schpec

Schpec is a utility library for clojure.spec.

Obtention

Note that schpec will not attempt to be stable until clojure.spec is stable.

[com.gfredericks/schpec "0.1.2"]

Things it has

In the com.gfredericks.schpec namespace:

• xor: like s/or but values can only match exactly one spec
• excl-keys: like s/keys, but does not allow extra keys
• alias: like clojure.core/alias, but can alias to non-existing namespaces

com.gfredericks.schpec.defn+spec/defn

A variant of defn that allows annotating args with specs, and overloading function clauses with specs. Tries each clause in order.

E.g.,

(defn+spec/defn thomas
  ([a :- integer?, b :- boolean?]
   [:int-and-bool a b])
  ([a b]
   [:any-two-args a b])
  ([a b c :- integer? d & more]
   [:four-args-1-int+varargs a b c d "here's the varargs ->" more])
  ([a b c d]
   [:any-four-args a b c d]))

Things it could have if it had them

It is currently empty but is intended to be a home for all manner of things, such as:

• other common specs
• generators related to specs
• other helper functions/macros for defining specs
• whatever other feature you miss from plumatic/schema
• etc.

Contributing

Pull requests! I welcome anything related to clojure.spec that is at least half-baked. Sufficiently weird things will be relegated to sufficiently obscure namespaces.
