-## Usage samples
-
-#### Basic usage
-```c++
-#include "spdlog/spdlog.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 {}", {});
-    SPDLOG_DEBUG("Some debug message");
-        
-}
-```
-#### 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);
-}
-
-```
-
----
-#### Cloning loggers 
-```c++
-// clone a logger and give it new name.
-// Useful for creating subsystem loggers from some "root" logger
-void clone_example()
-{
-    auto network_logger = spdlog::get("root")->clone("network");
-    network_logger->info("Logging network stuff..");
-}
-```
-
----
-#### Periodic flush
-```c++
-// periodically flush all *registered* loggers every 3 seconds:
-// warning: only use if all your loggers are thread safe!
-spdlog::flush_every(std::chrono::seconds(3));
-
-```
-
----
-#### Binary logging
-```c++
-// log binary data as hex.
-// 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});
-}
-
-```
----
-#### 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);
-    syslog_logger->warn("This is warning that will end up in syslog.");
-}
-```
----
-#### Android example 
-```c++
-#include "spdlog/sinks/android_sink.h"
-void android_example()
-{
-    std::string tag = "spdlog-android";
-    auto android_logger = spdlog::android_logger("android", tag);
-    android_logger->critical("Use \"adb shell logcat\" to view this message.");

+## Usage samples
+
+#### Basic usage
+```c++
+#include "spdlog/spdlog.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 {}", {});
+    SPDLOG_DEBUG("Some debug message");
+
+}
+```
+#### 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);
+}
+
+```
+
+---
+#### Cloning loggers
+```c++
+// clone a logger and give it new name.
+// Useful for creating subsystem loggers from some "root" logger
+void clone_example()
+{
+    auto network_logger = spdlog::get("root")->clone("network");
+    network_logger->info("Logging network stuff..");
+}
+```
+
+---
+#### Periodic flush
+```c++
+// periodically flush all *registered* loggers every 3 seconds:
+// warning: only use if all your loggers are thread safe!
+spdlog::flush_every(std::chrono::seconds(3));
+
+```
+
+---
+#### Binary logging
+```c++
+// log binary data as hex.
+// 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});
+}
+
+```
+---
+#### 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);
+    syslog_logger->warn("This is warning that will end up in syslog.");
+}
+```
+---
+#### Android example
+```c++
+#include "spdlog/sinks/android_sink.h"
+void android_example()
+{
+    std::string tag = "spdlog-android";
+    auto android_logger = spdlog::android_logger("android", tag);
+    android_logger->critical("Use \"adb shell logcat\" to view this message.");
+}
+```
