## プロジェクトの歴史と使われ方

Terraform Landscape is Coinbase's Ruby CLI for reformatting `terraform plan` output into a more readable command-line diff.

### プロジェクトの歴史

Coinbase created the repository in February 2017 and described the tool as a way to make Terraform plan output easier to read and understand. The README shows before-and-after screenshots and documents a simple Unix pipeline: pipe `terraform plan` output into `landscape`.

The project was distributed primarily as the `terraform_landscape` RubyGem with a `landscape` executable, and the README also documents Homebrew installation. Later releases reached v0.3.4 in 2021, while the README still notes Terraform 0.11.x as its expected Terraform version.

### 採用の歴史

Terraform Landscape found adoption among users reviewing Terraform plans in terminals and CI logs, especially before Terraform's own plan UI and ecosystem tooling matured. Its Homebrew formula and RubyGem packaging made it easy to insert into local workflows without changing Terraform itself.

Current Homebrew install counts are low, and the Terraform 0.11.x requirement marks it as more of a legacy plan-formatting tool than a modern Terraform workflow default.

### 使われ方

The documented usage is intentionally small: run `terraform plan ... | landscape`, or pipe plan output into a Docker image built from the repository. That simplicity made it friendly to shell pipelines, CI jobs, and package-manager installation.

### パッケージ好きにとっての重要性

For package nerds, Terraform Landscape is a good example of a tiny formatter with several distribution surfaces: RubyGems for the executable, Homebrew for macOS users, and Docker for isolated command-line use.

### タイムライン

- 2017: GitHub repository created by Coinbase.
- 2019: v0.3.0 series releases published.
- 2021: v0.3.4 released, the version packaged by Homebrew.

### Related projects

- Terraform is the source of the plan output consumed by Landscape.
- RubyGems and Homebrew are the documented package channels.
