-- This module outputs different kinds of lists. At the moment, bulleted, -- unbulleted, horizontal, ordered, and horizontal ordered lists are supported.

-- Indent for horizontal lists if listType == 'horizontal' or listType == 'horizontal_ordered' then local indent = tonumber(args.indent) indent = indent and indent * 1.6 or 0 if indent > 0 then data.marginLeft = indent .. 'em' end end

-- List style types for ordered lists -- This could be "1, 2, 3", "a, b, c", or a number of others. The list style -- type is either set by the "type" attribute or the "list-style-type" CSS -- property. if listType == 'ordered' or listType == 'horizontal_ordered' then data.listStyleType = args.list_style_type or args['list-style-type'] data.type = args['type']

-- List style -- ul_style and ol_style are included for backwards compatibility. No -- distinction is made for ordered or unordered lists. data.listStyle = args.list_style
