argparsedirs 0.2.0

A simple extension for argparse to allow readable/writeable dir types

This is a very simple action for argparse that allows you to specify a readable or a writeable directory as an argparse action. I found it on StackOverflow years ago and used it since then, unfortunately I cannot find the original source now.

I guess it would be best to have this added directly into argparse anyway.

Usage

Just import and use as an action:

import argparse
import argparsedirs

argparser = argparse.ArgumentParser()

argparser.add_argument('indir', type=argparsedirs.ReadableDirType)
argparser.add_argument('outdir', type=argparsedirs.WriteableDirType)

args = argparser.parse_args()
