Question 1

How to enforce C++ Core Guidelines in my codebase?

Accepted Answer

Use static analysis tools like Clang-Tidy with GSL integration, start by focusing on high-priority safety rules such as resource management, and adopt guidelines gradually to minimize disruption.

Question 2

C++ Core Guidelines vs Google C++ Style Guide: which should I use?

Accepted Answer

C++ Core Guidelines emphasize modern C++ and high-level safety for architecture, while Google's guide includes more low-level style conventions; choose based on whether you need foundational best practices or detailed coding standards.

Question 3

What is the Guidelines Support Library (GSL) and is it mandatory?

Accepted Answer

GSL is a header-only library providing utilities like gsl::span for implementing guidelines; it's essential for following many rules but can be substituted if necessary, though alternatives may lack tool support.

Question 4

How often are the C++ Core Guidelines updated?

Accepted Answer

They are continuously evolving without a fixed schedule; version increments are tagged in git, so monitor the repository for changes that might affect your codebase.

Question 5

Can I use C++ Core Guidelines for safety-critical embedded systems?

Accepted Answer

Yes, but with adaptation; some rules assume modern C++ features not available on all embedded compilers, so evaluate guidelines against your system's constraints and toolchain support.

Question 6

How to handle exceptions to rules in C++ Core Guidelines?

Accepted Answer

The guidelines allow for real-world exceptions; document deviations clearly, use tool configurations to suppress specific rules, and ensure exceptions are justified for performance or safety reasons.
