Icecream-cpp is a print debugging tool that shows where you are in the code (file, line, and function name), variable names and values, values flowing in a range views pipeline. That all as easily, configurable, and formattable as possible. You can format values in C++11 with the same syntax C++20 Formatting library, show ranges with the same Python slicing syntax, and print classes without support of any base formatting library (IOStreams, STL Formatting, and {fmt}) when using Clang.
