Hi, I've written a macro to build inline expanded math expressions and
it's working well in Clojure, however fails with a compile exception
in CLJS. I'm not sure if this is a shortcoming of the CLJS compiler or
(much more likely) a mistake with my macro.
(ns macromath.core)
(defmacro defmathop
"Constructs a macro to build inlined nested expressions with f applied
to inner pairs and f2 to combine results."
[name f f2]
`(defmacro ~name
([a# b# c#] `(~~f2 (~~f ~a# ~b#) ~c#))
([a# b# c# d#] `(~~f2 (~~f ~a# ~b#) (~~f ~c# ~d#)))))
(defmathop add + +)
(defmathop sub - -)
(defmathop mul * *)
(defmathop div / /)
(defmathop madd * +)
(defmathop msub * -)
(defmathop addm + *)
(defmathop subm - *)
lein repl
(use 'macromath.core)
(madd 2 3 4)
; 10
(madd 2 3 4 5)
; 26
My short CLJS test is as follows:
(ns macromath.test
(:use-macros [macromath.core]))
(defn ^:export main
[]
(.log js/console (madd 2 3 4 5)))
lein cljsbuild fails with this exception:
Caused by: java.lang.IllegalArgumentException: No method in multimethod
'emit-constant' for dispatch value: class clojure.core$_PLUS_
How can I rewrite the macro so it properly works with the CLJS compiler?
Thank you!
