Description Toby Haynes 2023-08-22 15:46:37 UTC

Current builds of Emacs 29.1 do not respect the HiDPI settings, resulting in the window being unreadable when used across monitors with substantially different resolutions. 

Emacs 29.1 also brings support for Tree Sitter modes, which provide improved support for many languages in syntactic colouring, navigation, indentation and other areas.

Emacs pre-test has builds demonstrating both these features:

https://copr.fedorainfracloud.org/coprs/bhavin192/emacs-pretest/

It would be useful to see Fedora 39 onward support both these improvements.

Reproducible: Always

Steps to Reproduce:
1.Install regular Fedora Emacs
2.Switch to a monitor with a different HiDPI scaling
3.Observe no scaling is applied
4.Observe that no tree-sitter functions are available (M-x c-ts-mode RET fails)


Expected Results:  
HiDPI and Tree Sitter functionality are available.

As an every day Emacs user, I'm very interested by this.

Is there anything I can do to help ?

You could run the preview build at https://copr.fedorainfracloud.org/coprs/bhavin192/emacs-pretest/ and report any problems you encounter there.

For bohdi - would it be possible to add a subpackage for --with-pgtk build as well?

The copr emacs-pretest is working for me.

I think that's too big a change to surprise people with this close to the Fedora 39 freeze, so let's target that for Fedora 40.  https://src.fedoraproject.org/rpms/emacs/pull-request/33

An additional -pgtk package wouldn't affect anyone not choosing to install it.
