            ChangeLog for WebLint

1.014

    13-february-1996 neilb

    *    Weblint 1.014 released.

    12-february-1996 neilb

    *    The attribute checking code now allows percentage widths
    if the netscape extension is enabled. For example: WIDTH=50%
    Added a testcase, natch.

    10-february-1996 neilb

    *    The SIZE attribute is now accepted for the SELECT element.
    Added a test case to the testsuite.

    *    Added support for the SCRIPT element if the netscape extension
    is enabled.

    3-february-1996 neilb

    *    Released beta to weblint-victims.

    *    Created a file rc.new for the distribution, which is the part
    of the sample weblintrc which is new with this version.
    Suggested by Doug Grinbergs <[e-mail]>.

    *    Added support for new netscape elements: FRAMESET, FRAME and NOFRAMES.
    Added testcases for these.
    Suggested by Jens Thordarson <[e-mail]> and others.

    *    Added support for new netscape attributes:
        TARGET attribute for A, BASE, AREA, and FORM elements
        COLOR attribute for FONT element
        WRAP attribute for TEXTAREA element
    Also added an attribute format for the WRAP attribute.

    *    Changed the way netscape attributes are handled. Information about
    netscape attributes used to be in two places -- an associative
    array which holds regular expressions to check for the
    'netscape attribute' warning, and the code in the AddExtension()
    routine. Now the latter uses the former, which keeps things
    in sync internally, and makes it easier to update.

    *    Added a new warning, 'attribute-format', which is generated for
    badly formatted attribute values. For example:
        <IMG SRC="foo.gif" ALIGN=MIDLE ALT="alt text">
    will result in the warning:
        f.html(4): illegal value for ALIGN attribute of IMG (MIDLE)
    Code submitted by Axel Boldt <[e-mail]>.

    2-february-1996 neilb

    *    Added a blurb to the README and man page about certain versions of
    perl having bugs which are triggered by weblint.
    Suggested by Jeff Schave <[e-mail]>.

    *    Added a warning, 'bad-text-context', which warns if text appears
    in certain illegal contexts, such as UL, HEAD, etc.
    Added testcase to testsuite. At the moment the warning is given
    with the line number of the line which contains the start of the
    next element. For example:
        <UL>
        This is not legal
        </UL>
    This will generate a warning with the line number as the 3rd line,
    rather than the third, as you might expect. The warning is enabled
    by default.
    Suggested by Richard Finegold <[e-mail]>.

    *    Fixed the extension handling code so you can specify multiple
    extensions:
        weblint -x netscape,java foo.html
    Added a testcase for this. For this particular example, you could
    argue that java should be automatically enabled if you enable
    the netscape extension . . .
    Suggested by a number of people, several of whom supplied patches.

    *    Added the LOWSRC attribute for IMG element when the netscape
    extension is enabled. Added case to testsuite.
    Patch from David Koblas <[e-mail]>

    29-january-1996 neilb

    *    Added a new warning `heading-mismatch', which flags the common
    mistake of closing a header with a different level tag. Eg:
        <H2>Level two heading</H1>
    This used to result in two warnings: one because no closing </H2>
    was seen, and the other because </H1> was seen without a matching
    prior <H1>. You now get one warning that the heading tags are
    mismatched:
        Malformed header - open tag is <H2>, but closing is </H1>
    Modified the test case in the test suite. The warning is enabled
    by default.

1.013

    1-january-1996 neilb

    *    Changed the output format when running the testsuite to be more
    terse, so everything stays on screen. You can always look at the
    log file for greater verbosity.

    *    Added a function PickTmpdir() to the testsuite, which is used to
    determine a valid temporary working directory. Previously the
    testsuite assumed that /usr/tmp would be present, which is not true
    on all systems.
    Patch submitted by Charles F. Randall <[e-mail]>

    *    Updated the text at the head of the sample configuration file,
    weblintrc, to clarify that the enable'd warnings in the file are
    enabled by default, so you don't really have to enabled them in
    your config file, unless you like explicitness.

    *    Added entry to weblintrc for variable 'directory-index'.

    21-december-1995 neilb

    *    Changed the default for the 'url-get' variable to be undefined,
    rather than "lynx -source". This means that "weblint -todo" will
    print the URL of the todo list, unless you explicitly set the
    url-get variable.

