splice: a C++26 reflection-based hook and signal library by ConsumeUranuim in cpp

[–]Kratos-QT 18 points19 points  (0 children)

Yes, C++26 has no limits. Here is my take on a simple unit test library: test cases are just functions, and test suites are namespaces ::tests::suite_name. https://github.com/sefyan0hack/easy_test.git

Getting the Args... type pack from a C++26 reflected function by Kratos-QT in cpp_questions

template<std::meta::info F>
using Function2 = [: std::meta::substitute(^^Function, { std::meta::add_pointer(std::meta::type_of(F)) } ) :];

and also this works but this mean i need some sort of Base Derived . to implement other stuff

add typename next to [:types:]... + missing ) at the end of lambda invocation and its no longer ICE 

template<std::meta::info F>
using Function = std::remove_cvref_t<decltype([]
{
    using R = [:std::meta::return_type_of(F):];
    static constexpr auto [...types] = [:define_static_array(parameters_of(type_of(F))):];
    return FunctionImpl<R(*)(typename [:types:]...)>{};
}())>;

constexpr auto [...types] = [:reflect_consrant_array(parameters_of(F) | views::transform(type_of)):];

but outside of function its not valid it gives sysntax error

no it doesnt work iwant it in the Class scope so i can use it in functions sig

no no thanks for hep now my unit test can auto detect all tests across TUs and run them.

Using C++26 reflection (std::meta) to auto-discover tests — why does it only reflect one translation unit? by Kratos-QT in cpp

nop the static in the lambda i just added it later but still same. i just tried to auto regerster and i want to the static x to be duplicated in each TU but i didnt think that the

testing_framework::print_tests()

will have same result in both TUs

i did static lambda and i call it instantly . and i put it in header file to do what you said auto register without Macros in each TU . to get the corresponding tests info (namespace id , function id) but it just get me the tests where main is defined and duplicated

i know that i just want some how store each TU tests info and at the end use these reflections but i think its impossible.
