def beginning(word)
  # That weird looking thing below is interpolated as an array, so it would
  # come out looking like: [a, e, i, o ,u]
  %w(a e i o u).include?(word[0]) ? 'an' : 'a'
end

#build_table_rows ⇒ Object

Pulled this and the functions it calls below out here to make it a little clearer and to be able to make changes without breaking my brain.

#hud_table ⇒ Object

Lays out the top of the screen in a nice way for me. It would be great if I could get the whole game to display in a bordered table, but alas, the gem I’m using can’t do it, and I appear to lack the technichal knowhow.

  table.style = { width: 80, padding_left: 3, border_x: '=' }
  table.rows = build_table_rows
  system 'clear'
  puts table
  puts room_description
end

#room_description ⇒ Object

Pretty straightforward but I have plans for the room description generation to be far more interesting. So check back here sometime in the next millenium.
