# File Combiner
[![PyPI version](https://badge.fury.io/py/file-combiner.svg)](https://badge.fury.io/py/file-combiner)
[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://opensource.org/licenses/MIT)
[![Python](https://img.shields.io/badge/python-3.8+-blue.svg)](https://www.python.org/downloads/)
A high-performance file combiner that merges entire directories into single files and restores them back to their original structure. Features **multi-format output** (TXT, XML, JSON, Markdown, YAML) with intelligent auto-detection. Optimized for AI agents (Claude, ChatGPT, Copilot) and perfect for large codebases.
## ✨ Features
- 🎨 **Multi-Format Output**: TXT, XML, JSON, Markdown, YAML with auto-detection
- 🚀 **High Performance**: Parallel processing with async I/O
- 🔄 **Bidirectional**: Combine ↔ Split operations with perfect fidelity
- 🗜️ **Smart Compression**: Optional gzip compression
- 🤖 **AI-Optimized**: Perfect format for AI agents with syntax highlighting
- 📁 **Deep Recursion**: Handles nested directories
- 🔧 **Universal Support**: Text, binary, and Unicode files
- ⚡ **Advanced Filtering**: Powerful include/exclude patterns
- 🌐 **GitHub Integration**: Direct repository cloning and combining
- 📊 **Progress Tracking**: Beautiful progress bars with rich terminal output
- 🎯 **Cross-Platform**: Linux, macOS, Windows
- 🛡️ **Robust**: Comprehensive error handling and validation
## 🚀 Quick Start
### Installation
```bash
# Basic installation
pip install file-combiner
# With all optional dependencies
pip install file-combiner[full]
# Development installation (using PDM)
git clone https://github.com/davidlu1001/file-combiner.git
cd file-combiner
pdm install -G dev
```
### Basic Usage
```bash
# Combine current directory into a single file (excludes Python cache folders)
file-combiner combine . my-project.txt \
--exclude "__pycache__/**" --exclude "__pypackages__/**"
# Multi-format output with auto-detection
file-combiner combine . project.json # → JSON format (auto-detected)
file-combiner combine . project.xml # → XML format (auto-detected)
file-combiner combine . project.md # → Markdown format (auto-detected)
file-combiner combine . project.yaml # → YAML format (auto-detected)
# Manual format override
file-combiner combine . report.txt --format markdown # → Markdown in .txt file
# Combine a GitHub repository directly
file-combiner combine https://github.com/davidlu1001/file-combiner repo-archive.txt \
--exclude "__pycache__/**" --exclude ".git/**"
# Combine with compression (works with all formats)
file-combiner combine /path/to/repo combined.json.gz --compress \
--exclude "__pycache__/**" --exclude "*.pyc"
# Split archive back to original structure
file-combiner split combined.txt.gz ./restored-project
# Dry run to preview what would be combined
file-combiner combine . output.txt --dry-run --verbose \
--exclude "__pycache__/**" --exclude "__pypackages__/**"
```
## 📖 Advanced Examples
### GitHub Repository Support
```bash
# Combine any public GitHub repository directly
file-combiner combine https://github.com/user/repo combined-repo.txt
# With smart exclusions for clean output
file-combiner combine https://github.com/davidlu1001/file-combiner repo.txt \
--exclude "__pycache__/**" --exclude ".git/**" \
--exclude "*.pyc" --exclude ".pytest_cache/**" \
--exclude "__pypackages__/**" --exclude ".pdm-build/**"
# Compress large repositories
file-combiner combine https://github.com/user/large-repo repo.txt.gz --compress
```
**Requirements for GitHub support:**
- Git must be installed and available in PATH
- Repository must be publicly accessible (or you must have access)
- Temporary directory space for cloning
### AI-Optimized Combining
```bash
# Perfect for sharing with AI agents (excludes common cache/build folders)
file-combiner combine . for-ai.txt \
--exclude "node_modules/**" --exclude ".git/**" \
--exclude "__pycache__/**" --exclude "__pypackages__/**" \
--exclude "*.pyc" --exclude ".pytest_cache/**" \
--max-size 5M
```
### Language-Specific Filtering
```bash
# Only include Python and JavaScript files
file-combiner combine src/ review.txt.gz \
--include "*.py" --include "*.js" --compress
```
### Automated Backups
```bash
# Create timestamped backups
file-combiner combine ~/project backup-$(date +%Y%m%d).txt.gz \
--compress --verbose --exclude "*.log"
```
## 🎨 Multi-Format Output
File-combiner supports 5 output formats, each optimized for different use cases:
### 📄 **TXT Format** (Default)
Traditional plain text format with enhanced headers and metadata.
