add language HCL

[ppenguin]

Terraform doesn't register hcl and doesn't offer good DX if manually set for editing e.g. nomad HCL files.

My first nvf contribution. Maybe somebody could show how to integrate a formatter as well. Other than that it's already an improvement for editing non-Terraform files (e.g. nomad), but it could be probably better. (I vaguely remember the vscode plugin offered some more features).

Looks reasonable. Though, I will need you to format via alejandra and not nixfmt. The formatting check is failing.

Other than that, if there is a known formatter for HCL I can work on getting it added tomorrow. We will need null-ls (or none-ls) to support HCL for proper formatting.

Thanks for looking into it so quickly...

Ah yes, different than nixpkgs :sweat_smile:

While we're at it, is there a trick that I can (e.g. via direnv) use the active HM config for nvf but override certain attributes (like the formatter) in a devshell (when I'm in the nvf repo)? Or would I need to outsource my "standard" nvf config to a separate flake for that?

Looking at none-ls builtins, I see an formatter source for Terraform. This could be used to add formatter support via terraform fmt. Refer to other language modules on how formatter submodules are added - the process is extremely straightforward but I'll be around if you have questions.

Afraid there isn't a way to impurely override configuration per-project, but we do provide a formatter that will format the code for you with nix fmt. I will consider making this a pre-commit hook, or at least have pre-commit warn you before you commit the changes.

I finally got around to finish this one. In hindsight I might have gone a bit overboard with (unnecessary?) extensibility (inspired by the bash setup), but given the fact that terraform-ls is a bit too generic for nomad, there may be more specific solutions in the future that we might then easily integrate.

EDIT: spelling (noticed spelling "funture", I might be on to something :rofl )
