C++ is a powerful and widely-used programming language that is constantly evolving to meet the needs of modern software development. If you’re a C++ developer, it is important to understand how new features are proposed and adopted in the language. In this blog post, we will delve into the process of proposing and adopting new features in C++.
The Evolution Working Group
The C++ Standardization Committee (also known as WG21) is responsible for managing the evolution of the C++ programming language. Within this committee, there is a dedicated team called the Evolution Working Group (EWG) that focuses on proposing and reviewing new language features.
The EWG consists of C++ experts and enthusiasts who collaborate to improve the language by proposing, discussing, and reviewing new ideas. Contributors submit proposals in the form of documents, explaining the problem they aim to solve, the proposed solution, and examples showcasing the syntax and usage.
The Proposal Review Process
Once a proposal is submitted, it goes through a rigorous review process to ensure that the proposed feature aligns with the goals and principles of C++ and doesn’t introduce any negative consequences. The review process typically consists of the following stages:
-
Preparation: The proposal author prepares the proposal document, addressing the problem, solution, and potential impact on the language and existing code.
-
Initial Review: The proposal is reviewed by the EWG members, who provide feedback, ask questions, and suggest improvements. This stage aims to catch any major issues early on.
-
Revision: Based on the feedback received during the initial review, the proposal author revises the document, making necessary changes and addressing concerns raised by the reviewers.
-
Final Review: The revised proposal document is presented to the EWG for a final round of review. This is where the proposal is scrutinized in detail, and any potential pitfalls or compatibility issues are thoroughly examined.
-
Consensus: The proposal must achieve a consensus within the EWG for it to move forward. If there are unresolved disagreements, further discussions and revisions may be required.
-
Standardization: If a proposal gains consensus within the EWG, it moves to the next stage, where it undergoes a more formal review process as part of the C++ Standardization process. The proposal is discussed and refined further, and ultimately, it may be included in the official C++ Standard.
Contributing to C++ Evolution
If you’re passionate about C++ and want to contribute to the language’s evolution, you can get involved in the process of proposing and adopting new features. Here are a few ways to actively contribute:
-
Stay informed: Follow the discussions and proposals on the C++ Standardization Committee’s mailing lists and attend C++ conferences to stay up-to-date with the latest developments.
-
Submit proposals: If you have a new feature or improvement idea, prepare a proposal document and submit it to the EWG for review. Be sure to present your case clearly, providing solid reasoning and examples.
-
Participate in discussions: Engage in discussions on the mailing lists and forums to share your insights, ask questions, and provide constructive feedback on existing proposals.
-
Review and provide feedback: Participate in the review process by providing feedback on proposals. Your perspective and insights can help shape the future of C++.
Conclusion
Understanding the process of proposing and adopting new features in C++ is crucial for any C++ developer who wants to stay up-to-date with the latest language advancements. By actively participating in the evolution of C++, you can contribute to the language’s growth and help shape its future. So, stay informed, engage in discussions, and submit your ideas to ensure that C++ continues to meet the needs of the ever-changing software development landscape.
