXTRA lines, then have a call
to \\providecommand, and then place \\usepackage commands based
on the content of `org-latex-packages-alist'.

If your header, `org-latex-default-packages-alist' or
`org-latex-packages-alist' inserts \"\\usepackage[AUTO]{inputenc}\",
AUTO will automatically be replaced with a coding system derived
from `buffer-file-coding-system'.  See also the variable
`org-latex-inputenc-alist' for a way to influence this mechanism.

Likewise, if your header contains \"\\usepackage[AUTO]{babel}\",
AUTO will be replaced with the language related to the language
code specified by `org-export-default-language', which see.  Note
that constructions such as \"\\usepackage[french,AUTO,english]{babel}\"
are permitted.

The sectioning structure
------------------------

The sectioning structure of the class is given by the elements
following the header string.  For each sectioning level, a number
of strings is specified.  A %s formatter is mandatory in each
section string and will be replaced by the title of the section.

Instead of a cons cell (numbered . unnumbered), you can also
provide a list of 2 or 4 elements,

  \(numbered-open numbered-close)

or

  \(numbered-open numbered-close unnumbered-open unnumbered-close)

providing opening and closing strings for a LaTeX environment
that should represent the document section.  The opening clause
should have a %s to represent the section title.

Instead of a list of sectioning commands, you can also specify
a function name.  That function will be called with two
parameters, the (reduced) level of the headline, and a predicate
non-nil when the headline should be numbered.  It must return
a format string in which the section title will be added."

full file name, %b by the file base name (i.e. without directory
and extension parts) and %o by the base directory of the file.

The reason why this is a list is that it usually takes several
runs of `pdflatex', maybe mixed with a call to `bibtex'.  Org
does not have a clever mechanism to detect which of these
commands have to be run to get to a stable result, and it also
does not do any error checking.

By default, Org uses 3 runs of `pdflatex' to do the processing.
If you have texi2dvi on your system and if that does not cause
the infamous egrep/locale bug:

     http://lists.gnu.org/archive/html/bug-texinfo/2010-03/msg00031.html

then `texi2dvi' is the superior choice as it automates the LaTeX
build process by calling the \"correct\" combinations of
auxiliary programs.  Org does offer `texi2dvi' as one of the
customize options.  Alternatively, `rubber' and `latexmk' also
provide similar functionality.  The latter supports `biber' out
of the box.

Alternatively, this may be a Lisp function that does the
processing, so you could use this to apply the machinery of
AUCTeX or the Emacs LaTeX mode.  This function should accept the

  "Face for column display of entry properties.
This is actually only part of the face definition for the text in column view.
The following faces apply, with this priority.

1. The color of the reference face.  This is normally the level fact that
   is used in the outline.  In agenda-mode, it will be the face of the
   first character in the line.  The color is explicitly retained to
   make sure that the column line still looks a bit like the structure
   line it is masking.

2. The `org-column' face.

3. The remaining properties of the reference face.

Since column view works by putting overlays with a display property
over individual characters in the buffer, the face of the underlining
character (this might for example be the a TODO keyword) might still
shine through in some properties.  So when your column view looks
funny, with \"random\" colors, weight, strike-through, try to explicitly
set the properties in the `org-column' face.  For example, set
:underline to nil, or the :slant to `normal'.

Under XEmacs, the rules are simpler, because the XEmacs version of
column view defines special faces for each outline level.  See the file
`org-colview-xemacs.el' in Org's contrib/ directory for details."

;;; Commentary:

;; Functions for referencing data from the header arguments of a
;; org-babel block.  The syntax of such a reference should be

;;   #+VAR: variable-name=file:resource-id

;; - variable-name :: the name of the variable to which the value
;;                    will be assigned

;; - file :: path to the file containing the resource, or omitted if
;;           resource is in the current file

;; - resource-id :: the id or name of the resource

;; So an example of a simple src block referencing table data in the
;; same file would be

;;  #+NAME: sandbox
;;  | 1 |         2 | 3 |
;;  | 4 | org-babel | 6 |
;;
;;  #+begin_src emacs-lisp :var table=sandbox
;;    (message table)
;;  #+end_src

;;; Commentary:

;; Support for evaluating clojure code, relies on slime for all eval.

;;; Requirements:

;; - clojure (at least 1.2.0)
;; - clojure-mode
;; - slime

;; By far, the best way to install these components is by following
;; the directions as set out by Phil Hagelberg (Technomancy) on the
;; web page: http://technomancy.us/126

By default RESULT is inserted after the end of the

controls insertion of results in the org-mode file.
RESULT-PARAMS can take the following values:

replace - (default option) insert results after the source block
          replacing any previously inserted results

silent -- no results are inserted into the Org-mode buffer but
          the results are echoed to the minibuffer and are
          ingested by Emacs (a potentially time consuming
          process)

file ---- the results are interpreted as a file path, and are
          inserted into the buffer using the Org-mode file syntax

list ---- the results are interpreted as an Org-mode list.

raw ----- results are added directly to the Org-mode file.  This
          is a good option if you code block will output org-mode
          formatted text.

drawer -- results are added directly to the Org-mode file as with
          \"raw\", but are wrapped in a RESULTS drawer, allowing
          them to later be replaced or removed automatically.

org ----- results are added inside of a \"#+BEGIN_SRC org\" block.
          They are not comma-escaped when inserted, but Org syntax
          here will be discarded when exporting the file.

html ---- results are added inside of a #+BEGIN_HTML block.  This
          is a good option if you code block will output html
          formatted text.

latex --- results are added inside of a #+BEGIN_LATEX block.
          This is a good option if you code block will output
          latex formatted text.

code ---- the results are extracted in the syntax of the source
          code of the language being evaluated and are added
          inside of a #+BEGIN_SRC block with the source-code
          language set appropriately.  Note this relies on the

following structure:

LEVEL:     The level of the headline, as an integer.  This will be
           the reduced leve, so 1,2,3,... even if only odd levels
           are being used.
HEADLINE:  The text of the headline.  Depending on PARAMS, this may
           already be formatted like a link.
TIMESTAMP: If PARAMS require it, this will be a time stamp found in the
           entry, any of SCHEDULED, DEADLINE, NORMAL, or first inactive,
           in this sequence.
TIME:      The sum of all time spend in this tree, in minutes.  This time

- When formatting a source code snippet for export with htmlize.

You may want to use this hook for example to turn off `outline-minor-mode'
or similar things which you want to have when editing a source code file,
but which mess up the display of a snippet in Org exported files.")

The key is the language name, the value is the string that should

simple, but for language where this is not the case, this variable

For example, there is no ocaml-mode in Emacs, but the mode to use is
`tuareg-mode'."

;;; Commentary:

;; This is an implementation of dynamic virtual indentation.  It works
;; by adding text properties to a buffer to make sure lines are
;; indented according to outline structure.
;;
;; The process is synchronous, toggled at every buffer modification.
;; Though, the initialization (indentation of text already in the
;; buffer), which can take a few seconds in large buffers, happens on
;; idle time.

Show all entries that contain a phrase or words or regular expressions.

With optional prefix argument TODO-ONLY, only consider entries that are
TODO entries.  The argument STRING can be used to pass a default search
string into this function.  If EDIT-AT is non-nil, it means that the
user should get a chance to edit this string, with cursor at position
EDIT-AT.

The search string can be viewed either as a phrase that should be found as
is, or it can be broken into a number of snippets, each of which must match
in a Boolean way to select an entry.  The default depends on the variable
`org-agenda-search-view-always-boolean'.
Even if this is turned off (the default) you can always switch to
Boolean search dynamically by preceding the first word with  \"+\" or \"-\".

The default is a direct search of the whole phrase, where each space in
the search string can expand to an arbitrary amount of whitespace,
including newlines.

If using a Boolean search, the search string is split on whitespace and
each snippet is searched separately, with logical AND to select an entry.
Words prefixed with a minus must *not* occur in the entry.  Words without
a prefix or prefixed with a plus must occur in the entry.  Matching is
case-insensitive.  Words are enclosed by word delimiters (i.e. they must
match whole words, not parts of a word) if
`org-agenda-search-view-force-full-words' is set (default is nil).

Boolean search snippets enclosed by curly braces are interpreted as
regular expressions that must or (when preceded with \"-\") must not
match in the entry.  Snippets enclosed into double quotes will be taken
as a whole, to include whitespace.

- If the search string starts with an asterisk, search only in headlines.
- If (possibly after the leading star) the search string starts with an
  exclamation mark, this also means to look at TODO entries only, an effect
  that can also be achieved with a prefix argument.
- If (possibly after star and exclamation mark) the search string starts
  with a colon, this will mean that the (non-regexp) snippets of the
  Boolean search must match as full words.

slightly, to make sure a beginning of line in the first line is included.

SEPARATOR specifies the field separator in the lines.  It can have the
following values:

'(4)     Use the comma as a field separator
'(16)    Use a TAB as field separator
integer  When a number, use that many spaces as field separator
nil      When nil, the command tries to be smart and figure out the
         separator in the following way:
         - when each line contains a TAB, assume TAB-separated material
         - when each line contains a comma, assume CSV material
         - else, assume one or more SPACE characters as separator.

(autoload 'org-table-wrap-region "org-table" "\
Wrap several fields in a column like a paragraph.
This is useful if you'd like to spread the contents of a field over several
lines, in order to keep the table compact.

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
line down.

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 be 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.

PARAMS is a property list of parameters that can influence the conversion.
A third optional argument BACKEND can be used to convert the content of
the cells using a specific export back-end.

For the generic converter, some parameters are obligatory: you need to
specify either :lfmt, or all of (:lstart :lend :sep).

Valid parameters are:

:splice     When set to t, return only table body lines, don't wrap
            them into :tstart and :tend.  Default is nil.  When :splice
            is non-nil, this also means that the exporter should not look
            for and interpret header and footer sections.

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

:sep        Separator between two fields
:remove-nil-lines Do not include lines that evaluate to nil.

Each in the following group may be either a string or a function
of no arguments returning a string:

:tstart     String to start the table.  Ignored when :splice is t.
:tend       String to end the table.  Ignored when :splice is t.
:lstart     String to start a new table line.
:llstart    String to start the last table line, defaults to :lstart.
:lend       String to end a table line
:llend      String to end the last table line, defaults to :lend.

Each in the following group may be a string, a function of one
argument (the field or line) returning a string, or a plist
mapping columns to either of the above:

:lfmt       Format for entire line, with enough %s to capture all fields.
            If this is present, :lstart, :lend, and :sep are ignored.
:llfmt      Format for the entire last line, defaults to :lfmt.
: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 :hllstart :hlend :hllend :hlsep :hlfmt :hllfmt :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.

This may be either a string or a function of two arguments:

: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.

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.

can be exported as a structured ASCII or HTML file.

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 pressing 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

;;; Commentary:

;; This file implements globally unique identifiers for Org-mode entries.
;; Identifiers are stored in the entry as an :ID: property.  Functions
;; are provided that create and retrieve such identifiers, and that find
;; entries based on the identifier.

;; Identifiers consist of a prefix (default "Org" given by the variable
;; `org-id-prefix') and a unique part that can be created by a number
;; of different methods, see the variable `org-id-method'.
;; Org has a builtin method that uses a compact encoding of the creation
;; time of the ID, with microsecond accuracy.  This virtually
;; guarantees globally unique identifiers, even if several people are
;; creating IDs at the same time in files that will eventually be used
;; together.
;;
;; By default Org uses UUIDs as global unique identifiers.
;;
;; This file defines the following API:
;;
;; org-id-get-create
;;        Create an ID for the entry at point if it does not yet have one.
;;        Returns the ID (old or new).  This function can be used
;;        interactively, with prefix argument the creation of a new ID is
;;        forced, even if there was an old one.
;;
;; org-id-get
;;        Get the ID property of an entry.  Using appropriate arguments
;;        to the function, it can also create the ID for this entry.
;;
;; org-id-goto
;;        Command to go to a specific ID, this command can be used
;;        interactively.
;;
;; org-id-get-with-outline-path-completion
;;        Retrieve the ID of an entry, using outline path completion.
;;        This function can work for multiple files.
;;
;; org-id-get-with-outline-drilling
;;        Retrieve the ID of an entry, using outline path completion.
;;        This function only works for the current file.
;;
;; org-id-find
;;        Find the location of an entry with specific id.

;;; Commentary:
;;
;; Org-mouse provides mouse support for org-mode.
;;
;; http://orgmode.org
;;
;; Org-mouse implements the following features:
;; * following links with the left mouse button (in Emacs 22)
;; * subtree expansion/collapse (org-cycle) with the left mouse button
;; * several context menus on the right mouse button:
;;    + general text
;;    + headlines
;;    + timestamps
;;    + priorities
;;    + links
;;    + tags
;; * promoting/demoting/moving subtrees with mouse-3
;;    + if the drag starts and ends in the same line then promote/demote
;;    + otherwise move the subtree
;;
;; Use
;; ---
;;
;; To use this package, put the following line in your .emacs:
;;
;;    (require 'org-mouse)
;;

;; FIXME:
;; + deal with folding / unfolding issues

;; TODO (This list is only theoretical, if you'd like to have some
;; feature implemented or a bug fix please send me an email, even if
;; something similar appears in the list below.  This will help me get
;; the priorities right.):
;;
;; + org-store-link, insert link
;; + org tables
;; + occur with the current word/tag (same menu item)
;; + ctrl-c ctrl-c, for example, renumber the current list
;; + internal links

;; Please email the maintainer with new feature suggestions / bugs

;;; Commentary:
;;
;; This module implements inline tasks in Org-mode.  Inline tasks are
;; tasks that have all the properties of normal outline nodes,
;; including the ability to store meta data like scheduling dates,
;; TODO state, tags and properties.  However, these nodes are treated
;; specially by the visibility cycling.
;;
;; Visibility cycling exempts these nodes from cycling.  So whenever
;; their parent is opened, so are these tasks.  This will only work
;; with `org-cycle', so if you are also using other commands to
;; show/hide entries, you will occasionally find these tasks to behave
;; like all other outline nodes, seemingly splitting the text of the
;; parent into children.
;;
;; Special fontification of inline tasks, so that they can be
;; immediately recognized.  From the stars of the headline, only the
;; first and the last two will be visible, the others will be hidden
;; using the `org-hide' face.
;;
;; An inline task is identified solely by a minimum outline level,
;; given by the variable `org-inlinetask-min-level', default 15.
;;
;; If you need to have a time planning line (DEADLINE etc), drawers,
;; for example LOGBOOK of PROPERTIES, or even normal text as part of
;; the inline task, you must add an "END" headline with the same
;; number of stars.
;;
;; As an example, here are two valid inline tasks:
;;
;;    **************** TODO a small task
;;
;; and
;;
;;    **************** TODO another small task
;;                     DEADLINE: <2009-03-30 Mon>
;;                     :PROPERTIES:
;;                       :SOMETHING: or other
;;                     :END:
;;                     And here is some extra text
;;    **************** END
;;
;; Also, if you want to use refiling and archiving for inline tasks,
;; The END line must be present to make things work properly.
;;
;; Note that you should not try to use inline tasks within plain list,
;; visibility cycling is known to be problematic when doing so.
;;
;; This package installs one new command:
;;
;; C-c C-x t      Insert a new inline task with END line

;;; Commentary:

;; This file contains the code for creating and using the Agenda for Org-mode.
;;
;; The functions `org-batch-agenda', `org-batch-agenda-csv', and
;; `org-batch-store-agenda-views' are implemented as macros to provide
;; a convenient way for extracting agenda information from the command
;; line.  The Lisp does not evaluate parameters of a macro call; thus
;; it is not necessary to quote the parameters passed to one of those
;; functions.  E.g. you can write:
;;
;;   emacs -batch -l ~/.emacs -eval '(org-batch-agenda "a" org-agenda-span 7)'
;;
;; To export an agenda spanning 7 days.  If `org-batch-agenda' would
;; have been implemented as a regular function you'd have to quote the
;; symbol org-agenda-span.  Moreover: To use a symbol as parameter
;; value you would have to double quote the symbol.
;;
;; This is a hack, but it works even when running Org byte-compiled.
;;

               brackets.

