Zed OpenTofu

An OpenTofu extension for Zed. Forked and adapted from the official Terraform extension.

Installation and language server resolution

The extension resolves tofu-ls in this order:

  1. A tofu-ls binary already available on your PATH
  2. A previously downloaded tofu-ls binary cached by the extension
  3. The latest compatible tofu-ls release from GitHub

This means the extension now works offline after tofu-ls has been installed once, either manually on your PATH or by letting Zed download it while online.

A first-time install still requires internet access unless you already have tofu-ls installed yourself.

File association conflicts

In order to automatically use the OpenTofu extension and language server when editing .tf, .tofu, and .tfvars files, either uninstall the Terraform extension or add this to your settings.json:

"file_types": {
  "OpenTofu": ["tf", "tofu"],
  "OpenTofu Vars": ["tfvars"]
},

Configuration

The extension forwards Zed LSP settings to tofu-ls under lsp.tofu-ls.settings.

Example:

"lsp": {
  "tofu-ls": {
    "settings": {
      "tofu": {
        "path": "/usr/local/bin/tofu",
        "timeout": "30s"
      },
      "indexing": {
        "ignoreDirectoryNames": ["vendor"]
      }
    }
  }
},
