The README presents it as a modern successor to Jessie Frazelle's earlier `dockfmt`, built on the Moby BuildKit parser and using `shfmt` for shell fragments inside Dockerfile `RUN` steps. The project quickly moved through 0.2.x releases in April 2025 and reached 0.5.4 in June 2026. The README's feature set includes whitespace normalization, inline-comment preservation, legacy `ENV key value` conversion, deprecated `MAINTAINER` conversion to `LABEL`, heredoc support, stdin/file operation, pre-commit support, JS/WASM bindings, and a Docker image for CI. ### 採用の歴史 Because dockerfmt is new, public adoption evidence is still thin. Its package-manager footprint is nevertheless real: Homebrew reported stable version 0.5.4, 69 installs in the previous 30 days, and 548 installs in the previous year as of June 30, 2026. Its adoption story is also a lineage story: it exists because Dockerfile formatting remained useful after `dockfmt`, while modern BuildKit syntax, shell formatting expectations, pre-commit workflows, and CI images needed a fresher implementation. ### 使われ方 Users run `dockerfmt Dockerfile` to print formatted output, `dockerfmt -w Dockerfile` to rewrite files, `dockerfmt -c Dockerfile` to check formatting, or pipe Dockerfiles through stdin. It can read EditorConfig properties such as `indent_size` and `insert_final_newline` when formatting files by path. ### パッケージ好きにとっての重要性 dockerfmt is package-nerd significant because formatters become part of project policy. By exposing a Go binary, Docker image, pre-commit hook, and JS/WASM bindings, it tries to make Dockerfile formatting usable from local editors, CI, JavaScript tooling, and ordinary package managers. ### タイムライン - 2025: Repository created and 0.1.0-alpha initial release published. - 2025: 0.2.x releases added JavaScript release work and bug fixes. - 2026: 0.5.4 released and Homebrew formula reports stable 0.5.4. ### Related projects - dockerfmt is directly related to `dockfmt`, Moby BuildKit's Dockerfile parser, and `shfmt`. - It also fits into pre-commit and CI formatting workflows, similar to language-specific formatters such as gofmt and prettier, but for Dockerfiles. ### ソース - - - - - ## セキュリティノート narrow executable package without higher-risk signals. - **Geiger リスク:** グリーン / 低 - narrow executable package without higher-risk signals ## 他のパッケージマネージャ記録 - Nix - dockerfmt: normalized package name match | nixpkgs package indexes: pkgs/by-name/do/dockerfmt/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 ## Combined YAML source View the package source record on GitHub.
