Embedding code blocks in Leanpub aside/warning/tip blocks

gistfile1.txt

Example using both an embedded code block (with language explicitly specified), and inline code.

T> When a Ruby object is printed or otherwise asked to represent itself as a
string, the `to_s` ('to string') method of that object is called. So for our
managed object what we want to do is define a `to_s` method which displays our
task attributes. Add this method to `app/task.rb`:
T>
{lang="ruby"}
    def to_s
      "Priority: #{self.priority} " +
      "Completed: #{self.completed} " +
      "Description: '#{self.task_description}'"
    end
T>
T> `Task` records will be shown in the console in a more informative form:
T>
T> `=> [Priority: 5 Completed: 0 Description: 'Go to the supermarket']`
