Are multiline lists valid in Terraform?

Question

I currently have the following.

module "module-name" {
  source                              = "./directory"
  environment                         = var.environment
  team_names                          = ["team-a", "team-b", "team-c", "team-d"]

This clearly makes the team_names line very long. Is it valid to change to this?

module "module-name" {
  source                              = "./directory"
  environment                         = var.environment
  team_names                          = [
                                          "team-a",
                                          "team-b",
                                          "team-c",
                                          "team-d"
                                        ]

Answer 1

Yes. According to Types and Values: Lists/Tuples

List literals can be split into multiple lines for readability, but always require a comma between values. A comma after the final value is allowed, but not required. Values in a list can be arbitrary expressions.
