clj-toolbox.prelude — org.clojars.tanelso2/clj-toolbox 2.0.0

Functions that should be in clojure.core (or just functions I use very frequently)

any-in? clj

Returns true if (pred x) is logical true for any x in coll, else false.

Copied from clj-toolbox.colls/any-in?

box-trim clj

Copied from clj-toolbox.strings/box-trim

derefable? clj

Returns true if x is an instance of clojure.langIDeref

Copied from clj-toolbox.derefs/derefable?

find-first clj

Returns the first x in coll for which (pred x) returns true. returns nil if none is found

Copied from clj-toolbox.colls/find-first

into-map clj

Transforms coll into a hash-map by using (kf x) as the key and (vf x) as the value for each x in coll vf defaults to identity if not provided if only coll is provided, will assume coll is a list of pairs

Copied from clj-toolbox.colls/into-map

not-empty? clj

Returns true if x is not empty, else false.

Exists because doing (not (empty? x)) is inefficient

Copied from clj-toolbox.colls/not-empty?

now clj

Gets the time in milliseconds since unix epoch as a Long

Copied from clj-toolbox.timetools/now

parse-int clj

Shortcut for Integer/parseInt to make it easier to pass around as an argument

Copied from clj-toolbox.maths/parse-int

re-has? clj

Tests whether re matches any part of s. Returns a boolean

Copied from clj-toolbox.strings/re-has?

split-whitespace clj

Copied from clj-toolbox.strings/split-whitespace

square clj

Returns the square of a number

Copied from clj-toolbox.maths/square

strict-partition clj

Like parition, but throws an exception if the number of elements in coll are not evenly divisible by n, instead of partition's behavior of having the last group be too small.

Copied from clj-toolbox.colls/strict-partition

sum clj

Gets the sum of every element in coll

Copied from clj-toolbox.maths/sum

sum-by clj

Gets the sum of (f x) for every x in coll

Copied from clj-toolbox.maths/sum-by

take-range clj

Returns the part of the coll from index start (inclusive) to end (exclusive).

Copied from clj-toolbox.colls/take-range

unlazy clj

Unwraps x if it is a clojure.lang.IDeref. Otherwise just returns x

Copied from clj-toolbox.derefs/unlazy

update! clj

Like update, but for transients

Copied from clj-toolbox.transients/update!
