Hi Rainer,

I like to use file local variables [1] to do per-file Org-mode
configuration and customization this is an easy way to set the local
value of a variable every time the file is opened.

I think you could use file local variables to evaluate arbitrary elisp
when a file is opened in which case you could evaluate a named code
block with something like `(sbe code-block-name)'.

Sounds interesting.

So to set the post-tangle-hook, I tried the following:

# -*- eval: (add-hook 'org-babel-post-tangle-hook( lambda () (call-process-shell-command "./postTangleScript.sh" nil 0 nil); -*-

But it did not work - I have no idea, what I'm missing - eval should evaluate the following _expression_, which should set the post-tangle-hook.

Your suggestion, to evaluate a code block after opening, sounds very interesting - could you give me a very short example?

Thanks, and sorry for my lack of elisp understanding - it has not improved much...

Rainer
