Jo - Git Codebase Analyzer

A command-line tool for analyzing Git repositories and extracting code structure information. Supports both Python and TypeScript codebases.

Installation

1. Install Python dependencies:

pip install -r requirements.txt

2. Install Node.js dependencies (required for TypeScript analysis):

npm install -g typescript
npm install -g ts-node

Usage

1. Start analyzing a Git repository:

jo start /path/to/repository

2. View the detailed analysis:

jo map /path/to/repository

You can also get the output in JSON format:

jo map /path/to/repository --format json

Clear all cached analyses:

jo drop

The analysis will:

1. Analyze all Python and TypeScript files in the repository
2. Extract information about:
   • Functions and methods (with parameters and return types for TypeScript)
   • Classes (with properties and inheritance for TypeScript)
   • Interfaces (TypeScript)
   • Type aliases (TypeScript)
3. Store relationships between code elements
4. Cache results in a local SQLite database

Features

• Extracts functions, methods, and classes from Python code
• Analyzes TypeScript-specific features:
  • Interfaces and their properties
  • Type aliases and definitions
  • Function parameter types and return types
  • Class properties and inheritance
• Stores results in a local cache for quick access
• Simple command-line interface
• Multiple output formats (text and JSON)

Requirements

• Python 3.6+
• Node.js 14+ and npm (for TypeScript analysis)
• Git
