        * 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>

        * HTML.pm.src: Remove checking for control character, surrogate
        pair, or noncharacter code points and non-Unicode code
        points (they should be handled by Whatpm::Charset::UnicodeChecker).

        character stream error handlers.

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

        as a hash.

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

        * HTML.pm.src: Regexp typo fixed.  |{prev_char}|
        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

        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>

        * HTML.pm.src: Check points added to newly added branches.

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

        Remove |{entity_in_attr}| and |{last_attribute_value_state}|
        and replaced by |{prev_state}|.

        * mkhtmlparser.pl: Remove |{char}| feature.
        Remove |!!!back-next-input-character;| macro.

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

        * HTML.pm.src: Finally we get rid of all the inner loops.  Remove
        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.

        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
        for |set_inner_html| for |Element|s).

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

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
        |chardecode:fallback| error, since it is not the encoding
        being used alternatively.

2008-09-06  Wakaba  <wakaba@suika.fam.cx>

        * HTML.pm.src: Support for |XSLT-compat| (HTML5 revision 2141).

        * HTML.pm.src: Bug fix and sync with the spec with regard
        to after after frameset insertion mode processing (HTML5

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 "/.."

        * WebIDL.pm ($get_scoped_name): Append "::::" if the last
        terminal of the ScopedName is "DOMString", such that whether
        the last part of the scoped name is "DOMString" or "_DOMString"
        later.  It is necessary to determine whether a |typedef|
        definition should be ignored or not.
        (parse_char_string): Unescape the identifier of
        exception members.
        ($resolve): Return undef for builtin types and sequence<T>

        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).
        ($get_next_token): The second item in the array that represents
        a integer or float token is now a Perl number value, not the
        original string representation of the number.
        (check): Support for const value consistency checking.
        No extended attribute is defined for constants.
        (Node subclasses): Use simple strings rather than array references
        for default data type values.
        ($serialize_type): Type values are now simple strings.
        (value): If the new attribute value is a false value, then
        a FALSE value is set to the attribute.

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

        * WebIDL.pm ($get_scoped_name): Now scoped names are stored
        in its stringified format ("scoped name" as defined in the
        spec).  Note that future version of this module should not use
        array references for type values and the |type_text| attribute
        should be made obsolete.
        (parse_char_string): Unescape attribute names.
        (check): Support for checking of whether inherited interfaces
        are actually defined or not.  Support for checking of whether
        interface member identifiers are duplicated or not.
        ($serialize_type): Scoped names are returned as is.  A future
        version of this code should escape identifiers other than "DOMString",
        otherwise the idl_text would be non-conforming.

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

        * WebIDL.pm (parse_char_string): Set line/column numbers
        to generated nodes.  Unescape identifiers.  Extended attributes

        not prepended to the returned text.

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

        * WebIDL.pm (parse_char_string): Set line/column numbers
        to interface object experimentally.  s/shift/pop/g, shift
        would make things wrong.  Support for interface forward
        declarations was missing.  Broken interface declarations
        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.
