Accepted values not working

[croissong]

Hi,
the acceptable values feature does not work for me.
I am using GNU bash, version 4.4.23(1)-release (x86_64-unknown-linux-gnu).
The __argsparse_is_array_declared check never returns true.
Replacing the line with a simple is-set check [[ ! -z ${!array_name+x} ]] (stackoverflow) however, works for me.
I could create an PR, if you want :)

Thanks

Hi, thank you for the report, I can reproduce that on my bash 4.4.23 setup on fedora 28. There's a change in the declare -p output for arrays in bash 4.4.

See latest commit on master. That should do the trick.

Thanks so much, awesome work!
