In theory, not very difficult. Something like
(defmacro defn [name & everything-else]
`(clojure.core/defn

I use serializable.fn pretty extensively, and it's been working great for
me. I think at this point, the only fix I put in that Phil didn't is that
my serialized fn's print with an unqualified "fn" symbol, instead of
"serializable.fn/fn". I did that so it's more readable, the tradeoff is
that
If you are just printing it to the screen, print or println will do
what you want. There shouldn't be a need for a pretty printer, the
source is already formatted exactly as it was written.

Thank you for your help! :)
I managed to get repl/source-fn to read source from external namespace. But
print gives me
"(defn buy? [today]\n (and\n(not (nil? today))\n"
Everything on one line with "\n" instead of new lines. Shouldn't pretty
print handle this?

You can also use serializable-fn to create a function that will carry
its source around with it in metadata:
https://github.com/technomancy/serializable-fn
But it's not very well tested.

Hi.
Is it possible to pretty print a source code of the function defined
with defn? I have tried the following:
(defn qw []
(inc 2))
(with-pprint-dispatch code-dispatch (pprint qw))
And got #. But I would like to get at least
"(inc 2)". Is it possible at all?
