multi-export-target macros

[mdsib]

I'm working on an org file that will eventually export to html and pdf/latex.

If anyone's interested, I can add these sorts of macros on here, and perhaps give them some better names.

#+MACRO: begin_main (eval (begin-main-macro))
#+MACRO: end_main (eval (end-main-macro))
#+MACRO: begin_aside (eval (begin-aside-macro))
#+MACRO: end_aside (eval (end-aside-macro))
#+begin_src elisp :exports results :results silent
  (defun begin-main-macro ()
    (pcase org-export-current-backend
      ('latex "\\begin{minipage}[t]{0.5\\textwidth}")
      ('html "@@html:<div class='main'>@@")
      (t "")))
  (defun end-main-macro ()
    (pcase org-export-current-backend
      ('latex "\\end{minipage}")
      ('html "@@html:</div>@@")
      (t "")))
  (defun begin-aside-macro ()
    (pcase org-export-current-backend
      ('latex "\\begin{minipage}[t]{0.2\\textwidth}")
      ('html "@@html:<div class='aside'>@@")
      (t "")))
  (defun end-aside-macro ()
    (pcase org-export-current-backend
      ('latex "\\end{minipage}")
      ('html "@@html:</div>@@")
      (t "")))
#+end_src

Usage:

{{{begin_main}}}
Main section stuff goes here.
{{{end_main}}}
{{{begin_aside}}}
Aside section stuff goes here.
{{{end_aside}}}

You have to run the src block with C-c C-c before exporting. I think there's an option to do this automatically, but I haven't set that up.
