Retab is a Go-based CLI tool that streamlines configuration management by bridging the gap between HCL's simplicity and YAML/JSON's universality. Retab allows developers to write configurations in a more readable and expressive HCL syntax, while still generating industry-standard output formats. In addition, it exposes its accessible formatting tool so it can be used on any HCL, Terraform, Protocol Buffers, or Dart file.
