Re: Confusion with doc macro
It uses (meta (var common/basic-logger)).

I'm a bit confused by what the doc macro is doing. Doesn't it simply

I try this at the REPL:

nil
For the following item:
user= (meta common/basic-logger)
{:ns #Namespace decorators.common, :name basic-logger, :file
decorators/common.clj, :line 13, :arglists ([f]), :doc This is a
very basic logging decorator.}
Shouldn't I see something like this:

decorators.common/basic-logger
([f])
This is a very basic logging decorator.
nil
Any help would be great.

Re: Confusion with doc macro
Okay, then I need a hand with something then. I'm trying to come up
with a macro that does the following:
(defmacro def-with-meta ...) - You supply this
(def-with-meta symbol init)
(= (meta (var symbol)) (meta init)) - True
Any suggestions folks?

Re: Confusion with doc macro
def already adds metadata on the symbol as metadata on the var. Did
you need more than this (below)?
user (def ^{:doc foo} x [1 2 3])
#user/x
user (meta (var x))
{:ns #Namespace user, :name x, :doc foo, :line 1, :file NO_SOURCE_FILE}
user (doc x)
-
user/x
foo
nil
user (defn ^{:doc foo foo} xx [] (println hello))
#'user/xx
user (meta (var xx))
{:arglists ([]), :ns #Namespace user, :name xx, :doc foo foo,
:line 1, :file NO_SOURCE_FILE}
user (doc xx)
-
user/xx
([])
foo foo

Re: Confusion with doc macro
No, I'm looking for a copy meta routine.
The mysterious defmeta macro does this, in one call.
(defmeta a map)
(= (meta (var a)) (meta map))

The mysterious defmeta macro does this, in one call.
(defmeta a map)
(= (meta (var a)) (meta map))
This will do what you want, but I would not advise using it:
(defmacro def-with-meta [symbol init]
`(let [m# (meta ~init)]
(def ~symbol ~init)
(reset-meta! (var ~symbol) m#)
(var ~symbol)))
Then:
(= (meta (var symbol)) (meta init)) ;= true
(= (meta (var symbol)) (meta symbol)) ;= true