    16-december-1995 neilb

    *    Added a warning 'literal-metacharacter', which warns about
    metacharacters included literally, where they should be represented
    using entities. Currently just warns about >. Warning is enabled by
    default. Simple testcase added to testsuite.
    Suggested by Michael P. Gerlek <[e-mail]>

    *    The variable 'directory-index' can now be set to a comma-separated
    list of filenames, if you want to allow multiple names for directory
    index files, such as welcome.html or index.html. In your .weblintrc:
        set directory-index = welcome.html, index.html
    Suggested by Eric Maryniak <[e-mail]>.

    15-december-1995 neilb

    *    Fixed a bug in the testsuite for testcases where warnings are
    expected. If you got more warnings than expected, but the extraneous
    warnings were on the same line as expected warnings, then the
    test was not marked as unsuccessful, as it should have been.

    *    Added a warning 'require-doctype', which if results in a warning if a
    page does not have a DOCTYPE as the first element. Disabled by default.
    Two cases added to testsuite. Not enabled with -pedantic.
    Suggested by Larry Virden <[e-mail]>

    *    Running "weblint -todo" will now pull down the latest todo list
    from our ftp server if you have set the 'url-get' variable.
    Otherwise it prints the URL of the webified version of the ToDo list.

    *    Reformatted the text displayed with the -help and -U switches,
    so that it will fit on a standard sized tty or PC.
    Suggested by Frank Steinke <[e-mail]>

    *    Fixed bug related to container elements where the closing tag
    is optional, such as LI. If a comment was the last thing,
    then weblint would warn that the container was empty. E.g.
        <UL>
        <LI>line 9
        <!-- line 10 -->
        <LI>line 11
        </UL>
    Added regression test case to testsuite.
    Reported by Mark Gates <[e-mail]>

    10-december-1995 neilb

    *    Added a semi-colon to a single statement in an else clause,
    which was apparently causing problems under perl 4.019.
    Frank Steinke <[e-mail]>

    *    The README was still claiming that weblint.ps was included with the
    distribution. It now gives the URL for the copy on our ftp server.

    9-december-1995 neilb

    *    Added support for the netscape extensions added in netscape 2:
        -    ENCTYPE attribute for FORM element
        -    USEMAP attribute for IMG element (client side image maps)
        -    MAP and AREA elements

    *    Removed the todo list from the weblint script. The -todo switch
    now echoes the URL for the online todo list. Maybe in the future
    weblint -todo will grab an ascii version from a web/ftp site,
    and spit it out. This will keep the todo list current.

    *    Fixed a bug where enabling the java extension would also enable
    the netscape extension.

1.012

    9-december-1995 neilb
    *    Added an EXTENSIONS section to the man page, which describes
    the supported html extensions, and how to enable them.

    6-december-1995 neilb
    *    Changed the way the symlink check works, so a single file is still
    checked if it is a symlink and you specified -l, but you get a
    warning to that effect.
    Suggested by John F. Whitehead <[e-mail]>.

    4-december-1995 neilb
    *    If you give the -l switch and an explicit list of files, weblint
    will now ignore any which are symlinks. If you give only one file,
    specify -l, and the file is a symlink, then you get a warning that
    the file is being ignored.
    Suggested by John F. Whitehead <[e-mail]>.

    3-december-1995 neilb
    *    Created a web page version of the Artistic License, which is linked
    to the weblint home page. Weblint -v also prints the URL of this page.

    *    Added support for the Java elements APPLET and PARAM,
    as an extension 'java'. For weblint to accept the java elements:
        % weblint -x java
    or the following in your .weblintrc:
        extension java
    Added a testcase for a valid applet with param, and a testcase
    which checks that PARAM appears in an APPLET.
    Suggested by Jon Thackray <[e-mail]>

    *    Changed the version string printed for the -v/-version switch,
    so the following information is printed:
         -    version of weblint
         -    copyright me
         -    weblint is covered by the artistic license, and where to get
        a copy of the license.
    Suggested by Eric de Mund <[e-mail]>

    *    Changed the way the testsuite determines the version of weblint,
    so that it will work for old and new format version string.

