Public bug reported:
I'm on Noble. I don't believe there's anything special about my
environment with respect to Bash completions. I had pipx installed to
prevent conflicts with the system python, which brings in the
python3-argcomplete package. I've temporarily removed the former but
kept the latter, in order to investigate my problem.
When argcomplete is installed, completions in ~/.local/share/bash-
completion/completions/ do not load or run. Their underscore-prefixed
functions do not appear in the environment. To test, I created a file
there for the non-existent command "zz", with these contents:
_zz () {
COMPREPLY=($(compgen -W 'foo bar baz qux' -- "$2"))
} && complete -F _zz zz
At a fresh Bash prompt, I type "zz " then hit Tab. It will only complete
filenames from the current dir, not from the specified argument set.
Under "bash -x", the trace after doing so begins with this:
+ [[ -n '' ]]
+ local _BASH_REMATCH=
+ local executable=
+ req_argv=()
+ local req_argv
+ [[ -z '' ]]
+ executable=zz
+ req_argv=("" "${COMP_WORDS[@]:1}")
+ __python_argcomplete_expand_tilde_by_ref executable
...
If I uninstall the argcomplete package and do the same, fresh prompt
each time, my completions work again. I can reliably toggle this
behaviour by reinstalling & uninstalling it. The successful trace begins
with this:
+ local cmd=zz
+ __load_completion zz
+ dirs=('/home/l/.local/share/bash-completion/completions')
+ local -a dirs
...
