Maintainer activity

14 people did triage or write work on this repository in the last 12 months.

Counts unlabeled, assigned, unassigned, milestoned, demilestoned, locked, unlocked over the last 12 months. These are issue and pull request events that require triage or write permission. Commits and code review are not counted. labeled and renamed are excluded because GitHub issue forms record the issue author as the actor. Figures from October 18, 2026. This count is not comparable across projects: each project's automation decides which of these events a person emits. How this is counted.

How this project is maintained

About 16% of issues opened in the past year have never received a reply. 97% of open issues come from outside the core team, so the backlog reflects real-world use rather than internal planning. Work labelled "Druntime" is answered fastest, typically in about 8 hours, while "OS:Windows" waits about 2 weeks. 55% of tracked open issues have had no activity in three months. 62% of issues opened in the past year have been closed, leaving a working backlog.

Detailed Description

DMD is the reference compiler for the D programming language.

DMD addresses the need for a compiler that can translate D language source code into native executables. The compiler is structured modularly, with distinct components for the frontend compiler logic, runtime support through druntime, and comprehensive testing infrastructure. The project maintains a changelog for upcoming releases and provides predefined configuration files to support different build environments.

Developers should choose DMD if they are working with the D programming language or contributing to its ecosystem. The tool suits projects ranging from systems programming to general-purpose applications written in D. As the reference implementation, DMD defines the standard behavior and capabilities of the language itself, making it essential for anyone developing in D or maintaining D libraries.

The project maintains active development with regular nightly builds generated from the master branch, indicating continuous integration and testing. The codebase includes dedicated testing infrastructure and comprehensive internal documentation. The repository accepts community contributions through established guidelines for bug reporting and development, with participation encouraged through community events.
