ChuSQL 是采用 Haskell SQL 引擎与 Rust 存储层的数据库项目，提供 TCP 服务、CLI 和 Web 管理端。支持查询优化、快照事务、WAL 崩溃恢复、DOMAIN 自定义类型及用户与角色管理。

项目仓库：[GitHub](https://github.com/TheBadRoger/ChuSQL) · [ChuRepo](https://repo.chunana.cn/ChuNa7a/ChuSQL)。两处均可获取源码，按网络情况选择。

## 快速开始

### 安装

Linux / macOS：

```sh
(curl -fsSL --connect-timeout 10 \
  https://raw.githubusercontent.com/TheBadRoger/ChuSQL/main/scripts/install.sh -o install.sh ||
 curl -fsSL --connect-timeout 10 \
  https://repo.chunana.cn/ChuNa7a/ChuSQL/raw/branch/main/scripts/install.sh -o install.sh) &&
sh install.sh --component web
```

也可从 ChuRepo 下载后执行：

```sh
curl -fsSL \
  https://repo.chunana.cn/ChuNa7a/ChuSQL/raw/branch/main/scripts/install.sh \
  -o install.sh
sh install.sh --component web
```

Windows（PowerShell 里下下来再跑；也有下载 zip 解压的包内安装）：

```powershell
try {
    irm https://raw.githubusercontent.com/TheBadRoger/ChuSQL/main/scripts/install.ps1 -OutFile "$env:TEMP\install.ps1" -TimeoutSec 60 -ErrorAction Stop
} catch {
    irm https://repo.chunana.cn/ChuNa7a/ChuSQL/raw/branch/main/scripts/install.ps1 -OutFile "$env:TEMP\install.ps1" -TimeoutSec 60 -ErrorAction Stop
}
& "$env:TEMP\install.ps1" -Component web
```

ChuRepo 下载方式：

```powershell
irm https://repo.chunana.cn/ChuNa7a/ChuSQL/raw/branch/main/scripts/install.ps1 -OutFile "$env:TEMP\install.ps1"
& "$env:TEMP\install.ps1" -Component web
```

上述命令下载脚本时优先 GitHub，失败后尝试 ChuRepo。脚本安装和更新时也会自动回退：版本查询或发行包下载失败时尝试 ChuRepo；已选定的版本保持不变，校验失败直接报错。两站均无对应发行包时需使用包内安装或源码安装。显式指定其他仓库或归档 URL 时不会回退到官方仓库。

### 启动

```sh
csql
```

启动CLI界面，或

```sh
csql-web
```

启动web界面，默认通过7778端口访问
