The Beman Project: Elevating C++ Standard Libraries
0:00 Introduction: David Sankel introduces the Beman Project, a new community initiative focused on enhancing the quality of C++ standard library proposals. The project is named in memory of Beman Dawes.
0:41 Motivation and Background: The project arose from observations that the C++ standardization process primarily focuses on papers rather than iterating on usable implementations. This contrasts with industry practices (e.g., at Adobe) where prototyping, user feedback, and iterative development are crucial.
4:36 Standard Library Proposal Process: Description of how a proposal makes it into the standard, starting with a study group and ending with inclusion in the working draft.
8:06 What moves through the process?: A paper moves through the process. Proposals have implementations, but the paper is the focus.
10:58 Early Ideas: Jeff Garland and Inbal Levy independently recognized the need for incorporating implementation feedback into the standardization process. This led to the initial concept for the Beman Project.
13:32 Boost Foundation. The speaker and Jeff Garland proposed to the Boost Foundation to create a new project to get feedback and incorporation of standard libraries.
14:08 Project Launch (C++Now 2024): The project officially launched at C++Now 2024, with a concentrated effort to define its mission, vision, and initial structure.
15:14 Mission Statement: The Beman Project's mission is to "support the efficient design and adoption of the highest quality C++ standard libraries through implementation experience, user feedback, and technical expertise."
16:10 Naming: The project is named after Beman Dawes, co-founder of Boost and long-time wg21 Library Working Group chair, known for his technical excellence and kindness.
17:44 Logo Creation: The Beman Project logo was inspired by a picture of Beman Dawes, initially drafted by Inbal Levy and refined using AI by Saksham Sharma.
19:19 Core Principles:
21:46 Administrative Details: Apache License with LLVM exceptions, naming conventions, directory layouts, and a focus on CMake best practices.
22:20 Lifetime of a Beman Library: Describes the lifecycle from paper proposal to Beman library, feedback collection, acceptance into the standard, and delisting after two standard cycles (6 years) post-publication. This encourages adoption of the standard library and avoids legacy accumulation.
25:10 Example Libraries:
34:16 Beman.Exemplar: A repository serving as a "cookie-cutter" template for new Beman libraries and a showcase of best practices for C++ open-source projects (unit testing, CMake, documentation, sanitizers, CI, etc.). Includes GitHub features like automated code formatting feedback and in-browser editing via code spaces.
38:16 Community Discussions: Highlights the value of open discussions within the Beman community, citing an example about unit testing frameworks (Lit) that led to significant learning and knowledge sharing.
39:32 "Dawes Discussions": Laura Savino's idea to mark key discussions as "Dawes Discussions" for easy access and reference.
39:57 Early Results: Several libraries have provided standard feedback, resulting in changes.
41:58 Available and In-Development Libraries: Overview of libraries that developers can start using now, even before they are officially part of the C++ standard.
44:38 Contribution Opportunities:
46:18 "Hell's 15" Story: A real-world example demonstrating the welcoming and inclusive nature of the project, where a beginner contributor successfully implemented Beman::inplace_vector.
47:56 Contributors. The leads, core and other contributors were named.
48:54 Call to Action: Encourages attendees to explore the Beman Project, find areas of interest, collaborate, and contribute, emphasizing the open and accessible nature of the project.
50:45 Q&A. Various questions from the audience, such as using language features not present in older C++ versions, how to introduce beginners to the Beman project, compiler support, dependencies between libraries, and stability.
