How do I use fmt and spdlog for formatting and logging in C++?

In C++, formatting and logging can be efficiently handled using the libraries fmt and spdlog. These libraries facilitate the generation of formatted text and provide powerful logging capabilities with minimal overhead. Below is an example of how to use both of these libraries together for formatted output and logging in a C++ application.

This example demonstrates how to set up formatting and logging using fmt and spdlog in a C++ application.

C++, fmt, spdlog, formatting, logging

// Include the necessary headers #include #include #include int main() { // Set up logging auto logger = spdlog::stdout_color_mt("console"); logger->set_pattern("%^[%L] %v%$"); // Set log pattern // Log a message logger->info("This is an info log message."); // Using fmt to format a string std::string name = "World"; std::string greeting = fmt::format("Hello, {}!", name); // Log the formatted message logger->info(greeting); return 0; }
