## Programmable
```
Brook GUI will pass different global variables to the script at different times, and the script only needs to assign the processing result to the global variable out
```
### Introduction to incoming variables

## Debug script
It is recommended to use [tun2brook](https://github.com/txthinking/tun2brook) on desktop to debug with `fmt.println`
## Install CA
https://txthinking.github.io/ca/ca.pem
| OS | How |
| --- | --- |
| iOS | https://www.youtube.com/watch?v=HSGPC2vpDGk |
| Android | Android has user CA and system CA, must be installed in the system CA after ROOT |
| macOS | `nami install mad ca.txthinking`, `sudo mad install --ca ~/.nami/bin/ca.pem` |
| Windows | `nami install mad ca.txthinking`, Admin: `mad install --ca ~/.nami/bin/ca.pem` |
> Some software may not read the system CAyou can use `curl --cacert ~/.nami/bin/ca.pem` to debug