    10-november-1995 neilb
    *    Changed the pedantic option so that the bad link check is not
    enabled, since it needs some work ;-)

    7-november-1995 neilb

    *    Added a warning, 'container-whitespace', which flags leading and
    trailing whitespace for specific container elements, currently
    A, TITLE, H1 through H6.
    Suggested by Richard Finegold <[e-mail]>

    *    Added a -pedantic command-line switch, which turns on all warnings
    except case-sensitive checking of element tags. This can be combined
    with -e and -d to turn on or off specific warnings.

    *    Fixed bug in the testsuite where ExpectWARN() wouldn't flag a
    failure if not all the expected warnings were seen, but all the
    warnings seen were expected.

    *    Fixed the bug whereby a container element would be reported as
    empty if the last thing in the container was a valid comment.
    Reported by Craig Leres <[e-mail]> and others.

    29-july-1995 neilb

    *    We now check for the -v, -U, -help, -version, and -todo switches
    before checking for a .weblintrc and reading the warning information.
    Suggested by Richard Finegold <[e-mail]>.

    *    Added a warning `img-size' which suggests you set WIDTH and HEIGHT
    attributes on IMG elements, since this can apparently improve
    rendering time on some browsers.  Warning is disabled by default.
    Suggested by Richard Finegold <[e-mail]>

1.011

    28-july-1995 neilb

    *    Changed the Makefile so that weblint.ps is not included as part
    of the distribution.  A postscript version of the man page is
    available from a link on the weblint home page.

    26-july-1995 neilb

    *    Added a command-line switch -urlget, to specify the command which
    weblint should use to pull down a URL.

    *    Added a warning, `attribute-delimiter', which warns about use of '
    as a delimiter for attribute values, since this is not correctly
    parsed by all browsers.

    *    Weblint now understands attribute values with are quoted with '...'
    as well as "...".  Reported by Abigail <[e-mail]>

    25-july-1995 neilb

    *    Added a new warning, `netscape-attribute', which generates a
    warning if you use netscape specific attributes for a
    non netscape-specific tag.  For example:

        <BODY BGCOLOR="#fefefe">

    Previously this would generate an "unknown attribute" warning,
    but you now get a warning that this is netscape specific, and
    you should enable the netscape extension to suppress the warning.
    Suggested out by Larry W. Virden <[e-mail]>

    *    Added a weblint variable `message-style', which can be used to
    specify the style of warning message to generate

        lint    (default)    lint-style warning messages
        short    -s        short messages (no filename)
        terse    -t        format for parsing (eg by testsuite)

    So for example, in the sample weblintrc:

        set message-style = lint

    Suggested by Philip Hallstrom <[e-mail]>.

    *    Weblint will now check pages specified by URL, for example:

        weblint http://www.khoral.com/staff/neilb/weblint.html

    Weblint uses a 'url getter', which can be specified in your .weblintrc:

        # command to use to pull back URLs for checking
        set url_get = httpget -nofollow

    *    Added a general feature for setting weblint variables in
    the weblintrc.

    *    Added a warning, 'closing-attribute', which warns if you have
    attributes for a closing tag of a container.  For example:

        <H1>This is a heading<H1 ALIGN=CENTER>

    20-july-1995 neilb

    *    Added a warning, `directory-index', which checks to see if every
    directory has an index file when recursing.  By default the index
    file is expected to be called `index.html', but this can be
    over-ridden in your .weblintrc:

        directory-index home.html

    The warning is enabled by default.
    Suggested by John F. Whitehead <[e-mail]>.

    *    Added a new warning, `empty-container', which generates a warning if
    you have an empty container element.  For example:

        <TITLE></TITLE>

    Added a testsuite case for this example.  It will also catch empty
    optional container elements, such as:

        <UL>
        <LI>blah
        <LI>
        <LI>blah blah
        </UL>

    Added a test case for this as well.

    19-july-1995 neilb

    *    Added a -warnings switch, which tells weblint to list all
    supported warnings, in the following format:

        <warning-id> ([ enabled | disabled ])
            <test of warning message>

    Suggested by Tom Neff <[e-mail]>

    18-july-1995 neilb

    *    Added a warning `must-follow', which is used to check situations
    where an element must immediately follow an other.  This checks:
         -    Shouldn't have anything appearing between the HEAD and BODY
        elements.
         -    LH (list heading) must be the first element in an OL, UL,
        or DL element.
         -    OVERLAY first in a FIG
         -    HEAD immediately follow HTML
         -    BODY immediately follow /HTML
         -    /HTML immediately follow /BODY
    Added a couple'a test cases for these.

