A few helpful functions for terminal I/O. Read more in the readme.

• step should be used to show a group of actions is about to start
• action should be used to show an action is starting
• info should be used to show any important information from an action
• done should be used to show a group of steps is done

Steps and actions can take blocks:

Tio.step "Rethreading flux capacitor" do
  Tio.action "Initializing agitator" do
    Tio.info("3... 2... 1...")
  end

  Tio.action "Regulating coherence" do
    Tio.info("0.5... 0.75... 1.0")
  end
end
Tio.done()

Messages can be iodata (strings, lists, or improper lists) and are ultimately formatted with IO.ANSI.format/2. One addition is that if a message is a list, then a {:quoted, message} tuple will be formatted in the quote color:

Tio.info(["File ", {:quoted, "foo.txt"}, " has ", {:quoted, "20"}, " lines"])
