How to show content of a function in fish?

Question

In fishshell, I can create and save a function very easy, like:

function aaa
   echo hello
end

funcsave aaa

But how to view the body of the function aaa from command line easily? Is there any way other than:

echo ~/.config/fish/functions/aaa.fish

Answer 1

invoke functions aaa on command line

username@MacBook-Pro ~> functions aaa
function aaa
    echo hello
end
username@MacBook-Pro ~>

Some more uses of functions command

functions -n
# Displays a list of currently-defined functions

functions -c foo bar
# Copies the 'foo' function to a new function called 'bar'

functions -e bar
# Erases the function `bar`

Answer 2

Also, type aaa will show you the function definition, with a bit of a preamble:

$ type aaa
aaa is a function with definition
function aaa
    echo hello
end
