Hi
Here's another macro-noob question. (Thanks for the help on the
previous question and please do let me know if stackoverflow is a more
appropriate place to ask noob questions.)
I'm trying to write a macro (or a function) that defines/declares
specifically named functions. In (let [eff "gee"] (foo eff)) I want
the macro foo to define/declare a function called foo-gee, not foo-
eff. What should I do differently?
First attempt:
(defmacro foo [x]
(let [name# (symbol (str "foo-" x))]
`(defn ~name# [] ())))
(let [eff "gee"] (foo eff))
=> #'user/foo-eff
Second attempt:
(defmacro foo [x]
`(let [name# (symbol (str "foo-" ~x))]
(defn name# [] ())))
(let [eff "gee"] (foo eff))
=> #'user/name__4807__auto__
Third attempt:
(defmacro foo [x]
`(let [name# (symbol (str "foo-" ~x))]
(defn ~name# [] ())))
(let [eff "gee"] (foo eff))
=> First argument to def must be a Symbol
