Requirements

• Python 3.8 or above
  • argparse
  • logging

Installation

pip install arbutus

Usage

Once installed, the cli can be defined using a yaml file, using the keywords branches to define new branch names and arguments to define new arguments and it's characteristics. For example:

main:
  branches:
    sum:
      arguments:
        integers:
          type: float
          nargs: +
          help: list of integers to sum
          action:
            name: sum_
            source: sample
    store:
      arguments:
        something:
          type: str
          nargs: +
          help: string or strings to store
          action: store

The yaml above would imply that a module named sample includes the action sum_, and makes use of the store action. These actions can be defined using the @Arbutus.new_action wrapper. For example:

from arbutus import Arbutus

@Arbutus.new_action
def sum_(*args, **kwargs):
    total = 0
    for number in kwargs['values']:
        total += number
    print(total)

Finally, the CLI itself can be constructed by calling the from_yaml method:

import arbutus

if __name__ == '__main__':
    cli = arbutus.Arbutus()
    cli.from_yaml('sample/cli.yaml')
    cli.parse_args()

The CLI can then be called like:

# This would display general help about the CLI functionality
python3 sample/sample.py -h
# This would display general help about the sum test functionality
python3 sample/sample.py sum -h
# This would throw the result of running the sum function with the passed arguments
python3 sample/sample.py sum 12 25 3
