Functional programming utility functions

ajuxt clj

(ajuxt f)

(ajuxt f g)

(ajuxt f g h)

(ajuxt f g h & fs)

Like juxt combined with apply. Takes a set of functions, and returns a function of the same arity as the number of functions that will call each function with the arg that matches it positionally, and return a vector of the results.

((ajuxt a b) x y) => [(a x) (b y)]

cond-let clj macro

(cond-let & clauses)

Like cond, but each test should be in the form of [binding test]. If test evaluates logical true, then the associated binding will be available in the corresponding expression.

cond-let-> clj macro

(cond-let-> expr & clauses)

Like cond->, but each test should be in the form of [binding test]. If test evaluates logical true, then the associated binding will be available in the corresponding expression.

cond-let->> clj macro

(cond-let->> expr & clauses)

Like cond->>, but each test should be in the form of [binding test]. If test evaluates logical true, then the associated binding will be available in the corresponding expression.

cond-let-some-> clj macro

(cond-let-some-> expr & clauses)

Like cond-let->, but accepts false values in tests

get-in* clj macro

(get-in* m ks)

Faster version of get-in as a macro. Does not support default value.

get-value clj

(get-value m key-or-path)

(get-value m key-or-path default)

Calls get, or get-in if key-or-path is a vector. Optional default.

pred-pattern clj

(pred-pattern p1)

(pred-pattern p1 p2)

(pred-pattern p1 p2 p3)

(pred-pattern p1 p2 p3 & ps)

Takes variable number of preds, and returns a function that takes a collection and returns true if each of the preds matches the position in the collection. Eg:

((pred-pattern even? odd? nil?) [1 3 nil :ignored :ignored]) ;; => true
