Is it possible to get syntax highlight for HTML code within a #+BEGIN_EXPORT HTML environment block in org-mode?

I know it is possible to highlight HTML within a #+BEGIN_SRC block using ob-browser. Is there a way to "extend" such highlighting to other blocks as well?

    It sounds like this might not be exactly what you want, but if you set (setq org-src-fontify-natively t) in your config, then html in a #+BEGIN_SRC html block should have highlighting. There is a nice setup here for dealing with org-mode source code blocks: github.com/danielmai/.emacs.d/blob/master/…

  • Yp, within #+BEGIN_SRC is not a problem... I was wondering about #+BEGIN_HTML. But thanks for the link

The problem lies on the arbitrariness with which Org Mode deals with case sensitivity. I was used to having a #+BEGIN_HTML block in Org Mode 8, and that didn't trigger the syntax highlighting. Had I used lowercases as in #+begin_html, things might have looked different.

Now, with Org Mode 9, one can get HTML highlight with any of:

#+begin_export html
<div>  
</div>
#+end_export

#+BEGIN_EXPORT html
<div>  
</div>
#+END_EXPORT

But not with: 

#+BEGIN_EXPORT HTML
<div>  
</div>
#+END_EXPORT

Here's a screenshot:

  • This does not appear to work in the current version, I get no highlighting regardless how I type it. Any idea for how it can be made to work, or where in the Org Mode source I should look to figure it out myself? I'm running Org Mode from the git repo, org-version currently reports version 9.7-pre (release_9.6.7-555-ga1ef64).

  • Cannot reproduce on 9.6.1. Did it use to work before and stopped working now? I get syntax highlight without issues. With that said, a lot is currently changing under the hood on org-mode and the org element API, and I've had org-roam breaking and some org-exports as well. Would not exclude the possibility of a bug
