## Mix Assertion, Logging, Unit Testing and Fuzzing with ZeroErr Build Safer Modern C++ Application Speaker: Xiaofan Sun Date: Sep 19, 2024 ## Self-Introduction • Got my Ph.D. from UC, Riverside last std::unique_ptr Class from third-party library: llvm::Value* ## Logging the Data // LOG(INFO) << Data; // ASSERT(a > b, "A > B is not true", a, b); std::ostream& operator<<(std::ostream& out, llvm::Value* data); ## Logging the Data • Namespace pollution • Hard to implement with template • No extensibility • No customization

CMake # 现代 CMake 模块化项目管理指南 彭于斌 (@archibate) 课件 & 源码：https://github.com/parallel101/course 往期录播：https://space.bilibili.com/263032155 ## 第一章：文件 / 目录组织规范 基于 CMake 的 C/C++ 项目，如何优雅地、模块化地组织大量源文件？ ## 推荐的目录组织方式 目录组织格式： • 项目名 /include/ 项目名 / 模块名 .h • 项目名 /src/ 模块名 .cpp • CMakeLists.txt 中写： • target include directories(项目名 PUBLIC include) • 源码文件中写： • #include < 项目名 / 模块名 .h> • 项目名:: 函数名 (); ## 推荐的目录组织方式 推荐的目录组织方式 - 头文件（项目名 /include/ 项目名 / 模块名 .h）中写： • #pragma once • namespace 项目名 { • void 函数名(); • } • 实现文件（项目名 /src/ 模块名 .cpp）中写： • #include < 项目名 / 模块名 .h> • namespace 项目名 { • void 函数名 () {
