Re: [Pre-PATCH] Overhaul of the LaTeX preview system

in email in Emacs and gmail works better for that).

If I remember correctly, when I run the test I had precompilation turned
off, because with it =lualatex= didn't work, but the diagnostics kept
thinking it was on. Even so, it is currently disabled.

All my relevant configuration was attached in my previous message. If it
helps, my complete Emacs configuration resides at
https://github.com/kchousos/Emacs/blob/master/Emacs.org. The only
noteworthy thing I can think of is that i use Wayland. Also, my Emacs'
version is =29.0.90= and found at
https://copr.fedorainfracloud.org/coprs/majore-biscuit/Emacs-29/. After
that, the steps were the following:

1. Use TEC's org-mode =dev= branch, up to the =---NOPUSH PERSONAL
   DIVIDER---= commit.
2. Set some config options, which can be in the above link.
3. Test the new features.
4. When a latex fragment contained an error, its color would turn red,
   but no popup would appear on hover, or ever for that matter.

   My temporary solution is to directly check the =*Org Preview LaTeX
   Output*= buffer.

That's too bad, it looked really neat and useful.

I noticed that but as I said above, I already use that branch. Perhaps
the bug with the error popups and this are related? After all, both have
to do with popups. Also it is important to note that I have already set
the configuration variables that are relevant to the /live/ preview (at
least those that I could find).


All in all this is a huge improvement and a quality-of-life upgrade for
all org-mode users. Thank you both for your work.
