SetClass

Set as a class NOT as a struct enabling inheritance with a fixed type etc

ideally this will be an EXACT duplicate of the stdlib Set struct, but as a class (and with a name change) tests should all run as per the original (with obvious changes), and this should be maintained in parallel with the stdlib version ... why does this exist ... why does anything exist?

Installation

Add this to your application's shard.yml:

dependencies:
  SetC:
    github: johnjansen/SetClass

Usage

require "SetC"

class DictionaryOfWords < SetC(String)
  getter :max_word_size
  @max_word_size : Int32 = 0
  
  def add(other : String)
    @max_word_size = other.size if other.size > @max_word_size
    super
  end
end

d = DictionaryOfWords.new
d << "word"
d.max_word_size #=> 4
