问题 I'm trying to add colored log output for boost::log under linux. I read the following and I tried this: #define MY_LOG_ERROR() BOOST_LOG_TRIVIAL(error) << "\033[1;31" MY_LOG_ERROR() << "This is an error log." but it gives me the result below: [2016-07-11 17:23:16.328435] [0x00007f15f03d6780] [error] [1;31This is an error log. How to properly add colored log output to boost::log? 回答1: The proper way to customize output with Boost.Log is to use formatters. To set a formatter you will have to

问题 I need help to initialize the boost logging framework to simultaneously log to both a named log file and also the console - (the named log file will not require periodic rotation or any of that fancy setup per many of the boost tutorials). The logging text should go to both sinks (file and console) simultaneously, however I need to format the console output slightly differently as it will be viewed by a user. I was able to get the basics of logging to 2 separate sinks working using the boost

问题 I'm using Boost(1.55.0) Logging in my C++ application. I have been able to generate log of this format [2014-Jul-15 10:47:26.137959]: <debug> A regular message I want to be able to add source file name and line number where the log is generated. [2014-Jul-15 10:47:26.137959]: <debug> [filename:line_no] A regular message example: [2014-Jul-15 10:47:26.137959]: <debug> [helloworld.cpp : 12] A regular message Source Code: #include <boost/log/core.hpp> #include <boost/log/trivial.hpp> #include

问题 I'm using custom boost::log formatter for color coding the output log message, but I'm failing to find the proper way to add TimeStamp and ThreadID attributes to the log. When I'm using file logging I just write keywords::format = "[%TimeStamp%] [%ThreadID%] [%Severity%]: %Message%" as logging::add_file_log parameter. I want to have similar effect in the following custom formatter: void coloring_formatter(const logging::record_view& record, logging::formatting_ostream& stream) { auto severity

问题 I am using the example at the following link. https://www.boost.org/doc/libs/1_57_0/libs/log/doc/html/log/detailed/utilities.html#log.detailed.utilities.setup.settings_file My code is as follows. #include "stdafx.h" #include <iostream> #include <fstream> #include <boost/log/core.hpp> #include <boost/log/trivial.hpp> #include <boost/log/expressions.hpp> #include <boost/log/utility/setup/file.hpp> #include <boost/log/utility/setup/common_attributes.hpp> #include <boost/log/utility/setup/from

问题 I'm learning Boost. Following a tutorial, I try to set a filter on a sink by sending a reference to the method onlyWarnings. Brief: sink->set_filter(&onlyWarnings); In onlyWarnings: set["Severity"].extract<int>() // is always 0 I'm obviously missing something in my code and an important part of the tutorial.
