module Lucky::AllowedInTags

Overview

Include this module in a type to allow it to be output in tags

Lucky already includes this in a few common types like Int and Bool. Typically this is enough but if you have a type you want to allow in tags, you can do so.

For example:

class EmailAddress
  include Lucky::AllowedInTags

  def initialize(@value : String)
  end

  def to_s(io)
    io.puts @value
  end
end

Now an EmailAddress can be used for tag content without calling to_s:

h1 EmailAddress.new("myemail.com")

Direct including types

• Bool
• Int16
• Int32
• Int64
• UUID
