Instance Method Details

#add_closing(position, text) ⇒ Object

Adds stuff to the weaver.

See add_opening

For closing-tags.

def add_closing(position, text)
  check_position(position)
  @insert_positions << TextWeaver::InsertPosition.new(position, @set * -1, text)
end

#add_opening(position, text) ⇒ Object

Adds stuff to the weaver.

This makes sure that different kinds of tags are kept together (opening and closing-tags in order. If are set 1, and set 2, then overlapping ‘s and ’s are kept in order, so <b>the <i>cow, instead of the cow).

For opening-tags.

def add_opening(position, text)
  check_position(position)
  @insert_positions << TextWeaver::InsertPosition.new(position, @set, text)
end

#next_set ⇒ Object

Increases the set-counter…

(the thing that keeps tag-types apart)

def next_set
  @set += 1

#weave ⇒ Object

(self.text remains unmodified)
