i am looking for an options parser that can handle options with - or -- or + or ++. it must support combining single letter options in the same argument (for both - and + including - and + in the same argument), -- or ++ alone to end options (for arguments alone or arguments that look like options), and option to argument tracking (for each argument, which options are closest, before or after it). i want to convert all my old commands written in C. or else i might have build my own options class.
Argparse handles both i believe
https://docs.python.org/3/library/argpar...efix-chars
Im not sure beyond that as i never use + prefix for options.
I would assume something like this
-f/--foo or -b/--bar or +f/++foo or +b/++bar can all be used.
f and
foo are result back to foo key in dictionary.
import argparse
parser = argparse.ArgumentParser(prog='PROG', prefix_chars='-+')
parser.add_argument('+f', '++foo')
parser.add_argument('-f', '--foo')
parser.add_argument('+b', '++bar')
parser.add_argument('-b', '--bar')
args = vars(parser.parse_args())
print(args)Output:
