Re: [l2h] Adjusting itemize row spacing
I would like to adjust the spacing between items in the itemize
environment. I read on a latex list that the way to do this was to
adjust the \itemsep length just after the \begin{itemize} statement:
\itemsep is not interpreted by LaTeX2HTML, since there is nothing
corresponding to it in the HTML specs.
The simplest way to get extra space after an \item
is to leave a blank line after the item's contents,
before the next \item.
LaTeX will ignore this extra space, but LaTeX2HTML
interprets it as a new paragraph, so puts an unclosed P tag.
(This remains valid HTML.)
\documentclass[10pt,oneside]{article}
\usepackage{html,htmllist,color,makeidx,epsfig}
\begin{document}
\begin{itemize} \addtolength{\itemsep}{0.5\baselineskip}
\item Doctor of Philosophy (Ph.D.)
\begin{itemize}
\item \htmladdnormallink{General information}
{http://www.gradschool.cornell.edu/grad/fields_1/oper-res.html}
\item \htmladdnormallink{Degree Requirements}{/~kathy/phd/phdreq.html}
\item \htmladdnormallink{How to apply for a Ph.D. in Operations
Research }{/
~kathy/phd/phd4.html}
\end{itemize}
\item Master of Engineering (M. Eng.)
\end{itemize}
\end{document}
This works for latex, but makes no difference in latex2html. I am using:
E:\LATEXlatex2html -v
This is LaTeX2HTML Version 2002-1 (1.69)
by Nikos Drakos, Computer Based Learning Unit, University of Leeds.
Related to this, I would like to change the the appearance of the itemize
levels to be \Large in the first level and italicized on the second level.
How is this accomplished?
One way is to simply apply the styles that you want to the contents
of your \item s, using explicit \textit commands, or pseudo-environments,
such as {\Large }.
An alternative way would be to use CSS styles.
You can edit the stylesheet that LaTeX2HTML creates when you first
process a job.
HTML is not a rich language for delicate page-layouts.
You must either combine it with CSS, or try a different format, such as PDF.
Hope this helps,
Ross Moore

Re: [l2h] numbers in references
Hello latex2html,
I need to use numbered references to formulas, but I have buttonlike
rectangles instead? Why dous this happen? How do I fix it?
Have you run LaTeX on the document source, so that a .aux file is available
to provide those numbers ?
LaTeX2HTML writes a message to the screen-log if the .aux file is not found.
(Look inside the WARNINGS file of an old job.)
You may also need the -show_section_numbers switch,
or set $SHOW_SECTION_NUMBERS = 1; in an initialisation file.
As for your problem with {multline} environments,
do you have a URL where I can view an example of this kind ?
It should have the command-line that you used on the About this document...
page, and I also want to look at the HTML of the bad environment.
Hope this helps,
Ross Moore

Re: [l2h] Help with converting a latex file using latex2html (newbie)
[Charset iso-8859-1 unsupported, filtering to ASCII...] Hi, I had never used latex before, and i want to convert a latex file to HTML..From some news posts i fpund that latex2html is a good tool for doing this.. However i am sort of confused with the described usage of the various sqwicthes... Can someone please send me an example .latex2html-init file that i can use as a reference. Here are some of my requirements: I have a *.tex file with images (in .eps format) and some mathematical equations. I just need to convert it to one single html page, with no navigation , no footnotes, .. the images must be inline .. and the mathematical expressions must also be converted to images. Also the references must be maintained. (I do not know what other features i can use, and am open to suggestions). Just use: latex2html -split 0 -no_footnode -no_navigation mydocument.tex See how that works, and list the things that you might want done differently. There should be a switch to accommodate each of those things. If the command-line starts to get too long, then you can think about using an initialisation file instead. Any help is greatly appreciated. The best advice is don't expect to get everything exactly right first time. Try it out, then work on the differences.

Re: [l2h] Macro and best-solution for URL
hello Ben,
you wrote:
Macro are not analysed by latex2html and definitions are lost. For
instance,
\newcommand{\email}[1]{\htmladdnormallink{#1}{mailto:#1}}
and then \email{[EMAIL PROTECTED]}
produce only the argument ([EMAIL PROTECTED] in that case)
in basic HTML text inside the final HTML document.
Macro definitions are certainly supposed to be recognised.
That is a basic part of LaTeX2HTML, and any TeX-like system.
If it didn't work for you, then there should have been some messages
in the output-log, when you ran the job.
Presumably it quite a long involved job, and so it is possible for
various things to have gone wrong.
Is-it possible to define very simple macro or to provide a definition of
those macro for latex2html ?
In fact \email is already defined for LaTeX2HTML, as part of the way
to specify author information in the top-matter of a document.
This is similar to \address as used in AMS document classes.
e.g.
\title{My Document Title}
\author{This is me}
\address{Where I live\\city and state}
\email{[EMAIL PROTECTED]}
\maketitle
It is not advisable to redefine built-in commands of LaTeX2HTML.
Since the processing order is different to other TeX-like programs
it is hard to predict the consequences.
Moreover, what is the best solution to manage URL :
the html package ? the url package ? href package ? another package ?
The html package provides very useful constructions for using hyperlinks
in HTML documents.
It also provides Conditional Code constructions, that allow for different
definitions according to what processor is being used with to process your
document source.
Have you seen the online documentation?
Visit www.latex2html.org to find it.
(well for the moment, we are building pdf document and for that we use href but with
some macro so if we have to change all of that, let's do it cleanly -
our only prerequisite is that it works with pdflatex too ;-)
Sure. You will need to experiment a bit, and be prepared to adjust macro expansions
to adapt to what works best in the different settings.
That's why the Conditional Code constructions of the html package are so useful.
Thanks by advance,
Hope this helps,
Ross Moore

[l2h] Re: Info about custom_title_hook
[Charset ISO-8859-1 unsupported, filtering to ASCII...]
Hello,
I am currently working on a multimedia project for teaching numerical
methods to engineers with the Web.
I use latex to generate texts and latex2html for html translation.
I need to replace the usual names 'node1.html, ...' by the number of the
section concerned.
For this, I first use the following instructions :
\renewcommand{\thesection}{\Alph{section}}
\renewcommand{\thesubsection}{\thesection.\Alph{subsection}}
\renewcommand{\thesubsubsection}{\thesubsection.\Alph{subsubsection}}
in order to obtain an alphabetical section title.
For example, it will give section titles of the form 'AAAB, AAAC, ...'
The idea is to finally obtain files named 'AAAB.html, AAAC.html, ...'
replacing 'node1.html, node2.html ...'
I know that we may generalize this approach in using the perl program
'custom_title_hook'.
This should come pretty close to what you want.
The logic is easy enough once you realise that the level-numbering
is available, independent from section-names.
sub custom_title_hook {
my ($i,$A,$return) = (0,'0','');#initialise variables
my @sects = split (/_/, $packed_curr_sec_id); #get level numbers
while ($A eq 0) { $A = shift @sects }; #discard leading 0s
while ($i 4) {
$return .= fAlph($A); #convert number to letter
$A = shift @sects; #get next level
++$i; #increment counter
}
$return #should be 4 letters
}
This hasn't been tested.
I hope it works OK.
Hope this helps,
Ross Moore
The problem is that I don't know how to write this subroutine in Perl, I
have no experience in Perl language.
If this doesn't take to much time for you, would you be able to send me
the subroutine?
It will give me so much help because the number of sections is about 300.
Thanks a lot in advance and for helping non developers to use latex2html.
Sincerely yours

Re: [l2h] Changing default calours in frames
I am currently generating html with frames using LaTeX2HTML Version
2002-2 (1.70) and I was wondering whether there was any (simple) way to
change the default colours used in the frames. Although the peach and
purple are quite pleasant, they don't fit in with the colour scheme for
the rest of the site.
Find the module frames.perl in the directory $LATEX2HTMLDIR/styles
where $LATEX2HTMLDIR is the base location for the LaTeX2HTML libraries,
as set at the beginning of the installed latex2html script.
Then a simple grep will tell you what you need to know;
e.g.
landau.ics.mq.edu.au grep COLOR frames.perl
$TEXT_COLOR = bgcolor=\#ff\ text=\#00\ link=\#9944EE\ vlink=\#ff\
alink=\#00ff00\
unless $TEXT_COLOR;
if (!$NOFRAMES) { $MAIN_COLOR = bgcolor=\#00\ text=\#ff\ unless
$MAIN_COLOR;}
else { $MAIN_COLOR = bgcolor=\#ff\ text=\#00\ unless $MAIN_COLOR; }
$NAVIG_COLOR = bgcolor=\#ffeee0\ text=\#00\ link=\#9944EE\
vlink=\#FF\ alink=\#00ff00\
unless $NAVIG_COLOR;
$FOOT_COLOR = bgcolor=\#e0\ text=\#00\ link=\#9944EE\ vlink=\#ff\
alink=\#00ff00\
unless $FOOT_COLOR;
$TOC_COLOR = bgcolor=\#8080C0\ text=\#ffeee0\ link=\#e0\ vlink=\#e0\
alink=\#00ff00\
unless $TOC_COLOR;
...
...
Thus you see the default settings for the variables used for the color sets
in the different frames:
$TEXT_COLOR, $NAVIG_COLOR, $FOOT_COLOR, $TOC_COLOR
(and also $MAIN_COLOR for when there are no frames).
As well as the background and text colors, the color sets include the 3 different
colors for link-text of hyperlinks: tested/untested and while being pressed.
Set these in an initialisation file, to have whatever colors you like,
and the defaults will be ignored.
I apologise if this question has been asked before but I couldn't find
anything on the archives that seemed to match my request.
Thanks in advance for any help,
Hope this helps,
Ross Moore

