What are the best string formatting libraries in C++17?

In C++17, some of the best string formatting libraries include {fmt}, std::format, and Boost.Format. Would you like to know more about any specific one?

Can you explain how to use the {fmt} library?

Sure! The {fmt} library allows you to format strings using a syntax similar to Python's f-strings. You can include placeholders in your string and pass values to format them. For example: fmt::format("Hello, {}!", name);.

What are the advantages of using std::format over other libraries?

std::format is part of the C++20 standard, providing a consistent and type-safe way to format strings. It integrates well with the standard library and offers compile-time checks.

Are there any performance considerations when using these libraries?

Yes, performance can vary between libraries. Generally, {fmt} is known for its speed, while std::format may have some overhead due to its type safety. It's best to benchmark based on your specific use case.
