autoargparse

Make CMD arg-parser easy and simple.

dependency

• python can import argparse

How to use

1. pip install autoargparse

2. import autoargparse

3. Initialize :
   cmd = autoargparse.cmd()

4. Use functon decorator :
   
   @cmd.args(short_name, long_name, nargs, help, action, type)
   set function argument as args type

   @cmd.kwargs(arg_name=short_name, nargs, help, action, type)
   set function argument as kwargs type

   @cmd.mark(run_order=None)
   set function run order(integer, bigger first run)

5. Run: cmd.run()

example

#!coding:utf-8

import autoargparse

cmd = autoargparse.cmd('simple calculator for example.')

@cmd.mark(1)
@cmd.kwargs(ne='--negative', action='store_true')
@cmd.kwargs(ma='--max', action='store_true')
@cmd.args('-s', '--sum', '*', type=int)
def add(*args, ma, ne):
    if args or ma or ne:
        d = 0
        if ma:
            d = max(args)
        else:
            d = sum(args)
        if ne:
            d = -d
        print(d)

@cmd.mark(2)
@cmd.args('-v', action='count')
@cmd.args('-m', '--mul', 2, help='MUL!!!', type=int)
def mul(a,b,v=None):
    if not v:
        print(a*b)
    elif v==1:
        print('a * b =', a*b)
    elif v==2:
        print('func =', mul.__name__, 'args =', a, b, v)
        print('a * b =', a*b)

@cmd.mark(3)
@cmd.args('g', type=int, help='print great')
def great(a):
    if a==1:
        print('!!!')
    else:
        print('Great !!!')



if __name__ == "__main__":
    cmd.run()

OUTPUT

python .\example.py -h

usage: test.py [-h] [-s [SUM [SUM ...]]] [--max] [--negative] [-m MUL MUL]
               [-v]
               g

simple calculator for test.

positional arguments:
  g                     print great

optional arguments:
  -h, --help            show this help message and exit
  -s [SUM [SUM ...]], --sum [SUM [SUM ...]]
  --max
  --negative
  -m MUL MUL, --mul MUL MUL
                        MUL!!!
  -v

python .\example.py 1

!!!

python .\example.py 2

Great !!!

python .\example.py 1 -m 2 3

!!!
6

python .\example.py 1 -m 2 3 -v

!!!
a * b = 6

python .\example.py 1 -m 2 3 -vv

!!!
func = mul args = 2 3 2
a * b = 6

python .\example.py 1 -s 1 2 3 4

!!!
10

python .\example.py 1 -s 1 2 3 4 --max

!!!
4

python .\example.py 1 -s 1 2 3 4 --negative

!!!
-10

TODO

• add GUI
• more easy to use
