Easily Create Progress Bars in C

c_progress_bar is a library for C that helps you create:

Colorful progress bar
Estimated remaining time
Elapsed time tracking
Works with MSVC, Clang, and GCC
Written in C99 with minimal dependencies

Installation

git clone https://github.com/c-modules/c_progress_bar
cd c_progress_bar/
cmake . -B build
cmake --build build/
sudo cmake install build

Simple example

#include <stdint.h>
#include <stdio.h>
#include <stdlib.h>

#include "c_progress_bar.h"

#define N 1000000000

int main(void)
{
    double sum = 0.0;

    // Setup progress bar
    CPB_Config config = cpb_get_default_config();
    config.description = "Processing";                // Default: ""
    config.min_refresh_time = 0.1;                    // Minimum refresh time in seconds. Default: 0.1.
    config.timer_remaining_time_recent_weight = 0.3;  // Weight for recent rate in remaining time estimation. Range: [0, 1]. Default: 0.3.

    // You don't need to modify anything for CPB_ProgressBar.
    // Just call cpb_init
    CPB_ProgressBar progress_bar;
    cpb_init(&progress_bar, 0, N, config);

    // Main loop
    cpb_start(&progress_bar);
    for (int64_t i = 0; i <= N; i++)
    {
        if (i % 1000 == 0)
        {
            cpb_update(&progress_bar, i);
        }

        sum += (i % 100) * 0.0001;
    }
    cpb_finish(&progress_bar);

    printf("Final result: %f\n", sum);

    return 0;
}
