It occupies a small but practical niche in developer tooling: catching duplicate keys, formatting mistakes, missing values, and other problems in configuration files before an application fails at runtime. ### Project history The project reached a public 1.0.0 release on January 1, 2020, and its README presents the Rust rewrite as the fast successor to an earlier dotenv-linter implementation. The official documentation grew around checks, fix mode, diff mode, installation options, and CI integrations rather than a large application framework. ### Adoption history Adoption has mostly followed the package-manager and CI-tooling route. The project documents GitHub Actions, CircleCI, Super-Linter, reviewdog, pre-commit hooks, and package-manager installation paths, which made it easy to add to existing repositories without changing application code. ### How it is used Developers use dotenv-linter locally or in CI to scan one or more .env files, automatically fix some warnings, or compare .env and .env.example files for missing keys. It is language-agnostic because dotenv files are used across many ecosystems. ### Why package nerds care For package maintainers, dotenv-linter is a compact example of the modern Rust CLI pattern: a single executable, fast startup, prebuilt install script, Homebrew/Nix/APK packaging, and direct CI integration. Its significance is not broad platform history but the way it packages a tiny quality gate as a reproducible CLI tool. ### Timeline - 2020: v1.0.0 was published on GitHub releases. - 2020: v2.x releases added to the project during the broader Rust CLI rewrite period. - 2021: v3.0.0 was published, reflecting continued maintenance of the Rust implementation. ### Related projects - dotenv - reviewdog - pre-commit - GitHub Super-Linter ### Sources - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** dotenv-linter - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - Nix - dotenv-linter: normalized package name match | nixpkgs package indexes: pkgs/by-name/do/dotenv-linter/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - apk - dotenv-linter - 4.0.0-r0: normalized package name match | Alpine Linux edge package indexes: dotenv-linter from https://dl-cdn.alpinelinux.org/alpine/edge/testing/x86_64/APKINDEX.tar.gz | Lightning-fast linter for .env files | https://dotenv-linter.github.io ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [rust](https://www.automicvault.com/pkg/brew/rust/) - Build dependency declared by Homebrew. - [lychee](https://www.automicvault.com/pkg/brew/lychee/) - Shares av.db curated category or tags: cli, developer-tools, quality-assurance, rust. - [ruff](https://www.automicvault.com/pkg/brew/ruff/) - Shares av.db curated category or tags: cli, developer-tools, linter, rust, static-analysis. - [selene](https://www.automicvault.com/pkg/brew/selene/) - Shares av.db curated category or tags: cli, developer-tools, linter, rust, static-analysis. - [statix](https://www.automicvault.com/pkg/brew/statix/) - Shares av.db curated category or tags: cli, developer-tools, linter, rust, static-analysis. - [action-validator](https://www.automicvault.com/pkg/brew/action-validator/) - Shares av.db curated category or tags: cli, developer-tools, linter, rust. - [dscanner](https://www.automicvault.com/pkg/brew/dscanner/) - Shares av.db curated category or tags: cli, developer-tools, linter, static-analysis. - [elvis](https://www.automicvault.com/pkg/brew/elvis/) - Shares av.db curated category or tags: cli, developer-tools, linter, static-analysis. - [errcheck](https://www.automicvault.com/pkg/brew/errcheck/) - Shares av.db curated category or tags: cli, developer-tools, linter, static-analysis. ## Combined YAML source View the package source record on GitHub.
