C++ Insights is a Clang-based source-to-source transformation tool that shows the compiler's view of C++ code, revealing implicit conversions, compiler-generated special members, lambda desugaring, and auto type deduction. It is available as a CLI tool and an online web interface at cppinsights.io.
Use cases
- see how the compiler transforms my C++ lambdas
- understand what auto deduces to in my code
- show students what a range-based for-loop expands to
- view compiler-generated constructors and operators
- understand implicit casts and upcasts in C++
- learn what structured bindings look like to the compiler
When to choose
- teaching or learning modern C++ internals
- debugging subtle type deduction or implicit conversion behavior
- exploring how C++11/14/17/20 features desugar
When to avoid
- you need actual assembly output (use Compiler Explorer)
- you need a full static analysis or linting tool
- your code uses constructs the tool cannot yet transform
