<h4>Public Email List for Tidy: <<a
|
|
href="mailto:html-tidy@w3.org">html-tidy@w3.org</a>></h4>
|
|
|
|
<p>I have set up an archived mailing list devoted to Tidy. To
|
|
subscribe send an email to html-tidy-request@w3.org with the word
|
|
subscribe in the subject line (include the word unsubscribe if
|
|
you want to unsubscribe). The <a
|
|
href="http://lists.w3.org/Archives/Public/html-tidy/">archive</a>
|
|
for this list is accessible online. Please use this list to
|
|
report errors or enhancement requests.</p>
|
|
|
|
<h3>Things awaiting further attention</h3>
|
|
|
|
<p>These have been moved to the <a href="pending.html">pending
|
|
page</a>, which includes all the suggestions for improvements and
|
|
bug fixes. I am looking for volunteers to help with these as my
|
|
current workload means that I don't get much time left to work on
|
|
HTML Tidy.</p>
|
|
|
|
<h2>August 2000</h2>
|
|
|
|
<p>Ann Navarro comments that the "appears to" message is
|
|
confusing when it differs from the doctype declaration. Perhaps
|
|
it would make sense to also report the doctype? Tidy will now
|
|
report the FPI when present, and then the apparent version as
|
|
deduced from the elements and attributes present in the rest of
|
|
the document.</p>
|
|
|
|
<p>John Russell sent in an example which featured a script
|
|
element in a frameset document where the script element appears
|
|
after the head and before the frameset. This is I believe
|
|
illegal, but Tidy proceeds to do the dumb thing discarding the
|
|
frameset element! I think it should move the script element into
|
|
the head and continue. This is now implemented.</p>
|
|
|
|
<p>Jacques Steyn says that Tidy doesn't know about the HTML4 char
|
|
attribute for col elements. Now fixed.</p>
|
|
|
|
<p>Carlos Piqueres Ayela would like Tidy to detect all cases of
|
|
repeated attributes, e.g. repeated valign in table cells. This
|
|
was introduced a few releases back, but I forgot to apply this
|
|
check for the elements with special purpose attribute checking
|
|
methods. Now fixed. Tidy will issue a warning for each repeated
|
|
attribute. In principle Tidy could merge repeated class
|
|
attributes, but this will require more work. My apologies to
|
|
Carole Mah for not having the time to do this now.</p>
|
|
|
|
<p>Henry Zrepa would like an option to suppress whitespace
|
|
munging on selected attributes used for legacy scripts passed as
|
|
parameters to plugins. I have added a new boolean option
|
|
"literal-attributes" which can be set to yes to preserve
|
|
whitespace within attribute values. A better solution would be to
|
|
make this selectable on a per element basis, but I don't have
|
|
time to explore this now.</p>
|
|
|
|
<p>Edward Zalta spotted that Tidy always removed newlines
|
|
immediately after start tags even for empty elements such as img.
|
|
An exception to this rule is the br element. Now fixed.</p>
|
|
|
|
<h2>July 2000</h2>
|
|
|
|
<p>Edward Zalta sent me an example, where Tidy was inadvertently
|
|
wrapping lines after an image element. The problem was a
|
|
conditional in pprint.c, now fixed.</p>
|
|
|
|
<p>Andy Quick offered a bug fix for the AddClass() function in
|
|
clean.c. My thanks to Terry Teague for bringing this to my
|
|
attention. Davor Golek reported a problem with the -f option. I
|
|
discovered a bug in line 898 in tidy.c, now fixed.</p>
|
|
|
|
<h2>June 2000</h2>
|
|
|
|
<p>Fixed bug in NormalizeSpaces (== in place of =) on line
|
|
1699.</p>
|
|
|
|
<p>I have added a new config option "gnu-emacs" following a
|
|
suggestion by David Biesack. The option changes the way errors
|
|
and warnings are reported to make them easier for Emacs to
|
|
parse.</p>
|
|
|
|
<p>Tony Leneis noticed that Tidy didn't know that width and
|
|
height attributes on the img element aren't allowed in HTML 2.0.
|
|
He also noted that Tidy didn't know that HTML 2.0 allows img as a
|
|
direct child of body. Both of these bugs are now fixed.</p>
|
|
|
|
<p>I have refined CanPrune() to block pruning empty elements with
|
|
if they have id or name attributes. Previously any attribute
|
|
would prevent an empty element from being pruned. The rationale
|
|
is that such empty elements are placed there to be filled
|
|
dynamically by a script. This is unlikely to occur unless the
|
|
element can be referenced via id or name.</p>
|
|
|
|
<p>Denis Barbier sent in details patches that suppresses numerous
|
|
warnings when compiling tidy, especially:</p>
|
|
|
|
<ul>
|
|
<li>`static' declaration of subroutines when possible</li>
|
|
|
|
<li>initialization of variables when it might be used before
|
|
assignment</li>
|
|
|
|
<li>change name of local variables when it overrides global ones
|
|
(count, index, fp)</li>
|
|
|
|
<li>suppression of long jump, buffers are closed in
|
|
FatalError</li>
|
|
</ul>
|
|
|
|
<p>Fixed memory leak in CoerceNode. My thanks to Daniel Persson
|
|
for spotting this. Tapio Markula asked if Tidy could give
|
|
improved detection of spurious </ in script elements. Now
|
|
done.</p>
|
|
|
|
<p>My thanks to John Russell who pointed out that Tidy wasn't
|
|
complaining about src attributes on hr elements. My thanks to
|
|
Johann-Christian Hanke who spotted that Tidy didn't know about
|
|
the Netscape wrap attribute for the text area element.</p>
|
|
|
|
<p>Sebastian Lange has contributed a perl wrapper for calling
|
|
Tidy from your perl scripts, see <a
|
|
href="sl-tidy.pl">sl-tidy.pl</a>.</p>
|
|
|
|
<p>Stephen Reynolds would like comments that end with a line
|
|
break to retain this property when tidied. I have added a new
|
|
boolean property to the node structure which is set by the end
|
|
comment parser in lexer.c and acted on by the comment formatting
|
|
code in pprint.c</p>
|
|
|
|
<p>Henry Zrepa (sp?) reported that XHTML <param\> elements
|
|
were being discarded. This was due to an error in ParseBlock, now
|
|
fixed.</p>
|
|
|
|
<p>Carole E. Mah noted that Tidy doesn't complain if there are
|
|
two or more title elements. Tidy will now complain if there are
|
|
more than one title element or more than one base element.</p>
|
|
|
|
<h2>May 2000</h2>
|
|
|
|
<p>Following a suggestion by Julian Reschke, I have added an
|
|
option to add xml:space="preserve" to elements such as pre, style
|
|
and script when generating XML. This is needed if these elements
|
|
are to be correctly parsed without access to the DTD.</p>
|
|
|
|
<h2>April 2000</h2>
|
|
|
|
<p>Randy Wacki notes that IsValidAttribute() wasn't checking that
|
|
the first character in an attribute name is a letter. Now
|
|
fixed.</p>
|
|
|
|
<p>Jelks Cabaniss wants the naked li style hack made into an
|
|
option or at least tweaked to work in IE and Opera as well as
|
|
Navigator. Sadly, even Navigator 6 preview 1 replicates the buggy
|
|
CSS support for lists found in Navigator 4. Neither Navigator 6
|
|
nor IE5 (win32) supports the CSS marker-offset property, and so
|
|
far I have been unable to find a safe way to replicate the visual
|
|
rendering of naked li elements (ones without an enclosing ul or
|
|
ol element). As a result I have opted for the safer approach of
|
|
adding a class value to the generated ul element
|
|
(class="noindent") to keep track of which li's weren't properly
|
|
enclosed.</p>
|
|
|
|
<p>Rick Parsons would like to be able to use quote marks around
|
|
file names which include spaces, when specifying files in the
|
|
config file. Currently, this only effects the "error-file"
|
|
option. I have changed that to use ParseString. You can specify
|
|
error files with spaces in their names.</p>
|
|
|
|
<p>Karen Schlesinger would like tidy to avoid pruning empty span
|
|
elements when these have id attributes, e.g. for use in setting
|
|
the content later via the DOM. Done.</p>
|
|
|
|
<p>I have modified GetToken() to switch mode from
|
|
IgnoreWhitespace to MixedContent when encountering non-white
|
|
textual content. This solves a problem noticed by Murray
|
|
Longmore, where Tidy was swallowing white space before an end
|
|
tag, when the text is the first child of the body element.</p>
|
|
|
|
<p>Tidy needs to check for text as direct child of blockquote
|
|
etc. which isn't allowed in HTML 4 strict. This could be
|
|
implemented as a special check which or's in transitional into
|
|
the version vector when appropriate.</p>
|
|
|
|
<p>ParseBlock now recognizes that text isn't allowed directly in
|
|
the block content model for HTML strict. Furthermore, following a
|
|
suggestion by Berend de Boer, a new option enclose-block-text has
|
|
the same effect as enclose-text but also applies to any block
|
|
element that allows mixed content for HTML transitional but not
|
|
HTML strict.</p>
|
|
|
|
<p>Jany Quintard noted that Tidy didn't realise the width and
|
|
height attribute aren't allowed on table cells in HTML strict
|
|
(it's fine on HTML transitional). This is now fixed. Nigel
|
|
Wadsworth wanted border on table without a value to be mapped
|
|
into border="1". Tidy already does this but only if the output is
|
|
XHTML.</p>
|
|
|
|
<p>Jelks Cabaniss wanted Tidy to check that a link to a external
|
|
style sheet includes a type attribute. This is now done. He also
|
|
suggested extending the clean operation to migrate presentation
|
|
attributes on body to style rules. Done.</p>
|
|
|
|
<h2>March 2000</h2>
|
|
|
|
<p>I have been working on improving the Word2000 cleanup, but
|
|
have yet to figure out foolproof rules of thumb for recognizing
|
|
when paragraphs should be included as part of ul or ol lists.