  :sexp        List entries resulting from plain diary-like sexps.

  :deadline    List deadline due on that date.  When the date is today,

	       `org-deadline-warning-days'.  `:deadline' must appear before

Never set this variable globally using `setq', because then it
will apply to all future agenda commands.  Instead, bind it with
`let' to scope it dynamically into the agenda-constructing
command.  A good way to set it is through options in
`org-agenda-custom-commands'.  For a more flexible (though
somewhat less efficient) way of determining what is included in
the daily/weekly agenda, see `org-agenda-skip-function'.")

          todo-tree   Sparse tree of specific TODO keyword in *current* file.
          tags-tree   Sparse tree with all tags matches in *current* file.
          occur-tree  Occur sparse tree for *current* file.
          ...         A user-defined function.
match    What to search for:
          - a single keyword for TODO keyword searches
          - a tags match expression for tags searches
          - a word search expression for text searches.
          - a regular expression for occur searches
          For all other commands, this should be the empty string.
settings  A list of option settings, similar to that in a let form, so like
          this: ((opt1 val1) (opt2 val2) ...).   The values will be
          evaluated at the moment of execution, so quote them when needed.
files     A list of files file to write the produced agenda buffer to
          with the command `org-store-agenda-views'.
          If a file name ends in \".html\", an HTML version of the buffer
          is written out.  If it ends in \".ps\", a postscript version is
          produced.  Otherwise, only the plain text is written to the file.

You can also define a set of commands, to create a composite agenda buffer.
In this case, an entry looks like this:

  (key desc (cmd1 cmd2 ...) general-settings-for-whole-set files)

where

desc   A description string to be displayed in the dispatcher menu.
cmd    An agenda command, similar to the above.  However, tree commands
       are not allowed, but instead you can get agenda and global todo list.
       So valid commands for a set are:
       (agenda \"\" settings)
       (alltodo \"\" settings)
       (stuck \"\" settings)
       (todo \"match\" settings files)
       (search \"match\" settings files)
       (tags \"match\" settings files)
       (tags-todo \"match\" settings files)

Each command can carry a list of options, and another set of options can be
given for the whole set of commands.  Individual command options take
precedence over the general options.

When using several characters as key to a command, the first characters
are prefix commands.  For the dispatcher to display useful information, you
should provide a description for the prefix, like

 (setq org-agenda-custom-commands
   '((\"h\" . \"HOME + Name tag searches\") ; describe prefix \"h\"
     (\"hl\" tags \"+HOME+Lisa\")
     (\"hp\" tags \"+HOME+Peter\")
     (\"hk\" tags \"+HOME+Kim\")))"

2. A list of TODO keywords identifying non-stuck projects.

   a tag, any tag will mark the project unstuck.  Note that this is about
   the explicit presence of a tag somewhere in the subtree, inherited
   tags do not count here.  If inherited tags make a project not stuck,
   use \"-TAG\" in the tags part of the matcher under (1.) above.

All specifiers work basically like the standard `%s' of printf, but may

If the first character after `%' is a question mark, the entire field

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 is empty, no additional colon is inserted.

The default value for the agenda sublist is \"  %-12:c%?-12t% s\",
which means:

- Indent the line with two space characters
- Give the category 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.

See also the variables `org-agenda-remove-times-when-in-prefix' and
`org-agenda-remove-tags'.

M     Like `m', but select only TODO entries, no ordinary headlines.
L     Create a timeline for the current buffer.
e     Export views to associated files.
s     Search entries for keywords.
S     Search entries for keywords, only with TODO keywords.
/     Multi occur across all agenda files and also files listed
      in `org-agenda-text-search-extra-files'.
<     Restrict agenda commands to buffer, subtree, or region.
      Press several times to get the desired effect.
>     Remove a previous restriction.
#     List \"stuck\" projects.
!     Configure what \"stuck\" means.
C     Configure custom agenda commands.

More commands can be added by configuring the variable
`org-agenda-custom-commands'.  In particular, specific tags and TODO keyword
searches can be pre-defined in this way.

If the current buffer is in Org-mode and visiting a file, you can also
first press `<' once to indicate that the agenda should be temporarily
\(until the next use of \\[org-agenda]) restricted to the current file.
Pressing `<' twice means to restrict to the current subtree or region
\(if active)."

  "Show all entries that contain a phrase or words or regular expressions.

With optional prefix argument TODO-ONLY, only consider entries that are
TODO entries.  The argument STRING can be used to pass a default search
string into this function.  If EDIT-AT is non-nil, it means that the
user should get a chance to edit this string, with cursor at position
EDIT-AT.

The search string can be viewed either as a phrase that should be found as
is, or it can be broken into a number of snippets, each of which must match
in a Boolean way to select an entry.  The default depends on the variable
`org-agenda-search-view-always-boolean'.
Even if this is turned off (the default) you can always switch to
Boolean search dynamically by preceding the first word with  \"+\" or \"-\".

The default is a direct search of the whole phrase, where each space in
the search string can expand to an arbitrary amount of whitespace,
including newlines.

If using a Boolean search, the search string is split on whitespace and
each snippet is searched separately, with logical AND to select an entry.
Words prefixed with a minus must *not* occur in the entry.  Words without
a prefix or prefixed with a plus must occur in the entry.  Matching is
case-insensitive.  Words are enclosed by word delimiters (i.e. they must
match whole words, not parts of a word) if
`org-agenda-search-view-force-full-words' is set (default is nil).

Boolean search snippets enclosed by curly braces are interpreted as
regular expressions that must or (when preceded with \"-\") must not
match in the entry.  Snippets enclosed into double quotes will be taken
as a whole, to include whitespace.

- If the search string starts with an asterisk, search only in headlines.
- If (possibly after the leading star) the search string starts with an
  exclamation mark, this also means to look at TODO entries only, an effect
  that can also be achieved with a prefix argument.
- If (possibly after star and exclamation mark) the search string starts
  with a colon, this will mean that the (non-regexp) snippets of the
  Boolean search must match as full words.

Instead of a list, a keyword class may be given.  For example:

would skip entries that haven't been marked with any of \"DONE\"
keywords.  Possible classes are: `todo', `done', `any'.

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.  For a list of arguments allowed here, see the
variable `org-agenda-entry-types'.

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 value
of `org-agenda-entry-types' is used: (:deadline :scheduled :timestamp :sexp).
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

It has access to the text properties in that line, which contain among
other things, the property `org-hd-marker' that points to the entry
where the line comes from.  Note that not all lines going into the agenda
have this property, only most.

The function should return the modified string.  It is probably best
to ONLY change text properties.

You can also use this function as a filter, by returning nil for lines
you don't want to have in the agenda at all.  For this application, you
could bind the variable in the options section of a custom command.")

;;; Commentary:
;;
;; This software provides EMACS org-babel export support for message
;; sequence charts.  The mscgen utility is used for processing the
;; sequence definition, and must therefore be installed in the system.
;;
;; Mscgen is available and documented at
;; http://www.mcternan.me.uk/mscgen/index.html
;;
;; This code is directly inspired by Eric Schulte's ob-dot.el
;;
;; Example:
;;
;; #+begin_src mscgen :file example.png
;; msc {
;;  A,B;
;;  A -> B [ label = "send message" ];
;;  A <- B [ label = "get answer" ];
;; }
;; #+end_src
;;
;; Header for alternative file type:
;;
;; #+begin_src mscgen :file ex2.svg :filetype svg

;; This differs from most standard languages in that
;;
;; 1) there is no such thing as a "session" in mscgen
;; 2) we are generally only going to return results of type "file"
;; 3) we are adding the "file" and "filetype" header arguments
;; 4) there are no variables

;;; Code:
(require 'ob)

(defvar org-babel-default-header-args:mscgen
  '((:results . "file") (:exports . "results"))
  "Default arguments to use when evaluating a mscgen source block.")

(defun org-babel-execute:mscgen (body params)

    ;; the table is big and spans multiple pages, the text box could
    ;; overflow.  In this case, the following attribute will come
    ;; handy.

    ;; ,---- From OpenDocument-v1.1.pdf
    ;; | 15.27.28 Overflow behavior
    ;; |
    ;; | For text boxes contained within text document, the
    ;; | style:overflow-behavior property specifies the behavior of text
    ;; | boxes where the containing text does not fit into the text
    ;; | box.
    ;; |
    ;; | If the attribute's value is clip, the text that does not fit
    ;; | into the text box is not displayed.
    ;; |
    ;; | If the attribute value is auto-create-new-frame, a new frame
    ;; | will be created on the next page, with the same position and
    ;; | dimensions of the original frame.
    ;; |
    ;; | If the style:overflow-behavior property's value is
    ;; | auto-create-new-frame and the text box has a minimum width or
    ;; | height specified, then the text box will grow until the page
    ;; | bounds are reached before a new frame is created.
    ;; `----

    ;; Unfortunately, LibreOffice-3.4.6 doesn't honor
    ;; auto-create-new-frame property and always resorts to clipping
    ;; the text box.  This results in table being truncated.

    ;; So we solve the problem the hard (and fun) way using list
    ;; continuations.

    ;; The problem only becomes more interesting if you take in to
    ;; account the following facts:
    ;;
    ;; - Description lists are simulated as plain lists.
    ;; - Low-level headlines can be listified.
    ;; - In Org-mode, a table can occur not only as a regular list
    ;;   item, but also within description lists and low-level
    ;;   headlines.

;;   - 1.1
;;   - 1.2
;;   - 1.3
;; - Row 2

;;
;; Note that org-tables are NOT multi-line and each line is mapped to

;;; Commentary:
;;
;; This library implements a Texinfo back-end for Org generic
;; exporter.
;;
;; To test it, run
;;
;;   M-: (org-export-to-buffer 'texinfo "*Test Texinfo*") RET
;;
;; in an Org mode buffer then switch to the buffer to see the Texinfo
;; export.  See ox.el for more details on how this exporter works.
;;

;; It introduces nine new buffer keywords: "TEXINFO_CLASS",
;; "TEXINFO_FILENAME", "TEXINFO_HEADER", "TEXINFO_POST_HEADER",
;; "TEXINFO_DIR_CATEGORY", "TEXINFO_DIR_TITLE", "TEXINFO_DIR_DESC"
;; "SUBTITLE" and "SUBAUTHOR".

;;
;; It introduces 1 new headline property keywords:
;; "TEXINFO_MENU_TITLE" for optional menu titles.
;;
;; To include inline code snippets (for example for generating @kbd{}
;; and @key{} commands), the following export-snippet keys are
;; accepted:
;;
;;     texinfo
;;     info
;;
;; You can add them for export snippets via any of the below:
;;
;;    (add-to-list 'org-export-snippet-translation-alist
;;                 '("info" . "texinfo"))

The sectioning structure

The sectioning structure of the class is given by the elements

of strings is specified.  A %s formatter is mandatory in each
section string and will be replaced by the title of the section.

Instead of a list of sectioning commands, you can also specify
a function name.  That function will be called with two
parameters, the \(reduced) level of the headline, and a predicate
non-nil when the headline should be numbered.  It must return
a format string in which the section title will be added."

