Re: Parsing a list

[Bastien DUMONT <bastien.dumont-VwIFZPTo/vqsTnJN9+BGXg@public.gmane.org>]

Doesn't items.listAttributes.start, items.listAttributes.style and items.listAttributes.delimiter yield what you are looking for?

By the way, you can replace `if nil ~= item` with `if item`: in Lua, a nil value evaluates to false and any non-nil and non-false value evaluates to true.
