Calibre 书库书名清洗 & 作者提取 Skill
概述
清洗 Calibre 书库中因从 txt 文件自动导入而产生的损坏书名,同时从书名中提取作者信息并更新到作者字段。适用于 Calibre 书库路径 /home/yangxuan/calibre/books。
前置条件
- Calibre 数据库路径:
/home/yangxuan/calibre/books - 元数据文件:
/home/yangxuan/calibre/books/metadata.db - 需要
calibre-debug或calibrePython 环境(使用LibraryDatabaseAPI) - 运行前须停止其他 Calibre 进程(桌面版、Calibre-Web Docker)
- 运行前必须备份
metadata.db
作者提取规则(从书名中提取)
需要匹配的作者格式(基于实际书库数据)
| 格式 | 示例 | 正则 |
|---|---|---|
作者:xxx(中文冒号) |
...作者:镜欲 |
作者[::]\s*([^\s,,、\))]+) |
作者:xxx(英文冒号) |
...作者:镜欲 |
同上 |
-xxx(英文 dash 结尾) |
善良的美艳妈妈-糠麸 |
-([^-()【】\[\]]+)$ |
翻译:xxx |
...翻译:kkmanlg |
翻译[::]\s*([^\s,,、\))]+) |
BY xxx(英文 BY) |
...BY狱厨 |
\b[Bb][Yy]\s+([^\s,,、\))]+) |
&xxx(and 符结尾) |
...&axenic |
&([^&()【】\[\] ]+)$ |
提取策略
- 优先匹配精确的"作者:"标记(最可靠)
- 失败后尝试
-xxx结尾(短作者名) - 再尝试
翻译:、BY、&xxx等 - 如果提取到的作者名仍是乱填的(如
正文、第01章、【内容简介】),跳过,标为 Unknown
排除项(以下不是真作者)
正文、内容简介第\d+[章节](章节名)- 长度 > 30 字符的内容摘要

shorten(s, max_bytes=120)
将字符串截断到指定字节数,避免因 UTF-8 中文字符跨字节而损坏。

if len(encoded) <= max_bytes:
return s
try:
return encoded[:max_bytes].decode('utf-8')
except:
return encoded[:max_bytes-3].decode('utf-8', errors='ignore')

# 移除 HTML 标签
t = re.sub(r'<[^>]+>', '', t)
# 替换 _BR_ / _BR 标记
t = re.sub(r'_BR_', ' ', t, flags=re.IGNORECASE)
t = re.sub(r'_BR(?![a-zA-Z])', ' ', t)
# 移除 _fontxxx_ / _imgxxx_ 标记
t = re.sub(r'_font[^_]*_', '', t)
t = re.sub(r'_img[^_]*_', '', t)
# 合并多余空格
t = re.sub(r'\s+', ' ', t).strip()

# 移除控制字符

运行清洗脚本
# 停服务 + 备份
cd /home/yangxuan/calibre
docker compose down
cp books/metadata.db books/metadata.db.backup.$(date +%Y%m%d)
killall calibre 2>/dev/null
# 执行
calibre-debug /tmp/fix_titles_v2.py
# 重启
docker compose up -d
已知问题
set_metadata 报 Errno 36 文件名过长
当 author_sort 字段(基于作者名生成)超 80 字节时,Calibre 更新路径会触及 ext4 255 字节限制。此时需先清理极长作者名:
sqlite3 /home/yangxuan/calibre/books/metadata.db "
UPDATE authors SET name='Unknown' WHERE LENGTH(name) > 30;
"
然后重新执行脚本。
