->intclj/s
(->int value)Coerce a given value as integer. If the value is not a number, returns nil.
Coerce a given `value` as integer. If the `value` is not a number, returns `nil`.
->uuidclj/s
(->uuid value)Coerce a given value as java.util.UUID. When the value is not a valid UUID, it returns nil.
In ClojureScript there is not UUID class/function (not even in Google Closure Library). Thus in ClojureScript
it returns just string value for non-blank value.
Coerce a given `value` as `java.util.UUID`. When the `value` is not a valid UUID, it returns `nil`. In ClojureScript there is not UUID class/function (not even in Google Closure Library). Thus in ClojureScript it returns just `string` value for non-blank `value`.
case+clj/smacro
(case+ e & clauses)Same as case, but evaluates dispatch values, needed for referring to class and defined constants as well as java.util.Enum instances.

if-let*clj/smacro
(if-let* bindings then)(if-let* bindings then else)Taken from https://clojuredocs.org/clojure.core/if-let. It's if-let with multiple bindings. It allows to flatten and simplify some code nesting, for instance: From (if-let [some-x (x)] (if-let [some-y (y)] (if-let [some-z (z)] :found :not-found) :not-found) :not-found) into (if-let* [some-x (x) some-y (y) some-z (z)] :found :not-found)
It doesn't work in ClojureScript.

Lower cases first character of a given value. It's safe, when the value is nil or empty string returns nil,
otherwise string.
Lower cases first character of a given `value`. It's safe, when the `value` is `nil` or empty `string` returns `nil`, otherwise `string.`
non-blankclj/s
(non-blank input)Return a given input when it isn't nil. Otherwise nil is returned. It's useful for some-> macros.
Return a given `input` when it isn't `nil`. Otherwise `nil` is returned. It's useful for `some->` macros.
update-keysclj/s
(update-keys f m)(update-keys f x m)(update-keys f x y m)(update-keys f x y z m)(update-keys f x y z more m)Applies a given function f on every key in a given associative structure m, where f is a function
that will take a key-name and any supplied args and return new value.
Applies a given function `f` on every key in a given associative structure `m`, where `f` is a function that will take a key-name and any supplied args and return new value.
update-valsclj/s
(update-vals f coll)Applies a given function f on every value in a given coll.
Applies a given function `f` on every value in a given `coll`.
upperfclj/s
Upper cases first character of a given value. It's safe, when the value is nil or empty string returns nil,
otherwise string.
Upper cases first character of a given `value`. It's safe, when the `value` is `nil` or empty `string` returns `nil`, otherwise `string.`