    *    Added a check for known warnings when enabling or disabling warnings.
    The check is performed for `enable' and `disable' keywords in your
    configuration file, and also for the -d and -e switches.
    Suggested by Barry Bakalor <[e-mail]>.

    *    Fixed the bug where weblint would complain about a comment
    (claiming it was not a valid comment), if it was the last thing
    in the file.


1.010

    11-july-1995 neilb

    *    Fixed a bug whereby the - option on the command-line (to specify
    that weblint should read from standard input) did not work.

1.009

    10-july-1995 neilb

    *    Some warnings started capitalized, some lower case.  Now consistently
    lower case.  Pointed out by Larry W. Virden <[e-mail]>

    9-july-1995 neilb

    *    Added a warning `repeated-attribute' which warns about an attribute
    being repeated in the same tag.  For example:
        <IMG SRC="foo.gif" SRC="bar.gif">
    Contributed by Axel Boldt <[e-mail]>.

    *    Changed the format of the data in the __DATA__ section at the
    end of weblint.  Rather than being a colon separated list,
    each field appears on a line of its own.

    8-july-1995 neilb

    *    Added a warning `physical-font' which generates warnings if
    you use any of the following physical font markup: <B>, <I>, or <TT>.
    The warning message reminds the user of possible logical markup
    to use instead.  The warning is disabled by default.
    Suggested by Chris Siebenmann <[e-mail]>)

    *    Added more explicit context checks now that optional containers
    are supported:

        Element        Appear in    Which appears in
        --------    --------------    ----------------
        TD, TH        TR        TABLE
        ITEM        ROW        ARRAY

    *    Weblint now supports elements which are optional containers:
        DD, DT, LI, P, ROW, TD, TH, TR

    *    Added an option to tell weblint to ignore symlinks when recursing
    in a directory.  From the command-line:

        % weblint -l foo/

    or in your .weblintrc:

        ignore symlinks

    Added this to the weblintrc, but commented out by default.
    Suggested by John F. Whitehead <[e-mail]>.

    *    Got rid of the -R switch: if weblint is run on a directory, then
    it will automatically recurse in the directory.  This means that
    files and directories can be mixed on the command line; they couldn't
    with previous versions of weblint.  Suggestion and code from
    Axel Boldt <[e-mail]>

    *    Added a warning `illegal-closing', for unexpected use of a closing
    tag.  For example: <IMG ...> ... </IMG>
    Bug reported by David Begley <[e-mail]>

    *    The man page didn't say that "weblint -" specifies that weblint
    should read from standard input.
    Noted by Stephen Fitzpatrick <[e-mail]>

    *    Now use newgetopt.pl rather than getopts.pl for command-line parsing,
    since it supports long command-line switches.  Added the following
    switches:

        New Switch    Same As        Function
        ----------    -------        --------------------
        -version    -v        display weblint version
        -help        -U        display usage statement

    Turns out that newgetopt.pl is case-insensitive, so -todo *replaces*
    the -T switch.

        New Switch    Replaces    Function
        ----------    -------        --------------------
        -todo        -T        display todo list
        -stderr        -E        warnings to STDERR, not STDOUT

    *    Added a warning `unclosed-comment', which flags an unterminated
    comment.  For example <!-- blah blah > is not a legal comment.
    Previously weblint would hit this and suck in the rest of the file,
    and then warn that it hadn't seen </BODY>, </HTML> etc.
    Added test case to testsuite.
    Reported by Laurent Demailly <[e-mail]>

    *    Changed &whine() to take the line number as the first argument,
    rather than just assuming $. is the correct line number.  This
    means that warnings can be given for the right line, with a little
    work.


1.008

    4-july-1995 neilb

    *    Rewrote the man page with some custom macros to facilitate
    generation of HTML version of the man page.

    *    Fixed a number of typos in the ChangeLog, weblintrc.
    Added the "extension netscape" command to the weblintrc, commented
    out by default.  Barry Bakalor <[e-mail]>.

    *    Changed the version of tar used to create the distribution, since
    some people were having problems extracting from the archive.
    Thanks to Barry Bakalor and Anthony Thyssen for helping with this.

    2-july-1995 neilb

    *   Added CONTRIBUTIONS section at the end of the man page, listing
    everyone who has contributed something to weblint.

