Generated Terraform function signatures

This package can generate function signature files for Terraform >= 1.4 automatically.

It is intended to run whenever HashiCorp releases a new Terraform version. If the Terraform version contains updated function signatures, it generates a new file for that version. When no changes are detected, one should commit the version bump in gen/gen.go.

Pre-releases are accepted with the following caveats:

• The given pre-release version of Terraform is downloaded
• The pre-release part of the version is omitted in all other contexts (e.g. function name, file name, constraint etc.)

... meaning that e.g. 1.5.0-alpha20230504 downloads Terraform 1.5.0-alpha20230504 but assumes compatibility with 1.5.0. Therefore, generating signatures based on pre-releases should be used with the assumption that those signatures won't change before the final release.

Running

Update the terraformVersion in gen/gen.go with the version of the new Terraform release.

Run go generate ./internal/funcs/generated. This command will:

1. Install the specified Terraform version.
2. Run terraform metadata functions -json to obtain the function signatures.
3. Compare a hash of the JSON string to functionSignatureHash in gen/gen.go.
   1. If there are no changes, we will stop here.
4. Create a new Go file with the function signatures of that Terraform version.
5. Regenerate the function signature selection in functions.go.

If everything looks solid, update the functionSignatureHash with the one from the output, and commit all changes.
