README: Aufbau, Bauanleitung und die Entscheidungen, die man sonst für Fehler hält

Das Glyph besteht aus zehn deckenden Pfaden in sehr dunklen Tönen (#1c1f1f bis
#000000). Im App-Icon liegt es auf blauem Verlauf und liest sich als Kristall;
allein auf einer dunklen Menüleiste war es schwarz auf schwarz.

macOS färbt ausschließlich Template-Bilder ein, und die benutzen nur den
Alphakanal — die Facetten verschmelzen dabei zu einer Silhouette. Das ist der
bewusste Tausch: erkennbare Form in hellen wie dunklen Menüleisten statt
Facetten, die man in keiner von beiden sieht.

Eine Fassung mit durchsichtigen Facettenfugen behielte beides. Dafür muss das
SVG entsprechend gezeichnet sein — als Outline statt als Flächen.

+# Onyx
+
+**Notch-Erweiterung für macOS.** Beim Überfahren der Notch fährt ein Panel mit
+eigenen Widgets aus — Kalender, Wetter, Medien, Hardware, Netzwerk, Audio-Mixer,
+Ablage und AirDrop.
+
+Zielgerät: MacBook Pro mit Apple Silicon, macOS 26+.
+
+---
+
+## Bauen
+
+```bash
+xcodegen generate          # erzeugt Onyx.xcodeproj aus project.yml
+open Onyx.xcodeproj        # dann ⌘R
+```
+
+Voraussetzungen: Xcode 26, [XcodeGen](https://github.com/yonaskolb/XcodeGen),
+Signierung mit Team `PP34X97WS3`.
+
+Tests laufen ohne Xcode:
+
+```bash
+cd Packages/OnyxKit && swift test
+```
+
+---
+
+## Aufbau
+
+Die Projektdefinition liegt als `project.yml` vor, nicht als handgepflegte
+`.xcodeproj` — so ist im Diff lesbar, was sich an den Build-Einstellungen ändert.
+
+```
+Onyx/                    App-Target (nicht sandboxed, Hardened Runtime)
+Packages/OnyxKit/        Alle Module als lokales Swift-Package
+  OnyxCore               Einzelinstanz-Sicherung
+  OnyxDesign             Farben, Maße, Bewegung — einzige Quelle
+  OnyxNotch              Panel-Fenster, Geometrie, Zustandsmaschine
+  OnyxWidgetKit          Widget-Protokoll, Layout-Engine, Persistenz
+  OnyxMenuBar            Modul-Protokoll für Menüleisten-Elemente
+  CalendarProvider       EventKit (und später Calendarr)
+  WeatherProvider        WeatherKit + CoreLocation
+  MediaProvider          MediaRemote-Adapter, AppleScript, Medientasten
+Vendor/                  Fremdcode im Quellzustand (siehe unten)
+Spikes/                  Wegwerf-Werkzeuge zur API-Verifikation
+docs/spikes/             Was dabei herauskam — auch die Sackgassen
+```
+
+---
+
+## Entscheidungen, die man sonst für Fehler hält
+
+**Keine App-Sandbox.** Sie ist mit dem privilegierten Helper, mit IOKit und mit
+dem MediaRemote-Adapter unvereinbar. Der App-Group-Container für Calendarr
+bleibt trotzdem erreichbar — auf macOS ist er von der Sandbox unabhängig.
+Nachgemessen in [docs/spikes/D-appgroup.md](docs/spikes/D-appgroup.md).
+
+**TCC-Entitlements trotz fehlender Sandbox.** Bei aktivierter Hardened Runtime
+verlangt macOS `com.apple.security.personal-information.*` auch ohne Sandbox.
+Fehlt eine davon, erscheint der Berechtigungsdialog gar nicht erst — ohne
+Fehlermeldung. Das hat einen halben Abend gekostet:
+[docs/spikes/E-tcc-hardened-runtime.md](docs/spikes/E-tcc-hardened-runtime.md).
+
+**`ENABLE_DEBUG_DYLIB = NO`.** Xcode lagert im Debug-Build den Programmcode in
+eine eigene dylib aus. TCC ordnet Berechtigungsanfragen dann dem verbleibenden
+Rumpf zu, der weder Info.plist noch Entitlements trägt.