|
|
Tidy recognizes the class "MsoListBullet" which Word seems to
|
|
derive from the Word style named "List Bullet". I have yet to
|
|
deal with nested lists in Word2000. This is something I was able
|
|
to deal with for html exported from Word97, but it looks like
|
|
being significantly harder to deal with for Word2000.</p>
|
|
|
|
<p>Tidy is now able to create a pre element for paragraphs with
|
|
the style "Code". So try to use this style in your Word documents
|
|
for preformatted text. Tidy strips out the p tags and coerces
|
|
non-breaking spaces to regular spaces when assembling the pre
|
|
element's content.</p>
|
|
|
|
<p>I would very much welcome any suggestions on how to make the
|
|
Word2000 clean up work better!</p>
|
|
|
|
<p>Changed Style2Rule() in clean.c to check for an existing class
|
|
attribute, and to append the new class after a space. Previously
|
|
you got two class attributes which is an error</p>
|
|
|
|
<p>Changed default for add-xml-pi to no since this was causing
|
|
serious problems for several browsers.</p>
|
|
|
|
<p>Joakim Holm notes that tidy crashes on ASP when used for
|
|
attributes. The problem turned out to be caused by
|
|
CheckUniqueAttribute() which was being inappropriate apply to ASP
|
|
nodes.</p>
|
|
|
|
<p>John Bigby noted that Tidy didn't know about Microsoft's data
|
|
binding feature. I have added the corresponding attributes to the
|
|
table in attr.c and tweaked CanPrune() so that empty elements
|
|
aren't deleted if they have attributes.</p>
|
|
|
|
<p>Tidy is now more sophistocated about how it treats nested
|
|
<b>'s etc. It will prune redundant tags as needed. One
|
|
difficulty is in knowing whether a start tag is a typo and should
|
|
have been an end-tag or whether it starts a nested element. I
|
|
can't think of a hard and fast rule for this. Tidy will coerce a
|
|
<b> to </b> except when it is directly after a
|
|
preceding <b>.</p>
|
|
|
|
<p>Bertilo Wennergren noted that Tidy lost <frame/>
|
|
elements. This has now been fixed with a patch to
|
|
ParseFrameSet.</p>
|
|
|
|
<h2>February 2000</h2>
|
|
|
|
<p>Dave Bryan spotted an error in pprint.c which allowed some
|
|
attributes to be wrapped even when wrap-attributes was set to no.
|
|
On a separate point, I have now added a check to issue a warning
|
|
if SYSTEM, PUBLIC, //W3C, //DTD or //EN are not in upper
|
|
case.</p>
|
|
|
|
<p>Tidy now realises that inline content and text is not allowed
|
|
as a direct child of body in HTML strict.</p>
|
|
|
|
<p>Dave Bryan also noticed that Tidy was preferring HTML 4.0 to
|
|
4.01 when doctype is set to strict or transitional, since the
|
|
entries for 4.0 appeared earlier than those for 4.01 in the table
|
|
named W3C_Version in lexer.c. I have reversed the order of the
|
|
entries to correct this. Dave also spotted that ParseString() in
|
|
config.c is erroneously calling NextProperty() even though it has
|
|
already reached the end of the line.</p>
|
|
|
|
<h2>January 2000</h2>
|
|
|
|
<p>I have added a new function ApparentVersion() which takes the
|
|
doctype into account as well as other clues. This is now used to
|
|
report the apparent version of the html in use.</p>
|
|
|
|
<p>Thanks to the encouragement of Denis Barbier, I finally got
|
|
around to deal with the extra bracketing needed to quiet gcc
|
|
-Wall. This involved the initialization of the tag, attribute and
|
|
entity tables, and miscellaneous side-effecting while and for
|
|
loops.</p>
|
|
|
|
<p>PPrintXMLTree has been updated so that it only inserts line
|
|
breaks after start tags and before end tags for elements without
|
|
mixed content. This brings Tidy into line with current wisdom for
|
|
XML editors. My thanks to Eric Thorbjornsen for suggesting a fix
|
|
to FindTag that ensures that Tidy doesn't mistreat elements
|
|
looking like html.</p>
|
|
|
|
<p><table border> is now converted to
|
|
<table border="1"> when converting to XHTML.</p>
|
|
|
|
<p>I have added support for CDATA marked sections which are
|
|
passed through without change, e.g.</p>
|
|
|
|
<pre>
|
|
<![CDATA[ .. markup here has no effect .. ]]>
|
|
</pre>
|
|
|
|
<p>A number of people were interested in Tidied documents be
|
|
marked as such using a meta element. Tidy will now add the
|
|
following to the head if not already present:</p>
|
|
|
|
<pre>
|
|
<meta name="generator" content="HTML Tidy, see www.w3.org">
|
|
</pre>
|
|
|
|
<p>If you don't want this added, set the option tidy-mark to
|
|
no.</p>
|
|
|
|
<p>In the January 12th release, ParseXMLElement screwed up on
|
|
doctypes and toplevel comments, causing a memory exception. This
|
|
has now been fixed. PPrintXMLTree now uses zero indent for
|
|
comments to avoid progressive indentation as an XML document is
|
|
repeatedly tidied. I have added a blank line after elements
|
|
unless they are the last in the parent's content.</p>
|
|
|
|
<p>Johnny Lee reports that Tidy didn't realise that HTML4 allows
|
|
the object element in the document head. Now fixed. Rainer
|
|
Gutsche noticed that Tidy wasn't moving an initial space after a
|
|
anchor start tag to just before the element. I have streamlined
|
|
the trimming of spaces.</p>
|
|
|
|
<p>Johannes Zellner spotted that newly declared preformatted tags
|
|
weren't being treated as such for XML documents. Now fixed.</p>
|
|
|
|
<h2>December 1999</h2>
|
|
|
|
<p>Tidy now generates the XHTML namespace and system identifier
|
|
as specified by the current <a
|
|
href="http://www.w3.org/TR/xhtml1/">XHTML Proposed
|
|
Recommendation</a>. In addition it now assumes the latest version
|
|
of HTML4 - HTML 4.01. This fixes an omission in 4.0 by adding the
|
|
name attribute to the img and form elements. This means that
|
|
documents with rollovers and smart forms will now validate!</p>
|
|
|
|
<p>James Pickering noticed that Tidy was missing off the xhtml-
|
|
prefix for the XHTML DTD file names in the system identifier on
|
|
the doctype. This was a recent change to XHTML. I have fixed
|
|
lexer.c to deal with this.</p>
|
|
|
|
<p>This release adds support for <a
|
|
href="http://developer.netscape.com/viewsource/schroder_template/schroder_template.html">
|
|
JSTE</a> psuedo elements looking like: <# #>. Note
|
|
that Tidy can't distinguish between ASP and JSTE for psuedo
|
|
elements looking like: <% %>. Line wrapping of this
|
|
syntax is inhibited by setting either the wrap-asp or wrap-jste
|
|
options to no.</p>
|
|
|
|
<p>Thanks to Jacek Niedziela, The Win32 executable for tidy is
|
|
now able to example wild cards in filenames. This utilizes the
|
|
setargv library supplied with VC++.</p>
|
|
|
|
<p>Jonathan Adair asked for the hashtables to be cleared when
|
|
emptied to avoid problems when running Tidy a second time, when
|
|
Tidy is embedded in other code. I have applied this to
|
|
FreeEntities(), FreeAttrTable(), FreeConfig(), and
|
|
FreeTags().</p>
|
|
|
|
<p>Ian Davey spotted that Tidy wasn't deleting inline emphasis
|
|
elements when these only contained whitespace (other than
|
|
non-breaking spaces). This was due to an oversight in the
|
|
CanPrune() function, now fixed.</p>
|
|
|
|
<p>Michel Lemay spotted some bugs in if statements and provided
|
|
some sample html files that caused Tidy to crash. On further
|
|
study, I found a bug in the code that moves font elements inside
|
|
anchors. I have fixed this and added a new method to test the
|
|
tree for internal consistency in its bidirectional links:
|
|
CheckNodeIntegrity().</p>
|
|
|
|
<p>I have also refined the code for handling noframes to make it
|
|
more robust. It will now handle noframes within a body within a
|
|
noframes etc. (something permitted by HTML4). It will also
|
|
recover if the noframes end tag is missing or is in the wrong
|
|
place.</p>
|
|
|
|
<p>I have fleshed out the table for mapping characters in the
|
|
Windows Western character set into Unicode, see Win2Unicode[].
|
|
Yahoo was, for example, using the Windows Western character for
|
|
bullet, which is in Unicode is U+2022.</p>
|
|
|
|
<p>David Halliday noticed that applets without any content
|
|
between the start and end tags were being pruned by Tidy. This is
|
|
a bug and has now been fixed.</p>
|
|
|
|
<p>I have changed the way Tidy handles empty paragraphs when the
|
|
drop-empty-paras is set to no. HTML4 doesn't allow empty
|
|
paragraphs so I am now replacing them by a pair of br elements,
|
|
so that the formatting is preserved. When drop-empty-paras is set
|
|
to yes, empty paragraphs are simply removed.</p>
|
|
|
|
<p>Darren Forcier asked for a way to suppress fixing up of
|
|
comments when these include adjacent hyphens since this was
|
|
screwing up Cold Fusion's special comment syntax. The new option
|
|
is called: <i>fix-bad-comments</i> and defaults to yes.</p>
|
|
|
|
<p>Using Michel's examples I have improved the way the table
|
|
parser deals with unexpected content. This is now consistently
|
|
moved before the table, or to the head element as appropriate.
|
|
Microsoft and Netscape differ in how an unclosed blockquote
|
|
renders when found at the table or tr level. Netscape indents the
|
|
table but Microsoft does not. This is getting too tricky for me
|
|
to deal with!</p>
|
|
|
|
<p>Using a sample page from Yahoo, I discovered that Netscape
|
|
Navigator doesn't implement the text-align style property on tr
|
|
or table elements. As a result I have added a special check for
|
|
this in BlockStyle() to avoid translating the align attribute on
|
|
tr or table into a style rule.</p>
|
|
|
|
<p>Richard Allsebrook would like to be able to map b/i to
|
|
strong/em without the full clean process being invoked. I have
|
|
therefore decoupled these two options. Note that setting
|
|
logical-emphasis is also decoupled from drop-font-tags.</p>
|

|
<h2>30th November 1999</h2>
|
|
|
|
<p>This is an interim release to provide a bug fix for a bug
|
|
introduced earlier in the month. I have fixed a bug in the
|
|
emphasis code which looks for start tags Which are most likely
|
|
intended as end tags. This bug only appeared in the November
|
|
release and could cause a crash or indefinite looping. My thanks
|
|
to a respondent calling himself "Michael" who provided a
|
|
collection of files that allowed me to track this down.</p>
|
|
|
|
<p>I have also added page transition effects for the slide maker
|
|
feature. The effects are currently only visible on IE4 and above,
|
|
and take advantage of the meta element. I will provide an option
|
|
to select between a range of transition effects in the next
|
|
release.</p>
|
|
|
|
<h2>November 1999</h2>
|
|
|
|
<p>David Duffy found a case causing Tidy to loop indefinitely.
