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

+and diary. Plain text URL-like links connect to websites, emails,
+Usenet messages, BBDB entries, and any files related to the projects.
+For printing and sharing of notes, an Org-mode file can be exported as a
structured ASCII file, as HTML, or (todo and agenda items only) as an
iCalendar file. It can also serve as a publishing tool for a set of
linked webpages.
+An important design aspect that distinguishes Org-mode from for example
+Planner/Muse is that it encourages to store every piece of information
+only once. In Planner, you have project pages, day pages and possibly
+other files, duplicating some information such as tasks. In Org-mode,
+you only have notes files. In your notes you mark entries as tasks,
+label them with tags and timestamps. All necessary lists like a
+schedule for the day, the agenda for a meeting, tasks lists selected by
+tags etc are created dynamically when you need them.
+
Org-mode keeps simple things simple. When first fired up, it should
feel like a straightforward, easy to use outliner. Complexity is not
imposed, but a large amount of functionality is available when you need
it. Org-mode can be used on different levels and in different ways, for
-example:

+
+If you have downloaded Org-mode from the Web, you must take the
+following steps to install it: Go into the Org-mode distribution
+directory and edit the top section of the file @file{Makefile}. You
+must set the name of the Emacs binary (likely either @file{emacs} or
+@file{xemacs}), and the paths to the directories where local Lisp and
+Info files are kept. If you don't have access to the system-wide
+directories, create your own two directories for these files, enter them
+into the Makefile, and make sure Emacs finds the Lisp files by adding
+the following line to @file{.emacs}:
+
+@example
+(setq load-path (cons "~/path/to/lispdir" load-path))
+@end example
+
+@b{XEmacs users now need to install the file @file{noutline.el} from

+@subsubheading How to create a useful backtrace
+
+@cindex backtrace of an error
+If working with Org-mode produces an error with a message you don't
+understand, you may have hit a bug. The best way to report this is by
+providing, in addition to what was mentioned above, a @emph{Backtrace}.
+This is information from the built-in debugger about where and how the
+error occurred. Here is how to produce a useful backtrace:
+
+@enumerate
+@item
+Start a fresh Emacs or XEmacs, and make sure that it will load the
+original Lisp code in @file{org.el} instead of the compiled version in
+@file{org.elc}. The backtrace contains much more information if it is
+produced with uncompiled code. To do this, either rename @file{org.elc}
+to something else before starting Emacs, or ask Emacs explicitly to load
+@file{org.el} by using the command line
+@example
+emacs -l /path/to/org.el
+@end example
+@item
+Go to the @code{Options} menu and select @code{Enter Debugger on Error}
+(XEmacs has this option in the @code{Troubleshooting} sub-menu).
+@item
+Do whatever you have to do to hit the error. Don't forget to
+document the steps you take.
+@item
+When you hit the error, a @file{*Backtrace*} buffer will appear on the
+screen. Save this buffer to a file (for example using @kbd{C-x C-w}) and
+attach it to your bug report.

sparse tree means that the entire document is folded as much as
possible, but the selected information is made visible along with the

Org-mode contains several commands creating such trees. The most
basic one is @command{org-occur}:

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

-The range vectors can be directly fed into the calc vector functions
-like @samp{vmean} and @samp{vsum}.
+Column references can be absolute like @samp{1}, @samp{2},...@samp{N},
+or relative to the current column like @samp{+1} or @samp{-2}.
+
+The row specification only counts data lines and ignores horizontal
+separator lines (hlines). You can use absolute row numbers
+@samp{1}...@samp{N}, and row numbers relative to the current row like
+@samp{+3} or @samp{-1}. Or specify the row relative to one of the
+hlines: @samp{I} refers to the first hline, @samp{II} to the second etc.
+@samp{-I} refers to the first such line above the current line,
+@samp{+I} to the first such line below the current line. You can also
+write @samp{III+2} which is the second data line after the third hline
+in the table. Relative row numbers like @samp{-3} will not cross hlines
+if the current line is too close to the hline. Instead, the value
+directly at the hline is used.
+
+@samp{0} refers to the current row and column. Also, if you omit
+either the column or the row part of the reference, the current
+row/column is implied.
+
+Org-mode's references with @emph{positive} numbers correspond to fixed
+references in other spreadsheet programs. For example, @code{@@3$28}
+corresponds to @code{$AB$3}. Org-mode's references with @emph{negative}
+numbers behave similar to non-fixed references in other spreadsheet
+programs, because when the same formula is used in several fields,
+different fields are referenced each time.
+
+Here are a few examples:
+
+@example
+@@2$3 @r{2nd row, 3rd column}
+$5 @r{column 5 in the current row}
+@@2 @r{current column, row 2}
+@@-1$-3 @r{the field one row up, three columns to the left}

