Dear orgmode users
as the best way to submit a Babel support for a new language is this
mailing list, I submit this partial support for SAS
language (using ESS).
This is partial as only few header arguments are supported
:results output
:output graphics
:session
arguments are supported but one of the most important, :output value, is
not supported (as I am not able to figure out what does it really mean
with SAS).
I am not proud of it but I have added a
:results odsgraphics
for odsgraphics (which are different from sas/graph classical graphics).
If someone is interested in that support, please see the attached file
(as I don't actually know anything about the orgmode mailing list
policy about attached file, I hope it will be still attached...)
Comments and suggestions are welcome.
Best regards
Pierre-Andre

;;; Commentary:
;; The file provides Org-Babel support for evaluating sas code. It is
;; basically result of find-and-replace "sas" for "julia" in
;; ob-julia.el by G. Jay Kerns.
;; 1) Parameter ":results output" needs a
;; to give the right filename for SAS in the Parameter ":results value"
;; does not work (I'm not sure it makes sense or is useful). Parameter
;; ":session" works with default value using ESS
;;
;;; Requirements:
;; Sas: http://sas.com
;; ESS: http://ess.r-project.org
;;; Code:
(require 'ob)
(require 'cl-lib)
(declare-function orgtbl-to-csv "org-table" (table params))
(declare-function sas "ext:ess-sas" ( start-args))
(declare-function inferior-ess-send-string "ext:ess-inf" ())

(declare-function ess-eval-buffer "ext:ess-inf" (vis))