|
|
The problem occurred when a blocklevel element is found within a
|
|
list item that isn't enclosed in a ul or ol element. I have added
|
|
a check to ParseList to prevent this.</p>
|
|
|
|
<p>Takuya Asada tells me that in Raw mode Tidy is incorrectly
|
|
mapping 0xA0 to the entity   causing problems for Shift_JIS
|
|
etc. Now fixed. Larry Virden reported a problem with ParseConfig
|
|
when one of the arguments was null. I have added a check for
|
|
this.</p>
|
|
|
|
<p>Thomas McGuigan notes that Tidy issues a warning for noframes
|
|
elements without a body element. HTML4 is defined so that the
|
|
content of the noframes element is restricted to a single body
|
|
element. However, it also allows you to omit the start and end
|
|
tags for body, something that isn't allowed for XHTML. I have
|
|
changed the code to only issue the warning when generating
|
|
XML.</p>
|
|
|
|
<p>Added new --version or -v option that reports the release date
|
|
to the error stream. ParseConfig() now returns false if it
|
|
doesn't use the parameter. This avoids the next argument on the
|
|
command line from being swallowed inadvertently, e.g. for unknown
|
|
options. Tidy now warns about unrecognized options.</p>
|
|
|
|
<p>I have revised the way Tidy deals with comments to avoid
|
|
problems with repeated hyphens. First "--" is illegal in XML, and
|
|
second, the comment syntax for SGML is very error prone when it
|
|
comes to when and where you can use hyphens. As a result, Tidy
|
|
will now replace repeated hyphens with "=" characters. My thanks
|
|
to Yudong Yang and Randy Waki for their input on this.</p>
|
|
|
|
<p>Emphasis start tags will now be coerced to end tags when the
|
|
corresponding element is already open. For instance
|
|
<u>...<u>. This behavior doesn't apply to font tags
|
|
or start tags with attributes. My thanks to Luis M. Cruz for
|
|
suggesting this idea.</p>
|
|
|
|
<p>Jonathan Adair would like Tidy to warn when the same attribute
|
|
appears more than once in the same element. This is an error for
|
|
both SGML and XML. The best way to make this check would be to
|
|
sort the attributes and look for duplicate entries. Other people
|
|
have asked for the attributes to be sorted, but I need further
|
|
input on the appropriate sort order. As an interim solution, Tidy
|
|
uses a simple test which generates n+1 warnings if an attribute
|
|
is repeated n times.</p>
|
|
|
|
<h2>October 1999</h2>
|
|
|
|
<p>On Unix systems you can get Tidy to look for a config file in
|
|
~/.tidyrc or ~your/.tidyrc etc. when the HTML_TIDY environment
|
|
variable isn't set. To enable this feature don't forget to
|
|
uncomment SUPPORT_GETPWNAM in the platform.h file. This feature
|
|
won't work on Windows. My thanks to Todd Lewis who contributed
|
|
the code.</p>
|
|
|
|
<p>Darren Forcier reports that Cold Fusion uses the following
|
|
syntax:</p>
|
|
|
|
<pre>
|
|
<CFIF True IS True>
|
|
This should always be output
|
|
<CFELSE>
|
|
This will never output
|
|
</CFIF>
|
|
</pre>
|
|
|
|
<p>After declaring the CFIF tag in the config file, Tidy was
|
|
screwing up the Cold Fusion expression syntax, mapping 'True' to
|
|
'True=""' etc. My fix was to leave such pseudo attributes
|
|
untouched if they occur on user defined elements.</p>
|
|
|
|
<p>Jelks Cabaniss noticed that Tidy wasn't adding an id attribute
|
|
to the map element when converting to XHTML. I have added
|
|
routines to do this for both 'a' and 'map'. The value of the id
|
|
attribute is taken from the name attribute.</p>
|
|
|
|
<p>Larry Cousin noted that Tidy is now screwing up on option
|
|
elements. This proved to be a recently introduced error, which I
|
|
have now fixed. Peter Ruevski forwarded an example that caused
|
|
Tidy to loop endlessly. The problem was caused by an ol start tag
|
|
followed by a b start tag and then an li element. I have solved
|
|
the problem with a fix to ParseBlock.</p>
|
|
|
|
<p>I have revised the way Tidy deals with unexpected content in
|
|
lists. Tidy now wraps such content in list items with the style
|
|
attribute set to "list-style: none" to suppress list bullets. If
|
|
an li element is found unexpectedly in the body or block-level
|
|
content, it is wrapped into a ul element with the style attribute
|
|
set to "margin-left: -2em". This provides a closer match to the
|
|
observed rendering on current browsers. I use a couple of
|
|
postprocessing steps (List2BQ and BQ2Div) to further clean this
|
|
up to use div elements. My thanks to Thomas Ribbrock for sending
|
|
me a challenging example that led me to this solution.</p>
|
|
|
|
<p>A number of people have asked for a config option to set the
|
|
alt attribute for images when missing. The alt-text property can
|
|
now be used for this purpose. Please note that YOU are
|
|
responsible for making your documents accessible to people who
|
|
can't view the images!</p>
|
|
|
|
<p>Terry Teague spotted a bug in ParseConfigFile() that prevented
|
|
Tidy from parsing more that one file. This has been fixed by
|
|
setting the char buffer to zero in the call to InitConfig()
|
|
before parsing. Terry also noted a few places where I had slipped
|
|
back into using malloc and free rather than MemAlloc and MemFree,
|
|
now fixed.</p>
|
|
|
|
<p>Bjoern Hoehrmann notes that the September 27th release mapped
|
|
empty paragraphs to br elements, which introduces extra
|
|
whitespace in IE and Navigator. The former behavior to strip
|
|
empty paragraphs is as per HTML4 and works fine on most browsers
|
|
with the exception of Lynx. I have reverted to stripping empty
|
|
P's, but have added an option to leave them alone.</p>
|
|
|
|
<p>Bjoern also drew my attention to a bug in the September
|
|
release where table content is lacking a preceding td or th start
|
|
tag. Tidy moves such content to before the table element to match
|
|
the observed rendering. This is now working as planned. I have
|
|
tweaked the printing behavior when the omit end tags option is
|
|
set. It now omits the </html> as well as the optional start
|
|
tags for html, head and body.</p>
|
|
|
|
<p>Pao-Hsi Huang had problems with the contents of the option
|
|
element being discarded. I was unable to reproduce this problem,
|
|
but did notice that I unintentionally preserving newlines within
|
|
option text. This is now fixed. Shane Harrelson spotted that
|
|
table cells containing a single font element, when cleaned
|
|
dropped the font element without getting the corresponding style.
|
|
Now fixed via a tweak to InlineStyle().</p>
|
|
|
|
<p>Andre Hinrichs wanted Tidy to do a better job on font elements
|
|
with relative size changes. This is in fact rather tricky.
|
|
Currently, Tidy uses percentage scaling values for fonts rather
|
|
than the enumeration defined by CSS [xx-small | x-small | small |
|
|
medium | large | x-large | xx-large]. The first problem is to
|
|
match these 7 values onto the 6 define by the font element. The
|
|
next problem is caused by the fact that CSS doesn't provide
|
|
matching relative font size values that you could match to the
|
|
ones defined for the font element. I have done my best using
|
|
percentage values, base on tests with IE and Navigator. If anyone
|
|
can come up with a better approach, please let me know.</p>
|
|
|
|
<p>Tom Berger reported a problem when quote-marks was set to yes.
|
|
Using his test file everything is now working fine. Several
|
|
people asked for a way to turn off line wrapping. Tidy will now
|
|
interpret zero as meaning disable wrapping. Johannes Zellner
|
|
wants to include some tcl code in his XML markup and asks for a
|
|
way define new tags that behave in the same way as HTML's pre
|
|
element. The new option is new-pre-tags.</p>
|
|
|
|
<h2>September 1999</h2>
|
|
|
|
<p>Tidy will now add a type attribute to the style and script
|
|
attributes when this is missing. Tidy examines the language
|
|
attribute to determine what media type to use. I have also added
|
|
code to create an id attribute for anchors when a name attribute
|
|
is present, and to report a warning if id and name don't
|
|
match.</p>
|
|
|
|
<p>Added support for cleaning up HTML generated by Microsoft Word
|
|
2000 when you save as "Web Page". When you set "word-2000: yes"
|
|
Tidy makes a Herculean effort to clean up the mess created when
|
|
Word 2000 exports to HTML. Word bulks out HTML with presentation
|
|
information that allows it to round-trip documents between HTML
|
|
and Word without lost of information. This makes the HTML hard to
|
|
edit and can cause some very popular browsers to crash! I haven't
|
|
dealt with the VML markup Word uses for line drawings.</p>
|
|
|
|
<p>Applied fix to InsertNodeAfterElement() to set
|
|
node->next->prev. My thanks to "Advocate" for this. This
|
|
was only encountered when dealing with PRE tags containing
|
|
content illegal for PRE. (Called twice by ParsePre to move
|
|
illegal PRE content to be a later sibling of PRE, then open PRE
|
|
again afterward)</p>
|
|
|
|
<p>Change to table row parser so that when Tidy comes across an
|
|
empty row, it inserts an empty cell rather than deleting it. This
|
|
is consistent with browser behavior and avoids problems with
|
|
cells that span rows.</p>
|
|
|
|
<p>Baruch Even sent extensive patches for improved support for
|
|
the PHP preprocessing psuedo tags. You can now use the 'wrap-php:
|
|
no' to suppress line wrapping within PHP instructions. In the
|
|
process of this work, I have created a new function InsertMisc()
|
|
for dealing with comments, processing instructions, ASP and
|
|
PHP.</p>
|
|
|
|
<p>I have update the table of tags to include additional
|
|
proprietary tags such as server, ilayer, layer, nolayer and
|
|
multicol. Using patches sent in by Edward Avis, Tidy now offers a
|
|
quiet mode which suppresses the initial welcome message and the
|
|
summary report on the number of errors or warnings. Jason
|
|
Tribbeck sent in patches to allow config options normally set in
|
|
the config file to be set on the command line, by preceding them
|
|
with a "--" (no intervening space), for example:</p>
|
|
|
|
<pre>
|
|
tidy --break-before-br true --show-warnings false
|
|
</pre>
|
|
|
|
<p>Kenichi Numata discovered that Tidy looped indefinitely for
|
|
examples similar to the following:</p>
|
|
|
|
<pre>
|
|
<font size=+2>Title
|
|
<ol>
|
|
</font>Text
|
|
</ol>
|
|
</pre>
|
|
|
|
<p>I have now cured this problem which used to occur when a
|
|
</font> tag was placed at the beginning of a list element.
