Keynote: Not Getting Lost in Translations in C++ Software Development
summary
Claims ability to keep compile-time validation of std::format-style format strings while allowing runtime language selection; implements a pipeline that extracts translatable literals, compiles gettext PO/message-format into constexpr tables, and uses consteval/constexpr, C++20/23/26 features (including heterogenous type indexing and reflection) to validate formats, plural forms (from Unicode rules) and argument-to-quantity mapping at compile time. Integrates with build tools, replaces boost::locale backend, runs the same checks at runtime and compile time and reports mismatches before deployment.
