## CLI Quick Reference

### Module Management
```bash
go mod init <module>       # Initialize module
go mod tidy                # Sync dependencies
go get <pkg>@latest        # Add/update dependency
go get <pkg>@v1.2.3        # Specific version
go mod download            # Download dependencies
go mod why <pkg>           # Why is pkg needed
go mod graph               # Dependency graph

Build & Run

go build ./...             # Build all packages
go run .                   # Run current package
go install ./cmd/...       # Install binaries
go generate ./...          # Run go:generate directives

Testing

go test ./...              # Run all tests
go test -v ./...           # Verbose output
go test -race ./...        # Race detector
go test -cover ./...       # Coverage summary
go test -coverprofile=c.out ./... && go tool cover -html=c.out  # Coverage HTML
go test -bench=. ./...     # Run benchmarks
go test -fuzz=FuzzXxx ./...  # Fuzz testing
go test -run=TestName      # Run specific test
go test -count=1           # Disable test caching

Linting (golangci-lint)

golangci-lint run          # Run all linters
golangci-lint run --fix    # Auto-fix issues
golangci-lint linters      # List available linters

Workspaces (multi-module)

go work init ./mod1 ./mod2 # Initialize workspace
go work use ./mod3         # Add module to workspace
go work sync               # Sync workspace

Other Tools

go fmt ./...               # Format code
go vet ./...               # Static analysis
go doc <pkg>               # View documentation
go env                     # Environment variables
go version                 # Go version
