Hi,
I'm playing a bit with org-element for org-contacts and I wanted to know
what is the prefered way to change an element.
For example, ATM, when I want to change an element property to add a new
value, I do:
#+BEGIN_SRC emacs-lisp
(org-entry-put nil property
(concat (org-entry-get nil property)
" " new-value))
#+END_SRC
Is it the correct way? IMHO it would be nicer if we could modify an
object created by the new parser and write it back but I don't think
it is possible (yet?).
Regards,

See `org-element-put-property' and friends.

I've tried to use `org-element-put-property' but it only modifies the
object in memory, not the element in the file. Is there a way to write
the object into a file?

I misread your question.
"org-element.el" doesn't provide functions to modify the buffer, but you
may use `org-element-interpret-data' to create Org syntax from an
object.
You may also want to have a look at org-sync.el.

The Org fragment
\[
r = a
+ b
- c
\]
gets interpreted as something strange with a list inbetween. Thus it gets
exported as:
$\backslash$[
r = a
\begin{itemize}
\item b
\item c
\end{itemize}
$\backslash$]
How is one supposed to write (longer) equations out on multiple lines (leaving
the operators behind on the previous line obviously works, but is ugly)?

Achim.

I use LaTeX blocks. So your example would translate to:
#+begin_latex
\begin{equation}
r = a
+ b
- c
\end{equation}
#+begin_latex
With easy templates, entering blocks is trivial (<l for LaTeX blocks).
Hope this helps,

This is a bit different from what the OP is asking for. A LaTeX block
will only be exported by a latex (or derived) back-end. On the other
hand, \[1+1\] may be exported by any back-end (for example using mathjax
in html).
Anyway, the equivalent would be a LaTeX environment:
\begin{equation*}
r = a
+ b
- c
\end{equation*}

Ah! I did not realise that \[..\] was also interpreted by mathjax.
Thanks for pointing it out.

Typo on my part. :-p

Of course, the next question is whether we want to force \[ .. \]
equations to be inlined (with no newline inside) or not. But I let
Nicolas ask and answer this question :)

Sure, but then the equation would only be exported for LaTeX
and I would need to copy the same thing just again for
HTML export.
I didn't put a [Bug] tag on the OP on purpose, since I don't
really know what's officially supported or not w.r.t. LaTeX
fragments. But it seems that proper support of multi-line
LaTeX fragments (and count this as a "yes" vote) then parsing
needs to take into account that there can't be any Org elements
inside them.

Achim.