;;; Commentary:
;;
;; This file implements links to database entries in BibTeX files.
;; Instead of defining a special link prefix, it uses the normal file
;; links combined with a custom search mechanism to find entries
;; by reference key.  And it constructs a nice description tag for
;; the link that contains the author name, the year and a short title.
;;
;; It also stores detailed information about the entry so that
;; capture templates can access and enter this information easily.
;;
;; The available properties for each entry are listed here:
;;
;; :author        :publisher      :volume      :pages
;; :editor        :url            :number      :journal
;; :title         :year           :series      :address
;; :booktitle     :month          :annote      :abstract
;; :key           :btype
;;
;; Here is an example of a capture template that use some of this
;; information (:author :year :title :journal :pages):
;;
;; (setq org-capture-templates
;;   '((?b "* READ %?\n\n%a\n\n%:author (%:year): %:title\n   \
;;          In %:journal, %:pages.")))
;;
;; Let's say you want to capture this BibTeX entry:
;;
;; @Article{dolev83,
;;   author = 	 {Danny Dolev and Andrew C. Yao},
;;   title = 	 {On the security of public-key protocols},
;;   journal = 	 {IEEE Transaction on Information Theory},
;;   year = 	 1983,
;;   volume =	 2,
;;   number =	 29,
;;   pages =	 {198--208},
;;   month =	 {Mars}
;; }
;;
;; M-x `org-capture' on this entry will produce this buffer:
;;
;; =====================================================================
;; * READ <== [point here]
;;
;; [[file:file.bib::dolev83][Dolev & Yao 1983: security of public key protocols]]
;;
;; Danny Dolev and Andrew C. Yao (1983): On the security of public-key protocols
;; In IEEE Transaction on Information Theory, 198--208.
;; =====================================================================
;;
;; Additionally, the following functions are now available for storing
;; bibtex entries within Org-mode documents.
;;
;; - Run `org-bibtex' to export the current file to a .bib.
;;
;; - Run `org-bibtex-check' or `org-bibtex-check-all' to check and
;;   fill in missing field of either the current, or all headlines
;;
;; - Run `org-bibtex-create' to add a bibtex entry
;;
;; - Use `org-bibtex-read' to read a bibtex entry after `point' or in
;;   the active region, then call `org-bibtex-write' in a .org file to
;;   insert a heading for the read bibtex entry
;;
;; - All Bibtex information is taken from the document compiled by
;;   Andrew Roberts from the Bibtex manual, available at
;;   http://www.andy-roberts.net/res/writing/latex/bibentries.pdf
;;
;;; History:
;;
;; The link creation part has been part of Org-mode for a long time.
;;
;; Creating better capture template information was inspired by a request
;; of Austin Frank: http://article.gmane.org/gmane.emacs.orgmode/4112
;; and then implemented by Bastien Guerry.
;;
;; Eric Schulte eventually added the functions for translating between
;; Org-mode headlines and Bibtex entries, and for fleshing out the Bibtex
;; fields of existing Org-mode headlines.
;;
;; Org-mode loads this module by default - if this is not what you want,
;; configure the variable `org-modules'.

;;; Commentary:

;; This library enables the use of PicoLisp in the multi-language
;; programming framework Org-Babel.  PicoLisp is a minimal yet
;; fascinating lisp dialect and a highly productive application
;; framework for web-based client-server applications on top of
;; object-oriented databases.  A good way to learn PicoLisp is to first
;; read Paul Grahams essay "The hundred year language"
;; (http://www.paulgraham.com/hundred.html) and then study the various
;; documents and essays published in the PicoLisp wiki
;; (http://picolisp.com/5000/-2.html). PicoLisp is included in some
;; GNU/Linux Distributions, and can be downloaded here:
;; http://software-lab.de/down.html.  It ships with a picolisp-mode and
;; a inferior-picolisp-mode for Emacs (to be found in the /lib/el/
;; directory).

;; Although it might seem more natural to use Emacs Lisp for most
;; Lisp-based programming tasks inside Org-Mode, an Emacs library
;; written in Emacs Lisp, PicoLisp has at least two outstanding
;; features that make it a valuable addition to Org-Babel:

;; PicoLisp _is_ an object-oriented database with a Prolog-based query
;; language implemented in PicoLisp (Pilog). Database objects are
;; first-class members of the language.

;; PicoLisp is an extremely productive framework for the development
;; of interactive web-applications (on top of a database).

SECURITY CONSIDERATIONS:

Note that, when Org runs the encryption commands, the password could
be visible briefly on your system with the `ps' command.  So this method is
only intended to keep the files secure on the server, not on your own machine.

Also, if you set this variable in an init file (.emacs or .emacs.d/init.el

  "Parse the entry at point for shortcuts and expand them.
These shortcuts are meant for fast and easy typing on the limited
keyboards of a mobile device.  Below we show a list of the shortcuts
currently implemented.

The entry is expected to contain an inactive time stamp indicating when
the entry was created.  When setting dates and
times (for example for deadlines), the time strings are interpreted
relative to that creation date.
Abbreviations are expected to take up entire lines, just because it is so
easy to type RET on a mobile device.  Abbreviations start with one or two
letters, followed immediately by a dot and then additional information.
Generally the entire shortcut line is removed after action have been taken.
Time stamps will be constructed using `org-read-date'.  So for example a
line \"dd. 2tue\" will set a deadline on the second Tuesday after the
creation date.

Here are the shortcuts currently implemented:

dd. string             set deadline
ss. string             set scheduling
tt. string             set time tamp, here.
ti. string             set inactive time

tg. tag1 tag2 tag3     set all these tags, change case where necessary
td. kwd                set this todo keyword, change case where necessary

;;; 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.
;;
;; A list of recent changes can be found at

(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 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 in Emacs 23 or later only."

used to be an alias for `org-export-with-sub-superscripts' in
Org <8.0, it is not anymore.

When this option is turned on, you can use TeX-like syntax for
sub- and superscripts within the buffer.  Several characters after
\"_\" or \"^\" will be considered as a single item - so grouping
with {} is normally not needed.  For example, the following things
will be parsed as single sub- or superscripts:

 10^24   or   10^tau     several digits will be considered 1 item.
 10^-12  or   10^-tau    a leading sign with digits or a word
 x^2-y^3                 will be read as x^2 - y^3, because items are
			 terminated by almost any nonword/nondigit char.
 x_{i^2} or   x^(2-i)    braces or parenthesis do grouping.

Still, ambiguity is possible.  So when in doubt, use {} to enclose
the sub/superscript.  If you set this variable to the symbol `{}',
the braces are *required* in order to trigger interpretations as
sub/superscript.  This can be helpful in documents that need \"_\"
frequently in plain text."

                          (\"\\(?:xhtml\\|html\\)\" . \"firefox %s\")
                          to open *.html and *.xhtml with firefox.

               - Regular expression which contains (non-shy) groups:
                 Match links where the whole link, including \"::\", and
                 anything after that, matches the regexp.
                 In a custom command string, %1, %2, etc. are replaced with
                 the parts of the link that were matched by the groups.
                 For backwards compatibility, if a command string is given
                 that does not use any of the group matches, this case is
                 handled identically to the second one (i.e. match against
                 file name only).
                 In a custom lisp form, you can access the group matches with
                 (match-string n link).

                 Example: (\"\\.pdf::\\(\\d+\\)\\'\" . \"evince -p %1 %s\")
                     to open [[file:document.pdf::5]] with evince at page 5.

 `directory'   Matches a directory
 `remote'      Matches a remote file, accessible through tramp or efs.
               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
               \\[universal-argument] \\[universal-argument] 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'

(defcustom org-todo-keywords '((sequence "TODO" "DONE"))

\\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 bar, \"|\", 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

  "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.

\"~/org/datetree.org::datetree/* Finished Tasks\"
        The \"datetree/\" string is special, signifying to archive
        items to the datetree.  Items are placed in either the CLOSED
        date of the item, or the current date if there is no CLOSED date.
        The heading will be a subentry to the current date.  There doesn't
        need to be a heading, but there always needs to be a slash after
        datetree.  For example, to store archived items directly in the
        datetree, use \"~/org/datetree.org::datetree/\".

\"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

  "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

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 pressing 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
  (C-u TAB, same as S-TAB) also when called without prefix arg.
  But only if also the variable `org-cycle-global-at-bob' is t."

the previous location will be folded, which may not be what you
want.

This command works around this by showing a copy of the current

into the tree in that copy, use org-occur and incremental search
to find a location.  When pressing RET or `Q', the command
returns to the original buffer in which the visibility is still
unchanged.  After RET it will also jump to the location selected
in the indirect buffer and expose the headline hierarchy above.

you can call the function with a universal prefix argument.

When a valid repeater is given and the entry contains any time
stamps, the clones will become a sequence in time, with time
stamps in the subtree shifted for each clone produced.  If SHIFT

ID property of the original subtree is removed.

If the original subtree did contain time stamps with a repeater,
the following will happen:
- the repeater will be removed in each clone
- an additional clone will be produced, with the current, unshifted
  date(s) in the entry.
- the original entry will be placed *after* all the clones, with
  repeater intact.

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

The command prompts for the sorting type unless it has been given to the
function through the SORTING-TYPE argument, which needs to be a character,
\(?n ?N ?a ?A ?t ?T ?s ?S ?d ?D ?p ?P ?o ?O ?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.
o   By order of TODO keywords.
t   By date/time, either the first active time stamp in the entry, or, if
    none exist, by the first inactive one.
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.

FOLLOW and EXPORT are two functions.

FOLLOW should take the link path as the single argument and do whatever
is necessary to follow the link, for example find a file or display
a mail message.

EXPORT should format the link path for export to one of the export formats.
It should be a function accepting three arguments:

  path    the path of the link, the text after the prefix (like \"http:\")
  desc    the description of the link, if any, or a description added by
          org-export-normalize-links if there is none
  format  the export format, a symbol like `html' or `latex' or `ascii'..

The function may use the FORMAT information to return different values
depending on the format.  The return value will be put literally into
the exported file.  If the return value is nil, this means Org should
do what it normally does with links which do not have EXPORT defined.

Org-mode has a built-in default for exporting links.  If you are happy with
this default, there is no need to define an export function for the link
type.  For a simple example of an export function, see `org-bbdb.el'."

Completion can be used to insert any of the link protocol prefixes like
http or ftp in use.

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.

be used as the default description."

These functions are called in turn with point at the location to

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

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-arg'.  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

At the target location, the entry is filed as a subitem of the target
heading.  Depending on `org-reverse-note-order', the new subitem will
either be the first or the last subitem.

If there is an active region, all entries in that region will be moved.
However, the region must fulfill the requirement that the first heading
is the first one sets the top-level of the moved text - at most siblings
below it are allowed.

With prefix arg GOTO, the command will only visit the target location
and not actually move anything.

With a double prefix arg \\[universal-argument] \\[universal-argument], \
go to the location where the last refiling operation has put the subtree.

With a numeric prefix argument of `2', refile to the running clock.

With a numeric prefix argument of `3', emulate `org-refile-keep'
being set to `t' and copy to the target location, don't move it.
Beware that keeping refiled entries may result in duplicated ID
properties.

RFLOC can be a refile location obtained in a different way.

MSG is a string to replace \"Refile\" in the default prompt with
another verb.  E.g. `org-copy' sets this parameter to \"Copy\".

See also `org-refile-use-outline-path' and `org-completion-use-ido'.

If you are using target caching (see `org-refile-use-cache'),
you have to clear the target cache in order to find new targets.
This can be done with a 0 prefix (`C-0 C-c C-w') or a triple
prefix argument (`C-u C-u C-u C-c C-w')."

This replaces every group tag in MATCH with a regexp tag search.
For example, a group tag \"Work\" defined as { Work : Lab Conf }
will be replaced like this:

   Work =>  {\\(?:Work\\|Lab\\|Conf\\)}
  +Work => +{\\(?:Work\\|Lab\\|Conf\\)}
  -Work => -{\\(?:Work\\|Lab\\|Conf\\)}

Replacing by a regexp preserves the structure of the match.
E.g., this expansion

  Work|Home => {\\(?:Work\\|Lab\\|Conf\\}|Home

will match anything tagged with \"Lab\" and \"Home\", or tagged
with \"Conf\" and \"Home\" or tagged with \"Work\" and \"home\".

When the optional argument SINGLE-AS-LIST is non-nil, MATCH is
assumed to be a single group tag, and the function will return
the list of tags in this group.

(defun org-map-entries (func &optional match scope &rest skip)
  "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
region  The entries within the active region, if any
region-start-level
        The entries within the active region, but only those at
        the same level than the first one.
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 a position, FUNC will not be
             called for that entry and search will continue from the
             position returned

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,
or to enter the second timestamp of a range, the default time is taken
from the existing stamp.  Furthermore, the command prefers the future,
so if you are giving a date where the year is not given, and the day-month
combination is already past in the current year, it will assume you
mean next year.  For details, see the manual.  A few examples:

  3-2-5         --> 2003-02-05
  feb 15        --> currentyear-02-15
  2/15          --> 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 after today
  -Tue          --> last Tuesday
  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 [hdwmy] 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.

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 ORG-WITH-TIME, the prompt will suggest to
also insert a time.  Note that when ORG-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."

for example currency specifications.  For example it will assume being in
inline math after \"$22.34\".  The LaTeX fragment formatter will only format

This command does many different things, depending on context:

- If a function in `org-ctrl-c-ctrl-c-hook' recognizes this location,
  this is what we do.

- If the cursor is on a statistics cookie, update it.

- If the cursor is in a headline, prompt for tags and insert them
  into the current line, aligned to `org-tags-column'.  When called
  with prefix arg, realign all tags in the current buffer.

- 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 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 current buffer is a capture buffer, close note and file it.

- If the cursor is on a <<>>, update radio targets and
  corresponding links in this buffer.

- If the cursor is on a numbered item in a plain list, renumber the
  ordered list.

- If the cursor is on a checkbox, toggle it.

- If the cursor is on a code block, evaluate it.  The variable
  `org-confirm-babel-evaluate' can be used to control prompting
  before code block evaluation, by default every code block
  evaluation requires confirmation.  Code block evaluation can be
  inhibited by setting `org-babel-no-eval-on-ctrl-c-ctrl-c'."

;; This library implements a Man back-end for Org generic exporter.
;;
;; To test it, run
;;
;;   M-: (org-export-to-buffer 'man "*Test Man*") RET
;;
;; in an org-mode buffer then switch to the buffer to see the Man
;; export.  See ox.el for more details on how this exporter works.
;;
;; It introduces one new buffer keywords:
;; "MAN_CLASS_OPTIONS".

