C++ Idioms

Disclaimer: Grok generated document.

C++ idioms are recurring patterns or techniques used by experienced programmers to write robust, efficient, and maintainable code. They leverage C++'s features to solve common problems or express intent clearly. Below is a comprehensive overview of key C++ idioms, organized by their purpose and functionality. This list covers both classic idioms and modern ones introduced with evolving C++ standards (up to C++20 and some C++23 insights where relevant). I’ll keep the explanations concise yet informative, focusing on the idiom, its purpose, and a brief example where necessary.

1. Resource Management Idioms

These idioms ensure proper resource handling, preventing leaks and ensuring exception safety.

Hyprland Intuitive Keybind Config

Hyprland keybinding configuration syntax is not for humans.

I made a little script so you can write keybinding config with short and intuitive syntax.

The script will write the transpiled config into hyprland.conf

📌 Comprehensive Comparison of C++ Build Systems

Choosing the right build system for C++ projects can significantly impact compilation speed, dependency management, and portability. This guide compares CMake, Meson, Bazel, Autotools, MSTools, and other alternatives.

During the past days, this great article by Sam Pruden has been making the rounds around the gamedev community. While the article provides an in-depth analysis, its a bit easy to miss the point and exert the wrong conclusions from it. As such, and in many cases, users unfamiliar with Godot internals have used it points such as following:

Godot C# support is inefficient
Godot API and binding system is designed around GDScript
Godot is not production ready

In this brief article, I will shed a bit more light about how the Godot binding system works and some detail on the Godot

Generic Elm types exercises

A series of exercises to get a feel for how generic types and type variables work in Elm. For each of these, you are given some code that is not compiling. Your task is to get it compiling. You can change the body of the function but not the signature. No cheating with Debug.todo or infinite recursions either 😉

Elm Types Glossary

There's a lot of type terminology and jargon going around when discussing types in Elm. This glossary attempts to list some of the most common type terms along with synonyms, terms from other language communities, examples, and links to more detailed articles on each topic.
