:foreign-libs with module conversion does not works properly if it is used form deps.cljs


    • Type: Bug
    • Status: Closed
    • Priority: Minor
    • Resolution: Completed
    • Affects versions: 1.9.76, 1.9.36
    • Fix versions: None
    • Environment:

      Linux, openjdk8

    • Patch:


      When :foreign-libs is used for consume commonjs (or amd) modules from clojurescript using the `deps.cljs` mechanism, an unexpected "internal compiler error" is raised. When the same configuration is attached on the build script, everything works as expected.

      Simple way to reproduce that, create sample directory tree:

      mkdir tmp;
      cd tmp;
      mkdir -p src/testapp
      mkdir -p src/vendor
      touch src/testapp/core.cljs
      touch src/vendor/greeter.js

      Download the latest compiler or copy the recently build one from master:

      wget https://github.com/clojure/clojurescript/releases/download/r1.9.36/cljs.jar

      Create the sample cljs file:

      ;; tmp/src/testapp/core.cljs
      (ns testapp.core
        (:require [cljs.nodejs :as nodejs]
                  [greeter.core :as g]))
      (defn -main
        [& args]
        (println (g/sayHello "Ciri")))
      (set! *main-cli-fn* -main)

      Create the sample commonjs module:

      "use strict";
      exports.sayHello = function(name) {
        return `Hello ${name}!`;

      Create the build script (that works):

      ;; tmp/build.clj
      (require '[cljs.build.api :as b])
      (b/build "src"
       {:main 'testapp.core
        :output-to "out/main.js"
        :output-dir "out"
        :target :nodejs
        :language-in  :ecmascript6
        :language-out :ecmascript5
        :foreign-libs [{:file "vendor/greeter.js"
                        :module-type :commonjs
                        :provides ["greeter.core"]}]
        :verbose true})

      And compile this using the following command:

      java -cp cljs.jar:src clojure.main build.clj

      This will generate successfully the final artifact that can be successufully executed with node:

      node out/main.js
      # => "Hello Ciri!"

      But, if you remove the `:foreign-libs` from the build script and create a new `src/deps.cljs` file
      with the following content:

      {:foreign-libs [{:file "vendor/greeter.js"
                       :module-type :commonjs
                       :provides ["greeter.core"]}]}

      And try compile it:

      $ java -cp cljs.jar:src clojure.main build.clj
