§Configuration Management

This module provides comprehensive configuration management for the Air daemon, serving as the central configuration layer for the entire Land ecosystem.

§Responsibilities

  • Configuration Loading: Load and parse configuration from TOML files with fallback to defaults
  • Schema Validation: Validate all configuration values against defined schemas with detailed error messages
  • Type Safety: Strong typing with compile-time guarantees and runtime validation
  • Value Constraints: Range validation, path validation, and security checks
  • Environment Integration: Support environment variable overrides and profile-based configuration
  • Hot Reload: Live configuration updates without service restart (via HotReload module)
  • Change Tracking: Audit trail for all configuration changes with rollback support
  • Migration Support: Automated configuration schema versioning and migration

§VSCode Configuration System References

This configuration system is designed to be compatible with VSCode’s configuration architecture:

  • VSCode config reference: Dependency/Microsoft/Editor/src/vs/platform/configuration/
  • Format compatibility with settings.json schema structure
  • Support for workspace-specific overrides similar to VSCode’s multi-layer config
  • Configuration inheritance and overriding patterns aligned with VSCode

§Connection to Mountain’s Configuration Needs

Mountain (the VSCode application layer) consumes Air’s configuration:

  • User settings in Mountain flow through to Air’s daemon configuration
  • Wind services read centralized configuration for consistency
  • Configuration changes propagate through the hot-reload system to all services
  • Profile switching (dev/staging/prod) affects entire Land ecosystem

§Configuration Flow

Mountain (User Settings) → Air config file → Wind services
↓ ↓ ↓
settings.json ~/.Air/config.toml Service-specific overrides
↓ ↓ ↓
Workspace settings Environment variables Hot-reload notifications

§TODO: Schema Validation

  • Implement JSON Schema generation for validation
  • Add schema versioning and migration support
  • Provide schema validation errors with detailed field-level information
  • Support schema evolution with backward compatibility

§TODO: Configuration Migration

  • Add version field to configuration structure
  • Implement automatic migration between schema versions
  • Provide migration tools for manual upgrades
  • Document migration paths and breaking changes

§TODO: Configuration Inheritance

  • Implement base profile templates
  • Support profile inheritance and overrides
  • Add configuration layer merging logic
  • Document precedence rules (defaults → file → env → runtime)

§Profiles and Environments

Configuration supports multiple profiles for different deployment scenarios:

  • dev: Development environment with debug logging
  • staging: Pre-production with production-like settings
  • prod: Production optimized settings
  • custom: User-defined profiles

§Security Considerations

  • Path validation prevents directory traversal attacks
  • Sensitive values support environment variable injection
  • Configuration files enforce proper permissions
  • Atomic updates prevent partial/corrupted state
