ff is a lightweight header-only C++ library designed to formatting strings. Customize outputs easily with placeholders and specifiers for decimal, hex, octal, binary, scientific, and more.
No need to build, just put ff.h into your project's include directory and you are ready to go!
In case if you want to build the library
mkdir build && cd build
cmake .. && makeAnd you can link with the static library in build/src/ named as ff
std::string result = ff::format("Decimal: {}, Hex: {0:x}, Binary: {b}", 255, 15);
std::cout << result; // Output: Decimal: 255, Hex: 0xFF, Binary: 0b1111
std::string result1 = ff::format("Pi: {.2}, Scientific: {s}", 3.14159f, 1000.0f);
std::cout << result1; // Output: Pi: 3.14, Scientific, 1.000000e+03