+
+**Eigenes Einstellungsfenster.** SwiftUIs `Settings`-Szene öffnet über einen
+privaten Selektor, der bei Apps ohne Menüleiste unzuverlässig ankommt.
+
+**Der MediaRemote-Adapter wird nicht gelinkt.** Er wird von `/usr/bin/perl`
+geladen, einem berechtigten Systemprogramm — im eigenen Prozess greift Apples
+Entitlement-Prüfung und es käme nichts an.
+

+# MediaRemote Adapter
+
+Get now playing information using the MediaRemote framework
+on all macOS versions, including 15.4 and above.
+
+This works by using a system binary &ndash; `/usr/bin/perl` in this case &ndash;
+which is entitled to use the MediaRemote framework
+and by dynamically loading a custom helper framework
+that prints real-time updates to stdout.
+
+## Example
+
+Install the [media-control](https://github.com/ungive/media-control)
+CLI tool to see this project in action. Works on all macOS versions:
+
+```
+$ brew tap ungive/media-control
+$ brew install media-control
+$ media-control stream
+```
+
+## Usage
+
+This project provides a Perl script
+with a well-defined CLI interface that you can invoke from your app
+in order to read now playing information and control media players.
+The [mediaremote-adapter.pl](./bin/mediaremote-adapter.pl) script
+needs to be bundled with your app,
+alongside the `MediaRemoteAdapter.framework`
+and optionally the `MediaRemoteAdapterTestClient`
+which are exposed as CMake targets in [CMakeLists.txt](./CMakeLists.txt).
+You can find instructions to build the framework in the next section.
+
+The script must then be invoked like this:
+
+```
+/usr/bin/perl /path/to/mediaremote-adapter.pl /path/to/MediaRemoteAdapter.framework COMMAND
+```
+
+`COMMAND` is a placeholder for one of the commands documented below.
+
+For the `test` command the `NowPlayingTestCMediaRemoteAdapterTestClientlient` must be passed
+as an additional argument:
+
+```
+/usr/bin/perl /path/to/mediaremote-adapter.pl /path/to/MediaRemoteAdapter.framework /path/to/MediaRemoteAdapterTestClient test
+```
+
+For ease of use you can also always pass the path to the test client:
+
+```
+/usr/bin/perl /path/to/mediaremote-adapter.pl /path/to/MediaRemoteAdapter.framework /path/to/MediaRemoteAdapterTestClient COMMAND
+```
+
+For more help on available commands read below or omit the `COMMAND` argument.
+
+> [!WARNING]
+> This project is still in development
+> and the API may experience breaking changes across minor revisions.
+
+> [!NOTE]
+> For a maintained Swift package look at this excellent fork:
+> https://github.com/ejbills/mediaremote-adapter
+
+## Build from source
+
+```
+$ git clone https://github.com/ungive/mediaremote-adapter.git
+$ cd mediaremote-adapter
+$ mkdir build && cd build
+$ cmake ..
+$ cmake --build .
+$ cd ..
+$ FRAMEWORK_PATH=$(realpath ./build/MediaRemoteAdapter.framework)
+$ /usr/bin/perl ./bin/mediaremote-adapter.pl "$FRAMEWORK_PATH" stream
+```
+
+This creates the `MediaRemoteAdapter.framework` in the build directory,
+which must be *bundled* with your app, but *not linked against*.
+The framework is only used by the script
+and must merely be passed as a script argument.
+
+If you want to be able to test whether the adapter still works,
+which can be useful to e.g. automatically fall back to AppleScript,
+you need to also bundle the `MediaRemoteAdapterTestClient` executable with your app
+and pass it as an additional argument:
+
+```
+$ HELPER_PATH=$(realpath ./build/MediaRemoteAdapterTestClient)
+$ /usr/bin/perl ./bin/mediaremote-adapter.pl "$FRAMEWORK_PATH" "$HELPER_PATH" test
+```
+
+An exit code of `0` then means the adapter is functional and safe to use.
+
+The framework and test executable are built for the following architectures:
+`x86_64` `arm64`
+

+
+### get
+
+Prints now playing information once with all available metadata.
