Code analysis with clang-tidy in Visual Studio--Eli Fessler

The safest safety comes from the tools.

Code analysis with clang-tidy in Visual Studio

by Eli Fessler

From the article:

Visual Studio 2019 version 16.4 Preview 1 brings a significant improvement to the C++ code analysis experience: native support for clang-tidy, a Clang-based “linter” tool developed by the LLVM Project that delivers a variety of code improvements such as modernization and standards conformance, static analysis, and automatic formatting...

Expressive Code for State Machines in C++--Valentin Tolmer

Compiler checks are the best!

Expressive Code for State Machines in C++

by Valentin Tolmer

From the article:

Have you ever run into this kind of comments?

// IMPORTANT: Do not call this function before calling SetUp()!

Or checks like these:

if (my_field_.empty()) abort();

Those are all symptoms of a (often light-weight) protocol that our code must respect. Or sometimes, you have an explicit protocol that you’re following, such as in the implementation of an SSL handshake or other business logic. Or maybe you have an explicit state machine in your code, with the transitions checked each time against a list of possible transitions.

Let’s have a look at how we can expressively handle these cases...

Simplify Your Code With Rocket Science: C++20’s Spaceship Operator--Cameron DaCamara

Simplify Your Code With Rocket Science: C++20’s Spaceship Operator

by Cameron DaCamara

From the article:

C++20 adds a new operator, affectionately dubbed the “spaceship” operator: <=>. There was a post awhile back by our very own Simon Brand detailing some information regarding this new operator along with some conceptual information about what it is and does.  The goal of this post is to explore some concrete applications of this strange new operator and its associated counterpart, the operator== (yes it has been changed, for the better!), all while providing some guidelines for its use in everyday code.
