  • The problem is that there's no such thing as HCL itself. Learning the HCL for Terraform is not the same as learning the HCL for Nomad or Packer or even something like https://github.com/ariga/atlas. HCL is a language platform, really, and it has a few key differences from something like JSON that make it more human-readable. In fact, the current version of HCL is designed to be extremely flexible. There are lots of places where things like quotes are optional, and identifiers used to need interpolation even for basic assignment. There isn't really any way to learn HCL independent of Terraform.