+@end example
+
+@subsubheading Range references
+@cindex range references
+@cindex references, to ranges
+
+You may reference a rectangular range of fields by specifying two field
+references connected by two dots @samp{..}. If both fields are in the
+current row, you may simply use @samp{$2..$7}, but if at least one field
+is in a different row, you need to use the general @code{@@row$column}
+format at least for the first field (i.e the reference must start with
+@samp{@@} in order to be interpreted correctly). Examples:
+
+@example
+$1..$3 @r{First three fields in the current row.}
+$P..$Q @r{Range, using column names (see under Advanced)}
+@@2$1..@@4$3 @r{6 fields between these two fields.}
+@@-1$-2..@@-1 @r{3 numbers from the column to the left, 2 up to current row}
+@end example
+@noindent Range references return a vector of values that can be fed
+into Calc vector functions. Empty fields in ranges are normally
+suppressed, so that the vector contains only the non-empty fields (but
+see the @samp{E} mode switch below). If there are no non-empty fields,

+
+Every item in a plain list (@pxref{Plain lists}) can be made a checkbox
+by starting it with the string @samp{[ ]}. This feature is similar to
+TODO items (@pxref{TODO items}), but more lightweight. Checkboxes are
+not included into the global TODO list, so they are often great to split
+a task into a number of simple steps. Or you can use them in a shopping
+list. To toggle a checkbox, use @kbd{C-c C-c}, or try Piotr Zielinski's
+@file{org-mouse.el}. Here is an example of a checkbox list.
+
+@example
+* TODO Organize party [3/6]
+ - call people [1/3]
+ - [ ] Peter
+ - [X] Sarah
+ - [ ] Sam
+ - [X] order food
+ - [ ] think about what music to play
+ - [X] talk to the neighbors
+@end example
+
+@cindex statistics, for checkboxes
+@cindex checkbox statistics
+The @samp{[3/6]} and @samp{[1/3]} in the first and second line are
+cookies indicating how many checkboxes are present in this entry, and
+how many of them have been checked off. This can give you an idea on
+how many checkboxes remain, even without opening a folded entry. The
+cookies can be placed into a headline or into (the first line of) a
+plain list item. Each cookie covers all checkboxes structurally below
+that headline/item. You have to insert the cookie yourself by typing
+either @samp{[/]} or @samp{[%]}. In the first case you get an @samp{n
+out of m} result, in the second case you get information about the
+percentage of checkboxes checked (in the above example, this would be
+@samp{[50%]} and @samp{[33%], respectively}).
+
+@noindent The following commands work with checkboxes:
+
+@table @kbd
+@kindex C-c C-c
+@item C-c C-c
+Toggle checkbox at point.
+@kindex C-c C-x C-b
+@item C-c C-x C-b
+Toggle checkbox at point.
+@itemize @minus
+@item
+If there is an active region, toggle the first checkbox in the region
+and set all remaining boxes to the same status as the first. If you
+want to toggle all boxes in the region independently, use a prefix
+argument.
+@item
+If the cursor is in a headline, toggle checkboxes in the region between
+this headline and the next (so @emph{not} the entire subtree).
+@item
+If there is no active region, just toggle the checkbox at point.
+@end itemize
+@kindex M-S-@key{RET}
+@item M-S-@key{RET}
+Insert a new item with a checkbox.
+This works only if the cursor is already in a plain list item
+(@pxref{Plain lists}).
+@kindex C-c #
+@item C-c #
+Update the checkbox statistics in the current outline entry. When
+called with a @kbd{C-u} prefix, update the entire file. Checkbox
+statistic cookies are updated automatically if you toggle checkboxes
+with @kbd{C-c C-c} and make new ones with @kbd{M-S-@key{RET}}. If you
+delete boxes or add/change them by hand, use this command to get things
+back into synch. Or simply toggle any checkbox twice with @kbd{C-c C-c}.

