bash completion generates "nosort" error on macOS with Bash v3

[jordan-brough]

Describe the bug

I started getting this error (warning?) when opening a new Terminal window on macOS:

-bash: complete: nosort: invalid option name

I'm running Bash v3:

$ bash --version
GNU bash, version 3.2.57(1)-release (arm64-apple-darwin22)
Copyright (C) 2007 Free Software Foundation, Inc.

The error is happening during /opt/homebrew/etc/bash_completion.d/rtx on my system, which is this: https://github.com/jdx/rtx/blob/f333ac5f8e8de399fcb3ce40576baeef0271081b/completions/rtx.bash#L3482

If I remove the -o nosort from that line then the error stops.

This looks related? https://lists.zx2c4.com/pipermail/wireguard/2018-October/003418.html

this is generated (currently, I have some plans to change this) by clap_complete. I'm not sure if bash 3.x is a supported target or not, but if it is, this would need to be addressed upstream

I have the same problem with bash 5.2.15 on macOS for rtx installed via brew

bash --version

Every time I run brew upgrade, I have to update the completion script to remove -o nosort

@skittishdev are you certain that the bash you're running isn't v3? try echo $BASH_VERSION. nosort was added in bash v4 it looks like

[skittishdev]

Oops, you're right @jdx . Sorry!

echo $BASH_VERSION
3.2.57(1)-release

Just ran across this today with default MacOS bash, and noticed that clap_complate merged a fix a few months ago, released in v4.4.6