;;; Commentary:
;;
;;  This module allows to create and change entries in an Org-mode
;;  file triggered by items in an RSS feed.  The basic functionality is
;;  geared toward simply adding new items found in a feed as outline nodes
;;  to an Org file.  Using hooks, arbitrary actions can be triggered for
;;  new or changed items.
;;
;;  Selecting feeds and target locations
;;  ------------------------------------
;;
;;  This module is configured through a single variable, `org-feed-alist'.
;;  Here is an example, using a notes/tasks feed from reQall.com.
;;
;;    (setq org-feed-alist
;;          '(("ReQall"
;;             "http://www.reqall.com/user/feeds/rss/a1b2c3....."
;;             "~/org/feeds.org" "ReQall Entries")
;;
;;  With this setup, the command `M-x org-feed-update-all' will
;;  collect new entries in the feed at the given URL and create
;;  entries as subheadings under the "ReQall Entries" heading in the
;;  file "~/org/feeds.org".  Each feed should normally have its own
;;  heading - however see the `:drawer' parameter.
;;
;;  Besides these standard elements that need to be specified for each
;;  feed, keyword-value pairs can set additional options.  For example,
;;  to de-select transitional entries with a title containing
;;
;;                   "reQall is typing what you said",
;;
;;  you could use the `:filter' argument:
;;
;;    (setq org-feed-alist
;;          '(("ReQall"
;;             "http://www.reqall.com/user/feeds/rss/a1b2c3....."
;;             "~/org/feeds.org" "ReQall Entries"
;;             :filter my-reqall-filter)))
;;
;;    (defun my-reqall-filter (e)
;;       (if (string-match "reQall is typing what you said"
;;                         (plist-get e :title))
;;           nil
;;         e))
;;
;;  See the docstring for `org-feed-alist' for more details.
;;
;;
;;  Keeping track of previously added entries
;;  -----------------------------------------
;;
;;  Since Org allows you to delete, archive, or move outline nodes,
;;  org-feed.el needs to keep track of which feed items have been handled
;;  before, so that they will not be handled again.  For this, org-feed.el
;;  stores information in a special drawer, FEEDSTATUS, under the heading
;;  that received the input of the feed.  You should add FEEDSTATUS
;;  to your list of drawers in the files that receive feed input:
;;
;;       #+DRAWERS: PROPERTIES CLOCK LOGBOOK RESULTS FEEDSTATUS
;;
;;  Acknowledgments
;;  ---------------
;;
;;  org-feed.el is based on ideas by Brad Bozarth who implemented a
;;  similar mechanism using shell and awk scripts.

(defcustom org-feed-alist nil
  "Alist specifying RSS feeds that should create inputs for Org.
Each entry in this list specified an RSS feed tat should be queried
to create inbox items in Org.  Each entry is a list with the following items:

name         a custom name for this feed
URL          the Feed URL
file         the target Org file where entries should be listed
headline     the headline under which entries should be listed

Additional arguments can be given using keyword-value pairs.  Many of these
specify functions that receive one or a list of \"entries\" as their single
argument.  An entry is a property list that describes a feed item.  The
property list has properties for each field in the item, for example `:title'
for the `' field and `:pubDate' for the publication date.  In addition,
it contains the following properties:

`:item-full-text'   the full text in the <item> tag
`:guid-permalink'   t when the guid property is a permalink

Here are the keyword-value pair allows in `org-feed-alist'.

:drawer drawer-name
     The name of the drawer for storing feed information.  The default is
     \"FEEDSTATUS\".  Using different drawers for different feeds allows
     several feeds to target the same inbox heading.

:filter filter-function
     A function to select interesting entries in the feed.  It gets a single
     entry as parameter.  It should return the entry if it is relevant, or
     nil if it is not.

:template template-string
     The default action on new items in the feed is to add them as children
     under the headline for the feed.  The template describes how the entry
     should be formatted.  If not given, it defaults to
     `org-feed-default-template'.

:formatter formatter-function
     Instead of relying on a template, you may specify a function to format
     the outline node to be inserted as a child.  This function gets passed
     a property list describing a single feed item, and it should return a
     string that is a properly formatted Org outline node of level 1.

:new-handler function
     If adding new items as children to the outline is not what you want
     to do with new items, define a handler function that is called with
     a list of all new items in the feed, each one represented as a property
     list.  The handler should do what needs to be done, and org-feed will
     mark all items given to this handler as \"handled\", i.e. they will not
     be passed to this handler again in future readings of the feed.
     When the handler is called, point will be at the feed headline.

:changed-handler function
     This function gets passed a list of all entries that have been
     handled before, but are now still in the feed and have *changed*
     since last handled (as evidenced by a different sha1 hash).
     When the handler is called, point will be at the feed headline.

:parse-feed function
     This function gets passed a buffer, and should return a list
     of entries, each being a property list containing the
     `:guid' and `:item-full-text' keys.  The default is
     `org-feed-parse-rss-feed'; `org-feed-parse-atom-feed' is an
     alternative.

:parse-entry function
     This function gets passed an entry as returned by the parse-feed
     function, and should return the entry with interesting properties added.
     The default is `org-feed-parse-rss-entry'; `org-feed-parse-atom-entry'
     is an alternative."

references to source-code blocks, to force interpretation of a
cell's value as a string, prefix the identifier a \"$\" (e.g.,
\"$$2\" instead of \"$2\" or \"$@2$2\" instead of \"@2$2\").

NOTE: it is also possible to pass header arguments to the code
block.  In this case a table cell should hold the string value of
the header argument which can then be passed before all variables
as shown in the example below.

;;; Commentary:

;; Org-Babel support for evaluating haskell source code.  This one will
;; be sort of tricky because haskell programs must be compiled before
;; they can be run, but haskell code can also be run through an
;; interactive interpreter.
;;
;; For now lets only allow evaluation using the haskell interpreter.

;;; Requirements:

;; - haskell-mode :: http://www.iro.umontreal.ca/~monnier/elisp/#haskell-mode
;;
;; - inf-haskell :: http://www.iro.umontreal.ca/~monnier/elisp/#haskell-mode
;;
;; - (optionally) lhs2tex :: http://people.cs.uu.nl/andres/lhs2tex/

;;; Commentary:

;; This file implements links to open files in doc-view-mode.
;; Org-mode loads this module by default - if this is not what you want,
;; configure the variable `org-modules'.

;; The links take the form
;;
;;    docview:<file path>::<page number>
;;
;; for example: [[docview:~/.elisp/org/doc/org.pdf::1][Org-Mode Manual]]
;;
;; Autocompletion for inserting links is supported; you will be
;; prompted for a file and a page number.
;;
;; If you use org-store-link in a doc-view mode buffer, the stored
;; link will point to the current page.

;; This file implements copying HTML content from a w3m buffer and
;; transforming the text on the fly so that it can be pasted into
;; an org-mode buffer with hot links.  It will also work for regions
;; in gnus buffers that have been washed with w3m.

;;; Commentary:

;; Right now this is just a set of functions to play with.  It depends
;; on the epg library.  Here's how you would use it:
;;
;; 1. To mark an entry for encryption, tag the heading with "crypt".
;;    You can change the tag to any complex tag matching string by
;;    setting the `org-crypt-tag-matcher' variable.
;;
;; 2. Set the encryption key to use in the `org-crypt-key' variable,
;;    or use `M-x org-set-property' to set the property CRYPTKEY to
;;    any address in your public keyring.  The text of the entry (but
;;    not its properties or headline) will be encrypted for this user.
;;    For them to read it, the corresponding secret key must be
;;    located in the secret key ring of the account where you try to
;;    decrypt it.  This makes it possible to leave secure notes that
;;    only the intended recipient can read in a shared-org-mode-files
;;    scenario.
;;    If the key is not set, org-crypt will default to symmetric encryption.
;;
;; 3. To later decrypt an entry, use `org-decrypt-entries' or
;;    `org-decrypt-entry'.  It might be useful to bind this to a key,
;;    like C-c C-/.  I hope that in the future, C-c C-r can be might
;;    overloaded to also decrypt an entry if it's encrypted, since
;;    that fits nicely with the meaning of "reveal".
;;
;; 4. To automatically encrypt all necessary entries when saving a
;;    file, call `org-crypt-use-before-save-magic' after loading
;;    org-crypt.el.

;;; Commentary:
;;
;; This library implements a generic export engine for Org, built on
;; its syntactical parser: Org Elements.
;;
;; Besides that parser, the generic exporter is made of three distinct
;; parts:
;;
;; - The communication channel consists in a property list, which is
;;   created and updated during the process.  Its use is to offer
;;   every piece of information, would it be about initial environment
;;   or contextual data, all in a single place.  The exhaustive list
;;   of properties is given in "The Communication Channel" section of
;;   this file.
;;
;; - The transcoder walks the parse tree, ignores or treat as plain
;;   text elements and objects according to export options, and
;;   eventually calls back-end specific functions to do the real
;;   transcoding, concatenating their return value along the way.
;;
;; - The filter system is activated at the very beginning and the very
;;   end of the export process, and each time an element or an object
;;   has been converted.  It is the entry point to fine-tune standard
;;   output from back-end transcoders.  See "The Filter System"
;;   section for more information.
;;
;; The core function is `org-export-as'.  It returns the transcoded
;; buffer as a string.
;;
;; An export back-end is defined with `org-export-define-backend'.
;; This function can also support specific buffer keywords, OPTION
;; keyword's items and filters.  Refer to function's documentation for
;; more information.
;;
;; If the new back-end shares most properties with another one,
;; `org-export-define-derived-backend' can be used to simplify the
;; process.
;;
;; Any back-end can define its own variables.  Among them, those
;; customizable should belong to the `org-export-BACKEND' group.
;;
;; Tools for common tasks across back-ends are implemented in the
;; following part of the file.
;;
;; Then, a wrapper macro for asynchronous export,
;; `org-export-async-start', along with tools to display results. are
;; given in the penultimate part.
;;
;; Eventually, a dispatcher (`org-export-dispatch') for standard
;; back-ends is provided in the last one.

sub- and superscripts and see them exported correctly.

You can also set the option with #+OPTIONS: ^:t

Several characters after \"_\" or \"^\" will be considered as a
single item - so grouping with {} is normally not needed.  For
example, the following things will be parsed as single sub- or
superscripts:

 10^24   or   10^tau     several digits will be considered 1 item.
 10^-12  or   10^-tau    a leading sign with digits or a word
 x^2-y^3                 will be read as x^2 - y^3, because items are
			 terminated by almost any nonword/nondigit char.
 x_{i^2} or   x^(2-i)    braces or parenthesis do grouping.

Still, ambiguity is possible.  So when in doubt, use {} to enclose
the sub/superscript.  If you set this variable to the symbol `{}',
the braces are *required* in order to trigger interpretations as
sub/superscript.  This can be helpful in documents that need \"_\"

TRANSCODERS is an alist between object or element types and
functions handling them.

These functions should return a string without any trailing
space, or nil.  They must accept three arguments: the object or
element itself, its contents or nil when it isn't recursive and
the property list used as a communication channel.

Contents, when not nil, are stripped from any global indentation
\(although the relative one is preserved).  They also always end
with a single newline character.

If, for a given type, no function is found, that element or
object type will simply be ignored, along with any blank line or
white space at its end.  The same will happen if the function
returns the nil value.  If that function returns the empty
string, the type will be ignored, but the blank lines or white
spaces will be kept.

In addition to element and object types, one function can be
associated to the `template' (or `inner-template') symbol and
another one to the `plain-text' symbol.

The former returns the final transcoded string, and can be used
to add a preamble and a postamble to document's body.  It must
accept two arguments: the transcoded string and the property list
containing export options.  A function associated to `template'
will not be applied if export has option \"body-only\".
A function associated to `inner-template' is always applied.

The latter, when defined, is to be called on every text not
recognized as an element or an object.  It must accept two
arguments: the text string and the information channel.  It is an
appropriate place to protect special chars relative to the
back-end.

BODY can start with pre-defined keyword arguments.  The following
keywords are understood:

  :export-block

    String, or list of strings, representing block names that
    will not be parsed.  This is used to specify blocks that will
    contain raw code specific to the back-end.  These blocks
    still have to be handled by the relative `export-block' type
    translator.

  :filters-alist

    Alist between filters and function, or list of functions,
    specific to the back-end.  See `org-export-filters-alist' for
    a list of all allowed filters.  Filters defined here
    shouldn't make a back-end test, as it may prevent back-ends
    derived from this one to behave properly.

  :menu-entry

    Menu entry for the export dispatcher.  It should be a list
    like:

      '(KEY DESCRIPTION-OR-ORDINAL ACTION-OR-MENU)

    where :

      KEY is a free character selecting the back-end.

      DESCRIPTION-OR-ORDINAL is either a string or a number.

      If it is a string, is will be used to name the back-end in
      its menu entry.  If it is a number, the following menu will
      be displayed as a sub-menu of the back-end with the same
      KEY.  Also, the number will be used to determine in which
      order such sub-menus will appear (lowest first).

      ACTION-OR-MENU is either a function or an alist.

      If it is an action, it will be called with four
      arguments (booleans): ASYNC, SUBTREEP, VISIBLE-ONLY and
      BODY-ONLY.  See `org-export-as' for further explanations on
      some of them.

      If it is an alist, associations should follow the
      pattern:

        '(KEY DESCRIPTION ACTION)

      where KEY, DESCRIPTION and ACTION are described above.

    Valid values include:

      '(?m \"My Special Back-end\" my-special-export-function)

      or

      '(?l \"Export to LaTeX\"
           \(?p \"As PDF file\" org-latex-export-to-pdf)
           \(?o \"As PDF file and open\"
               \(lambda (a s v b)
                 \(if a (org-latex-export-to-pdf t s v b)
                   \(org-open-file
                    \(org-latex-export-to-pdf nil s v b)))))))

      or the following, which will be added to the previous
      sub-menu,

      '(?l 1
          \((?B \"As TEX buffer (Beamer)\" org-beamer-export-as-latex)
           \(?P \"As PDF file (Beamer)\" org-beamer-export-to-pdf)))

  :options-alist

    Alist between back-end specific properties introduced in
    communication channel and how their value are acquired.  See
    `org-export-options-alist' for more information about
    structure of the values."

    Alist of element and object types and transcoders that will

    Refer to `org-export-define-backend' for detailed information
    about transcoders.

As an example, here is how one could define \"my-latex\" back-end

;;; The Communication Channel
;;
;; During export process, every function has access to a number of
;; properties.  They are of two types:
;;
;; 1. Environment options are collected once at the very beginning of
;;    the process, out of the original buffer and configuration.
;;    Collecting them is handled by `org-export-get-environment'
;;    function.
;;
;;    Most environment options are defined through the
;;    `org-export-options-alist' variable.
;;
;; 2. Tree properties are extracted directly from the parsed tree,
;;    just before export, by `org-export-collect-tree-properties'.
;;
;; Here is the full list of properties available during transcode
;; process, with their category and their value type.
;;
;; + `:author' :: Author's name.
;;   - category :: option
;;   - type :: string
;;
;; + `:back-end' :: Current back-end used for transcoding.
;;   - category :: tree
;;   - type :: symbol
;;
;; + `:creator' :: String to write as creation information.
;;   - category :: option
;;   - type :: string
;;
;; + `:date' :: String to use as date.

