nim-error-handling

What problem does it solve?

It solves the problem of unpredictable or poorly communicated failure behavior in Nim programs by enforcing consistent error boundaries, propagation, and context-rich translation of low-level errors.

Core Features & Use Cases

• Error propagation instead of ad-hoc wrappers: Avoids unnecessary result objects that only carry ok/kind/message and encourages raising and letting errors bubble to the boundary where they become actionable.
• Boundary translation with actionable messages: Converts low-level exceptions at module boundaries to uphold contracts and provide clear, bounded context for callers.
• Parse and helper-specific handling: Implements safe parse-helper patterns, including catching CatchableError once at the helper boundary and returning false for boolean parse helpers.

Quick Start

Ask the AI to refactor your Nim code to use exception propagation across internal steps, translate errors only at module boundaries with context, and implement parse helpers that return false on catchable parse failures.
