Log library for Qt 5 or 6 (based on SLogLib) :kr: Qt 5 또는 6 기반 로그 라이브러리

QSLogLib

Read this in other languages: English, 🇰🇷 한국어

• QSLogLib is a log library based on SLogLibs.
• It is ported to Qt with improved devices and function.

Note

• Cmake is not any more supported.
• Use Qt. instead of complicated cross-platform code.
• UDP client logger has been added.
• Other devices will be added. (RDBMS, NoSQL, Bletooth, Serial, DDS, MQ, etc)

Example

1️⃣ How to setup

• First, include pri file on your Qt project file(*.pro).

# Define QSLogLib relative path. You can fix this directory
#   QSLOG_PARENTPATH = ../../
#   QSLOG_HEADERPATH = ../../QSLogLib/
#   QSLOG_SOURCEPATH = ../../QSLogLib/
include(../../QSLogLib/QSLogLib.pri)

2️⃣ Logging Example for standard output and file

#include <QtGlobal>
#include <QCoreApplication>

#include "QSLogLib/SLogLib.h"
#include "QSLogLib/Devices/AbstractLoggingDevice.h"
#include "QSLogLib/Devices/ConsoleLogger.h"
#include "QSLogLib/Devices/FileLogger.h"
#include "QSLogLib/Devices/UdpLogger.h"
#include "QSLogLib/Formatters/AbstractFormatter.h"
#include "QSLogLib/Formatters/DetailedFormatter.h"
#include "QSLogLib/Formatters/ErrorFormatter.h"
#include "QSLogLib/Formatters/InfoFormatter.h"
#include "QSLogLib/Formatters/NullFormatter.h"

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

    using namespace QSLogLib;

    // add logging device for console and file	
    addLoggingDevice( new ConsoleLogger(new NullFormatter) ); // Console + nullFormat
    addLoggingDevice( new FileLogger("foo.log", new DetailedFormatter) ); // File + detailedFormat

    // The following line writes the message to both console and file.
    int a = 10;
    double b = 15.3;
    const char* c = "Success";
    SLOGLIB_LOG_MSG_INFO("a = " << a << " b = " << b);
    SLOGLIB_LOG_MSG_INFO(c);

    return 0;
}

3️⃣ Logging Example for udp transmission

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

	using namespace QSLogLib;

	std::string strDestAddress = "192.168.137.1";
	unsigned short destPort = 5000;
	addLoggingDevice(new UdpLogger(strDestAddress, destPort, new NullFormatter));

	// The following line writes the message to UDP packet 
	int a = 10;
	double b = 15.3;
	const char* c = "Success";
	SLOGLIB_LOG_MSG_INFO("a = " << a << " b = " << b);
	SLOGLIB_LOG_MSG_INFO(c);

	return 0;
}
