Detailed Description

The Log class.

Example:

#include <AsyncFw/Version>
#include <AsyncFw/MainThread>
#include <AsyncFw/Log>
 
int main(int argc, char *argv[]) {
  AsyncFw::Thread logThread {"LogThread"};
  logThread.start();
  logThread.invokeMethod([]() { AsyncFw::Instance<AsyncFw::Log>::create(1000, "log-file-name"); }, true);
 
  AsyncFw::Log::instance()->setColorOut(true);
 
  logNotice() << "Version:" << AsyncFw::Version::str();
  logNotice() << "Git:" << AsyncFw::Version::git();
 
  lsTrace() << "Trace";
  lsDebug() << "Debug";
  lsInfo() << "Info";
  lsInfoRed() << "Info red";
  lsInfoGreen() << "Info green";
  lsInfoBlue() << "Info blue";
  lsInfoMagenta() << "Info magenta";
  lsInfoCyan() << "Info cyan";
  lsNotice() << "Notice";
  lsWarning() << "Warning";
  lsError() << "Error";
 
  logTrace() << "Trace";
  logDebug() << "Debug";
  logInfo() << "Info";
  logNotice() << "Notice";
  logWarning() << "Warning";

  AsyncFw::Thread::currentThread()->invokeMethod([]() { AsyncFw::MainThread::exit(); });
 
  int ret = AsyncFw::MainThread::exec();
 
  AsyncFw::Log::instance()->append({AsyncFw::LogStream::Info, "Log", "Application finished", ""});
