Hello,
how can I concatenate header args? Let's assume I have an Org structure
like follows:
* foo
:PROPERTIES:
:header-args: :flags -Wall
:END:
** bar
#+begin_src C :flags -lm
#+end_src
Now I want the code to be compiled with -Wall _and_ -lm.
Regards
hmw

I am pretty sure this isn't possible. The headers get overridden by the
most local settings. There isn't a way to concatenate them. In some cases
there isn't a way to figure out what you want, e.g. if a heading property
said ":tangle no" and your header said ":tangle yes" it would not make
sense to concatenate these to ":tangle no yes".
I think you have to add -Wall to the src header.

hm, I could think of a special syntax, like :tangle results in the
current behaviour and :+table concats values. That way it's up to the
user to express what she wants.

Hm, the property values can be functions that get evaluated to get the
actual property values, can't it? I'm not sure though if something like
:flags (get-em "flags" '("-more" "-values")) is so much nicer to write.
Maybe it is, esp. if you want to change the base flags for a ton of
items. Today is teaching tuesday (even if it's wednesday ;)), so I'm a
bit short on time. But I will try that approach later this week and see
where that leads to.
Thanks

not too nice, but works good enough for me ;).
(defun hmw/org-prop-append(prop value)
(format "%s %s" value (cdr (assq prop
(car (org-babel-params-from-properties))))))
(defalias 'A 'hmw/org-prop-append)
* foo
:PROPERTIES:
:header-args: :flags -Wall
:END:
** bar
#+begin_src C :flags (A :flags "-lm")
#+end_src
