An embarassingly simple progress bar for C++ loops

progressbar

A very simple, header-only, fully customizable, progress bar (with percentage) for c++ loops.

Very simple to set up:

#include "progressbar.hpp"

int main() {
    progressbar bar(100);
    for (int i = 0; i < 100; ++i) {
        bar.update();
        // ... the program
    }
    return 0;
}

Allows customization:

#include "progressbar.hpp"

int main() {
    progressbar bar(100);
    bar.set_todo_char(" ");
    bar.set_done_char("█");
    bar.set_opening_bracket_char("{");
    bar.set_closing_bracket_char("}");
    for (int i = 0; i < 100; ++i) {
        bar.update();
        // ... the program
    }
    return 0;
}

Notes

To use the bar in parallelized loops call progressbar::update in a critical section. With OpenMP this can be achieved with the following structure:

#pragma omp parallel for
for ( ... ) {
    #pragma omp critical
        bar.update();
}

progressbar's Issues

Support any class which looks like an std::basic_ostream?

It's right now std::cout everywhere. It would be cool that if we could use own classes (e.g. Qt loggers / Boost.log loggers / any another with operator << )

Mutiple definitions when linking

Hi,
I get several multiple definitions errors when trying to link. This happens when I am including your library in different source files. The compilations is flawless, but the linker complains about multiple definitions.
Not a C++ expert here, but I got this fixed by declaring those methods "inline".

See: https://stackoverflow.com/questions/29218714/multiple-definition-of-error-while-writing-a-header-only-template-library

Bar not updating right

The bar is not updating right when the number of iterations is less than 52

Steps to reproduce:

Use the following for loop

progressbar p_bar(29);

for (int i = 0; i < 29; ++i){
    bar.update();

   // Do the work...
}

Expected Output upon completion:

[################################################] 100%

Actual output upon completion:

[   # #      # #    # # #    # #      # #    # ##] 100%

Jupyter notebook

Hello,

is there a way in order to make this nicely compatible with jupyter notebook?

I am calling some C++ functions from jupyter with python and in the terminal the progress bar is displayed nicely, but on the terminal the result is very strange (see pictures).

Is there an "easy" way to solve this?

Thank you and congratulations!

multi-line comment warning

While compiling, I get a multi-line comment warning.

progressbar/progressbar.hpp

Line 26 in 9fcfec7

// |_| |_| \ \_\_/ \_\_/ |_| \ |_|__ _)_) _)_) |_|_) /_/--\ |_| \

I mean, it is not that big of a deal, but it's just not nice to get warnings while compiling. You can add a . in line 26 for example.