+
+Output is encoded as JSON and characterized by either `null`
+or a dictionary with any of the following keys:
+
+> `bundleIdentifier`
+`parentApplicationBundleIdentifier`
+`playing`
+`title`
+`artist`
+`album`
+`duration`
+`elapsedTime`
+`timestamp`
+`artworkMimeType`
+`artworkData`
+`chapterNumber`
+`composer`
+`genre`
+`isAdvertisement`
+`isBanned`
+`isInWishList`
+`isLiked`
+`isMusicApp`
+`playbackRate`
+`prohibitsSkip`
+`queueIndex`
+`radioStationIdentifier`
+`repeatMode`
+`shuffleMode`
+`startTime`
+`supportsFastForward15Seconds`
+`supportsIsBanned`
+`supportsIsLiked`
+`supportsRewind15Seconds`
+`totalChapterCount`
+`totalDiscCount`
+`totalQueueCount`
+`totalTrackCount`
+`trackNumber`
+`uniqueIdentifier`
+`contentItemIdentifier`
+`radioStationHash`
+`mediaType`
+
+The following mandatory keys never have a null value:
+`bundleIdentifier`
+`playing`
+`title`.
+If any of the mandatory keys cannot be determined,
+the command prints `null`.
+Media without a title is considered invalid.
+
+The `mediaType` may contain one of the following values:
+- `MRMediaRemoteMediaTypeMusic`
+- `kMRMediaRemoteNowPlayingInfoTypeAudio`
+- Possibly others, this key is not very well documented
+
+**Caveats**
+
+Metadata such as `artworkData` and `artworkMimeType`
+often takes a bit of time to load
+and may not appear in the output in all cases.
+Do not rely on this key to be present reliably.
+Either use the `stream` command or poll `get` regularly,
+to ensure you get the artwork data *eventually*.
+
+**Options**
+
+`--now`&ensp;Adds an `elapsedTimeNow` key with an estimation of the current
+elapsed playback time. This estimation may be off by up to a second.
+To determine a more accurate time without polling `get` continuously,
+calculate it using the `elapsedTime` and `timestamp` keys. `elapsedTime`
+contains the elapsed time at the time that is stored in `timestamp`.
+
+`--micros`&ensp;Replaces the following keys with microsecond equivalents:
+
+| Original key     | Converted key name     | Comment                   |
+|------------------|------------------------|---------------------------|
+| `duration`       | `durationMicros`       | -                         |
+| `elapsedTime`    | `elapsedTimeMicros`    | -                         |
+| `elapsedTimeNow` | `elapsedTimeNowMicros` | Only present with `--now` |
+| `timestamp`      | `timestampEpochMicros` | Converted to epoch time   |
+
+`--no-artwork`&ensp;Omits the `artworkData` and `artworkMimeType` keys
+from the payload. Useful for consumers that do not render artwork,
+since this avoids emitting several hundred kilobytes of base64-encoded
+image data per update.
+
+---
+
+### stream
+
+Streams now playing information updates in real-time
+until the script receives a SIGTERM signal.
+
+Output is encoded as JSON and characterized by
+a dictionary with the following keys:
+
+> `type`
+`diff`
+`payload`
+
+`type` is always a string with the value `"data"`.
+
+`payload` contains the now playing information and is a dictionary
+that is structurally identical to the output of the `get` command,
+with the same keys. The dictionary itself is never `null`.
+No keys are set at all,
+when no media player is reporting now playing information.
+Some keys may have a `null` value,
+when the media player reports `null` for them (this happens rarely, if ever).
+Any key may be `null`, when `diff` is set to true and the key vanishes.
+
+`diff` is a boolean that indicates whether the `payload`
+contains only fields whose values have been updated.
+When set to `false`,
+the payload is to be considered the current now playing state
+with all available keys and their values,
+regardless of any payloads that have been sent in the past.
+When set to `true` on the other hand,
+the last sent non-diff payload must be updated with these new values,
+in order to have a representation of the the current now playing state.
+When a key is not present anymore, it's set to `null` in the payload
+and its previous value should be removed.
+**Diffing is enabled by default, but can be disabled with a command line flag.**
+
+**Options**
+
+`--no-diff`&ensp;Disables diffing. `diff` is always `false`
+and `payload` always contains all current information.
+
+`--debounce=N`&ensp;Adds a debounce delay in milliseconds
+between the point where changes are detected
+and when they are printed.
+If a new update comes in during delaying,
+the delay is restarted and all updates are merged.
+This is useful to prevent bursts of smaller updates.
+The default is 0.
