error in clojurescript

[pbrito]

Hi,
I'm beginning to use spec with clojurescript.
But I can't use this library.
s/explain works but not expound

cljs.user=> (expound/expound :example/place {})

#object[TypeError TypeError: Cannot read property 'cljs$lang$applyTo' of undefined]
TypeError: Cannot read property 'cljs$lang$applyTo' of undefined

Thanks for reporting this bug!

In order to help me track down the problem, can you please let me know:

1. Your version of Clojure
2. Your version of Clojurescript
3. Your version of org.clojure/spec.alpha (if any)
4. The 'require' statement for expound.

Thanks!

I run the project with 'rlwrap lein figwheel'

lein -v                                                                                                                                                              
Leiningen 2.7.1 on Java 1.8.0_45 Java HotSpot(TM) 64-Bit Server VM

Dependencies in project.clj

  :dependencies [ [org.clojure/clojure "1.9.0-alpha12"]
                  [org.clojure/clojurescript "1.9.671"]
                  [expound "0.1.0"]]

  :plugins [[lein-figwheel "0.5.8"]]

In the repl I do
(require '[cljs.spec.alpha :as s])
instead of
(require '[clojure.spec.alpha :as s])

So when I use spec it goes well:

hello.core=> (s/explain :example/place {})
val: {} fails spec: :example/place predicate: (contains? % :city)
val: {} fails spec: :example/place predicate: (contains? % :state)
:cljs.spec.alpha/spec  :example/place
:cljs.spec.alpha/value  {}

But expound

hello.core=> (expound/expound :example/place {})
#object[TypeError TypeError: Cannot read property 'cljs$lang$applyTo' of undefined]

Thanks for the details! I am having trouble getting lein-figwheel 0.5.8 to work, but I can reproduce with that version of Clojure, Clojurescript and figwheel 0.5.11. I'm not sure what's going on - there seems to be some change in recent versions of Clojurescript where goog.string is not being loaded properly. I don't see the same problem on Clojurescript 1.9.542, but I realize that's not a great workaround. I'll see if I can figure out the issue tomorrow.

I think I may have discovered a fix. Can you try the following:

1. Clone this repo
2. cd into the main dir
3. lein install
4. In your test project's project.clj, change [expound "0.1.0"]] to [expound "0.1.1-SNAPSHOT"]]
5. Let me know if it is fixed :)

error:
Could not find artifact expound:expound:jar:0.1.1-SNAPSHOT in clojars

[bhb]

@pbrito That's correct: I haven't yet pushed it to Clojars. However, the lein install step should install it for you locally (once you have pulled down this repo). Did you get any errors when running lein install?

[pbrito]

Sorry! I didn't follow your instruction.

So, after following your instructions, I was able compiled without errors:

Wrote /Users/paulo/clojure/specT/expound/pom.xml
Installed jar and pom into local repo.

And using expound "0.1.1-SNAPSHOT" in my project returned:

dev:hello.core=> (expound/expound :example/place {})
-- Spec failed --------------------

  {}

should contain keys: `:city`,`:state`

-- Relevant specs -------

:example/place:
  (cljs.spec.alpha/keys
   :req-un
   [:example.place/city :example.place/state])

@pbrito Thanks very much for confirming the fix! I'll release a new version with this fix sometime tonight.

Fixed with 131d86c

@pbrito Should be fixed in version [expound "0.1.1"] (now on Clojars). Thanks for the bug report!
