I define a record (defrecord point [x y])and the following macro: (defmacro drg [typename components] `(def ~(symbol (str typename "-" (str (first components)))) (fn [~(symbol "obj")] (get ~(symbol "obj") ~(symbol (str ":" (str (first components))))))))
But calling the macro results in an error message: user> (drg point [x y]) CompilerException java.lang.RuntimeException: Unable to resolve symbol: :x in this context, compiling:(NO_SOURCE_PATH:1) Can anyone tell me what my mistake is?
I guess the problem is that you created :x using symbol, so it is not recognized as a key.
But the whole approach, starting with creating names to def to inside a macro, is troublesome. This makes it hard to follow what's going on. If you provide a larger context of what you are trying to accomplish, I'm sure someone can suggest a much better approach.