;;   - type :: string
;;
;; + `:description' :: Description text for the current data.
;;   - category :: option
;;   - type :: string
;;
;; + `:email' :: Author's email.
;;   - category :: option
;;   - type :: string
;;
;; + `:exclude-tags' :: Tags for exclusion of subtrees from export
;;      process.
;;   - category :: option
;;   - type :: list of strings
;;
;; + `:export-options' :: List of export options available for current
;;      process.

;;   - category :: option
;;   - type :: list of strings
;;
;; + `:footnote-definition-alist' :: Alist between footnote labels and
;;      their definition, as parsed data.  Only non-inlined footnotes
;;      are represented in this alist.  Also, every definition isn't
;;      guaranteed to be referenced in the parse tree.  The purpose of
;;      this property is to preserve definitions from oblivion
;;      (i.e. when the parse tree comes from a part of the original
;;      buffer), it isn't meant for direct use in a back-end.  To
;;      retrieve a definition relative to a reference, use
;;      `org-export-get-footnote-definition' instead.
;;   - category :: option
;;   - type :: alist (STRING . LIST)
;;
;; + `:headline-levels' :: Maximum level being exported as an

;;      headlines in the parse tree, not necessarily with their
;;      actual level.
;;   - category :: option
;;   - type :: integer
;;
;; + `:headline-offset' :: Difference between relative and real level
;;      of headlines in the parse tree.  For example, a value of -1
;;      means a level 2 headline should be considered as level
;;      1 (cf. `org-export-get-relative-level').
;;   - category :: tree
;;   - type :: integer

;;;; Environment Options
;;
;; Environment options encompass all parameters defined outside the

;; - Global variables,
;; - Buffer's attributes,
;; - Options keyword symbols,
;; - Buffer keywords,
;; - Subtree properties.
;;
;; The central internal function with regards to environment options
;; is `org-export-get-environment'.  It updates global variables with
;; "#+BIND:" keywords, then retrieve and prioritize properties from
;; the different sources.
;;
;;  The internal functions doing the retrieval are:
;;  `org-export--get-global-options',
;;  `org-export--get-buffer-attributes',
;;  `org-export--parse-option-keyword',
;;  `org-export--get-subtree-options' and
;;  `org-export--get-inbuffer-options'
;;
;; Also, `org-export--list-bound-variables' collects bound variables
;; along with their value in order to set them as buffer local
;; variables later in the process.

;;; The Transcoder
;;
;; `org-export-data' reads a parse tree (obtained with, i.e.
;; `org-element-parse-buffer') and transcodes it into a specified
;; back-end output.  It takes care of filtering out elements or
;; objects according to export options and organizing the output blank
;; lines and white space are preserved.  The function memoizes its
;; results, so it is cheap to call it within transcoders.
;;
;; It is possible to modify locally the back-end used by
;; `org-export-data' or even use a temporary back-end by using
;; `org-export-data-with-backend'.
;;
;; Internally, three functions handle the filtering of objects and
;; elements during the export.  In particular,
;; `org-export-ignore-element' marks an element or object so future
;; parse tree traversals skip it, `org-export--interpret-p' tells which
;; elements or objects should be seen as real Org syntax and
;; `org-export-expand' transforms the others back into their original
;; shape
;;
;; `org-export-transcoder' is an accessor returning appropriate
;; translator function for a given element or object.

;;; The Filter System
;;
;; Filters allow end-users to tweak easily the transcoded output.
;; They are the functional counterpart of hooks, as every filter in
;; a set is applied to the return value of the previous one.
;;
;; Every set is back-end agnostic.  Although, a filter is always
;; called, in addition to the string it applies to, with the back-end
;; used as argument, so it's easy for the end-user to add back-end
;; specific filters in the set.  The communication channel, as
;; a plist, is required as the third argument.
;;
;; From the developer side, filters sets can be installed in the
;; process with the help of `org-export-define-backend', which
;; internally stores filters as an alist.  Each association has a key
;; among the following symbols and a function or a list of functions
;; as value.
;;
;; - `:filter-options' applies to the property list containing export
;;   options.  Unlike to other filters, functions in this list accept
;;   two arguments instead of three: the property list containing
;;   export options and the back-end.  Users can set its value through
;;   `org-export-filter-options-functions' variable.
;;
;; - `:filter-parse-tree' applies directly to the complete parsed
;;   tree.  Users can set it through
;;   `org-export-filter-parse-tree-functions' variable.
;;
;; - `:filter-final-output' applies to the final transcoded string.
;;   Users can set it with `org-export-filter-final-output-functions'
;;   variable
;;
;; - `:filter-plain-text' applies to any string not recognized as Org
;;   syntax.  `org-export-filter-plain-text-functions' allows users to
;;   configure it.
;;
;; - `:filter-TYPE' applies on the string returned after an element or
;;   object of type TYPE has been transcoded.  A user can modify
;;   `org-export-filter-TYPE-functions'
;;
;; All filters sets are applied with
;; `org-export-filter-apply-functions' function.  Filters in a set are
;; applied in a LIFO fashion.  It allows developers to be sure that
;; their filters will be applied first.
;;
;; Filters properties are installed in communication channel with
;; `org-export-install-filters' function.
;;
;; Eventually, two hooks (`org-export-before-processing-hook' and
;; `org-export-before-parsing-hook') are run at the beginning of the
;; export process and just before parsing to allow for heavy structure
;; modifications.

;; `org-export--copy-to-kill-ring-p' determines if output of these
;; function should be added to kill ring.
;;
;; Note that `org-export-as' doesn't really parse the current buffer,
;; but a copy of it (with the same buffer-local variables and
;; visibility), where macros and include keywords are expanded and
;; Babel blocks are executed, if appropriate.
;; `org-export-with-buffer-copy' macro prepares that copy.
;;
;; File inclusion is taken care of by
;; `org-export-expand-include-keyword' and
;; `org-export--prepare-file-contents'.  Structure wise, including
;; a whole Org file in a buffer often makes little sense.  For
;; example, if the file contains a headline and the include keyword
;; was within an item, the item should contain the headline.  That's
;; why file inclusion should be done before any structure can be
;; associated to the file, that is before parsing.
;;
;; `org-export-insert-default-template' is a command to insert
;; a default template (or a back-end specific template) at point or in

;;; Asynchronous Export
;;
;; `org-export-async-start' is the entry point for asynchronous
;; export.  It recreates current buffer (including visibility,
;; narrowing and visited file) in an external Emacs process, and
;; evaluates a command there.  It then applies a function on the
;; returned results in the current process.
;;
;; At a higher level, `org-export-to-buffer' and `org-export-to-file'
;; allow to export to a buffer or a file, asynchronously or not.
;;
;; `org-export-output-file-name' is an auxiliary function meant to be
;; used with `org-export-to-file'.  With a given extension, it tries
;; to provide a canonical file name to write export output to.
;;
;; Asynchronously generated results are never displayed directly.
;; Instead, they are stored in `org-export-stack-contents'.  They can
;; then be retrieved by calling `org-export-stack'.
;;
;; Export Stack is viewed through a dedicated major mode
;;`org-export-stack-mode' and tools: `org-export-stack-refresh',
;;`org-export-stack-delete', `org-export-stack-view' and
;;`org-export-stack-clear'.
;;
;; For back-ends, `org-export-add-to-stack' add a new source to stack.
;; It should be used whenever `org-export-async-start' is called.

;;; Commentary:

;; This file implements links to BBDB database entries from within Org-mode.
;; Org-mode loads this module by default - if this is not what you want,
;; configure the variable `org-modules'.

;; It also implements an interface (based on Ivar Rummelhoff's
;; bbdb-anniv.el) for those org-mode users, who do not use the diary
;; but who do want to include the anniversaries stored in the BBDB
;; into the org-agenda.  If you already include the `diary' into the
;; agenda, you might want to prefer to include the anniversaries in
;; the diary using bbdb-anniv.el.
;;
;; Put the following in /somewhere/at/home/diary.org and make sure
;; that this file is in `org-agenda-files`
;;
;; %%(org-bbdb-anniversaries)
;;
;; For example my diary.org looks like:
;; * Anniversaries
;; #+CATEGORY: Anniv
;; %%(org-bbdb-anniversaries)
;;
;;
;; To add an anniversary to a BBDB record, press `C-o' in the record.
;; You will be prompted for the field name, in this case it must be
;; "anniversary".  If this is the first time you are using this field,
;; you need to confirm that it should be created.
;;
;; The format of an anniversary field stored in BBDB is the following
;; (items in {} are optional):
;;
;;     YYYY-MM-DD{ CLASS-OR-FORMAT-STRING}
;;     {\nYYYY-MM-DD CLASS-OR-FORMAT-STRING}...
;;
;; CLASS-OR-FORMAT-STRING is one of two things:
;;
;;  - an identifier for a class of anniversaries (eg. birthday or
;;    wedding) from `org-bbdb-anniversary-format-alist' which then
;;    defines the format string for this class
;;  - the (format) string displayed in the diary.
;;
;; You can enter multiple anniversaries for a single BBDB record by
;; separating them with a newline character.  At the BBDB prompt for
;; the field value, type `C-q C-j' to enter a newline between two
;; anniversaries.
;;
;; If you omit the CLASS-OR-FORMAT-STRING entirely, it defaults to the
;; value of `org-bbdb-default-anniversary-format' ("birthday" by
;; default).
;;
;; The substitutions in the format string are (in order):
;;  - the name of the record containing this anniversary
;;  - the number of years
;;  - an ordinal suffix (st, nd, rd, th) for the year
;;
;; See the documentation of `org-bbdb-anniversary-format-alist' for
;; further options.
;;
;; Example
;;
;;       1973-06-22
;;       20??-??-?? wedding
;;       1998-03-12 %s created bbdb-anniv.el %d years ago
;;
;; From Org's agenda, you can use `C-c C-o' to jump to the BBDB
;; link from which the entry at point originates.

;;; Commentary:

;; Org-Babel support for evaluating sql source code.
;; (see also ob-sqlite.el)
;;
;; SQL is somewhat unique in that there are many different engines for
;; the evaluation of sql (Mysql, PostgreSQL, etc...), so much of this
;; file will have to be implemented engine by engine.
;;
;; Also SQL evaluation generally takes place inside of a database.
;;
;; Header args used:
;; - engine
;; - cmdline
;; - dbhost
;; - dbuser
;; - dbpassword
;; - database
;; - colnames (default, nil, means "yes")
;; - result-params
;; - out-file
;; The following are used but not really implemented for SQL:
;; - colname-names
;; - rownames
;; - rowname-names
;;
;; TODO:
;;
;; - support for sessions
;; - support for more engines (currently only supports mysql)
;; - what's a reasonable way to drop table data into SQL?
;;

;;; Commentary:
;;
;; Intercept calls from emacsclient to trigger custom actions.
;;
;; This is done by advising `server-visit-files' to scan the list of filenames
;; for `org-protocol-the-protocol' and sub-protocols defined in
;; `org-protocol-protocol-alist' and `org-protocol-protocol-alist-default'.
;;
;; Any application that supports calling external programs with an URL
;; as argument may be used with this functionality.
;;
;;
;; Usage:
;; ------
;;
;;   1.) Add this to your init file (.emacs probably):
;;
;;       (add-to-list 'load-path "/path/to/org-protocol/")
;;       (require 'org-protocol)
;;
;;   3.) Ensure emacs-server is up and running.
;;   4.) Try this from the command line (adjust the URL as needed):
;;
;;       $ emacsclient \
;;         org-protocol://store-link://http:%2F%2Flocalhost%2Findex.html/The%20title
;;
;;   5.) Optionally add custom sub-protocols and handlers:
;;
;;       (setq org-protocol-protocol-alist
;;             '(("my-protocol"
;;                :protocol "my-protocol"
;;                :function my-protocol-handler-function)))
;;
;;       A "sub-protocol" will be found in URLs like this:
;;
;;           org-protocol://sub-protocol://data
;;
;; If it works, you can now setup other applications for using this feature.
;;
;;
;; As of March 2009 Firefox users follow the steps documented on
;; http://kb.mozillazine.org/Register_protocol, Opera setup is described here:
;; http://www.opera.com/support/kb/view/535/
;;
;;
;; Documentation
;; -------------
;;
;; org-protocol.el comes with and installs handlers to open sources of published
;; online content, store and insert the browser's URLs and cite online content
;; by clicking on a bookmark in Firefox, Opera and probably other browsers and
;; applications:
;;
;;   * `org-protocol-open-source' uses the sub-protocol \"open-source\" and maps
;;     URLs to local filenames defined in `org-protocol-project-alist'.
;;
;;   * `org-protocol-store-link' stores an Org-link (if Org-mode is present) and
;;     pushes the browsers URL to the `kill-ring' for yanking.  This handler is
;;     triggered through the sub-protocol \"store-link\".
;;
;;   * Call `org-protocol-capture' by using the sub-protocol \"capture\".  If
;;     Org-mode is loaded, Emacs will pop-up a capture buffer and fill the
;;     template with the data provided.  I.e. the browser's URL is inserted as an
;;     Org-link of which the page title will be the description part.  If text
;;     was select in the browser, that text will be the body of the entry.
;;
;; You may use the same bookmark URL for all those standard handlers and just
;; adjust the sub-protocol used:
;;
;;     location.href='org-protocol://sub-protocol://'+
;;           encodeURIComponent(location.href)+'/'+
;;           encodeURIComponent(document.title)+'/'+
;;           encodeURIComponent(window.getSelection())
;;
;; The handler for the sub-protocol \"capture\" detects an optional template
;; char that, if present, triggers the use of a special template.
;; Example:
;;
;;     location.href='org-protocol://sub-protocol://x/'+ ...
;;
;;  use template ?x.
;;
;; Note, that using double slashes is optional from org-protocol.el's point of
;; view because emacsclient squashes the slashes to one.

  "Map URLs to local filenames for `org-protocol-open-source' (open-source).

Each element of this list must be of the form:

  (module-name :property value property: value ...)

where module-name is an arbitrary name.  All the values are strings.

