# Ruby::ShortUrl

Ruby implementation for generating Tiny URL. Ruby implementation of [python-short_url](https://github.com/Alir3z4/python-short_url)

> A bit-shuffling approach is used to avoid generating consecutive, predictable URLs. However, the algorithm is deterministic and will guarantee that no collisions will occur.

More detail is [here](https://github.com/Alir3z4/python-short_url#short-url-generator).

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'ruby-short_url'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install ruby-short_url

## Usage

```rb
# shorten id
Ruby::ShortUrl::Encoder.new.encode_url(123456) # => "00crI"

# decode encoded
Ruby::ShortUrl::Encoder.new.decode_url("00crI") # => 123456
```
