Allow controlling aspects of the automatic formatting

With “format on save” enabled, this extension formats in a way that I find quite unpleasant:

resource "aws_ecr_repository" "repo" {
  name                 = "repo"
  image_tag_mutability = "IMMUTABLE"
}

I would much prefer this:

resource "aws_ecr_repository" "repo" {
  name = "repo"
  image_tag_mutability = "IMMUTABLE"
}

Is there any way to adjust this, and if not, could some basic formatting knobs be added?

Hi @jbg What you see here is the intended behavior of terraform fmt. Specifically, the alignment of equals signs only happens for consecutive runs of single-line arguments. Multi-line arguments are considered to be an entirely separate “group” (with only one item) for alignment purposes, because the benefit of easily scanning over the values doesn’t apply when the value itself isn’t positioned relative to the equals sign anyway.

As with all of the terraform fmt formatting decisions, this is a subjective and therefore essentially arbitrary decision based on tradeoffs made by the original implementer, and it’s unlikely to change because that would cause changes for everyone who had previously formatted examples like this with terraform fmt in earlier versions. The bar for changes to existing terraform fmt layout behaviors is very high, and would typically need to have a strong and objective (rather than subjective) justification to warrant causing diffs for all existing Terraform configurations after upgrading.
