Cppinsights
cppinsights 是一个 C++ 编译器可视化和静态分析工具，使用 Clang 前端将源代码解析为抽象语法树。它作为一个源到源 (source-to-source) 转换器，重写 C++ 代码，使隐式编译器行为和隐藏操作变得明确且可见。
该工具专门用于展开复杂的语言结构，例如扩展协程的内部机制以可视化挂起和恢复逻辑。它还揭示了模板实例化期间生成的实际代码，并将隐式编译器操作（包括结构化绑定和特殊成员函数）转换为显式源代码表示。
其他功能包括 using 语句的解析以及 C++ 类继承层次结构的结构图生成。
Features
- C++ Source-to-Source Transformers - Rewrites original C++ code into an expanded version by replacing implicit compiler operations with explicit statements.
- AST-to-Source Generators - Produces explicit source representations by traversing the Clang abstract syntax tree to reflect lowered language semantics.
- Compiler Behavior Visualizers - Visualizes how a C++ compiler interprets source code by expanding implicit operations into explicit, readable code.
- Coroutine Machinery Visualizations - Transforms implicit coroutine suspension and resumption machinery into explicit representations for better understanding.
- C# Compilers - Transforms C++ source code into explicit representations to reveal hidden compiler operations.
- C++ Source-to-Source Translators - Rewrites C++ code to make implicit compiler behaviors and hidden operations explicit and visible.
- Compiler-Integrated AST Parsing - Uses the Clang compiler frontend to parse C++ source code into abstract syntax trees for deep structural inspection.
- Compiler Behavior Visualizations - Translates hidden compiler behaviors like upcasts and generated functions into visible code representations.
- Implicit Compiler Action Expansions - Reveals hidden compiler actions like special member functions and implicit conversions through explicit source transformations.
- C/C++ Static Analysis Tools - Analyzes C++ source code to visualize class hierarchies and expand implicit language constructs.
- Coroutine Operation Expansions - Transforms implicit coroutine machinery into explicit representations to show suspension and resumption handling.
- Template Instantiation Debugging - Reveals the actual code generated during the C++ template instantiation process.
- Compiler Internals Education - Facilitates studying the internal workings of C++ by showing exactly how the compiler transforms high-level syntax.
- Inheritance Visualizers - Generates structural maps of inheritance to visualize the organization and relationships between classes.
- Using Statement Resolutions - Expands using statements that bring functions or members from base classes into the current class scope.
- Structured Binding Expansions - Converts structured binding declarations into equivalent explicit operations to reveal implicit decomposition.
- 调试与追踪 - Shows source code as the compiler sees it.
