A simple tool to sort and print in a more human readable form the compiler output

main.cpp

#include <QtCore>

static void dump(const char* name, const QStringList& variable) {
    QTextStream out(stdout);
    out << variable.count() << " " << name << endl;
    foreach (const QString& item, variable) {
        out << "  " << item << endl;
    }
}

int main(int argc, char* argv[])
{
    QCoreApplication application(argc, argv);

    QStringList defines;
    QStringList libraries;
    QStringList libraryPaths;
    QStringList includes;
    QStringList objects;

    foreach (const QString& element, application.arguments()) {
        if (element.startsWith("-D"))
            defines << element;
        if (element.startsWith("-l"))
            libraries << element;
        if (element.startsWith("-L"))
            libraryPaths << element;
        if (element.startsWith("-I"))
            includes << element;
        if (element.endsWith(".o"))
            objects << element;
    }

    qSort(defines);
    qSort(libraries);
    qSort(libraryPaths);
    qSort(includes);
    qSort(objects);

    dump("defines", defines);
    dump("libraries", libraries);
    dump("library paths", libraryPaths);
    dump("includes", includes);
    dump("objects", objects);

    return 0;
}

Just a quick paste. The code is old, and I did not bother to fix the usage of deprecated qSort, or port to range-for instead of foreach.
