Happily exporting LaTeX, now want to export to text and HTML, can't figure how to handle latex markup

Good morning,

I'm happily exporting an Org-Mode document to LaTeX using the nifty
`letterine' package. An example is attached. Writing using it has been
so fun that naturally now I want to export it both to text and HTML.
My source document looks like this for reference and all of this works
fine:

> start
#+TITLE: A Poem Title
#+AUTHOR:
#+DATE:
#+OPTIONS: num:nil
#+LATEX: \pagenumbering{gobble}

#+BEGIN_CENTER
@@latex:\lettrine[lines=1]{T}{this}@@ is line 1.

@@latex:\lettrine[lines=1]{H}{ere}@@ is line 2.

@@latex:\lettrine[lines=1]{O}{ver}@@ there is line 3.
#+END_CENTER
> end

Now I'm left be wondering how I can using a single document and export
it correctly to LaTeX, HTML and text. Here are some ideas I came up
with:

- Write the same line two times, one for each exporter. Redundant but
it would work.
- Use a source block that takes a line of text, checks the type of
exporter running, and returns an appropriate markup then on export it
works right.
- Maybe there is a macro for this?
- I'm out of ideas

My Internet search results found a lot of answers about easy stuff.
However this article

https://emacs.stackexchange.com/questions/18636/create-a-custom-block-in-org-mode-that-exports-to-latex-and-html

looked interesting. I haven't started coding anything up yet and I
wanted to talk to you before that.

Thank you.

Putting together a macro seems like the best option.  Recall that you can use elisp in macros by placing it between `(eval’ and `)', so the following emits “def’ in all but latex exports and “abc” for latex.

#+BEGIN_SRC emacs-lisp
(defun foo (a b) (if (eq 'latex org-export-current-backend) a b))
#+END_SRC


#+MACRO: bar (eval (foo $1 $2))


{{{bar("abc" "def")}}}

Yes I found this nice piece of code  

It switches to svg if backend is html and to raw latex if backend is
latex. You only have to tweak it your needs.

#+header: :file (by-backend (html "tree.svg") (t 'nil))
#+header: :imagemagick
#+header: :results (by-backend (pdf "latex") (t "raw"))
#+begin_src latex
  \usetikzlibrary{trees}
  \begin{tikzpicture}
    \node [circle, draw, fill=red!20] at (0,0) {1}
    child { node [circle, draw, fill=blue!30] {2}
      child { node [circle, draw, fill=green!30] {3} }
      child { node [circle, draw, fill=yellow!30] {4} }};
  \end{tikzpicture}
#+end_src

* COMMENT setup
#+begin_src emacs-lisp :results silent
  (setq org-babel-latex-htlatex "htlatex")
  (defmacro by-backend (&rest body)
    `(case (if (boundp 'backend) (org-export-backend-name backend) nil) ,@body))
#+end_src

I think this is obsolete. It fails on org-9.0.9. What version of org are you using? 

In any case replacing the ~(if ...)~ by ~org-export-current-backend~ will fix it.

Another case were adding dates to Worg entries might help.

Thank you. That helps a lot.
