Terraform Configuration Files

resource "aws_s3_bucket" "somesite" {
  region = "${local.region}"
  bucket = "somesite-com"
  acl    = "public-read"
  website {
    index_document = "index.html"
    //    error_document = "error.html"
  }
  policy = <<POLICY
{
  "Version":"2012-10-17",
  "Statement":[{
	"Sid":"PublicReadGetObject",
      "Effect":"Allow",
	  "Principal": "*",
      "Action":["s3:GetObject"],
      "Resource":["arn:aws:s3:::somesite-com/*"]
    }
  ]
}POLICY

}

output "somesite_website_endpoint" {
  value = "${aws_s3_bucket.somesite.website_endpoint}"
}

Expected Behavior

What should have happened?

The output block at the bottom of the config should be formatted correctly. If I move it about the resource block (eg before the heredoc block) it is formatted correctly.

Actual Behavior

What actually happened?

Steps to Reproduce

Please list the steps required to reproduce the issue, for example:

Create config with a <<EOF...EOF block that also has additional config after it, the config after won't be formatted correctly.

Interesting that the github code formatting has the same formatting problem.

I think the problem here is that second POLICY should start on newline, not after some characters. Even highlighting shows that.
Proper heredoc use:

a = <<POLICY
{
}
POLICY

Ahh, thanks, that works.

However it seems to be valid syntax without the new line, as far as terraform is concerned (it runs it without complaining), and terraform fmt doesn't correct it. Happy to close though.

That was actually a bug in hcl parser itself, resolved in hashicorp/hcl#245
AFAIU future versions of Terraform would not support that syntax as it contradicts usual 'heredoc' definition used in bash, etc.
