ClojureScript

Asserts still fail while :require-ing .js file (either in :libs or in :source-paths) (same as CLJS-1196)

Description

Following on CLJS-1196, I can't get it to work.

In version 0.0-3264 lein-cljsbuild crashed on weird eception `Caused by: java.lang.IllegalArgumentException: No implementation of method: :make-reader of protocol: #'clojure.java.io/IOFactory found for class: nil"` but the current version 0.0-3269 gives the same failed assertion as previously.

I've put up a sample project to illustrate the issue.

Steps to reproduce:

`git clone https://github.com/tillda/stackone`
`cd stackone`
`git checkout 537e5c69b844bc53c159e85cafc24310543cc918`
`lein clean && lein cljsbuild once temp`

Expected behaviour: cljs compiled successfully with src/vendor/client/closure.js and env/stackone/helpersjs.js being included.

Actual behaviour:

```
Compiling "resources/public/lein-cljsbuild-temp/dev-mode-deps.js" failed.

This issue is in danger of being closed. Please supply minimal steps to reproduce that do not involve anything other than the ClojureScript compiler. We no longer have time to wade through the indirection introduced by cljsbuild or any other downstream tooling. Thanks.

@David Nolen: I have created a failing minimal testcase based on the Quick Start document. Here it is: https://github.com/tillda/cljs-testcase/

Michal the failing example is not correct. You are not supplying any :libs option.

Ah! Thank you very much! This additional issue was therefore my error. Now it seems to work even in my "big" example.

However it would be cool if there was a meaningful error message stating that a file path can't be resolved. If one is not an expert in the cljs compiler this is almost impossible to figure out. After all the error message in the CLJS-1196 issue and in this wrongfully reported one are exactly the same.

You may close this issue.

We'll leave it open for the improving the error message.

Added the check in cljs.closure/source-on-disk where there is info for the error message.

For the supplied case, the error message is:

java.lang.IllegalArgumentException: The file file:/home/carlos/Playground/cljs-testcase/src/hello_world/closure.js 
lacks an associated source file. If it is a JavaScript library please add it to :libs}}

If a different wording or location of the check is needed, I'll submit a new patch with corrections.

Notes:

  • Changed:(:provides js) to (-provides js) in order to be consistent with IJavaScript.
  • cljs.clojure/source-on-disk takes a js argument that should satisfy with IJavaScript and ISourceMap if :source-map is enabled but the implementation is hardcoded to maps because :source-map and :source-url are used instead of ISourceMap methods -source-map and -source-url. I propose to extend PersistentMap and PersistentArrayMap to ISourceMap to make source-on-disk compliant with both protocols.
