Code Actions

The Terraform Language Server implements a set of Code Actions which perform different actions on the current document. These commands are typically code fixes to either refactor code, fix problems or to beautify/refactor code.

Available Actions

source.formatAll.terraform

The server will format a given document according to Terraform formatting conventions.

Usage

VS Code

To enable the format code action globally, set source.formatAll.terraform to true for the editor.codeActionsOnSave setting and set editor.formatOnSave to false.

"editor.formatOnSave": false,
"editor.codeActionsOnSave": {
  "source.formatAll.terraform": true
},
"[terraform]": {
  "editor.defaultFormatter": "hashicorp.terraform",
}

Important: Disable editor.formatOnSave if you are using source.formatAll.terraform in editor.codeActionsOnSave. The source.formatAll.terraform code action is is meant to be used instead of editor.formatOnSave, as it provides a guarantee of order of execution based on the list provided. If you have both settings enabled, then your document will be formatted twice.

If you would like editor.formatOnSave to be true for other extensions but false for the Terraform extension, you can configure your settings as follows:

"editor.formatOnSave": true,
"editor.codeActionsOnSave": {
  "source.formatAll.terraform": true
},
"[terraform]": {
  "editor.defaultFormatter": "hashicorp.terraform",
  "editor.formatOnSave": false,
},

Alternatively, you can include all terraform related Code Actions inside the language specific setting if you prefer:

"editor.formatOnSave": true,
"[terraform]": {
  "editor.defaultFormatter": "hashicorp.terraform",
  "editor.formatOnSave": false,
  "editor.codeActionsOnSave": {
    "source.formatAll.terraform": true
  },
},
