Hi everyone,
I cannot figure out for the life of me how to pass in an optional
doc-string into a 'defsomething' macro and have it to work. If I
hard-code it then it works just fine...
(defmacro def-plus-doc [name & syms]
`(def ~(with-meta name (assoc (meta name) :doc "HI!")) ~@syms))
;;this will work just fine
(defmacro def-plus-doc [name & syms] ;;slightly augmented to detect
doc-string
`(let [[doc# & syms# :as all#] (vector ~@syms)
cs# (if (string? doc#) [syms# true] [all# false])
ds# (if (second cs#) doc# "This workflow has not been
documented...")]
(def ~(with-meta name (assoc (meta name) :doc ds#)) ~@syms)))
;;fails with CompilerException java.lang.RuntimeException: Unable to
resolve symbol: ds# in this context, compiling:(NO_SOURCE_PATH:5:26)
why is it so hard? I've been trying for almost 3 hours!!!! nothing seems
to work... :(
Jim