Possible properties are:

  :online-suffix     - the suffix to strip from the published URLs
  :working-suffix    - the replacement for online-suffix
  :base-url          - the base URL, e.g. http://www.example.com/project/
                       Last slash required.
  :working-directory - the local working directory.  This is, what base-url will
                       be replaced with.
  :redirects         - A list of cons cells, each of which maps a regular
                       expression to match to a path relative to :working-directory.

Example:

   (setq org-protocol-project-alist
       '((\"http://orgmode.org/worg/\"
          :online-suffix \".php\"
          :working-suffix \".org\"

          :working-directory \"/home/user/org/\"
          :rewrites ((\"org/?$\" . \"index.php\")))))

   The last line tells `org-protocol-open-source' to open
   /home/user/org/index.php, if the URL cannot be mapped to an existing
   file, and ends with either \"org\" or \"org/\".

`org-protocol-create-for-org' to help you filling this variable with valid contents."

  "Register custom handlers for org-protocol.

Each element of this list must be of the form:

  (module-name :protocol protocol :function func :kill-client nil)

protocol - protocol to detect in a filename without trailing colon and slashes.
           See rfc1738 section 2.1 for more on this.
           If you define a protocol \"my-protocol\", `org-protocol-check-filename-for-protocol'
           will search filenames for \"org-protocol:/my-protocol:/\"
           and trigger your action for every match. `org-protocol' is defined in
           `org-protocol-the-protocol'.  Double and triple slashes are compressed
           to one by emacsclient.

function - function that handles requests with protocol and takes exactly one
           argument: the filename with all protocols stripped.  If the function
           returns nil, emacsclient and -server do nothing.  Any non-nil return
           value is considered a valid filename and thus passed to the server.

           `org-protocol.el provides some support for handling those filenames,
           if you stay with the conventions used for the standard handlers in
           `org-protocol-protocol-alist-default'.  See `org-protocol-split-data'.

kill-client - If t, kill the client immediately, once the sub-protocol is
           detected.  This is necessary for actions that can be interrupted by
           `C-g' to avoid dangling emacsclients.  Note, that all other command
           line arguments but the this one will be discarded, greedy handlers
           still receive the whole list of arguments though.

Here is an example:

  (setq org-protocol-protocol-alist

;;; Commentary:

;; This file contains the table editor and spreadsheet for Org-mode.

;; Watch out:  Here we are talking about two different kind of tables.
;; Most of the code is for the tables created with the Org-mode table editor.
;; Sometimes, we talk about tables created and edited with the table.el
;; Emacs package.  We call the former org-type tables, and the latter
;; table.el-type tables.

  "Wrap several fields in a column like a paragraph.
This is useful if you'd like to spread the contents of a field over several
lines, in order to keep the table compact.

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
line down.

If there is no region, but you specify a prefix ARG, the current field gets
blank, and the content is appended to the field above."

  "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 be 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.

(defun orgtbl-to-generic (table params &optional backend)
  "Convert the orgtbl-mode TABLE to some other format.
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.
A third optional argument BACKEND can be used to convert the content of
the cells using a specific export back-end.

For the generic converter, some parameters are obligatory: you need to
specify either :lfmt, or all of (:lstart :lend :sep).

Valid parameters are:

:splice     When set to t, return only table body lines, don't wrap
            them into :tstart and :tend.  Default is nil.  When :splice
            is non-nil, this also means that the exporter should not look
            for and interpret header and footer sections.

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

:sep        Separator between two fields
:remove-nil-lines Do not include lines that evaluate to nil.

Each in the following group may be either a string or a function
of no arguments returning a string:

:tstart     String to start the table.  Ignored when :splice is t.
:tend       String to end the table.  Ignored when :splice is t.
:lstart     String to start a new table line.
:llstart    String to start the last table line, defaults to :lstart.
:lend       String to end a table line
:llend      String to end the last table line, defaults to :lend.

Each in the following group may be a string, a function of one
argument (the field or line) returning a string, or a plist
mapping columns to either of the above:

:lfmt       Format for entire line, with enough %s to capture all fields.
            If this is present, :lstart, :lend, and :sep are ignored.
:llfmt      Format for the entire last line, defaults to :lfmt.
: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 :hllstart :hlend :hllend :hlsep :hlfmt :hllfmt :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.

This may be either a string or a function of two arguments:

: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."

;;; Commentary:

;; This file contains the code dealing with plain lists in Org-mode.

;; The core concept behind lists is their structure.  A structure is
;; a snapshot of the list, in the shape of a data tree (see
;; `org-list-struct').

;; Once the list structure is stored, it is possible to make changes
;; on it that will be mirrored to the real list or to get information
;; about the list, using accessors and methods provided in the
;; library.  Most of them require the use of one or two helper
;; functions, namely `org-list-parents-alist' and
;; `org-list-prevs-alist'.

;; Structure is eventually applied to the buffer with
;; `org-list-write-struct'.  This function repairs (bullets,
;; indentation, checkboxes) the list in the process.  It should be
;; called near the end of any function working on structures.

;; Thus, a function applying to lists should usually follow this
;; template:

;; 1. Verify point is in a list and grab item beginning (with the same
;;    function `org-in-item-p').  If the function requires the cursor
;;    to be at item's bullet, `org-at-item-p' is more selective.  It
;;    is also possible to move point to the closest item with
;;    `org-list-search-backward', or `org-list-search-forward',
;;    applied to the function `org-item-beginning-re'.

;; 2. Get list structure with `org-list-struct'.

;; 3. Compute one, or both, helper functions,
;;    (`org-list-parents-alist', `org-list-prevs-alist') depending on
;;    needed accessors.

;; 4. Proceed with the modifications, using methods and accessors.

;; 5. Verify and apply structure to buffer, using
;;    `org-list-write-struct'.

;; 6. If changes made to the list might have modified check-boxes,
;;    call `org-update-checkbox-count-maybe'.

;; Computing a structure can be a costly operation on huge lists (a
;; few thousand lines long).  Thus, code should follow the rule:
;; "collect once, use many".  As a corollary, it is usually a bad idea
;; to use directly an interactive function inside the code, as those,
;; being independent entities, read the whole list structure another
;; time.

The cursor may be at any item of the list that should be sorted.
Sublists are not sorted.  Checkboxes, if any, are ignored.

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

Comparing entries ignores case by default.  However, with an
optional argument WITH-CASE, the sorting considers case as well.

The command prompts for the sorting type unless it has been given
to the function through the SORTING-TYPE argument, which needs to
be a character, \(?n ?N ?a ?A ?t ?T ?f ?F ?x ?X).  Here is the
detailed meaning of each character:

n   Numerically, by converting the beginning of the item to a number.
a   Alphabetically.  Only the first line of item is checked.
t   By date/time, either the first active time stamp in the entry, if
    any, or by the first inactive one.  In a timer list, sort the timers.
x   By \"checked\" status of a check list.

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.  It will then use
COMPARE-FUNC to compare entries.

;;; Internal Functions

;; Internal functions fall into three categories.

;; The first one is about text formatting.  The core function is
;; `org-ascii--current-text-width', which determines the current
;; text width allowed to a given element.  In other words, it helps
;; keeping each line width within maximum text width defined in
;; `org-ascii-text-width'.  Once this information is known,
;; `org-ascii--fill-string', `org-ascii--justify-string',
;; `org-ascii--box-string' and `org-ascii--indent-string' can
;; operate on a given output string.

;; The second category contains functions handling elements listings,
;; triggered by "#+TOC:" keyword.  As such, `org-ascii--build-toc'
;; returns a complete table of contents, `org-ascii--list-listings'
;; returns a list of referenceable src-block elements, and
;; `org-ascii--list-tables' does the same for table elements.

;; The third category includes general helper functions.
;; `org-ascii--build-title' creates the title for a given headline
;; or inlinetask element.  `org-ascii--build-caption' returns the
;; caption string associated to a table or a src-block.
;; `org-ascii--describe-links' creates notes about links for
;; insertion at the end of a section.  It uses
;; `org-ascii--unique-links' to get the list of links to describe.
;; Eventually, `org-ascii--translate' translates a string according
;; to language and charset specification.

;;
;; Synopsis
;; ========
;;
;; Allows org-mode to make use of the Emacs `etags' system.  Defines tag
;; destinations in org-mode files as any text between <>. This allows the tags-generation program `exuberant ctags' to
;; parse these files and create tag tables that record where these
;; destinations are found.  Plain [[links]] in org mode files which do not have
;; <> within the same file will then be interpreted as
;; links to these 'tagged' destinations, allowing seamless navigation between
;; multiple org-mode files.  Topics can be created in any org mode file and
;; will always be found by plain links from other files.  Other file types
;; recognized by ctags (source code files, latex files, etc) will also be
;; available as destinations for plain links, and similarly, org-mode links
;; will be available as tags from source files.  Finally, the function
;; `org-ctags-find-tag-interactive' lets you choose any known tag, using
;; autocompletion, and quickly jump to it.
;;
;; Installation
;; ============
;;
;; Install org mode
;; Ensure org-ctags.el is somewhere in your emacs load path.
;; Download and install Exuberant ctags -- "http://ctags.sourceforge.net/"
;; Edit your .emacs file (see next section) and load emacs.

;; To put in your init file (.emacs):
;; ==================================
;;
;; Assuming you already have org mode installed and set up:
;;
;;    (setq org-ctags-path-to-ctags "/path/to/ctags/executable")
;;    (add-hook 'org-mode-hook
;;      (lambda ()
;;        (define-key org-mode-map "\C-co" 'org-ctags-find-tag-interactive)))
;;
;; By default, with org-ctags loaded, org will first try and visit the tag
;; with the same name as the link; then, if unsuccessful, ask the user if
;; he/she wants to rebuild the 'TAGS' database and try again; then ask if
;; the user wishes to append 'tag' as a new toplevel heading at the end of
;; the buffer; and finally, defer to org's default behaviour which is to
;; search the entire text of the current buffer for 'tag'.
;;
;; This behaviour can be modified by changing the value of
;; ORG-CTAGS-OPEN-LINK-FUNCTIONS. For example I have the following in my
;; .emacs, which describes the same behaviour as the above paragraph with
;; one difference:
;;
;; (setq org-ctags-open-link-functions
;;       '(org-ctags-find-tag
;;         org-ctags-ask-rebuild-tags-file-then-find-tag
;;         org-ctags-ask-append-topic
;;         org-ctags-fail-silently))  ; <-- prevents org default behaviour
;;
;;
;; Usage
;; =====
;;
;; When you click on a link "[[foo]]" and org cannot find a matching "<>"
;; in the current buffer, the tags facility will take over.  The file TAGS in
;; the active directory is examined to see if the tags facility knows about
;; "<>" in any other files.  If it does, the matching file will be opened
;; and the cursor will jump to the position of "<>" in that file.
;;
;; User-visible functions:
;; - `org-ctags-find-tag-interactive': type a tag (plain link) name and visit
;;   it.  With autocompletion.  Bound to ctrl-O in the above setup.
;; - All the etags functions should work.  These include:
;;
;;      M-.    `find-tag' -- finds the tag at point
;;
;;      C-M-.  find-tag based on regular expression
;;
;;      M-x tags-search RET -- like C-M-. but searches through ENTIRE TEXT
;;             of ALL the files referenced in the TAGS file.  A quick way to
;;             search through an entire 'project'.
;;
;;      M-*    "go back" from a tag jump.  Like `org-mark-ring-goto'.
;;             You may need to bind this key yourself with (eg)
;;             (global-set-key (kbd "") 'pop-tag-mark)
;;
;;      (see etags chapter in Emacs manual for more)
;;
;;
;; Keeping the TAGS file up to date
;; ================================
;;
;; Tags mode has no way of knowing that you have created new tags by typing in
;; your org-mode buffer.  New tags make it into the TAGS file in 3 ways:
;;
;; 1. You re-run (org-ctags-create-tags "directory") to rebuild the file.
;; 2. You put the function `org-ctags-ask-rebuild-tags-file-then-find-tag' in
;;    your `org-open-link-functions' list, as is done in the setup
;;    above.  This will cause the TAGS file to be rebuilt whenever a link
;;    cannot be found.  This may be slow with large file collections however.

;;; Commentary:
;;
;; Org syntax can be divided into three categories: "Greater
;; elements", "Elements" and "Objects".
;;
;; Elements are related to the structure of the document.  Indeed, all
;; elements are a cover for the document: each position within belongs
;; to at least one element.
;;
;; An element always starts and ends at the beginning of a line.  With
;; a few exceptions (`clock', `headline', `inlinetask', `item',
;; `planning', `node-property', `quote-section' `section' and
;; `table-row' types), it can also accept a fixed set of keywords as
;; attributes.  Those are called "affiliated keywords" to distinguish
;; them from other keywords, which are full-fledged elements.  Almost
;; all affiliated keywords are referenced in
;; `org-element-affiliated-keywords'; the others are export attributes
;; and start with "ATTR_" prefix.
;;
;; Element containing other elements (and only elements) are called
;; greater elements.  Concerned types are: `center-block', `drawer',
;; `dynamic-block', `footnote-definition', `headline', `inlinetask',
;; `item', `plain-list', `property-drawer', `quote-block', `section'
;; and `special-block'.
;;
;; Other element types are: `babel-call', `clock', `comment',
;; `comment-block', `diary-sexp', `example-block', `export-block',
;; `fixed-width', `horizontal-rule', `keyword', `latex-environment',
;; `node-property', `paragraph', `planning', `quote-section',
;; `src-block', `table', `table-row' and `verse-block'.  Among them,
;; `paragraph' and `verse-block' types can contain Org objects and
;; plain text.
;;
;; Objects are related to document's contents.  Some of them are
;; recursive.  Associated types are of the following: `bold', `code',
;; `entity', `export-snippet', `footnote-reference',
;; `inline-babel-call', `inline-src-block', `italic',
;; `latex-fragment', `line-break', `link', `macro', `radio-target',
;; `statistics-cookie', `strike-through', `subscript', `superscript',
;; `table-cell', `target', `timestamp', `underline' and `verbatim'.
;;
;; Some elements also have special properties whose value can hold
;; objects themselves (i.e. an item tag or a headline name).  Such
;; values are called "secondary strings".  Any object belongs to
;; either an element or a secondary string.
;;
;; Notwithstanding affiliated keywords, each greater element, element
;; and object has a fixed set of properties attached to it.  Among
;; them, four are shared by all types: `:begin' and `:end', which
;; refer to the beginning and ending buffer positions of the
;; considered element or object, `:post-blank', which holds the number
;; of blank lines, or white spaces, at its end and `:parent' which
;; refers to the element or object containing it.  Greater elements,
;; elements and objects containing objects will also have
;; `:contents-begin' and `:contents-end' properties to delimit
;; contents.  Eventually, greater elements and elements accepting
;; affiliated keywords will have a `:post-affiliated' property,
;; referring to the buffer position after all such keywords.
;;
;; At the lowest level, a `:parent' property is also attached to any
;; string, as a text property.
;;
;; Lisp-wise, an element or an object can be represented as a list.
;; It follows the pattern (TYPE PROPERTIES CONTENTS), where:
;;   TYPE is a symbol describing the Org element or object.
;;   PROPERTIES is the property list attached to it.  See docstring of
;;              appropriate parsing function to get an exhaustive
;;              list.
;;   CONTENTS is a list of elements, objects or raw strings contained
;;            in the current element or object, when applicable.
;;
;; An Org buffer is a nested list of such elements and objects, whose
;; type is `org-data' and properties is nil.
;;
;; The first part of this file defines Org syntax, while the second
;; one provide accessors and setters functions.
;;
;; The next part implements a parser and an interpreter for each
;; element and object type in Org syntax.
;;
;; The following part creates a fully recursive buffer parser.  It
;; also provides a tool to map a function to elements or objects
;; matching some criteria in the parse tree.  Functions of interest
;; are `org-element-parse-buffer', `org-element-map' and, to a lesser
;; extent, `org-element-parse-secondary-string'.
;;
;; The penultimate part is the cradle of an interpreter for the
;; obtained parse tree: `org-element-interpret-data'.
;;
;; The library ends by furnishing `org-element-at-point' function, and
;; a way to give information about document structure around point
;; with `org-element-context'.


