Question

我只是学习使用clang-format。我主要设法配置它以符合我的口味，但我无法弄清楚如何使它缩进extern "C"块。

这是理想的结果：

extern "C" {
    void myFunction() {
        // ...
    }
}

但这就是我得到的：

extern "C" {
void myFunction() {
    // ...
}
}

这是我的配置：

Answer 1

更新版本的clang-format（我相信它是在LLVM 6中引入的）确实为BraceWrapping配置选项实现了AfterExternBlock标志。考虑将其设置为true。

Answer 2

较新版本的 clang-format（clang-format-10 或更高版本）确实实现了 IndentExternBlock 标志

如何在C ++中使用clang-format缩进extern C块？
