How to Use This Documentation

I just want to understand what these libraries do

→ Read EXPLORATION_SUMMARY.md (15-20 minutes)

I know what I need and want quick API reference

→ Check LIBRARIES_QUICK_REFERENCE.md for your specific task (5 minutes)

I want to integrate these into my project

→ Follow the checklist in ZIG_LIBRARIES_GUIDE.md under "Integration Strategy" (1-2 hours)

I want to implement a specific feature

→ Search ZIG_LIBRARIES_GUIDE.md for that library's section (varies)

I'm stuck and need troubleshooting

→ Check the troubleshooting section in LIBRARIES_QUICK_REFERENCE.mdorZIG_LIBRARIES_GUIDE.md

Library Summary at a Glance

Key Concepts

Zero Dependencies

All four libraries depend only on Zig's standard library. No external tools, no version conflicts, minimal binary size.

Type Safety

All four libraries leverage Zig's type system for compile-time validation. Errors caught before runtime.

Production Ready

All libraries are stable, tested, and used in production. No alpha or beta code.

Work Together Seamlessly

The libraries are designed to complement each other. Use all four or pick what you need.

Getting Started

1. Understand the Libraries (20 minutes)

# Read the overview
cat EXPLORATION_SUMMARY.md | less

2. Review Your Project Type

In EXPLORATION_SUMMARY.md, find your project type:

• CLI Tool
• Library/SDK
• Web Service
• Daemon/Background Process

Note which libraries are recommended.

3. Create Integration Plan (30 minutes)

Follow the integration checklist in ZIG_LIBRARIES_GUIDE.md:

• Phase 1: Core Setup
• Phase 2: Testing Infrastructure
• Phase 3: CLI Foundation
• Phase 4: Error Handling
• Phase 5: Documentation

4. Implement (1-2 hours)

Use LIBRARIES_QUICK_REFERENCE.md for API reference while implementing.

5. Document Your Usage (30 minutes)

Document which libraries you're using and create project-specific examples.

Common Integration Patterns

Building a CLI Tool

1. Use zig-cli for command structure
2. Use zig-config for configuration
3. Use zig-error-handling for error handling
4. Use zig-test-framework for testing

Building a Library

1. Use zig-error-handling for API error handling
2. Use zig-test-framework for comprehensive testing
3. Consider zig-config if configuration is needed
4. Skip zig-cli (user's responsibility)

Building a Web Service

1. Use zig-cli for management commands
2. Use zig-config for application configuration
3. Use zig-error-handling for request handling
4. Use zig-test-framework for functional testing

Integration Checklist

Quick checklist to integrate all four libraries:

Phase 1: Setup (30 min)

• Create build.zig.zon with all dependencies
• Update build.zig with imports
• Copy result.zig to src/
• Create config struct in src/config.zig
• Define error types in src/errors.zig

Phase 2: Testing (30 min)

• Create tests/ directory
• Write first *.test.zig file
• Configure zig build test
• Add coverage if desired

Phase 3: CLI (45 min)

• Design command structure
• Implement first type-safe command
• Add interactive prompts
• Integrate config loading

Phase 4: Error Handling (30 min)

• Define custom error types
• Use Result in key functions
• Create error translation layer

Phase 5: Documentation (30 min)

• Document CLI commands
• Provide config examples
• Create testing guide
• Add troubleshooting section

Total Time: ~3 hours for full integration
