Customizing Compilation Error Messages Using C++ Concepts

on YouTube ↗05m

" summary

Uses C++20 named concepts plus a static reflection library to turn misspelled member-name errors into actionable suggestions by doing compile-time string processing. Implements a pull request that formats the failing string literal into “did you mean …” output and relies on substitution failure (SFINAE) rather than hard static_asserts so overload resolution can produce suggestions for multiple candidate types. Demonstration builds and prints correct suggested fixes for each overload.
