Global Functions

std::string mrpt::system::progress(
    const double progressRatio0to1,
    const std::size_t barLength,
    bool encloseInSquareBrackets = true
    )

Build an text incremental progress bar with UNICODE block elements, for example:

50%  => "[████    ]"

See example: system_progress_bar/test.cpp

#include <mrpt/core/exceptions.h>
#include <mrpt/system/progress.h>

#include <chrono>
#include <iostream>
#include <thread>

void TestProgressBar()
{
    const int end = 400;
    const size_t barWidth = 30;

    for (int i = 0; i <= end; i++)
    {
        double p = double(i) / end;

        std::cout << "Progress: " << mrpt::system::progress(p, barWidth)
                  << mrpt::format(" %5.02f%%", 100 * p) << "\r";
        std::cout.flush();
        std::this_thread::sleep_for(std::chrono::milliseconds(5));
    }
    std::cout << std::endl;
}
