->mapclj/smacro
(->map & ks)Like {} but can omit keys when you want it to be the same as the symbol
bound to the value. Useful for avoiding unnecessary repetition during map
construction. At >9 key-value pairs, switches from an array-map to
a hash-map just like {}.
(let [[a b c d] (range)]
(->map a b :c1 c d))
;; => {:a 0, :b 1, :c1 2, :d 3}
Like `{}` but can omit keys when you want it to be the same as the symbol
bound to the value. Useful for avoiding unnecessary repetition during map
construction. At >9 key-value pairs, switches from an array-map to
a hash-map just like `{}`.
(let [[a b c d] (range)]
(->map a b :c1 c d))
;; => {:a 0, :b 1, :c1 2, :d 3}assoc*clj/s
(assoc* m & kvs)Like clojure.core/assoc, but won't assoc if key or val is nil.
Like `clojure.core/assoc`, but won't assoc if key or val is nil.
contrastclj/s
(contrast op)(contrast op obj & objs)Contrast multiple comparable objects with each other with op. (Wrapper
around clojure.core/compare.) Example ops: < > <= >= = not=
Contrast multiple comparable objects with each other with op. (Wrapper around `clojure.core/compare`.) Example ops: < > <= >= = not=
deep-mergeclj/s
(deep-merge & colls)Like clojure.core/merge, but recursively merges maps.
Like `clojure.core/merge`, but recursively merges maps.
deep-merge-withclj/s
(deep-merge-with _ coll)(deep-merge-with f c1 c2)(deep-merge-with f c1 c2 & cs)Like clojure.core/merge-with, but recursively merges maps.

derefable?clj/s
(derefable? ref)Returns true if clojure.core/deref can be called on ref.
Returns true if `clojure.core/deref` can be called on ref.
dissoc-inclj/s
(dissoc-in m [k & ks])Dissociates an entry from a nested associative structure returning a new nested structure. ks is a sequence of keys. Any empty maps that result will not be present in the new structure.
Dissociates an entry from a nested associative structure returning a new nested structure. ks is a sequence of keys. Any empty maps that result will not be present in the new structure.
expectclj/smacro
(expect data pred)(expect data pred msg)Perform an assertion against a predicate. Returns data on success.
(-> {:status 200, :body "Foo bar"} (expect (comp #{200 201 202} :status) "HTTP response status code was not successful.") :body)
Perform an assertion against a predicate. Returns `data` on success.

Implementation detail of the `expect` macro. Do not use this directly.
expectationclj/smacro
(expectation pred)(expectation pred msg)Constructs and returns an assertion function that checks input against a predicate, returns given input on success.
(def successful-resp? #(<= 200 % 299))
(def fetch
(comp :body (expectation successful-resp?) http/get))
(-> "https://example.com" fetch :body)
Constructs and returns an assertion function that checks input against
a predicate, returns given input on success.
(def successful-resp? #(<= 200 % 299))
(def fetch
(comp :body (expectation successful-resp?) http/get))
(-> "https://example.com" fetch :body)in?clj/s
(in? coll elm)Returns true if coll contains elm.
Returns true if coll contains elm.
macro-body-optsclj/s
(macro-body-opts [opts & body :as params])Helper for creating macros that accept an optional map of options in their body. Call this function in your macro on the rest-body param and it will return a vector containing the option map and the rest of the body.
An option map will be found if there were more than one form in the body and the first form is a map.
