Clojure library of sundry utility functions and macros
via Clojars:
[waffletower/serum "0.10.0"]
Compare to: https://github.com/egamble/let-else
The and-let macro is quite similar to the Scheme and-let* special
form. Being honest about my own developer history, I wanted
short-circuiting behavior for bindings in Clojure somewhat analagous
to optional chaining
(https://en.wikipedia.org/wiki/Safe_navigation_operator) in
object-oriented languages like Swift and Objective-C. Unlike
and-let* in Scheme, I also wanted to support else conditions. Evan
Gamble's richly featured let-else provides the facility for else
handling for each individual binding. I wanted a simple blanket
else behavior instead.
(and-let [a (its)
b (not*)
c (my)
d (disco)]
(fire-dj)
(dance))Evaluation of bindings stops should a binding evaluate
falsey. In the above example, (my) and (disco) will not be
evaluated when (not*) evaluates falsey.
The shift function is similar to clojure.core/partial. shift
accepts a function f and returns a function of one argument mapped
to the first argument of the function f:
(map (comp (shift select-keys [:name :hat :shoe-size])
(partial filter friend?) my-people)clj -Atest
