snaparg 0.2.0

A typo-tolerant CLI parser wrapper for argparse

snaparg – Smarter argparse for easy living

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.

You can even replace it in any script just by editing your import statement!
