Is there something like (describe-spec :my/spec) that will print what :my/spec is about? Maybe recursively. Loosely analog to macroexpand/`macroexpand-all`

doc works on registered specs

it is, however, not deep/recursive

(doc :my/spec)

Hi all, can someone help me with spec’ing a higher-order fn? One of the arguments to a fdef is a higher order fn that I’ve defined as:

(s/def ::foo-fn (s/fspec :args any? :ret ::foo)) 

:args (s/cat) is prob best

fspecs are instrumented by generating args and invoking the passed function a bunch of times

this is sometimes surprising and/or bad for people

an alternate option to using an s/fspec here is to just spec it as ifn?

@alexmiller Will try those out! Thanks!!

…Using :args (s/cat) instead of any? definitely sped things up.. Can’t use ifn? for my specific use case but still generating / running through my system about 5 results per second which is pretty fast. …just spoiled by how fast test.check usually runs data!

any? can generate very large nested colls

(s/cat) can only generate one thing, ()

yes.. I knew that any was slowing things down but couldn’t figure out how to do no args… Didn’t think to try (s/cat) so thanks for that!
