Namespace question and request for project with non-trivial use of clojure.spec

[Jonathon McKitrick]

I've run into some odd namespace issues with clojure.spec, and I'm sure it's because I'm doing something wrong. I have this in my ns declaration:

[foo.schema :as schema]

However:

foo.main> (s/valid? :foo.schema/email "f...@bar.com")
true
foo.main> (s/valid? :schema/email "f...@bar.com")
Exception Unable to resolve spec: :schema/email  clojure.spec/reg-resolve! (spec.clj:68)
foo.main>

It would also be useful if I knew of a non-trival project I could view that uses clojure.spec across namespaces, but without being SO complex that the basics are obscured.

Does anyone know of or have an example?

You want an auto-resolved keyword here to take advantage of the alias:  ::schema/email. Single colon will just be the literal namespace you write.

That did the trick. Thanks!

Although I can’t recall off the top of my head any example applications that demo non-trivial spec usage, you might be able to find some good projects using CrossClj: https://crossclj.info/ns/org.clojure/clojure/1.9.0-alpha14/project.clj.html#used. (There’s a good chance that any project that’s using one of the alpha releases of Clojure 1.9 is doing so for spec.)
