## Project history and usage

tfplugingen-openapi is HashiCorp's OpenAPI Provider Spec Generator, a CLI that transforms OpenAPI 3.x specifications into Terraform Provider Code Specification files. It belongs to Terraform's provider code-generation toolchain rather than to ordinary Terraform runtime usage.

### Project history

The project was published under the HashiCorp organization as terraform-plugin-codegen-openapi. Its README describes the generator as part of Terraform Provider Code Generation and points to the HashiCorp Developer documentation for full usage, examples, and generator configuration.

HashiCorp documents the generator as a tech-preview code-generation component. The official design document explains how OpenAPI operations, schemas, request bodies, responses, and parameters map into Terraform provider resources, data sources, and schema attributes.

### Adoption history

Adoption is concentrated among Terraform provider authors experimenting with code generation from existing API descriptions. GitHub tags show 0.1.0 through 0.3.0 releases from October 2023 to January 2024, and Homebrew later packaged the tfplugingen-openapi binary for local installation.

### How it is used

The primary command is `tfplugingen-openapi generate`, usually run with a generator_config.yml file, an output path for provider_code_spec.json, and an OpenAPI specification file. The generated provider code specification can then feed the Terraform Plugin Framework code generator.

### Why package nerds care

For package-manager and Terraform-provider specialists, tfplugingen-openapi is significant because it turns API descriptions into provider scaffolding inputs. It packages a slice of HashiCorp's provider-authoring workflow as a standalone Homebrew-installable CLI.

### Timeline

- 2023: GitHub tags list v0.1.0 in October.
- 2024: GitHub tags list v0.3.0 in January.
- 2025: HashiCorp Developer page metadata lists the OpenAPI generator documentation publication/modification date as May 27.
- 2026: Homebrew formula metadata lists stable version 0.3.0 with bottled builds.
