Overview

The main DSL, every single call to the “label” method pushes the parameters to an array and “raw” method then joins the array to generate the actual string to be used in PS1 or wherever.

ie. canvas = Canvas.new

canvas.label "\\[\\033[33m\\]user:" => yellow text
canvas.label "\\[\\033[34m\\]host" => blue text
canvas.show => \\[\\033[33m\\]user:\\[\\033[34m\\]host => user:host
