Outputting text above user input with cout in separate thread
I'm running two threads in a program. One thread sends seconds elapsed to cout every second and the other thread runs a while loop that uses getline and cin to get input from the user in a sort of shell or command line.
My issue is that whenever something is sent to cout while the user is typing something it ends up on top of whatever the user has just typed and it ends up looking messy like this.
Is there any way to move what the user is typing a line down whenever something is sent to cout? Or maybe some alternative io that does this?
I would rather the output look more like this
Here's some extra details and some code:
#include <boost/algorithm/string.hpp>
#include <iostream>
#include <sstream>
#include <thread>
#include <chrono>
#include <vector>
using std::thread;
using std::vector;
using std::string;
using std::cout;
using std::cin;
void loop(bool &running)
{
int secondsElapsed = 0;
while (running)
{
std::this_thread::sleep_for(std::chrono::milliseconds(1000));
secondsElapsed++;
cout << std::to_string(secondsPassed) << " Seconds Passedn";
}
}
int main()
{
//STARTING OTHER THREAD RIGHT AWAY
bool running = true;
std::thread t(loop, std::ref(running));
string param;
string currentLine;
vector<string> params;
while (true)
{
//PARSING USER INPUT FOR EVALUATION
params.clear();
getline(cin, currentLine);
std::stringstream currentLineStream(currentLine);
//CHECKING SIZE OF USER INPUT TO SEE IF THERE IS ANY
if (currentLineStream.rdbuf()->in_avail() > 0)
{
while (getline(currentLineStream, param, ' '))
{
params.push_back(param);
}
//CAPITALISING FIRST PARAMETER TO MAKE EVALUATION EASIER
boost::to_upper(params[0]);
}
else
{
params.push_back("");
}
//FINISHED PARSING INPUT, EVALUATING
if (params[0] == "STOP")
{
running = false;
break;
}
else
{
cout << "Unknown Command, help menu not implemented yet sorryn";
}
} //END OF USER INPUT LOOP
t.join(); //WAITING FOR OTHER THREAD TO FINISH
return 0;
}
