Hello!
Why does boost::progress_timer write two newlines on destruction?
One would suffice for me.
Another thing about progress_timer: Why is the only option to
output seconds? I'd like to be able to use my own formatter, so
that I can have the output in HH:MM:SS.mmm for example:
boost::progress_timer timer(cout, hhmmssmmm_formatter());
Care to submit a patch?
Here is a patch. With it, it is possible to use progress_timer as such:
#include
#include <iomanip>
using namespace std;
// Time: S.mmm
struct my_formatter
{
string operator()(double s) const
{
stringstream stream;
stream
<< "Time: " << fixed << setprecision(3) << s
<< " s\n"
;
return stream.str();
}
};
// formats as HH:MM:SS.mmm
string form(double s)
{
stringstream stream;
int h = static_cast<int>(s/3600);
int min = static_cast<int>((s-h*3600))/60;
double sec = s - h*3600 - min*60;
stream << setfill('0') << setw(2) << h;
stream << ':';
stream << setfill('0') << setw(2) << min;
stream << ':';
stream << fixed << setprecision(3) << setfill('0') << setw(6) << sec;
stream << '\n';
return stream.str();
}
int main()
{
{
boost::progress_timer t(cout, my_formatter());
}
{
boost::progress_timer t(cout, form);
}
}
Hälsningar,
Daniel
