Documentation Generation

Project KARL includes comprehensive documentation generation using Dokka. The documentation covers all public APIs, includes code examples, and provides detailed technical explanations.

Quick Start

Generate Documentation

./gradlew generateDocs

Open Documentation in Browser

./gradlew openDocs

Clean Documentation

./gradlew cleanDocs

Available Documentation Formats

  • HTML Multi-Module: Complete documentation with cross-module linking
  • Individual Module Docs: Per-module documentation available via ./gradlew :module-name:dokkaHtml

Module Documentation

KARL Core

Contains fundamental interfaces, data models, and APIs for the KARL framework.

  • Core interfaces: LearningEngine, KarlContainer, DataStorage, DataSource
  • Data models: InteractionData, KarlContainerState, Prediction, KarlInstruction
  • API layer: Karl builder pattern and configuration utilities

KARL KotlinDL Engine

Machine learning implementation using KotlinDL for neural network computation.

  • KLDLLearningEngine: Main ML engine with incremental learning
  • SimpleMLPModel: Multi-layer perceptron architecture
  • Privacy-first on-device training and inference

KARL Room Storage

Robust data persistence layer using Android's Room database library.

  • RoomDataStorage: Main storage implementation
  • KarlDao: Type-safe database operations
  • Entity models for container state and interaction data

KARL Compose UI

Modern UI components for visualizing KARL AI containers.

  • KarlContainerUI: Main container visualization
  • KarlLearningProgressIndicator: Progress visualization
  • Material Design compliant with reactive state management

Documentation Features

Comprehensive Coverage

  • API Documentation: All public classes, interfaces, and methods
  • Code Examples: Usage patterns and integration examples
  • Architecture Guides: Design principles and implementation details
  • Cross-References: Links between related components

Technical Depth

  • Performance Considerations: Optimization notes and best practices
  • Error Handling: Exception documentation and recovery strategies
  • Thread Safety: Concurrency patterns and safety guarantees
  • Privacy & Security: Data protection and compliance considerations

Developer Experience

  • Source Links: Direct links to GitHub source code
  • External Links: Links to related documentation (Coroutines, Compose, Room)
  • Search Functionality: Full-text search across all documentation
  • Mobile Responsive: Documentation works on all devices

Customization

Module Configuration

Each module includes its own Dokka configuration in build.gradle.kts:

  • Module name and version
  • Source links to GitHub
  • External documentation links
  • Package-level documentation

Adding Documentation

  1. KDoc Comments: Use /** */ format for all public APIs
  2. Module Descriptions: Update Module.md files for module overviews
  3. Code Examples: Include usage examples in KDoc
  4. Cross-References: Use @see tags for related components

External Links

The documentation includes links to:

Build Integration

Gradle Tasks

  • generateDocs: Generate complete multi-module documentation
  • openDocs: Generate and open documentation in browser
  • cleanDocs: Clean generated documentation
  • dokkaHtmlMultiModule: Core Dokka multi-module task
  • :module:dokkaHtml: Generate documentation for specific module

CI/CD Integration

Documentation can be automatically generated and deployed:

- name: Generate Documentation
  run: ./gradlew generateDocs

- name: Deploy Documentation
  # Deploy build/dokka/htmlMultiModule/ to documentation hosting

Quality Assurance

Documentation Standards

  • All public APIs must have KDoc comments
  • Include parameter descriptions with @param
  • Document return values with @return
  • List exceptions with @throws
  • Provide usage examples for complex APIs

Validation

Documentation generation serves as validation:

  • Ensures all KDoc is syntactically correct
  • Verifies cross-references are valid
  • Confirms external links are accessible
  • Tests code examples for compilation

The comprehensive documentation ensures Project KARL is accessible to developers at all levels, from quick integration to deep customization.
