# gopls LSP Go language server integration providing comprehensive code intelligence through gopls (the official Go language server). ## Capabilities - **Code intelligence**: Autocomplete, go-to-definition, find references - **Error detection**: Real-time diagnostics for compilation errors and issues - **Refactoring**: Rename symbols, extract function, organize imports - **Analysis**: Static analysis, code suggestions, unused code detection - **Supported extensions**: `.go` ## Installation Install gopls using the Go toolchain: ```bash go install golang.org/x/tools/gopls@latest ``` **Important**: Make sure `$GOPATH/bin` (or `$HOME/go/bin`) is in your PATH. Verify installation: ```bash gopls version ``` ## Usage The language server runs automatically in LSP-compatible editors. For manual operations: ### Format code ```bash gofmt -w file.go ``` ### Run linter ```bash go vet ./... ``` ### Build and test ```bash go build ./... go test ./... ``` ## Configuration Create `gopls.yaml` in your project or workspace for custom settings: ```yaml analyses: unusedparams: true shadow: true completeUnimported: true staticcheck: true ``` Or configure via environment: ```bash export GOPLS_CONFIG='{"staticcheck": true, "analyses": {"unusedparams": true}}' ``` ## Integration Pattern When editing Go code: 1. gopls provides real-time diagnostics in LSP editors 2. Run `go fmt` or `gofmt` to format code 3. Use `go vet` for additional static analysis 4. Run tests with `go test` before committing ## Common Go Commands - `go mod init <module>` - Initialize Go module - `go mod tidy` - Clean up dependencies - `go get <package>` - Add dependency - `go build` - Compile packages - `go run main.go` - Run program - `go test` - Run tests - `go vet` - Report suspicious constructs ## More Information - [gopls Documentation](https://pkg.go.dev/golang.org/x/tools/gopls) - [GitHub Repository](https://github.com/golang/tools/tree/master/gopls) - [Go Official Documentation](https://go.dev/doc/)