|
|
If the example included a list item before the </ol> Tidy
|
|
will now create the following markup:</p>
|
|
|
|
<pre>
|
|
<font size=+2>Title</font>
|
|
<blockquote>Text </blockquote>
|
|
<ol>
|
|
<li>list item</li>
|
|
</ol>
|
|
</pre>
|
|
|
|
<p>This uses blockquote to indent the text without the
|
|
bullet/number and switches back to the ol list for the first true
|
|
list item.</p>
|
|
|
|
<p>I have worked hard to improve support for server side
|
|
preprocessing instructions such as ASP, PHP and Tango. Tidy now
|
|
allows you to replace attribute values by such instructions and
|
|
is able to fix up the case where the instruction appears without
|
|
delimiting quote marks. Tidy supports ASP and PHP in element
|
|
content and also in place of attribute value pairs. Support for
|
|
Tango is limited to attribute values only.</p>
|
|
|
|
<p>John Love-Jensen contribute a table for mapping the MacRoman
|
|
character set into Unicode. I have added a new charset option
|
|
"mac" to support this. Note the translation is one way and
|
|
doesn't convert back to the Mac codes on output.</p>
|
|
|
|
<p>Some people place <p> at the end of their list items to
|
|
introduce whitespace before the next item. I have modified
|
|
TrimEmptyElement to coerce empty p elements to br elements to
|
|
reproduce this rendering. If a p start tag is found in dt
|
|
elements, I now coerce the p to a br. Satwinder Mangat has
|
|
alerted me to several such problems. First, text as a direct
|
|
child of dl should be wrapped in a dt and not a dd element.
|
|
Second, unlike other inline tags, browser only close anchors on a
|
|
anchor start or end tag. Actually Navigator and IE differ in how
|
|
they handle this. Try the following example:</p>
|
|
|
|
<pre>
|
|
<p><b><a href=foo>some text</i> which should be in the label</a></p>
|
|
|
|
<p>next para and guess what the emphasis will be?</p>
|
|
</pre>
|
|
|
|
<p>Navigator 4 renders the second paragraph in normal text while
|
|
IE renders it in bold. If you substitute <a> for the
|
|
</i>, once again the browsers differ. IE stops underlining
|
|
at the <a> text while Navigator continues until the
|
|
</a>, although it realizes that you can't click there.</p>
|
|
|
|
<p>Satwinder continues: browsers happily interpret center within
|
|
a heading. Tidy now moves the center element to be the parent of
|
|
the rest of the heading, splitting it as needed, rather than
|
|
prematurely ending the heading. The same applies to a div element
|
|
within a heading. Satwinder notes that Tidy inserts a ul when an
|
|
li is encountered as a direct child of body.</p>
|
|
|
|
<p>This is a case where you can't produce a legal HTML file that
|
|
renders the same way as browsers handle this. The same applies to
|
|
a dt or dd element without an enclosing dl element. I can report
|
|
that W3C's HTML working group was unwilling to bless naked li's
|
|
etc. A similar problem arises for dt elements when they contain
|
|
hr, center or div. The specs say this is illegal, but browsers
|
|
render it fine!</p>
|
|
|
|
<p>I have done my best for hr, splitting the dt as needed and
|
|
enclosing the hr within a dd. The hr doesn't look the same,
|
|
sadly, as it now starts at the left margin for the dd'st rather
|
|
than the left margin for dt's. I wasn't sure how to deal with
|
|
center and div within dt, and chose to discard them.</p>
|
|
|
|
<p></br> is now mapped to <br> to match observed
|
|
browser rendering. On the same basis, an unmatched </p> is
|
|
mapped to <br><br>. This should improve fidelity of
|
|
tidied files to the original rendering, subject to the
|
|
limitations in the HTML standards described above.</p>
|
|
|
|
<p>Vlad Harchev spotted that Tidy was swallowing the first and
|
|
last spaces within inline elements when in a pre element. Now
|
|
fixed. Zac Thompson spotted that Tidy didn't know that the tags
|
|
s, strike and u weren't allowed in HTML4 strict. I have now fixed
|
|
this.</p>
|
|
|
|
<p>Tidy now preserves the last modified time for the files it
|
|
writes back to. This was introduced on the suggestion of
|
|
René Fritz, who uses the SiteCopy utility to upload recently
|
|
modified files to his Web server. By preserving file timestamps
|
|
Tidy can be used on all files in a directory without impacting
|
|
which ones will be uploaded, the next time SiteCopy runs. This is
|
|
implemented using the fstat and futime system calls. If your
|
|
platform doesn't support these calls, set PRESERVEFILETIMES to 0
|
|
in platform.h</p>
|
|
|
|
<p>I have fixed a bug on lexer.c which screwed up the removal of
|
|
doctype elements. This bug was associated with the symptom of
|
|
printing an indefinite number of doctype elements.</p>
|
|
|
|
<h2>August 1999</h2>
|
|
|
|
<p>Added lowsrc and bgproperties attributes to attribute table.
|
|
Rob Clark tells me that bgproperties="fixed" on the body elements
|
|
causes NS and IE to fix the background relative to the window
|
|
rather that the document's content.</p>
|
|
|
|
<p>Terry Teague kindly drew my attention to several bugs
|
|
discovered by other people: My thanks to Randy Waki for
|
|
discovering a bug when an unexpected inline end-tag is found in a
|
|
ul or ol element. I have added new code to ParseList in parser.c
|
|
to pop the inline stack and discard the end tag. I am checking to
|
|
see whether a similar problem occurs elsewhere. Randy also
|
|
discovered a bug (now fixed) in TrimInitialSpace() in parser.c
|
|
which caused it to fail when the element was the first in the
|
|
content. John Cumming found that comments cause problems in table
|
|
row group elements such as tbody. I have fixed this oversight in
|
|
this release.</p>
|
|
|
|
<p>Bjoern Hoehrmann tells me that bgsound is only allowed in the
|
|
head and not in the body, according to the Microsoft
|
|
documentation. I have therefore updated the entry in tags.c. The
|
|
slide generation feature caused an exception when the original
|
|
document didn't include a document type declaration. The fix
|
|
involve setting the link to the parent node when creating the
|
|
doctype node.</p>
|
|
|
|
<h2>26th July 1999</h2>
|
|
|
|
<p>Jussi Vestman reported a bug in FixDocType in lexer.c which
|
|
caused tidy to corrupt the parse tree, leading to an infinite
|
|
loop. I independently spotted this and fixed it. Justin
|
|
Farnsworth spotted that Tidy wasn't handling XML processing
|
|
instructions which end in ?> rather than just > as
|
|
specified by SGML. I have added a new option:
|
|
assume-xml-procins: yes which when set to yes expects the
|
|
XML style of processing instruction. It defaults to no, but is
|
|
automatically set to yes for XML input. Justin notes that the XML
|
|
PIs are used for a server preprocessor format called PHP, which
|
|
will now be easy to handle with Tidy. Richard Allsebrook's mail
|
|
prompted me to make sure that the contents of processing
|
|
instructions are treated as CDATA so that < and > etc. are
|
|
passed through unescaped.</p>
|
|
|
|
<p>Bill Sowers asks for Tidy to support another server
|
|
preprocessor format called Tango which features syntax such
|
|
as:</p>
|
|
|
|
<pre>
|
|
<b><@include <@cgi><appfilepath>includes/message.html></b>
|
|
</pre>
|
|
|
|
<p>I don't have time to add support for Tango in this release,
|
|
but would be happy if someone else were to mail in appropriate
|
|
changes. Darrell Bircsak reports problems when using DOS on
|
|
Win98. I am using Win95 and have been unable to reproduce the
|
|
problem. Jelks Cabaniss notes that Tidy doesn't support XML
|
|
document type subset declarations. This is a documented
|
|
shortcoming and needs to be fixed in the not too distant future.
|
|
Tidy focuses on HTML, so this hasn't been a priority todate.</p>
|
|
|
|
<p>Jussi Vestman asks for an optional feature for mapping IP
|
|
addresses to DNS hostnames and back again in URLs. Sadly, I don't
|
|
expect to be able to do this for quite a while. Adding network
|
|
support to Tidy would also allow it to check for bad URLs.</p>
|
|
|
|
<p>Ryan Youck reports that Tidy's behavior when finding a ul
|
|
element when it expects an li start tag doesn't match Netscape or
|
|
IE. I have confirmed this and have changed the code for parsing
|
|
lists to append misplaced lists to the end of the previous list
|
|
item. If a new list is found in place of the first list item, I
|
|
now place it into a blockquote and move it before the start of
|
|
the current list, so as to preserve the intended rendering.</p>
|
|
|
|
<p>I have added a new option - enclose-text which encloses any
|
|
text it finds at the body level within p elements. This is very
|
|
useful for curing problems with the margins when applying style
|
|
sheets.</p>
|
|
|
|
<h2>9th July 1999</h2>
|
|
|
|
<p>Added bgsound to tags.c. Added '_' to definition of namechars
|
|
to match html4.decl. My thanks to Craig Horman for spotting
|
|
this.</p>
|
|
|
|
<p>Jelks Cabaniss asked for the clean option to be automatically
|
|
set when the drop-font-tags option is set. Jelks also notes that
|
|
a lot of the authoring tools automatically generate, for example,
|
|
<I> and <B> in place of <em> and <strong>
|
|
(MS FrontPage 98 generated the latter, but FP2000 has reverted to
|
|
the former - with no option to change or set it). Jelks suggested
|
|
adding a general tag substitution mechanism. As a simpler measure
|
|
for now, I have added a new property called logical-emphasis to
|
|
the config file for replacing i by em and b by strong.</p>
|
|
|
|
<h2>7th July 1999</h2>
|
|
|
|
<p>Fixed recent bug with escaping ampersands and plugged memory
|
|
leaks following Terry Teagues suggestions. Changed
|
|
IsValidAttrName() in lexer.c to test for namechars to allow - and
|
|
: in names.</p>
|
|
|
|
<h2>2nd July 1999</h2>
|
|
|
|
<p>Chami noticed that the definition for the marquee tag was
|
|
wrong. I have fixed the entry in tags.c and Tidy now works fine
|
|
on the example he sent. To support mixing MathML with HTML I have
|
|
added a new config option for declaring empty inline tags
|
|
"new-empty-tags". Philip Riebold noted that single quote marks
|
|
were being silently dropped unless quote marks was set to yes.
