Meta

This document discusses the high-level vision for D with semestrial granularity. It is released in January and July of each year. Note that the goals presented are those 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.

H2 2017 Review

The D Language Foundation
Expenses for H1 2017 have averaged at $1605 per month. These include mostly recurring expenses (scholarships, contract payments).
The Foundation has funds for over three years assuming no changes in expenses and no money inflow. We, however, expect both donations and expenses to increase.
The scholarship recipients have created 154 pull requests.
Organization
The core team (Walter Bright, Andrei Alexandrescu, Ali Cehreli, Martin Nowak, Vladimir Panteleev, and Sebastian Wilzbach, Mike Parker) kept operations working. There are new potential core collaborators.
Participation
H2 2017 has marked a 28.5% increase in total pull requests compared to to H2 2016: 1812 vs. 1410. Of these, 124 are open.
We have continued to grant merge rights to strong contributors and fostered an increase in contribution quality and esprit de corps.
Downloads of dmd have increased substantially, but we assume the data collection is imperfect because it does not account for repeated downloads from the same URL. So bots, repeated unsuccessful attempts, or manipulation can influence the statistics. We are working on a better tool.
Safety and Memory Management
Work on safe containers has slowed down but is still ongoing.
Of new note is Alexandru Jercaianu's work on a new allocator that offers a safe free primitive. That opens new avenues for approaching memory management.
