How to remove functions from fishshell without deleting the function file directly?

Question

I've defined a function hello in fishshell:

function hello
    echo Hello
end

And save it:

funcsave hello

If I want to delete it, I can delete the file ~/.config/fish/functions/hello.fish.

Is there any other way to do it? (like built-in funcdel or funcrm)

Answer 1

No, there isn't any builtin to remove the file, but you can use:

functions --erase hello

or

functions -e hello

to erase the function definition from the current session.

Answer 2

I created another fish function for that

function funcdel
    if test -e ~/.config/fish/functions/$argv[1].fish
        rm ~/.config/fish/functions/$argv[1].fish
        echo 'Deleted function ' $argv[1]
    else
        echo 'Not found function ' $argv[1]
    end
end