    *   Weblint now exits with an exit status of 1 if any warnings were
    given.  Suggestion and code from John Labovitz <[e-mail]>.

    *   Fixed bug where weblint wouldn't complain about nested FORM
    elements.  Added test case to testsuite.

    *    Fixed bug where the following MATH elements were not recognized:
        ITEM element, used within the ARRAY element
        OVER, ATOP, CHOOSE, LEFT, and RIGHT tags, used with BOX
    Added test case for MATH elements to testsuite.

    *    Added more context checks for HTML 3 elements:
        -    OVERLAY must appear inside a FIG
        -    TD, TH, and TR can only appear in a TABLE
        -    ABOVE, BOX, BELOW, VEC, BAR, DOT, DDOT, HAT, TILDE, SQRT,
        ROOT, OF, ARRAY, TEXT, T, and BT can only appear in MATH
        -    LH must appear in OL, UL, or DL.
    Added some context test cases to testsuite.

    *    Fixed the bug where the VALIGN attribute was not recognized for the
    TD and TH elements of tables.  Bug report and fix from
    David Begley <[e-mail]>

    *    Changed a couple of the regular expressions to be associative
    arrays, for a slight speedup.

    *    Added a `required-context' warning, which is a generalized case
    of existing warnings such as `form-item'.  It specifies a required
    context for an element, such as the ROOT element can only appear
    in the MATH element.  The following warnings were removed:
        form-item
        select-option
        defn-list-elements
        list-item
    Code contributed by Axel Boldt <[e-mail]>

    *    Added -i switch to specify that case should be ignored when checking
    element tags.  This is equivalent to:
        weblint -d lower-case -d upper-case
    Suggested by Tom Neff <[e-mail]>

    *    Changed the wording of the `heading-order' warning to mention that
    this is a "bad style" warning.

    *    More updates to the netscape support:
        -    CELLSPACING attribute for TABLE
        -    CELLPADDING attribute for TABLE
        -    WIDTH attribute for TD and TH
        -    TEXT, LINK, VLINK, and ALINK attributes for BODY

    29-june-1995 neilb

    *    Updated the testsuite so individual tests can specify flags which
    should be added to the weblint command line, eg to enable the
    netscape extensions.

    *    Added two test cases to check that netscape HTML extensions are
    (only) correctly recognized when weblint is run with the netscape
    extension enabled.

    *    Finally got around to making weblint accept the BLINK element
    when the netscape extensions are enabled.
    Noted by Bruce Speyer <[e-mail]>.

    *    Fixed bug where <> would confuse weblint, resulting in spurious
    warnings.  Reported by Gil Citro, and others.  Added test case
    to the testsuite.

    *    Fixed bug in netscape support where the WIDTH attribute was not
    recognized for the HR element.

    *    Updated netscape support to include new attributes:
        -    START attribute for OL
        -    VALUE attribute for LI
        -    BGCOLOR attribute for BODY
    (noted by Richard Lloyd <[e-mail]>)

1.007

    26-june-1995 neilb

    *    Improved performance by adding /o modifier to appropriate regular
    expression matches.  Weblint on a fairly complex table went from
    ~8.9 seconds to ~1.9.  Suggested by Dana Jacobsen <[e-mail]>.
    Shame on me for not doing this in the first place!

    *    Fixed bug where the 'unknown-attribute' warning would never be
    generated for unknown element attributes.  Added test case to
    testsuite.  Bug reported by Dana Jacobsen <[e-mail]>.

    *    Fixed bug in testsuite where user's .weblintrc could be configured
    to make certain tests fail.  Now set WEBLINTRC = /dev/null, to
    over-ride user's configuration.
    Reported by Barry Bakalor <[e-mail]>

    *    Fixed bug where the <B> element was not recognized.  Added a simple
    test case to testsuite for the information type and font style
    elements (B, I, TT, CODE, etc).

    25-june-1995 neilb

    *    First cut at HTML 3 support.  All elements are supported, but not
    all the right context checks are performed yet (for example, a
    warning is not generated if you use something like <SQRT> outside of
    a MATH element, or <TR> outside of a TABLE.

    *    If you don't have a TITLE element, but *do* have a HEAD element,
    then you'll only get one warning now, instead of the previous two.

