# AutoReqGen

> ⚡ A smarter alternative to pipreqs — AutoReqGen scans your entire project recursively, accurately generates requirements.txt with exact versions, formats your code using tools like Black or isort, and even auto-generates documentation from your docstrings. One tool to automate and optimize your Python workflow.

## 🚀 Quickstart

### Install the package

```bash
pip install autoreqgen
```

### Scan your project

```bash
autoreqgen scan .
```

### Generate requirements.txt with version numbers

```bash
autoreqgen generate .
```

### Add a package and update requirements.txt

```bash
autoreqgen add requests
```

### Format the code using black

```bash
autoreqgen format black .
```

### Generate documentation

```bash
autoreqgen docs . --output docs.md
```

### Watch your project and update requirements.txt on change

```bash
autoreqgen watch .
```

### Start a new project virtual environment

```bash
autoreqgen start
```

### Freeze your current environment into a clean requirements.txt

```bash
autoreqgen freeze
```

## 📁 Example Structure

```
myproject/
├── main.py
├── utils/
│   └── helper.py
├── requirements.txt
├── DOCUMENTATION.md
```

## 📚 Detailed Usage

### Scanning Projects

Scan a project to identify all Python imports:

```bash
autoreqgen scan /path/to/project
```

### Generating Requirements

Generate a requirements.txt file with all necessary packages:

```bash
# Default (with version numbers)
autoreqgen generate /path/to/project

# Without version numbers
autoreqgen generate /path/to/project --no-versions

# Output as JSON
autoreqgen generate /path/to/project --as-json

# Include all imports (even standard library)
autoreqgen generate /path/to/project --all
```

### Dependency Management

Add packages to your project and requirements.txt:

```bash
# Add single package
autoreqgen add requests

# Add multiple packages
autoreqgen add requests pandas numpy

# Add with specific version
autoreqgen add "requests>=2.25.0"
```

Freeze your environment to create a reproducible requirements.txt:

```bash
autoreqgen freeze
```

### Code Formatting

Format your code using different tools:

```bash
# Format with black
autoreqgen format black /path/to/project

# Format with isort
autoreqgen format isort /path/to/project

# Format with autopep8
autoreqgen format autopep8 /path/to/project

# Chain formatters
autoreqgen format black,isort /path/to/project
```

### Documentation Generation

Generate documentation from your docstrings:

```bash
# Basic usage
autoreqgen docs /path/to/project

# Specify output file
autoreqgen docs /path/to/project --output API.md

# Generate for specific modules
autoreqgen docs /path/to/project --modules main.py,utils
```

### Live Watching

Watch your project for changes and automatically update requirements.txt:

```bash
# Watch project
autoreqgen watch /path/to/project

# Watch with specific interval (in seconds)
autoreqgen watch /path/to/project --interval 5

# Watch and format on change
autoreqgen watch /path/to/project --format black
```

### Project Initialization

Start a new Python project with a virtual environment:

```bash
# Create a new virtual environment in the current directory
autoreqgen start

# Specify Python version
autoreqgen start --python 3.10

# Create with specific packages
autoreqgen start --packages "requests pandas"
```

## 🔧 Configuration

AutoReqGen can be configured using environment variables or `.env` files:

```
AUTOREQGEN_DEFAULT_FORMAT=black
AUTOREQGEN_IGNORE_DIRS=tests,examples
AUTOREQGEN_INCLUDE_DEV=true
AUTOREQGEN_VERBOSE=true
```
# ⚠️ Google Colab Compatibility Disclaimer

**AutoReqGen** is designed to run in standard Python environments (local, virtualenv, Conda, etc.). While many features work fine in Google Colab, there are some important limitations to be aware of:

## ✅ Features that **work in Colab**:
| Feature             | Status  | Description |
|---------------------|---------|-------------|
| `scan`              | ✅       | Scans Python files or projects to detect external imports. |
| `generate`          | ✅       | Generates `requirements.txt` from scanned imports. |
| `add <package>`     | ✅       | Installs a package and appends it to `requirements.txt`. |
| `freeze`            | ✅       | Freezes the current environment (via `pip freeze`) into `requirements.txt`. |
| `docs`              | ✅       | Extracts module, class, and function docstrings and generates markdown docs. |

## 🚫 Features that **do NOT work in Colab**:
| Feature             | Status  | Reason |
|---------------------|---------|--------|
| `start` (virtualenv creation) | ❌       | Google Colab does not allow creating or managing virtual environments. |
| `watch` (live import updates) | ❌       | `watchdog` cannot run in sandboxed Colab environments due to limited file system access and event monitoring. |

## 📌 Colab-Specific Handling
When you run `AutoReqGen` inside Google Colab:
- The `start` command is **disabled** to prevent errors.
- A clear warning will be shown to the user:
  ```
  ⚠️  Virtual environment creation is not supported in Google Colab.
  ```

## 💡 Tip
You can still install `AutoReqGen` in Colab and use it like this:

```bash
!pip install autoreqgen
!autoreqgen scan .
!autoreqgen generate .
!autoreqgen freeze
```

---

For full functionality, we recommend running **AutoReqGen** in a local or server-based Python environment (outside Colab).
