#Quantumult X 资源解析器(2020-04-26: 16:20)

本资源解析器作者: Shawn(@XIAO_KOP), 有问题请反馈:@Shawn_KOP_bot

功能: 将节点订阅解析成Quantumult X引用片段, 并提供下列可选参数(已支持 V2RayN/SSR/SS/Trojan/Quanx订阅)

0️⃣ 在订阅链接后加入 "#" 符号后再加参数，不同参数间请使用 "&" 来连接，如:
       "#in=香港+台湾&emoji=1&tfo=1"

1⃣️ 筛选参数 in、out, 分别为保留与排除，多个参数间用"+"号连接, 可直接使用中文(如"in=香港+台湾&out=BGP")

2⃣️ emoji 参数为 emoji=1,2 或-1，为添加或删除节点名中的emoji旗帜（国行设备请用 emoji=2）

3⃣️ udp=1, tfo=1 参数开启udp-relay及fast-open.(默认关闭,且此参数对源类型为Quanx的链接无效)

4⃣️ rename 重命名,rename=旧名@新名, 以及 "前缀@", "@后缀",用"+"连接，如 "rename=香港@HK+[SS]@+@[1X]

5⃣️ info=1，用于打开转换解析器的提示通知(默认关闭)

 */

/**
 * 使用说明，
0⃣️ 在Quantumult X 配置文件中[general] 部分，加入 resource_parser_url=https://raw.githubusercontent.com/KOP-XIAO/QuantumultX/master/Scripts/resource-parser.js
1⃣️ 假设原始订阅连接为: https://raw.githubusercontent.com/crossutility/Quantumult-X/master/server-complete.txt , 
2⃣️ 假设你想要保留的参数为 in=tls+ss, 想要过滤的参数为 out=http+2, 请注意下面订阅链接后一定要加 ”#“ 符号
3⃣️ 则填入 Quanx 节点引用的的总链接为  https://raw.githubusercontent.com/crossutility/Quantumult-X/master/server-complete.txt#in=tls+ss&out=http+2
4⃣️ 填入上述链接并打开的资源解析器开关
