Major Features & Improvements

• Enhanced Search Capabilities with Elasticsearch-like Query Syntax:

  • Implemented advanced query syntax inspired by Elasticsearch, including:
    • Logical operators (AND, OR, NOT)
    • Required (+) and excluded (-) terms
    • Grouping with parentheses
    • Field-specific searching
    • Wildcards for flexible matching
  • This allows for more precise and powerful code searches.

• Interactive AI Chat Mode:

  • Added a new interactive AI chat mode, accessible via npx -y @buger/probe-chat and npx -y @buger/probe-chat --web
  • Allows users to ask natural language questions about their codebase and receive AI-powered answers.
  • Supports Anthropic Claude, Google and OpenAI models (API key required).
  • Includes session-based search caching to avoid redundant code snippets in conversations.

• Code Extraction Tooling:

  • Introduced a new extract command for CLI, MCP server, and Node.js SDK.
  • Supports extracting code blocks by:
    • Line numbers (e.g., src/main.rs:42)
    • Line ranges (e.g., src/main.rs:10-20)
    • Symbol names (e.g., src/main.rs#function_name)
    • Piping from stdin, allowing integration with other tools like grep and go test
  • Uses tree-sitter to intelligently extract complete code blocks (functions, classes, etc.).
  • Supports multiple output formats including markdown, plain, json, and xml.

• Node.js SDK (@buger/probe NPM Package):

  • Published a new @buger/probe NPM package providing a Node.js SDK.
  • Enables programmatic access to Probe's core functionalities (search, query, extract).
  • Includes pre-built AI tool integrations for Vercel AI SDK and LangChain.
  • Simplifies embedding Probe into Node.js applications and AI tooling.

• MCP Server Enhancements (@buger/probe-mcp NPM Package):

  • Published @buger/probe-mcp NPM package for the MCP server.
  • Improved MCP server with new query_code and extract_code tools.
  • Enhanced error handling and logging.
  • Streamlined binary management using the @buger/probe package.

• Web Interface for Team Collaboration (@buger/probe-web NPM Package Example):

  • Published @buger/probe-web as an example NPM package showcasing the web interface.
  • Provides a browser-based UI for code search and AI-powered code exploration.
  • Features an interactive chat UI, Mermaid diagram support, and configurable search paths.
  • Includes API endpoints for programmatic access.

• Performance and Binary Size Optimizations:

  • Optimized release builds for smaller binary size and improved performance.
  • Implemented link-time optimization (LTO) and stripping symbols.
  • Enhanced search speed with optimized algorithms and caching.

• Codebase Modernization and Refactoring:

  • Refactored the chat module for better modularity and maintainability.
  • Improved code structure and error handling throughout the codebase.
  • Enhanced test suite with new integration and unit tests.

• Developer Experience Improvements:

  • Added new install target to Makefile for easier binary installation.
  • Introduced .roomodes for custom Roo modes and improved AI assistant guidance.
  • Added issue templates and contributing guidelines for community contributions.
  • Enhanced debug logging and error reporting for easier troubleshooting.

• Security Enhancements:

  • Added SECURITY.md file with vulnerability reporting procedures and security policy.
  • Implemented optional basic authentication for the web interface.
  • Improved handling of user inputs and API keys.
