Description

Add logic in argpars object with argparsGraph.
This package helps you to avoid the if/else forestswhen using argparse

Install

Install package:

pip install argparse-graph

Uninstall package:

pip uninstall argparse-graph

manually :

Install the package:

make install

Uninstall the package:

make uninstall

Use it

The parameter defined with argparse must be named (dest="argsName")if not, it will
be impossible to find some link between the variable name and the name in the yaml file.

example of argparse object:

python script

from argparseGraph.argparseGraph import argparseGraph as agg

def parsarg():
    parser = argparse.ArgumentParser(description="random options for differents cenarios")
    parser.add_argument("-q", dest="argv1", help="test", type=int)
    parser.add_argument("-w", dest="argv2", help="test", type=int, action='append')
    parser.add_argument("-e", dest="argv3", help="test", type=str, default="test3")
    parser.add_argument("-t", dest="argv4", help="test", type=str, default=False)
    parser.add_argument("-a", dest="argv5", help="test", type=str)
    parser.add_argument("-s", dest="argv6", help="test", type=bool)
    parser.add_argument("-d", dest="argv7", help="test", type=str, action='append')
    args = parser.parse_args()

    return args

res = parsarg()
agg = agg("scenarios.yml", res_args, verbose=False)

scenario.yml

# if all parameters are not None
# cmd: ./main.py -q 1 -w 1 -w 2 -e t -t o -a o -s t -d "Hello"  -d "World"
scenario_1:
  options: "all"
# if argv3, argv4 are not None and other are None
# format list [v1, v2]
# cmd: ./main.py -e toto -t ok
scenario_2:
  options: [argv3, argv4]
# if argv3, argv4, argv5, argv6, argv7 are not None and other are None
# format list     
#    - argv3
#    - argv4
#    - argv5
#    - argv6
#    - argv7
# cmd: ./main.py -e toto -t ok -a ok -s True -d "Hello"  -d "World"
scenario_3:
  options:
    - argv3
    - argv4
    - argv5
    - argv6
    - argv7
# if argv3, argv4, argv6, argv7 are not None and other are None
# format str argv3, argv4, argv6, argv7
# cmd: ./main.py -s False -t True -d "Test"
scenario_4:
  options: argv3, argv4, argv6, argv7

With the argparseGraph object you can get 3 differents results formats, with those methods:

# Return the name of the strategie in the yaml file.
agg.get_one()
# example:
# 'scenario_test'

# Return a dict
agg.get_dict()
# { 'scenario': 'scenario_test', 'options': ['argv3', 'argv4', 'argv5', 'argv6', 'argv7'], 'status': None}

agg.get_all()
# {
#  'scenario_1': {'options': 'all', 'name': 'scenario_1', 'status': 'Fail'},
#  'scenario_2': {'options': ['argv3', 'argv4'], 'name': 'scenario_2', 'status': 'Fail'},
#  'scenario_3': {'options': ['argv3', 'argv4'], 'name': 'scenario_3', 'status': 'Fail'},
#  'scenario_4': {'options': ['argv3', 'argv4', 'argv6', 'argv7'], 'name': 'scenario_4', 'status': 'Fail'},
#  'scenario_test': {'options': ['argv3', 'argv4', 'argv5', 'argv6', 'argv7'], 'name': 'scenario_test', 'status': None},
#  'scenario_5': {'options': '', 'name': 'scenario_5', 'status': 'Fail'}
# }

Tests

Two types of tests are available, the first one is running on the sources in the project directory, the second one is running on the package install on your system.

run test on the package not installed:

make test

run test on the package installed:

make test_install