    *    Weblint no longer complains about not seeing the HTML element,
    unless you enable the 'html-outer' warning (which is enabled by
    default).  It used to generate an additional (unsuppressable)
    warning about expected HTML tag not seen.
    Reported by Chris Siebenmann <[e-mail]>.

    *    Fixed bug where obsolete elements generated warnings about unknown
    tags, and never generated the `obsolete' warning.
    Reported by Axel Boldt.

    *    Added -E switch, which specifies that warnings should be printed
    to STDERR rather than STDOUT.

    24-june-1995 neilb

    *    Added a regression testsuite for weblint, in test.pl.  Run with:
        % make test
    The status of each test (pass/fail) is printed to STDERR, with a more
    complete log written to weblint-test.log.

    *    Fixed bug in man page for `head-element' description.  It now says
    that the warning is `enabled' by default, instead of `head-element',
    which is what it said before.
    Reported by Anthony Thyssen <[e-mail]>

    *    Fixed bug where enabling the netscape extensions would result in
    VAR and NOBR not being recognized as legal.  Bug report and fix
    from David J. MacKenzie <[e-mail]>

    23-june-1995 neilb

    *    Added -t switch for terse output, to facilitate testing.
    If -t is specified, warnings are reported as:
        filename:line:id

    *    Fixed the bug where weblint would complain that the META element
    was not allowed to appear in the HEAD element.  In fact that's
    the only place it can appear :-)
    Reported by Thomas Leavitt <[e-mail]> and others.


1.005

    21-nov-1994 neilb

    *    Fixed bug whereby unknown tags were always given as </...>,
    whether they were opening or closing tags.
    (reported by Larry Virden <[e-mail]>)

    *    Changed the `bad-link' warning to be disabled by default, since
    there is at least one situation in which it will generate bogus
    warnings.

    20-nov-1994 neilb

    *    Giving the -R switch with no files/directories specified now
    defaults to `.', the current directory.
    (suggested by Barry Bakalor <[e-mail]>)

    *    Fixed bug whereby required attributes were being checked on closing
    tags as well as opening tags.
    (reported by Barry Bakalor <[e-mail]>)

    *    Fixed bugs in `bad-link' check for non-existent targets:
        -    mailto:
        -    news:
        -    directories
        -    absolute paths, eg cgi-scripts (HREF="/cgi-bin/foo")
    (reported by Barry Bakalor <[e-mail]>)

    *    Fixed typos in weblintrc.
    (reported by Barry Bakalor <[e-mail]>)

1.004

    19-nov-1994 neilb

    *    Added an Announce file to distribution, which contains verbose
    announcement for the current version, listing all new warnings and
    their identifiers.

    *    First attempt at check for potentially unclosed elements ---
    checking for:
        < ... < ... >
    for example:
        <A HREF="..." anchor text</A>
    Warning has identifier `unexpected-open'.  This might not catch all
    cases at the moment, since I didn't want it to generate bogus warnings
    where < appears in an attribute value (eg ALT="<-").

    *    Changed the 'expected-attribute' identifier to 'required-attribute',
    and added a warning with identifier 'expected-attribute'.  This is
    for elements which have no *required* attributes, but for which you
    expect to see at least one attribute, such as anchors.

    *    Added a Makefile, with targets for install, preview, tar, clean,
    and a postscript version of the man page.
    (suggested by Richard Lloyd <[e-mail]>)

    18-nov-1994 neilb

    *    Added support for `proposed' items: REL and REV attributes of anchors,
    META, DFN, STRIKE, and U.
    (noted by Robert Schmunk <[e-mail]>)

    17-nov-1994 neilb

    *    Added a check for relative local links, to generate a warning if
    the target does not exist.  Warning identifier: bad-link

    *    Added -d and -e switches to enable and disable warnings.
    The argument can be one or more warning identifiers, with multiple
    identifiers separated with commas.  For example:
        weblint -e upper-case foo.html
    A pseudo identifier `mixed-case' is now supported:
        weblint -e mixed-case foo.html
    Turns off upper-case and lower-case checking.

    *    Warning added for heading which is more than one level deeper than
    the most recent heading.  I.e.  <H1> followed by <H3> results in
    warning, with identifier 'heading-order'.
    (suggested by Bill Arnett <[e-mail]>)

    16-nov-1994 neilb

    *    Changed the extension switch from -e to -x, so that -e and -d
    can be used for enable/disable warning(s).

