Can you try to reinstall it? We recently had someone who thought it got stuck on install and aborted it and it still was callable from path.

Just setup a new machine and having the same issue. elm-format doesn’t run when I save.

I’ve tried uninstalling / reinstalling the VS code plugin
I can run elm-format from the command line
I have a elm.json in the root folder
I also have a elm-tooling.json in the root folder
I’ve open the project folder up in VS code (see my solution previously)
I’ve tried several different .elm files. Same result
I’ve tried setting the Elm Format Path directly

Not sure what else to try.

The Elm output in VS code looks fine. No mention of elm-format, though.

Hey @Razzeee I got it working!

It works when I open the folder of my project, i.e. File -> Open Folder… from VS code. Then I see Elm in the Output window drop-down.

Formatting on save didn’t work at first, but I did see a message saying “Run npm install -g elm-format”. That didn’t work - what did was clearing the Elm Format Path setting that I had set earlier. Now it formats on save! And I have suggestions working too!

Thanks for the help.

It’s on the path, and I’m able to call it manually. Which is formatting the file successfully.
