## 构建
```bash
source $EMCC_HOME/emsdk_env.sh
# once only
# 只需要运行一次
npm install browserify terser node-gyp -g
# once only
# 只需要运行一次
npm i
# 构建左推解析器代码（每次修改 ./bin/build.js 都需要重新运行）

production are :
生成 :
- `./out/vcd.js`
- `./out/vcd.wasm`
move them to your development worksapce.
部署代码：
```bash
# 将生成的 wasm 通过 浏览器化和特殊处理后部署到 render 项目中
source deploy.sh /mnt/c/Users/11934/Project/Digital-IDE/digital-vcd-render
