C++ Insights transforms source code to expose compiler-generated constructs

github.com 6 min read Editor score 7/10

The Clang-based tool rewrites C++ to show constructs such as defaulted constructors, assignment operators and casts that the compiler supplies. It can help engineers inspect language behavior that is otherwise implicit.

What: C++ Insights is a Clang-based source-to-source tool that makes compiler-generated constructs visible in transformed code.
How: It exposes special member functions, casts, operator calls, and inferred types such as auto or decltype.
Why it matters: Seeing transformations in C++ rather than an AST or assembly can help engineers understand how compiler behavior affects their code.

C++ Insights transforms a source snippet into code that exposes compiler-generated constructs. Sketched from the article's own text.
