annotationdata.py (OOP版)
|
||
------------------------
|
||
功能：
|
||
- 解析iBooks的AEAnnotation.sqlite数据库，提取所有或指定书籍（assetid/bookid）的笔记。
|
||
- 提供parse_location辅助函数，解析笔记定位信息。
|
||
- 返回结构化的annotations数据，便于后续章节定位与导出。
|
||
|
||
依赖：config.py 统一管理路径和配置项。
|
||
主要接口：AnnotationManager
|
||
- get_annotations(bookid=None)：返回所有或指定assetid的笔记，结构为{assetid: {uuid: {...}}}
|
||
- parse_location(location)：解析ZANNOTATIONLOCATION，返回(idref, filepos)
|
||
依赖：sqlite3, collections, re, os, datetime
