;;; 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.

Such a file can be imported into usual spreadsheet programs.

FILE can be the output file name.  If not given, it will be taken
from a TABLE_EXPORT_FILE property in the current entry or higher

name.  FORMAT can be an export format, of the same kind as it
used when `orgtbl-mode' sends a table in a different format.

The command suggests a format depending on TABLE_EXPORT_FORMAT,
whether it is set locally or up in the hierarchy, then on the

  "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)
  "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.
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

           The format may also be a function that formats its one argument.

:efmt      Format for transforming numbers with exponentials.  The format
           should have %s twice for inserting mantissa and exponent, for
           example \"%s\\\\times10^{%s}\".  LaTeX default is \"%s\\\\,(%s)\".
           This may also be a property list with column numbers and formats.
           The format may also be a function that formats its two arguments.

:llend     If you find too much space below the last line of a table,
