gen-reqs 0.1.0

A tool to automatically detect Python project dependencies and generate requirements.txt

Python Dependencies Generator

A simple tool to automatically detect Python project dependencies and generate requirements.txt. It analyzes your Python files recursively, detects imports, and handles common package name mappings (like 'yaml' → 'PyYAML').

Installation

pip install gen-reqs

Usage

From the command line:

gen_reqs

This will:

1. Scan all Python files in the current directory and subdirectories
2. Detect third-party imports
3. Map import names to correct package names (e.g., 'yaml' → 'PyYAML')
4. Generate a requirements.txt file

Features

• Recursive scanning of Python files
• Automatic detection of third-party imports
• Mapping of common import names to correct package names
• Filtering out standard library modules
• Detection of local modules (to exclude them)

Common Package Mappings

The tool handles many common package name mappings, including:

• yaml → PyYAML
• dotenv → python-dotenv
• PIL → Pillow
• sklearn → scikit-learn
• And many more...

As a Python Module

You can also use it in your Python code:

from python_deps_generator import generate_requirements

# Generate requirements.txt in current directory
generate_requirements()

# Or specify a directory
generate_requirements("/path/to/project")
