Re: How to get a block’s contents by name

I would do this:

#+BEGIN_SRC emacs-lisp
(defun org-get-named-block-contents (name)
  (save-excursion
    (goto-char (point-min))
    (let ((regexp (org-babel-named-src-block-regexp-for-name name)))
      (or (and (looking-at regexp)
      (progn (goto-char (match-beginning 1))
     (line-beginning-position)))
 (ignore-errors (org-next-block 1 nil regexp)))
      (org-babel-expand-src-block))))
#+END_SRC

This is basically what org-babel-find-named-block does, with the
(org-babel-expand-src-block) return instead of the position. It avoids the
double save-excursion.

This is probably faster than any alternative that involves parsing the
buffer, especially for large buffers.
