From 0ca164ee5aca6b8ca1e33b143ee5749254cec5a7 Mon Sep 17 00:00:00 2001 From: Fabio Manganiello Date: Thu, 4 Apr 2024 02:02:51 +0200 Subject: [PATCH] [#297] Removed `music.spotify` backend. 1. I no longer I use a Spotify account (I switched to Tidal after Spotify deprecated libspotify), and I wouldn't like to create one just to test this integration. 2. After a couple of years, the libspotify open fork (Librespot) seems to be still in an unstable stage and it's already been discontinued once - I would avoid rebuilding the integration against a dependency that may change a lot in the near future. --- platypush/backend/button/__init__.py | 0 platypush/backend/music/__init__.py | 0 platypush/backend/music/spotify/__init__.py | 329 ------------------ .../backend/music/spotify/event/__init__.py | 1 - .../backend/music/spotify/event/__main__.py | 26 -- platypush/backend/music/spotify/manifest.yaml | 27 -- platypush/plugins/music/spotify/__init__.py | 4 + 7 files changed, 4 insertions(+), 383 deletions(-) delete mode 100644 platypush/backend/button/__init__.py delete mode 100644 platypush/backend/music/__init__.py delete mode 100644 platypush/backend/music/spotify/__init__.py delete mode 100644 platypush/backend/music/spotify/event/__init__.py delete mode 100644 platypush/backend/music/spotify/event/__main__.py delete mode 100644 platypush/backend/music/spotify/manifest.yaml diff --git a/platypush/backend/button/__init__.py b/platypush/backend/button/__init__.py deleted file mode 100644 index e69de29b..00000000 diff --git a/platypush/backend/music/__init__.py b/platypush/backend/music/__init__.py deleted file mode 100644 index e69de29b..00000000 diff --git a/platypush/backend/music/spotify/__init__.py b/platypush/backend/music/spotify/__init__.py deleted file mode 100644 index 1017db0d..00000000 --- a/platypush/backend/music/spotify/__init__.py +++ /dev/null @@ -1,329 +0,0 @@ -import json -import os -import subprocess -import threading -from typing import Optional, Dict, Any - -from platypush.backend import Backend -from platypush.common.spotify import SpotifyMixin -from platypush.config import Config -from platypush.message.event.music import ( - MusicPlayEvent, - MusicPauseEvent, - MusicStopEvent, - NewPlayingTrackEvent, - SeekChangeEvent, - VolumeChangeEvent, -) -from platypush.utils import get_redis - -from .event import status_queue - - -class MusicSpotifyBackend(Backend, SpotifyMixin): - """ - This backend uses `librespot `_ to turn Platypush into an audio client - compatible with Spotify Connect and discoverable by a device running a Spotify client or app. It can be used to - stream Spotify through the Platypush host.
