Re: clojure.spec and generic map with couple of special keys
If I'm not mistaken, similar issue was recently discussed on the
Clojurians Slack (direct link -
https://clojurians.slack.com/archives/clojure-spec/p146738221722 ,
archive link -
https://clojurians-log.clojureverse.org/clojure-spec/2016-07-01.html -
discussion starts from @ghadi's post at 17:10:00).
The basic idea is to validate namespaced keywords first, remove them
using the conformer, and then validate rest of the keys.

But how do I write a spec to validate them when they are in a single
map?
I tried to use s/every but then another problem popped up: how do I
reference or check another spec from inside s/every predicate? In my
case, values are more complex than string? and have their own spec.
Please help

I ran into this same issue while trying to spec Clojure's destructuring

clojure.spec and generic map with couple of special keys
Imagine I have a generic keyword => string map with a special key that
stores a number:
{ ::count 7
:x "x"
:y "y"
:z "z"
... }
Both cases are easy to validate on their own:
(s/def ::count number?)
(s/conform (s/keys ::count) { ::count 7 })
(s/conform (s/map-of keyword? string?) { :x "x", :y "y", :z "z" })
But how do I write a spec to validate them when they are in a single map?
I tried to use s/every but then another problem popped up: how do I
reference or check another spec from inside s/every predicate? In my case,
values are more complex than string? and have their own spec.
