GitHub Repository Structure Analyzer

A Python utility for cloning GitHub repositories and generating a JSON-friendly representation of their directory structure. This tool provides a clean way to analyze repository layouts while respecting .gitignore rules and offering customizable exclude patterns for different project types.

Features

• Clone GitHub repositories with progress visualization
• Generate nested JSON representation of repository structure
• Support for private repositories via GitHub tokens
• Respect .gitignore patterns
• Configurable depth limit for directory traversal
• Pre-defined exclude patterns for common project types (Python, Node.js, Java)
• Progress bar visualization during cloning using alive-progress
• Handles symlinks and special files appropriately

Installation

Prerequisites

Make sure you have Python 3.6+ installed. Then install the required dependencies:

pip install -r requirements.txt

Usage

Basic Usage

from repo_structure import get_repo_structure

# Simple example with default settings
structure = get_repo_structure(
    github_url="https://github.com/username/repo.git",
    clone_path="local_repo_folder"
)

Advanced Usage

from repo_structure import get_repo_structure, PROJECT_EXCLUDES
import json

# Using project-specific excludes and depth limit
structure = get_repo_structure(
    github_url="https://github.com/username/repo.git",
    clone_path="local_repo_folder",
    token="your_github_token",  # For private repos
    max_depth=2,  # Limit directory traversal depth
    exclude_patterns=PROJECT_EXCLUDES["python"]  # Use Python-specific excludes
)

# Print the structure as formatted JSON
print(json.dumps(structure, indent=2))

Private Repositories

For private repositories, you'll need to provide a GitHub personal access token:

structure = get_repo_structure(
    github_url="https://github.com/oguzhancetinkaya/private-repo.git",
    clone_path="private_repo_folder",
    token="your_github_personal_access_token"
)

Exclude Patterns

The tool comes with predefined exclude patterns for different project types:

• DEFAULT_EXCLUDES: Basic patterns like .git, node_modules, venv
• PYTHON_EXCLUDES: Python-specific patterns
• NODE_EXCLUDES: Node.js-specific patterns
• JAVA_EXCLUDES: Java-specific patterns

You can also provide your own custom exclude patterns:

custom_excludes = [
    "*.log",
    "temp",
    "custom_folder"
]

structure = get_repo_structure(
    github_url="https://github.com/username/repo.git",
    clone_path="local_repo_folder",
    exclude_patterns=custom_excludes
)

Output Format

The tool generates a nested dictionary structure that represents the repository layout:

{
  "name": "repo_name",
  "type": "directory",
  "children": [
    {
      "name": "src",
      "type": "directory",
      "children": [
        {
          "name": "main.py",
          "type": "file"
        }
      ]
    }
  ]
}

Components

repo_structure.py
