Amba.TfVars 1.1.3

Terraform TfVars files parser and serializer for DotNet C#

This is a simple parser and serializer for Terraform .tfvars files into a tree of nodes. The main purpose is to provide a way to process and transform .tfvars files. It is written in C# and it is based on the ANTLR4 library.

Usage

Parsing

var tfvarsNodes = TfVarsContent.Deserialize("key = value");

Serializing

var tfvarsString = TfVarsContent.Serialize(tfvarsNodes, indentSize: 4);

Tree navigation

const string varfile = """
                           users = [                                
                               {
                                   name = "Jane"
                                   email = "jane@x.com"
                                   meta = {
                                       age = 25
                                   }
                               }
                            ]
                       """;
var parsed = TfVarsContent.Parse(varfile);
Assert.Equal(25, (int)parsed["users"][0]["meta"]["age"]);

Known limitations

• The parser doesn't support comments.
• The parser doesn't do any validation on the content of the tfvars file.
• The serializer does code format which is not the same as terraform fmt does.
• The parser doesn't support multiline strings done with <<EOF syntax.
