HCLParser

A package to read Terraform 0.12.0 into an elixir manageable data structure.

Usage

# get a string of code, whether its from you or a file

tf_code = '
    resource "google_compute_instance" "test1" {
      name         = "test"
      machine_type = "n1-standard-1"
      zone         = "us-central1-a"
      tags         = ["foo", "bar"]
      allow_stopping_for_update = true
      service_account {
        scopes = ["userinfo-email", "compute-ro", "storage-ro"]
      }
      metadata = {
        foo = "bar"
      }
    }

    resource "google_compute_instance" "test2" {
      name         = "test"
      machine_type = "n1-standard-1"
      zone         = "us-central1-a"
      tags         = ["foo", "bar"]
      allow_stopping_for_update = true
      service_account {
        scopes = ["userinfo-email", "compute-ro", "storage-ro"]
      }
      metadata = {
        foo = "bar"
      }
    }
    '
  HCLParser.parse(tf_code)

  # returns the following:
  ex(2)> HCLParser.parse(tf_code)
HCLParser.parse(tf_code)
{:ok,
 %{
   resource: %{
     "google_compute_instance" => %{
       "test1" => %{
         allow_stopping_for_update: true,