    15-nov-1994 neilb

    *    Added a check for an odd number of quotes in an element, so the
    following now generates a warning:
        <A HREF="http://www.foobar.com/>

    14-nov-1994 neilb

    *    If an element is not recognized, then any element attributes are
    not checked for validity.
    (suggested by Victor Parada <[e-mail]>)

    *    All keywords in the configuration file can now take multiple
    arguments.  I.e., you can enable multiple warnings with:
        enable mailto-link upper-case

    *    The illegal element check wasn't being performed on closing
    tags, so </XYZ> wouldn't generate a warning.
    (reported by Victor Parada <[e-mail]>)

    *    Added a sample configuration file `weblintrc', with
    comments describing everything which can be configured.
    Configuration matches the built-in defaults.

    *    Use of <!doctype ...> would generate a bunch of bogus whines.
    (reported by several people :-)

1.003

    11-nov-1994 neilb

    *    Added support for HTML extensions.  Currently only the
    netscape extensions are supported, either by:

        weblint -e netscape ....

    or, in your .weblintrc:

        # enable the netscape HTML extensions
        extension netscape

    Weblint will not complain that <CENTER> is an unknown element,
    and also knows about the additional element attributes.

    *    Fixed the bug in the -R code whereby it would get confused
    about where it was.
    (reported by Victor Parada <[e-mail]>, and
    Bob Friesenhahn <[e-mail]>)

    *    Removed the generic context check added on 6-nov-1994.
    I need to learn more about implied context before this is
    added back in.  It currently whines about *everything* :-(

    6-nov-1994 neilb

    *    Generalized the context checks;  they are now table driven,
    and based on the HTML spec.  Warning identifier is
    `illegal-context'.

    5-nov-1994 neilb

    *    Made the usage slightly more verbose, giving example usage.
    (suggested by Douglas Brick <[e-mail]>)

    *    Added a check for illegal elements, with warning identifier
    of 'unknown-element', enabled by default.  So
        <¥PRE> and <CENTER>
    will generate this warning.  (suggested by Joerg Heitkoetter
    <Joerg.Heitkoetter¥@germany.eu.net>)

    *    For non-nestable elements (such as anchors), the warning
    now gives the line number of the still open element.

    *    Weblint now correctly recognizes SGML comments where there
    is whitespace between the -- and > closing the comment. Eg:
        <!-- this is a valid comment --   >
    (reported by Paul Black <[e-mail]>)

    3-nov-1994 neilb

    *    Removed the warning with identifier 'tag-args':
        expected argument for tag <...>.
    and replaced it with a general check for required attributes,
    with identifier 'expected-attribute':
        sample.html(9): SRC attribute is required for <IMG>.

    *    Added a -s command-line switch, for short warnings.  Short
    warnings do not include the filename:
        line 5: no <TITLE> in HEAD element.
    (suggested by Clay Webster <[e-mail]>)

    *    Added a check and warning (identifier: leading-whitespace)
    for whitespace between < and tag name, for example:
        < TITLE>
    will generate warning:
        Should not have whitespace between "<" and "TITLE>".

    *    The usage statement is now printed if weblint is invoked
    without any command-line arguments.

    *    Fixed bug whereby
        <IMG SRC="foo.gif" ISMAP ALT="alt text">
    would generate a warning that element had no ALT text.

    *    Added a check for legal attributes.  So the following
        <A HROF="...">
    generates a warning:
        Unknown attribute "HROF" for element <A>.
    with warning identifier of 'unknown-attribute'.

    *    Messages are now written to STDOUT rather than STDERR.

1.002

    2-nov-1994 neilb

    *    Now correctly (or more correctly at least) recognizes SGML
    comments, and doesn't get confused by markup embedded in
    comments.  Added a new warning for markup embedded in a
    comment, since this confuses some browsers.  The warning,
    with identifier 'markup-in-comment', is enabled by default.

    *    Modified the checks on element closing tags </...>,
    performed for </HEAD>, </BODY> and </HTML> -- the following
    used to generate a bogus warning that no </UL> was seen:

        <HTML><HEAD><TITLE>sample</TITLE></HEAD><BODY>
        <UL>
        <LI><I>unclosed italic
        </UL>
        </BODY></HTML>

    *    Slight re-arrangement of man page sections, to follow
    traditional UNIX conventions (reported by Joerg Heitkoetter
    <[e-mail]>)

    *    No longer complains if you have more than one ADDRESS
    element on a page.