Re: [l2h] alltt gives meaning to more than \ and the braces
Hi there,
latex2html seems do more than it should:
\begin{verbatim}
--foo
bar
\end{verbatim}
and
\begin{alltt}
--foo
bar
\end{alltt}
look the same when processed by LaTeX, however, latex2html converts
alltt environment to an interesting result:
DIV ALIGN=LEFT
TT
-foo
the -- ligature == endash has acted here.
BR#187;bar
this is another ligature pattern, for guillemot quotes
BR/TT
/DIV
That looks like a bug to me. ;)
Perhaps.
The {alltt} environment is basically a hack, which is quite
hard to emulate without following the TeX processing model
exactly --- LaTeX2HTML is not designed to do that.
If you really mean verbatim, then you should use
a {verbatim} environment.
Is there a way to turn this processing of?
Not easily, as there is no notion of \catcode in LaTeX2HTML.
It would require a major change to how the {alltt} environment
is processed.
You could add a post-processing routine, to find the bad patterns
that are characteristic to this document, and fix them.
However, it's value for other documents would be questionable.
Hope this helps,
Ross Moore

Re: [l2h] cannot find file in \input
Hello Ger,
The option -debug learned me that texexpand does not take TEXINPUTS
into account, but seems to use a more or less predefined path.
Yes; your analysis is absolutely correct.
Now is my question:
Can I tell latex2html to look into 199.dir to find taql.tex or do
I need to change the \input line into \input{199.dir/taql.tex} ?
The latter would be tedious, because there are many more such files.
You could use conditional commands to \input from different directories
when using LaTeX2HTML, and when not.
But yes, this is tedious.
Much more elegant is to set the $TEXINPUTS Perl variable
in a .latex2html-init file for your job.
Another question is why latex2html does not take TEXINPUTS into account
anymore. It used to do it.
It doesn't do it (and has not since 1998 or 1999) since typically
the TEXINPUTS variable is set (rightly or wrongly) to include the whole
texmf/ tree. It is then very easy to pick up the wrong .tex file
in many situations.
Furthermore, it is quite typical that files that are expected to be
found via the TEXINPUTS environment variable contain code that is quite
irrelevant to an HTML translation. This is the same reason that .sty files
are typically not loaded.
The Perl $TEXINPUTS variable serves the desired purpose.
The need to set it separately requires the author to think about whether
the commands in their \input files will have proper HTML support for the
macros that they define, or whether more work needs to be done to obtain
a sensible translation.
Hope this helps,
Ross Moore

Re: [l2h] Top of images are not cropped
I use latex2html to produce png images, but it doesn't crop the top of
the images enough.
I would like latex2html either to have a switch for setting the -crop
argument which pstoimg uses, or that the default for crop to minimum
size (line 3592 in version $Id: latex2html.pin,v 1.70 2002/08/22
15:14:08 RRM Exp $) was $crop{$name} = blrlt instead of $crop{$name} =
blrl.
I think the intenion here is to first crop away the cropping bars,
via the b and l , then remove extra space on the left and right,
since TeX has centered the environment's contents on the printed page.
In HTML that extra space is not needed.
There is not t cropping, because the cropping-bar at the left-hand side
was initially placed to be the correct height for the environment;
similarly there is no second b crop after the bars have been removed.
What should I do in the meantime?
The best answer is surely to determine what is creating the extra
space that you are trying to remove.
It *should* be the \abovedisplayskip or \abovedisplayshortskip
parameter in TeX.
If this is so, then try putting code such as:
\begin{imagesonly}
\AtBeginDocument{\abovedisplayskip=0pt \abovedisplayshortskip=0pt}
\end{imagesonly}
into the document preamble, assuming that \usepackage{html} has been
used earlier in the preamble.
I tried to use mogrify, but it has problems with the transparency and I
don't know how many pixels I can crop.
Yes; that's why LateX2HTML uses pnmcrop , since there's no easy way
to find out how much to crop.
Hope this helps,
Ross Moore

Re: [l2h] hello everybody
I'm a student at Department of Computer Science, Dresden University of
Technology. My job at University is converting documentation into the
HTML-Format for using by handycaped students at my Department.
The students can read the HTML with lynx and very large literal on the
console.
This is a good thing, and the converter latex2html is mostly a great
start for me.
But, I have two large problems in this situation:
First.
The goal is a page-to-page conversation to HTML. If I have a tex-file I
can use LaTeX and make by the end a ps-file. At this ps-file the layout
at page is ok.
The important point in this situation is the HTML-file the converter
make a file chapter to chapter, not page to page.
You can make the translator split files at any sectioning-level;
e.g. \subsection \subsubsection \paragraph etc.
Use the -split num switch, or set the $MAX_SPLIT_DEPTH parameter.
What can I do to convert a page-of-page document?
Furthermore, you could define your own markup to be a sectioning command
for LaTeX2HTML, but do nothing with normal LaTeX processing.
That sounds like an appropriate thing for your situation.
Consult the documentation for how to do this.
And second.
If the converter found a large picture, he wrote as HTML alternative-tag
TeX-code. It' s ok, but in the center he make two cuts and the code is
not complete.
Yes; that's true.
The maximum length of the coding is ~200 characters, for compatibility
with older database (DBM) software with Perl.
You could change this, with some strategic edits in the latex2html Perl script.
(Better is to find the appropriate subroutine, then place an edited copy
within an initialisation file.)
This is very bad, the students can't reading the uncompletly TeX-Code.
... do they really *want* to read the TeX code ?
If the image is of a text-based environment, then it is surely better
to devise an appropriate translation into HTML.
Use conditional coding:
\usepackage{html}
\begin{htmlonly}
\renewenvironment{myenv}
{... start of simpler LaTeX environment(s) ... }
{... end of simpler LaTeX environment(s) ... }
\end{htmlonly}
What is the way for the correctly TeX-Code at the HTML alternative-tag?
You can do this using the \htmlimage command,
which can be placed anywhere with an environment that will be converted
into an image. (If not an image, the \htmlimage command will be ignored.)
Try either:
\htmlimage{... other options... , ALT= alt-text }
\htmlimage{... other options... , alt-text }
In the latter case, everything that is not identified as one of the
specific options is interpreted as being for the ALT attribute.
(Beware of using ',' within the ALT-text.)
thanks and regards from Dresden/Germany

I'm guessing that the full path to Ghostscript was not found when you installed

This means that some variables, name $GS and starting $GS... will have empty

You could try to find these and fix them, or wait until the installer is patched
to recognise this latest version of Ghostscript.

