What this adds for players

RecompLauncher can now install SpartanPort from its releases and set it up for the player.

• Easy Setup: the player picks their own God of War III Remastered dump folder (the one with eboot.bin), the launcher checks it and passes it on, and Play starts the game with --play.
• Checked during setup: the launcher runs the game's image preparation on the chosen folder, with a progress bar, so a bad or unsupported dump is reported on the setup screen instead of when pressing Play.
• Settings in the launcher: window mode, resolution, engine frame rate, frame rate limit, V-Sync, upscaling and its quality, anti-aliasing, texture filtering and Show FPS appear on the game's page and in Big Picture mode. They edit spartanport.ini, and only the keys they list.
• Update folder: if the player keeps the 01.02 update apart from the game, the launcher asks for it (optional) and the port uses it.
• More settings: volume, vibration and right stick sensitivity sliders, and frames queued and background shader compiling under Show Advanced Options.
• Saves: the launcher knows where user/savedata is for backups and cloud saves, and has buttons for the saves/log folder and the shader cache.

Files and packaging (commits 1 and 3)

• New recomplauncher.json at the repo root, checked against the published schema.
• packaging/windows/package.sh copies it to the top of spartanport-windows.zip, next to SpartanPort.exe.
• packaging/linux/build.sh installs it at /recomplauncher.json inside the AppImage.

Code changes (commits 2 and 4)

SpartanPort --prepare --game <folder>: runs the existing image preparation (prepare_image) and content profile on that folder, prints progress <0..1> <text> lines, and exits 0, or 1 with the reason. It stops before the probe, so no window opens and the game doesn't start.

• Only applies when the launcher passes --prepare. Without it, every start, --run and --play behave exactly as before.
• Reuses the runner's existing functions; no installer or check code is rewritten. About 45 lines in runner/mod.rs, plus the route in startup.rs and main.rs.
• Tests: the --prepare route, a successful run on the synthetic game (progress lines and output files, nothing started), and the two failures (no eboot.bin, missing --game). cargo test --test startup --test runner and cargo clippy --all-targets pass.

SpartanPort --play --update-dir <folder>: uses that folder as the game update for that start, only when it holds an eboot.bin (a skipped pick has none). It is not saved to settings.json, and a normal --play is unchanged. About 10 lines in startup.rs and main.rs, with a test.

Nothing else changes: no gameplay, graphics, saves or config format changes, and no game files are added.

Not included

No dumps list: Redump covers discs, and I found no verified size and CRC32 for these PS4 folder dumps in the project's docs (only the eboot.bin SHA-256 in docs/PATCHES.md, which isn't the same thing). Easy to add if there's a source.

Summary by CodeRabbit

• New Features
  • Added a preparation option for a selected game folder, with progress updates and checks for required game files.
  • Added launcher settings for graphics, audio, controls, and advanced options, along with shortcuts for saves, logs, and shader-cache management.
  • Linux and Windows packages now include the launcher configuration.
  • Added support for selecting a game update folder when launching, when it contains the required game file.

Walkthrough

The change adds a RecompLauncher definition to Linux and Windows packages. It adds a --prepare route that prepares game files and handles a valid --update-dir argument.

Changes: RecompLauncher Setup and Preparation

Layer / File(s)	Summary
Define and package the launcher configuration recomplauncher.json, packaging/linux/build.sh, packaging/windows/package.sh	The JSON defines SpartanPort launch arguments, paths, graphics and performance options, and actions. Both packaging scripts copy the JSON into their staged packages.
Route and execute preparation launcher-rust/src/startup.rs, launcher-rust/src/main.rs, launcher-rust/src/runner/mod.rs, launcher-rust/tests/startup.rs, launcher-rust/tests/runner.rs	The launcher recognizes --prepare as its first argument and runs preparation after validating the arguments and game folder. Tests cover successful preparation, progress output, generated files, and errors.
Apply update-directory arguments launcher-rust/src/startup.rs, launcher-rust/src/main.rs, launcher-rust/tests/startup.rs	The launcher uses the folder after --update-dir when it contains eboot.bin. Tests cover missing values and invalid folders.

Merge Risk: Low · up to 5a5c5

Relative paths can fail for AppImage preparation or update selection. Custom INI overrides can also make launcher settings ineffective. Absolute paths and default configuration provide workarounds.

Review details

Systems and components

• observed — launcher-rust (service) was modified; 5 changed files map to changed impact.
• observed — packaging (service) was modified; 2 changed files map to changed impact.
• observed — recomplauncher.json (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in packaging/linux/build.sh: The build script now copies the root recomplauncher.json into the AppDir; a comment identifies it as input for RecompLauncher setup and game startup.
• observed — Modified behavior in packaging/windows/package.sh: Documents the role of recomplauncher.json and copies it into the staged Windows package root.
• observed — Modified behavior in launcher-rust/src/main.rs: Route::Prepare now passes its arguments and shared context to runner::prepare, then exits with the returned code.
• observed — Modified behavior in launcher-rust/src/main.rs: Route::Play now loads mutable settings and, when startup::update_dir_arg(&args) returns a directory, overwrites update_dir with its lossy string representation.

Full details: Title check

Explanation

The title "Feat(Launcher): added recomplauncher.json for RecompLauncher" matches the main change. The PR adds a root-level recomplauncher.json configuration file for RecompLauncher, copies it into the Windows and Linux packages, and adds a --prepare route to the Rust launcher. The title covers the configuration file but not the --prepare command or the --update-dir option, which are also substantial parts of the change. That gap is acceptable because a title does not need to cover every detail. The title is specific and uses a conventional commit style.

Full details: Docstring Coverage

Explanation

Docstring coverage is 66.67% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 6 functions across 7 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

resolving these paths from user_dir; if it does not, identify and use its

Resolve the prepare game path against the invocation directory

When an AppImage user passes a relative --game folder, AppRun has already changed the working directory. prepare_only can therefore report No eboot.bin and exit before setup. Resolve relative game paths against OWD for AppImage launches, while preserving absolute paths and non-AppImage behavior.
