# @punktfunk/plugin-playnite

Sync your **[Playnite](https://playnite.link)** library into the Punktfunk host game library. Every
store and emulator Playnite manages — Steam, GOG, Epic, Xbox, itch, RetroArch, standalone emulators,
manually-added games — shows up in Punktfunk's grid on every client, and launching a title hands it
straight back to Playnite, which performs the real launch.

It has two halves, both on the **same Windows box** as the Punktfunk host:

```
┌─────────────────────────────┐        ┌──────────────────────────────────────────┐
│ Playnite                    │        │ Punktfunk host  (this plugin, in the       │
│  └ Punktfunk Sync extension │  JSON  │ scripting runner)                          │
│     writes                  │ ─────▶ │  reads punktfunk-library.json, embeds art, │
│     punktfunk-library.json  │        │  PUT /library/provider/playnite            │
└─────────────────────────────┘        └──────────────────────────────────────────┘
```

- **The Playnite exporter** (`exporter/`, C#) is a tiny [GenericPlugin](https://api.playnite.link/docs/tutorials/extensions/genericPlugins.html)
  that writes your library to a JSON file whenever it changes. Playnite locks its library database
  while running, so reading it from *inside* Playnite is the only robust way — this is that adapter,
  and nothing more.
- **This plugin** (TypeScript, on [`@punktfunk/host`](https://git.unom.io/unom/punktfunk/src/branch/main/sdk))
  watches that file and reconciles it into the host library as the `playnite` provider, with a
  console-hosted web UI. Zero-config auth via the runner.

## Install

Two one-time steps.

### 1 · This plugin (on the host)

```powershell
cd "$(punktfunk config-dir)\plugins"          # e.g. C:\ProgramData\punktfunk\plugins
# bunfig.toml points the @punktfunk scope at the registry (once)
bun add @punktfunk/plugin-playnite
Enable-ScheduledTask PunktfunkScripting        # enable the scripting runner if it isn't already
```

Open the Punktfunk console — a **Playnite** entry appears in the nav. (Headless box without the
console? The engine is fully functional from a `config.json` alone — see [Headless](#headless--cli).)

### 2 · The Punktfunk Sync extension (in Playnite)

Download **`punktfunk-sync.pext`** from the [latest CI build](https://git.unom.io/unom/punktfunk-plugin-playnite/actions)
(the `exporter` job's artifact) and **double-click it** — Playnite installs it like any add-on.
Restart Playnite once.

That's it. The console's **Playnite** page shows "Exporter connected" and your games sync within
seconds of any library change.

> The console page can also **deploy the exporter for you** if you'd rather not handle the `.pext` —
> it drops the extension into `%APPDATA%\Playnite\Extensions\` and asks you to restart Playnite.
> (Best-effort: it needs read/write access to the interactive user's `%APPDATA%`; the `.pext` is the
> reliable fallback.)

## Launching

Each title syncs with a launch command of `start "" "playnite://playnite/start/<gameId>"`. The host
runs that in the interactive Windows session, so **Playnite** owns the actual launch — the correct
store client or emulator, exactly as if you'd hit Play in Playnite. No per-store launch mapping to
maintain.

## Box art

Playnite stores cover art as **local files** on the host. Rather than shipping image bytes in the
reconcile (which doesn't scale — a large library blows past the host's request-body limit), the plugin
sends the local file **path** and the host serves the cover through its art proxy
(`/library/art/…`, exactly like Steam art). The payload stays tiny at any library size.

| `art.mode`   | Behaviour                                                        |
|--------------|-----------------------------------------------------------------|
| `host`       | **Default.** Send the cover's local path; the host serves the bytes. Scales to thousands of titles. Requires a host with the provider-art proxy. |
| `dataurl`    | Inline the cover as a size-capped `data:` URL (`maxBytes` caps one image). Self-contained, but for **small** libraries only — a big one exceeds the host's body limit. |
| `off`        | Sync titles with no art (lightest payload).                     |

`art.includeBackground` additionally serves the Playnite background as `hero` art (off by default).

## Filters

| Key                     | Default | Meaning                                                        |
|-------------------------|---------|----------------------------------------------------------------|
| `filter.installedOnly`  | `true`  | Only sync games Playnite marks installed.                      |
| `filter.includeHidden`  | `false` | Include games flagged Hidden in Playnite.                      |
| `filter.sources`        | `[]`    | If non-empty, keep only these sources (`"Steam"`, `"GOG"`…). Case-insensitive. |
| `filter.excludeSources` | `[]`    | Drop these sources.                                            |

Edit them in the console's **Playnite** page, or in `config.json` directly.

## Headless / CLI

The plugin owns `<config_dir>/playnite/config.json` (see [`config.example.json`](./config.example.json)).
It's fully functional from that file alone. A debug CLI mirrors the engine:

```sh
bunx punktfunk-plugin-playnite where       # where the exporter output was found (+ probed paths)
bunx punktfunk-plugin-playnite preview     # the desired library — no host write
bunx punktfunk-plugin-playnite sync        # reconcile into the live library
bunx punktfunk-plugin-playnite uninstall   # remove every entry this plugin owns
```

For a host without the console, set `ui.standalone: true` and a password
(`bunx punktfunk-plugin-playnite set-password <pw>`); the UI then serves on `ui.port` (default 47994).

## Requirements

- A **Windows** Punktfunk host running the scripting runner (`punktfunk-scripting`).
- **Playnite** on the same box, with the Punktfunk Sync extension installed.
- The mgmt-API provider reconcile is loopback + token; the runner supplies both automatically.

## Build from source

```sh
bun install
bun run build:all       # backend (dist/) + SPA (dist/ui/)
bun test
```

The exporter (needs the .NET SDK; builds net462 on any OS via reference assemblies):

```sh
dotnet build exporter/PunktfunkSync.csproj -c Release
# package the .pext:
( cd exporter/bin/Release && zip -j ../../../punktfunk-sync.pext extension.yaml PunktfunkSync.dll )
```
