Partially Mocking an ES Module with Jest and Node.js
Disclaimer: This article has nothing to do with C++. Also, I do not have a huge amount of experience with the Node.js ecosystem. This information is provided here because of the issues I had reading...
View ArticleDesigning Classes for Serialization (2)
The complement of serialization is deserialization, and this is typically more difficult as it requires character- or pattern-matching of the input, plus checking for erroneous input. To match a stream...
View ArticleDesigning Classes for Serialization (3)
In the previous articles we’ve looked at creating an in-memory XML hierarchy (or DOM), and serializing from and deserializing to this memory model. In this article we’re going to look at querying the...
View ArticleDesigning Classes for Serialization (4)
In the previous articles of this mini-series we’ve covered the use of custom serialization and deserialization functions to generate and interpret XML. In this article we’ll look at how to add to...
View ArticleApplying Functional Programming Techniques to Modern C++
Functional programming (FP) is a discipline and practice of computer science where Mathematical concepts come to the fore. There are a number of popular FP languages out there, but we can stay with C++...
View ArticleDesigning Traits and Policy Classes
Traits and policy classes are often used with C++ generics, but their role and purpose is often something of an enigma even to experienced C++ programmers. The definitions of these two terms overlap to...
View ArticleConcepts 101
Concepts finally appeared in the language with the completion of C++20—I say finally as work to specify them had been going on continuously since before the release of C++11. This article attempts to...
View ArticleSelecting Functions at Compile Time
When writing C++, we like to do as much of the work as possible at compile time; with C++ being a statically-typed language, we know the type(s) involved when compilation is taking place. In this...
View ArticleSignaling error conditions without exceptions
In this article we’re going to look at a feature new to C++23 which supports a way to return an error condition from a function where a result value was anticipated. This is enabled in a new header...
View ArticleSelecting Functions at Runtime
Not all choices can be made at compile-time, sometimes including which function (of several possibilities) to invoke. This article aims to cover all of the methods available to Modern C++ when...
View ArticleModern C++ 101: Refactoring Legacy Code
So here’s a program written in a hurry, possibly in the style of a college CS student in about week six of learning C++ as a taught course. It’s simple, it works, and it can (naturally) be improved...
View ArticleReplacing the Preprocessor in Modern C++
Back in the early days when the original C++ compiler compiled into C, it seemed natural to use the existing C preprocessor to add C (and C++) headers to each source file in order to create a coherent...
View ArticleLinear Algebra support in C++26
It’s likely that you’re already familiar with std::string_view and std::span<T> in Modern C++, each of which provides a lightweight “view” onto either string data or other contiguous typed data...
View ArticleExploring C++23’s flat_map
This article intends to examine how to utilize the container adapter std::flat_map, new to the C++23 Standard Library. You’re probably familiar with std::map and std::unordered_map (and their “multi”...
View ArticleUsing Lambda Functions for Delayed Evaluation
Lambda functions (sometimes called “anonymous functions”) have been a part of C++ for many years now, so usage of them should be well accepted. This mini-article is intended to outline a use case for...
View ArticleMemory Allocation Techniques in Modern C++
C++ has always been regarded as a high-performance programming language, in no small part because its memory handling capabilities are close to the machine hardware. Modern C++ continues this tradition...
View ArticleUses of Parser Generators
We tend to think of parser generators as being used to implement the front-end of a programming language compiler, and having graduated from writing the desk-calculator program this is typically what...
View ArticleUnderstanding Iterator Invalidation
As introduced in the Tutorial on this site, practising correct use of iterators is essential for correct and efficient use of the Standard Containers. This article aims to uncover the details of...
View ArticleRange-for enhancements in C++23
The latest C++ Standard has been with us for a while now, and in this article we’re going to take a look at a couple of useful enhancements to the range-for syntax we’ve used since C++11. Iterating...
View ArticlePattern Matching is coming to Modern C++
Pattern matching is a commonly used idiom in other contemporary programming languages, such as Rust or Haskell, and is a way to inspect and deconstruct value(s) based on their type(s). Unlike...
