Basic Progress bar

To introduce a progress bar in your application, include indicators/progress_bar.hpp and create a ProgressBar object. Here's the general structure of a progress bar:

{prefix} {start} {fill} {lead} {remaining} {end} {percentage} [{elapsed}<{remaining}] {postfix}
         ^^^^^^^^^^^^^ Bar Width ^^^^^^^^^^^^^^^   

The amount of progress in ProgressBar is maintained as a size_t in range [0, 100]. When progress reaches 100, the progression is complete.

From application-level code, there are two ways in which you can update this progress:

Update progress using bar.tick()

You can update the progress bar using bar.tick() which increments progress by exactly 1%.

#include <indicators/progress_bar.hpp>
#include <thread>
#include <chrono>

int main() {
  using namespace indicators;
  ProgressBar bar{
    option::BarWidth{50},
    option::Start{"["},
    option::Fill{"="},
    option::Lead{">"},
    option::Remainder{" "},
    option::End{"]"},
    option::PostfixText{"Extracting Archive"},
    option::ForegroundColor{Color::green},
    option::FontStyles{std::vector<FontStyle>{FontStyle::bold}}
  };
  
  // Update bar state
  while (true) {
    bar.tick();
    if (bar.is_completed())
      break;
    std::this_thread::sleep_for(std::chrono::milliseconds(100));
  }

  return 0;
}

The above code will print a progress bar that goes from 0 to 100% at the rate of 1% every 100 ms.

Updating progress using bar.set_progress(value)

If you'd rather control progress of the bar in discrete steps, consider using bar.set_progress(value). Example:

#include <chrono>
#include <indicators/cursor_control.hpp>
#include <indicators/progress_bar.hpp>
#include <thread>

int main() {
  using namespace indicators;

  // Hide cursor
  show_console_cursor(false);

  ProgressBar bar{
    option::BarWidth{50},
    option::Start{"["},
    option::Fill{"β– "},
    option::Lead{"β– "},
    option::Remainder{"-"},
    option::End{" ]"},
    option::PostfixText{"Loading dependency 1/4"},
    option::ForegroundColor{Color::cyan},
    option::FontStyles{std::vector<FontStyle>{FontStyle::bold}}
  };

  // Update bar state
  bar.set_progress(10); // 10% done

  // do some work
  std::this_thread::sleep_for(std::chrono::milliseconds(800));

  bar.set_option(option::PostfixText{"Loading dependency 2/4"});  

  bar.set_progress(30); // 30% done

  // do some more work
  std::this_thread::sleep_for(std::chrono::milliseconds(700));

  bar.set_option(option::PostfixText{"Loading dependency 3/4"});  

  bar.set_progress(65); // 65% done

  // do final bit of work
  std::this_thread::sleep_for(std::chrono::milliseconds(900));

  bar.set_option(option::PostfixText{"Loaded dependencies!"});

  bar.set_progress(100); // all done

  // Show cursor
  show_console_cursor(true);

  return 0;
}

Showing Time Elapsed/Remaining

All progress bars and spinners in indicators support showing time elapsed and time remaining. Inspired by python's tqdm module, the format of this meter is [{elapsed}<{remaining}]:

#include <chrono>
#include <indicators/cursor_control.hpp>
#include <indicators/progress_bar.hpp>
#include <thread>

int main() {
  using namespace indicators;

  // Hide cursor
  show_console_cursor(false);

  indicators::ProgressBar bar{
    option::BarWidth{50},
    option::Start{" ["},
    option::Fill{"β–ˆ"},
    option::Lead{"β–ˆ"},
    option::Remainder{"-"},
    option::End{"]"},
    option::PrefixText{"Training Gaze Network πŸ‘€"},
    option::ForegroundColor{Color::yellow},
    option::ShowElapsedTime{true},
    option::ShowRemainingTime{true},
    option::FontStyles{std::vector<FontStyle>{FontStyle::bold}}
  };

  // Update bar state
  while (true) {
    bar.tick();
    if (bar.is_completed())
      break;
    std::this_thread::sleep_for(std::chrono::milliseconds(1000));
  }

  // Show cursor
  show_console_cursor(true);

  return 0;
}

Indeterminate Progress Bar

You might have a use-case for a progress bar where the maximum amount of progress is unknown, e.g., you're downloading from a remote server that isn't advertising the total bytes.