+
+Org-mode integrates with the Emacs calendar and diary to display cyclic
+appointments, anniversaries and other special entries in the agenda
+(@pxref{Weekly/Daily agenda}). However, it can be useful to have
+certain deadlines and scheduling items to auto-repeat. The advantage of
+a deadline or scheduled item is that the they produce warnings ahead of
+time and automatically forward themselves in the agenda until they are
+done. The abstract difference is therefore between cyclic
+@i{appointments} and cyclic @i{action items}. For appointments you
+should use the diary, for actions you can uses an org-mode deadline or
+scheduling time stamp together with a REPEAT cookie. For example:
+
+@example
+* TODO Replace batteries in smoke detector REPEAT(+18m)
+ SCHEDULED: <2007-01-01 Mon>
+
+* TODO Get dentist appointment REPEAT(+6m)
+ SCHEDULED: <2006-12-19 Tue>
+
+* TODO Tax report to IRS REPEAT(+1y)
+ DEADLINE: <2007-04-01 Sun>
+@end example
+
+Each time you try to mark one of these entries DONE using @kbd{C-c C-t},
+they will automatically switch back to the state TODO, and the
+deadline/scheduling will be shifted accordingly. The time units
+recognized by org-mode are year (y), month (m), week (w), and day (d).
+Org-mode will also prompt you for a note and record the fact that you
+have closed this item in a note under the headline.
+
+One unusual property of these repeating items is that only one instance
+of each exist at any given time. So if you look back or ahead in the
+agenda, you will not find past and future instances, only the current
+one will show up. Use a cyclic diary entry if you need all past and
+future instances to be visible in the agenda.

positive selection. The AND operator @samp{&} is optional when @samp{+}
-or @samp{-} is present. For example, @samp{+WORK-BOSS} would select all
-headlines that are tagged @samp{:WORK:}, but discard those also tagged
-@samp{:BOSS:}. The search string @samp{WORK|LAPTOP} selects all lines
-tagged @samp{:WORK:} or @samp{:LAPTOP:}. The string
-@samp{WORK|LAPTOP&NIGHT} requires that the @samp{:LAPTOP:} lines are
-also tagged @samp{NIGHT}.

+
+@table @samp
+@item +WORK-BOSS
+Select headlines tagged @samp{:WORK:}, but discard those also tagged
+@samp{:BOSS:}.
+@item WORK|LAPTOP
+Selects lines tagged @samp{:WORK:} or @samp{:LAPTOP:}.
+@item WORK|LAPTOP&NIGHT

+@samp{NIGHT}.
+@end table
+
+@cindex TODO keyword matching, with tags search
+If you are using multi-state TODO keywords (@pxref{TODO extensions}), it
+can be useful to also match on the TODO keyword. This can be done by
+adding a condition after a slash to a tags match. The syntax is similar
+to the tag matches, but should be applied with consideration: For
+example, a positive selection on several TODO keywords can not
+meaningfully be combined with boolean AND. However, @emph{negative
+selection} combined with AND can be meaningful. To make sure that only
+lines are checked that actually have any TODO keyword, use @kbd{C-c a
+M}, or equivalently start the todo part after the slash with @samp{!}.
+Examples:
+
+@table @samp
+@item WORK/WAITING
+Select @samp{:WORK:}-tagged TODO lines with the specific TODO
+keyword @samp{WAITING}.
+@item WORK/!-WAITING-NEXT
+Select @samp{:WORK:}-tagged TODO lines that are neither @samp{WAITING}
+nor @samp{NEXT}
+@item WORK/+WAITING|+NEXT
+Select @samp{:WORK:}-tagged TODO lines that are either @samp{WAITING} or
+@samp{NEXT}.
+@end table
+
+@cindex regular expressions, with tags search
+Any element of the tag/todo match can be a regular expression - in this
+case it must be enclosed in curly braces. For example,
+@samp{WORK+@{^BOSS.*@}} matches headlines that contain the tag
+@samp{WORK} and any tag @i{starting} with @samp{BOSS}.
+
+@cindex level, require for tags match
+You can also require a headline to be of a certain level, by writing
+instead of any TAG an expression like @samp{LEVEL=3}. For example, a
+search @samp{+LEVEL=3+BOSS/-DONE} lists all level three headlines that
+have the tag BOSS and are @emph{not} marked with the todo keyword DONE.

+
+If you are following a system like David Allen's GTD to organize your

+that all projects move along. A @emph{stuck} project is a project that
+has no defined next actions, so it will never show up in the TODO lists
+Org-mode produces. During the review, you need to identify such
+projects and define next actions for them.

