Constructors

• .new(r : IO, **opts)

Instance Method Summary

• #acknowledge_self_closing_tag

  Section 12.2.5

• #add_child(n : Node)

  add_child adds a child node n to the top element, and pushes n onto the stack of open elements if it is an element node.

• #add_element

  add_element adds a child element based on the current token.

• #add_formatting_element

  Section 12.2.4.3

• #add_text(text : String)

  add_text adds text to the preceding node if it is a Text Node, or else it calls add_child with a new Text Node

• #adjusted_current_node

  Section 12.2.4.2

• #clear_active_formatting_elements

  Section 12.2.4.3.

• #clear_stack_to_context(s : Scope)

  clear_stack_to_context pops elements off the stack of open elements until a scope-defined element is found.

• #doc : Node

  doc is the document root element

• #element_in_scope(s : Scope, *match_tags)

  element_in_scope is like pop_until, except that it doesn't modify the stack of open elements

• #foster_parent(n : Node)

  foster_parent adds a child node according to the foster parenting rules.

• #fragment : Bool

  fragment is whether the parser is parsing an HTML fragment.

• #generate_implied_end_tags(*exceptions)

  generate_implied_end_tags pops nodes off the stack of open elements as long as the top node has a tag name of dd, dt, li, optgroup, option, p, rb, rp, rt or rtc.

• #has_self_closing_token : Bool

  Self-closing tags like

  ---

  are treated as start tags, except that has_self_closing_token is set while they are being processed

• #has_self_closing_token=(has_self_closing_token : Bool)

  Self-closing tags like

  ---

  are treated as start tags, except that has_self_closing_token is set while they are being processed

• #in_body_end_tag_formatting(atom : Atom::Atom, tag_name : String)

  TODO this is a fairly literal line-by-line translation of that algorithm.

• #in_body_end_tag_other(atom : Atom::Atom, tag_name : String)

  performs the "any other end tag" algorithm for in_body_im.

• #in_foreign_content

  Section 12.2.6

• #index_of_element_in_scope(s, *match_tags)

  index_of_element_in_scope returns the index of in @oe of the highest element whose tag is in match_tags that is in scope.

• #oe=(arr : Array(Node))
• #parse
• #parse_current_token

  runs the current token through the parsing routines until it is consumed.

• #parse_generic_raw_text_elements

  parse_generic_raw_text_elements implements the generic raw text element parsing algorithm defined in 12.2.6.2.

• #parse_implied_token(t : TokenType, atom : Atom::Atom, data : String)

  parses a token as thoug it had appeared in the parser's input

• #pop_until(s : Scope, *match_tags : Atom::Atom)

  pop_until pops the stack of open elements at the highest element whose tag is in matchTags, provided there is no higher element in the scope's stop tags (as defined in section 12.2.4.2).

• #reconstruct_active_formatting_elements

  Section 12.2.4.3.

• #reset_insertion_mode

  Section 12.2.4.1, "reset the insertion mode".

• #set_original_im

  set_original_im sets the insertion mode to return to after completing a text or inTableText insertion mode.

• #should_foster_parent

  should_foster_parent returns whether the next node to be added should be foster parented.

• #top : Node
