Eric,
thanks for the answer. another "#+begin_src org" question. it appears
that only *string* values are allowed for any :var that are defined
(i.e., ':var bar="foo"', and *not* ':var bar=3'). since i'm not 100%
sure of the semantics, maybe this is desired.
if one *should* be allowed to pass in, e.g., tables, numbers, etc., then
maybe org-babel-expand-body:org in ob-org.el wants to change from the
current
----
(defun org-babel-expand-body:org (body params)
(dolist (var (mapcar #'cdr (org-babel-get-header params :var)))
(setq body (replace-regexp-in-string
(regexp-quote (format "$%s" (car var))) (cdr var) body
nil 'literal)))
body)
----
to something like this
----
(defun org-babel-expand-body:org (body params)
(dolist (var (mapcar #'cdr (org-babel-get-header params :var)))
(setq body (replace-regexp-in-string
(regexp-quote (format "$%s" (car var)))
(if (stringp (cdr var))
(cdr var)
(format "%s" (prin1 (cdr var))))
body nil 'literal)))
body)
----
(as otherwise replace-regexp-in-string notices that (cdr var) is *not* a
string, and attempts to execute it.)
maybe^2 it would make even more sense to use the "#+begin_src
emacs-lisp" equivalent routine from ob-emacs-lisp.el as a template?
----
(defun org-babel-expand-body:emacs-lisp (body params)
"Expand BODY according to PARAMS, return the expanded body."
(let* ((vars (mapcar #'cdr (org-babel-get-header params :var)))
(result-params (cdr (assoc :result-params params)))
(print-level nil) (print-length nil)
(body (if (> (length vars) 0)
(concat "(let ("
(mapconcat
(lambda (var)
(format "%S" (print `(,(car var) ',(cdr var)))))
vars "\n ")
")\n" body "\n)")
(concat body "\n"))))
(if (or (member "code" result-params)
(member "pp" result-params))
(concat "(pp " body ")") body)))
----
(my elisp isn't strong enough to evaluate this.)
cheers, Greg
