Tab completition fail on function with an alias

[Anselmo95]

Hello,
I here are some details on my system and i did not do touch config apart what specified in the README for the installation.

> fzf --version 
0.58.0 (65db735)

    let fzf take up more space if its available

 > bash --version
GNU bash, version 4.4.20(1)-release

I have the habit of using function within alias, for example:

alias untargzpdf='_untargzpdf(){
                            tar -xvzf $1 --wildcards '*.pdf';
                            unset -f _untargz;
                        }; _untargzpdf'

The autocompletion works for the alias itself but if I try to tab one more time to select a file it does not work and it gives me this error:

~/Programs/fzf-tab-completion/bash/fzf-bash-completion.sh: eval: line 447: syntax error near unexpected token `('
~/Programs/fzf-tab-completion/bash/fzf-bash-completion.sh: eval: line 447: `compspec=( complete -F _minimal _untargzpdf(){ )'
> untargzpdf

I guess this is probably some kind of corner case or what I usually do with alias is not really correct/orthodox 😅

Thanks

oh that's intereseting, i think right now the code just naively takes the first "word" of the alias as the actual command, but yours is more complicated than that, would probably have to start doing the bash parsing on the alias

Ah ok, it make sense then why it's behaving this way but honestly I don't know if it is worth the time to add the alias parsing.

In the end I worked around the issue by defining just the function instead of the alias.
So just doing this works basically the same for me:

untargzpdf(){
                            tar -xvzf $1 --wildcards '*.pdf';
                        }

Thanks for the answer !
