Integrating with VSCode

You can get Solidity support for Visual Studio Code by installing the VSCode Solidity extension.

To make the extension play nicely with Foundry, you may have to tweak a couple of things.

1. Remappings

You may want to place your remappings in remappings.txt.

If they are already in foundry.toml, copy them over and use remappings.txt instead. If you just use the autogenerated remappings that Foundry provides, run forge remappings > remappings.txt.

2. Dependencies

You may have to add the following to your .vscode/settings.json for the extension to find your dependencies:

{
  "solidity.packageDefaultDependenciesContractsDirectory": "src",
  "solidity.packageDefaultDependenciesDirectory": "lib"
}

Where src is the source code directory and lib is your dependency directory.

3. Formatter

To enable the built-in formatter that comes with Foundry to automatically format your code on save, you can add the following settings to your .vscode/settings.json:

{
  "editor.formatOnSave": true,
  "[solidity]": {
    "editor.defaultFormatter": "JuanBlanco.solidity" 
  },
  "solidity.formatter": "forge",
}

To configure the formatter settings, refer to the Formatter reference.

4. Solc Version

Finally, it is recommended to specify a Solidity compiler version:

"solidity.compileUsingRemoteVersion": "v0.8.17"

To get Foundry in line with the chosen version, add the following to your default profile in foundry.toml.

solc = "0.8.17"
