Flat data structure

As the flat data structure is made up of a root loop of records, only specific portions of a single template file can be scanned for data interpolation.

Each interpolated area of the template is called an injection area and is delimited by a loop templating structure.

Using the CLI, the loop templating structure delimitating an injection area expects the injection-loop-variable argument as a looping variable ( $ by default )

Input file content

terraform {
  required_providers {
    ($)[
      {{name}} = {
        source = "{{namespace}}/{{name}}"
        version = "{{version}}"
      }
    ]
  }
}

Data structure

[
  {
    "namespace": "hashicorp",
    "name": "aws",
    "version": "2.0.1"
  },
  {
    "namespace": "hashicorp",
    "name": "azure",
    "version": "3.4.2"
  },
  {
    "namespace": "hashicorp",
    "name": "google",
    "version": "1.2.1"
  }
]

Result

    required_providers {
        azure = {
            source = 'az/azure'
            version = '1.0.0'
        }
        aws = {
            source = 'aws/aws'
            version = '1.1.0'
        }