    1-nov-1994 neilb

    *    added a -R switch, which is used to recurse down directories,
    checking any files found with a file extension of .html or
    .htm; for example:
        weblint -R .
    Weblint now depends on find.pl from the standard perl library.
    (suggested by Thomas Leavitt <[e-mail]>)

    *    changed logic of the check for elements which can and can't
    appear in the HEAD element.  Weblint previously complained
    that ISINDEX could only appear in the HEAD, which was not
    true (reported by Victor Parada <[e-mail]>)

    29-oct-1994 neilb

    *    attributes were not being seen in multi-line tags if they
    appeared after the first newline.  Eg:
        <IMG SRC="foo.gif"
        ALT="alt text>
    generated a warning that the IMG had no ALT text.
    (reported by Barry Bakalor <[e-mail]>)

    *    Now handles whitespace around the = of tag attributes.
    The following used to generate a warning:
        <IMG SRC = "foo.gif" ALT="alt text>
    (reported by Barry Bakalor <[e-mail]>)

    *    No longer complains about comments in the HEAD element.
    (reported by Douglas Brick <[e-mail]>)

    *    Certain variables were not declared local to the WebLint()
    function, which meant that when weblint'ing more than one
    file on the command-line, some state variables would roll
    over to the next file, causing bogus warnings.
    (reported by Barry Bakalor <[e-mail]>)

    *    Now handles case where a tag attribute does not have
    a value (attribute = value), as is the case with ISMAP.
    Weblint was getting confused over things like:
        <IMG SRC="foo.gif" ISMAP ALT="alt text">
    and complaining that the IMG had no ALT text.
    (reported by Richard Lloyd <[e-mail]>)

    *    If you give `-' as a filename, weblint will read from
    standard input.  Warnings will be given for `stdin'.
    (suggested by Ryan Waldron <[e-mail]>)


1.001

    24-oct-1994 neilb

    *    Added a man page (initial man page supplied by
    Juergen Schoenwaelder <[e-mail]>)

    *    Added a check for FORM elements:
      - INPUT, SELECT, and TEXTAREA must appear in a FORM.
      - OPTION must be within a SELECT element.

    *    Added code which checks for overlapped elements.  E.g.:
        <H1> ... <A HREF="foobar"> ... </H1> </A>
    This now results in one warning rather than six :-)
    Multiply overlapped elements (more than two) don't always
    generated the `correct' number of warnings, but you should
    get at least one :-)

    *    Improved check for unclosed elements.  Following example
    now generates one warning, instead of the multitude
    generated by weblint 1.0:
        <HTML><HEAD><TITLE>...</TITLE></HEAD>
        <BODY> <B> unclosed bold element
        </BODY></HTML>

    23-oct-1994 neilb

    *    fixed the whine generated if you have a <!DOCTYPE ...>
    at the start of your page.

    *    added support for a configuration file.  WEBLINTRC,
    or $HOME/.weblintrc.  Changed the whine() function to use
    warning identifiers.  Defined whines, with identifiers,
    and default enabling are stored beyond the end of the script.
    Can enable or disable warnings in your .weblintrc.

    *    added check for illegally nested elements (eg anchors).

    *    additional check for items which should not appear in HEAD.

    *    check that <DT> and <DD> appear in a definition list (DL).

    *    added COMMENT to list of obsolete elements.

    *    added check for elements which must be in a FORM element.

    *    added check for <LINK REV=MADE HREF="mailto:...">,
    which is not enabled by default.

    21-oct-1994 neilb

    *    added check for LI, that it appears within DIR, MENU,
    OL or UL elements

    *    Fixed bug whereby weblint wasn't seeing tags with
    embedded newlines.  Eg:
        <A
        HREF="...."
        >

    20-oct-1994 neilb

    *    fixed bug in the code which keeps track of currently `open'
    elements.  It was getting confused on line numbers.
    (reported by Barry Bakalor <[e-mail]>)

    *    checks at end of file for unclosed elements were giving
    message:
        tag <...> has no matching </HTML>.
    rather than correct closing tag.
    (reported by Barry Bakalor <[e-mail]>)