Re: [l2h] dots im mathematical formula tooltip
Hi,
after the compilation of a mathematical formula with latex2html we
normally get a GIF or PNG which contains the formula. If I move with the
mouse in IE or NS over the formula I get a tooltip with the
corresponding Latex code. However, if the Latex code is too long some
parts of the formula are replaced by three dots. Does anyone know how we
can always get the full Latex code in the tooltip ?
There is a reason for the truncation, at least on older Perl systems.
You can experiment with changes to the following block of coding,
from the latex2html script, part of the sub extract_parameters block:
if (!$alt) {
#...catching all the code for the ALT text.
local($keep_gt)=1;
$alt = flatten_math($contents); undef $keep_gt;
#RRM: too long strings upset the DBM. Truncate to = 165 chars.
if ( length($alt) 163 ) {
local($start,$end);
$start = substr($alt,0,80);
$end = substr($alt,length($alt)-80,80);
$alt = join('',$start,...\n ...,$end);
}
Hope this helps,

Re: Re: [l2h] Why images cannot be generated?
Dear Ross Moore,
Thanks for your help. Stragely, it seems that config.bat have successfully find AFPL
Ghostscript 8.00. The following is the segmented texts in config.log after running
config.bat:
...
checking for gswin32c... C:\gs\gs8.00\bin\gswin32c.exe
checking for ghostscript version... 8.00
...
Hmm.
So it looks like it found that OK -- which is good.
That leaves me mystified about what else might be the problem.
Similarly, the following is the segmented texts in pstoimg.bat after running
install.bat:
...
# Ghostscript
my $GS = 'C:\\gs\\gs8.00\\bin\\gswin32c.exe';
my $GSDEVICE = 'pnmraw';
my $GSALIASDEVICE = 'ppmraw';
...
Looks good.
Search path:

For more information, see c:/gs/gs8.00/doc/Use.htm.

pstoimg.bat: Error: Ghostscript returned error status 0
pstoimg.bat: Error: Couldn't find pnm output of

So it looks like Ghostscript got started, but it failed for some reason.
Run your job again, using the -debug switch.
Post the output to the terminal that results.
Perhaps some of the extra messages will reveal something useful.
This will also retain intermediate files, such as the .ps files,
and show LaTeX messages as well.
It may be that something is missing for LaTeX, resulting in one or more
empty, or otherwise bad, images.
Hope this helps,

Perl is installed and all the netpbm executables and dlls are in the right place, gswin32c is accessible and all the directories are specified in prefs.pm, but when I run the config.bat, I get a message that some missing external programs are missing (I can't get more information!). Here's the message. ... building pstoimg build.pl (Revision 1.6) config\build.pl: Warning: Skipping build of pstoimg because of missing external programs. This should only happen whin the pstoimg.pin (pre-installation version of pstoimg ) is what is missing. Are you sure that you are running the install script from the correct directory ? Does anyone out there have any idea of what this could be? Did you run the configure script first, to create the file cfgcache.pl ? There should be an entry in there for have_pstoimg . If that's missing or empty, then you will get the message that you saw. Hope this helps, Ross Moore Nicholas ___ latex2html mailing list [EMAIL PROTECTED] http://tug.org/mailman/listinfo/latex2html
Re: [l2h] Questions on implementing ifthen.perl
While the conditional commands in the html.perl package are great when
choosing which code to process depending on latex2html or LaTeX2e are
being used, I sometimes need conditional processing when processing
with LaTeX2e. I assume html.perl can't do general purpose conditional
processing with LaTeX2e?
I have a partially complete implementation of ifthen.perl to support
\ifthenelse{condition}{cond true commands}{cond false commands}
One thing that stymies me is that the parameter sent to
do_cmd_ifthenelse is delimited by the next \section/\subsection
Yes; LaTeX2HTML calculates the document-structure before it expands
macros. So this can never work.
Essentially you have one document for when the condition is 'true' and
a different document for when the condition is 'false'.
If the condition changes according to the contents of the LaTeX source,
then LaTeX2HTML will not know this at the correct time.
(Your model is then of document-content determining document-structure;
this is very much against the tree-like structure of HTML and XML documents.)
On the other hand, if it changes according to some externally-supplied
input; e.g. something that is set once in the LaTeX preamble, and never
changes after this, then you can use Perl coding to set declarations
that will enable you to handle it.
e.g.
Study comment.sty with its conditional 'comment' environments.
Surround your conditional sections by comment-like environments.
Develop the logic to handle \includecomment and \excludecomment
commands.
Alternatively, your conditional sections could be \input from separate
files. Adjust the values of $DO_INCLUDE and $DONT_INCLUDE within the
.latex2html-init file, before starting the LaTeX2HTML job.
command. This produces problems if you want to conditionally process a
section, i.e.
\ifthenelse{\boolean{dothissection}}
{
\section{This is a section that will be processed if dothissection is
true}
And it's contents.
}
{
\section{This is a section that will be processed if dothissection is
false}
And it's contents.
}
I assume that ifthenelse needs to be processed via
substitute_meta_cmds since according to the documentation, these are
processed prior to splitting the input text into chunks at section
boundaries?
Yes; I suppose that is an alternative approach.
But it all depends upon what determines when you want the sections included
or not included. If it is something that will not be known until detailed
expansion of macros has taken place, then you are out of luck.
If it depeneds on some global parameter that is known at the very start of
the job, then there is almost certainly a better way to organise your LaTeX
sources that makes the relevant logic easier to handle.
The other issue raised in a previous mail list posting by Ross is it
seems booleans are not guaranteed to expand in the same way in
latex2html than in LaTeX, I can live with/work around that, although
fairly simple set of commands like
\newboolean{condition}
\setboolean{condition}{true}
\boolean{condition}
in 1.70 of latex2html.pin always produce 0. I've sent the changes to
Ross to fix those bugs in \boolean processing. However, am I correct in
assuming latex2html-2002-2-1.tar.gz is still the latest release?
Yeah; sorry.
I've been too busy to make those changes generally available.
I'd need to study examples to ensure that they work correctly,
and establish guidelines on just what working correctly actually means.
As my above comments indicate, use of \ifthenelse is not a good idea for
controlling document structure.
I don't want to make such commands available, and then have to field dozens
of complaints that users are not getting what they expected to get.
This is the surely the real reason why these commands were never implemented
years ago. (Giving unexpected wrong results is worse than giving no results
at all, for this kind of thing.)
The link http://saftsack.fs.uni-bayreuth.de/~latex2ht/current/ from
www.latex2html.org lists all files as written on the 29th of November
2002, I assume the other ones cover releases in 1999 (i.e
latex2html-99.2beta8.tar.gz) and 2000 (latex2html-2K.1beta.tar.gz)?
Do I understand that to mean latex2html-2002-2-1.tar.gz does not change
it's name when updates have been made, or that no changes have been
made since the 2002-2-1 release?
I'm sorry for all the questions, but the version numbering in the name
of the tarball seems non-standard. Also, am I correct in assuming that
the CVS repository itself is not accessible but only a checked out
distribution accessible at
http://saftsack.fs.uni-bayreuth.de/~latex2ht/user/?
With Marek Rouchal returning after a long absence, the anonymous CVS
logins may become accessible again soon.
THanks for your interest, and hopefully there will be more time
in the New Year to make further improvements to LaTeX2HTML.

Re: [l2h] Already generated image inclusion
Hi Herb,
Great to hear from you after so long.
I just stumbled on this possible solution to a previously posted
question of how to include an already generated (bitmap) image
into both the html and ps versions of the document. It is not
documented, but it works too well for it not to have been a
designed feature.
Yes.
The latest versions of LaTeX2HTML have revamped graphics.perl
and graphicx.perl via a new module graphics_support.perl
written by Bruce Miller of NIST.
In this example, my already generated images are in gif format,
and are located in the snaps directory relative to my latex
source.
%
% Allow the insertion of gif images from the snap directory.
%
\usepackage{graphicx}
\DeclareGraphicsExtensions{gif}
\DeclareGraphicsRule{.gif}{eps}{.bb}{`giftopnm #1|pnmtops -noturn -rle}
\graphicspath{{snaps/}}
\newlength{\gifwidth}
%
% The \showimage command displays a gif image in html,
% and a PostScript version of it in the ps document. The optional
% argument 'width' overrides the natural width of the image.
%
% Usage: \showimage{image}{caption}
% \showimage[width]{image}{caption}
%
\newcommand{\showimage}[3][0.9\textwidth]{%
\setlength{\gifwidth}{#1}
\begin{figure}[htb]
\begin{center}
\vspace{1ex}
\includegraphics[width=\gifwidth]{#2.gif} \\
\caption{\label{#2}#3}
\hrulefill\htmlrule
\end{center}
\end{figure}
}
Apparently, latex2html is smart enough to not attempt to convert
an image with the .gif extension into PostScript. Instead, it
simply inserts the image reference into the html file. The latex
Bruce's coding allows support of many more graphics formats. It first
determines whether a conversion is necessary or not, by looking at the
filename suffix for whatever files it can find in the local directory
having the correct prefix, then it makes use of many more of the various
netpbm modules to do any required conversions or transformations.
Essentially *all* of the options to LaTeX's \includegraphics command are
supported, including rotations, scaling and cropping to a specified size.
version instructs dvips to convert the gif to PostScript on the fly.
It does, however, require you to precompute the size of the gif
file in a nonbinary format that latex can read. You can do this
in a makefile via
%.bb: %.gif
giftopnm $ | pnmtops -noturn -rle | grep BoundingBox $@
and listing the .bb files as dependencies to the .dvi file.
You might try this with .png images by making the appropriate
changes to the \showimage macro, and declaring a different
GraphicsRule to convert png to ps.
PS - I can see that a lot of improvements have been made to lates2html
since the lst time I worked it. Ross, I'm glad to see that you're
still very actively involved!
It gets a bit of tinkering when someone reports abnormal behaviour which
can be traced to being a real bug. (That doesn't happen very much anymore,
thanks to the great work that has been put in over the years by many people,
yourself included.)
All the best, and have a great New Year
Ross

