Congratulation. I am getting one problem for defmacro spec with defmethod.
Here it is
(defmulti mycomp (fn [v] v))
(defmacro defcomp [m]
`(defmethod mycomp ~m
[_]
~m
)
)
(defcomp :test) ;; Throwing exception
;; Expand macro
(defmethod mycomp :test [_] :test)
;; it is working
Here is error details
Call to clojure.core/fn did not conform to spec: In: [0 0] val:
(com.mxsys.psql.component/_) fails spec:
:clojure.core.specs.alpha/arg-list
at: [:args :bs :arity-1 :args] predicate: (cat :args (*
:clojure.core.specs.alpha/binding-form) :varargs (? (cat :amp #{(quote
&)}
:form :clojure.core.specs.alpha/binding-form))), Extra input In: [0 0]
val:
com.mxsys.psql.component/_ fails spec:
:clojure.core.specs.alpha/arg-list at:
[:args :bs :arity-n :args] predicate: vector?