Use an indicators::IndeterminateProgressBar for such cases. An IndeterminateProgressBar is similar to a regular progress bar except the total amount to progress towards is unknown. Ticking on this progress bar will happily run forever.

When you know progress is complete, simply call bar.mark_as_completed().

#include <chrono>
#include <indicators/indeterminate_progress_bar.hpp>
#include <indicators/cursor_control.hpp>
#include <indicators/termcolor.hpp>
#include <thread>

int main() {
  indicators::IndeterminateProgressBar bar{
      indicators::option::BarWidth{40},
      indicators::option::Start{"["},
      indicators::option::Fill{"Β·"},
      indicators::option::Lead{"<==>"},
      indicators::option::End{"]"},
      indicators::option::PostfixText{"Checking for Updates"},
      indicators::option::ForegroundColor{indicators::Color::yellow},
      indicators::option::FontStyles{
          std::vector<indicators::FontStyle>{indicators::FontStyle::bold}}
  };

  indicators::show_console_cursor(false);

  auto job = [&bar]() {
    std::this_thread::sleep_for(std::chrono::milliseconds(10000));
    bar.mark_as_completed();
    std::cout << termcolor::bold << termcolor::green 
        << "System is up to date!\n" << termcolor::reset;
  };
  std::thread job_completion_thread(job);

  // Update bar state
  while (!bar.is_completed()) {
    bar.tick();
    std::this_thread::sleep_for(std::chrono::milliseconds(100));
  }

  job_completion_thread.join();
  
  indicators::show_console_cursor(true);  
  return 0;
}

Block Progress Bar

Are you in need of a smooth block progress bar using unicode block elements? Use BlockProgressBar instead of ProgressBar. Thanks to this blog post for making BlockProgressBar an easy addition to the library.

#include <indicators/block_progress_bar.hpp>
#include <indicators/cursor_control.hpp>
#include <thread>
#include <chrono>

int main() {

  using namespace indicators;

  // Hide cursor
  show_console_cursor(false);

  BlockProgressBar bar{
    option::BarWidth{80},
    option::Start{"["},
    option::End{"]"},
    option::ForegroundColor{Color::white}  ,
    option::FontStyles{std::vector<FontStyle>{FontStyle::bold}}
  };
  
  // Update bar state
  auto progress = 0.0f;
  while (true) {
    bar.set_progress(progress);
    progress += 0.25f;
    if (bar.is_completed())
      break;
    std::this_thread::sleep_for(std::chrono::milliseconds(50));
  }

  // Show cursor
  show_console_cursor(true);

  return 0;
}

MultiProgress

indicators supports management of multiple progress bars with the MultiProgress class template.

template <typename Indicator, size_t count> class MultiProgress is a class template that holds references to multiple progress bars and provides a safe interface to update the state of each bar. MultiProgress works with both ProgressBar and BlockProgressBar classes.

Use this class if you know the number of progress bars to manage at compile time.

Below is an example MultiProgress object that manages three ProgressBar objects.

#include <indicators/multi_progress.hpp>
#include <indicators/progress_bar.hpp>

int main() {
  using namespace indicators;
  // Configure first progress bar
  ProgressBar bar1{
    option::BarWidth{50},
    option::Start{"["},
    option::Fill{"β– "},
    option::Lead{"β– "},
    option::Remainder{" "},
    option::End{" ]"},
    option::ForegroundColor{Color::yellow},
    option::ShowElapsedTime{true},
    option::ShowRemainingTime{true},
    option::PrefixText{"Progress Bar #1 "},
    option::FontStyles{std::vector<FontStyle>{FontStyle::bold}}
  };

  // Configure second progress bar

  ProgressBar bar2{
    option::BarWidth{50},
    option::Start{"["},
    option::Fill{"="},
    option::Lead{">"},
    option::Remainder{" "},
    option::End{" ]"},
    option::ForegroundColor{Color::cyan},
    option::ShowElapsedTime{true},
    option::ShowRemainingTime{true},
    option::PrefixText{"Progress Bar #2 "},
    option::FontStyles{std::vector<FontStyle>{FontStyle::bold}}
  };
  
  // Configure third progress bar
  indicators::ProgressBar bar3{
    option::BarWidth{50},
    option::Start{"["},
    option::Fill{"#"},
    option::Lead{"#"},
    option::Remainder{" "},
    option::End{" ]"},
    option::ForegroundColor{Color::red},
    option::ShowElapsedTime{true},
    option::ShowRemainingTime{true},
    option::PrefixText{"Progress Bar #3 "},
    option::FontStyles{std::vector<FontStyle>{FontStyle::bold}}
  };

