Topic: Roc format on save (VS Code)

How can I setup format on save with VS Code?

If you use the unofficial vscode extension (https://github.com/ivan-demchenko/roc-vscode-unofficial) with LSP configured then something like this works for me:

{
  "roc-lang.language-server.exe": "/path/to/roc_ls",
  "editor.formatOnSave": true,
  "editor.formatOnSaveMode": "file"
}

I tried this, and I believe the LSP is working because I'm getting warnings in my code, but it's still not formatting on save

I also have the Roc (Unofficial) extension installed by Ivan

Does the formatting work at all?
Can you manually format a roc file?
E.g. when you run "command pallete (ctrl/cmd + shift + p)" -> "Format Document"

Thanks, I had prettier set as my formatter, changed it to Roc and now it works :)
