+# Script 脚本
+
+Clash Premium 实现了基于 Python3 的脚本功能, 使用户能够以动态灵活的方式为数据包选择策略.
+
+您可以使用单个 Python 脚本控制整个规则匹配引擎, 也可以定义一些快捷方式, 并与常规规则一起使用. 本页介绍了第一种功能, 有关后者, 请参见[Script Shortcuts 脚本捷径](./script-shortcuts.md).
+
+## 控制整个规则匹配引擎
+
+```yaml
+mode: Script
+
+# https://lancellc.gitbook.io/clash/clash-config-file/script
+script:
+  code: |
+    def main(ctx, metadata):
+      ip = metadata["dst_ip"] = ctx.resolve_ip(metadata["host"])
+      if ip == "":
+        return "DIRECT"
+
+      code = ctx.geoip(ip)
+      if code == "LAN" or code == "CN":
+        return "DIRECT"
+
+      return "Proxy" # default policy for requests which are not matched by any other script
+```
+
+如果您想使用 IP 规则 (即: IP-CIDR、GEOIP 等) , 您首先需要手动解析 IP 地址并将其分配给 metadata:
+
+```python
+def main(ctx, metadata):
+    # ctx.rule_providers["geoip"].match(metadata) return false
+
+    ip = ctx.resolve_ip(metadata["host"])
+    if ip == "":
+        return "DIRECT"
+    metadata["dst_ip"] = ip
+
+    # ctx.rule_providers["iprule"].match(metadata) return true
+
+    return "Proxy"
+```
+
+Metadata 和 Context 的接口定义:
+
+```ts
+interface Metadata {
+  type: string // socks5、http
+  network: string // tcp
+  host: string
+  src_ip: string
+  src_port: string
+  dst_ip: string
+  dst_port: string
+}
+
+interface Context {
+  resolve_ip: (host: string) => string // ip string
+  resolve_process_name: (metadata: Metadata) => string
+  resolve_process_path: (metadata: Metadata) => string
+  geoip: (ip: string) => string // country code
+  log: (log: string) => void
+  proxy_providers: Record<string, Array<{ name: string, alive: boolean, delay: number }>>
+  rule_providers: Record<string, { match: (metadata: Metadata) => boolean }>
+}
+```