  // Construct MultiProgress object
  indicators::MultiProgress<indicators::ProgressBar, 3> bars(bar1, bar2, bar3);

  std::cout << "Multiple Progress Bars:\n";

  auto job1 = [&bars]() {
    while (true) {
      bars.tick<0>();
      if (bars.is_completed<0>())
        break;
      std::this_thread::sleep_for(std::chrono::milliseconds(100));
    }
  };

  auto job2 = [&bars]() {
    while (true) {
      bars.tick<1>();
      if (bars.is_completed<1>())
        break;
      std::this_thread::sleep_for(std::chrono::milliseconds(200));
    }
  };

  auto job3 = [&bars]() {
    while (true) {
      bars.tick<2>();
      if (bars.is_completed<2>())
        break;
      std::this_thread::sleep_for(std::chrono::milliseconds(60));
    }
  };

  std::thread first_job(job1);
  std::thread second_job(job2);
  std::thread third_job(job3);

  first_job.join();
  second_job.join();
  third_job.join();

  return 0;
}

DynamicProgress

DynamicProgress is a container class, similar to MultiProgress, for managing multiple progress bars. As the name suggests, with DynamicProgress, you can dynamically add new progress bars.

To add new progress bars, call bars.push_back(new_bar). This call will return the index of the appended bar. You can then refer to this bar with the indexing operator, e.g., bars[4].set_progress(55).

Use this class if you don't know the number of progress bars at compile time.

Below is an example DynamicProgress object that manages six ProgressBar objects. Three of these bars are added dynamically.

#include <indicators/dynamic_progress.hpp>
#include <indicators/progress_bar.hpp>
using namespace indicators;

int main() {

  ProgressBar bar1{option::BarWidth{50}, option::ForegroundColor{Color::red},
                   option::ShowElapsedTime{true}, option::ShowRemainingTime{true},
                   option::PrefixText{"5c90d4a2d1a8: Downloading "}};

  ProgressBar bar2{option::BarWidth{50}, option::ForegroundColor{Color::yellow},
                   option::ShowElapsedTime{true}, option::ShowRemainingTime{true},
                   option::PrefixText{"22337bfd13a9: Downloading "}};

  ProgressBar bar3{option::BarWidth{50}, option::ForegroundColor{Color::green},
                   option::ShowElapsedTime{true}, option::ShowRemainingTime{true},
                   option::PrefixText{"10f26c680a34: Downloading "}};

  ProgressBar bar4{option::BarWidth{50}, option::ForegroundColor{Color::white},
                   option::ShowElapsedTime{true}, option::ShowRemainingTime{true},
                   option::PrefixText{"6364e0d7a283: Downloading "}};

  ProgressBar bar5{option::BarWidth{50}, option::ForegroundColor{Color::blue},
                   option::ShowElapsedTime{true}, option::ShowRemainingTime{true},
                   option::PrefixText{"ff1356ba118b: Downloading "}};

  ProgressBar bar6{option::BarWidth{50}, option::ForegroundColor{Color::cyan},
                   option::ShowElapsedTime{true}, option::ShowRemainingTime{true},
                   option::PrefixText{"5a17453338b4: Downloading "}};

  std::cout << termcolor::bold << termcolor::white << "Pulling image foo:bar/baz\n";

  // Construct with 3 progress bars. We'll add 3 more at a later point
  DynamicProgress<ProgressBar> bars(bar1, bar2, bar3);
  
  // Do not hide bars when completed
  bars.set_option(option::HideBarWhenComplete{false});

  std::thread fourth_job, fifth_job, sixth_job;

  auto job4 = [&bars](size_t i) {
    while (true) {
      bars[i].tick();
      if (bars[i].is_completed()) {
        bars[i].set_option(option::PrefixText{"6364e0d7a283: Pull complete "});
        bars[i].mark_as_completed();
        break;
      }
      std::this_thread::sleep_for(std::chrono::milliseconds(50));
    }
  };

  auto job5 = [&bars](size_t i) {
    while (true) {
      bars[i].tick();
      if (bars[i].is_completed()) {
        bars[i].set_option(option::PrefixText{"ff1356ba118b: Pull complete "});
        bars[i].mark_as_completed();
        break;
      }
      std::this_thread::sleep_for(std::chrono::milliseconds(100));
    }
  };