|
|
This is an unfortunate bug recently introduced and now fixed.</p>
|
|
|
|
<p>Paul Smith sent in an example of badly formed tables, where
|
|
paragraph elements occurred in table rows without enclosing table
|
|
cells. Tidy was handling this by inserting a table cell. After
|
|
comparison with Netscape and IE, I have revised the code for
|
|
parsing table rows to move unexpected content to just before the
|
|
table.</p>
|
|
|
|
<h2>26th June 1999</h2>
|
|
|
|
<p>Tony Leneis reports that Tidy incorrectly thinks the table
|
|
frame attribute is a transitional feature. Now fixed. Chami
|
|
reported a bug in ParseIndent in config.c and that onsumbit is
|
|
missing from the table of attributes. Both now fixed. Carsten
|
|
Allefeld reports that Tidy doesn't know that the valign attribute
|
|
was introduced in HTML 3.2 and is ok in HTML 4.0 strict,
|
|
necessitating a trivial change to attrs.c.</p>
|
|
|
|
<p>Axel Kielhorn notes that Tidy wasn't checking the preamble for
|
|
the DOCTYPE tag matches either "html PUBLIC" or "html SYSTEM".
|
|
Bill Homer spotted changes needed for Tidy to compile with SGI
|
|
MIPSpro C++. All of Bill's changes have been incorporated, except
|
|
for the include file "unistd.h" (for the unlink call) which isn't
|
|
available on win32. To include this define NEEDS_UNISTD_H</p>
|
|
|
|
<p>Bjoern Hoehrmann asked for information on how to use the
|
|
result returned by Tidy when it exits. I have included a example
|
|
using Perl that Bjoern sent in. Bodo Eing reported that Tidy gave
|
|
misleading warning when title text is emphasized. It now reports
|
|
a missing </title> before any unexpected markup.</p>
|
|
|
|
<p>Bruce Aron says that many WYSIWYG HTML editors place a font
|
|
element around an hypertext link enclosing the anchor element
|
|
rather that its contents. Unfortunately, the anchor element then
|
|
overrides the color change specified by the font element! I have
|
|
added an extra rule to ParseInline to move the font element
|
|
inside an anchor when the anchor is the only child of the font
|
|
element. Note CSS is a better long term solution, and Tidy can be
|
|
used to replace font elements by style rules using the clean
|
|
option.</p>
|
|
|
|
<p>Carsten Allefeld reported that valign on table cells caused
|
|
Tidy to mislabel content as HTML 4.0 transitional rather than
|
|
strict. Now fixed. A number of people said they expected the
|
|
quote-mark option to apply to all text and not just to attribute
|
|
values. I have obliged and changed the option accordingly.</p>
|
|
|
|
<p>Some people have wondered why "</" causes an error when
|
|
present within scripts. The reason is that this substring is not
|
|
permitted by the SGML and XML standards. Tidy now fixes this by
|
|
inserting a backslash, changing the substring to "<\/". Note
|
|
this is only done for JavaScript and not for other scripting
|
|
languages.</p>
|
|
|
|
<p>Chami reported that onsubmit wasn't recognized by Tidy - now
|
|
fixed. Chris Nappin drew my attention to the fact that script
|
|
string literals in attributes weren't being wrapped correctly
|
|
when QuoteMarks was set to no. Now fixed. Christian Zuckschwerdt
|
|
asked for support for the POSIX long options format e.g. --help.
|
|
I have modified tidy.c to support this for all the long options.
|
|
I have kept support for -help and -clean etc.</p>
|
|
|
|
<p>Craig Horman sent in a routine for checking attribute names
|
|
don't contain invalid characters, such as commas. I have used
|
|
this to avoid spurious attribute/value pairs when a quotemark is
|
|
misplaced. Darren Forcier is interested in wrapping Tidy up as a
|
|
Win32 DLL. Darren asked for Tidy to release its memory resources
|
|
for the various tables on exit. Now done, see DeInitTidy() in
|
|
tidy.c</p>
|
|
|
|
<p>Darren also asks about the config file mechanism for declaring
|
|
additional tags, e.g. <b>new-blocklevel-tags: cfoutput,
|
|
cfquery</b> for use with Cold Fusion. You can add inline and
|
|
blocklevel elements but as yet you can't add empty elements
|
|
(similar to br or hr) or to change the content model for the
|
|
table, ul, ol and dl elements. Note that the indent option
|
|
applies to new elements in the same way as it does for built-in
|
|
elements. Tidy will accept the following:</p>
|
|
|
|
<pre>
|
|
<cfquery name="MyQuery" datasource="Customer">
|
|
select CustomerName from foo where x > 1
|
|
</cfquery>
|
|
|
|
<cfoutput query="MyQuery">
|
|
<table>
|
|
<tr>
|
|
<td>#CustomerName#</TD>
|
|
</tr>
|
|
</table>
|
|
</cfoutput>
|
|
</pre>
|
|
|
|
<p>but the next example <b>won't</b> since you can't as yet
|
|
modify the content model for the table element:</p>
|
|
|
|
<pre>
|
|
<cfquery name="MyQuery" datasource="Customer">
|
|
select CustomerName from foo where x > 1
|
|
</cfquery>
|
|
|
|
<table>
|
|
<cfoutput query="MyQuery">
|
|
<tr>
|
|
<td>#CustomerName#</TD>
|
|
</tr>
|
|
</cfoutput>
|
|
</table>
|
|
</pre>
|
|
|
|
<p>I have been studying richer ways to support modular extensions
|
|
to html using assertions and a generalization of regular
|
|
expressions to trees. This work has led a tool for generating
|
|
DTDs named <b>dtdgen</b> and I am in the process of creating a
|
|
further tool for verification. More information is available in
|
|
my note on <a
|
|
href="http://www.w3.org/People/Raggett/dtdgen/Docs">Assertion
|
|
Grammars</a>. Please contact me if you are interested in helping
|
|
with this work.</p>
|
|
|
|
<p>David Fallon is interested in using Tidy to dynamically repair
|
|
markup in an HTML editor as people type. My recommendation is to
|
|
take advantage of the tables in tags.c and attrs.c for this, and
|
|
to defer to application of the full range of heuristics to such a
|
|
time as saving to disk or when explicitly requested. The CM_OPT
|
|
property in the tags table indicates that the end tag is
|
|
optional, while CM_EMPTY indicates that an element is
|
|
<i>empty</i>, i.e. has no content.</p>
|
|
|
|
<p>Betsy Miller reports: <i>I tried printing the HTML Tidy page
|
|
for a class I am teaching tomorrow on HTML, and everything in the
|
|
"green" style (all of the examples) print in the smallest font I
|
|
have ever seen (in fact they look like tiny little horizontal
|
|
lines). Any explanation?</i>.</p>
|
|
|
|
<p>Yes. This is a problem with Internet Explorer and Style
|
|
Sheets. The Tidy page includes a CSS style sheet that tries to
|
|
make the size of the font used for the examples 80% smaller than
|
|
for normal text. Internet Explorer gets this wrong, picking a
|
|
very much smaller font. I am hoping this bug is fixed in the IE
|
|
5.0 release. I have changed the style sheet to work around
|
|
this.</p>
|
|
|
|
<p>Francisco Guardiola writes that Tidy wasn't fixing frameset
|
|
documents with body elements unenclosed in noframes elements. Now
|
|
fixed. Frederik Fouvry found that comments after the html end tag
|
|
generated a warning for content after body. I can't reproduce
|
|
this symptom and assume it was fixed in an earlier release.</p>
|
|
|
|
<p>Indrek Toom wants to know how to format tables so that tr
|
|
elements indent their content, but td tags do not. The solution
|
|
is to use <i>indent: auto</i>. Jelks Cabaniss noted that the
|
|
clean option created style rules with tag names in uppercase,
|
|
which would cause problems for Extensible HTML (xhtml). This
|
|
prompted me to overhaul Tidy to switch to lower case for that tag
|
|
tables and literals. I have adopted Jelks' suggestion for adding
|
|
support for a doctype property in config files. This supports
|
|
<em>omit, auto, strict, loose</em> or a string specifying the fpi
|
|
(formal public identifier).</p>
|
|
|
|
<p>Johannes Koch notes that Tidy doesn't fix up the doctype
|
|
correctly when bursting to slides. He says that if a document
|
|
contains the HTML 4.0 strict DT declaration, then the slides also
|
|
include the same strict DT declaration, but also contain the
|
|
center tag which does not appear in the strict DTD. I have
|
|
applied a simple work around, which is to remove the original
|
|
doctype when bursting to slides.</p>
|
|
|
|
<p>I have extended the support for the ASP preprocessing syntax
|
|
to cope with the use of ASP within tags for attributes. I have
|
|
also added a new option <tt>wrap-asp</tt> to the config file
|
|
support to allow you to turn off wrapping within ASP code. Thanks
|
|
to Ken Cox for this idea.</p>
|
|
|
|
<p>Larry Virden asked for a compile-time option for setting the
|
|
config file, he says "The reason it would be useful is to be able
|
|
to define a set of commonly used additional tags. For instance,
|
|
our site is starting to use a lot of ColdFusion. I would love to
|
|
be able to put the CF tags into a site wide file so that users of
|
|
tidy automatically get them defined". You can now do this by
|
|
defining CONFIG_FILE in platform.h</p>
|
|
|
|
<p>Loïc Trégan asks: Is there a way to generate a
|
|
"light" xml, with no "<!DOCTYPE...>" and "xlmns=..."? I
|
|
have tweaked the code to allow the doctype property to apply when
|
|
outputting XML, and added a new property "add-xml-pi" to control
|
|
whether an <?xml?> processing instruction is added or not.
