lifecycle Examples

This folder contains runnable examples demonstrating various features of the lifecycle library.

Basic Patterns (CLI & Automation)

These examples demonstrate the core "Death Management" features (v1.0-v1.4). Ideal for CLIs, Scripts, and simple Tools.

• basic: The "Hello World" of lifecycle. Shows Run, Go, and Job.
• context: Manual setup via lifecycle.Context() for gradual migration.
• hooks: How to register and execute synchronous/asynchronous cleanup hooks.
• interactive_dx: Safe reading from Stdin (Windows CONIN$ support) that respects context cancellation.

Advanced Patterns (Control Plane v1.5+)

These examples demonstrate "Life Management" capabilities (v1.5+). Ideal for Services, Daemons, and Agents.

• suspend: The full Control Plane experience. Shows Supervisors, Suspend/Resume events, and Durable Execution.
• supervisor: Managing a tree of child processes/workers with restart policies.
• repl: Building an interactive REPL that handles signals and custom commands.

Recipes

Specific solutions to common problems.

• zombie: Demonstrating Process Hygiene (Job Objects / PDeathSig) to ensure child processes die with the parent.
• reliability: Using lifecycle.Do for safe execution.
• observability: Visualizing the system state with Mermaid.
