Functional programming utility functions
Functional programming utility functions
(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 & 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-> expr & clauses)Like cond-let->, but accepts false values in tests
Like cond-let->, but accepts false values in tests
(get-in* m ks)Faster version of get-in as a macro. Does not support default value.
Faster version of get-in as a macro. Does not support default value.
(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.
Calls `get`, or `get-in` if key-or-path is a vector. Optional default.
(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