+project is and how to find it.
+@end table
+
+You almost certainly will have to configure this view before it will
+work for you. The built-in default assumes that all your projects are
+level-2 headlines, and that a project is not stuck if it has at least
+one entry marked with a todo keyword TODO or NEXT or NEXTACTION.
+
+Lets assume that you, in your own way of using Org-mode, identify
+projects with a tag PROJECT, and that you use a todo keyword MAYBE to
+indicate a project that should not be considered yet. Lets further
+assume that the todo keyword DONE marks finished projects, and that NEXT
+and TODO indicate next actions. Finally, the tag @@SHOP indicates
+shopping and is a next action even without the NEXT tag. In this case
+you would start by identifying eligible projects with a tags/todo match
+@samp{+PROJECT/-MAYBE-DONE}, and then check for TODO, NEXT and @@SHOP in
+the subtree to identify projects that are not stuck. The correct
+customization for this is

+Custom agenda commands serve two purposes: to store and quickly access

+@node Storing searches, Block agenda, Custom agenda views, Custom agenda views
+@subsection Storing searches
+
+The first application of custom searches is the definition of keyboard
+shortcuts for frequently used searches, either creating an agenda
+buffer, or a sparse tree (the latter covering of course only the current
+buffer).
+@kindex C-c a C
+Custom commands are configured in the variable
+@code{org-agenda-custom-commands}. You can customize this variable, for
+example by pressing @kbd{C-c a C}. You can also directly set it with
+Emacs Lisp in @file{.emacs}. The following example contains all valid
+search types:
+
+@lisp
+@group
+(setq org-agenda-custom-commands
+ '(("w" todo "WAITING")
+ ("W" todo-tree "WAITING")
+ ("u" tags "+BOSS-URGENT")
+ ("v" tags-todo "+BOSS-URGENT")
+ ("U" tags-tree "+BOSS-URGENT")
+ ("f" occur-tree "\\<FIXME\\>")))
+@end group
+@end lisp
+
+@noindent
+The initial single-character string in each entry defines the character
+you have to press after the dispatcher command @kbd{C-c a} in order to
+access the command. The second parameter is the search type, followed
+by the string or regular expression to be used for the matching. The
+example above will therefore define:
+
+@table @kbd
+@item C-c a w
+as a global search for TODO entries with @samp{WAITING} as the TODO
+keyword
+@item C-c a W
+as the same search, but only in the current buffer and displaying the
+results as a sparse tree
+@item C-c a u
+as a global tags search for headlines marked @samp{:BOSS:} but not
+@samp{:URGENT:}
+@item C-c a v
+as the same search as @kbd{C-c a u}, but limiting the search to
+headlines that are also TODO items
+@item C-c a U
+as the same search as @kbd{C-c a u}, but only in the current buffer and
+displaying the result as a sparse tree
+@item C-c a f
+to create a sparse tree (again: current buffer only) with all entries
+containing the word @samp{FIXME}.
+@end table
+
+@node Block agenda, Setting Options, Storing searches, Custom agenda views
+@subsection Block agenda
+@cindex block agenda
+@cindex agenda, with block views
+
+Another possibility is the construction of agenda views that comprise
+the results of @emph{several} commands, each of which creates a block in
+the agenda buffer. The available commands include @code{agenda} for the
+daily or weekly agenda (as created with @kbd{C-c a a}), @code{alltodo}
+for the global todo list (as constructed with @kbd{C-c a t}), and the
+matching commands discussed above: @code{todo}, @code{tags}, and
+@code{tags-todo}. Here are two examples:
+
+@lisp
+@group
+(setq org-agenda-custom-commands
+ '(("h" "Agenda and Home-related tasks"
+ ((agenda)
+ (tags-todo "HOME")
+ (tags "GARDEN")))
+ ("o" "Agenda and Office-related tasks"
+ ((agenda)
+ (tags-todo "WORK")
+ (tags "OFFICE")))))
+@end group
+@end lisp
+
+@noindent
+This will define @kbd{C-c a h} to create a multi-block view for stuff
+you need to attend to at home. The resulting agenda buffer will contain
+your agenda for the current week, all TODO items that carry the tag
+@samp{HOME}, and also all lines tagged with @samp{GARDEN}. Finally the
+command @kbd{C-c a o} provides a similar view for office tasks.
+
+
+@node Setting Options, Batch processing, Block agenda, Custom agenda views
+@subsection Setting Options for custom commands
+@cindex options, for custom agenda views
+
+Org-mode contains a number of variables regulating agenda construction
+and display. The global variables define the behavior for all agenda
+commands, including the custom commands. However, if you want to change
+some settings just for a single custom view, you can do so. Setting
+options requires inserting a list of variable names and values at the
+right spot in @code{org-agenda-custom-commands}. For example:
+
+@lisp
+@group
+(setq org-agenda-custom-commands
+ '(("w" todo "WAITING"
+ ((org-agenda-sorting-strategy '(priority-down))
+ (org-agenda-prefix-format " Mixed: ")))
+ ("U" tags-tree "+BOSS-URGENT"
+ ((org-show-following-heading nil)
+ (org-show-hierarchy-above nil)))))
+@end group
+@end lisp
+
+@noindent
+Now the @kbd{C-c a w} command will sort the collected entries only by
+priority, and the prefix format is modified to just say @samp{ Mixed:}
+instead of giving the category of the entry. The sparse tags tree of
+@kbd{C-c a U} will now turn out ultra-compact, because neither the
+headline hierarchy above the match, nor the headline following the match
+will be shown.
+
+For command sets creating a block agenda,
+@code{org-agenda-custom-commands} has two separate spots for setting
+options. You can add options that should be valid for just a single
+command in the set, and options that should be valid for all commands in
+the set. The former are just added to the command entry, the latter
+must come after the list of command entries. Going back to the block
+agenda example (@pxref{Block agenda}), let's change the sorting strategy
+for the @kbd{C-c a h} commands to @code{priority-down}, but let's sort
+the results for GARDEN tags query in the opposite order,
+@code{priority-up}. This would look like this:
+
+@lisp
+@group
+(setq org-agenda-custom-commands
+ '(("h" "Agenda and Home-related tasks"
+ ((agenda)
+ (tags-todo "HOME")
+ (tags "GARDEN" ((org-agenda-sorting-strategy '(priority-up)))))
+ ((org-agenda-sorting-strategy '(priority-down))))
+ ("o" "Agenda and Office-related tasks"
+ ((agenda)
+ (tags-todo "WORK")
+ (tags "OFFICE")))))
+@end group
+@end lisp
+
+As you see, the values and parenthesis setting is a little complex.
+When in doubt, use the customize interface to set this variable - it
+fully supports its structure. Just one caveat: When setting options in
+this interface, the @emph{values} are just lisp expressions. So if the
+value is a string, you need to add the double quotes around the value
+yourself.
+
+@node Batch processing, , Setting Options, Custom agenda views
+@subsection Creating agenda views in batch processing
+@cindex agenda, batch production
+
+If you want to print or otherwise reprocess agenda views, it can be
+useful to create an agenda from the command line. This is the purpose
+of the function @code{org-batch-agenda}. It takes as a parameter one of
+the strings that are the keys in @code{org-agenda-custom-commands}. For
+example, to directly print the current TODO list, you could use
+
+@example
+emacs -batch -l ~/.emacs -eval '(org-batch-agenda "t")' | lpr
+@end example
+
+@noindent
+You may also modify parameters on the fly like this:
+
+@example
+emacs -batch -l ~/.emacs \
+ -eval '(org-batch-agenda "a" \
+ org-agenda-ndays 300 \
+ org-agenda-include-diary nil \
+ org-agenda-files (quote ("~/org/project.org")))' \
+ | lpr
+@end example
+
+@noindent
+which will produce a 300 day agenda, fully restricted to the Org file
+@file{~/org/projects.org}, not even including the diary.

