catch3/tests/Progmasoft/Snapshot.tests.cpp, branch devel Progmasoft Catch3: an independently maintained C++17 test framework with a parallel runner, property checks, snapshots and structured results. Move to the Progmasoft Linking Exception, Version 2.0 2026-10-31T10:42:35+00:00 Leitwolf11 2026-10-31T10:42:35+00:00 31486e3217b8424809bcf129c0ef24ef5639e919 Version 1.1 left programs built with Progmasoft tools under MPL-2.0 duties for the code the tools place in them, and left other cases unclear. Version 2.0 adds a generated code permission, covers runtime and standard libraries, compiler transformations, interfaces and examples, and settles how a file is identified and how to tell recipients about source. Every project SPDX expression moves to AdditionRef-Progmasoft-Exception-2.0. The older texts stay, because released versions name them.

Build Catch3 as C++17 2026-10-31T10:00:24+00:00 Leitwolf11 2026-10-31T10:00:24+00:00 8814bd0b796b2e291fa5b4a1033f0313c8a26065 C++17 is still the widest common target, and a library built on it stays usable from C++17 and every later standard, while C++20 would have left out many users. Concepts become enable_if on named traits in Detail/TypeTraits.hpp, which also replaces std::remove_cvref_t and std::identity. std::span becomes std::vector references, std::bit_cast becomes static_cast and memcpy, template lambdas become helper templates, and std::erase_if, contains, starts_with and ends_with have their C++17 forms. Random::Between no longer uses a lambda over a constexpr local, which MSVC rejects outside /permissive-, so the headers work under its default mode too. Tests give up designated initializers, which MSVC refuses in C++17. CI builds the matrix in C++17 and C++20, since the headers promise both.