  auto job6 = [&bars](size_t i) {
    while (true) {
      bars[i].tick();
      if (bars[i].is_completed()) {
        bars[i].set_option(option::PrefixText{"5a17453338b4: Pull complete "});
        bars[i].mark_as_completed();
        break;
      }
      std::this_thread::sleep_for(std::chrono::milliseconds(40));
    }
  };

  auto job1 = [&bars, &bar6, &sixth_job, &job6]() {
    while (true) {
      bars[0].tick();
      if (bars[0].is_completed()) {
        bars[0].set_option(option::PrefixText{"5c90d4a2d1a8: Pull complete "});
        // bar1 is completed, adding bar6
        auto i = bars.push_back(bar6);
        sixth_job = std::thread(job6, i);
        sixth_job.join();
        break;
      }
      std::this_thread::sleep_for(std::chrono::milliseconds(140));
    }
  };

  auto job2 = [&bars, &bar5, &fifth_job, &job5]() {
    while (true) {
      bars[1].tick();
      if (bars[1].is_completed()) {
        bars[1].set_option(option::PrefixText{"22337bfd13a9: Pull complete "});
        // bar2 is completed, adding bar5
        auto i = bars.push_back(bar5);
        fifth_job = std::thread(job5, i);
        fifth_job.join();
        break;
      }
      std::this_thread::sleep_for(std::chrono::milliseconds(25));
    }
  };

  auto job3 = [&bars, &bar4, &fourth_job, &job4]() {
    while (true) {
      bars[2].tick();
      if (bars[2].is_completed()) {
        bars[2].set_option(option::PrefixText{"10f26c680a34: Pull complete "});
        // bar3 is completed, adding bar4
        auto i = bars.push_back(bar4);
        fourth_job = std::thread(job4, i);
        fourth_job.join();
        break;
      }
      std::this_thread::sleep_for(std::chrono::milliseconds(50));
    }
  };

  std::thread first_job(job1);
  std::thread second_job(job2);
  std::thread third_job(job3);

  third_job.join();
  second_job.join();
  first_job.join();

  std::cout << termcolor::bold << termcolor::green << "βœ” Downloaded image foo/bar:baz" << std::endl;
  std::cout << termcolor::reset;

  return 0;
}

In the above code, notice the option bars.set_option(option::HideBarWhenComplete{true});. Yes, you can hide progress bars as and when they complete by setting this option to true. If you do so, the above example will look like this:

Progress Spinner

To introduce a progress spinner in your application, include indicators/progress_spinner.hpp and create a ProgressSpinner object. Here's the general structure of a progress spinner:

{prefix} {spinner} {percentage} [{elapsed}<{remaining}] {postfix}

ProgressSpinner has a vector of strings: spinner_states. At each update, the spinner will pick the next string from this sequence to print to the console. The spinner state can be updated similarly to ProgressBars: Using either tick() or set_progress(value).

#include <indicators/progress_spinner.hpp>

int main() {
  using namespace indicators;
  indicators::ProgressSpinner spinner{
    option::PostfixText{"Checking credentials"},
    option::ForegroundColor{Color::yellow},
    option::SpinnerStates{std::vector<std::string>{"⠈", "⠐", "β  ", "β’€", "β‘€", "β „", "β ‚", "⠁"}},
    option::FontStyles{std::vector<FontStyle>{FontStyle::bold}}
  };
 
  // Update spinner state
  auto job = [&spinner]() {
    while (true) {
      if (spinner.is_completed()) {
        spinner.set_option(option::ForegroundColor{Color::green});
        spinner.set_option(option::PrefixText{"βœ”"});
        spinner.set_option(option::ShowSpinner{false});
        spinner.set_option(option::ShowPercentage{false});
        spinner.set_option(option::PostfixText{"Authenticated!"});
        spinner.mark_as_completed();	
        break;
      } else
        spinner.tick();
      std::this_thread::sleep_for(std::chrono::milliseconds(40));
    }
  };
  std::thread thread(job);
  thread.join();  

  return 0;
}

Decremental Progress

indicators allows you to easily control the progress direction, i.e., incremental or decremental progress by using option::ProgressType. To program a countdown progress bar, use option::ProgressType::decremental