;;; Code:

(eval-when-compile (require 'cl))
(require 'org)



;;; Definitions And Rules
;;
;; Define elements, greater elements and specify recursive objects,
;; along with the affiliated keywords recognized.  Also set up
;; restrictions on recursive objects combinations.
;;
;; These variables really act as a control center for the parsing
;; process.

;; argument to toggle parsing of that secondary string.  Moreover,
;; `item' parser requires current list's structure as its first
;; element.
;;
;; An interpreter accepts two arguments: the list representation of
;; the element or object, and its contents.  The latter may be nil,
;; depending on the element or object considered.  It returns the
;; appropriate Org syntax, as a string.
;;
;; Parsing functions must follow the naming convention:
;; org-element-TYPE-parser, where TYPE is greater element's type, as
;; defined in `org-element-greater-elements'.
;;
;; Similarly, interpreting functions must follow the naming
;; convention: org-element-TYPE-interpreter.
;;
;; With the exception of `headline' and `item' types, greater elements
;; cannot contain other greater elements of their own type.
;;
;; Beside implementing a parser and an interpreter, adding a new
;; greater element requires to tweak `org-element--current-element'.
;; Moreover, the newly defined type must be added to both

;; Successors follow the naming convention:
;; org-element-NAME-successor, where NAME is the name of the
;; successor, as defined in `org-element-all-successors'.
;;
;; Some object types (i.e. `italic') are recursive.  Restrictions on
;; object types they can contain will be specified in
;; `org-element-object-restrictions'.
;;
;; Adding a new type of object is simple.  Implement a successor,

;;; The Org Parser
;;

;; region, narrowing, or even visibility if specified, and
;; `org-element-parse-secondary-string', which parses objects within
;; a given string.
;;
;; The (almost) almighty `org-element-map' allows to apply a function
;; on elements or objects matching some type, and accumulate the
;; resulting values.  In an export situation, it also skips unneeded
;; parts of the parse tree.

(defun org-element-parse-buffer (&optional granularity visible-only)
  "Recursively parse the buffer and return structure.
If narrowing is in effect, only parse the visible part of the
buffer.

Optional argument GRANULARITY determines the depth of the
recursion.  It can be set to the following symbols:

`headline'          Only parse headlines.
`greater-element'   Don't recurse into greater elements excepted
		    headlines and sections.  Thus, elements
		    parsed are the top-level ones.
`element'           Parse everything but objects and plain text.
`object'            Parse the complete buffer (default).

When VISIBLE-ONLY is non-nil, don't parse contents of hidden
elements.

An element or an objects is represented as a list with the
pattern (TYPE PROPERTIES CONTENTS), where :

  TYPE is a symbol describing the element or object.  See
  `org-element-all-elements' and `org-element-all-objects' for an
  exhaustive list of such symbols.  One can retrieve it with
  `org-element-type' function.

  PROPERTIES is the list of attributes attached to the element or
  object, as a plist.  Although most of them are specific to the
  element or object type, all types share `:begin', `:end',
  `:post-blank' and `:parent' properties, which respectively
  refer to buffer position where the element or object starts,
  ends, the number of white spaces or blank lines after it, and
  the element or object containing it.  Properties values can be
  obtained by using `org-element-property' function.

  CONTENTS is a list of elements, objects or raw strings
  contained in the current element or object, when applicable.
  One can access them with `org-element-contents' function.

The Org buffer has `org-data' as type and nil as properties.
`org-element-map' function can be used to find specific elements
or objects within the parse tree.

This function assumes that current major mode is `org-mode'."

DATA is a parse tree, an element, an object, a string, or a list
of such constructs.  TYPES is a symbol or list of symbols of
elements or objects types (see `org-element-all-elements' and
`org-element-all-objects' for a complete list of types).  FUN is
the function called on the matching element or object.  It has to
accept one argument: the element or object itself.

When optional argument INFO is non-nil, it should be a plist
holding export options.  In that case, parts of the parse tree
not exportable according to that property list will be skipped.

When optional argument FIRST-MATCH is non-nil, stop at the first
match for which FUN doesn't return nil, and return that value.

Optional argument NO-RECURSION is a symbol or a list of symbols
representing elements or objects types.  `org-element-map' won't
enter any recursive element or object whose type belongs to that
list.  Though, FUN can still be applied on them.

When optional argument WITH-AFFILIATED is non-nil, FUN will also
apply to matching objects within parsed affiliated keywords (see
`org-element-parsed-keywords').

Nil values returned from FUN do not appear in the results.


Examples:
---------

Assuming TREE is a variable containing an Org buffer parse tree,
the following example will return a flat list of all `src-block'
and `example-block' elements in it:

  \(org-element-map tree '(example-block src-block) 'identity)

The following snippet will find the first headline with a level
of 1 and a \"phone\" tag, and will return its beginning position:

  \(org-element-map tree 'headline
   \(lambda (hl)
     \(and (= (org-element-property :level hl) 1)
          \(member \"phone\" (org-element-property :tags hl))
          \(org-element-property :begin hl)))
   nil t)

The next example will return a flat list of all `plain-list' type
elements in TREE that are not a sub-list themselves:

  \(org-element-map tree 'plain-list 'identity nil nil 'plain-list)

Eventually, this example will return a flat list of all `bold'
type objects containing a `latex-snippet' type object, even
looking into captions:

  \(org-element-map tree 'bold
   \(lambda (b)
     \(and (org-element-map b 'latex-snippet 'identity nil t) b))

;;; Commentary:

;; This file contains an alternative implementation of the functionality
;; that used to be provided by org-remember.el.  The implementation is more
;; streamlined, can produce more target types (e.g. plain list items or
;; table lines).  Also, it does not use a temporary buffer for editing
;; the captured entry - instead it uses an indirect buffer that visits
;; the new entry already in the target buffer (this was an idea by Samuel
;; Wales).  John Wiegley's excellent `remember.el' is not needed anymore
;; for this implementation, even though we borrow heavily from its ideas.

;; This implementation heavily draws on ideas by James TD Smith and
;; Samuel Wales, and, of cause, uses John Wiegley's remember.el as inspiration.

;;; TODO

;; - find a clever way to not always insert an annotation maybe a
;;   predicate function that can check for conditions for %a to be
;;   used.  This could be one of the properties.

;; - Should there be plist members that arrange for properties to be
;;   asked for, like James proposed in his RFC?

Each entry is a list with the following items:

keys         The keys that will select the template, as a string, characters
             only, for example \"a\" for a template to be selected with a
             single key, or \"bt\" for selection with two keys.  When using
             several keys, keys using the same prefix key must be together
             in the list and preceded by a 2-element entry explaining the
             prefix key, for example

                     (\"b\" \"Templates for marking stuff to buy\")

             The \"C\" key is used by default for quick access to the
             customization of the template variable.  But if you want to use
             that key for a template, you can.

description  A short string describing the template, will be shown during
             selection.

type         The type of entry.  Valid types are:
               entry       an Org-mode node, with a headline.  Will be
                           filed as the child of the target entry or as
                           a top-level entry.
               item        a plain list item, will be placed in the
                           first plain list at the target
                           location.
               checkitem   a checkbox item.  This differs from the
                           plain list item only is so far as it uses a
                           different default template.
               table-line  a new line in the first table at target location.
               plain       text to be inserted as it is.

target       Specification of where the captured item should be placed.
             In Org-mode files, targets usually define a node.  Entries will
             become children of this node, other types will be added to the
             table or list in the body of this node.

             Most target specifications contain a file name.  If that file
             name is the empty string, it defaults to `org-default-notes-file'.
             A file can also be given as a variable, function, or Emacs Lisp
             form.

             Valid values are:

             (file \"path/to/file\")
                 Text will be placed at the beginning or end of that file

             (id \"id of existing org entry\")
                 File as child of this entry, or in the body of the entry

             (file+headline \"path/to/file\" \"node headline\")
                 Fast configuration if the target heading is unique in the file

             (file+olp \"path/to/file\" \"Level 1 heading\" \"Level 2\" ...)
                 For non-unique headings, the full path is safer

             (file+regexp  \"path/to/file\" \"regexp to find location\")
                 File to the entry matching regexp

             (file+datetree \"path/to/file\")
                 Will create a heading in a date tree for today's date

             (file+datetree+prompt \"path/to/file\")
                 Will create a heading in a date tree, prompts for date

             (file+function \"path/to/file\" function-finding-location)
                 A function to find the right location in the file

             (clock)
                File to the entry that is currently being clocked

             (function function-finding-location)
                Most general way, write your own function to find both
                file and location

template     The template for creating the capture item.  If you leave this
             empty, an appropriate default template will be used.  See below
             for more details.  Instead of a string, this may also be one of

                 (file \"/path/to/template-file\")
                 (function function-returning-the-template)

             in order to get a template from a file, or dynamically
             from a function.

The rest of the entry is a property list of additional options.  Recognized
properties are:

 :prepend            Normally newly captured information will be appended at
                     the target location (last child, last table line,
                     last list item...).  Setting this property will
                     change that.

 :immediate-finish   When set, do not offer to edit the information, just
                     file it away immediately.  This makes sense if the
                     template only needs information that can be added
                     automatically.

 :jump-to-captured   When set, jump to the captured entry when finished.

 :empty-lines        Set this to the number of lines the should be inserted
                     before and after the new item.  Default 0, only common
                     other value is 1.

 :empty-lines-before Set this to the number of lines the should be inserted
                     before the new item.  Overrides :empty-lines for the
                     number lines inserted before.

 :empty-lines-after  Set this to the number of lines the should be inserted
                     after the new item.  Overrides :empty-lines for the
                     number of lines inserted after.

 :clock-in           Start the clock in this item.

 :clock-keep         Keep the clock running when filing the captured entry.

 :clock-resume       Start the interrupted clock when finishing the capture.
                     Note that :clock-keep has precedence over :clock-resume.
                     When setting both to `t', the current clock will run and
                     the previous one will not be resumed.

 :unnarrowed         Do not narrow the target buffer, simply show the
                     full buffer.  Default is to narrow it so that you
                     only see the new stuff.

 :table-line-pos     Specification of the location in the table where the
                     new line should be inserted.  It should be a string like
                     \"II-3\", meaning that the new line should become the
                     third line before the second horizontal separator line.

 :kill-buffer        If the target file was not yet visited by a buffer when
                     capture was invoked, kill the buffer again after capture
                     is finalized.

The template defines the text to be inserted.  Often this is an
org-mode entry (so the first line should start with a star) that
will be filed as a child of the target headline.  It can also be
freely formatted text.  Furthermore, the following %-escapes will
be replaced with content and expanded in this order:

  %[pathname] Insert the contents of the file given by `pathname'.
  %(sexp)     Evaluate elisp `(sexp)' and replace it with the results.
              For convenience, %:keyword (see below) placeholders within
              the expression will be expanded prior to this.
  %<...>      The result of format-time-string on the ... format specification.
  %t          Time stamp, date only.
  %T          Time stamp with date and time.
  %u, %U      Like the above, but inactive time stamps.
  %i          Initial content, copied from the active region.  If %i is
              indented, the entire inserted text will be indented as well.
  %a          Annotation, normally the link created with `org-store-link'.
  %A          Like %a, but prompt for the description part.
  %l          Like %a, but only insert the literal link.
  %c          Current kill ring head.
  %x          Content of the X clipboard.
  %k          Title of currently clocked task.
  %K          Link to currently clocked task.
  %n          User name (taken from the variable `user-full-name').
  %f          File visited by current buffer when org-capture was called.
  %F          Full path of the file or directory visited by current buffer.
  %:keyword   Specific information for certain link types, see below.
  %^g         Prompt for tags, with completion on tags in target file.
  %^G         Prompt for tags, with completion on all tags in all agenda files.
  %^t         Like %t, but prompt for date.  Similarly %^T, %^u, %^U.
              You may define a prompt like: %^{Please specify birthday}t
  %^C         Interactive selection of which kill or clip to use.
  %^L         Like %^C, but insert as link.
  %^{prop}p   Prompt the user for a value for property `prop'.
  %^{prompt}  Prompt the user for a string and replace this sequence with it.
              A default value and a completion table ca be specified like this:
              %^{prompt|default|completion2|completion3|...}.
  %?          After completing the template, position cursor here.
  %\\n         Insert the text entered at the nth %^{prompt}, where `n' is
              a number, starting from 1.

