A typo-tolerant CLI parser wrapper for argparse
Project description
snaparg
snaparg is a lightweight Python library that wraps around the built-in argparse module, making command-line interfaces more user-friendly by detecting typos in argument names and suggesting the closest valid alternatives.
Perfect for scripts and tools that aim to be a little more forgiving to users without sacrificing the power and flexibility of argparse.
✨ Features
- Drop-in replacement for
argparse.ArgumentParser - Detects mistyped CLI flags and suggests corrections
- Compatible with existing
argparse-based code - Zero dependencies — works out of the box
🔧 Example
$ python demo.py --iput file.txt
Error: Unknown or invalid argument(s).
Did you mean: '--iput' -> '--input'?
Full message:
usage: demo.py [-h] [--input INPUT] [--output OUTPUT] [--force]
📦 Installation
