Hello,
I want to export to different output formats. Trouble is the way ox-gfm
exports images. So I thought, hm, why not utilise macros to abstract away
the differences. Well, that escalated quickly:
#+macro: img_gfm (eval (concat "#+begin_export md\n![img](" $1 " \"" $2 "\")\n*Abb.: " $2 "* (Quelle: " $3 ")\n#+end_export"))
#+macro: img_latex (eval "foobar")
# Image export for Github flavoured markdown
# $1 path to image
# $2 caption
# $3 source
#+macro: img (eval (cl-case org-export-current-backend ('gfm (concat "{{{img_gfm(" $1 "," $2 "," $3")}}}")) ('latex "{{{img_latex}}}") (t "barfoo")))
{{{img(./foo, foo, barfoo)}}}
That kind of works (and breaks if I want commas in the caption), but is
ugly as... and doesn't get better if I implement the other output formats.
Maybe syntax like @@latex: ...@@ would help. But no, I think that is
defined in the specific backends, not as a general mechanism.
So, how can I do it better?
All the best,
hmw

Re: commas. See 13.5 Macro Replacement
(1) Since commas separate the arguments, commas within arguments have
to be escaped with the backslash character. So only those backslash
characters before a comma need escaping with another backslash
character.

Agree. The proper way to implement this is special blocks + custom
export filter that will take care about backend selection.
Also, see https://list.orgmode.org/orgmode/87y1yr9gbl.fsf@gmail.com/

You can have multiple export blocks---one for each backend.

I found that shortly after posting. Works as expected.

Ah, that looks promising.
Thank you!
