Hello,
Is it possible to have locally defined CONSTANTS in .tex buffer? What is the
command to update the list of known CONSTANTS since $pi works but I cannot
insert $x to the list of CONSTANTS. See example below
\begin{comment}
#+CONSTANTS: x=458.0
#+ORGTBL: SEND test1 orgtbl-to-latex :splice t :lend ""
| 3.1415927 | #ERROR |
#+TBLFM: @1$1=$pi::@1$2=$x
% $
\end{comment}
I would appreciate a hint.
Thanks.

This works for me. Put you must do `C-c C-c' in the CONSTANTS line
to make changes known to Org-mode. Or kill the buffer and revisit the
file,
that will also make CONSTANTS known.

I am sorry, I did not read this carefully. No, this is currently
not possible in tex and other non-org-mode files.

For sure, there is a better way to implement it, but for now I modified orgtbl-
ctrl-c-ctrl-c function to update org-table-formula-constants-local. This
variable is updated when hitting C-c C-c when being on #+TBLFM line.
(defun orgtbl-ctrl-c-ctrl-c (arg)
"If the cursor is inside a table, realign the table.
If it is a table to be sent away to a receiver, do it.
With prefix arg, also recompute table."
(interactive "P")
(let ((pos (point)) action consts-str consts cst)
(save-excursion
(beginning-of-line 1)
(setq action (cond ((looking-at "[ \t]*#\\+ORGTBL:.*\n[ \t]*|") (match-
end 0))
((looking-at "[ \t]*|") pos)
((looking-at "[ \t]*#\\+TBLFM:") 'recalc))))
(cond
((integerp action)
(goto-char action)
(org-table-maybe-eval-formula)
(if arg
(call-interactively 'org-table-recalculate)
(org-table-maybe-recalculate-line))
(call-interactively 'org-table-align)
(when (orgtbl-send-table 'maybe)
(run-hooks 'orgtbl-after-send-table-hook)))
((eq action 'recalc)
(save-excursion
(goto-char (point-min))
(while (re-search-forward "#\\+CONSTANTS: \\(.*\\)" nil t)
(setq const-str (substring-no-properties (match-string 1)))
(setq consts (append consts (org-split-string const-str "[ \t]+")))
(when consts
(let (e)
(while (setq e (pop consts))
(if (string-match "^\\([a-zA-Z0][_a-zA-Z0-9]*\\)=\\(.*\\)" e)
(push (cons (match-string 1 e) (match-string 2 e)) cst)))
(setq org-table-formula-constants-local cst)))))
(save-excursion
(beginning-of-line 1)
(skip-chars-backward " \r\n\t")
(if (org-at-table-p)
(org-call-with-arg 'org-table-recalculate t))))
(t (let (orgtbl-mode)
(call-interactively (key-binding "\C-c\C-c")))))))

Hi Seweryn,
nice patch, thanks, I have included it with very minor modifications
(mainly anchoring the match to the left margin with spaces).
Thanks!