#include <chrono>
#include <indicators/progress_bar.hpp>
#include <thread>
using namespace indicators;

int main() {

  ProgressBar bar{option::BarWidth{50},
                  option::ProgressType{ProgressType::decremental},
                  option::Start{"["},
                  option::Fill{"β– "},
                  option::Lead{"β– "},
                  option::Remainder{"-"},
                  option::End{"]"},
                  option::PostfixText{"Reverting System Restore"},
                  option::ForegroundColor{Color::yellow},
                  option::FontStyles{std::vector<FontStyle>{FontStyle::bold}}};

  // Update bar state
  while (true) {
    bar.tick();
    if (bar.is_completed())
      break;
    std::this_thread::sleep_for(std::chrono::milliseconds(100));
  }

  std::cout << termcolor::bold << termcolor::white
            << "Task Failed Successfully\n" << termcolor::reset;

  return 0;
}

Working with Iterables

If you'd like to use progress bars to indicate progress while iterating over iterables, e.g., a list of numbers, this can be achieved by using the option::MaxProgress:

#include <chrono>
#include <indicators/block_progress_bar.hpp>
#include <indicators/cursor_control.hpp>
#include <thread>

int main() {

  // Hide cursor
  indicators::show_console_cursor(false);

  // Random list of numbers
  std::vector<size_t> numbers;
  for (size_t i = 0; i < 1259438; ++i) {
      numbers.push_back(i);
  }

  using namespace indicators;
  BlockProgressBar bar{
    option::BarWidth{80},
    option::ForegroundColor{Color::white},
    option::FontStyles{
          std::vector<FontStyle>{FontStyle::bold}},
    option::MaxProgress{numbers.size()}
  };

  std::cout << "Iterating over a list of numbers (size = "
            << numbers.size() << ")\n";

  std::vector<size_t> result;
  for (size_t i = 0; i < numbers.size(); ++i) {

    // Perform some computation
    result.push_back(numbers[i] * numbers[i]);

    // Show iteration as postfix text
    bar.set_option(option::PostfixText{
      std::to_string(i) + "/" + std::to_string(numbers.size())
    });

    // update progress bar
    bar.tick();
  }

  bar.mark_as_completed();

  // Show cursor
  indicators::show_console_cursor(true);

  return 0;
}

Unicode Support

indicators supports multi-byte unicode characters in progress bars.

If the option::BarWidth is set, the library aims to respect this setting. When filling the bar, if the next Fill string has a display width that would exceed the bar width, then the library will fill the remainder of the bar with ' ' space characters instead.

See below an example of some progress bars, each with a bar width of 50, displaying different unicode characters:

#include <chrono>
#include <indicators/progress_bar.hpp>
#include <indicators/indeterminate_progress_bar.hpp>
#include <indicators/cursor_control.hpp>
#include <thread>

int main() {

    indicators::show_console_cursor(false);

    std::this_thread::sleep_for(std::chrono::milliseconds(2000));

    {
        // Plain old ASCII
        indicators::ProgressBar bar{
            indicators::option::BarWidth{50},
            indicators::option::Start{"["},
            indicators::option::Fill{"="},
            indicators::option::Lead{">"},
            indicators::option::Remainder{" "},
            indicators::option::End{" ]"},
            indicators::option::PostfixText{"Plain-old ASCII"},
            indicators::option::ForegroundColor{indicators::Color::green},
            indicators::option::FontStyles{
                std::vector<indicators::FontStyle>{indicators::FontStyle::bold}}
        };

        // Update bar state
        while (true) {
            bar.tick();
            if (bar.is_completed())
            break;
            std::this_thread::sleep_for(std::chrono::milliseconds(10));
        }
    }

    {
        // Unicode
        indicators::ProgressBar bar{
            indicators::option::BarWidth{50},
            indicators::option::Start{"["},
            indicators::option::Fill{"ι©šγγ°γ‹γ‚Š"},
            indicators::option::Lead{">"},
            indicators::option::Remainder{" "},
            indicators::option::End{" ]"},
            indicators::option::PostfixText{"Japanese"},

cd indicators
mkdir build && cd build
cmake -DINDICATORS_SAMPLES=ON -DINDICATORS_DEMO=ON ..
make

WinLibs + MinGW

For Windows, if you use WinLibs like I do, the cmake command would look like this:

foo@bar:~$ mkdir build && cd build
foo@bar:~$ cmake -G "MinGW Makefiles" -DCMAKE_CXX_COMPILER="C:/WinLibs/mingw64/bin/g++.exe" -DINDICATORS_SAMPLES=ON -DINDICATORS_DEMO=ON ..
foo@bar:~$ make -j4
