Fish how to prevent recursive function calls

Question

How can I prevent recursive function calls on fish functions when overriding a default binary with a function that has the same name ?

eg.

# Override 'ls'
function ls
    if [ my_special_condition ]
        * Do special stuff *
    else  # Call regular ls
        ls $argv
    end    
end

Obsiously the above code ends up in a resursive loop without calling the actual 'ls' binary. Is there a way to fix this ?

Answer 1

I understand that you want to replace the ls function while also being able to call the original. You can do that by copying the function via functions -c:

functions -c ls orig_ls # copies ls to orig_ls
function ls
    if [ my_special_condition ]
        * Do special stuff *
    else  # Call original ls
        orig_ls $argv
    end    
end
