SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Go developers often struggle with nil handling and boilerplate error propagation. This Skill introduces monadic abstractions (Option, Result, Either) to model absence, failure, and alternative choices in a type-safe, composable way, reducing nil-pointer risks and repetitive error checks.

Core Features & Use Cases

  • Option for explicit nullable values to prevent nil dereferences and clarify absence in JSON/DB models.
  • Result for ergonomic error handling and composable pipelines within Go code.
  • Either for representing two valid alternatives, such as cached vs fresh data, without signaling errors.
  • Do notation, and pipeline utilities to chain operations with minimal boilerplate.
  • Guidance on using sub-packages (option, result, either) for type-changing transforms and pipes.

Quick Start

Install and try a simple monadic flow: import the mo library, create Some/Ok values, and apply a small Map to observe automatic short-circuiting on None/Err.

FAQPage Schema
How do I handle nullable values in Go without causing nil dereferences?

You can handle nullable values in Go by using the Option monad to explicitly model presence or absence. This prevents nil dereferences by wrapping potentially missing values in a type-safe structure, clarifying absence in JSON and database models.

What is the best way to reduce error propagation boilerplate in Go pipelines?

The best way to reduce error propagation boilerplate is using the Result monad for ergonomic error handling. It enables composable pipelines that automatically short-circuit on errors, minimizing repetitive manual error checks throughout your data flows.

How do I represent two valid alternatives in Go without signaling an error?

You can represent two valid alternatives in Go without signaling an error by using the Either monad. It models mutually exclusive choices like cached versus fresh data, distinguishing between valid states rather than treating one as a failure.

Does the samber/mo library require Go generics for monadic operations?

Yes, the samber/mo library requires Go generics to perform monadic operations. It leverages generics to provide type-safe abstractions for Option, Result, and Either, enabling type-changing transforms and pipeline composition.

How do I chain monadic operations in Go using Do notation?

You can chain monadic operations in Go using Do notation and pipeline utilities to sequence operations with minimal boilerplate. This approach allows you to apply transforms and automatically short-circuit computations when encountering None or Err states.

When should I not use monads for error handling in Go?

You should not use monads for error handling in Go when simple, direct error checks suffice for your use case. Introducing Option, Result, or Either abstractions may add unnecessary complexity for basic logic flows that do not require pipeline composition.