|
|
To generate a minimal XML document, you can set the xml-out
|
|
property to yes, the doctype and add-xml-pi property to no.</p>
|
|
|
|
<p>Marc Jauvin has been using Windows Application to generate Web
|
|
pages and found that some of them generate very "non-portable"
|
|
HTML. One of the problems that is often introduced is the use of
|
|
"\" in URLs instead of "/" which confuses Unix Web servers. To
|
|
deal with this I have introduced the "fix-backslash" property.
|
|
This has been set by default to yes, but can be set to no if that
|
|
causes problems.</p>
|
|
|
|
<p>The new property <tt>indent-attributes</tt> when set to yes
|
|
places each attribute on a new line. Note that the attributes are
|
|
only indented one space. Paul Ossenbruggen asked for something
|
|
slightly different, where the second and subsequent attributes
|
|
start on a new line and are indented to line up under the first
|
|
attribute. That proved to involve rather more work to implement
|
|
than I have time for right now. I plan to work some more on this
|
|
for a future release.</p>
|
|
|
|
<p>Peter Jeremy reported that when an error file is specified to
|
|
tidy (-f file), the error file is opened for every HTML file
|
|
specified on the command line, but not closed until all HTML
|
|
files have been processed. If a large number of files are
|
|
specified on the command line (e.g. processing the FreeBSD
|
|
handbook), this can overflow the process or system file
|
|
descriptor table. I have now fixed this so that the error file is
|
|
only opened once.</p>
|
|
|
|
<p>Rafi Stern notes: I have entered output-xml: yes in my config
|
|
file, not output-xhtml. Tidy second guesses me and adds the xmlns
|
|
attribute for XHTML at the head of my file, which I then have to
|
|
remove as this interferes with my XSLT parser. Fixed along with
|
|
the other bugs reported by Rafi.</p>
|
|
|
|
<p>Steffen Ullrich and Andy Quick both spotted a problem with
|
|
attribute values consisting of an empty string, e.g.
|
|
<tt>alt=""</tt>. This was caused by bugs in tidy.c and in
|
|
lexer.c, both now fixed. Jussi Vestman noted Tidy had problems
|
|
with hr elements within headings. This appears to be an old bug
|
|
that came back to life! Now fixed. Jussi also asked for a config
|
|
file option for fixing URLs where non-conforming tools have used
|
|
backslash instead of forward slash.</p>
|
|
|
|
<p>An example from Thomas Wolff allowed me to the idea of
|
|
inserting the appropriate container elements for naked list items
|
|
when these appear in block level elements. At the same time I
|
|
have fixed a bug in the table code to infer implicit table rows
|
|
for text occurring within row group elements such as thead and
|
|
tbody. An example sent in by Steve Lee allowed me to pin point an
|
|
endless loop when a head or body element is unexpectedly found in
|
|
a table cell.</p>
|
|
|
|
<h2>15th April 1999</h2>
|
|
|
|
<p>Another minor release. Jacob Sparre Andersen reports a bug
|
|
with &quot; in attribute values. Now fixed. Francisco
|
|
Guardiola reports problems when a body element follows the
|
|
frameset end tag. I have fixed this with a patch to ParseHTML,
|
|
ParseNoFrames and ParseFrameset in parser.c Chris Nappin wrote in
|
|
with the suggestion for a config file option for enabling
|
|
wrapping script attributes within embedded string literals. You
|
|
can now do this using "wrap-script-strings: yes".</p>
|
|
|
|
<h2>14th April 1999</h2>
|
|
|
|
<p>Added check for Asp tags on line 2674 in parser.c so that Asp
|
|
tags are not forcibly moved inside an HTML element. My thanks to
|
|
Stuart Updegrave for this. Fixed problem with & entities.
|
|
Bede McCall spotted that &amp; was being written out as
|
|
&amp;amp;. The fix alters ParseEntity() in lexer.c</p>
|
|
|
|
<h2>12th April 1999</h2>
|
|
|
|
<p>Added a missing "else" on line 241 in config.c (thanks for
|
|
Keith Blakemore-Noble for spotting this). Added config.c and .o
|
|
to the Makefile (an oversight in the release on the 8th
|
|
April).</p>
|

<h2>8th April 1999</h2>

<h4>Localization:</h4>
|
|
|
|
<p>All the message text is now defined in localize.c which should
|
|
make it a tad easier to localize Tidy for different
|
|
languages.</p>
|
|
|
|
<h4>Config file support:</h4>
|
|
|
|
<p>I have added support for configuring tidy via a configuration
|
|
file. The new code is in config.h which provides a table driven
|
|
parser for RFC822 style headers. The new command line option
|
|
-config <filename> can be used to identify the config file.
|
|
The environment variable "HTML_TIDY" may be used to name the
|
|
config file. If defined, it is parsed before scanning the command
|
|
line. You are advised to use an absolute path for the variable to
|
|
avoid problems when running tidy in different directories.</p>
|
|
|
|
<h4>Allan Kuchinsky:</h4>
|
|
|
|
<p>Reports that the XML DOM parser by Eduard Derksen screws up on
|
|
 , naked & and % in URLs as well as having problems with
|
|
newlines after the '=' before attribute values.</p>
|
|
|
|
<p>I have tweaked PrintChar when generating XML to output  
|
|
in place of &nbsp; and &amp; in place of &. In
|
|
general XHTML when parsed as well-formed XML shouldn't use named
|
|
entities other than those defined in XML 1.0. Note that this
|
|
isn't a problem if the parser uses the XHTML DTDs which import
|
|
the entity definitions.</p>
|
|
|
|
<h4>Allan Odgaard:</h4>
|
|
|
|
<p>When tidy encounter entities without a terminating semi-colon
|
|
(e.g. "©") then it correctly outputs "©", but it
|
|
doesn't report an error.</p>
|
|
|
|
<p>I have added a ReportEntityError procedure to localize.c and
|
|
updated ParseEntity to call this for missing semicolons and
|
|
unknown entities.</p>
|
|
|
|
<h4>Andreas Buchholz:</h4>
|
|
|
|
<p>Tidy warns if table element is missing. This is incorrect for
|
|
HTML 3.2 which doesn't define this attribute.</p>
|
|
|
|
<p>The summary attribute was introduced in HTML 4.0 as an aid for
|
|
accessibility. I have modified CheckTABLE to suppress the warning
|
|
when the document type explicitly designates the document as
|
|
being HTML 2.0 or HTML 3.2.</p>
|
|
|
|
<h4>Andy Brown:</h4>
|
|
|
|
<p>I have renamed the field from class to tag_class as "class" is
|
|
a reserved word in C++ with the goal of allowing tidy to be
|
|
compiled as C++ e.g. when part of a larger program.</p>
|
|
|
|
<p>I have switched to Bool and the values yes and no to avoid
|
|
problems with detecting which compilers define bool and those
|
|
that don't.</p>
|
|
|
|
<p>Andy would prefer a return code or C++ exception rather than
|
|
an exit. I have removed the calls to exit from pprint.c and used
|
|
a long jump from FatalError() back to main() followed by
|
|
returning 2. It should be easy to adapt this to generate a C++
|
|
exception.</p>
|
|
|
|
<p>Sometimes the prev links are inconsistent with next links. I
|
|
have fixed some tree operations which might have caused this. Let
|
|
me know if any inconsistencies remain.</p>
|
|
|
|
<h4>Ann Navarro:</h4>
|
|
|
|
<p>Would like to be able to use:</p>
|
|
|
|
<pre>
|
|
tidy file.html | more
|
|
</pre>
|
|
|
|
<p>to pause the screen output, and/or full output passing to file
|
|
as with</p>
|
|
|
|
<pre>
|
|
tidy file.html > output.txt
|
|
</pre>
|
|
|
|
<p>Tidy writes markup to stdout and errors to stderr. 'More' only
|
|
works for stdout so that the errors fly by. My compromise is to
|
|
write errors to stdout when the markup is suppressed using the
|
|
command line option -e or "markup: no" in the config file.</p>
|
|
|
|
<h4>html-kit@chamisplace.com</h4>
|
|
|
|
<p>Writes asking for a single output routine for Tidy. Acting on
|
|
his suggestion, I have added a new routine tidy_out() which
|
|
should make it easier to embed HTML Tidy in a GUI application
|
|
such as HTML-Kit. The new routine is in localize.c. All input
|
|
takes place via ReadCharFromStream() in tidy.c, excepting command
|
|
line arguments and the new config file mechanism.</p>
|
|
|
|
<p>Chami also asks for single routines for initializing and
|
|
de-initializing Tidy, something that happens often from the GUI
|
|
environment of HTML-Kit. I have added InitTidy() and DeInitTidy()
|
|
in tidy.c to try to satisfy this need. Chami now supports an
|
|
online interface for Tidy at the URL:</p>
|
|
|
|
<pre>
|
|
<a
|
|
href="http://www.chamisplace.com/asp/hk.asp">http://www.chamisplace.com/asp/hk.asp</a>
|
|
</pre>
|
|
|
|
<p>He further asks for Tidy to optionally output a length
|
|
parameter whenever possible. This could represent the length of
|
|
the element, attribute or code block related to the error. An
|
|
online validator could then highlight the starting and ending
|
|
columns which may be easier for beginners to understand, rather
|
|
than pointing to a single character column. I will investigate
|
|
this for a future release.</p>
|
|
|
|
<h4>Chang Hyun Baek:</h4>
|
|
|
|
<p>Reports a problem when generating XML using -iso2022. Tidy
|
|
inserts ?/p< rather than </p>. I tried Chang's test file
|
|
but it worked fine with in all the right places. Please let me
|
|
know if this problem persists.</p>
|
|
|
|
<h4>Christian Ruetgers:</h4>
|
|
|
|
<p>When using -indent option Tidy emits a newline before which
|
|
alters the layout of some tables.</p>
|
|
|
|
<p>I note that browsers aren't conforming to the SGML spec on
|
|
generally ignoring a newline immediately after start tags and
|
|
immediately before end tags. Netscape does this for pre elements
|
|
but not for other tags! My work around is to avoid additional
|
|
newlines for the content of th and td elements, except where
|
|
their content starts with a block level element. This kind of
|
|
thing is getting really hairy!</p>
|
|
|
|
<h4>Christian Pantel:</h4>
|
|
|
|
<p>Would like the servlet tag added to tidy. This looks very
|
|
similar to applet and used for preprocessing document content
|
|
before delivery. Servlet acts as a container for param elements
|
|
and fallback content to be shown if the server doesn't support
|
|
servlet. I have added it as a proprietary tag and parse it in the
|
|
same way as applet.</p>
|
|
|
|
<p>Christian also reports that <td><hr/></td>
|
|
caused Tidy to discard the <hr/> element. I have fixed the
|
|
associated bug in ParseBlock.</p>
|
|
|
|
<h4>Chuck Baslock:</h4>
|
|
|
|
<p>Points out that an isolated & is converted to & in
|
|
element content and in attribute values. This is in fact correct
|
|
and in agreement with the recommendations for HTML 2.0
|
|
onwards.</p>
|
|
|
|
<h4>Craig Horman:</h4>
|
|
|
|
<p>Reports that Tidy loops indefinitely if a naked LI is found in
|
|
a table cell. I have patched ParseBlock to fix this, and now
|
|
successfully deal with naked list items appearing in table cells,
|
|
clothing them in a ul.</p>
|
|
|
|
<h4>Craig Johnson:</h4>
|
|
|
|
<p>Reports that Tidy gets confused by </comment> before the
|
|
doctype. This is apparently inserted by some authoring tool or
|
|
other. I have patched Tidy to safely recover from the
|
|
unrecognized and unexpected end tag without moving the parse
|
|
state into the head or body.</p>
|
|
|
|
<h4>Daniel Vogelheim:</h4>
|
|
|
|
<p>Asks for Tidy to recognize obsolete elements such as LISTING
|
|
and to replace them by more modern equivalents, in this case pre.