Apart from these general escapes, you can access information specific to
the link type that is created.  For example, calling `org-capture' in emails
or in Gnus will record the author and the subject of the message, which you

   that there are entries following with keys like \"ab\", \"ax\"...

2. Selectable members must have more than two elements, with the first
   being the string of keys that lead to selecting it, and the second a
   short description string of the item.

The command will then make a temporary buffer listing all entries
that can be selected with a single key, and all the single key
prefixes.  When you press the key for a single-letter entry, it is selected.
When you press a prefix key, the commands (and maybe further prefixes)
under this key will be shown and offered for selection.

TITLE will be placed over the selection in the temporary buffer,
PROMPT will be used when prompting for a key.  SPECIAL is an alist with
also (\"key\" \"description\") entries.  When one of these is selection,

;; + Upload HTML, images, attachments and other files to a web server
;; + Exclude selected private pages from publishing
;; + Publish a clickable sitemap of pages

;;; Variables

(defvar org-publish-temp-files nil
  "Temporary list of files to be published.")

;; Here, so you find the variable right before it's used the first time:
(defvar org-publish-cache nil
  "This will cache timestamps and titles for files in publishing projects.
Blocks could hash sha1 values here.")

(defgroup org-publish nil
  "Options for publishing a set of Org-mode and related files."
  :tag "Org Publishing"
  :group 'org)

(defcustom org-publish-project-alist nil
  "Association list to control publishing behavior.
Each element of the alist is a publishing 'project.'  The CAR of
each element is a string, uniquely identifying the project.  The
CDR of each element is in one of the following forms:

1. A well-formed property list with an even number of elements,
   alternating keys and values, specifying parameters for the
   publishing process.

     \(:property value :property value ... )

2. A meta-project definition, specifying of a list of
   sub-projects:

     \(:components (\"project-1\" \"project-2\" ...))

When the CDR of an element of org-publish-project-alist is in
this second form, the elements of the list after `:components'
are taken to be components of the project, which group together
files requiring different publishing options.  When you publish
such a project with \\[org-publish], the components all publish.

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.  However, options set within
a file override everything.

Most properties are optional, but some should always be set:

  `:base-directory'

    Directory containing publishing source files.

  `:base-extension'

    Extension (without the dot!) of source files.  This can be
    a regular expression.  If not given, \"org\" will be used as
    default extension.

  `:publishing-directory'

    Directory (possibly remote) where output files will be
    published.

The `:exclude' property may be used to prevent certain files from
being published.  Its value may be a string or regexp matching
file names you don't want to be published.

The `:include' property may be used to include extra files.  Its
value may be a list of filenames to include.  The filenames are
considered relative to the base directory.

When both `:include' and `:exclude' properties are given values,
the exclusion step happens first.

One special property controls which back-end function to use for
publishing files in the project.  This can be used to extend the
set of file types publishable by `org-publish', as well as the
set of output formats.

  `:publishing-function'

    Function to publish file.  Each back-end may define its
    own (i.e. `org-latex-publish-to-pdf',
    `org-html-publish-to-html').  May be a list of functions, in
    which case each function in the list is invoked in turn.

Another property allows you to insert code that prepares
a project for publishing.  For example, you could call GNU Make
on a certain makefile, to ensure published files are built up to
date.

  `:preparation-function'

    Function to be called before publishing this project.  This
    may also be a list of functions.

  `:completion-function'

    Function to be called after publishing this project.  This
    may also be a list of functions.

Some properties control details of the Org publishing process,
and are equivalent to the corresponding user variables listed in
the right column.  Back-end specific properties may also be
included.  See the back-end documentation for more information.

The following properties may be used to control publishing of
a site-map of files or summary page for a given project.

  `:auto-sitemap'

    Whether to publish a site-map during
    `org-publish-current-project' or `org-publish-all'.

  `:sitemap-filename'

    Filename for output of sitemap.  Defaults to \"sitemap.org\".

  `:sitemap-title'

    Title of site-map page.  Defaults to name of file.

  `:sitemap-function'

    Plugin function to use for generation of site-map.  Defaults
    to `org-publish-org-sitemap', which generates a plain list of
    links to all files in the project.

  `:sitemap-style'

    Can be `list' (site-map is just an itemized list of the
    titles of the files involved) or `tree' (the directory
    structure of the source files is reflected in the site-map).
    Defaults to `tree'.

  `:sitemap-sans-extension'

    Remove extension from site-map's file-names.  Useful to have
    cool URIs (see http://www.w3.org/Provider/Style/URI).
    Defaults to nil.

If you create a site-map file, adjust the sorting like this:

  `:sitemap-sort-folders'

    Where folders should appear in the site-map.  Set this to
    `first' (default) or `last' to display folders first or last,
    respectively.  Any other value will mix files and folders.

  `:sitemap-sort-files'

    The site map is normally sorted alphabetically.  You can
    change this behaviour setting this to `anti-chronologically',
    `chronologically', or nil.

  `:sitemap-ignore-case'

    Should sorting be case-sensitive?  Default nil.

The following property control the creation of a concept index.

  `:makeindex'

    Create a concept index.  The file containing the index has to
    be called \"theindex.org\".  If it doesn't exist in the
    project, it will be generated.  Contents of the index are
    stored in the file \"theindex.inc\", which can be included in
    \"theindex.org\".

;;; Commentary:

;; This file implements links to an IRC session from within Org-mode.
;; Org-mode loads this module by default - if this is not what you want,
;; configure the variable `org-modules'.
;;
;; Please customize the variable `org-modules' to select
;; extensions you would like to use, and to deselect those which you don't
;; want.
;;
;; Please note that at the moment only ERC is supported.  Other clients
;; shouldn't be difficult to add though.
;;
;; Then set `org-irc-link-to-logs' to non-nil if you would like a
;; file:/ type link to be created to the current line in the logs or
;; to t if you would like to create an irc:/ style link.
;;
;; Links within an org buffer might look like this:
;;
;; [[irc:/irc.freenode.net/#emacs/bob][chat with bob in #emacs on freenode]]
;; [[irc:/irc.freenode.net/#emacs][#emacs on freenode]]
;; [[irc:/irc.freenode.net/]]
;;
;; If, when the resulting link is visited, there is no connection to a
;; requested server then one will be created.

                       Version 3, 29 June 2007

 Copyright (C) 2007 Free Software Foundation, Inc. 
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.

                            Preamble

  The GNU General Public License is a free, copyleft license for
software and other kinds of works.

  The licenses for most software and other practical works are designed
to take away your freedom to share and change the works.  By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users.  We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors.  You can apply it to
your programs, too.

  When we speak of free software, we are referring to freedom, not
price.  Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.

  To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights.  Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.

  For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received.  You must make sure that they, too, receive
or can get the source code.  And you must show them these terms so they
know their rights.

  Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.

  For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software.  For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.

  Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so.  This is fundamentally incompatible with the aim of
protecting users' freedom to change the software.  The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable.  Therefore, we
have designed this version of the GPL to prohibit the practice for those
products.  If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.

  Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary.  To prevent this, the GPL assures that
patents cannot be used to render the program non-free.

  The precise terms and conditions for copying, distribution and
modification follow.

                       TERMS AND CONDITIONS

  0. Definitions.

  "This License" refers to version 3 of the GNU General Public License.

  "Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.

  "The Program" refers to any copyrightable work licensed under this
License.  Each licensee is addressed as "you".  "Licensees" and
"recipients" may be individuals or organizations.

  To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy.  The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.

  A "covered work" means either the unmodified Program or a work based
on the Program.

  To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy.  Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.

  To "convey" a work means any kind of propagation that enables other
parties to make or receive copies.  Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.

  An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License.  If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.

  1. Source Code.

  The "source code" for a work means the preferred form of the work
for making modifications to it.  "Object code" means any non-source
form of a work.

  A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.

  The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form.  A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.

  The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities.  However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work.  For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.

  The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.

  The Corresponding Source for a work in source code form is that
same work.

  2. Basic Permissions.

  All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met.  This License explicitly affirms your unlimited
permission to run the unmodified Program.  The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work.  This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.

  You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force.  You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright.  Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.

  Conveying under any other circumstances is permitted solely under
the conditions stated below.  Sublicensing is not allowed; section 10
makes it unnecessary.

  3. Protecting Users' Legal Rights From Anti-Circumvention Law.

  No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.

  When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.

  4. Conveying Verbatim Copies.

  You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.

  You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.

  5. Conveying Modified Source Versions.

  You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:

    a) The work must carry prominent notices stating that you modified
    it, and giving a relevant date.

    b) The work must carry prominent notices stating that it is
    released under this License and any conditions added under section
    7.  This requirement modifies the requirement in section 4 to
    "keep intact all notices".

    c) You must license the entire work, as a whole, under this
    License to anyone who comes into possession of a copy.  This
    License will therefore apply, along with any applicable section 7
    additional terms, to the whole of the work, and all its parts,
    regardless of how they are packaged.  This License gives no
    permission to license the work in any other way, but it does not
    invalidate such permission if you have separately received it.

    d) If the work has interactive user interfaces, each must display
    Appropriate Legal Notices; however, if the Program has interactive
    interfaces that do not display Appropriate Legal Notices, your
    work need not make them do so.

  A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit.  Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.

  6. Conveying Non-Source Forms.

  You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:

    a) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by the
    Corresponding Source fixed on a durable physical medium
    customarily used for software interchange.

    b) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by a
    written offer, valid for at least three years and valid for as
    long as you offer spare parts or customer support for that product
    model, to give anyone who possesses the object code either (1) a
    copy of the Corresponding Source for all the software in the
    product that is covered by this License, on a durable physical
    medium customarily used for software interchange, for a price no
    more than your reasonable cost of physically performing this
    conveying of source, or (2) access to copy the
    Corresponding Source from a network server at no charge.

    c) Convey individual copies of the object code with a copy of the
    written offer to provide the Corresponding Source.  This
    alternative is allowed only occasionally and noncommercially, and
    only if you received the object code with such an offer, in accord
    with subsection 6b.

    d) Convey the object code by offering access from a designated
    place (gratis or for a charge), and offer equivalent access to the
    Corresponding Source in the same way through the same place at no
    further charge.  You need not require recipients to copy the
    Corresponding Source along with the object code.  If the place to
    copy the object code is a network server, the Corresponding Source
    may be on a different server (operated by you or a third party)
    that supports equivalent copying facilities, provided you maintain
    clear directions next to the object code saying where to find the
    Corresponding Source.  Regardless of what server hosts the
    Corresponding Source, you remain obligated to ensure that it is
    available for as long as needed to satisfy these requirements.

    e) Convey the object code using peer-to-peer transmission, provided
    you inform other peers where the object code and Corresponding
    Source of the work are being offered to the general public at no
    charge under subsection 6d.

  A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.

  A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling.  In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage.  For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product.  A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.

  "Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source.  The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.

  If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information.  But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).

  The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed.  Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.

  Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.

  7. Additional Terms.

  "Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law.  If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.

  When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it.  (Additional permissions may be written to require their own
removal in certain cases when you modify the work.)  You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.

  Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:

    a) Disclaiming warranty or limiting liability differently from the
    terms of sections 15 and 16 of this License; or

    b) Requiring preservation of specified reasonable legal notices or
    author attributions in that material or in the Appropriate Legal
    Notices displayed by works containing it; or

    c) Prohibiting misrepresentation of the origin of that material, or
    requiring that modified versions of such material be marked in
    reasonable ways as different from the original version; or

    d) Limiting the use for publicity purposes of names of licensors or
    authors of the material; or

    e) Declining to grant rights under trademark law for use of some
    trade names, trademarks, or service marks; or

    f) Requiring indemnification of licensors and authors of that
    material by anyone who conveys the material (or modified versions of
    it) with contractual assumptions of liability to the recipient, for
    any liability that these contractual assumptions directly impose on
    those licensors and authors.

  All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10.  If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term.  If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.

  If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.

  Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.

  8. Termination.

  You may not propagate or modify a covered work except as expressly
provided under this License.  Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).

  However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.

  Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.

  Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License.  If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.

  9. Acceptance Not Required for Having Copies.

  You are not required to accept this License in order to receive or
run a copy of the Program.  Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance.  However,
nothing other than this License grants you permission to propagate or
modify any covered work.  These actions infringe copyright if you do
not accept this License.  Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.

  10. Automatic Licensing of Downstream Recipients.

  Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License.  You are not responsible
for enforcing compliance by third parties with this License.

  An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations.  If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.

  You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License.  For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.

  11. Patents.

  A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based.  The
work thus licensed is called the contributor's "contributor version".

  A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version.  For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.

  Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.

  In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement).  To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.

  If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients.  "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.

  If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.

  A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License.  You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.

  Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.

  12. No Surrender of Others' Freedom.

  If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License.  If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all.  For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.

  13. Use with the GNU Affero General Public License.

  Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work.  The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.

  14. Revised Versions of this License.

  The Free Software Foundation may publish revised and/or new versions of
the GNU General Public License from time to time.  Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.

  Each version is given a distinguishing version number.  If the
Program specifies that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation.  If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.

  If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.

  Later license versions may give you additional or different
permissions.  However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.

  15. Disclaimer of Warranty.

  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

  16. Limitation of Liability.

  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.

  17. Interpretation of Sections 15 and 16.

  If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.

                     END OF TERMS AND CONDITIONS

            How to Apply These Terms to Your New Programs

  If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.

  To do so, attach the following notices to the program.  It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.

    
    Copyright (C)   

    This program is free software: you can redistribute it and/or modify
    it under the terms of the GNU General Public License as published by
    the Free Software Foundation, either version 3 of the License, or
    (at your option) any later version.

    This program is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
    GNU General Public License for more details.

    You should have received a copy of the GNU General Public License
    along with this program.  If not, see .

Also add information on how to contact you by electronic and paper mail.

  If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:

      Copyright (C)   
    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    This is free software, and you are welcome to redistribute it
    under certain conditions; type `show c' for details.

The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License.  Of course, your program's commands
might be different; for a GUI interface, you would use an "about box".

  You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU GPL, see
.

  The GNU General Public License does not permit incorporating your program
into proprietary programs.  If your program is a subroutine library, you
may consider it more useful to permit linking proprietary applications with
the library.  If this is what you want to do, use the GNU Lesser General
Public License instead of this License.  But first, please read
.
