-- Autostart
--
-- `exec-once` no longer exists in 0.56; startup is an event handler.
--
-- Session: Fedora installs two sessions, "Hyprland" and "Hyprland
-- (uwsm-managed)". Panama targets the uwsm one, because
-- xdg-desktop-portal-hyprland's systemd unit requires graphical-session.target
-- and Fedora ships no hyprland-session.target -- without uwsm, screen sharing
-- in OBS/Sunshine/Zoom silently fails. The target is started explicitly below
-- so the plain session works too.
--
-- Anything that ships a systemd user unit is started as a unit rather than as
-- a compositor child. That is not cosmetic: under uwsm, units get the correct
-- activation environment (see uwsm/env), they restart on failure, and they
-- shut down in order. Panama's `change-settings` script enables them once;
-- the explicit starts here make a fresh clone work before that has run.

hl.on("hyprland.start", function()
    -- Publish the session environment to systemd and D-Bus so user units and
    -- the portals can see WAYLAND_DISPLAY. Cheap, and essential without uwsm.
    hl.exec_cmd("dbus-update-activation-environment --systemd WAYLAND_DISPLAY XDG_CURRENT_DESKTOP=Hyprland")
    hl.exec_cmd("systemctl --user start hyprland-session.target")

    -- Units: polkit prompts, wallpaper, launcher daemon, idle/lock. All four
    -- carry `ConditionEnvironment=WAYLAND_DISPLAY`, and hl.exec_cmd fires
    -- commands without waiting for them to finish, so the dbus-update call
    -- above racing this one is not safe to assume complete -- a lost race
    -- leaves the Condition unmet and the unit silently never starts (exit 0,
    -- no error). hypridle is the only listener for the logind Lock signal,
    -- so that failure mode is "lock-session goes to nobody". Re-import
    -- synchronously in the same shell invocation first so the Condition
    -- always sees it, regardless of how the dbus-update call above scheduled.
    -- panama-polkit-agent replaces hyprpolkitagent, whose prompt is compiled
    -- into its binary and cannot be themed. Only one agent may register per
    -- session, so they must not both start. hyprpolkitagent stays INSTALLED as
    -- the fallback: `systemctl --user start hyprpolkitagent` restores the stock
    -- prompt if Panama's ever fails to come up.
    hl.exec_cmd("systemctl --user import-environment WAYLAND_DISPLAY XDG_CURRENT_DESKTOP && systemctl --user start panama-polkit-agent.service hyprpaper.service vicinae.service hypridle.service")

    -- Pending repairs for this machine, if any. Oneshot: it checks, tells the
    -- user when there is something to tell, and exits. Started here rather
    -- than enabled so it belongs to the Hyprland session; see the unit.
    hl.exec_cmd("systemctl --user start panama-migrate-notify.service")

    -- Notices when a program dumps core and says so once per session. Under
    -- GNOME, ABRT does this; here nothing did, and applications died silently.
    hl.exec_cmd("systemctl --user start panama-crash-watch.service")

    -- Text expansion. change-settings runs `espanso service register`, which
    -- writes and enables espanso's own user unit; the explicit start makes the
    -- first Hyprland login after a fresh install work rather than the second.
    -- Started on its own line: unlike the units above it carries no
    -- ConditionEnvironment, and a missing unit (espanso not yet registered)
    -- must not muddy the start of the four that lock and wallpaper depend on.
    hl.exec_cmd("systemctl --user start espanso.service")

    -- The shell: bar, dock, overview, quick settings, notifications, capture.
    -- A supervised unit rather than a compositor child, for the one property
    -- a child cannot have: if the shell crashes, systemd restarts it in two
    -- seconds instead of leaving a desktop with no bar until someone knows
    -- what to type. The unit ships in config/local/share/systemd/user and is
    -- started per-session here like every other Panama unit.
    hl.exec_cmd("systemctl --user start panama-quickshell.service")

    -- Removable-media automounting. GNOME did this invisibly via gvfs+udisks;
    -- outside GNOME something has to ask udisks to mount. No tray icon: the
    -- Quickshell bar already has a tray, and udiskie's own icon would be
    -- redundant. -f opens Nautilus when you click the mount notification.
    hl.exec_cmd("udiskie --automount --notify --no-tray --file-manager nautilus")

    -- Keyring unlock, for Nextcloud and Bitwarden credential storage.
    hl.exec_cmd("/usr/bin/gnome-keyring-daemon --start --components=secrets,ssh,pkcs11")

    -- Nextcloud and Bitwarden are NOT started here. Both ship a
    -- ~/.config/autostart/*.desktop entry, and systemd's own
    -- systemd-xdg-autostart-generator turns every such entry into a
    -- `PartOf=graphical-session.target` unit (`[email protected]`,
    -- `[email protected]`) that fires once the uwsm
    -- session brings up graphical-session.target -- confirmed live via
    -- `systemctl --user list-units 'app-*@autostart.service'`. An explicit
    -- second launch here used to duplicate that: for Bitwarden specifically,
    -- each `flatpak run` gets its own sandbox instance, so the two starts
    -- didn't just race, they left two competing processes fighting over the
    -- app's single-instance lock, with neither reliably owning a usable
    -- window. Trust the generator instead of re-launching.
    --
    -- RustDesk is deliberately absent too: it ships an enabled *system*
    -- service (`rustdesk --service`) that spawns --server and --tray for the
    -- session on its own. Starting it here as well would give you two trays.
end)

-- Tear down what the start handler brought up.
--
-- This stopped `hyprland-session.target`, which does not exist on Fedora --
-- systemctl reports "Unit not found" and the handler achieves nothing. The
-- units started above are not children of the compositor, so nothing else
-- stopped them either: hyprpaper, hypridle, vicinae and the polkit agent kept
-- running after logout, and each one Requires=graphical-session.target, so
-- that target stayed active with no session behind it.
--
-- The next login then failed. Both uwsm and gnome-session refuse to start into
-- a session that is already running ("A compositor or graphical-session*
-- target is already active!"), so "Hyprland (uwsm-managed)" and GNOME both
-- bounced straight back to the login screen while plain Hyprland -- which
-- makes no such check -- kept working. The desktop appeared to be the only one
-- that functioned, when it was the one leaving the mess.
--
-- Stopping graphical-session.target is enough on its own: every unit above is
-- PartOf= it, so they come down with it, and it carries StopWhenUnneeded=yes.
-- It is stopped rather than the units listed individually so that a unit added
-- to the start handler later cannot be forgotten here.