+
+`--micros`&ensp;Identical to the `--micros` option of the `get` command.
+
+`--no-artwork`&ensp;Identical to the `--no-artwork` option of the `get`
+command. Particularly useful with `stream` with the `--no-diff` parameter,
+since it otherwise re-emits the full artwork payload on every update.
+
+**Experimental options**
+
+`--experimental-peculiar-debounce:BUNDLE_ID=N`&ensp;
+Adds a debounce delay in milliseconds for the case when the media player
+with the given bundle identifier (`BUNDLE_ID`) reports metadata that
+contains parts of the previous track and parts of the next track,
+but doesn't contain the full metadata of the next track.
+Whenever the track title changes,
+the update for it is either delayed for the given debounce delay
+or the update is printed when all other metadata updated as well,
+whichever happens earlier.
+Currently only `com.tidal.desktop` can be passed for `BUNDLE_ID`,
+since it is the only media player that is known to have this issue.
+A value of `1000` for `N` is recommended for TIDAL specifically.
+
+---
+
+### send COMMAND
+
+Sends a MediaRemote command to the now playing application.
+
+The value for `COMMAND` must be a valid ID from the table below.
+
+| ID | MediaRemote key         | Description                   |
+|:--:|-------------------------|-------------------------------|
+| 0  | kMRPlay                 | Start playback                |
+| 1  | kMRPause                | Pause playback                |
+| 2  | kMRTogglePlayPause      | Toggle between play and pause |
+| 3  | kMRStop                 | Stop playback                 |
+| 4  | kMRNextTrack            | Skip to the next track        |
+| 5  | kMRPreviousTrack        | Return to the previous track  |
+| 6  | kMRToggleShuffle        | Toggle shuffle mode           |
+| 7  | kMRToggleRepeat         | Toggle repeat mode            |
+| 8  | kMRStartForwardSeek     | Start seeking forward         |
+| 9  | kMREndForwardSeek       | Stop seeking forward          |
+| 10 | kMRStartBackwardSeek    | Start seeking backward        |
+| 11 | kMREndBackwardSeek      | Stop seeking backward         |
+| 12 | kMRGoBackFifteenSeconds | Go back 15 seconds            |
+| 13 | kMRSkipFifteenSeconds   | Skip ahead 15 seconds         |
+
+---
+
+### seek POSITION
+
+Seeks to a specific timeline position with the now playing application.
+
+The value for `POSITION` must a valid positive integer.
+The unit is microseconds.
+
+---
+
+### shuffle MODE
+
+Sets the shuffle mode.
+
+The value for `MODE` must be a valid ID from the table below.
+
+| ID | Description    |
+|:--:|----------------|
+| 1  | Disable        |
+| 2  | Shuffle albums |
+| 3  | Shuffle tracks |
+
+---
+
+### repeat MODE
+
+Sets the repeat mode.
+
+The value for `MODE` must be a valid ID from the table below.
+
+| ID | Description     |
+|:--:|-----------------|
+| 1  | Disable         |
+| 2  | Repeat track    |
+| 3  | Repeat playlist |
+
+---
+
+### speed SPEED
+
+Sets the playback speed.
+
+The value for `SPEED` must be a valid positive integer.
+
+---
+
+### test
+
+Tests if the adapter is entitled to use the MediaRemote framework
+and if it is able to execute any of the supported commands without failure.
+An exit code of 0 means the adapter is functional and safe to use.
+
+This can be integrated into your app
+to help confirm that the adapter is still functional and if not,
+fall back to other methods for media detection (e.g. AppleScript),
+since future macOS updates may break MediaRemote access again.
+
+#### Usage
+
+```
+/usr/bin/perl /path/to/mediaremote-adapter.pl /path/to/MediaRemoteAdapter.framework /path/to/MediaRemoteAdapterTestClient test
+```
+
+Note that the `test` command requires the absolute path
+to the `MediaRemoteAdapterTestClient` executable after the framework path.
+For ease of use you can always pass the path to the test client executable,
+even when using other commands, like `get` or `stream`.
+
+#### Output
+
+An exit code of `0` indicates that the adapter is still functional
+and can safely be used to detect media.
+Any other exit indicates that the adapter is likely broken.
+
+If you ever get an exit code other than `0`,
+please [report this](https://github.com/ungive/mediaremote-adapter/issues). Thank you!
