Greetings.
I think I have discussed multiline Org macros here before. But I bumped
into the issue again.
One of the most useful properties of LaTeX is \newcommand, which allows
you to reuse document structures. I really, _really_ miss this feature
in Org. Org has #+MACRO, but it is limited to a single line. That is
very inconvenient for any larger structures.
I was thinking (awfully sorry, will stop soon). Could we have multiline
macros, something like
#+BEGIN_MACRO name
#+END_MACRO
where everything between the begin and end would be expanded just like
(single line) macros are right now. With newlines included in the
expansion.
How about it?
Jarmo

Of course, macro are inconvenient for complex structures. They are not
the right tool for the job. You could use Babel for that, e.g.,
#+name: template
#+header: :var x="" y=""
#+header: :results silent
#+begin_src org
$x
$y
#+end_src
#+call: template("line 1", "line 2") :results replace
#+RESULTS:
line 1
line 2

For the record, I think that block syntax is largely overloaded. I'd
rather not introduce a new type of block without a really good reason.
Anyway, is there anything wrong with Babel, as suggested above?

To me, the syntax is a bit tiresome for inline calls,
call_<name>[<inside header arguments>](<arguments>)[<end header arguments>]
You almost always have to tweak the header arguments to get it to work
properly. E.g. I think it prints return values as code by default
(e.g. "=·=").
I wonder if we could allow remote editing of macros like with table
formulas.

This is where macros can shine. You can define a macro expanding to this
template.

This is orthogonal to the issue. Once edited, it sill have to be
inserted in the document as a multi-line macro, which is not possible.

Sure.

Not if we can automatically format lines, which is not at all obvious. It
might be possible with lispy macros, but might not be possible in general.
(Table formula lines can be long, but it's not a problem since they can be
edited in a separate window).
