bash: Multiple subparser commands don't complete correctly

[NiklasReisser]

Hi,

since #81 , shtab always only completes the first subparser command. The minimal example below immediately completes "bla".

The Reason seems to be that

shtab/shtab/__init__.py

Line 357 in 60a8525

current_action_choices="${!current_action_choices_var}"

only expands the first value of the _choices array. Unfortunately, I have not found a solution without breaking #81 again.
Happy to try any idea though.

#!/usr/bin/env python3

import argparse
import shtab

parser = argparse.ArgumentParser()
shtab.add_argument_to(parser, ["--print-completion"])

subparsers = parser.add_subparsers()

subparser1 = subparsers.add_parser('bla', help="hi")
subparser2 = subparsers.add_parser('blub', help="hi")

args = parser.parse_args()

Cheers
Niklas

DVC has issues with that too:

I have the Issue with DVC tab completion.

Current workaround as suggested in Discord is:

1. Downgrade shtab (pip install shtab==1.5.4)
2. dvc completion -s bash | sudo tee /etc/bash_completion.d/dvc
3. reload terminal/ open a new one, try again

@alkatar21 could you give the new version a try?

Yes, the subcommands autocomplete correct again, thanks👍
