+;;; Commentary:
+;;
+;; This module prettifies the display of org-babel source blocks.
+;; Notably it hides the src_lang{code} part for inline source blocks
+;; after execution. The code block can be still be interacted with by
+;; placing the cursor in front of the result block, on the first {.
+;;
+;;; Code:
+
+(defvar org-babel-prettify-mode nil)
+
+(defvar org-babel-prettify--keywords '(("\\(src_[^{
+ ]*{.*?}[
+ ]{{{results(\\)\\(.*?\\))}}}" (1 (org-babel-prettify--compose-symbol))))
+  "Keyword list that is added to `font-lock-keywords` when
+  entering org-babel-prettify-mode.")
+
+(defun org-babel-prettify--compose-symbol ()
+  (let* ((pre_start (match-beginning 1))
+	 (pre_end   (match-end 1))

+	 (post_end   (match-end 0)))
+    (put-text-property pre_start pre_end 'display "{{{" nil)
