CrISBN - Crystal ISBN Library

CrISBN - Crystal library to handle ISBNs. The goal is for this library to handle any action you'd want from an ISBN such as validate, generate new ones, check to see if an ISBN belongs to something and what, and other actions that come to mind.

This project came about when I was toying with the idea of a tool that can generate a random ISBN then search that book for you display a new book to checkout, and since there wasn't one I created it in the language I was familiar with. From that I decided to create a tool-set that allows me to not just generate ISBNs but check other ISBNs, validate them, search for them, etc.

Installation

  • Recommended: if you want to use cake, which is make for crystal then, (this is recommended )
    • Make sure you have cake installed curl https://raw.githubusercontent.com/axvm/cake/master/install.sh | bash
    • Run cake build
    • Run ./bin/crisbn
  • if you want to use make run make build

Usage

Add it to your shard.yml:

dependencies:
  crisbn:
    github: MaterialFuture/crisbn

and then install the library into your project:

$ shards install

If you want to use this in your project just reference is with

ISBN::Generate.english # => "1829404728394"

I also have a lottery-like class that is used that could be used elsewhere, right now it's accessed like

RandNum.fromZero # => 0-9

or

RandNum.fromOne # => 1-9

You can also validate an ISBN by using like below

ISBN::Generate.english(ISBN)

For more examples look in examples/ directory.
