Hi,
I am new to emacs and orgmode. I spent the last couple days reading most
of the docs before diving in, but I didn't see anywhere how I could have a
macro that instead of replacing the macro with lisp code, calls an
external program instead.
Something like:
#+MACRO: func call /home/josh/mybinary $1
{{{func(Text Argument)}}}
and this would be setup to call an external program and the output of the
program would replace the macro on export.
/home/josh/mybinary "Text Argument"
Thanks!
Josh

You could maybe do something along the lines of
#+macro: func (eval (shell-command (concat "/home/josh/mybinary " "$1")))
(untested).

Thanks! This is very helpful.
I have a related question. How can I run an external program right before
Export that takes as input the current buffer and prints out to stdout an
updated version of the org file that then is exported? Basically I want to
pipe the org file through a filter that is an external program before it
is exported.
Thanks in advance!

Probably one of `org-export-before-parsing-hook' or
`org-export-before-processing-hook' is where you'd hang a custom
function that does this.

See the variables org-export-before-processing-hook and
org-export-before-parsing-hook.
You can put something like this in a noexport tagged build heading in
your document. Here I run head on the org-file to just get the first
three lines. you can replace that with your external filter.:
#+BEGIN_SRC emacs-lisp
(let ((org-export-before-parsing-hook '((lambda (backend)
"lightly tested"
(let ((new-doc (shell-command-to-string (format "head -n 3 \"%s\"" (buffer-file-name)))))
(erase-buffer)
(insert new-doc))))))
(org-open-file (org-html-export-to-html)))
#+END_SRC

I do wonder if you're asking an XY problem, especially after reading your follow-up question about running an entire Org file through a pre-filter.
Why does it have to be a macro that you call? Why not #+NAME:'d Babel code block, which can (presumably) run any program you want.
-k.

Thanks Ken.
Yes, at first I was trying to accomplish my task with Macros, but after
finding out that I could run the whole Org file through a pre-filter, I
realized that this would be a much cleaner and easier way rather than
having multiple types of macros or code blocks. So now I'm trying to
figure out how to attach an external program to
`org-export-before-parsing-hook' or `org-export-before-processing-hook' to
pipe the entire Org file through...
