解码iTunes智能播放列表规则。将iTunes智能播放列表转换为Kodi XSP智能播放列表。
itunessmart的Python项目详细描述
iTunes智能播放列表分析器
将智能播放列表信息转换为可读形式。
这个模块是一个python 3实现，基于banshee-itunes-import-pluginbyScott Peterson。
它在windows 10、itunes 12.9.0（64位）和python 3.6上进行了测试。
它不适用于python 2.x。
KODI智能播放列表
您可以使用此交互式脚本将所有iTunes智能播放列表转换为Kodi智能播放列表：
python3 utils/export_xsp.py或python3 -m itunessmart
然后将out/中生成的.xsp文件放在userdata文件夹中。
大多数常见的功能和规则都有两种格式，而且iTunes播放列表通常可以完全转换为Kodi格式。
最大的区别是itunes中的嵌套规则，而kodi中没有这些规则。
但是，嵌套规则可以用子播放列表模拟。这些“helper”播放列表是以前缀“zzzsub”命名的，其规则是md5散列。
运行utils/export_xsp.py时，可以禁用生成子playlists。

文本导出
要将所有播放列表导出到文本文件，请使用python3 utils/export.py
格式
iTunes中的智能播放列表数据保存在itunes music library.xml文件中。
XML文件中播放列表项中的数据是base64编码的二进制数据：
<dict><key>Name</key><string>Example</string><key>Playlist ID</key><integer>123456</integer><key>Playlist Persistent ID</key><string>49C97D85843B04CC</string><key>Parent Persistent ID</key><string>4DA0F774D3F70473</string><key>All Items</key><true/><key>Smart Info</key><data> AQEAAwAAAAIAAAAZAAAAAAAAAAcAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAA== </data><key>Smart Criteria</key><data> U0xzdAABAAEAAAADAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAABYAAAAQAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAABEAAAAAAAAAA8AAAAAAAAAAAAAAAAAAAABAAAA AAAAAA8AAAAAAAAAAAAAAAAAAAABAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAQEAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAB/FNMc3QAAQABAAAAAw AAAAEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAWAAAAEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAARAAAAAAAAAAQAAAAAAAAAAAAAAAAAAAAAQAAAAAAAAAQAAAAAAAAAA AAAAAAAAAAAQAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAFgAAABAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAEQAAAAAAAAAEQAAAAAAAAAAAAAAAAAAAAEA AAAAAAAAEQAAAAAAAAAAAAAAAAAAAAEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAABYAAAAQAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAABEAAAAAAAAABIAAA AAAAAAAAAAAAAAAAABAAAAAAAAABIAAAAAAAAAAAAAAAAAAAABAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAZAAAAEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAARAAAAAAAAABZAAAAAAAAAAAAAAAAAAAAAQAAAAAAAABZAAAAAAAAAAAAAAAAAAAAAQAAA AAAAAAAAAAAAAAAAAAAAAAA </data><key>Playlist Items</key><array><dict><key>Track ID</key><integer>123</integer></dict><dict><key>Track ID</key><integer>124</integer></dict><dict> ... <dict></array></dict>
它可以转换为三种不同的输出格式：
importitunessmartinfo="AQEAAwAAAAIAAAAZ..."criteria="U0xzdAABAAEAAAAD..."parser=itunessmart.Parser(info,criteria)result=parser.resultprint(result.output)print(result.query)print(json.dumps(result.queryTree,indent=2))
文本格式：
Playsisgreaterthan15and[Playsisgreaterthan16orPlaysisgreaterthan17orPlaysisgreaterthan18]andRatingisgreaterthan4
类似sql的格式：
(Plays>15)AND((Plays>16)OR(Plays>17)OR(Plays>18))AND(Rating>4)
以及两个树结构
{"tree":{"and":[["Plays","(Plays > 15)"],{"or":[["Plays","(Plays > 16)"],["Plays","(Plays > 17)"],["Plays","(Plays > 18)"]]},["Rating","(Rating > 4)"]]},"liveupdate":true,"onlychecked":false}
{"fulltree":{"and":[{"field":"Plays","type":"int","operator":"greater than","value":15},{"or":[{"field":"Plays","type":"int","operator":"greater than","value":16},{"field":"Plays","type":"int","operator":"greater than","value":17},{"field":"Plays","type":"int","operator":"greater than","value":18}]},{"field":"Rating","type":"int","operator":"greater than","value":4}]}}
