clj-left-pad

A Clojure library for left-padding strings, with a function signature that lends itself better to functional style programming.

Usage

In your project.clj:

  :dependencies [[org.clojure/clojure "1.8.0"]
                 [clj-left-pad "1.0.0"]])

And in the file you want to use clj-left-pad:

(ns your-beautiful-thing.core
  (:require [clj-left-pad.core :refer [left-pad]))

(left-pad 5 "foo")
;=> "  foo"

(left-pad "x" 5 "foo")
;=> "xxfoo"

Motivation

There are, at this time of writing (2018-02-11), three libraries for left-padding strings on clojars, and all of them have the same function signature:

(left-pad :stringToPad :length :paddingCharacter)

They all otherwise do the same, some utilizing other libraries for string formatting and such. I got a bit annoyed, having to monkey-patch an imported library to have the signature I wanted

(defn proper-left-pad
  ([len s] (left-pad s len))
  ([ch len s] (left-pad s len ch)))

So I wrote my own. No, I hope you do not seriously need to ever use this little library.
