Description
Currently the --show-progress option is not supported on the windows platform. If I'm not wrong the only reason is the different console type on windows? I wrote some code that should work for all console types. I tested this successful on windows with a dos, cygwin and mingw64 shell.
void ConsoleProgressObserver::eraseCurrentPercentageString()
{
const int charsToErase = m_percentage == 0 ? 2 : m_percentage < 10 ? 3 : 4;
// move cursor left
std::cout << QString(charsToErase, QChar(QLatin1Char('\b'))).toLocal8Bit().constData();
// erase via spaces
std::cout << QString(charsToErase, QChar(QLatin1Char(' '))).toLocal8Bit().constData();
// move cursor left again
std::cout << QString(charsToErase, QChar(QLatin1Char('\b'))).toLocal8Bit().constData();
#if 0
// old implementation
// (1) Move cursor before the old percentage string.
// (2) Erase current line content to the right of the cursor.
std::cout << QString::fromLatin1("\x1b[%1D").arg(charsToErase).toLocal8Bit().constData();
std::cout << "\x1b[K";
#endif
}
