Subject: looking for a macro eval workaround (9.1 vs 9.2 and +) for export backend test
Date: Sat, 21 Nov 2020 11:56:33 +0100	[thread overview]
Message-ID: <20201121105633.kgwzxc2l6oo5yeau@localhost.localdomain> (raw)

I have a *lot* of org files with a macro =if-backend= which enables me
to decide what to export depending on the backend :

#+begin_src org
  #+macro: if-backend (eval (if (org-export-derived-backend-p org-export-current-backend '$1) "$2"))

For instance, I use it to include =\hfill= in LaTeX family export
engines but not in others (html for instance) :

#+begin_src org
  #+macro: hfill {{{if-backend(latex, \\hfill{} )}}}

I generally use emacs 26.3 as distributed by Debian bullseyes (which
offer org-mode version 9.1.9).

On another box I need to work with a more recent org-mode, precisely

In that environment, due to an incompatible change introduced by
[[https://orgmode.org/Changes_old.html#outline-container-org003add6][release 9.2]] the same macro has to be written in a different way :

#+begin_src org
  #+macro: if-backend (eval (if (org-export-derived-backend-p org-export-current-backend (intern $1)) $2))

And thus I need to change also the macro using it, for instance the
=hfill= macro has to be written that way :

#+begin_src org
  #+macro: hfill {{{if-backend(latex, \hfill{} )}}}

For now I need to work on the same files in these two different environment.

Do anyone have an idea on how to be able whether to define the
=if-backend= in a way that it can work in both org versions or if
there is a way to define these macro in different ways depending on
org version?

I would like to let the definitions in org files and not in emacs init
