In theory, not very difficult. Something like
(defmacro defn [name everything-else]
`(clojure.core/defn
~(with-meta name {:source `(defn ~name ~@everything-else)})
~@everything-else))
(which gets clojure.core/defn to do all of the heavy lifting) should
work if putting the metadata on the Var suffices.

Re: Pretty print 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 want your fn's to be re-serializable (which I don't think you do), you have to spell out which fn you're using. https://github.com/weissjeffm/serializable-fn Another caveat is that it does not work with defn, just fn. So you would have to do (def qw (fn [] (inc 2)) A serializable.fn/defn would be really nice to have, I am not sure how difficult it would be to write, without having tried it. -jeff On Friday, March 2, 2012 10:19:56 PM UTC-5, Phil Hagelberg wrote: Mark Rathwell mark.rathw...@gmail.com writes: (clojure.repl/source-fn 'qw) will give you the source.

Re: Pretty print defn
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?

Re: Pretty print defn
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.
