f39 emacs strange behavior?

[Tom Horsley]

I have by no means finished tweaking my fedora 39 boot partition,
but the last time I was booted there, emacs was a complete mess.

It seemed to take forever to respond to keystrokes. Scrolling the
screen would leave random characters in various places which would
disappear if I moved the cursor over them. Probably other weirdness
I didn't figure out.

Anyone else seen this?

I've used alternatives to make emacs-lucid the default. I'll see
if it works better then next time I boot f39...

Did you have any better luck with this. Upgrading to Fedora 39 appears to have made my Emacs unusable in that I can no longer open any existing file.

Right, now, trying my luck with nvim for writing this email (because mutt for me is linked to an editor, in my case, it was emacs).

Best wishes,

Working fine on five separate installs using x11. One install didn't 
have the circular links through /etc/alternatives for whatever they are 
worth

FWIW, you may want to try `mg` as a backup editor for Emacs. If you're 
used to Emacs key-bindings, it's sure to be more familiar. When I used 
mutt more regularly I set mg as my fallback for times when I hadn't yet 
fired up Emacs and done `M-x server-start`:

set editor = 'emacsclient --alternate-editor mg'

Thanks, Ben! I am more or less finding my way around nvim, but I have
not yet figured out two things yet.

I loved the autoformatting feature of C, etc in emacs. Basically as I
typed, things would get formatted. And I have not really been able to
figure out if that is possible here (automagically, without pressing any
key combination).

The other thing I will look at more carefully this weekend is to figure
out a way to reliably highlight a area with my mouse left button and
then paste it with my second mouse button (the wheel). Inside nvim, it
is largely not reliable (with workarounds in many cases, but with key
combinations) and I can not quite figure out why it is not. In the old
days before DEs, the idea of highlight and paste (rather than use
whatever key combination) is something I really got used to.

Many thanks and best wishes,
Ranjan

I use gvim (graphical vim), so this may or may not be applicable:

It can recognise various coding formats and highlight the sections in
colours, so there's potential for further automation.  I haven't tried
to find any auto-formatting, beyond its basic auto-indenting (which
just starts the next line at the same indent as the current line, no
fancy nesting).

A quick look through google suggests there's some add-on that can do
that.  Though I got the feeling it was a post-processing tool, rather
than an as-you-type thing.

I can cut and paste with the mouse, but if you're not in insert
(typing) mode, the results can take you by surprise.  Also, you need to
put the cursor where you want the paste to be inserted before you paste
the contents of the buffer.

I have no particular experience with neovim, but if you've abandoned
hope of getting back to Emacs, I'm fairly sure that vim (and gvim) can
do a decent job of autoformatting with some configuration -- or at
least, as Tim notes, basic auto-indentation out of the box. With C, your
mileage may vary depending on your coding style.

You can also use the mouse with vim in most terminals. Try

:set mouse=a

For more info, do :help mouse

Lastly, I'd be remiss not to mention the `joe` editor, which has an
emacs-compatibility mode that can be started with `jmacs`.

dnf info joe

Here, I've done fresh installs of F39 Workstation on two systems and used
emacs to
make notes and run my usual "smoke" tests.  I'm using Wayland on both
instances.
One system has Intel integrated graphics, the other is a late 2012 iMac
with Nvidia and
is running on nouveau.

I just tried to use "emacs -nw" in an ssh terminal session running in a
WSL2 Debian and
get dark green and blue text on black background and some normal emacs
control
keys aren't working.

I've used alternatives to make emacs-lucid the default. I'll see