Re: [l2h] Nested enumerated lists
Hello all,
We are within days of final production and we have *just* noticed that
our nested
enumerated lists are not functioning as we expected.
We want:
1. Blah blah blah
2. Blah blah blah blah blah
a. some more blah blah
b. even more blah blah
3. Blah blah
We get:
1. Blah blah blah
2. Blah blah blah blah blah
1. some more blah blah
2. even more blah blah
3. Blah blah
Hmm; the enumeration level is supposed to be handled automatically.
However, the label-style can be forced, using an optional argument:
\begin{enumerate}
\item % 1.
Blah blah blah
\item % 2.
Blah blah blah blah blah
\begin{enumerate}[a]
% ^^^-- here.
\item
some more blah blah
\item
even more blah blah
\end{enumerate}
%
\item % 3.
Blah blah
\end{enumerate}
You may need to load \usepackage{enumerate}
to have this working in LaTeX,
but LaTeX2HTML needs nothing extra to interpret this syntax.
Is there some switch I need to set in latex2html? The older version
of latex2html handled this problem, why doesn't this version?
I'd need to see your document's contents, to have any chance of answering
that question.
(I know I don't have the most current version. I really don't want to
upgrade at this point.
But if I must...)
That might help; but I don't recall that there have been any edits
of this nature recently.
Hope this helps,

[l2h] Re: \H{} diaresis not working in l2h
Hi Aaron,
Hi Ross, do you know if anything can be done about this issue:
http://bugs.planetmath.org/cgi-bin/bugzilla/show_bug.cgi?id=101
\H{letter} specifies the Hungarian umlaut.
So far as I know, there are no special entity names or numbers
for characters using this accent --- certainly not in ISO-8859-1
but maybe there is something in another encoding.
In TeX, the only way to support this (that I know of) is by making
an image of the required accented character.
In LaTeX2HTML, you need to set $ACCENT_IMAGES to obtain this;
e.g. $ACCENT_IMAGES = 'textrm';
so that you get a roman font in the image.
($ACCENT_IMAGES = 'textit'; would give italiced accented chars.)
I assumed at first that it was a bug, but maybe there's a reason it
can't be done (is there any HTML entity support for it?)
Are there Unicode points for letters with Hungarian umlauts ?
If so, I've never been advised of what these are.
In any case, do browsers support these code-points?
(If not, then there is no point in using them, at this stage.)
I've not readdressed this problem for ~3 years.
Perhaps in that time new possibilities have arisen.

Re: [l2h] cropping bars --- problem persists :(
hello Carlo, Our mileage varies, Christian! I looked into my l2conf.pm, but it had only the option -E for dvips; so, unfortunately, Shihegaru's solution works for Christian but not for me; I am appending some debugging output from latex2html; the figure img9.gif has a cropping bar at the bottom; It is the case that some characters put ink outside their typeset-area, either above or to the right. This is particularly the case with florid type-faces, and with accents used in math-mode. Since you report problems with just some images and not all, then this is probably what is happening. Can you show the LaTeX coding that is used for this img9.gif ? You should be able to find it within the images.tex file. LaTeX2HTML allows a small margin to help account for this effect, but it cannot cater for the extreme cases without upsetting more usual situations. That is, the lower cropping-bar extends approx .5pt to the right of the true typesetting width, and ~ 1.5pt above. If ink falls outside the rectangle defined by this, then the pnmcrop calls will not find an edge of constant color, so will not remove the corresponding cropping-bar. I'm clueless how to fix this... Sometimes you just have to do it by hand in the LaTeX source. This can mean adding a small bit of extra space within the image. At the right, this is easy: just put \, after the mathematics but within the $.\,$ ^^- like this. For extra vertical size, \strut may help; e.g. $ \strut$ else an invisible \vrule of specified size: \vrule height 15pt depth 0pt width 0pt Hope this helps, Ross Moore Carlo Beenakker Christian Mensing wrote on Fri Jan 31 14:34:36 CET 2003 thanks to Shigeharu TAKENO the cropping problem was solved!

[l2h] Re: \H{} diaresis not working in l2h
Hi Aaron,
#337; in Unicode does Hungarian-umlauted o.
I've basically abandoned Latin-1 PlanetMath uses UTF-8 Unicode. All
modern browsers support this (and the page can force the encoding both in
the http header and with META tags, taking care of the case where the
user sets another charset as default).
In that case, you should be using the command-line switches:
latex2html -html_version 4.0,latin1,unicode,utf8,.
or have the $HTML_OPTIONS variable set to include these.
While you are thinking about this topic, please test this.
These extensions have been available for a long time now,
but I've not seen many examples of web-pages using them.
In the last 3 years, I'd say the installed base of software has shifted to
being able to handle Unicode, so I would definitely advise making it
supported and default.
It would be nice to think that most of your audience is keeping up.
Hopefully that is true, at least in the more affluent countries.
This page is a useful resource:
http://www.unicode.org/charts/
The offending o is on the Latin Extended-A chart.
With the 'latin1,unicode' options as above
(actually the 'latin1' should be redundant)
then LaTeX2HTML should catch the \H{o} and replace it by #337;
With also 'utf8' (or $USE_UTF8 = 1; )
then this #337; should be replace by a 2-byte sequence, later in
the processing.
If you cannot get this to work, then report back to me with an example
(and a URL to the bad results).
Hope this helps,
Ross

Heh, it was a silly problem: I run l2h's output through TIDY to turn it into XHTML, and it was tidying up the UTF-8.

Re: [l2h] img placement problem
In relation to an earlier request:
Look in the images.log file, produced when the job was last
run, requiring images to be generated.
Does that show any bad errors that may be related?
There are errors in the images.log file. It seems that
when the images.tex file is generated there is a \begin{document}
tag in two places, and \newcommand tags are repeated.
With \usepackage{html} there are conditional environments:
\begin{latexonly}
...
\end{latexonly}
\begin{html}
...
\end{html}
\begin{imagesonly}
...
\end{imagesonly}
and special comments:
%begin{latexonly}
%end{latexonly}
which let you mark blocks of LaTeX source
(particularly in the preamble) as being
relevant to certain types of processing only.
This lets you control precisely what goes into the preamble
of the images.tex file, so that it doesn't conflict with
the special requirements of that file, and so that it
doesn't include stuff that will create redundant images.
For example, anything to do with a title-page has no bearing
on the making of images, so ought to be excluded.
Spend some time adjusting your preamble, to get your document
working properly.
You will then be able to use the same preamble with other, similar
documents, and get good results from LaTeX2HTML.

Dear Dr Ross Moore, When I convert *.tex into HTML with your latex2html (ver. 1.47 or 2k.1beta), I found (1) the *.gif or *.png images always have a 'L-shape' border around, which I don't need. Did you install the netpbm utilities ? The symptom you describe is due to pnmcrop failing to work correctly, to remove those 'cropping-bars' which are used to ensure that the resulting image is cropped to the correct size. (2) the LaTeX command \dotfill was not recongized by latex2html How can this possibly be translated into HTML ? To get proper vertical alignment, you *must* use a TABLE ; then there is no use for the \dotfill as the material before/after the filler would be in different cells. I check the manual document but I did not find an answer. Could please you tell me how to solve the two problems. Thank you very much in advance.

