本页由 DataviewJS 实时计算，笔记有变动时自动刷新，无需任何后台服务。
// ============================================================
// tagfeed-live：Logseq 风格标签实时聚合（标准 DataviewJS 脚本）
//
// 用法：
// 1. 新建一个笔记（例如 00index/标签聚合/标签名.md）
// 2. 在笔记里插入一个 dataviewjs 代码块（三个反引号 + dataviewjs），
// 把本脚本全部粘贴进去
// 3. 只需要改下面「配置区」的两行：
// - targetTag 换成你要聚合的标签（不带 #，中英文都可以；多个标签写成数组 ["a", "b"]）
// - excludedPaths 换成你想排除的文件夹
// 4. 完成。以后任何笔记里出现/删除这个标签，本页自动刷新，
// 不需要跑任何命令（Dataview 会在文件变动后自动重新渲染）。
// ============================================================
// ---------------- 配置区（通常只改这里） ----------------
const targetTag = "Prompt"; // 要聚合的标签（不带 #）；多个标签用数组：["lyric", "歌词"]
const excludedPaths = ["X2.Archived", "00index", "X0.Clippings", "X1.Knomo", "02DS/02copilot", ".agents", ".claude", ".copilot", ".opencode", ".smart-env", ".workbuddy", ".trash"]; // 要排除的文件夹/路径前缀（vault 相对路径）
// 例如：["00index", "模板", "X1.Knomo"]
// 补充说明：
// - 所有隐藏文件/文件夹（. 开头：.agents/.claude/.copilot/.opencode/.smart-env/.workbuddy/.trash 等）与 X.Attachment 始终跳过
// - tagfeed 系统页会自动跳过：静态聚合页（文件头含 <!-- tagfeed 标记）
// 和实时页（frontmatter 带 tagfeed / tagfeed-live 标签），
// 无需手动排除 00index
// - 本脚本所在的当前笔记也会自动跳过
