Splat operators lead to invalid type

[archoversight]

Using an input file such as:

output "sometest" { value = {
  name = module.instance.*.tags.Name
  id   = module.instance.*.id
} }

When attempting to read it, will lead to this error:

Error: invalid type: string ".*", expected unit

The splat operator is used heavily in our terraform configuration for outputs.

As a follow-up this is also an issue with the [*] splat variant:

output "sometest" { value = {
  name = module.instance[*].tags.Name
  id   = module.instance[*].id
} }

Unable to process: invalid type: string "[*]", expected unit

Hi, this looks like a bug in the deserializer implementation for the traversal operator. It should be fairly easy to fix, i'll try to provide a fix later today.

This should not happen if you use hcl::parse instead of hcl::from_str though.

@archoversight I just published https://crates.io/crates/hcl-rs/0.8.4 which includes the fix.

@martinohmann thank you!

I was using hcl::from_reader() so that I can pass it a file that was opened. Is there a better pattern to use?
