ClojureScript - How to load user.cljs file for repl sessions

I'm starting a cljs repl with a node.js environment.

=> clj -m cljs.main -re node

Documentation for using the repl says that you can place a user.cljs file at the classpath root for the project and it will be automatically loaded into a repl session in the cljs.user namespace.

I have a src directory with user.cljs at its base. The project's directory structure looks like the following.

xyz / deps.edn
    / src / xyz / core.cljs
          / user.cljs

ClojureScript version 1.10.520 is the only dependency in deps.edn.

Whenever I start the repl I get the following error.

Execution error (IllegalArgumentException) at cljs.closure/compile-file (closure.clj:639). /var/folders/rk/r65ng3n93l53h95nsvkl265c0000gn/T/out385499094487053918164582825852/cljs/user/user5D28A44.js is not a relative path

When I look in the temporary output folder it is clear that ../cljs/user/user5D28A44.js is not being generated.

Is this a cljs bug? Can someone show me an example of this working correctly?

You have to start the ClojureScript repl explicitly from clojure programmatically, the command line startup short hand doesn't work for loading user.cljs.

=> clj
Clojure 1.10.1
user=> (require '[cljs.repl :as repl])
user=> (require '[cljs.repl.node :as node])
user=> (def env (node/repl-env))
user=> (repl/repl env)
cljs.user=> working?
"Yes."
cljs.user=> ...

With the working? symbol defined in user.cljs it is available as you would expect.

It’s a known issue. See: CLJS-2917

You can work around it by specifying an output directory via -d.