+@section Tables in arbitrary syntax
+@cindex tables, in other modes
+@cindex orgtbl-mode
+
+Since Orgtbl-mode can be used as a minor mode in arbitrary buffers, a
+frequent feature request has been to make it work with native tables in
+specific languages, for example LaTeX. However, this is extremely hard
+to do in a general way, would lead to a customization nightmare, and
+would take away much of the simplicity of the Orgtbl-mode table editor.
+
+This appendix describes a different approach. We keep the Orgtbl-mode
+table in its native format (the @i{source table}), and use a custom
+function to @i{translate} the table to the correct syntax, and to
+@i{install} it in the right location (the @i{target table}). This puts
+the burden of writing conversion functions on the user, but it allows
+for a very flexible system.

+@subsection Radio tables
+@cindex radio tables
+
+To define the location of the target table, you first need to create two
+lines that are comments in the current mode, but contain magic words for
+Orgtbl-mode to find. Orgtbl-mode will insert the translated table
+between these lines, replacing whatever was there before. For example:
+
+@example
+/* BEGIN RECEIVE ORGTBL table_name */
+/* END RECEIVE ORGTBL table_name */
+@end example
+
+@noindent
+Just above the source table, we put a special line that tells
+Orgtbl-mode how to translate this table and where to install it. For
+example:
+@example
+#+ORGTBL: SEND table_name translation_function arguments....
+@end example
+
+@noindent
+@code{table_name} is the reference name for the table that is also used
+in the receiver lines. @code{translation_function} is the Lisp function
+that does the translation. Furthermore, the line can contain a list of
+arguments (alternating key and value) at the end. The arguments will be
+passed as a property list to the translation function for
+interpretation. A few standard parameters are already recognized and
+acted upon before the translation function is called:
+
+@table @code
+@item :skip N
+Skip the first N lines of the table. Hlines do count!
+@item :skipcols (n1 n2 ...)
+List of columns that should be skipped. If the table has a column with
+calculation marks, that column is automatically discarded as well.
+Please note that the translator function sees the table @emph{after} the
+removal of these columns, the function never knows that there have been
+additional columns.
@end table
-@node Dynamic blocks, , Extensions, Extensions and Hacking
+@noindent
+The one problem remaining is how to keep the source table in the buffer
+without disturbing the normal workings of the file, for example during
+compilation of a C file or processing of a LaTeX file. There are a
+number of different solutions:
+
+@itemize @bullet
+@item
+The table could be placed in a block comment if that is supported by the
+language. For example, in C-mode you could wrap the table between
+@samp{/*} and @samp{*/} lines.
+@item
+Sometimes it is possible to put the table after some kind of @i{END}
+statement, for example @samp{\bye} in TeX and @samp{\end@{document@}}
+in LaTeX.
+@item
+You can just comment the table line by line whenever you want to process
+the file, and uncomment it whenever you need to edit the table. This
+only sounds tedious - the command @kbd{M-x orgtbl-toggle-comment} does
+make this comment-toggling very easy, in particular if you bind it to a
+key.
+@end itemize
+
+@node A LaTeX example, Translator functions, Radio tables, Tables in arbitrary syntax
+@subsection A LaTeX example
+@cindex LaTeX, and orgtbl-mode
+
+The best way to wrap the source table in LaTeX is to use the
+@code{comment} environment provided by @file{comment.sty}. It has to be
+activated by placing @code{\usepackage@{comment@}} into the document
+header. Orgtbl-mode can insert a radio table skeleton@footnote{By
+default this works only for LaTeX, HTML, and TeXInfo. Configure the
+variable @code{orgtbl-radio-tables} to install templates for other
+modes.} with the command @kbd{M-x orgtbl-insert-radio-table}. You will
+be prompted for a table name, lets say we use @samp{salesfigures}. You
+will then get the following template:
+
+@example
+% BEGIN RECEIVE ORGTBL salesfigures
+% END RECEIVE ORGTBL salesfigures
+\begin@{comment@}
+#+ORGTBL: SEND salesfigures orgtbl-to-latex
+| | |
+\end@{comment@}
+@end example
+
+@noindent
+The @code{#+ORGTBL: SEND} line tells orgtbl-mode to use the function
+@code{orgtbl-to-latex} to convert the table into LaTeX and to put it
+into the receiver location with name @code{salesfigures}. You may now
+fill in the table, feel free to use the spreadsheet features@footnote{If
+the @samp{#+TBLFM} line contains an odd number of dollar characters,
+this may cause problems with font-lock in latex-mode. As shown in the
+example you can fix this by adding an extra line inside the
+@code{comment} environment that is used to balance the dollar
+expressions. If you are using AUCTeX with the font-latex library, a
+much better solution is to add the @code{comment} environment to the
+variable @code{LaTeX-verbatim-environments}.}:
+
+@example
+% BEGIN RECEIVE ORGTBL salesfigures
+% END RECEIVE ORGTBL salesfigures
+\begin@{comment@}
+#+ORGTBL: SEND salesfigures orgtbl-to-latex
+| Month | Days | Nr sold | per day |
+|-------+------+---------+---------|
+| Jan | 23 | 55 | 2.4 |
+| Feb | 21 | 16 | 0.8 |
+| March | 22 | 278 | 12.6 |
+#+TBLFM: $4=$3/$2;%.1f
