Foundry Book

Integrating with VSCode

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

To make the extension play nice with Foundry, you will need 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.

If you use a non-standard project layout, you may have to add the following to your .vscode/settings.json:

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

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

It is also recommended to specify a Solidity compiler version:

"solidity.compileUsingRemoteVersion": "v0.8.10"

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

solc_version = "0.8.10"
