## Project history and usage

dfmt is a formatter for D source code. It can read from stdin or a file, write formatted output to stdout, edit files in place, and use EditorConfig files for formatting settings.

### Project history

The official tag history begins in 2015 with the 0.1.x series. The README describes the tool as beta quality and documents both DUB and source builds, reflecting its role inside the D language tooling ecosystem.

### Adoption history

dfmt follows the formatter pattern familiar from other language communities: a small command-line tool that can be invoked directly, integrated into editors, or run by project scripts while reading shared formatting policy from `.editorconfig`.

### How it is used

By default dfmt reads D source from stdin and writes to stdout. When given a file and `--inplace`, it rewrites that file, while command-line options can override settings discovered through applicable `.editorconfig` files.

### Why package nerds care

For package nerds, dfmt is the D ecosystem's conventional formatting binary: packaging it gives editors and build scripts a reproducible formatter without requiring each project to vendor the formatter itself.

### Timeline

- 2015: v0.1.0 appears in the official tag history.
- 2023: v0.15.0 is tagged after beta releases.
- 2024: v0.15.2 is tagged.

### Related projects

- dfmt is related to DUB, D compiler toolchains such as DMD and LDC, EditorConfig, and libdparse.
