+# spdlog
+
+spdlog is very fast, header only, c++11 logging library.
+
+
+## Install
+Just copy the files to your build tree and use a C++11 compiler
+
+
+## Tested on:
+* gcc 4.8.1 and above
+* clang 3.5
+* visual studio 2013
+
+##Features
+* Stream like, east to use interface
+* Logging levels
+* Rotating log files
+* Daily log files
+* Async logging
+* Thread safety
+* Very low overhead
+
+## Performance
+The library is very fast. 
+Here are some benchmarks  (Ubuntu, Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz)
+```

+```
+
+## Usage Example
+```
+#include <iostream>
+#include "spdlog/spdlog.h"
+
+int main(int, char* [])
+{
+    namespace spd = spdlog;
+
+    try
+    {
+        std::string filename = "spdlog_example";
+        auto console = spd::stderr_logger_mt("console");
+        console->info("Welcome to spdlog!") ;
+        console->info() << "Creating file " << filename << "..";
+
+        auto file_logger = spd::rotating_logger_mt("file_logger", filename, 1024 * 1024 * 5, 3);
+        file_logger->info("Log file message number", 1);
+
+        for (int i = 0; i < 100; ++i)
+        {
+            auto square = i*i;
+            file_logger->info() << i << '*' << i << '=' << square << " (" << "0x" << std::hex << square << ")";
+        }
+
+        // Change log level to all loggers to warning and above
+        spd::set_level(spd::level::WARN);
+        console->info("This should not be displayed");
+        console->warn("This should!");
+        spd::set_level(spd::level::INFO);
+
+        // Change format pattern to all loggers
+        spd::set_pattern(" **** %Y-%m-%d %H:%M:%S.%e %l **** %v");
+        spd::get("console")->info("This is another message with different format");
+    }
+    catch (const spd::spdlog_ex& ex)
+    {
+        std::cout << "Log failed: " << ex.what() << std::endl;
+    }
+    return 0;
+}

-========================================================================

-    STATIC LIBRARY : c11log Project Overview

-========================================================================

-

-AppWizard has created this c11log library project for you.

-

-This file contains a summary of what you will find in each of the files that

-make up your c11log application.

-

-

-c11log.vcxproj

-    This is the main project file for VC++ projects generated using an Application Wizard.

-    It contains information about the version of Visual C++ that generated the file, and

-    information about the platforms, configurations, and project features selected with the

-    Application Wizard.

-

-c11log.vcxproj.filters

-    This is the filters file for VC++ projects generated using an Application Wizard. 

-    It contains information about the association between the files in your project 

-    and the filters. This association is used in the IDE to show grouping of files with

-    similar extensions under a specific node (for e.g. ".cpp" files are associated with the

-    "Source Files" filter).

-

-

-/////////////////////////////////////////////////////////////////////////////

-

-StdAfx.h, StdAfx.cpp

-    These files are used to build a precompiled header (PCH) file

-    named c11log.pch and a precompiled types file named StdAfx.obj.

-

-/////////////////////////////////////////////////////////////////////////////

-Other notes:

-

-AppWizard uses "TODO:" comments to indicate parts of the source code you

-should add to or customize.

-
