accessing cljs code from inside a macro

[Yehonathan Sharvit]

I would like to write a macro that calls a cljs function.
The problem is that the macro is defined inside a clj file and when I require the namespace that contains the cljs code I receive the following compilation error:

Caused by: java.io.FileNotFoundException: Could not locate user__init.class or user.clj on classpath:

This is my code snippet:

(ns cljs_explore.macros
(:require [user :as user]))

You can't load CLJS namespaces from clojure, you'll have to fully-qualify CLJS symbols inside the emitted macro code, eg https://github.com/clojure/core.async/blob/master/src/main/clojure/cljs/core/async/macros.clj?MobileOptOut=1#L16

Can you be a little more clear as to what you are doing? If you are literally trying to call a ClojureScript function from Clojure, it will not work. However, it is possible to resolve ClojureScript symbols from Clojure for the purposes of macro code generation but you'll need to use the ClojureScript analyzer to do this.

I am trying to write a macro that calls cljs code.
How can I use the ClojureScript analyzer to resolve ClojureScript symbols from Clojure?

For example I have:

a cljs namespace

(ns user.my-cljs)

(defn foo [] 4)

a clj namespace

(ns my-macros)

(defmacro my-macro [] my-cljs/foo)

What is the best way to access my-cljs/foo from inside the macro?

What do you mean by "access"? Do you mean the actual source code for the symbol?
