Question

I\'m trying to pick a random element from an array -- is this possible using Liquid/Jekyll?

I can create an array -- and access a given index ... but is there a way to \

You can create a plugin to get a random element. Something like this:

module Jekyll
  module RandomFilter
    # Use sample to get a random value from an array
    #
    # input - The Array to sample.
    #
    # Examples
    #
    #   random([1, 2, 3, 4, 5])
    #   # => ([2])
    #
    # Returns a randomly-selected item out of an array.
    def random(input)
      input.sample(1)
    end
  end
end

Liquid::Template.register_filter(Jekyll::RandomFilter)

Then do something like this in your template to implement:

{% assign myArray = '1|2|3|4|5 | split: '|' %}
{% assign myNumber = myArray | random %}
