	* ContentChecker.pm, HTMLTable.pm: U+000B is no longer part of
	space characters (HTML5 revision 1738).

2008-09-20  Wakaba  <wakaba@suika.fam.cx>

	* HTML.pm.src: The "anything else" case for the "after after body"
	insertion mode was not updated to swtich to the "in body"
	insertion mode.  U+000B is no longer a space character for the
	purpose of tree construction phase (HTML5 revision 1738).

2008-09-20  Wakaba  <wakaba@suika.fam.cx>

	* HTML.pm.src: U+000B is no longer a space character (HTML5

2008-09-20  Wakaba  <wakaba@suika.fam.cx>

	* ContentChecker.pm ($IsInHTMLInteractiveContent): New.

2008-09-18  Wakaba  <wakaba@suika.fam.cx>

	commented out.

2008-09-16  Wakaba  <wakaba@suika.fam.cx>

	* WebIDL.pm: Support for the reminding extended attributes are
	added.  It does not satisfy the definition that a forward
	interface declaration has an extended attribute.  It seems that
	unless explicitly allowed multiple extended attributes with the
	same name is not allowed, though it is not explicitly mentioned in
	the spec.

2008-09-16  Wakaba  <wakaba@suika.fam.cx>

	* WebIDL.pm: Unescapes extended attribute names and extended

	and |{next_char}| initializations are moved to initialization
	method.  |{read_until}| now supports buffering.  Sync |set_inner_html|
	with |parse_char_stream|.

2008-09-14  Wakaba  <wakaba@suika.fam.cx>

	* HTML.pm.src (parse_char_stream): Make |set_next_char|
	invoke |manakai_read_until|, not only |read|, where
	possible, to decrease the number of |read| method calls.

	* mkhtmlparser.pl: Related changes to the aforementioned
	modification.

2008-09-14  Wakaba  <wakaba@suika.fam.cx>

	* HTML.pm.src: Use |read| instead of |getc|.  |set_inner_html|
	would report character error from now.

2008-09-14  Wakaba  <wakaba@suika.fam.cx>

	* HTML.pm.src: White-space-leaded non-white-space character
	tokens in "before head insertion mode" was not
	correctly handled.
	(set_inner_html): Reimplemented using CharString decodehandle
	class.  Support for $get_wrapper argument.  Support
	for |{read_until}| feature.

2008-09-14  Wakaba  <wakaba@suika.fam.cx>

	* HTML.pm.src: Make a "bare ero" error for unknown
	entities point the "&" character.

2008-09-14  Wakaba  <wakaba@suika.fam.cx>

	be added to the list of excluded characters.

2008-09-14  Wakaba  <wakaba@suika.fam.cx>

	* HTML.pm.src ($char_onerror): Have character decoder's |line|
	and |column| a higher priority than the one set by the
	tokenizer's input handler.
	($self->{read_until}): Exclude U+FFFD (but this might
	not be necessary, since now we do line/column fixup in
	the character decode handle).

2008-09-14  Wakaba  <wakaba@suika.fam.cx>

	* HTML.pm.src: Use |{read_until}| where possible.

2008-09-14  Wakaba  <wakaba@suika.fam.cx>

	* HTML.pm.src: Change |{getc_until}| to |{read_until}|
	and |manakai_getc_until| to |manakai_read_until| to
	reduce the number of string copies.

2008-09-14  Wakaba  <wakaba@suika.fam.cx>

	* HTML.pm.src (parse_char_string): Use newly created
	|Whatpm::Charset::DecodeHandle::CharString| instead of Perl's
	standard feature to |open| a string as a filehandle,
	since Perl's string filehandle seems not supporting |ungetc|
	method correctly.
	(parse_char_stream): Define |{getc_until}| method.
	(DATA_STATE): Experimental support for |getc_until| feature.

2008-09-13  Wakaba  <wakaba@suika.fam.cx>

	Remove |!!!back-next-input-character;| macro.

2008-09-13  Wakaba  <wakaba@suika.fam.cx>

	entity related tokenizer states in favor of new states
	implementing the consume character reference algorithm.

2008-09-13  Wakaba  <wakaba@suika.fam.cx>

	* HTML.pm.src: "Consume a character reference" algorithm is
	now implemented as a tokenizer's state, rather than
	a method, with minimum changes (more changes will
	be made, in due course).  "Bogus comment state"'s inner
	loop gets removed.

2008-09-13  Wakaba  <wakaba@suika.fam.cx>

	is split into three states.

2008-09-13  Wakaba  <wakaba@suika.fam.cx>

	* HTML.pm.src: |CLOSE_TAG_OPEN_STATE| is broken into
	itself and new |CDATA_PCDATA_CLOSE_TAG_STATE| so that
	no longer does the tokenizer have to push back next input
	characters in those states.

2008-09-13  Wakaba  <wakaba@suika.fam.cx>

	* HTML.pm.src: |MARKUP_DECLARATION_OPEN_STATE| broken

	back next input characters in that state.

2008-09-11  Wakaba  <wakaba@suika.fam.cx>

	* HTML.pm.src: Methods now accept additional parameter, $get_wrapper,
	which can be used to insert some wrapper between the character
	stream handle and the tokenizer.  (It is currently not supported

	revision 2094).

2008-08-30  Wakaba  <wakaba@suika.fam.cx>

	* ContentType.pm: Support for image/svg+xml (HTML5 revision 2096).

2008-08-30  Wakaba  <wakaba@suika.fam.cx>

	* HTML.pm.src: '"' and "'" at the end of attribute
	name (after another attribute) now raise parse error (HTML5

	* ContentChecker.pm: Error level definition for |xml_id_error|
	was missing.

	* URIChecker.pm: The end of the URL should be marked as the
	error location for an empty path error.  The position
	between the userinfo and the port components should be
	marked as the error location for an empty host error.

2008-08-30  Wakaba  <wakaba@suika.fam.cx>

	* URIChecker.pm: Set parameters representing where in the
	value the error occurs for errors.  Report unknown
	address format error in warning level, since address

	code.

2008-08-02  Wakaba  <wakaba@suika.fam.cx>

	* WebIDL.pm ($integer): Order of selections are changed to match
	hexadecimal numbers (the original pattern, taken from the spec,
	was not work for hexadecimal numbers, because the "0" prefix
	matches to the [0-7]* part (as an empty string) and therefore
	it does not match with remaining "x..." part of a "0x..." integer
	literal.
	($get_type): It now returns a string, not an array reference,
	for regular types and |sequence| types (i.e. it in any case
	returns a string).

	array references for type values and the |type_text| attribute
	should be made obsolete.
	(parse_char_string): Unescape attribute names.
	(check): Support for checking of whether inherited interfaces
	are actually defined or not.  Support for checking of whether
	interface member identifiers are duplicated or not.

	with no block were not ignored entirely.
	(Whatpm::WebIDL::Node): New abstract class.  This class
	makes things easier.
	(child_nodes): New attribute.  Unlike DOM's attribute with
	same name, this attribute returns a dead list of nodes for
	simplicity.
	(get_user_data, set_user_data): New methods.
	(Module idl_text): A SPACE character should be inserted
	before the |{| character.
	(Interface idl_text): Support for interface forward declarations.
