Script Sender example

The following example creates a ScriptSender listening on port 12345 and sends the script textmsg("Hello, World!") when requested. A fully compilable example can be found in script_sender.cpp

Listing 33 examples/script_sender.cpp

constexpr uint32_t PORT = 12345;

int main(int argc, char* argv[])
{
  // Parse how may seconds to run
  int second_to_run = -1;
  if (argc > 2)
  {
    second_to_run = std::stoi(argv[2]);
  }
  urcl::control::ScriptSender sender(PORT, "textmsg(\"Hello, World!\")");

  std::stringstream ss;
  ss << "Waiting for incoming requests on port " << PORT;
  if (second_to_run > 0)
  {
    ss << " for " << second_to_run << " seconds";
  }
  else
  {
    ss << " indefinitely";
  }

  std::cout << ss.str() << std::endl;

  const auto start_time = std::chrono::system_clock::now();
  while (second_to_run < 0 || std::chrono::system_clock::now() - start_time < std::chrono::seconds(second_to_run))
  {
    std::this_thread::sleep_for(std::chrono::milliseconds(500));
  }
  std::cout << "Timeout reached" << std::endl;

  return 0;
}
