📊 Output Format

Git-Ingest supports two output formats optimized for different use cases. Markdown is now the default output format.

📝 Markdown Format (Default, LLM-Optimized)

The default output is a structured, semantic Markdown format designed for optimal AI/LLM processing:

git-ingest

Features:

• 🎯 LLM-Friendly Structure: Hierarchical organization with proper semantic markup
• 🔍 Language Detection: Automatic syntax highlighting for 60+ programming languages
• 📊 Rich Metadata: File statistics, language distribution, and categorization
• 📑 Table of Contents: Navigation-friendly structure with links
• 🏷️ File Categorization: Organized by Web Frontend, Backend, DevOps, etc.
• 💻 Code Blocks: Proper syntax highlighting for better readability
• 📈 Analytics: Comprehensive project statistics and insights

Example markdown output structure:

# 🚀 Project Analysis Report

## 📊 Project Overview

**Language:** javascript | **Files:** 25 | **Size:** 2.3 MB

## 📈 Statistics

### 📊 File Type Distribution

| Category       | Files | Percentage |
| -------------- | ----- | ---------- |
| Web Frontend   | 15    | 60.0%      |
| Backend/Server | 8     | 32.0%      |

### 📄 `app.js`

**Path:** `src/app.js`
**Size:** 3.2 KB
**Language:** javascript (high confidence)
**Category:** Web Frontend

```javascript
// Your code here with proper syntax highlighting
```

📝 Text Format (Legacy)

The classic plain text format with directory tree and file contents:

git-ingest --format text

Example:

🛠️ Configuration

Git-Ingest respects standard .gitignore files and includes sensible defaults:

Default Exclusions

• Generated output files (git-ingest-*.txt, git-ingest-*.json)
• Version control (.git/)
• Dependencies (node_modules/, vendor/)
• Build directories (dist/, build/, out/)
• Binary files (images, videos, executables)
• IDE files (.vscode/, .idea/)
• OS files (.DS_Store, Thumbs.db)

Custom Configuration

Use include/exclude patterns to customize file selection:

# Only include JavaScript and TypeScript files
git-ingest --include "*.js" "*.ts" "*.jsx" "*.tsx"

# Exclude test files
git-ingest --exclude "*.test.js" "*.spec.js" "__tests__/"

# Complex filtering
git-ingest --include "src/**" --exclude "*.min.js" "*.bundle.js"
