Meta
This document discusses the high-level vision for D with semestrial granularity. It is released in January and July of each year.
Note: This document focuses on goals the D leadership works on, explicitly fosters, or strongly believes are important for the success of the D language. Other contributions are always welcome and do not need to be necessarily aligned with this document.
H1 2017 Review
- The D Language Foundation
- DConf 2017 organized with help from Sociomantic has been a success. The number of attendees (over 100) has been flat compared to DConf 2016.
- Expenses for H1 2017 have averaged at $5600 per month. These include recurring expenses (scholarships, contract payments) as well as one-time items (legal, accounting, travel reimbursements for DConf 2017).
- The conference registration proceeds, training engagements, and donations have maintained our financial health.
- The scholarship recipients have created 57 pull requests. Each delivered a status report on their respective projects at DConf 2017.
- Organization
- Operation has been smooth with the help of Martin Nowak, Vladimir Panteleev, and Sebastian Wilzbach.
- Mike Parker accepted increasing formal responsibilities in public relations and DIP management.
- Participation
- H1 2017 has been flat in total pull requests compared to to H1 2016: 1698 vs. 1702. Of these, 178 are open indicating that reviews are a bottleneck of increasing the PR traffic.
- We have added merge rights to three contributors and are looking for more.
- The new DIP process is enjoying good success so far with two accepted, one postponed, and two rejected.
- Peak 28-day moving average of dmd downloads from the main site has been 1793.14 downloads/day on 2017-04-19. This is lower than our absolute record (2197.39 on 2016-11-18 attributed to Andrei's visit in China) but it is the second all-time best and a 17% increase over the best in H1 2016 (1527.07 2016-05-01).
- Safety and Memory Management
- Work on safe containers has made significant progress and has prompted improvements to allocators that are still ongoing.
- There has been progress but not sufficient to deem the matter addressed.
H2 2017 Priorities
Technical
The three main goals of the remainder of 2017 are:
1. @safety: we aim to enable large-scale uses of D with safety guarantees.
2. @nogc: Use of D without a garbage collector, most likely by using reference counting and related methods Unique/Weak references) for reclamation of resources. This task is made challenging by the safety requirement.
3. Improve interoperability with other languages: Finishing -betterC should improve incremental migration of C and C++.
Of these, the first two are the same as in the first half.
- static introspection remains an important strategic advantage of D and we should continue to improve both compiler support and library support. The static foreach DIP by Timon Gehr is a major development in the area.
- dub fixes+improvements
- add core.aa (https://github.com/dlang/druntime/pull/1282)
- safe RC/Unique/WeakRef implementations (core.rc)
- better error messages for template constraints (C++ concepts)
- transition website docs to dpl-docs/ddox
- partial and parallel recompilation (fix issues with scalable build methods, e.g. template instance emission)
- more lazy semantics
Non-Technical
- Make it easier for people to contribute (aka remove entry barriers)
- add more tooling to help with initial problems (e.g. DLang-Bot)
- improve contributor documentation and getting started (should be done by people who haven't seen the DMD/Phobos setup & codebase)
- encourage the "a fix is only a PR away" mentality (e.g. by means of blog post(s))
- reduce barrier of entry for potential contributors (e.g. bugzilla/forums registration)
- Increase motivation of existing contributors
- avoid PRs being stalled in the review queue
- increase interaction/communication between contributors. NG, mailing list, IRC, Slack
- make it easy for contributors to adopt a small-scale project (e.g. approved functions to Phobos, ...)
- promote the beginner/bootcamp Bugzilla tags (they are currently hard to find)
- publish blog post(s) about a "success story" such as this one
- foster a positive, constructive, and professional environment
