Anything Else?

I am posting here as it seems that vscode hcl is not very active.

I have both extensions terraform and hcl installed on VSCode and I would like both terraform and terragrunt files to be auto-formatted on save but *.hcl files don't work at all. This is my VSCode settings.

"files.associations": {
  "*.hcl": "hcl",
  "*.tf": "terraform",
},
"[hcl]": {
  "editor.tabSize": 2,
  "editor.defaultFormatter": "hashicorp.hcl",
  "editor.formatOnSave": true
},
"[terraform]": {
  "editor.tabSize": 2,
  "editor.defaultFormatter": "hashicorp.terraform",
  "editor.formatOnSave": true
},

Hi @evertonspader-tomtom, the vscode-hcl extension does not provide a formatting feature for HCL files, so it will not be able to format any kind of HCL files. It only provides syntax highlighting, as described in the README. There is an existing issue asking for formatting support, which explains the complexity and reason it is not supported yet: hashicorp/vscode-hcl#98

The vscode-terraform extension provides a formatter for that is already configured out of the box to format *.tf files. You do not need to set file associations inside your settings, as both the HashiCorp HCL and Terraform extensions automatically configure those at runtime.

Terragrunt files are a separate product, so you will have to look to product for formatting support. The vscode-hcl extension can provide syntax highlighting for any HCL compliant file, but product specific features like Terragrunt require specific support by those products.
