Features

  • Dual-Strategy Architecture: Specialized tree-sitter parsing for 10 core languages, fallback strategy for 50+ file types

  • Direct Tree-sitter Integration: No regex fallbacks for specialized languages - fail fast with clear errors

  • Advanced Search: Auto-detects and uses the best available tool (ugrep, ripgrep, ag, or grep)

  • Universal File Support: Comprehensive coverage from advanced AST parsing to basic file indexing

  • File Analysis: Deep insights into structure, imports, classes, methods, and complexity metrics after running build_deep_index

  • 10 Languages with Tree-sitter AST Parsing: Python, JavaScript, TypeScript, Java, Kotlin, C#, Go, Objective-C, Zig, Rust

  • 50+ File Types with Fallback Strategy: C/C++, Ruby, PHP, and all other programming languages

  • Document & Config Files: Markdown, JSON, YAML, XML with appropriate handling

  • Web Frontend: Vue, React, Svelte, HTML, CSS, SCSS

  • Java Web & Build: JSP/Tag files (.jsp,.jspx,.jspf,.tag,.tagx), Grails/GSP (.gsp), Gradle & Groovy builds (.gradle,.groovy),.properties, and Protocol Buffers (.proto)
