The path is the series of tags you've traversed through the spec (when there are parts in :or :alt :cat etc).
We will have more documentation on it but we've held off because it was changing pretty regularly in early alphas. A spec for the current explain-data is something like this (I'm just typing this in, so could be a bit off): ;; path is a stack of parts, which refer to tags in schemas (s/def ::part simple-keyword?) (s/def ::path (s/coll-of ::part :kind vector?)) ;; pred is a symbol, a set, or a function, but being lazy here (s/def ::pred any?) ;; the failing data value (s/def ::val any?) ;; via is a stack or schema identifiers (s/def ::schema-key qualified-ident?) (s/def ::via (s/coll-of ::schema-key :kind vector?)) ;; in is a stack of keys in nested data (s/def ::data-key any?) (s/def ::in (s/coll-of ::data-key :kind vector?)) ;; some of these may be required, I would have to analyze the code further (s/def ::problem (s/keys :opt-un [::path ::pred ::val ::via ::in])) (s/def ::problems (s/coll-of ::problem :min-count 1)) ;; added when macroexpand args check fails (s/def ::args (s/coll-of any?)) (s/def ::explain-data (s/keys :req [::problems] :opt [::args])) On Tuesday, August 23, 2016 at 2:33:34 PM UTC-5, puzzler wrote: > > On Tue, Aug 23, 2016 at 7:45 AM, Alex Miller <a...@puredanger.com> wrote: > >> We expect Clojure users to become familiar with spec and its output as it >> is (now) an essential part of the language.
