• you can now use CTRE as C++ module! with -DCTRE_MODULE=ON (experimental) 🎉
• ctre::range is deprecated and replaced with ctre::search_all

void print_all_string(std::string_view subject) {
  for (auto word: ctre::search_all<"\\w+">(subject)) {
    std::cout << word.to_view() << "\n";
  }
}

• simple ctre::capture_group concept
• capture groups / result type now has .to_optional_number(...) member function which returns std::nullopt if group is not matching

  return ctre::match<"([0-9]+)">(subject).to_optional_number();
}
