How to print bash function in one line?

[Peng Yu]

Hi,

Bash functions shown by declare -f may not be readily changed to one
line format.

$ declare -f f
f ()
{
    x=
}

In the above example, if I fold the output in one line, it would be
the following code, which is not valid in bash.

f () { x= }

While I could add ; manually to make it work for a specific example,
but I am not sure adding ; to each line would be a viable option. I'd
rather only add ; only when necessary.

Is there a way in bash to print a function definition in one line format?
