Ways to Refactor Toggle/Boolean Parameters in C++

by Bartlomiej Filipek

From the article:

Boolean parameters in a function might be misleading and decrease its readability. If you have a poorly named function like:

DoImportantStuff(true, false, true, false);

As you can imagine, it’s not clear what all those parameters mean? What’s the first true? What does the last false mean? Can we improve code in such cases?

Let’s have a look at possible improvements...

My favorite C++20 feature

by Marius Elvert

From the article:

As I evolved my programming style away from mutating long-lived “big” objects and structures and towards are more functional and data-oriented style based mainly on pure functions, I also find myself needing a lot more structs. These naturally occur as return types for functions with ‘richer’ output if you do not want to use std::tuple or other ad-hoc types everywhere. If you see a program as a sequence of data-transformations, I guess the structs are the immediate representations encoded in the type system...

How to Use C++20 Modules with Bazel and Clang--Ryan Burn

Modules are coming.

How to Use C++20 Modules with Bazel and Clang

by Ryan Burn

From the article:

Modules are a feature added to C++20 that aims to provide better encapsulation and faster build times. While modules are not fully supported by compilers and probably not ready for use in production code, Clang’s support is fairly usable.

In this guide, I’ll show you how to use modules with Clang and the Bazel build system by making use of the project github.com/rnburn/rules_cc_module.

Let’s look at it works on a simple hello world program...

Have you ever used it?

constexpr if

by Rainer Grimm

From the article:

In today's post, I want to introduce a very interesting C++17 feature: constexpr if. constexpr if enables it to conditionally compile source code and can also be used for nice tricks at compile time...
