Several [pre-commit](http://pre-commit.com/) hooks to keep Terraform configurations (both `*.tf` and `*.tfvars`) in a good shape:
* `terraform_fmt` - Rewrites all Terraform configuration files to a canonical format.
* `terraform_validate_no_variables` - Validates all Terraform configuration files without checking whether all required variables were set.
* `terraform_validate_with_variables` - Validates all Terraform configuration files and checks whether all required variables were specified.
* `terraform_docs` - Inserts input and output documentation into `README.md`.

## Notes about hooks

1. `terraform_validate_no_variables` and `terraform_validate_with_variables` will not work if variables are being set dynamically (eg, when using [Terragrunt](https://github.com/gruntwork-io/terragrunt)). Use `terragrunt validate` command instead.

1. `terraform_docs` will insert/update documentation generated by [terraform-docs](https://github.com/segmentio/terraform-docs) between markers - `<!-- BEGINNING OF PRE-COMMIT-TERRAFORM DOCS HOOK -->` and `<!-- END OF PRE-COMMIT-TERRAFORM DOCS HOOK -->` if they are present in `README.md`. Make sure that `terraform-docs` is installed.

## Example

`.pre-commit-config.yaml`:

```yaml
- repo: git://github.com/antonbabenko/pre-commit-terraform
  rev: v1.7.3
  hooks:
    - id: terraform_fmt
    - id: terraform_docs
```

Enjoy the clean and documented code!
