@ColorfulBoar 感谢你的批评！
网站是纯 HTML 的，可能在反应上并不是很友好。
Done Right 我其实也看了。能具体说一下哪里“念念不忘 matrix”吗？
谢谢你的指点，我一直想找一些 category theory 的 diagrams 来入门，因为没有找到好的材料，就直接用了一些原始的方法来作图。
最后，tensor 入门在我看的其他几本书中都未涉及（ Linear Algebra by Serge Lang, "Done Right"），所以只是最简单的从 basis 出发做了一些介绍。请问你有什么 tensor 和 penrose diagram 的 reference （书本、文章、笔记等）可以推荐吗？感激不尽。

@WillBC 很不错的资料!
我粗略看了一下,它的 interactive parts 应该是注重于 example,可以直观看到结果.
LAID 的插图比较 generalized, 笔记里也比较少有 examples. 后续或许会增加

@zzl22100048 那或许你目前的做法比较合适。如果需要高效的话可能直接在 Rust 中实现一个函数并在脚本中调用会更快

@zzl22100048 嗯，如果你需要对非 IP 前缀返回上游解析结果的话，可以这样写：
try {
resp.push_answer(create_record(qname, "IN", ttl, 3600, create_a(ip)));
} catch {
return upstreams.send(...);
}
直接把 replace 后的结果放入 create_a 尝试创建 A rdata ，如果 ip 并不是一个合法的 IPv4 地址，那么 create_a 就会出错，然后执行 catch 部分并返回上游结果。
这样做的话可以避免拆分再重建域名部分，更加简单，也可以提升性能。

resp.push_answer(create_record(qname, "IN", ttl, 3600, create_a(ip)));

简单实现了一个 XIP 功能，对于非法格式会返回 SERVFAIL 。可以进一步判断 qtype 来正确支持 A 和 AAAA resource record 。
```yaml
script:
route: |
let resp = query;
resp.header.qr = true;
let ip = query.first_question.qname.to_string();
ip.replace(".xip.io", "");
resp.push_answer(create_record(query.first_question.qname, "IN", 3600, create_a(ip)));
resp
```
```yaml
script:
route: |
let resp = query;
resp.header.qr = true;
let ip = query.first_question.qname.to_string();
ip.replace(".xip.io", "");
resp.push_answer(create_record(query.first_question.qname, "IN", 3600, create_a(ip)));
resp
```

也可以参考 README 中 quickstart 里的示例快速添加 EDNS Client Subnet record:
script:
route: |
let query = query;
// Optionally remove all the existing OPT pseudo-section(s)
// query.clear_opt();
query.push_opt(create_client_subnet(15, 0, "23.62.93.233"));
upstreams.send("secure", query)
script:
route: |
let query = query;
// Optionally remove all the existing OPT pseudo-section(s)
// query.clear_opt();
query.push_opt(create_client_subnet(15, 0, "23.62.93.233"));
upstreams.send("secure", query)

在最新的 build 中，可以参考如下代码实现自定义 response:
```
let resp = query;
// 表明这个 DNS message 是 response
resp.qr = true;
// 在不同的 section 加入 resource record ，目前支持创建 TXT ，A ，AAAA record ，欢迎 file issue 来表明你的需求。
// query.first_question.qname 是第一个 question 的请求“域名”, 3600 是 TTL
resp.push_additional(create_record(query.first_question.qname, "IN", 3600, create_txt("vfs.global")));
resp.push_answer(create_record(query.first_question.qname, "IN", 3600, create_a("127.0.0.1")));
resp.push_answer(create_record(query.first_question.qname, "IN", 3600, create_aaaa("0000:0000:0000:0000:0000:0000:0000:0000")));
