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("β");
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();
}
