uk.axvr.refrain — uk.axvr/refrain 0.1

Collection of useful Clojure utilities.

assoc* clj/s

(assoc* m & kvs)

Like clojure.core/assoc, but won't assoc if key or val is nil.

contrast clj/s

(contrast op)

(contrast op obj & objs)

Contrast multiple comparable objects with each other with op. (Wrapper around clojure.core/compare.) Example ops: < > <= >= = not=

deep-merge clj/s

(deep-merge & colls)

Like clojure.core/merge, but recursively merges maps.

deep-merge-with clj/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.

dissoc-in clj/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.

in? clj/s

(in? coll elm)

Returns true if coll contains elm.

macro-body-opts clj/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.

read-edn-resource clj

(read-edn-resource path)

Read an EDN file at path from JVM resources.

regexp? clj

(regexp? x)

Returns true if x is a Java regular expression pattern.

submap? clj/s

(submap? map1 map2)

Returns true if map1 is a subset of map2.

trim-end clj/s

(trim-end s substr)

Trim substr from the end of s.

trim-start clj/s

(trim-start s substr)

Trim substr from the start of s.

when-let* clj/s macro

(when-let* bindings & body)

Short circuiting version of clojure.core/when-let on multiple binding forms.
