*配置工具链也是一门学问*

# 开发工具选择

<Info>
  工欲善其事，必先利其器
</Info>

* [Visual Studio Code](https://www.bing.com/ck/a?!&\&p=ba3366210734759ca6c2ff0d8e4d6f20c38c25a26de1a59524eef47831e1732aJmltdHM9MTc4NzcwMjQwMA\&ptn=3\&ver=2\&hsh=4\&fclid=3a0b8182-881b-6bf4-0357-963f89946ab0\&u=a1aHR0cHM6Ly9jb2RlLnZpc3VhbHN0dWRpby5jb20v\&ntb=1)
* [CLion](https://www.jetbrains.com/clion/)
* [Visual Studio IDE](https://visualstudio.microsoft.com/zh-hans/vs/)

我比较喜欢 Jetbrains 家的 IDE，选择 CLion 作为开发工具，可能是 IDEA 的原因，Jetbrains 家的 IDE 上手都比较快

# 工具链选择

<GitHub.Repo repo="mstorsjo/llvm-mingw" />

当然是选择 LLVM MinGW 啦

一般选择 [llvm-mingw-20260616-ucrt-x86\_](https://github.com/mstorsjo/llvm-mingw/releases/download/20260616/llvm-mingw-20260616-ucrt-x86_64.zip)[64.zip](http://64.zip) ，下载 release 然后解压工具链存放问题，然后添加 Path 到环境变量

然后 CLion 配置工具链这样，直接添加即可，然后在 Cmake 工具链处添加选择的工具链，例如 LLVM

然后随便创建一个新的项目，写点代码看看

```cpp theme={null}
#include <cstdio>

auto main() -> int {
    printf("Hello, World!");
    return 0;
}
```

# 关于格式化

`.clang-format` 的一些自用配置

```yaml .clang-format expandable theme={null}
