wizard

tinywasm/wizard

A modular, pluggable wizard orchestrator for TinyGo applications.

LLM Context / Core Logic

The library orchestrates a sequence of Step interfaces. It manages state via tinywasm/context and handles flow control through a completion callback.

Interfaces

type Step interface {
    Label() string                                                                 // Prompt text
    DefaultValue(ctx *context.Context) string                                     // UI Suggestion
    OnInput(in string, ctx *context.Context) (*context.Context, bool, error)      // Logic + next state
}

Flow Control

• New(onComplete func(), steps ...Step): Initializes orchestration.
• Change(input): Executes OnInput for the current step.
• continueFlow (bool): If true, the wizard proceeds even if error != nil (soft failure). If false, it stays on the same step (hard failure).

Features

• Zero dynamic allocations (fixed capacity context).
• Duck-typing compatible: Designed to be implemented by external modules without direct package dependencies.
• TUI-ready: Implements Handler and Loggable patterns.
