Hi all, Anyone on this? Regards, Olivier 2014-03-15 1:25 GMT+01:00 Olivier Tournaire :

Hi all,

I am trying to extract severity level from a log record, but i seems that I am doing it the wrong way. Here is the code I use:

void LogDockWidget::receiveLog(boost::log::record_view const& rec, const std::string& log) { logging::value_ref< logging::trivial::severity_level > level = logging::extract< logging::trivial::severity_level >("Severity", rec); // ... }

Here level.get() always returns "info". All my logs are done with the BOOST_LOG_TRIVIAL(...) macro. The formatter whereas displays correctly the severity level. Here is how it is defined:

void LogDockWidget::init_logging() { boost::shared_ptr< logging::core > core = logging::core::get();

typedef sinks::synchronous_sink< QTextEditFormattedSinkBackend > sink_t; boost::shared_ptr< sink_t > sink(new sink_t);

// ...

logging::add_file_log( keywords::file_name = logFilename, keywords::auto_flush = true, keywords::format = ( BUILD_LOG_FORMATTER() ) );

sink->set_formatter( BUILD_LOG_FORMATTER() );

core->add_sink(sink);

// Add attributes that we will use logging::add_common_attributes(); core->add_global_attribute( "ThreadID", attrs::current_thread_id()); }

#define BUILD_LOG_FORMATTER() \ expr::stream \ << "[" << expr::format_date_time< boost::posix_time::ptime

...

("TimeStamp", "%Y-%m-%d %H:%M:%S") << "] " \ << expr::attr<unsigned int>("LineID") << " " \ << ": <" << logging::trivial::severity << "> " \ << " [" << expr::attrattrs::current_thread_id::value_type("ThreadID") << "] " \ << expr::if_(expr::has_attr(scope_attribute)) \ [ \ expr::stream << "[" << scope_attribute << "] " \ ] \ << expr::message

Could you please let me know what I am doing wrong?

Regards,

Olivier
