FrameDrop sideloads a Linux zip as a Steam Devkit Game. Frametop can't be copied over as an app, so the zip holds a small installer: playing it runs get.sh --yes in a transient user service (Steam reaps the title's process tree on quit) and shows progress in a GTK window. - probe/probe.sh records what a Devkit Game can reach. On SteamOS 0.3.0 it runs on the host with git, podman, systemd and GTK, even with the SLR4 compat tool set; inside SLR4, flatpak-spawn --host reaches the host. - devkit.sh registers a folder the way FrameDrop does (Valve's devkit-utils), for testing without a PC. - build.sh makes a reproducible Frametop.zip and the FrameDrop manifest. Nothing is published. Open: whether FrameDrop keeps the exec bit, and its start command and runtime choice. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# Frametop's FrameDrop installer: the start command of the "Frametop" title that FrameDrop
|
|
# puts in the Steam library. Playing it installs Frametop (or updates it) with the one-line
|
|
# installer, get.sh --yes, and shows its progress in a window.
|
|
#
|
|
# Steam ends a title's whole process tree when it's quit, and starts it with a high OOM score,
|
|
# so the install runs in a user service of its own (frametop-framedrop-install) and the window
|
|
# only follows its log. Quitting or closing the window leaves the install running; playing the
|
|
# title again reattaches to it.
|
|
#
|
|
# Usage: frametop-install.sh [--dry-run]
|
|
# --dry-run clone into ~/.cache/frametop-framedrop/dry-run instead of ~/frametop, and
|
|
# don't run install.sh (get.sh --clone-only), for testing this flow
