Simple Extractor using QArchive

Please refer the full class documentation here.

This simple example extracts a given archive supported by libarchive. This examples make file expects that QArchive is installed to the system. (or you can also modify it to use add_subdirectory).

main.cpp

#include <QCoreApplication>
#include <QDebug>
#include <QArchive/QArchive>

int main(int ac, char **av)
{
    if(ac < 2) {
        qDebug() << "Usage: " << av[0] << " [ARCHIVE PATH] [DESTINATION PATH]";
        return 0;
    }

    /* include the class from the namespace. */    
    using QArchive::DiskExtractor;

    QCoreApplication app(ac, av);

    /* Get Archive Destination Information. */
    QString ArchivePath = QString(av[1]); 
    QString DestinationPath = QString(av[2]);

    /* Construct DiskExtractor Object. */
    DiskExtractor Extractor(ArchivePath , DestinationPath);
    
    /* Connect Signals with Slots (in this case lambda functions). */
    QObject::connect(&Extractor , &DiskExtractor::finished , [&](){
        qInfo() << "Extracted File(s) Successfully!";
        app.quit();
        return;
    });
    QObject::connect(&Extractor , &DiskExtractor::error ,
    [&](short code){
        qInfo() << "An error has occured ::"
                << QArchive::errorCodeToString(code);
        app.quit();
        return;
    });
    
    Extractor.start();
    return app.exec();
}