Re: [l2h] counter for figures
Hello Christian,
hello Ross,
here is one example of a code:
OK.
You are mixing physical and logical markup,
to place the caption side-by-side with the image.
In HTML the CAPTION can only be placed above or below,
so the use of \parbox just gets in the way.
Adjust your coding as follows:
\begin{figure}
%begin{latexonly}
\begin{tabular}{cc}
%end{latexonly}
\input{\xfigpath/al2_6_H2O2.pstex_t}
%begin{latexonly}
\parbox[b]{.45\textwidth}{%
%end{latexonly}
\caption[Struktur des H$_2$O$_2$-Molek\uls.]
{\small Struktur des H$_2$O$_2$-Molek\uls. \newline
Die vier Atome des Molek\uls bilden eine verdrillte Kette.
Durch die Verdrillung wird die Abstossung der freien Elektronenpaare der
Sauerstoffatome verrringert. Die noch vorhandene Abstossung ist die
Ursache f\ur die geringe Bindungsenergie der O--O-Bindung.}%
\label{fig:H2O2}%
%begin{latexonly}
}% end of \parbox
\end{tabular}
%end{latexonly}
\end{figure}
This should not change the result from LaTeX,
and it lets LaTeX2HTML see just:
\begin{figure}
\input{\xfigpath/al2_6_H2O2.pstex_t}
\caption[Struktur des H$_2$O$_2$-Molek\uls.]
{..}
\end{figure}
and do something sensible with it.
The figure number for the caption will be correct provided the caption
can be matched with what has been written into the .aux file for the
whole job, when processed by LaTeX.
BTW, did you consider using \begin{tabular}{cp{.45\textwidth}}
or \begin{tabular}{cb{.45\textwidth}}
along with \usepackage{array} and/or \usepackage{tabularx} ?
The small picture is placed inside a tabular to get the caption
on the right free space. The parbox makes an image of the caption.
Logically it is not a caption, but simply a picture.
This will upset the book-keeping for the document-structure.
The current figure number in the latex version is 70, in LaTeX2HTML
it is No 9 (due to previous similar occurences). No 70 is missing
in the l2h, No 71 is ok again.
The #9 comes from counting \caption occurrences within the images.tex
file. It is not related to the numbering of figures within the HTML,
since not all figures have their captions processed this way.
LaTeX2HTML has not been programmed to adjust the {figure} and {table}
counters for each image, since this could easily conflict with the
image-reuse mechanism.
Perhaps the LaTeX coding for an image could be scanned for '\caption'
and the counters set when this occurs. But doubtless there are cases
where this would conflict with something else.
Personally, I think it best that you adjust your LaTeX source to avoid
including the values of counters inside images --- the counter value
is *not* part of the content of the figure, but merely part of the
book-keeping which governs the overall document structure.
The URL of the resulting HTML page is
http://www.cci.ethz.ch/vorlesung/de/al2/node35.html
Each time the caption is displayed as an image, the
image caption counter is used instead of the figure counter.
All image captions are listed in images.aux:
The image caption counter, as you call it, is the value of the {figure}
counter for the images.tex run. It is not part of the sequential numbering
of images for the job as a whole.

Perfect, if this file was the .aux for the whole job.
Then the captions could be matched...
images.aux: END

there is nothing in there that could be of any use.

Yes; it explains perfectly why you get what you described.
Hopefully you understand my explanation, and appreciate the value in
adjusting your document source. Interesting problem!

Re: [l2h] sections..
Hello Joao,
Is it possible to define which sections should be generated in different
HTMLs? Some times I use something like \HTMLcode{H2}{xxx}, when my
sections are too small. But they do not appear in content table.
This cannot work, as all that \HTMLcode does is to construct and place
raw HTML into the output files.
Thus you get the presentation aspects of the section tags,
but this is not part of the LaTeX document structure, via \section
\subsection, etc.
LaTeX2HTML uses the -split and -link options to determine
which sectioning levels should produce new pages.
These adjust Perl variables $MAX_SPLIT_DEPTH and $MAX_LINK_DEPTH
to control the splitting and linking.
It is actually possible to alter these within a running job,
using \HTMLset and/or \HTMLsetenv , but that is rather awkward,
and can upset the table-of-contents if you make too many changes,
since there is no way to know what on-the-fly changes to these variables
were made at the time when the T-of-C is being constructed.
Nevertheless, you should get a useful HTML web-site.
Hope this helps,
Ross Moore

Re: [l2h] table border...
Is there some how to put no line border into my tables?
LaTeX2HTML is not very smart about borders; it only chooses between
no border and all cells bordered.
This choice is made by looking at the column-specifier
(e.g. \begin{tabular}{llc} )
^
for the presence of column rules | .
Any such | character turns on the border.
Also, the presence of \hline (and maybe \cline too)
within the table's contents also turns on the border.
This dates from the time when HTML only allowed all or none
for borders. It would be nice to have a way to do more
detailed specifications of column and row lines, via
attributes to cell tags.
Hope this helps,

i've been hacking latex2html's source code (version 2002-2-1) about a bit (just to make it do what i want), and am going to try turning some what i've done into useful patches. it looks to me as if some of the files in versions/html*.pl are obsolete: if i could have that confirmed/denied, then i could be sure i'm preparing patches for just the relevant files. specifically ... -rw-r--r--1 phil phil20274 Jul 11 1999 versions/html2_1.pl -rw-r--r--1 phil phil 7704 Sep 27 06:15 versions/html2_2.pl -rw-r--r--1 phil phil 2666 Jun 6 1997 versions/html3_0.pl -rw-r--r--1 phil phil87056 Sep 17 1999 versions/html3_1.pl -rw-r--r--1 phil phil47036 Apr 13 2002 versions/html3_2.pl -rw-r--r--1 phil phil60307 Apr 13 2002 versions/html4_0.pl -rw-r--r--1 phil phil60964 Apr 13 2002 versions/html4_01.pl -rw-r--r--1 phil phil60964 Aug 21 2002 versions/html4_1.pl a) it appears that these are never used: html2_1.pl html2_2.pl html3_1.pl Correct, insofar as HTML versions 1, 2.1, and 2.2 are never used anymore, having been superseded long ago by HTML 3.2 and 4.x . Similarly 3.1 is out-dated, implementing MATH tags that never got universal acceptance. b) html4_01.pl and html4_1.pl are identical to one another. html4_01.pl is never used, because if you say `-html_version 4.01', the code rounds 4.01 to 4.0 so you get the same result as if you'd said `-html_version 4.0'. i'd guess that the idea behind html4_1.pl is to let the user say `-html_version 4.1' when they want HTML 4.01 (this doesn't quite work, because the DOCTYPE mentions 4.1). Yeah, that was the idea. OK, so there needs to be a small patch to get the DOCTYPE correct. _if_ i have all that right, then the best course of action would be to stop the code rounding 4.01 to 4.0, and delete html4_1.pl. The same trick was used with 3_1 really being 3.01 (I think). For compatibility with any existing documents or scripts calling LaTeX2HTML, it would be best to catch 4_1 and make it 4.01 where needed, as well as stopping the rounding. There is no future compatibility problem, as the W3C have effectively frozen HTML at 4.01 --- as far as I can recall. Future development is in XHTML and XML. thanks in advance for any guidance.

Re: [l2h] recycling images (?) problem
Hi Gabriele,
Hello all,
apologies if my question has an obvious answer.
I have a problem concerning what looks like a wrong image recycling.
Consider the following source, containing two xy environments:
Glad to see that you are making good use of Xy-pic.
--
\documentclass[a4paper]{article}
\usepackage{xy}
\usepackage{html}

\begin{displaymath}

p+/r2em/*+{P},**\dir{-};p=P;
P;
p+/l1em/;p+/u0.7em/;p+/d1.4em/**\dir{.};
\end{xy}
\end{displaymath}
\begin{displaymath}
\begin{xy}
1em,0em:
*+{O};
p+/u0.1em/**\dir{}?*\dir{|},
p+/d0.1em/**\dir{}?*\dir{|},
p+/r2em/*+{P},**\dir{=};p=P; %This is the only difference
P;
p+/l1em/;p+/u0.7em/;p+/d1.4em/**\dir{.};
\end{xy}
\end{displaymath}
\end{document}
--
The two environments are almost identical, but for the `double bond'
directional in the second one (marked on the snippet).
It is the almost identical that is the problem.
LaTeX2HTML constructs a key from the source code that
defines an image. This key is of finite length,
shorter than the length of your long environments.
To stay within the length limits, coding is taken from the
beginning and some from the end, disregarding some stuff
from in-between.
What is happening is that both code snippets are producing the same key,
so the recycling mechanism actually thinks that you are just reusing
the same image, so doesn't bother to handle both separately.
You could try making some trivial differences near the beginning
of the environments; e.g. with a comment
\begin{xy} % molecule with single-bond
\end{xy}
and
\begin{xy} % molecule with double-bond
\end{xy}
or put a triviality into the coding for one image:
\begin{xy}
0+0,1em,0em:
...
...
\end{xy}
Hope this helps,
Ross Moore
I translate with:
--
latex2html -split 0 \
-link 0\
-address \
-info \
-debug \
-dir /home/balducci/tmp/l2h-d \
-tmp /home/balducci/tmp/l2h-d \
source l2h-log 21
--
What I get is the first picture repeated twice.
The images.tex file contains only the first picture: the second one
does not get written to it. The generated html document sources the
same gif twice.
To me, it all works like l2h considers the two environments identical
and simply doubles the first one to avoid waste of resources (but the
two environments are NOT identical, and the double bond needs to be
there).
If I make some more evident change to the second environment, e.g.:
--
\documentclass[a4paper]{article}
\usepackage{xy}
\usepackage{html}
\begin{document}
\begin{displaymath}
\begin{xy}
1em,0em:
*+{O};
p+/u0.1em/**\dir{}?*\dir{|},
p+/d0.1em/**\dir{}?*\dir{|},
p+/r2em/*+{P},**\dir{-};p=P;
P;
p+/l1em/;p+/u0.7em/;p+/d1.4em/**\dir{.};
\end{xy}
\end{displaymath}
\begin{displaymath}
\begin{xy}
1em,0em:
*+{O};
p+/u0.1em/**\dir{}?*\dir{|},
p+/d0.1em/**\dir{}?*\dir{|},
p+/r2em/*+{P},**\dir{=};p=P; %This is the only difference
P;
p+/l1em/;p+/u0.7em/;p+/d1.4em/**\dir{.};
P; % ADDED THIS ONE
\end{xy}
\end{displaymath}
\end{document}
--
then all works properly.
Why does not l2h recognize that the two environments are different?
Am I missing something?
Could anybody check that the above behavior is reproducible?
Thank you very much in advance for any help.

