Hi. Guys.

On emacs 27.1 emacs on the tty renders pretty fine.

[Message part 3 (text/plain, inline)]

On emacs 28.0.50 the colors has changed (read quality was better on 27)

So I guess this is about highlighting in cc-mode?  Alan, any idea if
anything has changed in this area?

Hello, rrandresf.

Firstly, sorry about missing your bug report last December.

Secondly, it's great to see somebody else using the Linux tty!

It looks like the fontification was unfinished on that screen.  For
example, strings and comments get fontified, but the variable
declarations didn't.  I hope that was a bug in CC Mode which has long
been fixed.  When that happens, there is often an error message in the
*Messages* buffer, which you can see with C-h e.

Was there anything else about the reduction in quality you mention?  I
think your yellow strings was something you configured yourself, for
example.

Is the problem still there in the savannah master branch, or what has
now become the Emacs-28 release branch?

Right. Alan. tty is quick and awesome. Excellent for the eyes.

I have just checked. That it has been fixed on the emacs-28 release
branch. So I think the bug could be closed. Thanks for work guys.
