Solidity Language Server

The fastest Solidity language server — go-to-definition, references, rename, completions, hover, and more. See benchmarks.

Install

cargo install solidity-language-server

Or download a pre-built binary from the latest release.

Features

Go to Definition / Go to Declaration — jump to any symbol across files
Find References — all usages of a symbol across the project
Rename — project-wide symbol rename with prepare support
Hover — signatures, NatSpec docs, function/error/event selectors, @inheritdoc resolution
Completions — scope-aware with two modes (fast cache vs full recomputation)
Document Links — clickable imports, type names, function calls
Document Symbols / Workspace Symbols — outline and search
Formatting — via forge fmt
Diagnostics — from solc and forge lint

See FEATURES.md for the full LSP feature set and roadmap.
