Finally I done it. Installed bash5 in parallel with the one from the system. 

It's a lot better. After some try and retry I added something simple. 

_commandcomp()
{
  local w
  w="$2"
  local CMDS=$( _get_custom_commands )

  COMPREPLY=( $(compgen -W "$CMDS" "$w") )
}
complete -I -F _commandcomp

Now starting to type a command at an emtpy prompt and pressing tab, I have
completion proposals only from my custom commands. That's good. 

When I was trying to achieve that, by accident I entered a colon ":" at an empty
prompt. I expected that it will do nothing but in fact that lists all files in
the current directory. 

$ :<TAB><TAB>
bash-5.0-patches/       bash.SlackBuild~        slack-desc
bash-5.0.tar.lz         bash_manpages.patch.gz  
bash.SlackBuild         doinst.sh.gz

Is this an expected behaviour ? It does not seem to reach the -I part. 
I tried other characters but for the moment just this one is doing that. 

kaycee,