Here you have so much mathematics that it belongs in a displayed
environment, yet you are trying to put it 'inline'.
Furthermore, you do not line up the = signs properly, and the lines are
cramped to be rather too close together.
Are you working in a narrow column ? Why else would you not allow your
inline math to use the full typesetting width that is available ?
but a latex2html
fails...
Yes, because LaTeX2HTML does not recognise use of \\ within inline
math as being valid markup for mathematics. It needs to be within an
environment designed for alignment and line-breaking, otherwise it will
not be recognised the way you seem to want it to be.
In the upper example all math is printed on one line (like it should be in
item 2), and this runes the whole layout of the html-document. You can see

Break it up over many smaller pages.
Some of the images have poor resolution so need to be shown much larger.
Marking-up for a web-document is generally harder than marking-up for
the printed page, since the graphics model is not so sophisticated,
and the resolution is considerably lower.

Does anyone know a work-around for this, or if it's not possable yet, you

No changes are warranted, arising from this example.

Re: [l2h] Relative URLs in png/gif images
Hi Herb,
Given the sample coding that you provided, the 'feature'
(or lack thereof) is part of the coding for the package
that now handles the way \includegraphics is processed.
However, since your image is constant, (i.e. requiring no further
processing for use in your web-pages,) then you could recode
the definition of your \showimage command,
so that LaTeX2HTML does not need to handle the image at all, but just
create the relative link. Also, it doesn't need the information
about size and spacing.
e.g.
%begin{latexonly}
\newcommand{\showpng}[4][0.9\textwidth]{%
... the same coding that you have,
ignoring the extra argument
}
%end{latex2html}
\begin{htmlonly}
\newcommand{\showpng}[4][]{%
\begin{figure}[htb]
\begin{center}
\htmladdimg[center]{#4#2}
\caption{\label{#2}#3}
\end{center}
\end{figure}
}
\end{htmlonly}
\begin{document}
I'm going to include a png image right here:
\showpng{l2h}{The figure caption}{../figs/}
\end{document}
The extra argument resolves the relative path from where
your HTML pages are placed, to where the image is located.
This is affected by Perl variables and command-line options,
so is not always easily deducible at run-time.
Hope this helps,
Ross

LaTeX2HTML uses an absolute path name when including a gif or
png image. These absolute paths will break when the entire
document is moved to a different location or a different server.
Relative URLs would be more portable and appropriate if the user
specifies an image path relative to the document.
I am using the following version of LaTeX2HTML (l2h):
This is LaTeX2HTML Version 2002 (1.67)

My test program is as follows:

\DeclareGraphicsExtensions{png}
\DeclareGraphicsRule{.png}{eps}{.bb}{`pngtopnm #1|pnmtops -noturn -rle}

\setlength{\gifwidth}{#1}
\begin{figure}[htb]
\begin{center}

\end{center}
\end{figure}
}
\begin{document}
I'm going to include a png image right here:
\showpng{l2h}{The figure caption}
\end{document}
-
The image file I'm displaying (l2h.png) and associated bounding box
(l2h.bb) are attached to this message if anyone is interested, but any
image would work just as well.
The HTML file generated by l2h specifies an absolute image URL:
I'm going to include a gif image right here:
DIV ALIGN=CENTERA NAME=l2h/AA NAME=32/A
TABLE
CAPTION ALIGN=BOTTOMSTRONGFigure 1:/STRONG

ALT=Image /h/lanhws/plano/text/www/test//l2h.png
BR
/DIV/TD/TR
/TABLE
/DIV
-
The problem may be corrected by adding a line to embed_image:
$url =~ s|^$texfilepath/*||o; # HWS: Make URLs relative
$urlimg = $url;
$urlimg =~ s/\.$IMAGE_TYPE$/.html/ if ($map);
if ($exstr =~ s/align\s*=\s*(\?)(\w+)\1($|\s|,)//io) { $align = $2; }
my $usersize = '';
-
Now the HTML uses a portable relative URL to the image, although the
ALT tag still contains an absolute URL:
I'm going to include a gif image right here:
DIV ALIGN=CENTERA NAME=l2h/AA NAME=32/A
TABLE
CAPTION ALIGN=BOTTOMSTRONGFigure 1:/STRONG

This patch will also work if the image is not in the source directory,
but in a \graphicspath directory that is relative to the source.
Another logical extension would then copy the image (wherever it is)
to the final document directory (creating the relative \graphicspath
directory, if specified) when the -local_icons switch is set.

OK, yes; it tried to make an image of the {figure} environment.
To prevent this, simply insert an empty {makeimage} environment
inside the figure; hence within your macro definition, as shown below.
This is the way to tell LaTeX2HTML to make an image just of the specified

On Sun, 6 Jul 2003, [iso-8859-2] Janusz S. Bieñ wrote:
Can latex2html accept some form of unicode (utf8 or utf16) as input?
Yes, and no.
The `no' means that there is nothing that is specifically designed
to support this kind of input.
The `yes' means that the effect of supplying UTF8 *should* be that any
bytes (nibbles?) in the upper range go through unchanged.
If this does not happen by default, then it is because the default
charsets assume that upper-8-bit characters have a special meaning that
can be translated into alternative TeX sequences, and perhaps require
an image to be created.
To stop this you may need to specify on the commandline something like:
latex2html -html_version 4.0,unicode ...other-options... filename
or
latex2html -html_version 4.0,unicode,utf8 ..
or even
latex2html -html_version 4.0,unicode,unicode ..
Basically, the problem will be that you do *not* want LaTeX2HTML
to assign special meaning to upper-8-bit codes and translate them
into something else.
Another way to prevent conversion of characters is to explicitly
kill the subroutine where such conversion occurs:
sub convert_iso_latin_chars { $_[1] }
Put the above line into your .latex2html-init file,
or other init-file for your jobs.
In short, it shouldn't be too hard to make LaTeX2HTML do what you
want, if it doesn't do so already.

Re: [l2h] About link image
Hello Egor,
On Mon, 14 Jul 2003, Egor Tur wrote:
Hi.
How can I create image one page which will be link to other html page?
And this image will be present on first page.
Use LaTeX's \label--\ref mechanism, and the \htmlref and \htmladdimg
commands from \usepackage{html}:
A. on the 2nd page, put \label{jumptohere} before the
material that you want displayed. If it's a new section,
then just put the label first:
\section{This is my stuff}\label{jumptohere}
or
\section{This is my stuff\label{jumptohere}}
B. On the first page, assuming that you have the image
as a graphic (in figures/myimage.jpg, say) put:
\htmlref{\htmladdimg{../figures/myimage.jpg}}{jumptohere}
The '../' part is needed because LaTeX2HTML builds the HTML
pages within a subdirectory, and you will need the relative
path from there to where your image is stored.
Any of the options to \htmladdimg can be used:
e.g.
\htmladdimg[width=340 height=185 align=right]{.}
Thanx.
Hope this helps,

At the moment I've been copying the non-standard files in by hand and hand editing the html. I notice that the The command line arguments were: includes a hyperlink for the *.tex file that appears to be linked to the path of the *.tex file used - this is a start but I'd really like this to be pointing to a copy of the tex file that is automatically moved into the output folder. Better is to make a symbolic link in the target directory, pointing to the source .tex file. Then make the hyperlink point at this link. That way you don't need to keep 2 files up-to-date. Also, if you want your audience to view the source files in a web-browser, then the link can have .txt as its extension, rather than .tex or .bib which most surfer's browsers will not understand as being text-only. As for automating creating of such links, this isn't really necessary, as that's a one-off thing for each job. Normally you can expect to process a LaTeX2HTML job many times, before being fully satisfied with the HTML pages, just as you would run a LaTeX job many times during development. But once the link to the sources has been created, you don't need to remake it each time. Is this possible already? Are there people working on something similar? Where should I start if I where to try to automate this? Would it make sense to build this in as a commandline option or would it be better to have a stand alone utility to run post latex2html? Thanks, James ps - In some circumstances it would be very cool to also be able to provide the style and bibliography style files - we might even be able to include anything 'pulled' in by the *.tex file. It might be a bit complicated but I'd like it to be such that anyone with a basically sane install could run the commandline specified and re-create the site.

