From 0b51ce4f56dbf769666d5fcce60773dfc7eeae0e Mon Sep 17 00:00:00 2001 From: Hossihub Date: Thu, 23 Apr 2026 08:54:45 +0200 Subject: [PATCH] feat: comprehensive Android/Kotlin navigation and analysis improvements - Complete Jetpack Compose Navigation XML parser (res/navigation/*.xml) - Kotlin DSL navigation support: composable(route), navigation(), argument() - Fragment-based navigation extractor with regex pattern matching - Android TV / Leanback navigation support - Navigation relationship types: nav_action, requires_arg, deep_link, navigates_to - Deep annotation extractor with metadata (annotation_entry, annotation_name, arguments) - Room database extractor (@Entity, @Dao, @Database detection) - Hilt dependency injection component graph extraction - Android resource reference linking (R.id, R.layout, R.string) - ViewBinding and synthetic imports detection - Gradle build system parsing (multi-module dependencies) - Function modifiers: suspend, inline, operator, infix, extension, receiver_type - Class kinds: data, sealed, abstract, open, object, companion - Type parameters and generics - Scope function tagging in call graphs (let, run, apply, with, etc.) - Extension function detection and resolution - Multi-language call graph builder with confidence scoring - Kotlin scope function awareness (confidence 0.3) - Extension function call resolution - Cross-file call resolution with unresolved symbol tracking - Support for Go, TypeScript, Python, Rust, Java, Kotlin, Bash, Ruby, PHP, Elixir, R, Perl - get_nav_graph: Query navigation destinations, actions, arguments - find_route: Resolve route strings and action IDs - get_screen_args: List destination arguments with types - get_nav_callers: Find all navigation call sites - search_annotations: Find code by annotation type - Existing tools now work uniformly across all languages - Parallel and sync indexer paths for performance - XML layout extractor for Android layouts - Terraform configuration parser - CI/CD YAML detection and parsing - Maven and Gradle dependency management - Cicd yaml framework detection - Navigation elements: nav_graph, nav_destination, nav_argument, nav_action, nav_deep_link - Relationship types: 30+ types covering imports, calls, tests, annotations, navigation - Business logic traceability (code-to-requirements linking) - Metadata support for confidence scores and element-specific attributes - Integration tests for Android navigation parsing - Performance benchmarks for indexing operations - Fixture files for Android XML, Kotlin patterns, complex scenarios - Android support documentation and query examples - Fixed nav tool schema mismatches - Removed dead code from navigation pipeline - Proper error handling for malformed XML/Kotlin - Consistent qualified name schemes across all languages --- .opencode/package-lock.json | 20 +- AGENTS.md | 6 +- Cargo.lock | 7 + Cargo.toml | 1 + docs/android-kotlin-xml-improvements.md | 211 ++
