help regarding babel to set in-buffer specific keybinding

[Thomas Alexander Gerds]

here is a (beginner) question regarding the following org-file with
buffer-local function and keybinding:

,----
| 
| * Lisp header (C-c C-c to activate)
| #+BEGIN_SRC emacs-lisp 
|   (defun blue-file ()
|     (interactive)
|     (org-table-insert-row 'below)
|     (org-table-goto-column 1)
|     (insert (format-time-string "%d.%m.%Y"))
|     (org-table-goto-column 2)
|     (org-table-copy-down 1)
|     (org-table-goto-column 3)
|     (org-table-copy-down 1)
|     (org-table-goto-column 4))
|   (define-key org-mode-map [(meta return)] 'blue-file)
| #+END_SRC
| 
| #+RESULTS:
| : blue-file
| 
| 
| | Date | Staff        | Type        | Name | Value |
| |------+--------------+-------------+------+-------|
| |      | Anders And   | consulting  |      |       |
| |      | Anders And   | supervision |      |       |
| |      | Anders And   | teaching    |      |       |
| |      | Mickey Mouse | consulting  |      |       |
| |      | Mickey Mouse | supervision |      |       |
| |      | Mickey Mouse | teaching    |      |       |
`----

now, I would like to tell org to evaluate the lisp code at startup, when
the org-file is opened. can this be achieved? particularly, is there a
startup special line which tells org to evaluate the lisp src block?  I
could add a suitable function to org-mode-hook, but is this the
recommended way?

also, I would like to make org-mode-map buffer-local ... but certainly
this is not an orgmode question.

suggestions/help are very much appreciated!

Tomy

There is not currently any support for evaluating specific code blocks
on buffer open.  You could move your elisp code into a
buffer-local-variable block (which can house functions) and which are
evaluated when buffers are opened.  I believe all changes made in such
blocks are buffer local, so that may be your best bet.

See [[info:elisp#File%20Local%20Variables][info:elisp#File Local Variables]]
or  http://www.emacswiki.org/emacs/FileLocalVariables

and I would be uncomfortable having code execute automatically upon
visiting an org file...

however, I would imagine it should be possible to add something to
org-mode-hook that would execute a predefined src code block, e.g. maybe
one named "startup" or probably a bit more specific?  I wouldn't know
the babel invocation required, mind you, but I'm others can help here!

Hmmm,
Recently I started to use source code blocks as a kind of init for a
certain task,  set variables,  modify stuff.  That is,  execution of a
source code block once at the beginning, e.g.  after opening an org file.
Thus, I was thinking about automatically execution too.
Would it help if there would be a approval necessary by the user.  A list
of trusted organisation files could be compared to execute a start block
without approval.
Sure there are still possible attack scenarios but that's what you pay for
more comfort ;)
