Description

A batch of library/launch quality-of-life changes plus the removal of all effectual (Effect-typed) APIs from the ogi-addon public surface.

  • Remove Game now deletes files: removing a game from the library also deletes its install directory (cwd). Deletion failures surface as a warning instead of failing the removal.
  • Redistributable failures are non-fatal: a failed redistributable no longer fails the whole setup — per-item warnings still show, and the Steam shortcut is added either way (Linux UMU flow) or the game is kept in the library (Windows flow).
  • Show in Folder: new button in the per-game configuration modal, opening the game's install directory via the existing fs:show-file-loc IPC.
  • Launch despite addon failure: when pre-launch addon hooks fail, PlayPage and the GameLaunchOverlay (wrapper launches) now prompt with Launch Anyway / Cancel instead of hard-failing.
  • Game-specific launch context: addons receive a second argument on their connect listener: { gameSpecificLaunch: boolean }. OGI threads an OGI_GAME_LAUNCH=1 env var from --game-id detection through the executor spawn so addons can selectively start components.
  • ogi-addon API cleanup: all *Effect publics on OGIAddon, Task, and EventResponse are private or removed; extraction is exported as a promise; EventResponse.defer takes plain thunks and nextDeferred() replaces the Effect-based deferred accessors. Effects remain internal implementation detail only — verified via generated d.ts.

Example

// addon side
ogi.on('connect', (_event, context) => {
  if (!context?.gameSpecificLaunch) startHeavyComponents();
});

Next Steps

  • Manual pass: remove a game, force a redistributable failure, and launch with a broken addon hook
  • Consider deleting the per-game UMU wine prefix on remove as well
  • Hide Task's constructor overloads that reference the unexported OGIAddonWSListener type
  • Bump package versions for @ogi-sdk/connect / @ogi-sdk/executor / ogi-addon

Summary by CodeRabbit

  • New Features

    • Added “Show in Folder” for configured game directories.
    • Added confirmation before removing games.
    • Added “Launch Anyway” or “Cancel” options when an addon fails before launch.
    • Game-specific launches now provide improved addon context.
    • Added retry handling for failed redistributable installations.
  • Bug Fixes

    • Prevented deletion of protected, shared, or active game directories.
    • Removal now reports whether files were deleted.
    • Partial redistributable failures no longer block setup.
    • Improved archive extraction errors and prompt cancellation.
  • Improvements

    • Simplified addon event handling and extraction behavior with Promise-based APIs.

📝 Walkthrough

Walkthrough

The change updates filesystem cleanup and redistributable handling, passes game-specific launch context to addons, adds interactive addon failure prompts, and migrates addon deferred work and extraction APIs from Effect-based interfaces to Promise-based interfaces.

Changes

Reliability and launch flow

Layer / File(s) Summary
Filesystem and library operation handling
application/src/electron/handlers/handler.fs.ts, application/src/electron/handlers/handler.library.ts, application/src/electron/lib/delete-guards.ts, application/src/electron/lib/delete-guards.test.ts, application/src/frontend/components/GameConfiguration.svelte, application/src/lib/electron-rpc.ts, application/src/electron/tsconfig.json
Archive extraction failures enter the filesystem error boundary. Protected, running, and shared game directories are not recursively deleted. Removal responses report file deletion status.
Redistributable installation outcomes
application/src/electron/handlers/handler.umu.ts, application/src/electron/handlers/handler.redists.ts, application/src/electron/handlers/handler.library.ts, application/src/frontend/lib/setup/setup.ts, application/src/frontend/views/DownloadView.svelte, application/src/lib/electron-rpc.ts
Redistributable results support partial completion and warnings. Setup preserves completed entries and provides retry handling.
Game-specific addon launch context
application/src/electron/lib/single-instance-launch.ts, application/src/electron/manager/manager.addon.ts, packages/connection/lib/protocol.ts, packages/executor/lib/addon.ts
The launcher detects game-specific arguments. Addon processes receive OGI_GAME_LAUNCH=1, and addon connections receive gameSpecificLaunch.
Addon failure launch decisions
application/src/frontend/lib/core/launch-prompt.svelte.ts, application/src/frontend/components/GameLaunchOverlay.svelte, application/src/frontend/components/PlayPage.svelte, application/src/frontend/components/built/AddonFailurePromptModal.svelte
Pre-launch addon failures show error details with Launch Anyway and Cancel actions. Continuing restores launch state and logs a warning. Canceling stops the launch.
Promise-based addon runtime APIs
packages/ogi-addon/src/EventResponse.ts, packages/ogi-addon/src/EventResponse.test.ts, packages/ogi-addon/src/extraction.ts, packages/ogi-addon/src/main.ts
Deferred work, input handling, extraction, and WebSocket scheduling use Promise-based APIs. Effect helper methods become private or internal.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to dcf7b

The PR now deletes game install directories during removal and changes launch and addon lifecycle handling. Current behavior can misidentify running games, leave stale launch state, allow recursive deletion to reach unintended or protected paths, and execute deferred addon work after completion, creating a material risk of data loss or incorrect launches. Merge should be blocked until these safeguards are fixed or explicitly accepted.

Poem

A rabbit guides each Promise task,
Then waits for answers when they ask.
“Launch anyway, or cancel here?”
Safe paths guard the files we hold dear.
The addon flow now runs clear.

Greptile Summary

The PR improves library removal, launch failure recovery, redistributable retries, and the promise-only add-on SDK. It also adds deletion guards and per-game operation queues, but previously reported deletion ownership and wrapper-launch race failures remain outstanding.

