struct ChildProcess
{
  ChildProcess(
    const std::filesystem::path& executablePath,
    std::span<const string_view> arguments,
    std::function<void(int)>&& onKilled // called if process dies, gets return code
  );

  // appends final \n when sending to process stdin
  void write_line(string_view);

  // non-blocking, returns immediately
  std::future<std::string> read_line();
};
