module BBS::Selector::Cells

What a Selector shows, as segments: [text, colour, reversed], the colour a role of Selector::COLORS or an item’s own. The layout (Columns or Row) asks for the cells; the painter (the Selector on an ANSI line, a BBS::Petscii::CanvasMenu on a canvas) draws them.

def across_cells
  fitting = fitting_items
  pad = @width - fitting.sum { |item, _| word(item).length + 2 }
  fitting.flat_map { |item, i| across_cell(item, i) } << [' ' * pad, :text]
end

The items on one row as segments, each a key letter and its label, the lit one a bar; the items that do not fit are left off.

def cell(index, width)
  item = @items[index]
  return [[' ' * width, :text]] unless item
  return [[label(" #{item.label}", width), :heading]] if item.heading

  item_cell(item, index, width)
end

Item index as a cell width wide, a list of segments (see #paint): blank past the last item, a heading in its colour, the lit one as a bar of plain text, the others as a key and a label.
