' Relationships
PluginFactory --> LanguageRegistry : queries configs
PluginFactory --> PluginCacheManager : caches plugins
PluginFactory --> EnhancedPluginLoader : loads enhanced
PluginFactory --> SpecializedPluginLoader : loads specialized
PluginFactory --> DocumentPluginLoader : loads documents
PluginFactory ..> GenericTreeSitterPlugin : creates generic
LanguageRegistry --> LanguageConfig : manages
' External dependencies
PluginFactory ..> IPlugin : creates
PluginFactory ..> SQLiteStore : passes to plugins
}
' Note about supported languages
note bottom of PluginFactory
Supports 48+ languages:
- 6 Enhanced: Python, JS, C, C++, Dart, HTML/CSS
- 7 Specialized: Java, Go, Rust, C#, Swift, Kotlin, TypeScript
- 2 Document: Markdown, PlainText
- 35+ Generic: Ruby, PHP, Scala, Haskell, etc.
Uses lazy loading and caching for performance