+% $ (optional extra dollar to keep font-lock happy, see footnote)
+\end@{comment@}
+@end example
+
+@noindent
+When you are done, press @kbd{C-c C-c} in the table to get the converted
+table inserted between the two marker lines.
+
+Now lets assume you want to make the table header by hand, because you
+want to control how columns are aligned etc. In this case we make sure
+that the table translator does skip the first 2 lines of the source
+table, and tell the command to work as a @i{splice}, i.e. to not produce
+header and footer commands of the target table:
+
+@example
+\begin@{tabular@}@{lrrr@}
+Month & \multicolumn@{1@}@{c@}@{Days@} & Nr.\ sold & per day\\
+% BEGIN RECEIVE ORGTBL salesfigures
+% END RECEIVE ORGTBL salesfigures
+\end@{tabular@}
+%
+\begin@{comment@}
+#+ORGTBL: SEND salesfigures orgtbl-to-latex :splice t :skip 2
+| Month | Days | Nr sold | per day |
+|-------+------+---------+---------|
+| Jan | 23 | 55 | 2.4 |
+| Feb | 21 | 16 | 0.8 |
+| March | 22 | 278 | 12.6 |
+#+TBLFM: $4=$3/$2;%.1f
+\end@{comment@}
+@end example
+
+The LaTeX translator function @code{orgtbl-to-latex} is already part of
+Orgtbl-mode. It uses a @code{tabular} environment to typeset the table
+and marks horizontal lines with @code{\hline}. Furthermore, it
+interprets the following parameters:
+
+@table @code
+@item :splice nil/t
+When set to t, return only table body lines, don't wrap them into a
+tabular environment. Default is nil.
+
+@item :fmt fmt
+A format to be used to wrap each field, should contain @code{%s} for the
+original field value. For example, to wrap each field value in dollars,
+you could use @code{:fmt "$%s$"}. This may also be a property list with
+column numbers and formats. for example @code{:fmt (2 "$%s$" 4 "%s\\%%")}.
+
+@item :efmt efmt
+Use this format to print numbers with exponentials. The format should
+have @code{%s} twice for inserting mantissa and exponent, for example
+@code{"%s\\times10^@{%s@}"}. The default is @code{"%s\\,(%s)"}. This
+may also be a property list with column numbers and formats, for example
+@code{:efmt (2 "$%s\\times10^@{%s@}$" 4 "$%s\\cdot10^@{%s@}$")}. After
+@code{efmt} has been applied to a value, @code{fmt} will also be
+applied.
+@end table
+
+@node Translator functions, , A LaTeX example, Tables in arbitrary syntax
+@subsection Translator functions
+@cindex HTML, and orgtbl-mode
+@cindex translator function
+
+Orgtbl-mode has several translator functions built-in:
+@code{orgtbl-to-latex}, @code{orgtbl-to-html}, and
+@code{orgtbl-to-texinfo}. Except for @code{orgtbl-to-html}@footnote{The
+HTML translator uses the same code that produces tables during HTML
+export.}, these all use a generic translator, @code{orgtbl-to-generic}.
+For example, @code{orgtbl-to-latex} itself is a very short function that
+computes the column definitions for the @code{tabular} environment,
+defines a few field and line separators and then hands over to the
+generic translator. Here is the entire code:
+
+@lisp
+@group
+(defun orgtbl-to-latex (table params)
+ "Convert the orgtbl-mode TABLE to LaTeX."
+ (let* ((alignment (mapconcat (lambda (x) (if x "r" "l"))
+ org-table-last-alignment ""))
+ (params2
+ (list
+ :tstart (concat "\\begin@{tabular@}@{" alignment "@}")
+ :tend "\\end@{tabular@}"
+ :lstart "" :lend " \\\\" :sep " & "
+ :efmt "%s\\,(%s)" :hline "\\hline")))
+ (orgtbl-to-generic table (org-combine-plists params2 params))))
+@end group
+@end lisp
+
+As you can see, the properties passed into the function (variable
+@var{PARAMS}) are combined with the ones newly defined in the function
+(variable @var{PARAMS2}). The ones passed into the function (i.e. the
+ones set by the @samp{ORGTBL SEND} line) take precedence. So if you
+would like to use the LaTeX translator, but wanted the line endings to
+be @samp{\\[2mm]} instead of the default @samp{\\}, you could just
+overrule the default with
+
+@example
+#+ORGTBL: SEND test orgtbl-to-latex :lend " \\\\[2mm]"
+@end example
+
+For a new language, you can either write your own converter function in
+analogy with the LaTeX translator, or you can use the generic function
+directly. For example, if you have a language where a table is started
+with @samp{!BTBL!}, ended with @samp{!ETBL!}, and where table lines are
+started with @samp{!BL!}, ended with @samp{!EL!} and where the field
+separator is a TAB, you could call the generic translator like this (on
+a single line!):
+
+@example
+#+ORGTBL: SEND test orgtbl-to-generic :tstart "!BTBL!" :tend "!ETBL!"
+ :lstart "!BL! " :lend " !EL!" :sep "\t"
+@end example
+
+@noindent
+Please check the documentation string of the function
+@code{orgtbl-to-generic} for a full list of parameters understood by
+that function and remember that you can pass each of them into
+@code{orgtbl-to-latex}, @code{orgtbl-to-texinfo}, and any other function
+using the generic function.
+
+Of course you can also write a completely new function doing complicated
+things the generic translator cannot do. A translator function takes
+two arguments. The first argument is the table, a list of lines, each
+line either the symbol @code{hline} or a list of fields. The second
+argument is the property list containing all parameters specified in the
+@samp{#+ORGTBL: SEND} line. The function must return a single string
+containing the formatted table. If you write a generally useful
+translator, please post it on @code{emacs-orgmode@@gnu.org} so that
+others can benefit from your work.

