Q: in completions/open and completions/launchctl, why the $filenames in the final complete command:
complete $filenames -F _open open
complete -F _launchctl $filenames launchctl

These crash with "set -u" or "set -o nounset" in the invoking bash shell.

To be completely honest, bash completion syntax is black magic to me. This is simply an aggregation of a bunch of independent completions that I've gathered over time. I've tried adding my own and some minor hacking, but it's rather difficult to find best practices (or, really, any practices) online. I don't use those options in my shell so I haven't run into that issue. You're welcome to fork or suggest fixes, though. :)

Ok, the fix is to change

complete $filenames -F _open open
complete -F _launchctl $filenames launchctl

to

complete -o filenames -F _open open
complete -F _launchctl -o filenames launchctl

Thanks

Ah, cool. That makes sense. Thanks!

One more: only look at COMP_WORDS[2] if it exists:
