#执行安装脚本
[root@almalinux ~/rust-1.82.0-x86_64-unknown-linux-gnu]# bash install.sh

#安装编译环境gcc
[root@almalinux ~/rust-1.82.0-x86_64-unknown-linux-gnu]# cd
[root@almalinux ~]# yum install gcc git -y
```

### How it works

1. unpack `node_modules.asar` package (in `./resources`)
2. write `hook.js`  into `raven` package directory (raven will be required at the early stage of startup in some application)
3. modify `index.js` of `raven`,injecting require of `hook.js`

> Currently using embedded javascript file (`hooklog.js`)

### Usage

1. modify `hook.js` if you need or enable `no_embed` feature to use specified js (`NO_EMBED_HOOK_JS_PATH`)  at runtime
2. use `cargo build` to make  executable with embedded js or `cargo build --features no_embed` without embedded js
3. Move the program to the electron application directory
4. run


### Compatibility test

- Windows / Typora 1.4.8          PASSED
- Ubuntu / Typora 1.4.7             PASSED

Since macos may adopt different packaging methods and webkit as the execution environment, this tool does not support applications under macos.
