[babel] set post tangle hook on per file basis - evalu

[Rainer M Krug]

Hi

for different files, I put different things in the post-tangle hook. At tha
moment, I have an emacs-lisp code block, which I evaluate before I tangle,
but I forget this sometimes - so y question: is it possible (and think to
remember that it is, but I can't find how) to evaluate a source code block
upon opening of the file, or set the org-babel-post-tangle-hook in a
different way upon opening of the org file?

The code block I am using at the moment is:

** Evaluate to run post tangle script
#+begin_src emacs-lisp :results silent :tangle no :exports none
  (add-hook 'org-babel-post-tangle-hook
            (
             lambda ()
                    (call-process-shell-command "./postTangleScript.sh" nil
0 nil)
                    )
            )
#+end_src

Thanks,

Rainer

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

maybe try something like the following

# -*- org-babel-post-tangle-hook: '(my-tangle-hook-function) -*-

where `my-tangle-hook-function' is defined in your .emacs config.

The info link I posted should explain how to evaluate a snippet of
elisp, once you have that working (you could test with simple calls to
the `message' function) you can use the `sbe' function (see it's
documentation) to evaluate named code blocks.

Good idea - I'll try that - thanks.

Thanks, I'll try it out,
