-# spdlog
-
-Very fast, header-only/compiled, C++ logging library. [![Build Status](https://travis-ci.org/gabime/spdlog.svg?branch=master)](https://travis-ci.org/gabime/spdlog)  [![Build status](https://ci.appveyor.com/api/projects/status/d2jnxclg20vd0o50?svg=true)](https://ci.appveyor.com/project/gabime/spdlog) [![Release](https://img.shields.io/github/release/gabime/spdlog.svg)](https://github.com/gabime/spdlog/releases/latest)
-
-## Install 
-#### Header only version
-Copy the source [folder](https://github.com/gabime/spdlog/tree/v1.x/include/spdlog) to your build tree and use a C++11 compiler.
-
-#### Static lib version (recommended - much faster compile times)
-```console
-$ git clone https://github.com/gabime/spdlog.git
-$ cd spdlog && mkdir build && cd build
-$ cmake .. && make -j
-```
-      
-   see example [CMakeLists.txt](https://github.com/gabime/spdlog/blob/v1.x/example/CMakeLists.txt) on how to use.
-
-## Platforms
- * Linux, FreeBSD, OpenBSD, Solaris, AIX
- * Windows (msvc 2013+, cygwin)
- * macOS (clang 3.5+)
- * Android
-
-## Package managers:
-* Homebrew: `brew install spdlog`
-* MacPorts: `sudo port install spdlog`
-* FreeBSD:  `cd /usr/ports/devel/spdlog/ && make install clean`
-* Fedora: `yum install spdlog`
-* Gentoo: `emerge dev-libs/spdlog`
-* Arch Linux: `pacman -S spdlog`
-* vcpkg: `vcpkg install spdlog`
-* conan: `spdlog/[>=1.4.1]`
-* conda: `conda install -c conda-forge spdlog`
-
-
-## Features
-* Very fast (see [benchmarks](#benchmarks) below).
-* Headers only or compiled version
-* Feature rich formatting, using the excellent [fmt](https://github.com/fmtlib/fmt) library.
-* **New!** [Backtrace](#backtrace-support) support - store debug messages in a ring buffer and display later on demand.
-* Asynchronous mode (optional)
-* [Custom](https://github.com/gabime/spdlog/wiki/3.-Custom-formatting) formatting.
-* Multi/Single threaded loggers.
-* Various log targets:
-    * Rotating log files.
-    * Daily log files.
-    * Console logging (colors supported).
-    * syslog.
-    * Windows debugger (```OutputDebugString(..)```)
-    * Easily extendable with custom log targets  (just implement a single function in the [sink](include/spdlog/sinks/sink.h) interface).
-* Log filtering - log levels can be modified in runtime as well as in compile time.
-* Support for loading log levels from argv or from environment var.
-
- 
-## Usage samples
-
-#### Basic usage
-```c++
-#include "spdlog/spdlog.h"
-#include "spdlog/sinks/basic_file_sink.h"
-
-int main() 
-{
-    spdlog::info("Welcome to spdlog!");
-    spdlog::error("Some error message with arg: {}", 1);
-    
-    spdlog::warn("Easy padding in numbers like {:08d}", 12);
-    spdlog::critical("Support for int: {0:d};  hex: {0:x};  oct: {0:o}; bin: {0:b}", 42);
-    spdlog::info("Support for floats {:03.2f}", 1.23456);
-    spdlog::info("Positional args are {1} {0}..", "too", "supported");
-    spdlog::info("{:<30}", "left aligned");
-    
-    spdlog::set_level(spdlog::level::debug); // Set global log level to debug
-    spdlog::debug("This message should be displayed..");    
-    
-    // change log pattern
-    spdlog::set_pattern("[%H:%M:%S %z] [%n] [%^---%L---%$] [thread %t] %v");
-    
-    // Compile time log levels
-    // define SPDLOG_ACTIVE_LEVEL to desired level
-    SPDLOG_TRACE("Some trace message with param {}", 42);
-    SPDLOG_DEBUG("Some debug message");
-    
-    // Set the default logger to file logger
-    auto file_logger = spdlog::basic_logger_mt("basic_logger", "logs/basic.txt");
-    spdlog::set_default_logger(file_logger);            
-}
-
-```
-#### Load log levels from env variable or from argv
-```c++
