How to use slurp from ClojureScript

slurp.clj

(ns foo.core
  (:refer-clojure :exclude [slurp]))

(defmacro slurp [file]
  (clojure.core/slurp file))

;; In CLJS

(ns bar.core
  (:require [foo.core :include-macros true :refer [slurp]]))

;; This is possible because we can evaluate *Clojure* code at compile time.
(def project-clj 
  (slurp "project.clj"))

@FrankApiyo ClojureScript uses Clojure to expand macros. This means the code inside the slurp macro above is being invoked in the Clojure environment and, thus, all of the usual Clojure functions are available. In this case, slurp will return the content of project.clj as a string and "inline" it on line 14.

So if project.clj looked like

(defproject foo)

then line 13 to 14 expands to

(def project-clj
  "(defproject foo)")
