Hi everyone:

Is there any way to make something like this actually work?

#+title:test
#+macro: num 50

#+name: numbers
#+begin_src emacs-lisp no-export
40
#+end_src

#+begin_export html

the result is {{{num}}}

another result is <<numbers>>
#+end_export

I did this and it didn't work (but the one outside the export block did):

#+title:test

#+name: numbers
#+begin_src emacs-lisp :exports none
40
#+end_src

#+begin_export html

the result is call_numbers()

#+end_export

the result outside an export block is call_numbers()

The export block provides text that is to be used "as is" by the html backend. So, "call_numbers()" is treated as html.

You need to construct the export block programmatically. Maybe something like 

#+begin_src emacs-lisp :results html :exports results :var num=numbers()
   (format "the result is %d" num )
#+end_src

 
HTH,

Thanks for that Chuck.   It would seem a lot cleaner if there was a hook or
something one could run that would just expand macros in export blocks
before exporting them.

When I look at the doc string for (org-macro-replace-all) it says:


*Optional argument KEYWORDS, when non-nil is a list of keywords,*
*as strings, where macro expansion is allowed.*

I tried passing it '("export-block") but it didn't work, but it seems like
something like that should be close.

This whole area of org documentation seems pretty obtuse, with few examples.

Check out export filters in 13.17 Advanced Export Configuration

By default, we cannot allow Org syntax inside export blocks because it
can interfere with the exported format syntax.

KEYWORDS argument is listing the "keyword" syntactic elements. Your
export block is an "export block" element where macro expansion cannot
work by design.

Could you please point out which particular part of org documentation is
lacking?

The problem with that is when I export I get <p> </p> both above and below
the result (even though I added :results output raw) and I need it inline
plus it's changing my angle brackets to &gt and &lt (I'm trying to generate
php code).

Any idea how to fix that?

Use inline src block or an inline call to the src block.

Does this help?

Adding this to your example:

Here is an inline code src_emacs-lisp[
:results html :exports results :var num=numbers()]{
(format "the result is %d." num )} End.


Produces a paragraph:

<p>
Here is an inline code the result is 40. End.
</p>

Did you browse worg? Especially this:

https://orgmode.org/worg/org-contrib/babel/index.html


Agree that documentation is a WIP and export blocks are mentioned only in reference to specific exporters, so there is that.
