XDG_CURRENT_DESKTOP ends up set to either GNOME if I was last using a GNOME session on my desktop before rebooting, or nothing at all. WAYFIRE_LOCAL_CONFIG remains unset by the tweaks function, so the unit that starts Wayfire starts it with a -c switch, but no config path.

Potentially DE can use wayland-session in its desktop entry for launching via a login manager/greeter.

Detect such entry seamlessly if launching it ourselves (drop argv[0] if equals self)

Entry ID is not always just a basename of desktop entry file.

Below is a diff of env variables list obtained by printenv | sort on TTY and uwsm launched graphical session

Env variables set by login manager (XDG_SESSION_ID, XDG_SEAT, etc.) and shell profile (PATH modification) is gone. Does it needed to list every variables after uwsm finalize?

OS: Arch
Login manager: lemurs (lemurs-git from AUR, coastalwhite/lemurs@09003a8)
Session manager: uwsm (uwsm from AUR, 0.14.0)
Compositor: Hyprland (Xwayland disabled custom build, 0.34.0)
Terminal: cosmic-term (Aracritty-based)

Option to launch apps as transient services, not scopes

The plan so far:
Build basic structure around argparse subparsers.
Use shell insert for environment preparation, keep this section of plugin support.
Scope of potential python code plugins is undecided as of yet, maybe hold off until a working prototype is released.
Cover #3 out of the box.

• Working prototype (py)
• Update manuals
• Decide on python-side plugins
• Desktop entry support in app subcommand (namely proper handling of various %* fields)
  • launching without arguments (drop % fields)
  • non-argument % fields support
  • argument fields support

As the issue name suggests, the script automates the copy against $BIN_PREFIX instead of using the correct $EXEC_PREFIX variable.

Whenever I run uwsm -h, I find that it floods my terminal with a lot of information. I have to fullscreen the terminal or reduce the font size in order to see all of the text.

I think it would be a good idea to move the more verbose information to manpages to make it easier to read (and reduce the cognitive load).

A couple examples on how to set this up with meson (requires #17):

• systemd uses an XML-based manpage generator: https://github.com/systemd/systemd/blob/414ae39821f0c103b076fc5f7432f827e0e79765/man/meson.build
• sway uses scdoc: https://github.com/swaywm/sway/blob/c5fd8c050f7ddbfe3e5b7abc8f5f6ace3a3c5307/meson.build#L124C21-L124C26

I was thinking about adding doctest for a few of these functions. it's part of the standard library so won't incur an extra dependency.

Some of these functions would be hard to make sense of without some examples of input, and some testing is probably necessary as right now the only way to confirm it works is to well run it. given that some of the capabilities likely require sudo that is probably an undesirable way to discover bugs

A quick fix, but where best to put it? Environment handler or finalizer... Leaning towards the former at the moment.

From Desktop Entries: Name, GenericName, DesktopNames. How to pass them and where to put.

• Decide if separate handling of attributes on cli and from entry is needed
  • Merge them to custom.conf drop-ins or split into a_desktop_entry.conf, b_custom.conf drop-ins or something like that

Add implementation of https://gitlab.freedesktop.org/terminal-wg/specifications/-/merge_requests/3

• terminal support
• cache for terminal desktop entry

The script is starting to get a bit too long for a single file. Splitting the source into multiple files would help make the code easier to understand and navigate.

The .validate() method of xdg.DesktopEntry.DesktopEntry performs (very) strict validation of XDG desktop files.

Because of this, many stock KDE applications, such as Dolphin, cannot be started, because they contain localized keys using an invalid locale identifier x-test.

$ uwsm app org.kde.dolphin.desktop
Entry /usr/share/applications/org.kde.dolphin.desktop failed validation:
  err: Invalid key: Keywords[x-test]
  err: Invalid key: Name[x-test]
  err: Invalid key: GenericName[x-test]

$ grep x-test /usr/share/applications/org.kde.dolphin.desktop
Name[x-test]=xxDolphinxx
GenericName[x-test]=xxFile Managerxx
Keywords[x-test]=xxfilesxx;xxfile managementxx;xxfile browsingxx;xxsambaxx;xxnetwork sharesxx;xxExplorerxx;xxFinderxx;

cycle through $XDG_CURRENT_DESKTOP and load matching wayland-session-env-*

I don't know what's up with uwsm, but it started doing this error on startup checks now. How do I reach graphical target if I'm starting this from a TTY?

Arch Linux, updated as of this post.

Edit: The graphical.target service appears to require a display-manager.service to operate. What display manager am I supposed to be using with uwsm?

Restore some features of shell variant, like customization of env varnames lists via environment variables. Maybe control other things via env, like desktop names for XDG_CURRENT_DESKTOP.

I have this in my hyprland config file:

$cursor-theme = capitaine-cursors
$cursor-size = 48
env = XCURSOR_SIZE,$cursor-size
env = XCURSOR_THEME,$cursor-theme
exec = hyprctl setcursor $cursor-theme $cursor-size
exec = gsettings set org.gnome.desktop.interface cursor-theme $cursor-theme
exec = gsettings set org.gnome.desktop.interface cursor-size $cursor-size
exec = uwsm finalize XCURSOR_THEME XCURSOR_SIZE

I have corectrl set up as an autostart service, which ends up using the wrong cursor. Could it be because autostart services are started before the compositor signals readiness?
I checked the environment variables like this: cat /proc/$(pidof corectrl)/environ | tr '\0' '\n'