-#include "spdlog/cfg/env.h"
-void load_levels_example()
-{
-    // Set the log level to "info" and mylogger to to "trace":
-    // SPDLOG_LEVEL=info,mylogger=trace && ./example
-    spdlog::cfg::load_env_levels();
-    // or from command line:
-    // ./example SPDLOG_LEVEL=info,mylogger=trace
-    // #include "spdlog/cfg/argv.h" // for loading levels from argv
-    // spdlog::cfg::load_argv_levels(args, argv);
-}
-```
-#### Create stdout/stderr logger object
-```c++
-#include "spdlog/spdlog.h"
-#include "spdlog/sinks/stdout_color_sinks.h"
-void stdout_example()
-{
-    // create color multi threaded logger
-    auto console = spdlog::stdout_color_mt("console");    
-    auto err_logger = spdlog::stderr_color_mt("stderr");    
-    spdlog::get("console")->info("loggers can be retrieved from a global registry using the spdlog::get(logger_name)");
-}
-```
----
-#### Basic file logger
-```c++
-#include "spdlog/sinks/basic_file_sink.h"
-void basic_logfile_example()
-{
-    try 
-    {
-        auto my_logger = spdlog::basic_logger_mt("basic_logger", "logs/basic-log.txt");
-    }
-    catch (const spdlog::spdlog_ex &ex)
-    {
-        std::cout << "Log init failed: " << ex.what() << std::endl;
-    }
-}
-```
----
-#### Rotating files
-```c++
-#include "spdlog/sinks/rotating_file_sink.h"
-void rotating_example()
-{
-    // Create a file rotating logger with 5mb size max and 3 rotated files
-    auto rotating_logger = spdlog::rotating_logger_mt("some_logger_name", "logs/rotating.txt", 1048576 * 5, 3);
-}
-```
-
----
-#### Daily files
-```c++
-
-#include "spdlog/sinks/daily_file_sink.h"
-void daily_example()
-{
-    // Create a daily logger - a new file is created every day on 2:30am
-    auto daily_logger = spdlog::daily_logger_mt("daily_logger", "logs/daily.txt", 2, 30);
-}
-
-```
-
----
-#### Backtrace support
-```c++
-// Loggers can store in a ring buffer all messages (including debug/trace) and display later on demand.
-// When needed, call dump_backtrace() to see them
-spdlog::enable_backtrace(32); // create ring buffer with capacity of 32  messages
-// or my_logger->enable_backtrace(32)..
-for(int i = 0; i < 100; i++)
-{
-  spdlog::debug("Backtrace message {}", i); // not logged yet..
-}
-// e.g. if some error happened:
-spdlog::dump_backtrace(); // log them now! show the last 32 messages
-
-// or my_logger->dump_backtrace(32)..
-```
-
----
-#### Periodic flush
-```c++
-// periodically flush all *registered* loggers every 3 seconds:
-// warning: only use if all your loggers are thread safe ("_mt" loggers)
-spdlog::flush_every(std::chrono::seconds(3));
-
-```
-
----
-#### Log binary data in hex
-```c++
-// many types of std::container<char> types can be used.
-// ranges are supported too.
-// format flags:
-// {:X} - print in uppercase.
-// {:s} - don't separate each byte with space.
-// {:p} - don't print the position on each line start.
-// {:n} - don't split the output to lines.
-
-#include "spdlog/fmt/bin_to_hex.h"
-
-void binary_example()
-{
-    auto console = spdlog::get("console");
-    std::array<char, 80> buf;
-    console->info("Binary example: {}", spdlog::to_hex(buf));
-    console->info("Another binary example:{:n}", spdlog::to_hex(std::begin(buf), std::begin(buf) + 10));
-    // more examples:
-    // logger->info("uppercase: {:X}", spdlog::to_hex(buf));
-    // logger->info("uppercase, no delimiters: {:Xs}", spdlog::to_hex(buf));
-    // logger->info("uppercase, no delimiters, no position info: {:Xsp}", spdlog::to_hex(buf));
-}
-
-```
-
----
-#### Logger with multi sinks - each with different format and log level
-```c++
-
-// create logger with 2 targets with different log levels and formats.
