A free layer to create logics for your arguments

logicparser is a python package that allow you to create logic and dependncies between CLI arguments. These instructions will install logicparser to your machine.

• Python3
• PIP3

pip3 install logicparser 

The class used to create a new argument is imported in this way:

from logicparser import Argument

arg = Argument(arg_name='--arg-name')

arg = Argument(arg_name='--arg-name', metavar='ARG_VALUE')

arg = Argument(arg_name='--arg-name', action='store_true')

arg = Argument(arg_name='--arg-name', help='This message will be show when you will define -h arg')

You can define that an argument can be defined only if others arguments are defined previously

arg = Argument(
    arg_name='arg-name',
    require=('--other-arg',))

You can define that an argument cannot be defined if other arguments are defined previously

arg = Argument(
    arg_name='arg-name',
    conflict=('--other-arg',))

You can define that an arguments can be defined only if at least one of others arguments is defined

arg = Argument(
    arg_name='arg-name',
    dependency=('--other-arg1', 'other-arg2',))

When you have defined the list of your arguments you can play args validation parsing them.

from logicparser import Argument, ArgumentHandler

args = ArgumentHandler([
    Argument(arg_name='--arg-name', ...),
    Argument(arg_name='--arg-name2', ...),
    Argument(arg_name='--arg-name3', ...),
    ...
]).args