```bash
file-combiner combine . output.txt
# Auto-detected from .txt extension
```
### 🏷️ **XML Format**
Structured XML with metadata attributes, perfect for enterprise workflows.
```bash
file-combiner combine . output.xml
# Auto-detected from .xml extension
```
### 📋 **JSON Format**
Structured JSON ideal for APIs and programmatic processing.
```bash
file-combiner combine . output.json
# Auto-detected from .json extension
```
### 📝 **Markdown Format**
Beautiful formatted output with syntax highlighting and table of contents.
```bash
file-combiner combine . output.md
# Auto-detected from .md/.markdown extension
```
### ⚙️ **YAML Format**
Human-readable configuration-style format.
```bash
file-combiner combine . output.yaml
# Auto-detected from .yaml/.yml extension
```
### 🎯 **Format Selection**
**Auto-Detection** (Recommended):
```bash
file-combiner combine . project.json # → JSON format
file-combiner combine . project.xml # → XML format
file-combiner combine . project.md # → Markdown format
```
**Manual Override**:
```bash
file-combiner combine . data.txt --format json # JSON in .txt file
file-combiner combine . report.xml --format markdown # Markdown in .xml file
```
**With Compression** (All formats supported):
```bash
file-combiner combine . archive.json.gz --compress
file-combiner combine . docs.md.gz --format markdown --compress
```
### 🎨 **Format Comparison**
| Format | Best For | Features | Size |
| ------------ | ------------------------------------- | -------------------------- | ------ |
| **TXT** | Traditional workflows, simple sharing | Enhanced headers, metadata | Medium |
| **XML** | Enterprise, structured data | Attributes, validation | Large |
| **JSON** | APIs, data processing | Structured, parseable | Medium |
| **Markdown** | Documentation, AI training | Syntax highlighting, TOC | Medium |
| **YAML** | Configuration, human-readable | Clean format, hierarchical | Small |
### 🤖 **AI-Optimized Formats**
For AI agents and code analysis:
```bash
# Markdown with syntax highlighting (recommended for AI)
file-combiner combine . ai-training.md --exclude "__pycache__/**"
# JSON for programmatic processing
file-combiner combine . data-analysis.json --exclude "node_modules/**"
# YAML for configuration-style output
file-combiner combine . config-review.yaml --exclude ".git/**"
```
## ⚙️ Configuration
Create `~/.config/file-combiner/config`:
```python
max_file_size = "50M"
max_workers = 8
verbose = false
exclude_patterns = [
"node_modules/**/*",
"__pycache__/**/*",
"__pypackages__/**/*",
"*.pyc",
".pytest_cache/**/*",
".git/**/*",
".venv/**/*",
"venv/**/*"
]
include_patterns = [
"*.py",
"*.js",
"*.md"
]
```
## 🚀 Performance
- **Small projects** (<100 files): ~0.1s
- **Medium projects** (1000 files): ~2-5s
- **Large repositories** (10k+ files): ~30-60s
- **Parallel processing**: 4-8x speedup on multi-core systems
## 🧪 Development
```bash
# Install PDM (if not already installed)
pip install pdm
# Install project and development dependencies
pdm install -G dev
# Run tests
pdm run pytest
# Format code
pdm run black file_combiner.py
# Lint code
pdm run flake8 file_combiner.py
# Type checking
pdm run mypy file_combiner.py
# Run tests with coverage
pdm run pytest --cov=file_combiner
# Demo multi-format output
make multi-format-demo
```
