Hello --
I am trying to gain a better understanding of Clojure's macro
language.
The output I am aiming for (and which is to be used as code in another
macro) is as follows:
{:a a :b b :c c :d d}
The attempt I made is as follows:
(defmacro tm [& args]
`{~@(mapcat (fn [x] (list (keyword x) x)) args)})
Obviously, I am making a very basic mistake, because at the REPL I
get:
---
user=> (defmacro tm [& args]
`{~@(mapcat (fn [x] (list (keyword x) x)) args)})
java.lang.ArrayIndexOutOfBoundsException: 1
java.lang.Exception: Unmatched delimiter: )
---
Any pointers are greatly appreciated.
Ingolf