|
|
I have added code to issue a warning and replace such elements as
|
|
xmp, listing, plaintext by pre, and dir and menu by ul. Daniel
|
|
also asks for a means to suppressing warnings, i.e. to only
|
|
report errors. I have added the boolean "show-warnings" to the
|
|
config file support to deal with this and split off warnings to
|
|
ReportWarnings().</p>
|
|
|
|
<h4>Dan Rudman:</h4>
|
|
|
|
<p>Would love a version of Tidy written in Java. This is a big
|
|
job. I am working on a completely new implementation of Tidy,
|
|
this time using an object-oriented approach but I don't expect to
|
|
have this done until later this year. <b>DEFERRED</b></p>
|
|
|
|
<h4>David Brooke:</h4>
|
|
|
|
<p>Reports that when tidying an XMLfile with characters above 127
|
|
Tidy is outputting the numeric entity followed by the character.
|
|
I have fixed this by a patch to PPrintChar() for XmlTags.</p>
|
|

<h4>David Getchell:</h4>
|
|
|
|
<p>Reports that Tidy thinks an ol list is HTML 4.0 when you use
|
|
the type attribute. I have fixed an error in attrs.c to correct
|
|
this feature to first appearing in HTML 3.2.</p>
|
|
|
|
<h4>Drew Adams:</h4>
|
|
|
|
<p>Reported problems when using comments to hide the contents of
|
|
script elements from ancient browsers. I wasn't able to reproduce
|
|
the problem, and guess I fixed it earlier.</p>
|
|
|
|
<p>Drew also reported a problem which on further investigation is
|
|
caused by the very weird syntax for comments in SGML and XML. The
|
|
syntax for comments is really error prone:</p>
|
|
|
|
<pre>
|
|
<!--[text excluding --]--[[whitespace]*--[text excluding --]--]*>
|
|
</pre>
|
|
|
|
<p>This means that <!----> is a complete comment but
|
|
<!------> is not since the parser is expecting a matching
|
|
terminating -- and as it doesn't find the -- it ploughs on and on
|
|
treating the rest of the markup as a comment unless it finds
|
|
another end comment. I have added a rule of thumb (a heuristic)
|
|
for detecting this situation. Basically I count the number of
|
|
comment groups without other characters and if the count is >
|
|
2 and a '>' is seen, a warning is generated.</p>
|
|
|
|
<p>Drew goes on to comment on the -clean option. This made me
|
|
take another look at the relative font sizes I am using for the
|
|
absolute font sizes for 0 through 6. I have tweaked them to get a
|
|
reasonable match before/after applying -clean as viewed on NS4
|
|
and IE4. Font size=3 is taken as the normal body font size and as
|
|
such the font element is silently dropped unless it also defines
|
|
a color.</p>
|
|
|
|
<p>I have also added InlineStyle to deal with the cases where an
|
|
inline element has as its only child a font element. A further
|
|
possibility would be to promote style properties common to all
|
|
children of an element to the element. I will have to leave this
|
|
for future work.</p>
|
|
|
|
<p>Drew asks why </ is not allowed in script content. The
|
|
answer is that SGML treats </ as delimiting the end of CDATA
|
|
element content, so that it ends prematurely before the
|
|
</script> end tag. Browsers tend not to follow the SGML
|
|
standard in this respect, but Tidy is designed to help you do
|
|
so.</p>
|

|
<h4>Guus Goos:</h4>
|
|
|
|
<p>Notes that tidy *.html doesn't work under DOS. This is because
|
|
DOS unlike Unix doesn't expand names with wildcards to the list
|
|
of matching file names. This is a right nuisance and one more
|
|
reason why Linux is gaining popularity. I plan to provide a work
|
|
around in a future release of Tidy. Are there any free drop-in
|
|
replacements for the DOS shell that fix this problem?</p>
|
|
|
|
<h4>Jack Horsfield:</h4>
|
|
|
|
<p>Like a number of others would like list items and table cells
|
|
to be output compactly where possible. I have added a flag to
|
|
avoid indentation of content to tags.c that avoids further
|
|
indentation when the content is inline, e.g.</p>
|
|
|
|
<pre>
|
|
<ul>
|
|
<li>some text</li>
|
|
<li>
|
|
<p>
|
|
a new paragraph
|
|
</p>
|
|
</li>
|
|
</ul>
|
|
</pre>
|
|
|
|
<p>This behavior is enabled via "smart-indent: yes" and overrides
|
|
"indent: no". Use "indent-spaces: 5" to set the number of spaces
|
|
used for each level of indentation.</p>
|
|
|
|
<h4>Jeff Young:</h4>
|
|
|
|
<p>Has a few suggestions that will make Tidy work with XSL.
|
|
Thanks, I have incorporated all of them into the new release.</p>
|
|
|
|
<h4>Jelks Cabaniss:</h4>
|
|
|
|
<p>Reports that the Tidy thinks the end tag is missing if the
|
|
script element has no content. I have patched ParseScript to fix
|
|
this. Jelks also asks for a way to ask Tidy to hide the contents
|
|
of script and style elements; a way to avoid promoting inline
|
|
styles with -clean to style rules as a work around for a bug in
|
|
IE for URLs with relative URLs; finally, a way to avoid empty
|
|
elements being discarded, especially if they define an ID for
|
|
scripting. Very reasonable, but I would prefer leave these to a
|
|
future release. (This release is big enough right now!).</p>
|
|
|
|
<p>One thing I can satisfy right away is a mailing list for Tidy.
|
|
html-tidy@w3.org has been created for discussing Tidy and I have
|
|
placed the details for subscribing and accessing the Web archive
|
|
on the Tidy overview page.</p>
|
|
|
|
<h4>Johannes Koch:</h4>
|
|
|
|
<p>Reports that Tidy isn't quite right about when it reports the
|
|
doctype as inconsistent or not. I have tweaked HTMLVersion() to
|
|
fix this. Let me know if any further problems arise.</p>
|
|
|
|
<h4>John Tobler:</h4>
|
|
|
|
<p>Wants to know how to get Tidy to preserve his explicit
|
|
entities e.g. " and  . Currently Tidy interprets all
|
|
entities as character values and as such has no way to
|
|
distinguish whether these were derived from entities or not. To
|
|
help John with this release you can use "quote-marks: yes" in the
|
|
config file if you want all " marks to appear as " and
|
|
"quote-nbsp: yes" if you want non-breaking spaces to be shown as
|
|
entities. Note that for XML in general   is not-predeclared,
|
|
so you should also use "numeric-entities: yes". This doesn't
|
|
apply to XHTML though.</p>
|
|
|
|
<p>John also reports that the weirdly complex URLs using the
|
|
javascript: scheme as used by www.bookmarklets.com can cause Tidy
|
|
indigestion. I have made Tidy aware of which attributes are using
|
|
Javascript and disabled the missing quote mark heuristic for
|
|
these. I have also tweaked the way unknown entities are reported
|
|
to say that the markup have contain unescaped ampersands.</p>
|
|
|
|
<h4>Mathew Cepl:</h4>
|
|
|
|
<p>Notes that dir and menu are deprecated and not allowed in
|
|
HTML4 strict. I have updated the entry in the tags table for
|
|
these two. I also now coerce them automatically to ul when -clean
|
|
is set.</p>
|
|
|
|
<h4>Maurice Buxton:</h4>
|
|
|
|
<p>Reports that some implementations of gcc don't work with the
|
|
current compiler directive Tidy uses to avoid duplicate typedefs
|
|
for uint and ulong. I don't have a truly platform independent
|
|
solution for this, so you may need to edit platform.h if the code
|
|
doesn't compile out of the box on your platform.</p>
|
|
|
|
<h4>Osma Ahvenlampi:</h4>
|
|
|
|
<p>Found that Tidy is confused by map elements in the head. Tidy
|
|
knows that map is only allowed in the body and thinks the author
|
|
has left out the</p>
|
|
|
|
<p>start tag. Thereafter elements which it knows only belong in
|
|
the head are moved to the head, so things should work out ok.