+
+#### How this works
+
+1. Now playing information is attempted to be read normally using `get`
+2. If no media is detected, the `MediaRemoteAdapterTestClient` helper process is launched to simulate media playback
+3. While the helper process is running, now playing information is attempted to be read again using `get`
+4. Afterwards the helper process is terminated
+5. If any of the `get` attempts yielded media information, the command exits with an exit code of `0`
+6. Otherwise the command exits with an exit code of `1`
+
+> [!WARNING]
+> **May interfere with other apps using MediaRemote**  
+> The test can create a fake media entry that will briefly appear
+as the now playing application.
+This only happens when no other media is playing.
+Since the helper process has no bundle identifier,
+it is mostly ignored by the `stream` and `get` commands —
+`stream` won't update, and `get` will print `null`.
+
+---
+
+## Built-in fixes
+
+This library has some fixes built-in
+to accomodate for inconsistencies within the MediaRemote framework:
+
+- Artwork data sometimes unloads for a brief moment,
+  e.g. when changing the current timeline position of a track.
+  To combat this, artwork data is reused when the track has not changed,
+  the track had artwork data before and the artwork data has disappeared.
+  This fix is applied when using the `stream` command
+
+If you need a way to disable any or all of these fixes,
+please open an issue or create a pull request.
+
+---
+
+## Implementation notes
+
+- Consider `NSJSONSerialization` for JSON deserialization.
+  This is what is used for encoding
+- You can use `NSData`'s `initWithBase64EncodedString`
+  for decoding of base64 data
+- Every line printed to stderr is an error message.
+  If the script did not exit with a non-zero exit code,
+  then any of these errors are non-fatal and can be safely ignored
+- Other apps using MediaRemote Adapter may run `test` which should not interfere with the `stream` and `get` commands, but will generate a missing bundle identifier error message, which can be ignored. See the `test` command section for more information.
+- You should not reinvoke the script when a fatal error occurs
+  (non-zero exit code)
+- Make sure to pass the absolute path of the bundled framework and helper executable
+  as arguments and not a relative path
+
+## Why this works
+
+According to the findings by [@My-Iris](https://github.com/Mx-Iris) in
+[this comment](https://github.com/aviwad/LyricFever/issues/94#issuecomment-2746155419)
+processes with a bundle identifier starting with `com.apple.`
+are granted permission to access the MediaRemote framework.
+The Perl platform binary `/usr/bin/perl`
+is reported as having the bundle identifier `com.apple.perl` (or a variation).
+
+You can confirm this by streaming log messages using the Console.app
+whilst running the script:
+
+`default	14:44:55.871495+0200	mediaremoted	Adding client <MRDMediaRemoteClient 0x15820b1a0, bundleIdentifier = com.apple.perl5, pid = 86889>`
+
+## Motivation
+
+This project was created due to the MediaRemote framework
+being completely non-functional when being loaded directly from within an app,
+starting with macOS 15.4 (see the numerous issues linked below).
+
+The aim of this project is to provide a tool (and perhaps soon a full library)
+that serves as a fully functional alternative to using MediaRemote directly
+and perhaps to inspire Apple to give us a public API
+to read now playing information and control media playback on the device
+(see the note at the top of this file).
+
+## Projects that use this library
+
+- [Now Playing Display](https://www.gxlabs.co/now-playing/): A macOS "now playing" hardware display for the Seeed XIAO ESP32-C6 paired with the Seeed Round Display for XIAO. Shows album art, track info, progress, and playback controls on a 240x240 circular TFT — connected over USB. Source code: https://github.com/gxlabs/now-playing-device
+- [Music Presence](https://musicpresence.app) is a cross-platform desktop application
+  for showing what you are listening to in your Discord status.
+  It uses this library since version [2.3.1](https://github.com/ungive/discord-music-presence/releases/tag/v2.3.1)
+  to detect media from all media players again. Website: https://musicpresence.app
+- [media-control](https://github.com/ungive/media-control)
+  is a CLI tool to control and observe media playback on any macOS version.
