Q: Does Icecream-cpp work with C++20 ranges?

Yes, it fully supports C++20 ranges and can lazily inspect pipeline data using IC_V(), as demonstrated with std::views examples in the range views pipeline section.

Q: How to handle wide strings in Icecream-cpp?

Use the wide_string_transcoder configuration option to define a custom function for transcoding wchar_t strings to char, since the default may not handle all encodings correctly, as explained in character encoding.

Q: Can I use Icecream-cpp with Boost or Range-v3?

Yes, it optionally supports Boost types and Range-v3 views via macros like ICECREAM_RANGE_V3 or header inclusion order, but this requires explicit enabling or careful setup, as noted in third-party libraries.

Question 1

How to disable Icecream-cpp in production?

Accepted Answer

Define the ICECREAM_DISABLE macro before including the header, or use compiler flags like -DICECREAM_DISABLE. This disables printing but keeps configuration functional, as noted in the macro disabling section.

Question 2

Icecream-cpp vs spdlog for C++ debugging?

Accepted Answer

Icecream-cpp is focused on expressive, quick print debugging during development with concise macros, while spdlog is a full-featured logging library suited for production with structured output and performance optimizations.

Question 3

How to print custom types with Icecream-cpp?

Accepted Answer

Ensure your type is printable by a baseline strategy like providing an operator<< overload for IOStreams, or a formatter for {fmt}/std::format. The library checks strategies in precedence order, as detailed in printing strategies.
