## Project history and usage

dotenv-linter is a Rust command-line linter for dotenv-style .env files. 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.
