hey, is there a way to reuse the same spec for different map keys without having to redefine them over and over?

(s/def ::address (some-pred-to-check-ethereum-addr))

(s/def ::tx (s/keys :req-un [:sender ::address  ;; apply address spec to :sender 
                             :recipient ::address])) ;; apply address spec to :recipient 

In short, no

@wcalderipe you can do this:

(def spec (s/....)
(s/def ::a spec)
(s/def ::b spec)

Note sure if that also works in spec2 - I completely lost track of that

No, it won’t like that but you could set it quoted and make it work via s/register

But I don’t think that works the way it’s requested with req-un in either case

thanks @alexmiller and @borkdude

I think select might work better here right in spec2?

s/keys is the best way to check the shape of a map?

For stuff like above, yes
