Define org mode macro with line breaks

Question

It is possible to define a macro in an org file as follow:

#+MACRO: macroname 

Is it possi

Answer 1

Not only is this possible, it's quite easy to do. You just need to be creative about how you insert the newline. I make use of Org Babel to hack the macros. The following works for me:

#+MACRO: newline   src_emacs-lisp[:results raw]{"\n"}
#+MACRO: macroname line 1 of macro {{{newline}}}line 2 of macro

So, given this document:

#+MACRO: newline    src_emacs-lisp[:results raw]{"\n"}
#+MACRO: macroname line 1 of macro {{{newline}}}line 2 of macro

{{{macroname}}}

Exporting to Org mode gives the following

# Created 2015-11-03 Tue 15:27
#+TITLE: 
#+AUTHOR:
#+MACRO: newline    src_emacs-lisp[:results raw]{"\n"}
#+MACRO: macroname line 1 of macro {{{newline}}}line 2 of macro

line 1 of macro 
line 2 of macro

You just have to be aware that some export formats will transform that newline to a single line when it wraps the text. So, you probably want something like this to get two paragraphs:

#+MACRO: newline   src_emacs-lisp[:results raw]{"\n"}
#+MACRO: macroname line 1 of macro {{{newline}}} {{{newline}}}line 2 of macro
