Is it possible to configure VSCode to run forge fmt on save?

[PaulRBerg]

The Foundry Book documents the forge fmt command here, but it doesn't give any indication for how to configure it to automatically format on Save in VSCode.

What would one typically do to enable format on save in VSCode is add the following settings:

{
  "editor.formatOnSave": true,
  "[solidity]": {
    "editor.defaultFormatter": "esbenp.prettier-vscode" 
  }

The trouble is that the defaultFormatter setting expects the name of an extension, but there isn't any bespoke Foundry VSCode extension at the moment. So it seems to be that it is not currently possible to format on save with forge fmt in VSCode - but I opened this discussion to make sure that my understanding is correct?

I am not sure if it possible to go around this limitation with tasks. It's definitely possible to add a task for running forge fmt, but that wouldn't help much because the user would have to remember to run the task by themselves.

It looks like Juan Blanco's vscode-solidity extension has support for forge fmt. @shekhirin added support for Forge in this PR, and the configuration is as simple as adding this to your VSCode settings:

"solidity.formatter": "forge"

This is not documented anywhere, however. I will a PR in the Foundry Book repo to document the set-up.

You can also do this with the hardhat VSCode extension, which personally I prefer as it seems to work better in pure foundry projects

Oh, nice!
