automatically run code blocks when loading an org-mode document

automatically run code blocks when loading an org-mode document

Hi! When I load the document below, I first need to manually evaluate the
code block before I can use the links. I would like the code block to be
automatically evaluated when I load the document, making the links usable
at once.

Is there some clever in-buffer-setting I can use, to specify that I want
the block called on loading, some kind of post-load hook?

#+BEGIN_SRC emacs-lisp
(defun handy-stuff(arg)
  (message arg))
#+END_SRC

[[elisp:(handy-stuff "foo")][foo]]
[[elisp:(handy-stuff "bar")][bar]]

--8<---------------cut here---------------start------------->8---
#  -*- find-file-hook: org-babel-execute-buffer -*-
#+BEGIN_SRC emacs-lisp
(defun handy-stuff(arg)
 (message arg))
#+END_SRC

[[elisp:(handy-stuff "foo")][foo]]
[[elisp:(handy-stuff "bar")][bar]]

--8<---------------cut here---------------end--------------->8---

will do that (but you get a question re. "safe" local variables when
you open the file). It also executes *every* code block in the buffer
which you might not want to do (although it does not matter in this
case).

For the OP, instead of evaluating every code block, it is possible to
evaluate just one code block.  I have:

# Local Variables:
# eval: (esf/execute-startup-block)
# End:

in my org file with

#+begin_src emacs-lisp
  (defun esf/execute-startup-block ()
    (interactive)
    (org-babel-goto-named-src-block "startup")
    (org-babel-execute-src-block))
#+end_src

and so only a block named startup will be executed.

​That's a better solution indeed.​
