Usage
Source code:
#include <QtArgumentParser>
#include <QCoreApplication>
#include <iostream>
int main(int argc, char **argv)
{
QCoreApplication args(argc, argv);
QtArgumentParser parser(args.arguments());
parser.add("-i", QtArgumentParser::String);
parser.add("-o", QtArgumentParser::String);
parser.add("-n", QtArgumentParser::Integer);
parser.add("-d", QtArgumentParser::Double);
parser.add("-f", QtArgumentParser::Flag);
parser.add("-x", QtArgumentParser::Variant,
QStringList() << "Variant" << "SomeCode" << "Unknow" << "None");
if (!parser.parse())
{
std::cout << "can not parse the arguments" << std::endl;
std::cout << parser.errorString().toStdString() << std::endl;
return -1;
}
QVariantMap map = parser.result();
if (!map.contains("-i") || !map.contains("-o"))
{
std::cout << "arguments \"-i\" and \"-o\" are required" << std::endl;
return -1;
}
std::cout << "The arguments:" << std::endl;
foreach (const QString &key, map.keys())
{
switch (map.value(key).type())
{
case QVariant::String:
std::cout << " " << key.toStdString()
<< " = "<< map.value(key).toString().toStdString()
<< std::endl;
break;
case QVariant::Int:
case QVariant::LongLong:
std::cout << " " << key.toStdString()
<< " = "<< map.value(key).toLongLong()
<< std::endl;
break;
case QVariant::Double:
std::cout << " " << key.toStdString()
<< " = "<< map.value(key).toDouble()
<< std::endl;
break;
case QVariant::Bool:
std::cout << " " << key.toStdString()
<< " = "<< ((map.value(key).toBool())?("true"):("false"))
<< std::endl;
break;
default: ;
}
}
std::cout << "The unused values:" << std::endl;
foreach (const QString &value, parser.unused())

return 0;
