Bash complains of a missing compopt command

[aalmiray]

I've got the following output every time I press after generating the completion script using the default AutoComplete subcommand from PicoCLI 4.6.2:

-bash: compopt: command not found

$ echo $BASH_VERSION
3.2.57(1)-release

$uname -a
Darwin aalmiray2.local 20.6.0 Darwin Kernel Version 20.6.0: Mon Aug 30 06:12:21 PDT 2021; root:xnu-7195.141.6~3/RELEASE_X86_64 x86_64

Apparently compopt is an alias for complete that's added only if $ZSH_VERSION is set, however the functions applied for Bash will still call that alias.

Ok, interesting. Apparently the shell builtin compopt is not available on the outdated bash version 3.2.57 that ships with Mac OS.

I found a nice suggestion here to replace compopt +o default with this:

type compopt &>/dev/null && compopt +o default

I will fix that in the next release of picocli.

Meanwhile, you can ask your users to run the following command (or make it part of the installation):

sed -i 's/compopt +o default/type compopt &>/dev/null && compopt +o default/g' path/to/completion_script

Would that work?

I committed the fix described above.
If you have any feedback that would be great. ;-)