+of the agenda view, and if not, how much should be skipped.
+
+Let's say you want to produce a list of projects that contain a WAITING
+tag anywhere in the project tree. Let's further assume that you have
+marked all tree headings that define a project with the todo keyword
+PROJECT. In this case you would run a todo search for the keyword
+PROJECT, but skip the match unless there is a WAITING tag anywhere in
+the subtree belonging to the project line.
+
+To achieve this, you must write a function that searches the subtree for
+the tag. If the tag is found, the function must return @code{nil} to
+indicate that this match should not be skipped. If there is no such
+tag, return the location of the end of the subtree, to indicate that
+search should continue from there.
+
+@lisp
+(defun my-skip-unless-waiting ()
+ "Skip trees that are not waiting"
+ (let ((subtree-end (save-excursion (org-end-of-subtree t))))
+ (if (re-search-forward ":WAITING:" subtree-end t)
+ nil ; tag found, do not skip
+ subtree-end))) ; tag not found, continue after end of subtree
+@end lisp
+
+Furthermore you must write a command that uses @code{let} to temporarily
+put this function into the variable @code{org-agenda-skip-function},
+sets the header string for the agenda buffer, and calls the todo-list
+generator while asking for the specific TODO keyword PROJECT. The
+function must also accept one argument MATCH, but it can choose to
+ignore it@footnote{MATCH must be present in case you want to define a
+custom command for producing this special list. Custom commands always
+supply the MATCH argument, but it can be empty if you do not specify it
+while defining the command(@pxref{Custom agenda
+views}).} (as we do in the example below). Here is the example:
+
+@lisp
+(defun my-org-waiting-projects (&optional match)
+ "Produce a list of projects that contain a WAITING tag.
+MATCH is being ignored."
+ (interactive)
+ (let ((org-agenda-skip-function 'my-skip-unless-waiting)
+ (org-agenda-overriding-header "Projects waiting for something: "))
+ ;; make the list
+ (org-todo-list "PROJECT")))
+@end lisp

