value-category-cheatsheet
A PDF cheatsheet explaining C++14 value categories (lvalues, rvalues, xvalues) with practical examples and edge cases.
What is value-category-cheatsheet?
jeaye/value-category-cheatsheet is a generated PDF cheatsheet that explains C++14 value categories, including lvalues, rvalues, and xvalues, with practical examples and edge cases. It helps C++ developers understand and avoid common pitfalls related to value semantics in their code.
C++ developers working with C++11 or C++14 codebases who need a quick reference for understanding value categories and their implications in everyday programming.
It provides a concise, practical reference focused on real-world scenarios rather than theoretical explanations, making it especially useful for developers maintaining or working in existing C++ projects.
Overview
A C++14 cheat-sheet on lvalues, rvalues, xvalues, and more
Use Cases
Best For
- Understanding C++14 value categories quickly
- Debugging issues related to lvalues and rvalues
- Learning practical C++ semantics for existing codebases
- Referencing edge cases in C++ value category rules
- Preparing for C++ interviews or code reviews
- Complementing C++ learning with real-world examples
Not Ideal For
- Teams migrating to or exclusively using C++17 or newer standards, as it omits updated value category rules.
- Developers preferring interactive, searchable documentation over static PDF references for quick lookups.
- Educators needing a comprehensive theoretical foundation rather than a practical cheat sheet for teaching C++ semantics.
Pros & Cons
Pros
Emphasizes real-world coding scenarios and edge cases from everyday C++ work, making it directly applicable for debugging and reference.
Available as a generated PDF that can be viewed online or downloaded offline, ensuring accessibility without setup.
Tailored for existing codebases using C++11 and C++14 rulesets, as stated in the README, providing targeted relevance.
Created to accompany a talk by an experienced developer, offering distilled knowledge from practical C++ intricacies.
Cons
Does not cover changes in C++17 and beyond, limiting its utility for projects adopting newer standards, as admitted in the README.
As a PDF, it lacks searchability, interactivity, and updates compared to dynamic online resources or integrated development tools.
Regenerating the PDF requires installing Clojure, Ring, and wkhtmltopdf, adding overhead for customization or updates.
