end

def fold_first

Returns nothing

Internal: Fold the adjacent paragraph block into the list item text 
def fold_first
  @text = @text.nil_or_empty? ? @blocks.shift.source : %(#{@text}#{LF}#{@blocks.shift.source})
  nil
end

def initialize parent, text = nil

text - the String text (default nil)
parent - The parent list block for this list item

Public: Initialize an Asciidoctor::ListItem object. 
def initialize parent, text = nil
  super parent, :list_item
  @text = text
  @level = parent.level
  @subs = NORMAL_SUBS.drop 0
end

def simple?

Return true if the list item contains no blocks or it contains a single outline list. Otherwise, return false.

Primarily relevant for outline lists.
Check whether this list item has simple content (no nested blocks aside from a single outline list).

  @blocks.empty? || (@blocks.size == 1 && List === (blk = @blocks[0]) && blk.outline?)
end