That is definitely a lot harder; particularly since -- and --- are
rarely used correctly in LaTeX manuscripts.
So general rules may easily result in something that the author
never intended.
I'm not sure why some of the conversions in the unicode.pl file happen,
while others do not. I can't find an equivalent of the
$USE_CURLY_QUOTES in the source code that seems relevant to mdash ...
Any ideas on how to get a maximal set of the conversions in unicode.pl
actually happening? I notice that there is no do_cmd_textemdash in
unicode.pl - is that why?
Also I see from the source that converting single quotes is
tough---perhaps I'm naive but it would seem to me that this sequence
would work...
s/``/#8220;/og
s/`/#8216;/og # once the `` is gone then the ` is only used for
open single quote right?
Not at all. \` is used as an accent, and in some language variants,
the ` is made active to remove the need to use the \ .
With this active character, overloading can occur for generating
other special characters or ligatures.
s/''/#8221;/og
s/'/#8217;/og # Will also replace apostrophes with close curly
single - not a bad thing.
Sorry; I cannot agree.
Every Latin-based charset encoding has an apostrophe character.
A curly-quote is most definitely *not* logically an apostrophe, even
though it may look like one.
Try cut/paste from a web-page into LaTeX source.
Simply finding curly quotes to replace with apostrophes is *very* tedious
indeed. At least when quotes occur in pairs then you expect to have
to do something with the environment delimiters --- it should *not*
be necessary to have to search/replace apostrophes.
i.e. ensure that one does the singles after the doubles ...
But there is probably a better algorithm in the source code for 'quoter'
http://www.dwheeler.com/quoter/
The aim of an HTML translation should not be appearance.
It should be ensuring that meaning is preserved, and that no symbol
is rendered with the 'missing character' glyph.
Hope this helps,

LaTeX has a \usecounter command for this.
LaTeX2HTML is supposed to detect the presence of this *at the beginning*
in a list-environment and then use it.
Setting a counter implicitly (from enumi) at the end of one
environment to save for resetting the next, is rather counter-intuitive,
and probably will not work since this command could be executed out of
step with the list's internal counter (Perl is not LaTeX).
Certainly the action will be treated as part of an item, rather than
as a global result of the environment as a whole --- though that
may be sufficient for your purposes.
It is more logical to simply \usecounter with the same counter for each.

Hi everybody...
I have a question about the latex2html tabbing processing.
Between each line of a tabbing section, a blanked line is inserted in the HTML file
- an BR tag.
Why ??? I don't want a such space text !!!
Check the subroutine tabbing_helper .
e.g. mine is as follows:
sub tabbing_helper {
local($_) = @_;
s/\\=\s*//go; # cannot alter the tab-stops
s/\t/ /g; # convert any tabs to spaces
# MRO: replaced $* with /m
s/(^|\n)[^\n]*\\kill *\n/\n/gm;
s/( )? *\n/$1/gm; # retain at most 1 space for a \n
# replace \\ by \n ... , ignoring any trailing space
#s/ */\n/gm;
# ...but make sure successive \\ do not generate a P tag
#s/\n( *)?\n/\nnbsp;\n/gm;
s/\\\gt;//go;
s/(^| *([^\\]))\\[]/$2\t\t/go;
s/([^\\])\\/$1\t\t/go;
s/\n$//; s/^\n//; # strip off leading/trailing \n
local($inside_tabbing) = 1;
$_ = translate_commands(translate_environments($_));
PRETT\n$_\n/TT/PRE;
}
Note that 2 reg-exp replacements are commented-out (initial #).
That may be a mistake, as there seems to be nothing else
that replaces the \\ at the end of lines, so those will later
be replaced by BR as you observe.
Try uncommenting the 1st reg-exp, and perhaps both reg-exps.
This should fix the immediate problem but may introduce new problems.
Certainly there is some doubt about exactly where those lines should
be executed within the tabbing-helper subroutine.
To test changed code, you do *not* need to edit the latex2html
script itself. Put an exact copy of the subroutine code into
the .latex2html-init file for your job, and make the edits
there. Since this file is read *after* the main script, the
changed definition will override the standard one.
Report what you find please.

Yes, in LaTeX certainly that is the result of the above code-line.
Besides, I just checked the coding in LaTeX2HTML and found that
\usecounter is only recognised within an explicit {list} environment.
It would never be seen inside {enumerate}.
Mark Wooding has macros \suspend and \resume to tackle this problem in
his mdwlists package, I was just using a naive approach but some
mechanism is necessary to remember the value from one list to the
next.
Indeed; this seems to be correct.
With LaTeX2HTML, more work needs to be done with the $preitems
part of the {enumerate} environment; that is, any coding that falls
between the \begin{enumerate} and the first \item .
Currently there is no code for setting a 'start=num' attribute
to the OL tag.
Certainly this is an addition worth implementing.

I'm having problems with latex2html and the amsmath package. The
simplest example of this is for the latex file

Why do you have some equations with \htmlimage and others not ?
This should produce an html document that has four equations that look like:
x = 1 (1)
y = 2 (2)
z = 3 (3)
w = 4 (4)
No; the alignment could be shot-to-pieces by the mixture of \htmlimage
and not.
When you use \usepackage{amsmath} then LaTeX2HTML knowns to expect
lots of mathematics, perhaps with complicated alignments, and cetainly
expects to control equation-numbering.
By using \htmlimage you are saying, ignore what you would normally
do with this environment and pass it to LaTeX for an image.
This forces LaTeX2HTML to select a paper-size on which to layout
the equation and equation-number as it creates the image.
Aligning equation-numbers in images with those not in images
is essentially impossible, especially since you have no control
on how wide your reader has set his/her browser-window; that's
to say nothing of the choice of font size and style.
I don't think that is is what you want to do here at all.
In fact, that's what I get if I delete the \usepackage{amsmath}
Delete the \usepackage line ?
It's what I get if I retain that line:
http://www-texdev.ics.mq.edu.au/HALL/amseq/node1.html
statement, or don't use \htmlimage. However, what I actually get is
x = 1 (1)
y = 2 (3)
z = 3 (3)
w = 4 (5)
The .gif images are in one column of a TABLE while the non-image
equation numbers are in another column to the right of the images.
That is, the lines that use \htmlimage encode the entire equation as
a .gif (including the equation number), AND the equation number is
wrong. I would prefer that the equation number not be part of the
.gif, but more importantly, the equation numbers must be correct.
What you are asking for is supposed to be the normal behaviour
of \usepackage{amsmath}.
If that is not what you are getting, would you send a URL to a web-site
that you have created that shows it created incorrectly.
The problem with numbering get even worse for a document with sections.
Any clues on how to fix?
Certainly you should not be using \htmlimage
with environments that include numbering.

It can be due to the fact, that eqnarray and matrix has the same row

matrix is treated as another part of eqnaray. From this point all the
equation are renumbered and displayed in unproper place and order.
Are you using \usepackage{amsmath} ?
no,
Please provide example coding which does not work for you.
The example latex file is very simple:
\documentclass[12pt]{article}
\usepackage[polish]{babel}
\usepackage{t1enc}
\usepackage[latin2]{inputenc}
\usepackage[dvips]{graphicx}
\begin{document}
\selectlanguage{polish}

\sigma_x=\left( \matrix{01\cr 10}\right),
\sigma_y=\left(\matrix{0-i\cr i0}\right),
\sigma_z=\left(\matrix{10\cr 0-1}\right).
\end{eqnarray}
Ahah, you are mixing plain TeX syntax with LaTeX.
This ought to be:
\begin{eqnarray}
\sigma_x=\left( \begin{matrix}01\\ 10\end{matrix}\right)\,,\quad
\sigma_y=\left(\begin{matrix}0-i\\ i0\end{matrix}\right)\,,\quad
\sigma_z=\left(\begin{matrix}10\\ 0-1\end{matrix}\right)\,.
\end{eqnarray}
(See the result (with amsmath loaded) at:
http://www-texdev.ics.mq.edu.au/MIREK/eqntest/
)
so that LaTeX2HTML can detect the sub-environments,
and treat those separately, before parsing the {eqnarray}
But if you are using advanced mathematical structures, such
as matrices and aligned sets of equations, then you really
should be using \usepackage{amsmath}.
This allows advanced structures to be specified in a more
intuitive manner --- rather than just trying to draw pieces
on a page, expecting the resulting visual effect to carry
the intended meaning.
In LaTeX2HTML, the results for mathematics are generally
much better when {amsmath} is loaded, than when not loaded,
because the various types of alignments give a better clue
as to what kind of layout structure should be used in the HTML,
and that images are more likely to be appropriate.
\end{document}
latex2html treats it strangely, first it knows there is only one
formula, and on the other hands it tries to split the eqnarray into
several (here 3 ??) formulae.
An {eqnarray} is designed to create 3 columns in LaTeX.
You may not always choose to use all the columns, but
LaTeX2HTML will nevertheless construct a TABLE with 3 cols.
because that's the purpose of an {eqnarray}.
You have the choice of using {equation} of {displaymath}
environments, if you want a single column, with/out numbering.
If you ad some more formulae to this document you will see what will
happen. Everything gets mixed.

