The icon fallbacks were links an activation script made (and tracked in
~/.local/state/steam-frame-nix/icon-fallbacks) after scanning the desktop
entries. They are Home Manager links now:
~/.local/share/icons/hicolor/scalable/apps/<name>.svg -> the largest Breeze
app SVG, for utilities-terminal and preferences-system (SteamOS' Konsole and
KDE System Settings) plus iconFallbacks.extra; a name Breeze doesn't have
fails the build. enable = false: none.
- The scan is read-only now (steam-frame-icon-fallbacks --suggest): each
switch prints icons Steam can't find that Breeze has (for extra) and
fallbacks hicolor has anyway.
- hicolor's mtime is bumped when the set of links changed between
generations, so a running Steam rescans (GTK checks theme dir mtimes).
- The script's old links at those paths are removed before
checkLinkTargets (they would be collisions); any others and the manifest
go through steam-frame-nix-cleanup.
The assertion for the old list form stays until ~2026-12.
Every module imports cleanup.nix (also exported as
homeManagerModules.cleanup), which
- puts steam-frame-nix-cleanup (install.sh cleanup) on PATH;
- runs `cleanup --orphans --quiet` after linkGeneration on every switch,
keeping what the configuration still uses (steamFrame.cleanup.keep, set
by the modules: debugger while steamvrDebugger is on, the Firefox desktop
profile's user.js while its fix applies); in a dry run it runs with
--dry-run;
- runs `cleanup --all` instead when Home Manager's `uninstall = true;` is
set (the manual uninstall route);
- removes links of older versions at paths Home Manager is about to own
before checkLinkTargets (steamFrame.cleanup.migrateLinks), which would
count as collisions otherwise.
install.sh cleanup gains --quiet (only actions, deferrals and warnings;
the header only when something is printed). The Jellyfin module's own
removal of the old shim copy goes: cleanup does it.
- pinned-desktop (VERSION 3): drop the stop() of a predecessor global that
never existed in this repo; log errors as "sfui <NAME>:" through one
guard helper, like the grid patch.
- steamCloseButton.enable is a mkEnableOption like the other feature
switches; enable descriptions no longer end in a stray newline.
- launcher-menu.nix header lists show-all and no longer claims the patches
use no webpack module; hiddenApps mentions showAllApps.
- Patch comments: frame-controls ring timing matches the code (half of
longPressMs, at most 1 s), window-curvature names frame-controls as what
moves its control into the bar, steam-close-button no longer refers to an
unpublished version.
Without Steam's Developer Mode the "+" menu hides konsole, systemsettings,
dolphin, plasma-discover, vlc and a few more by executable name. The patch
empties only that list's iterator, leaving the setting itself untouched.
launcherMenu.grid = { enable; columns; maxRows; } restyles the "+" menu's
programs section as a grid of tiles (icon, name below): Steam's own items
stay in place, maxRows limits the visible rows, and Steam's scroll fade is
recomputed so it only shows where there is more to scroll. The pinned
Desktop row is slim and centred in tile mode.
launcherMenu.iconFallbacks (default utilities-terminal, preferences-system)
installs hicolor copies of Breeze app icons, since Steam resolves program
icons only in hicolor; Konsole and KDE System Settings had none.
The checker gains checkOnly "stylesheet" signatures (matched against the
bundle's CSS files) to cover the scroll fade's gradient; launcher-menu-grid
signatures cover the section keys and the ScrollFade classes.
Runtime patches no longer use webpack module ids or minified export
names, which change with every Steam UI build:
- modules/lib/finders.js: finder library (getWebpackRequire,
findModule/findExport by source text and shape, resolveAll with a
per-page cache, findFiberUp/findFiberDown/findInReactTree), installed
once per page as window.__sfuiFind.
- modules/lib/signatures.json: the signatures, per patch, shared by the
patches and the checker. lib/default.nix mkPatch wraps a patch
`(find, sigs, opts) => ...` with the library, its signatures and
options; exposed as steamFrame.uiPatches.lib.
- Keyboard patch (VERSION 10): layouts module, current/enabled layout
getters, arrow keys, VR keyboard status and VirtualKeyboardManager are
found by signature; if one doesn't match it reports which and leaves
Steam untouched. unpatch.js uses references the patch remembered.
The helper logs inject results when they change.
- launcher-menu launch/pinned-desktop use the library's fiber helpers;
launch no longer depends on the bar popup's window name.
- scripts/check-signatures.mjs (+ webpack-modules.mjs): extracts module
factories from the installed bundles without a browser and checks
every signature (found / ambiguous / missing, with module ids and
export names). README: "Finders and signatures", "After a Steam update".
Stock, clicking a program in the VR dashboard's "+" menu only calls
SteamClient.Apps.LaunchNonSteamApp; the menu stays open until the
program's window appears, so users click again and launch it twice.
New launch/ patch (SharedJSContext) wraps LaunchNonSteamApp, whose only
caller is this menu: closeOnLaunch closes the menu through the "+" bar
button's own popup handle right after a launch; launchDebounce ignores
repeated launches of the same command line within N seconds (logged to
the steam-ui-patches journal). Both opt-in, like the other launcherMenu
options.
steamFrame.uiPatches.patches registers JS patches that the
steam-ui-patches user service keeps injected into Steam's (or SteamVR's)
web UI over the local CEF DevTools ports and reverts when it stops.
steamFrame.launcherMenu uses it for the VR "+" menu: sort = true sorts
the programs by name; pinDesktop = "top" / "bottom" pins Desktop above or
below the scrolling list.
