Macros or properties in source blocks

Macros or properties in source blocks

[Gary Oberbrunner]

I'd like to have either a macro or a property that controls some behavior
of an org-mode babel file:

#+PROPERTY: report_type All

and use that property inline: {{{property(report_type)}}} and in a source
block:

#+NAME: rtype
#+BEGIN_SRC emacs-lisp :results value
{{{property(report_type)}}}
#+END_SRC

And use that source block:

The report type is call_rtype()[:results raw]

But this doesn't work, I get "Symbol's value as variable is void:
{{{property

Is there any way to interpolate macros or properties into a source block
like this? Or is there a better way for me to set org-mode "global
variables" at the top of my file?

BUT THIS DOES:

--8<---------------cut here---------------start------------->8---

#+NAME: rtype
#+header: :var prop=(org-entry-get (point) "report_type" t)
#+BEGIN_SRC emacs-lisp
prop
#+END_SRC

And use that source block:

The report type is call_rtype()[:results raw]

--8<---------------cut here---------------end--------------->8---

HTH,

Though, I don't understand either why your example did not work, as --
during the export process -- macros are supposed to be expanded before
Babel code be evaluated.

There must be some restriction, then, on which part of a document
a macro can reside in.

Best regards,

According to the manual

  These references, called macros, can be inserted anywhere Org markup is
  recognized: paragraphs, headlines, verse blocks, tables cells and lists.

The innards of a source block do not belong to Org.
