SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Search inefficiencies in large codebases by enabling targeted navigation, pattern discovery, and context-aware tracing of functions and dependencies.

Core Features & Use Cases

  • Semantic search across codebases to find conceptual matches for features or bugs
  • Grep-style pattern matching to locate exact strings, functions, or identifiers
  • AST-based navigation to understand code structure and dependencies
  • Use cases include tracing function calls, locating legacy code, and analyzing code changes over time

Quick Start

Provide a concise query describing the target (e.g., a function name or pattern) and request a codebase search to locate relevant definitions and usages.

FAQPage Schema
How do I search for function definitions and trace dependencies across a large multi-language codebase?

To search a large multi-language codebase, use semantic search, grep-style pattern matching, and AST-based navigation to locate definitions and trace dependencies. This approach delivers precise results by understanding code structure within Git-tracked repositories.

Can I use semantic search to find conceptual matches for features or bugs in legacy code?

Yes, semantic search finds conceptual matches for features or bugs in legacy code. It identifies code patterns and traces functions across large repositories, enabling targeted navigation and context-aware discovery without requiring exact string matches.

What is the best way to navigate code structure and dependencies using AST analysis?

The best way to navigate code structure is using AST-based navigation, which parses abstract syntax trees to map dependencies and locate definitions. It operates within Git-tracked codebases to deliver precise structural analysis across multi-language projects.

Does codebase search work with Git-tracked repositories to analyze code changes over time?

Codebase search works directly with Git-tracked repositories to analyze code changes over time. It combines grep-style pattern matching and AST-based navigation to locate legacy code and trace function calls within version-controlled projects.

How do I locate exact strings and identifiers using grep-style pattern matching in a large repository?

To locate exact strings and identifiers in a large repository, use grep-style pattern matching. It targets specific function names or identifiers to deliver precise results, operating within Git-tracked codebases for accurate code navigation.

When should I not use semantic search for code navigation in multi-language projects?

Semantic search is not ideal for locating exact string identifiers or simple patterns in multi-language projects. Use grep-style pattern matching for precise string searches, as semantic search focuses on conceptual matches rather than exact identifier retrieval.
