CliMaker
Python package which allows to define a CLI argument parser (with subcommands) with a schema.
The only dependency is the argparse library.
Tested (a bit) with Python 3.6+
Please, create an issue if you have a bug-report or find this package needs an improvement. (It definitely needs an improvement.)
Installation
pip install climaker
Example
import sys
from climaker import Parser, Subcommands, Arguments, Arg
# Define commands structure
spec = Subcommands({
'bake': Subcommands({
'cake': Arguments([
Arg('-s', '--size', type_=int, default=10),
Arg('--color', default='pink'),
]),
'cookie': Arguments([
Arg('--kind', default='biscuit'),
]),
}),
'eat': Arguments([
Arg('edible', default='cookie'),
])
})
# Create a parser
parser = Parser(spec)
# Parse arguments
action = parser.parse_arguments(sys.argv[1:])
print(action.command)
# ['bake', 'cake']
print(action.params)
# {'size': 10, 'color': 'pink'}
