## Historique du projet et usages

cfn-format is the Homebrew-packaged command built from the AWS CloudFormation rain repository's `cmd/cfn-format`, focused on checking and formatting AWS CloudFormation templates.

### Historique du projet

The upstream rain repository was created in 2019 and describes rain as a development workflow tool for AWS CloudFormation templates and stacks. Its README lists consistent formatting of CloudFormation templates as a key feature of `rain fmt`, including JSON/YAML conversion and YAML comment preservation.

### Historique d'adoption

Homebrew packages `cfn-format` separately from rain, building the `./cmd/cfn-format` target from the rain source repository. This gives package users a narrower formatter binary without installing the broader rain workflow CLI name.

### Modes d'utilisation

The Homebrew formula test runs `cfn-format -v test.template` and expects a formatted-ok message. The rain README documents the broader formatter behavior under `rain fmt`.

### Pourquoi les passionnés de paquets s'y intéressent

cfn-format is package-nerd-interesting because it exposes one subcommand-sized slice of a larger CloudFormation workflow tool as its own formula, the kind of tiny binary split that helps scripts depend on exactly the formatter they need.

### Chronologie

- 2019: rain GitHub repository metadata records public repository creation.
- 2019: GitHub release metadata records rain v0.1.0.
- 2026: Homebrew formula builds cfn-format from rain v1.24.4.

### Related projects

- rain is the upstream project and broader CloudFormation workflow CLI.
- cfn-flip is the older AWS Labs converter whose CLI usage now points users to `rain fmt`.
