	the spec.

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

	character stream error handlers.

2008-09-15  Wakaba  <wakaba@suika.fam.cx>

	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.

	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>

	* HTML.pm.src: Make |PUBLIC| and |SYSTEM| keyword tokenizing
	into their own tokenizer states.

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
	into four states so that no longer does the tokenizer have to push
	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

2008-09-10  Wakaba  <wakaba@suika.fam.cx>

	* HTML.pm.src: Ignore punctuations in charset names.

2008-09-10  Wakaba  <wakaba@suika.fam.cx>

	* ContentChecker.pm: Support for charset-layer error levels.

	* HTML.pm.src: Don't specify |text| argument for the

	per the old spec before the r1909 changes.

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

	* HTMLTable.pm: scope=auto algorithm fix synced with the

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

	* HTMLTable.pm: Zs is not what we want; we want White_Space! (HTML5
	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
	revision 2123).  Empty unquoted attribute values are no

	* 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
	formats are rarely added.  Path segments starting with "/.."
	were misinterpreted as a dot-segment.

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

	* URIChecker.pm (check_iri_reference): Requires

	hexadecimal numbers (the original pattern, taken from the spec,

	it does not match with remaining "x..." part of a "0x..." integer
	literal.

	are actually defined or not.  Support for checking of whether

	before the |{| character.
	(Interface idl_text): Support for interface forward declarations.
