Terraform Extra

lang.terraform adds Terraform and HCL support through terraform-ls, with terraform fmt formatting and tflint linting.

Enable it

-- ~/.config/blak/lua/blak/user.lua
return {
  extras = {
    enabled = {
      "lang.terraform",
    },
  },
}

Or enable it interactively:

:BlakExtras enable lang.terraform

What it adds

Surface	Contribution
Treesitter	terraform, hcl
Mason	tflint
LSP	terraformls
Formatting	terraform_fmt for terraform, terraform-vars
Linting	tflint for terraform

terraformls installs automatically through Mason (package terraform-ls).

terraform_fmt shells out to the terraform CLI, which must be on your $PATH. terraform-ls does not serve generic .hcl files (Packer, Nomad), so HCL receives Treesitter highlighting only.

Configure terraform-ls

return {
  extras = { enabled = { "lang.terraform" } },
  lsp = {
    servers = {
      terraformls = {
        settings = {
          terraform = {
            validation = { enableEnhancedValidation = true },
          },
        },
      },
    },
  },
}

Install and verify

:BlakToolsInstall
:BlakTreesitterInstall
:BlakDoctor

Open a .tf file and check :LspInfo for terraform-ls. Ensure the terraform CLI is installed for format-on-save to work.
