The easiest way to use expectations in your own projects is via Leiningen. Add the following dependency to your project.clj file:
[jry "1.0.0"]
To build expectations from source, run the following commands:
lein deps
lein jar
composing functions
; % as a shorthand for partial
((% identity 1)) => 1
interop related functions
; truthy converts truthy values to true and falsey values to false
; good for functions that need to return true or false explicitly
(truthy? "BRN") => true
(truthy? true) => true
(truthy? nil) => false
; falsey is the complement of truthy
(falsey? "BRN") => false
(falsey? true) => false
(falsey? nil) => true
; obj->map allows you to convert from a Java object to a map
; without using reflection
(obj->map (java.util.Date. 2012 0 31)
:month .getMonth
:year .getYear
:day .getDate) => {:month 0 :year 2012 :day 31}
; parse-double & parse-long are available, and helpful when used with high-order fns
(parse-double "2.1") => 2.1
(parse-long "2") => 2
collections
; every is like every?, but it returns the entire list if
; everything is truthy; else, nil
(every identity [1 2 3]) => [1 2 3]
(every identity [1 false]) => nil
maps
; submap returns true if a map is (recursively) a submap
(submap {:a 1 :b {:c 2}} {:a 1 :b {:c 2 :d 3} :e 4}) => true
(submap {:a 1 :b {:c 2}} {:a "9" :b {:c 2 :d 3} :e 4}) => false
(submap {:a 1 :b {:c 2}} {:a 1 :b {:c "9" :d 3} :e 4}) => false
; flatten-keys denormalizes keys.
(flatten-keys {:a {:b 1 :e 3} :c {:d 2}}) => {[:a :b] 1 [:a :e] 3 [:c :d] 2}
(flatten-keys {:a {:z nil :b 1 :e {:f 4 :g 5}}}) => {[:a :z] nil [:a :b] 1 [:a :e :f] 4 [:a :e :g] 5}
; update-values applies a function (and any additional args) to
; each value in a map.
(update-values {:b {:c :d :e :f} :h {:c :d :e :f}} dissoc :c) => {:b {:e :f} :h {:e :f}}
; update-keys applies a function (and any additional args) to
; each key in a map.
(update-keys {1 :a 2 :b} + 1) => {2 :a 3 :b}
; nth-values returns all values at or below a key depth
(nth-vals 2 {1 {2 3} 4 {5 6}}) => [3 6]
(nth-vals 2 {:a :a 1 {2 3} 4 {5 {6 7}}}) => [3 {6 7} :a]
; key-by keys a new map from an xrel by applying a fn to each
; element of an xrel
(key-by :a [{:a 1 :b 1} {:a 2 :b 2} {:a 3 :b 3}]) => {1 {:a 1 :b 1} 2 {:a 2 :b 2} 3 {:a 3 :b 3}}
; xrelify converts a map into an xrel, mapping each k/v pair to a
; k key and a v key
(xrelify {1 2 3 4} :x :y) => [{:x 1 :y 2} {:x 3 :y 4}]
; replace-values replaces the values of keys that exist in a map
; (and ignores any replacement values that have keys that do not
; exist in the original map)
(replace-values {:a 1 :b 2} {:b 3 :c 4}) => {:a 1 :b 3}
