Hi, Alex, thanks for the responsiveness. The paths refer to tags in the schemas, not keys in the map. However, this > has been asked about several times today and Rich has added support for a > :in clause that will track the key paths to master and that will be in > alpha2. >

So, to write a translator from a Spec to the approximate json or avro schema it specifies, or translate from a Spec to a function that coerces a String to a data structure that conforms, I would have to: 1. Parse the output of 'describe' back into a description of the Spec's internals (if I can get at all of them) 2. Interpret / translate the parsed tree In fact, the current Spec protocol, in my mind, is actually 4 protocols, one for 4 different translators you all have written: (defprotocol Spec ;; Spec->Conformer (conform* [spec x]) :: Spec->Explainer (explain* [spec path via x]) ;; Spec->Gen (gen* [spec overrides path rmap]) (with-gen* [spec gfn]) ;; Spec->Describer (describe* [spec])) But this implementation hiding dooms clojure/core to write *all* the translators. This just seems weird given how most other Clojure features are open and user-extensible. --Leif -- You received this message because you are subscribed to the Google Groups "Clojure" group.
