Does this still work?

The instructions are confusing or I'm too dumb to figure them out or this doesn't work on Debian bullseye anymore running bash 5.1.4. I installed this with apt get bash-completion

I have an alias for docker called "dk".

I created file in home directory called complate_alias with following:

complete -F _complete_alias dk

In a newly created file called .bash_completion in my home dir, I have . /home/admin/complete_alias. I also put the same in ~/.bashrc.

I logged out and back into the shell. Resource all the files above. Still get:

dk <tab>-bash: completion: function _complete_alias' not found`

Ok, I manually ran the following commands:

complete -F _complete_alias dk
complete -F _docker dk

And things started to work. I'm not entirely sure why, though.

One thing I'm noticing is that completion does not work with the alias until a completion has been run using the full command name at least once. 🤷🏽‍♂️

I don't have anything else in ~/.bash_completion so I just saved the complete_alias file as ~/.bash_completion

Also I have this note in my /etc/bash.bashrc which may or may not be relevant

# Debian doesn't have bash-completion by default so you need to apt install bash-completion and add the below
# also don't forget about https://github.com/cykerway/complete-alias
if [ -f /etc/bash_completion ]; then
    . /etc/bash_completion
fi

for my use-case i do not need complete-alias, however i had this issue also & resolve it by writing

_completion_loader $program_name
complete -F _$program_name $alias_name

the completion function may be something other than _$program_name depending on what it is. also, this works with anything, it is not limited to aliases

complete -F _complete_alias dk

i made the same mistake. you need to COPY the complete_alias file from the repo an APPEND your completion command to it. the example in the read me walks you through it.
