Re: Ruby Quiz is Back - Challenge #1 - Read Comma-Separated Values (CSV) from the "Real World"

Hello,
   sorry for the "minified" code snippet version for the Ruby Quiz #1.
Trying again (looks good in the email preview):

---
class CSV
  include Mealy

  initial_state(:start) { @line = []; @text = '' }

  read(state: :start, on: "\n")

  transition(from: :start, to: :comment, on: '#')
  transition(from: :comment, to: :start, on: "\n")
  read(state: :comment)


  transition from: [:normal, :start], to: :quote, on: '"'
  transition from: :quote, to: :normal, on: '"'

  transition(from: :start, to: :normal, on: ',') { @line << '' }
  transition(from: :start, to: :normal, on: ' ')
  transition(from: :start, to: :normal) { |c| @text << c }
  transition(from: :normal, to: :start, on: "\n") do
    emit @line << @text; @line = []; @text = ''
  end

  read state: :normal, on: ' '
  read(state: :normal, on: ',') {  @line << @text; @text = '' }

  read(state: [ :normal, :quote ]) { |c| @text << c }

  finish { emit @line unless @line.empty? }
end

def parse(text)
  CSV.new.run(text.chars).entries
end

  Happy hacking and data wrangling with Ruby.
