x-errors

What problem does it solve?

It helps you standardize local Go error wording and handling so your code stays predictable, readable, and consistent across features.

Core Features & Use Cases

• English, lowercase error messages: Keeps error strings uniform and easy to scan in logs and tests.
• Use %q for string values: Produces correctly quoted diagnostics for safer, more readable message formatting.
• Avoid exported sentinel errors by default: Encourages internal sentinels or typed errors with errors.Is/As to reduce coupling and improve maintainability.

Quick Start

When you’re adding or reviewing a Go function, ask to rewrite its error messages to follow x-errors rules and ensure string formatting uses %q while suggesting a better sentinel/typed-error approach.