|
|
Osma also reports having difficulties with non-breaking spaces,
|
|
but I was unable to reproduce these with the new release of Tidy,
|
|
so perhaps the problems have been fixed.</p>
|
|
|
|
<h4>Paul Ward:</h4>
|
|
|
|
<p>Reports that Tidy caused JavaScript errors when it introduced
|
|
linebreaks in JavaScript attributes. Tidy goes to some efforts to
|
|
avoid this and I am interested in any reports of further problems
|
|
with the new release.</p>
|
|
|
|
<h4>Rafi Stern:</h4>
|
|
|
|
<p>Would like Tidy to warn when a tag has an extra quote mark, as
|
|
in <a href="xxxxxx"">. I have patched ParseAttribute to do
|
|
this.</p>
|
|
|
|
<h4>Rene Fritz:</h4>
|
|
|
|
<p>Reported a space being inserted at the end of lines when a the
|
|
text is wrapped at the start of hypertext links. This isn't
|
|
occurring with this release, so I guess the problem was solved a
|
|
while back. Rene also suggests that Tidy could be used to add and
|
|
remove metadata and attributes etc. for a group of files, e.g. to
|
|
add a link to a style sheet or to assert attribution. This sounds
|
|
like a good idea for work in the future.</p>
|
|
|
|
<h4>Shane McCarron:</h4>
|
|
|
|
<p>Reports that Tidy sometimes wraps text within markup that
|
|
occurs in the context of a pre element. I am only able to repeat
|
|
this when the markup wraps within start tags, e.g. between
|
|
attribute values. This is perfectly legitimate and doesn't effect
|
|
rendering.</p>
|
|
|
|
<h4>Steven Lobo:</h4>
|
|
|
|
<p>Notes that Tidy doesn't remove entities such as &nbsp; or
|
|
&copy; which aren't defined by XML 1.0. That is true - these
|
|
entities <b>are</b> fine if you are using XHTML. If you want to
|
|
generate generic XML then you need to use the -n option or to set
|
|
"numeric-entities: yes" in the config file. This will then output
|
|
all such entities in their numeric form or as direct character
|
|
values according to the character encoding flags.</p>
|
|
|
|
<h4>Steven Pemberton:</h4>
|
|
|
|
<p>Comments that he would like Tidy to replace naked & in
|
|
URLs by &. You can now use "quote-ampersands: yes" in the
|
|
config file to ensure this. Note that this is always done when
|
|
outputting to XML where naked '&' characters are illegal.</p>
|
|
|
|
<p>Steven also asks for a way to allow Tidy to proceed after
|
|
finding unknown elements. The issue is how to parse them, e.g. to
|
|
treat them as inline or block level elements? The latter would
|
|
terminate the current paragraph whereas the former would not.</p>
|
|
|
|
<p>If treated as inline, presumably, unknown tags should be
|
|
treated specially, for instance, normal inline end tags close the
|
|
currently open inline element, but this doesn't feel right for
|
|
unknown tags. What should the content model for unknown tags be -
|
|
flow? Again its far from obvious. One way to avoid these
|
|
difficulties would be to provide a means for authors to declare
|
|
unknown tags in the config file.</p>
|
|
|
|
<p>You can now declare new inline and block-level tags in the
|
|
config file, e.g.:</p>
|
|
|
|
<pre>
|
|
define-inline-tags: foo, bar
|
|
define-blocklevel-tags: blob
|
|
</pre>
|
|
|
|
<p>The content model for new tags allows for block or inline
|
|
content. Steven further comments that some authors use ul without
|
|
an li to indent content. Tidy currently coerces these to wrap the
|
|
content within an li which alters the rendering. He suggests
|
|
using blockquote instead. I have done this, and if you use the
|
|
-clean option at the same time, it gets replaced by a div element
|
|
with a class and style rule for indenting the content.</p>
|
|
|
|
<h4>Stuart Updegrave:</h4>
|
|
|
|
<p>Would like to be able to coerce attributes to uppercase. I
|
|
have added support for "uppercase-attributes: yes" for this.
|
|
Stuart also asks for Tidy to support Microsoft's ASP tags. These
|
|
are part of Microsoft's server-side scripting model (similar to
|
|
CGI). I have treated ASP tags in the same way as processing
|
|
instructions, and they don't effect the version of HTML as they
|
|
are assumed to have been interpreted before delivery to the
|
|
client.</p>
|
|
|
|
<p>Stuart is also interested in having Tidy reading from and
|
|
writing back to the Windows clipboard. This sounds interesting
|
|
but I have to leave this to a future release.</p>
|
|
|
|
<h4>Terry Cassidy:</h4>
|
|
|
|
<p>Points out that Tidy doesn't like "top" or "bottom" for the
|
|
align attribute on the caption element. I have added a new
|
|
routine to check the align attribute for the caption element and
|
|
cleaned up the code for checking the document type.</p>
|
|
|
|
<h4>Xavier Plantefeve:</h4>
|
|
|
|
<p>Suggests that I should ensure that the options are self
|
|
consistent, e.g. if -asxml is set, then this should imply lower
|
|
case and override any instruction to omit optional end tags.
|
|
Accordingly, I have introduced a new routine AdjustConfig() that
|
|
is applied after reading the command line and config files and
|
|
before tidying any files.</p>
|
|
|
|
<p>Xavier wonders whether name attributes should be replaced or
|
|
supplemented by id attributes when translating HTML anchors to
|
|
XHTML. This is something I am thinking about for a future release
|
|
along with supplementing lang attributes by xml:lang
|
|
attributes.</p>
|
|
|
|
<h4>Zdenek Kabelac:</h4>
|
|
|
|
<p>Asks for headings and paragraphs to be treated specially when
|
|
other tags are indented. I have dealt with this via the new
|
|
smart-indent mechanism.</p>
|
|
|
|
<h2>22nd February 1999</h2>
|
|
|
|
<p>Tidy can now fix up XML empty tags for which the attribute
|
|
values are unquoted, e.g. <br clear=all/>. Care is taken to
|
|
avoid this being applied to tags with URLs, e.g. <a
|
|
href=http://acme.com/> where the / is part of the attribute
|
|
value and doesn't signify an empty tag. Authors are advised to
|
|
always quote attribute values to avoid such problems!</p>
|
|
|
|
<h2>22nd January 1999</h2>
|
|
|
|
<p>Tidy no longer complains about a missing </tr> before a
|
|
<tbody>. Added link to a free <a
|
|
href="http://www.chami.com/free/html-kit/">win32 GUI for
|
|
tidy</a>.</p>
|
|
|
|
<h2>11th January 1999</h2>
|
|
|
|
<p>Added a link to the OS/2 distribution of Tidy made available
|
|
by Kaz SHiMZ. No changes to Tidy's source code.</p>
|
|
|
|
<h2>7th January 1999</h2>
|
|
|
|
<p>Fixed bug in ParseBlock that resulted in nested table
|
|
cells.</p>
|
|
|
|
<p>Fixed clean.c to add the style property "text-align:" rather
|
|
than "align:".</p>
|
|
|
|
<p>Disabled line wrapping within HTML alt, content and value
|
|
attribute values. Wrapping will still occur when output as
|
|
XML.</p>
|
|
|
|
<h2>16th December 1998</h2>
|
|
|
|
<p>This release fixes a problem with missing quotemarks in
|
|
attribute values introduced in the December 14th release. It also
|
|
fixes problems with parsing tables when the table cells include
|
|
naked list items and when unexpected end tags are encountered for
|
|
td and tr cells. Warnings are now generated for unknown entities
|
|
(those not defined by HTML 4.0). It may be worth thinking about a
|
|
new option to determine how to handle these, especially for
|
|
XML.</p>
|
|
|
|
<h2>14th December 1998</h2>
|
|
|
|
<p>Rewrote parser for elements with CDATA content to fix problems
|
|
with tags in script content.</p>
|
|
|
|
<p>New pretty printer for XML mode. I have also modified the XML
|
|
parser to recognize xml:space attributes appropriately. I have
|
|
yet to add support for CDATA marked sections though.</p>
|
|
|
|
<p>script and noscript are now allowed in inline content.</p>
|
|
|
|
<p>To make it easier to drive tidy from scripts, it now returns 2
|
|
if any errors are found, 1 if any warnings are found, otherwise
|
|
it returns 0. Note tidy doesn't generate the cleaned up markup if
|
|
it finds errors other than warnings.</p>
|
|
|
|
<p>Fixed bug causing the column to be reported incorrectly when
|
|
there are inline tags early on the same line.</p>
|
|
|
|
<p>Added -numeric option to force character entities to be
|
|
written as numeric rather than as named character entities.
|
|
Hexadecimal character entities are never generated since Netscape
|
|
4 doesn't support them.</p>
|
|
|
|
<p>Entities which aren't part of HTML 4.0 are now passed through
|
|
unchanged, e.g. &precompiler-entity; This means that an
|
|
isolated & will be pass through unchanged since there is no
|
|
way to distinguish this from an unknown entity.</p>
|
|
|
|
<p>Tidy now detects malformed comments, where something other
|
|
than whitespace or '--' is found when '>' is expected at the
|
|
end of a comment.</p>
|
|
|
|
<p>The <br> tags are now positioned at the start of a blank
|
|
line to make their presence easier to spot.</p>
|
|
|
|
<p>The -asxml mode now inserts the appropriate Voyager html
|
|
namespace on the html element and strips the doctype. The html
|
|
namespace will be usable for rigorous validation as soon as W3C
|
|
finishes work on formalizing the definition of document profiles,
|
|
see: <a
|
|
href="http://www.w3.org/TR/WD-html-in-xml/">WD-html-in-xml</a>.</p>
|
|
|
|
<h2>13th November 1998 and earlier releases</h2>
|
|
|
|
<p>Fixed bug wherein <style type=text/css> was written
|
|
out as <style type="text/ss">.</p>
|
|
|
|
<p>Tidy now handles wrapping of attributes containing JavaScript
|
|
text strings, inserting the line continuation marker as needed,
|
|
for instance:</p>
|
|
|
|
<pre>
|
|
onmouseover="window.status='Mission Statement, \
|
|
Our goals and why they matter.'; return true"
|
|
</pre>
|
|
|
|
<p>You can now set the wrap margin with the -wrap option.</p>
|
|
|
|
<p>When the output is XML, tidy now ensures the content starts
|
|
with <?xml version="1.0"?>.</p>
|
|
|
|
<p>The Document type for HTML 2.0 is now "-//IETF//DTD HTML
|
|
2.0//". In previous versions of tidy, it was incorrectly set to
|
|
"-//W3C//DTD HTML 2.0//".</p>
|
|
|
|
<p>When using the -clean option isolated FONT elements are now
|
|
mapped to SPAN elements. Previously these FONT elements were
|
|
simply dropped.</p>
|
|
|
|
<p>NOFRAMES now works fine with BODY element in frameset
|
|
documents.</p>
|
|
</body>
|
|
</html>
|
|
|
