terradart_codegen 0.12.0

terradart Stage 1 codegen — parses Terraform provider schema JSON and Magic Modules YAML and emits annotated abstract Dart classes. Ships the terradart CLI.

terradart_codegen

Codegen for terradart. Parses terraform providers schema -json (plus optional Magic Modules YAML overlays) and emits typed Dart factory wrappers for use with terradart_core.

This package ships the terradart CLI with three subcommands:

• terradart codegen — for any google_* resource that isn't already in terradart_google. Emits annotated abstract Dart classes into your own lib/generated/ directory; you then run build_runner to produce the concrete bindings.
• terradart wrap — used by terradart_google maintainers to regenerate the 28 curated factory wrappers + their schema carriers from YAML overrides under lib/src/codegen/wrapper_overrides/yaml/. Run with --check in CI to verify the wrap output stays byte-identical (deterministic codegen guarantee).
• terradart wrap-promote — scans a curated override yaml against the parsed schema and proposes enum_values blocks + dartTypeOverrides entries for fields whose schema declares a fixed value set. Authors review and integrate manually so naming choices stay with the human.

Installation

terradart_codegen ships the terradart CLI. terradart is a SemVer pre-release, so activate with an explicit version:

dart pub global activate terradart_codegen 0.1.0-dev

(dart pub global activate terradart_codegen without an explicit version skips pre-releases.)

Quickstart: emit bindings for any other resource

# 1. Dump the provider schema.
mkdir schema-dir && cd schema-dir
cat > providers.tf <<'EOF'
terraform {
  required_providers {
    google = { source = "hashicorp/google", version = "~> 7.0" }
  }
}
EOF
terraform init
terraform providers schema -json > schema.json
cd ..

# 2. Run codegen.
terradart codegen \
  --provider hashicorp/google \
  --source schema-dir \
  --output lib/generated

# 3. Run build_runner to produce the concrete bindings.
dart run build_runner build

The --source directory must contain schema.json (output of terraform providers schema -json) and may contain an optional mm/<resource>.yaml overlay subdirectory.
