 ; Requires and autoloads

(require 'noweb-mode)

 ; Variables

(defvar ess-noweb-use-font-lock window-system
  "Set to t if you want to use font-locking in ESS noweb buffers.")

;; this helps with XEmacs barfing, sigh...
(setq global-font-lock-mode t)

(if ess-noweb-use-font-lock
     (require 'noweb-font-lock-mode))

 ; Functions

;;*;; Code Chunk evaluation.

(defun ess-eval-chunk (vis)
  "Tangle the current chunk and send it to the inferior ESS process.
Arg has same meaning as for `ess-eval-region'."

;;*;; Thread code chunk evaluation

;;;
;;; Threads are code chunks which fit into the same "buffer" (I'm (AJR)
;;; abusing terminology, but what I mean is things like:
;;; <<thing1>>=
;;;   code for thing1
;;; @
;;; Documentation
;;; <<thing1>>=
;;;   continuing code for thing1
;;; @
