;; #+TBLFM: $2='(org-sbe "fibbd" (n $1))

;; NOTE: The quotation marks around the function name, 'fibbd' here,
;; are optional.

;;; Code:

(require 'org-macs)
(unless (version< emacs-version "29")
  (org-assert-version))

(require 'ob-core)
(require 'org-macs)

(defun org-babel-table-truncate-at-newline (string)
  "Replace newline character with ellipses.
If STRING ends in a newline character, then remove the newline
character and replace it with ellipses."
  (if (and (stringp string) (string-match "[\n\r]\\(.\\)?" string))
      (concat (substring string 0 (match-beginning 0))
	      (when (match-string 1 string) "..."))
    string))

(defmacro org-sbe (source-block &rest variables)
  "Return the results of calling SOURCE-BLOCK with VARIABLES.

Each element of VARIABLES should be a list of two elements: the
first element is the name of the variable and second element is a
string of its value.

So this `org-sbe' construct

 (org-sbe \"source-block\" (n $2) (m 3))

is the equivalent of the following source code block:

 #+begin_src emacs-lisp :var results=source-block(n=val_at_col_2, m=3) \\
     :results silent
 results
 #+end_src

NOTE: The quotation marks around the function name,
`source-block', are optional.

NOTE: By default, string variable names are interpreted as
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.
