Granite::Validators

Analyze validation blocks and procs

By example:

validate :name, "can't be blank" do |user|
  !user.name.to_s.blank?
end

validate :name, "can't be blank", ->(user : User) do
  !user.name.to_s.blank?
end

name_required = ->(model : Granite::Base) { !model.name.to_s.blank? }
validate :name, "can't be blank", name_required