@cindex thanks
-The beginnings of Org-mode go back to 2003. It was borne out of
-frustration over the user interface of the emacs outline-mode. All I
-wanted was to make working with an outline tree possible without having
-to remember more than 10 commands just for hiding and unhiding parts of
-the outline tree, and to allow to restructure a tree easily. Visibility
-cycling and structure editing were originally implemented in the package
+Org-mode was borne in 2003, out of frustration over the user interface
+of the Emacs outline-mode. I was trying to organize my notes and
+projects, and using Emacs seemed to be the natural way to go. However,
+having to remember eleven different commands with two or three keys per
+command, only to hide and unhide parts of the outline tree, that seemed
+entirely unacceptable to me. Also, when using outlines to take notes, I
+constantly want to restructure the tree, organizing it parallel to my
+thoughts and plans. @emph{Visibility cycling} and @emph{structure
+editing} were originally implemented in the package
@file{outline-magic.el}, but quickly moved to the more general
-@file{org.el}. TODO entries, basic time stamps, and table support were
-added next, and highlight the two main goals that Org-mode still has
-today: To create a new, outline-based, plain text mode with innovative
-and intuitive editing features, and to incorporate project planning
-functionality directly into a notes file.

+planning, the next step was adding @emph{TODO entries}, basic @emph{time

+plain text mode with innovative and intuitive editing features, and to

Since the first release, hundreds of emails to me or on
@code{emacs-orgmode@@gnu.org} have provided a constant stream of bug

-code. Many thanks to everyone who has helped to improve this package.
