What is cli_args_system ?

In an general way its a library to manipulate argv args its content and its flags

Basic Usage

the most basic application:

from cli_args_system import Args

args = Args()
print(args)

running:

$ python3  test.py  -a "value of a" -b "value of b"

results:

{
    "default": [],
    "a": [
        "value of a "
    ],
    "b": [
        "value of b"
    ]
}

Args:

retrieving the args:

from cli_args_system import Args

args = Args()

list_of_args = args.args()
print(list_of_args)

accessing args index:

from cli_args_system import Args

args = Args()

try:
    print(f'second arg is {args[1]}')
except IndexError:
    print('there less than 2 args')

making iterations:

from cli_args_system import Args

args = Args()

for a in args:
    print(a)

Flags:

retrieving all flags dict:

from cli_args_system import Args

args = Args()

flags = args.flags_dict()
print(flags)

running:

 python3 test.py 0 0x   -a 10 1a -b 20 1b 
 -> {'default': [0, '0x'], 'a': ['10', '1a'], 'b': [20, '1b']}

getting FlagsContent Object:

from cli_args_system import Args

args = Args()
out = args.flags_content('o','out')
print(out)

running:

python3 test.py -o a.txt
 -> 
exist:  True
filled: True
args:   ['a.txt']

retrieving flags and making iterations:

from cli_args_system import Args

args = Args()
out = args.flags_content('o','out')

full_list = out.flags()

try:
    first_element = out[0]
    print(f'first element is: {first_element}')
except IndexError:pass 

#making iterations
for f in out:
    print(f)

print(f'full list is: {full_list}')

running:

python3 test.py -o a.txt b.txt
 -> 
first element is: a.txt
a.txt
b.txt
full list is: ['a.txt', 'b.txt']

checking Flags Status:

from cli_args_system import Args

args = Args()
out = args.flags_content('o','out')

if out.exist():
    print('out flag exist')

if out.exist_and_empty():
    print('out flag exist but its empty')

if out.filled():
    print('out flag its filled')

if 'a.txt' in out:
    print('a.txt in out flag')

running:

python3 test.py -o a.txt
->
out flag exist
out flag its filled
a.txt in out flag
