Hi everyone, I wanna spec sth like this :

[[:__      :TXC    :BTC    :ALT    :PAXG   ]
 [:TT1     0M      0M      0M       0M     ]
 [:TT2     0M      0M      0M       0M     ]
 [:TT3     0M      0M      0M       0M     ]
 [:TT4     0M      0M      0M       0M     ]
 [:Others  0M      0M      0M       0M     ]
 ]

but the following spec won't work :

(spec/def ::X-Header-Row     (spec/cat :dont-care #{:__} :exposure-id-s (spec/+ ::Exposure-ID)))
(spec/def ::X-Row            (spec/cat :g-id ::Group-ID :weights (spec/+ decimal?)))
(spec/def ::X                (spec/cat :header ::X-Header-Row  :rows (spec/+ ::X-Row)))

What is it that I'm not getting about how spec/cat works and how can I spec that table ? Thanks a lot in advance

won't work .... because?

regex ops combine to spec one collection, so you need to do something to separate the outer collection and the inner collection "levels"

Alex Miller (Clojure team)17:10:26

probably the shortest path to that is to wrap s/spec around the ::X-Row cat

Thanks a lot, Alex
