solidity-analyzer

This extension provides Solidity language support for Foundry projects by running the solidity-analyzer language server.

solidity-analyzer is a Solidity language server implementation with first-class Foundry support. A VS Code extension is provided for easy setup, while you can use it with any editor that supports the Language Server Protocol (LSP).

The architecture of solidity-analyzer is structured as a set of libraries for analyzing Solidity code. It's heavily inspired by rust-analyzer, the popular Rust language server.

Features

solidity-analyzer provides IDE features for Solidity development, including:

• diagnostics for real-time error and warning reporting
• go to definition, references, and renaming
• code completion
• hover and signature help
• document and workspace symbols
• formatting and linting
• code actions for quick fixes
• workspace awareness for Foundry projects

Quick start

1. Install Foundry: https://getfoundry.sh/introduction/installation/
2. Install the extension (VS Code 1.93+ required).
3. Open a Foundry workspace (contains foundry.toml or remappings.txt) in VS Code. The bundled server starts automatically.
4. If the configured solc is missing, accept the prompt to install it via Foundry.

Windows Support

Windows support is currently not tested and can be buggy and incomplete. I decided to focus on Unix-like OSes (Linux and macOS) first because I don't have a Windows machine for testing. Pull requests to improve Windows support are welcome.

Configuration

All settings live under solidity-analyzer.*.

Use a custom language server binary:

{
    "solidity-analyzer.server.path": "/path/to/solidity-analyzer"
}