+  You can install it directly via brew: `$ brew tap ungive/media-control && brew install media-control`. Source code: https://github.com/ungive/media-control

+## Acknowledgements
+
+Thank you [@Alexander5015](https://github.com/Alexander5015) for implementing the `test` command,

+# Hardened Runtime verlangt eigene TCC-Entitlements
+
+Aufgetreten am 10.08.2026 beim Kalender-Widget. Aufwendig zu finden, in einer
+Zeile zu beheben — deshalb hier festgehalten, bevor es bei Standort, Apple
+Events und Audio erneut zuschlägt.
+
+## Erscheinungsbild
+
+`EKEventStore.requestFullAccessToEvents()` kehrt nach wenigen Millisekunden mit
+`false` zurück. Kein Fehler, kein Dialog. `authorizationStatus` bleibt auf
+`notDetermined`. In den Systemeinstellungen taucht die App **gar nicht** auf —
+und dort lässt sich auch nichts von Hand nachtragen, denn der Kalenderbereich
+hat kein Pluszeichen. Einträge entstehen ausschließlich durch eine erfolgreiche
+Anfrage. Man sitzt also in einer Sackgasse ohne jede Fehlermeldung.
+
+## Ursache
+
+```
+tccd: Prompting policy for hardened runtime; service: kTCCServiceCalendar
+      requires entitlement com.apple.security.personal-information.calendars
+      but it is missing

+
+Bei aktivierter Hardened Runtime verlangt TCC diese Entitlements — **auch ohne
+App-Sandbox.** Die verbreitete Annahme, sie gälten nur für sandboxed Apps, ist
+falsch. Ohne sie zeigt macOS den Dialog nicht einmal an.
+
+## Behebung
+
+In `Onyx.entitlements`, je nach genutztem Dienst:
+
+| Dienst | Entitlement |
+|---|---|
+| Kalender | `com.apple.security.personal-information.calendars` |
+| Standort | `com.apple.security.personal-information.location` |
+| Apple Events (AppleScript) | `com.apple.security.automation.apple-events` |
+| Audioaufnahme / Process Taps | `com.apple.security.device.audio-input` |
+| Kontakte | `com.apple.security.personal-information.addressbook` |
+
+## Wie es gefunden wurde
+
+Nicht durch Nachdenken, sondern durch Ausschluss. Entscheidend war eine
+**minimale Test-App**: normales Fenster, im Vordergrund, gleiches Zertifikat,
+nichts von Onyx darin — und sie scheiterte identisch. Damit war belegt, dass es
+nicht an Onyx lag, und die Suche konnte sich auf die Umgebung verlagern.
+
+Der Weg dorthin führte über mehrere falsche Fährten, die hier stehen, damit sie
+niemand zweimal geht:
+
+- **`log show` wurde von zsh abgefangen** („too many arguments"). Weil stderr
+  umgeleitet war, sah die leere Ausgabe wie ein Befund aus. `/usr/bin/log`
+  benutzen.
+- **`promptPolicy = 0`** im Protokoll gehörte zu `kTCCServiceReminders`, nicht
+  zum Kalender. Der bekam durchgehend `promptPolicy = 4`.
+- **Bildschirmzeit** stand unter Verdacht (ein `digital_health_restrictions`-Profil
+  ist installiert), schränkt aber nur Game Center und die Zeitsynchronisation ein.
+- **Ein verklemmter TCC-Eintrag** existierte tatsächlich und wurde mit
+  `tccutil reset Calendar <bundle-id>` entfernt — behob das Problem aber nicht.
+
+Zwei Nebenbefunde, die für sich schon Fehler waren und mitbehoben wurden:
+
+- **`ENABLE_DEBUG_DYLIB`** (Xcodes Voreinstellung im Debug-Build) lagert den
+  Programmcode in eine eigene dylib aus. Das Hauptprogramm ist dann nur ein
+  Rumpf, und die TCC-Anfrage erreichte `tccd` überhaupt nicht. Steht jetzt auf `NO`.
+- **SwiftUIs `Settings`-Szene** wird über den privaten Selektor
+  `showSettingsWindow:` geöffnet und kommt bei `.accessory`-Apps unzuverlässig
+  an. Onyx führt sein Einstellungsfenster deshalb selbst.
+
+## Merksatz
+
+Wenn ein Berechtigungsdialog ausbleibt, ohne dass irgendwo ein Fehler steht:
+zuerst `/usr/bin/log show --predicate 'process == "tccd"'` lesen. Der Grund
+steht dort im Klartext — und nirgendwo sonst.
