RABERU provides a way to define and use named parameters, i.e a list of values assigned to arbitrary keyword-like identifiers, to functions.
It does so by providing:
- a protocol to define such keywords.
- a type to process such aggregate of parameters.
- a
constexpr-compatible implementation for all of those.

#include <raberu/raberu.hpp>
#include <iostream>
#include <string>
template<rbr::concepts::option P0, rbr::concepts::option P1>
auto replicate( P0 p0, P1 p1 )
{
auto const params = rbr::settings(p0,p1);
return std::string( params["replication"_kw], params["letter"_kw] );
}
int main()
{
using namespace rbr::literals;
std::cout << replicate("replication"_kw = 9, "letter"_kw = 'z' ) << "\n";
std::cout << replicate("letter"_kw = '!' , "replication"_kw = 3) << "\n";
