dtargs 1.0.0

Introduction

dtargs is a small module that makes accepting date/time arguments with Argparse easier.

Examples

A date argument

import argparse
import dtargs

parser = argparse.ArgumentParser()
parser.add_argument('start', type=dtargs.DateType()) # defaults to %Y-%m-%d
parser.add_argument('end', type=dtargs.DateType('%d/%m/%Y'))

A date/time argument

import argparse
import dtargs

parser = argparse.ArgumentParser()
parser.add_argument('start', type=dtargs.DateTimeType()) # defaults to %Y-%m-%dT%H:%M:%SZ
parser.add_argument('end', type=dtargs.DateTimeType('%H:%M:%S_%Y-%m-%d', tz=None)

Timezones

The DateTimeType accepts a tz parameter, which is handled thusly

import dtargs

dtargs.DateTimeType()('2015-01-02T12:34:56Z')
>>> datetime.datetime(2015, 1, 2, 12, 34, 56, tzinfo=<UTC>)

dtargs.DateTimeType(tz=None)('2015-01-02T12:34:56Z')
>> datetime.datetime(2015, 1, 2, 12, 34, 56, tzinfo=None)

dtargs.DateTimeType('%Y-%m-%dT%H:%M:%S%z', tz=None)('2015-01-02T12:34:56+0100')
>> datetime.datetime(2015, 1, 2, 12, 34, 56, tzinfo=datetime.timezone(datetime.timedelta(0, 3600))

dtargs.DateTimeType('%Y-%m-%dT%H:%M:%S%z', tz=pytz.utc)('2015-01-02T12:34:56+0500')
>> datetime.datetime(2015, 1, 2, 7, 34, 56, tzinfo=<UTC>)
