# Ruby::ShortUrl

## Description
Ruby implementation for generating Tiny URL. The implementation is based on [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.
>
> The URL alphabet is fully customizable and may contain any number of characters.
> The intended use is that incrementing, consecutive integers will be used as keys to generate the short URLs. For example, when creating a new URL, the unique integer ID assigned by a database could be used to generate the URL by using this module. Or a simple counter may be used. As long as the same integer is not used twice, the same short URL will not be generated twice.
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
```
### Create your own URL Shortner
```rb
class CustomEncoder < Ruby::ShortUrl::Encoder
def initialize
# Set your own custom alphabet and block_size
super(alphabet: "0123abc", block_size: 5)
end
end
```
```rb
# > custom_encoder = CustomEncoder.new
# => #
#
# > custom_encoder.encode_url(1)
# => "00022"
# > custom_encoder.encode_url(2)
# => "00011"
# > custom_encoder.encode_url(3)
# => "00033"
# > custom_encoder.encode_url(4)
# => "0000a"
#
# > custom_encoder.decode_url("00022")
# => 1
# > custom_encoder.decode_url("00011")
# => 2
# > custom_encoder.decode_url("00033")
# => 3
# > custom_encoder.decode_url("0000a")
# => 4
```
