GNOME is planning to replace Evince with https://gitlab.gnome.org/GNOME/Incubator/papers, possibly as soon as GNOME 47.alpha. We should package the new app and provide our feedback regarding its readiness to upstream.

I did initial Papers packaging and here is the new package review request for it: https://bugzilla.redhat.com/show_bug.cgi?id=2305882

OK, the package is now finally through the review and in F41 updates-testing and in rawhide.
dnf install --enablerepo=updates-testing papersto test.Thank you Kalev!
Metadata Update from @ngompa:
@jbicha has proposed replacing Evince with Papers in Debian 13.
I believe Fedora should consider doing the same for Fedora 42 even though GNOME hasn't adopted Papers upstream yet. I've been using Papers exclusively for months and it's been great, and it's far nicer to use than Evince.

Metadata Update from @tpopela:
Thanks Tomas for proposing this discussion to the working group meeting.
Worth mentioning that CentOS Stream 10 and, consequently, RHEL10 already made the switch to Papers. See https://gitlab.com/redhat/centos-stream/release-engineering/comps/-/blob/c10s/comps-centos-stream-10.xml.in#L417
It would be great if we could align GNOME - Fedora - C10S
I also think that Papers works pretty well now. I'm for replacing Evince with Papers in Fedora too.
Now that we have Papers 48 beta, we can do this.

Metadata Update from @ngompa:
Just to restate some details from my Debian email that I haven't had time to work on yet. This needs some work done in upstream libraries to use Papers ahead of Evince for GTK's print preview.
IIRC, Niri uses this portal implementation, so it's not completely true that it's GNOME only.
There are two GTK3 forks of Evince currently maintained in Fedora: Xreader (from XApps/Cinnamon) and Atril (from MATE). Wouldn't either of these work fine for GTK3?
I didn't test it, but I don't believe you need to use a GTK3 app for the GTK3 Print Preview feature because it's just a link to a separate app really. So I think that GTK3 ought to use Papers for that feature if installed and then fall back. Actually, this probably means that things weren't working for MATE anyway unless MATE was shipping the evince previewer. If the previewer is not available, GTK just hides the Print Preview button so people may not have been aware that something was missing.
For reference, I believe this is the working command to replace in GTK:
papers-previewer --unlink-tempfile --print-settings %s %fHmm, then it should be an easy fix.
Actually I did test it with the gtk-3.0 settings.ini so yes, it works fine to have Papers provide the GTK3 previewer. I just don't think settings.ini is useful for supporting multiple desktops so I think a code fix instead of a .ini fix is needed.
We also need to change the mimeapps.list in the gnome-desktop3 package.
Metadata Update from @mclasen:
This change is tentatively approved for F43. We will implement in rawhide now. We can create a new issue report if we wish to reconsider before release, which might make sense if Papers does not progress through the upstream incubation process as expected.
Metadata Update from @catanzaro:
I hope that I can finish the content area accessibility work at least for the 49 release, so we don't have an a11y regression because of this change.
Hi, we actually discussed this yesterday and noted that Evince is switching to GTK 4, so we expect accessibility in Evince to break, putting it on par with Papers.
This is now done in Rawhide comps. Now we need to patch things to complete the transition.
This change is implemented in rawhide.
Reminder about the consequences here:
Additionally, sushi is probably broken now.
https://pagure.io/pungi-fedora/pull-request/1482 to do this in Silverblue.
I would like to do that otherwise we have to maintain test code for both Evince and Papers in openQA to make the tests pass on both Workstation and Silverblue.
I think Sushi won't be broken because I believe it only uses evince-libs not evince.
