terraform fmt formatting comments block comments using #

[nateww]

Using terraform 0.8.4, terraform formats comment block using # signs by placing newlines between every line. IMO, it shoudn't even be adding a newline after a comment starting with a #, let alone a newline between every line.

Original (pre-fmt)

variable "environment" {
  default = {}

  # default {
  #    "region" = "us-west-2"
  #    "sg"     = "playground"
  #    "env"    = "prod"
  #  }
}

Post-fmt

variable "environment" {
  default = {}

  # default {

  #    "region" = "us-west-2"

  #    "sg"     = "playground"

  #    "env"    = "prod"

  #  }
}

The format of adding a newline after a comment block seem arbitrary.

I am seeing the same thing with terraform 0.8.2. Seems to be happen inside variable blocks.

Original:

# Above Foo 1
# Above Foo 2
variable "foo" {
  # In Foo 1
  # In Foo 2

  default = ""
}

Post-fmt:

# Above Foo comment 1
# Above Foo comment 2
variable "foo" {
  # In Foo Line 1

  # In Foo Line 2

  default = ""
}

I'm seeing a variation; it's eating the first comment.

Pre-fmt:

  vpc_security_group_ids = ["sg-aaaaaaaa", # SG_USE1_DEV_REM_ACC_V01
    "sg-bbbbbbbb",                             # SG_USE1_DEV_REL_MGMT_V01
    "sg-cccccccc",                             # SG_USE1_DEV_INF_MGMT_V01
    "${aws_security_group.docs-us-east-1.id}",
  ]

Post-fmt:

  vpc_security_group_ids = ["sg-aaaaaaaa",
    "sg-bbbbbbbb",                             # SG_USE1_DEV_REL_MGMT_V01
    "sg-cccccccc",                             # SG_USE1_DEV_INF_MGMT_V01
    "${aws_security_group.docs-us-east-1.id}",
  ]

Interesting; it doesn't eat the comment if the first sg-id is on its own line instead of against the opening left bracket.

Pre-fmt:

  vpc_security_group_ids = [
"sg-aaaaaaaa",                             # SG_USE1_DEV_REM_ACC_V01
    "sg-bbbbbbbb",                             # SG_USE1_DEV_REL_MGMT_V01
    "sg-cccccccc",                             # SG_USE1_DEV_INF_MGMT_V01
    "${aws_security_group.docs-us-east-1.id}",
  ]

Post-fmt:

  vpc_security_group_ids = [
    "sg-aaaaaaaa",                             # SG_USE1_DEV_REM_ACC_V01
    "sg-bbbbbbbb",                             # SG_USE1_DEV_REL_MGMT_V01
    "sg-cccccccc",                             # SG_USE1_DEV_INF_MGMT_V01
    "${aws_security_group.docs-us-east-1.id}",
  ]

Fixed! Will be in 0.8.5. @rkulagowski I'm taking a look at that, too.

[nateww]

Thanks, looking forward to 0.8.5

There still appear to be issues with this. v0.11.11 turns

    cidr_blocks = [
      "${var.cidr_blocks}",
      "x.x.x.x/32" # GitHub
    ]

into

    cidr_blocks = [
      "${var.cidr_blocks}",
      "x.x.x.x/32",
    ] # GitHub

and

  # No credentials explicitly set here because they come from either the