-// the console will show only warnings or errors, while the file will log all.
-void multi_sink_example()
-{
-    auto console_sink = std::make_shared<spdlog::sinks::stdout_color_sink_mt>();
-    console_sink->set_level(spdlog::level::warn);
-    console_sink->set_pattern("[multi_sink_example] [%^%l%$] %v");
-
-    auto file_sink = std::make_shared<spdlog::sinks::basic_file_sink_mt>("logs/multisink.txt", true);
-    file_sink->set_level(spdlog::level::trace);
-
-    spdlog::logger logger("multi_sink", {console_sink, file_sink});
-    logger.set_level(spdlog::level::debug);
-    logger.warn("this should appear in both console and file");
-    logger.info("this message should not appear in the console, only in the file");
-}
-```
-
----
-#### Asynchronous logging
-```c++
-#include "spdlog/async.h"
-#include "spdlog/sinks/basic_file_sink.h"
-void async_example()
-{
-    // default thread pool settings can be modified *before* creating the async logger:
-    // spdlog::init_thread_pool(8192, 1); // queue with 8k items and 1 backing thread.
-    auto async_file = spdlog::basic_logger_mt<spdlog::async_factory>("async_file_logger", "logs/async_log.txt");
-    // alternatively:
-    // auto async_file = spdlog::create_async<spdlog::sinks::basic_file_sink_mt>("async_file_logger", "logs/async_log.txt");   
-}
-
-```
-
----
-#### Asynchronous logger with multi sinks  
-```c++
-#include "spdlog/sinks/stdout_color_sinks.h"
-#include "spdlog/sinks/rotating_file_sink.h"
-
-void multi_sink_example2()
-{
-    spdlog::init_thread_pool(8192, 1);
-    auto stdout_sink = std::make_shared<spdlog::sinks::stdout_color_sink_mt >();
-    auto rotating_sink = std::make_shared<spdlog::sinks::rotating_file_sink_mt>("mylog.txt", 1024*1024*10, 3);
-    std::vector<spdlog::sink_ptr> sinks {stdout_sink, rotating_sink};
-    auto logger = std::make_shared<spdlog::async_logger>("loggername", sinks.begin(), sinks.end(), spdlog::thread_pool(), spdlog::async_overflow_policy::block);
-    spdlog::register_logger(logger);
-}
-```
- 
----
-#### User defined types
-```c++
-// user defined types logging by implementing operator<<
-#include "spdlog/fmt/ostr.h" // must be included
-struct my_type
-{
-    int i;
-    template<typename OStream>
-    friend OStream &operator<<(OStream &os, const my_type &c)
-    {
-        return os << "[my_type i=" << c.i << "]";
-    }
-};
-
-void user_defined_example()
-{
-    spdlog::get("console")->info("user defined type: {}", my_type{14});
-}
-
-```
-
----
-#### User defined flags in the log pattern
-```c++ 
-// Log patterns can contain custom flags.
-// the following example will add new flag '%*' - which will be bound to a <my_formatter_flag> instance.
-#include "spdlog/pattern_formatter.h"
-class my_formatter_flag : public spdlog::custom_flag_formatter
-{
-public:
-    void format(const spdlog::details::log_msg &, const std::tm &, spdlog::memory_buf_t &dest) override

-    spdlog::set_formatter(std::move(formatter));
-}
-
-```
-
----
-#### Custom error handler
-```c++
-void err_handler_example()
-{
-    // can be set globally or per logger(logger->set_error_handler(..))
-    spdlog::set_error_handler([](const std::string &msg) { spdlog::get("console")->error("*** LOGGER ERROR ***: {}", msg); });
-    spdlog::get("console")->info("some invalid message to trigger an error {}{}{}{}", 3);
-}
-
-```

----
-#### syslog 
-```c++
-#include "spdlog/sinks/syslog_sink.h"
-void syslog_example()
-{
-    std::string ident = "spdlog-example";
-    auto syslog_logger = spdlog::syslog_logger_mt("syslog", ident, LOG_PID);
