Multiple format verbs in conditional not handled correctly

[ewbankkit]

My configuration (hashicorp/terraform-provider-aws#14013) is

cidr_block      = (%[2]q == "cidr_block") ? %[3]q : null
ipv6_cidr_block = (%[2]q == "ipv6_cidr_block") ? %[3]q : null

and terrafmt reports an error

failed to process with: failed to parse hcl: ./aws/resource_aws_route_table_test.go:69,48-49: Unbalanced parentheses; Expected a closing parenthesis to terminate the expression.
...
cidr_block      = (TFFMTKTBRACKETPERCENT[2]q == "cidr_block") ? %[3]q : null
ipv6_cidr_block = (TFFMTKTBRACKETPERCENT[2]q == "ipv6_cidr_block") ? %[3]q : null

This error seems to be in addition to the issue reported in #37.

This can usually be worked around via locals:

locals {
  attr_name  = %[2]q
  attr_value = %[3]q
}

cidr_block      = (local.attr_name == "cidr_block") ? local.attr_value : null
ipv6_cidr_block = (local.attr_name == "ipv6_cidr_block") ? local.attr_value : null

As a workaround until #41 is merged, you might be able to use %q instead of the indexed form %[2]q. The current code for handling formatting verbs doesn't support the indexed form after a (.
