runtime::invoke functions with void return type #68 (thanks @ohanar)trait::get_t - speeds up compilation for large classes #72, see discussion in #71refl::util::filter() and its users #65 (thanks @RalphSteinhagen)for_each and (has|get)_(reader|writer) c197d35 and #60get_display_name_const on MSVC #53 (thanks @rpatters1)NOTE: This version does not contain any breaking changes at the source level (as is clear by the patch version increment). However, this version adds CMake support and this required the
refl.hppsource file to be moved to a standard locationinclude/refl.hpp. If you are consuming refl-cpp as a single-header library, you can continue to do so.

Suggested workaround: use predicate variantsrefl::descriptor::get_bases for clang #19refl::descriptor::get_bases (as well as refl::descriptor::has_bases) to inspect a type's declared base types (see example-inheritance.cpp)refl::descriptor::get_property_info to refl::descriptor::get_property to match the attribute name and its trait-based counterparts.std::tuple<...> were sometimes cv-qualified).refl::descriptor::get_display_name() in some compilers (thanks to ticelo)[[maybe_unused]] that caused warnings under clang.refl::const_string<N> instances from const char* which allows using c-strings (const char*) values from attributes together with const_string<N> and in constexpr context possible. That feature is exposed by the REFL_MAKE_CONST_STRING(CString) macro. Important: CString must be a Core constant expression. The macro is necessary to avoid the duplication of the provided expression and currently expands to ~ detail::copy_from_unsized<detail::strlen(CString)>(CString). (another thanks to Siapran for contributing the implementation for the constexpr length() function.)constexpr const_string::substr<Pos, [Count]>()make_const_string() as a shortcut for the creation of empty const strings.trait::{first, last, tail, init, append, prepend, reverse, concat} and TraitName_t equivalents to ease the use of type_list<...>.trait::map and trait::filter now no longer accept variadic template parameters. Wrap variadic parameters in a type_list. (Allowing both type_list<Ts...> and Ts... is problematic due to cryptic errors when e.g. const type_list<Ts...> is provided.)util::accumulate now mimics the behaviour of std::accumulate more closely. It relies on the return value of the functor instead of mutating the accumulator argument. The new implementation now allows for the types of initial_value and the return type to differ (thanks to Siapran).util::get<N>(const type_list<Ts...>&). Use trait::get_t<N, type_list<Ts...>> instead. This is part of a move towards minimizing the duplication between the trait:: and util:: namespaces.operator+(const_string<N>, const_string<M>) (fixed by Siapran) #11type_descriptor<T>::type as an alias for T.function_descriptor<T, N>::pointer which points to the target function, if the pointer can be resolved and to nullptr otherwise.function_descriptor<T, N>::is_resolved for checking whether the pointer to the function has been resolved successfully.function_descriptor<T, N>::resolve<Pointer> for explicitly resolving the function pointer as a value of the specified type.util::get<size_t N>(type_list<Ts...>&&) which zero-initializes and returns the type at the N-th position.util::get<size_t N>(Tuple&&) as an alias for std::get<N>.$refl(...), REFL_UNSTABLE(...), REFL_DEPRECATED(...)refl::attr::access_type::read, write constants.

(Reason: Replacing with forwarding function allows for more flexibility when using refl::runtime::proxy<>. Migrate by taking a pointer to function_descriptor<...>invoke())std::tuple<...> or support variadic arguments. Use type_list<> or trait::as_type_list_t to migrate working code. (Reason: Specializations found to be causative to many recently discovered bugs and are error-prone.)trait::skip<N>util::to_tupletrait::contains_base was working the other way around (checking for presense of base of a specified type, instead of checking for a derived type with a specified base)type_info__<T*> has name defined as char[N] instead of const_string<N>REFL_NO_VARIADICS) refl::util::const_string<N> can now be directly compared for equality with char[M]refl::util::const_string<N> can now be concatenated with char[M]refl::runtime::debug now captures values of member invocations by universal references (previous implementations required a copy of the value)refl::runtime::debug now does not require the members of composites to be reflectable.
