Babar :elephant:

Babar is an intelligent codebase analyzer designed to bridge the gap between your existing codebase and modern AI-powered development workflows. By recursively analyzing your project's directory structure and creating smart summaries, Babar helps both developers and AI tools better understand and work with your codebase.

Why Babar?

• 🤖 AI-First Documentation: Creates documentation that's optimized for both humans and AI assistants
• 📦 Codebase Understanding: Helps new developers and AI tools quickly understand your project structure
• 🔄 Living Documentation: Automatically updates as your codebase evolves
• 🎯 Contextual Analysis: Provides deep insights about components, patterns, and technical debt
• 🚀 Fast & Efficient: Processes directories in parallel and caches results

Getting Started

Installation

npm install -g babar-ai

Environment Variables

OPENAI_API_KEY=your-api-key-here
DEBUG=false  # Set to true to see OpenAI requests and responses

Configuration

Babar can be customized using a .babar.json file in your project root. This allows you to define:

• Custom analysis sections
• Prompt templates
• OpenAI settings
• File patterns

Configuration Options

| Option | Description | Default | | --------------------- | ------------------------------- | ------------------------------ | | sections | Define custom analysis sections | See default config | | promptTemplate | Template for the AI prompt | See default config | | model | OpenAI model to use | "gpt-4" | | temperature | AI response creativity (0-1) | 0.1 | | maxTokensPerRequest | Max tokens per API call | 4000 | | includeFiles | File patterns to analyze | ["**/*.js", "**/*.jsx", ...] | | excludePatterns | File patterns to ignore | ["**/node_modules/**", ...] |

Each section in the sections object requires:

• type: Either "string" or "array"
• description: What the section should contain
• required: Whether the section is required

The promptTemplate supports these variables:

• {fileCount}: Number of files being analyzed
• {childCount}: Number of subdirectories
• {sections}: Auto-generated section prompts
• {includeSubdirs}: Subdirectory analysis prompt

Default Configuration

By default, Babar analyzes your codebase with these sections:

{
  "sections": {
    "components": {
      "type": "array",
      "description": "Key components and modules",
      "required": true
    },
    "architecture": {
      "type": "string",
      "description": "Component interactions and patterns",
      "required": true
    },
    "conventions": {
      "type": "string",
      "description": "Coding standards and practices",
      "required": true
    },
    "refactoringOpportunities": {
      "type": "array",
      "description": "Potential improvements",
      "required": true
    },
    "technicalDebt": {
      "type": "string",
      "description": "Areas needing attention",
      "required": true
    }
  },
  "promptTemplate": "You are a technical documentation expert analyzing {fileCount} files and {childCount} subdirectories.\n\nCreate a comprehensive analysis following this structure:\n\n{sections}\n\n{includeSubdirs}\n\nFocus on clarity and maintainability. Explain complex concepts clearly.",
  "model": "gpt-4",
  "temperature": 0.1,
  "maxTokensPerRequest": 4000,
  "includeFiles": ["**/*.js", "**/*.py", "**/*.rb"],
  "excludePatterns": ["**/node_modules/**", "**/dist/**"]
}

Configuration Priority

1. Environment variables take highest precedence
2. Project-specific .babar.json
3. Default configuration

Usage

# Analyze current directory
babar -d .

# Analyze specific directory
babar -d /path/to/project

# Show help
babar --help

How It Works

1. Babar recursively scans your project directory
2. For each directory, it:
   • Lists all files and subdirectories
   • Analyzes the contents using GPT-4
   • Generates a .babar.md file with the analysis
3. The analysis includes:
   • Key components and their purposes
   • Architecture patterns
   • Coding conventions
   • Potential improvements
   • Technical debt notes

Using with AI Assistants

To help AI assistants understand your codebase, add this to your assistant's configuration:

{
  "contextRules": {
    "includeFiles": ["**/.babar.md"],
    "maxFilesToSearch": 500,
    "maxCharsPerFile": 100000
  },
  "fileSearch": {
    "include": ["**/.babar.md"],
    "exclude": [],
    "maxResults": 10
  }
}

This configuration:

1. Includes .babar.md files in the context provided to AI assistants
2. Prioritizes .babar.md files during codebase searches
3. Ensures the AI has access to Babar's hierarchical documentation when answering questions about your codebase

For the best results:

• Run Babar before starting new development sessions to ensure up-to-date context
• Consider adding .babar.md files to your version control to share context with your team
• Exclude .babar.md files from your .gitignore if you want to preserve the analysis across clones
