The article introduces 'deadcode,' a tool designed to help Go developers identify unreachable functions in their projects. Dead code adds unnecessary complexity to code maintenance. An example from gopls illustrates how a refactor effort may leave functions like 'goodbye' unreachable despite being technically required by interface contracts. Detecting such code earlier can streamline the development process. The 'deadcode' command offers a straightforward usage for detecting these unreachable functions, helping maintain cleaner and more efficient codebases.
Dead code refers to functions in source code that can't be reached during execution, complicating maintenance. A new tool, 'deadcode,' helps identify such functions.
Over time, our adjustments to gopls revealed unreachable callers. Refactoring would have been simpler if we'd known about dead code before making changes.