  • Removes library entries while attempting guarded deletion of their install directories.
  • Makes redistributable failures non-fatal and exposes retry state in the downloads view.
  • Adds launch-anyway prompts for failed add-on pre-launch hooks.
  • Adds game-specific add-on connection context and removes Effect-typed public SDK APIs.

Confidence Score: 3/5

The PR is not yet safe to merge because game removal can still delete non-owned files and can race a Steam wrapper launch.

The deletion guards do not establish ownership of the persisted working directory before recursively removing it, and wrapper launches mutate running state outside the per-game queue used by removal.

Files Needing Attention: application/src/electron/handlers/handler.library.ts, application/src/electron/lib/delete-guards.ts

Important Files Changed

Filename Overview
application/src/electron/handlers/handler.library.ts Adds guarded recursive removal and launch serialization, but arbitrary non-owned directories remain deletable and wrapper launches still bypass serialization.
application/src/electron/lib/delete-guards.ts Protects system, application metadata, and overlapping game paths, but does not prove that a deletion target is game-owned.
application/src/electron/manager/manager.addon.ts Defines connect context as session-scoped and explicitly leaves forwarded launches to the separate per-launch hook.
packages/executor/lib/addon.ts Propagates the session-level game-launch flag to add-on processes while stripping inherited values.
application/src/frontend/lib/setup/setup.ts Treats redistributable failures as retryable terminal setup states without removing the installed game.
packages/ogi-addon/src/main.ts Converts the public add-on SDK toward promise-only APIs and emits the new connect context.

Reject relative appInfo.cwd values before recursive deletion.

cwd is persisted without runtime validation. A value such as ../Documents is resolved relative to the Electron process working directory, then passed to fs.existsSync and fsp.rm. If the directory exists, the handler recursively deletes it. Treat non-absolute paths as protected or invalid before deletion.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Only block removal for active launch states.

gamesLaunched can contain 'launching', 'launched', or 'error'. The truthiness check rejects removal when the state is 'error', even though that state is not a running game. Check only 'launching' and 'launched'.

Proposed fix
-  if ($gamesLaunched[gameInfo.appID]) {

+  if (launchState === 'launching' || launchState === 'launched') {

Use the shared active-download predicate before deleting files.

application/src/frontend/components/StorePage.svelte treats every status other than 'error' as active. This guard permits 'completed', 'seeding', and 'setup-complete' entries, so it can remove a game while currentDownloads still reports an active record. Align this predicate with the shared contract.

Proposed fix
   const activeDownload = $currentDownloads.find(
     (download) =>
-      download.appID === gameInfo.appID &&
-      !['error', 'completed', 'seeding', 'setup-complete'].includes(

Node.js process.env Windows environment variable names case insensitive destructuring rest object key casing

💡 Result:

In Node.js on Windows, the process.env object is case-insensitive for environment variable access, reflecting the underlying behavior of the Windows operating system [1][2][3]. This means that process.env.VAR and process.env.var refer to the same value [2][4][3]. Regarding your query on destructuring and rest object keys: when you destructure process.env, the keys in the resulting rest object will retain the casing exactly as they were originally defined or last set in the environment [1][3]. While access to process.env remains case-insensitive, the keys existing within the object are not normalized to a single casing (e.g., all lowercase or all uppercase) [1]. Important caveats include: 1. Worker Threads Exception: On Windows, copies of process.env within Worker threads operate in a case-sensitive manner, unlike the main thread [3][5]. This is a documented limitation where the case-insensitivity of the main process.env is not automatically preserved in the worker's environment copy [4][3]. 2. Destructuring Behavior: Because process.env is a standard JavaScript object, destructuring it (e.g., const { FOO,...rest } = process.env) will capture keys based on how they appear in the object at that moment. If you are relying on case-insensitivity to retrieve variables, ensure you reference them by the expected name, but be aware that the rest object will contain the keys as they were stored [1]. To maintain cross-platform compatibility and avoid issues with case sensitivity, it is recommended to consistently use the casing expected by your application or to normalize environment variable keys to a specific case (usually uppercase) before processing them in your code [2].

site:nodejs.org/api/process.html process.env Windows case-insensitive environment variable names main thread

💡 Result:

In Node.js, process.env on Windows handles environment variables in a case-insensitive manner when running in the main thread [1]. This aligns with the underlying behavior of Windows environment variables [1]. However, this behavior differs in Worker threads. When a Worker thread is created, it receives a copy of process.env that operates in a case-sensitive manner, unlike the main thread [1]. Additionally, it is important to note that only the main thread can perform modifications to process.env that are visible to the operating system or native add-ons [1].

Citations:


Filter OGI_GAME_LAUNCH case-insensitively.

On Windows, a lowercase inherited key can survive the destructuring and enable the addon when gameSpecificLaunch is false. Filter Object.entries(process.env) with key.toUpperCase() !== 'OGI_GAME_LAUNCH'.

Clear UMU tracking when launchWithUmu rejects.

If setup or process creation rejects, Effect.tryPromise fails before the !result.success cleanup runs. The stale app ID prevents removeApp from deleting the game files until restart. Add cleanup to the Effect failure path.

Ignore deferred work after event settlement.

When resolve(), complete(), or fail() sets resolved, defer() still queues new work. A later nextDeferred() call returns that work before checking resolved, so the callback can execute after the event has completed.

Check this.resolved before queueing or dispatching new work.

Proposed fix
 public defer(work?: DeferredWork): void {
+  if (this.resolved) return;
   this.deffered = true;
   if (!work) return;

- Around line 170-171: Replace the single-presence runningGames tracking with
per-app process accounting, such as a count or process identifiers, across the
add/remove lifecycle in the relevant handler methods. Increment when each
process starts, decrement only when that process exits, and clear the app’s
running state only after the final process has exited so removeApp cannot delete
a directory still used by another process.
