;;; Commentary:
|
|
|
|
;; Babel support for evaluating processing source code.
|
|
;;
|
|
;; This differs from most standard languages in that
|
|
;;
|
|
;; 1) there is no such thing as a "session" in processing
|
|
;;
|
|
;; 2) results can only be exported as html; in this case, the
|
|
;; processing code is embedded via a file into a javascript block
|
|
;; using the processing.js module; the script then draws the
|
|
;; resulting output when the web page is viewed in a browser; note
|
|
;; that the user is responsible for making sure that processing.js
|
|
;; is available on the website
|
|
;;
|
|
;; 3) it is possible to interactively view the sketch of the
|
|
;; Processing code block via Processing 2.0 Emacs mode, using
|
|
;; `org-babel-processing-view-sketch'. You can bind this command
|
|
;; to, e.g., C-c C-v C-k with
|
|
;;
|
|
;; (define-key org-babel-map (kbd "C-k") 'org-babel-processing-view-sketch)
