sway: Switch to 1.0

[primeos]

First commit (moves sway-beta to sway)

This is the result of executing:
git mv -f pkgs/applications/window-managers/sway/beta.nix pkgs/applications/window-managers/sway/default.nix
git mv -f nixos/modules/programs/sway-beta.nix nixos/modules/programs/sway.nix

And removing sway-beta from the following files:
pkgs/top-level/all-packages.nix
nixos/modules/module-list.nix

Second commit (manual changes)

Should be a separate commit to keep the history readable.

TODOs

• Compare modules. Do we need a release-notes entry? -> There are a few breaking changes but Sway is probably not relevant enough and most users probably already use 1.0 or can easily update their configuration.
  • sway-beta introduced a package option.
  • The new module does not need any capabilities anymore and drops the sway group.
  • The keymap may now be specified withing Sway's configuration file (TODO: Does XKB_DEFAULT_* still work?)
  • WLC_REPEAT_* will most likely not work anymore.
  • We've removed i3status by default, this can break setups (should we re-add it?).
  • swaylock and swayidle are now separate packages.
  • From the upstream release notes:
    • We have completely overhauled the codebase. Some behaviors were changed to match i3 behavior, in breaking ways. There are likely many bugs we don't know about. Your millage may vary.
    • swaygrab has been removed. For screenshots, try grim, and for video capture try wlstream
    • Experimental Nvidia support has been deprecated since its inception, and has now been removed entirely. Please use nouveau and consider future purchases from GPU vendors that support open source. Other proprietary drivers are also unsupported.
    • swaylock is now distributed separately
    • swayidle, a new idle management daemon, is available separately
• Backport to 19.03.
• Test different setups / collect feedback - are our current defaults ok?
• Wait for an official patch to fix the build. -> Official patch is now applied.
• Verify that security.d/00-defaults works correctly and review sway-security. -> security.d is irrelevant ATM (source) and the sway-security man page is not in 1.0. (config.d is also empty.)

Things done

• Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS)
• Built on platform(s)
  • NixOS
  • macOS
  • other Linux distributions
• Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
• Tested compilation of all pkgs that depend on this change using nix-shell -p nox --run "nox-review wip"
• Tested execution of all binary files (usually in ./result/bin/)
• Determined the impact on package closure size (by running nix path-info -S before and after)
• Assured whether relevant documentation is up to date
• Fits CONTRIBUTING.md.

Cool! Thank you!

[primeos]

A few things could still be improved/discussed but this should be ready now.

Please resolve the merge conflict.

[primeos]

Just wanted to avoid rebasing for now (that did not cause any conflicts because the relevant commit was already in my branch, automatic merging probably failed because the commit was cherry-picked and it couldn't find the correct common ancestor) because it makes reviewing the changes through GitHub harder (IMO). But it's ready to be merged via GitHub now and I've also squashed some commits (keeping two separate commits makes sense IMO to keep the history readable). The only final change was to drop the package option for now (I did not test this change yet but I can do this tomorrow if no one beats me to it).

Update: I tested the changes again to be sure everything still works.

Why is this done? The files are installed in the store path, right?

[primeos]

That's because most users (including me) will probably choose the default workflow from the wiki (https://github.com/swaywm/sway/wiki#configuration) which I also referred to in the documentation of the enable option:

The suggested location for the sway configuration file is ~/.config/sway/config. To begin configuring sway, create this directory and copy the default config.

mkdir -p ~/.config/sway
cp /etc/sway/config ~/.config/sway/
$EDITOR ~/.config/sway/config

Read the default config - it has comments that explain what each option does. Read man 5 sway for more information about each config command.

But then their copy won't get updated and the /nix/store/ paths will eventually getting garbage collected. And I also stopped installing the default wallpapers into /nix/store/ but we could revert that.

~/.config/sway/backgrounds/Sway_Wallpaper_Blue_1920x1080.png is not optimal but I kept it as an example.

An alternative would be to install the default wallpapers e.g. into /run/current-system/sw/share/sway/wallpapers if we want to keep them.
Edit: Or e.g. /run/current-system/sw/share/backgrounds/sway which would be the default location.

I decided to merge it so that we have enough time to test it with different setups and get some feeback (I'm currently testing the backport for 19.03 and will hopefully be able to merge it soon).

I've opened #57602 for further discussion, feedback, etc.
