我试图通过 Spotify 的 Applescript 库找出检测音轨变化的最佳方法。到目前为止，我已经尝试检查播放器位置——如果它等于 0，它是一个新轨道，并且 Growl 通知再次出现。（如果有人重新开始一首歌等，这通常不起作用。）
我想知道是否更合理的方法是运行一个空闲的 iTunes 脚本并每隔几秒检查一次当前曲目名称是否更改。我担心这可能有点记忆力强。我也无法让这段代码发挥作用。
tell application "System Events"
-- checks for instance of Growl and Spotify, does not run if both programs are not active
set isRunning to ¬
(count of (every process whose name is "Growl")) > 0
(count of (every process whose name is "Spotify")) > 0
end tell
--establish empty variable to be filled by song title later
global latest_song
set latest_song to ""
on idle
tell application "Spotify"
if player state is playing then
copy name of current track to current_tracks_name
-- runs match between last and current song titles
if current_tracks_name is not latest_song then
copy current_tracks_name to latest_song
set who to artist of current track
set onwhat to album of current track
tell application "Growl"
-- Make a list of all the notification types
-- that this script will ever send:
set the allNotificationsList to ¬
{"SpotifyNewTrack"}
-- Make a list of the notifications
-- that will be enabled by default.
-- Those not enabled by default can be enabled later
-- in the 'Applications' tab of the growl prefpane.
set the enabledNotificationsList to ¬
{"SpotifyNewTrack"}
-- Register our script with growl.
-- You can optionally (as here) set a default icon
-- for this script's notifications.
register as application ¬
"Spotify" all notifications allNotificationsList ¬
default notifications enabledNotificationsList ¬
icon of application "Spotify"
-- Send a Notification...
notify with name ¬
"SpotifyNewTrack" title ¬
current_tracks_name description ¬
who application name "Spotify"
end tell
end if
return 5
end if
end tell
end idle
这可能有点复杂，但任何帮助表示赞赏。
