def give(name, item_name, item_amount):
    print(f"You gave {item_amount} {item_name}s to {name}")


# surround argument that contains whitespaces with quotes
# set `convert_args` to `True` to automatically convert numbers argument

# this will raise an exception,
# if the number of arguments provided is less than the number of positional callback parameters.
cmd = cmdtools.Cmd('/give Josh "Golden Apple" 10', convert_args=True)

# check for command instance arguments data type.
# format indicates ['str','str','int'].
# integer or float can also match string format, and character 'c' if the argument only has 1 digit.

# `max_args` set to 3, check the first 3 arguments, the rest will get ignored, 
# otherwise if it set to default,
# it will raise an exception if the number of arguments is not equal to the number of formats
if cmd.match_args('ssi', max_args=3):
    cmd.process_cmd(give)
else:

  • callback options value doesn't get cleared after command executed

    callback options value doesn't get cleared after command executed

    Example code:

    import asyncio
import cmdtools

@cmdtools.callback.add_option("msg", default="")
def test(ctx):
    print(f"{ctx.options.msg!r}")

async def main():
    first_cmd = cmdtools.Cmd("/test hi")
    second_cmd = cmdtools.Cmd("/test")
    
    await cmdtools.execute(first_cmd, test)
    await cmdtools.execute(second_cmd, test)

asyncio.run(main())

    Output:

    'hi'
'hi'

    Expected output:

    'hi'
''

    Possible solution

    Make a copy of the Options instance so the original instance won't get changed.
