steamFrame.launchers.<desktop ID> takes the app's own entry (a Flatpak's
export, a Nix package's or a host file) and rewrites only its command lines
(hostEnv, env, flatpakArgs, args, wrappers) and the keys asked for
(mimeTypes, defaultFor, settings), so name, icon, translations and actions
stay the app's and follow its updates.
- Package entries are rewritten at build time; Flatpak/host file entries at
runtime by steam-frame-nix-launchers into
<session.runtimeDir>/steam-frame-nix/applications (tmpfs), on switch, at
login and when Flatpak installs/updates apps (path unit); the Home Manager
links point there.
- keyring.{enable,electron} replaces steamFrame.keyring.{flatpaks,programs}
(clean break: the old options fail with the new form).
- Firefox's launcher is the Flatpak's entry with the profile wrapper in
front (no --profile for the profile manager); Jellyfin's hardware
decoding sets flatpakArgs and env.
- cleanup --all removes the tmpfs entries.
- Check on copies of the real Element, KRDC, Firefox, gedit, Jellyfin and
Claude entries, quoting and generator behaviour.

# The Firefox Flatpak wrapper (firefox.nix, a steamFrame.launchers wrapper):
|
|
# gets the entry's full command line (`flatpak run … org.mozilla.firefox …`)
|
|
# as its arguments. Outside the nested desktop it just runs it. In the nested
|
|
# desktop (KDE) it adds `--profile <desktop profile>` (not to the profile
|
|
# manager action, --ProfileManager); with the fullscreen fix it links that
|
|
# profile's user.js to the sandbox path desktopJs (undoing the fix there)
|
|
# right before Firefox starts, and once Firefox has exited and the profile is
|
|
# no longer in use (a second launch that only hands its URL to the running
|
|
# Firefox returns at once) removes the link and the value Firefox stored from
|
|
# it in prefs.js. A user.js of the user's own is never touched. After a crash
|
|
# the next launch or steam-frame-nix-cleanup finishes the removal.
