The Fancy Named Parameters Library

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.

A Short Example

#include <raberu/raberu.hpp>
#include <iostream>
#include <string>
 
using namespace rbr::literals;
 
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()
{
  std::cout << replicate("replication"_kw = 9, "letter"_kw = 'z'   ) << "\n";
  std::cout << replicate("letter"_kw = '!'   , "replication"_kw = 3) << "\n";
}