within the expansion of macros redefined using \renewcommand .
The reason that the behaviour with \newcommand and \renewcommand
is different is that every instance a command defined via \newcommand is
replaced very early in the processing, *before* the document is broken
into segments.
On the other hand, when \renewcommand is used, the macro is not
replaced early but instead wrapped to cause it to be replaced
in sequence with environments and other context-sensitive macros.
The difference is that if a command has been \renew'd once, then it
may well be renew'd more than once; so it cannot be assumed to have a
constant replacement throughout the whole document.
(Note that the expansion model for LaTeX2HTML differs from that
for TeX engines generally.)
How does this affect sectioning commands ?
Well, the document gets broken-up into pieces corresponding
to the recognisable sections. Then each of these sections
is processed (more or less independently) to make the individual HTML
pages. For this to work with your \ksectionalt command, you need
the replacements to have been made *before* the document is split
into pieces -- this precludes the use of \renewcommand, as explained
above.
The correct coding for what you are trying to achieve is:
\usepackage{html} % always load this with LaTeX2HTML documents
%begin{latexonly}
\newcommand{\ksectionalt}[4]{\section[#4]{#3}\chlabel{#1}\index{#2|textbf}}
%end{latexonly}
\begin{htmlonly}
\newcommand{\ksectionalt}[4]{\section{#3}}
\end{htmlonly}

Hello Roland, On Tue, 14 Oct 2003, Roland Stigge wrote: Hi, regarding the license issue, who's the current official maintainer of latex2html and/or responsible for licensing issues? I found different names: Nikos Drakos (author mentioned in LICENSE) Nikos has had nothing to do with the LaTeX2HTML software since 1996 or so. The license statement has not been changed since then. Ross Moore (extended the package) That's me; most, but not all, changes since 1998 have been through me. Marek Rouchal (also listed in docs) Marek is the contact at the physical site where the repository is located. John Turner (latex2html.org) John owns the name latex2html.org . Unfortunately, the changelogs (of the version 2002-2-1) stop at v98.1. At Debian, there are quite some latex2html bugs open [1], many of them upstream related, i.e. maybe interesting for the current primary latex2html maintainer. A few are even tagged as forwarded some years ago to this list and Ross Moore. OK; since I don't work through the Debian site, I'm not aware of these so-called 'bugs'. Any that have been reported via the latex2html mailing list have been fixed, or the mis-use explained to the poster. If that doesn't make it back to Debian, then that's my concern, sorry. Mostly the things reported as 'bugs' with use of LaTeX2HTML are due either to inadequacies in the local installation, or are in fact due to the differences in what can be achieved with HTML and other page-layout formats. The latex2html mailing list is the perfect place to get help on such issues. Now, I've just seen the current discussion on licensing, and agree with the poster who said that it is mostly just nit-picking. The wording of the statement to which you object does not, in my mind, prevent you from distributing LaTeX2HTML as a free addition to anything else. Nor does it prevent a commercial developer from using LaTeX2HTML as part of a workflow for some other software process, and charging for the other parts of that process --- including any scripts that make the calls to run LaTeX2HTML. Put differently... It is just the LaTeX2HTML distribution itself that cannot be charged-for. I would object to seeing a cost-listing that includes something like: LaTeX2HTML $200 when all that the commercial distributor has done is to include the software on a CDROM. Charging $200 for a process that installs LaTeX2HTML correctly, for use in another overall process, is not something that I would object to. However, it should be made clear to a client that this is what they are paying for, and it is up to them to decide whether or not they are getting their money's-worth. Like the GPL, the license is not meant to be an impediment to the distribution or use of the software, but just a way of ensuring that credit remains with those who did the work. I'm happy to discuss this further, but a change in the license should be discussed on the LaTeX2HTML mailing list, before any action be taken.

Imagine the extreme (yet possible) case of a distribution including just packages all of which have a license like latex2html (currently). The DFSG require the possibility of selling the aggregate software distribution. Even with your liberal interpretation, every package claims (D and B) that the fee would effectively be for the rest of the aggregation. But there's nothing left to assign that fee. Well, I'm quite happy to have a license forbid this scenario. If someone has just copied other people's software, and has not even provided installation routines, nor *anything at all* that adds value to the collection more than the sum of the free pieces, then he/she has no moral right to charge for this, apart from the 'nominal' amount mentioned previously. I'm a teacher (university lecturer) --- any student doing just this for a project would receive a failing grade. It's very close to out-and-out plagiarism, so cannot be countenanced. I find it hard to believe that Debian really regards this as an acceptable scenario, and would drop a package on that basis. To make this clearer, perhaps clause B could be extended with a similar statement about aggregations, as appears in D ? Alternatively, would it be sufficient to simply remove the adjective `nominal' ? Unfortunately, both these suggestions won't meet our requirements, IMHO. I suggest removing clause B as a whole. We (Debian) would have a problem with _both_ of the included sentences. Instead, I suggest the complete removal of clause B. That would be the final move to make latex2html DFSG-compliant. That's too much to remove; I cannot do that. Alternatively, consider the adoption of an OSI-approved license as suggested by Michael Chapman (and me, previously). Many of the files in the LaTeX2HTML distribution are already under the GPL, so it may be acceptable to Nikos to put it all under this. But then other developers would have to be contacted too. DFSG 3 states: [...] DFSG 4 states: [...] These issues were resolved by the fact that the author of floatflt.ins (Mats Dahlgren) agreed to release his file under the LPPL. They were not related to the rest of the package (see bugs.debian.org/204684). OK; that's good to hear. Feel free to change floatflt.ins in the main latex2html package accordingly. In fact floatflt.ins does not need to be distributed with LaTeX2HTML. It is no longer used in the documentation and floatflt.dtx was not also included; so it was just an oversight that the .ins file was still part of the distribution. It has now been removed from the MANIFEST. When the licensing issue is resolved (which is most important to consider for the next Debian release), I'll come back with an assorted list of bugs where I depend on your help. You are definitely not responsible for all the bugs listed at Debian.

It being at least _possible_ to charge $200 is exactly what Debian requires from Free Software. Besides the GPL, please consider the LPPL or any other free license approved at http://www.opensource.org/licenses/. I believe it is possible to do this, with an aggregation of software packages, which is all that Debian requires, right ? See above. We are not in agreement yet.

\end{document}
That is a very complicated alignment, with your inclusion of
*two* \intertext portions --- each of which contains more mathematics!
I'm pretty sure it was not the intention of the AMS LaTeX programmers
for an {align} environment to be used in this way.
Logically, you have a single paragraph, with several sentences, containing
two separate pieces of aligned mathematics. This is the kind of thing that
LaTeX2HTML expects, and it would do a good job if your manuscript was
marked-up in that way.
If you stick to simple, clear, logical markup then LaTeX2HTML will do
a good job. If you obscure your markup, then some aspects of the
translation may fail, or you may get HTML coding that is not the most
desirable for the information that you are wishing to present.
So my first piece of advice is to *simplify* your coding.
e.g.
Do *not* try to be cute by having some environments align with
others --- that's a layout issue, rather that a logical structure
issue; besides, the journal editor may not like that effect,
which may not even work properly anyway (e.g. in multiple-columns).
Secondly, if you are going to ignore the above advice, (as you are
entitled to do), then at least follow very closely to printed
examples that create the effects you desire...
The last =1-\frac{\hat v}{(\pi/4)^2} part is not aligned on the
'=' as the other sections of the are.
... by including \\ to end the alignment row before the \intertext
command. (You do this in the first instance, but not the second.)
This should give a result like what you can see at:
http://www-texdev.ics.mq.edu.au/MARTIN/aligntest/
In LaTeX, the spacing is unaffected:
http://www-texdev.ics.mq.edu.au/MARTIN/aligntest.pdf
(In this PDF you can see also many other subtle differences from your
coding, which contribute to making the complicated mathematical
expressions easier to read and understand.
For the source that I used, get aligntest.tex in the same directory.)
$HTML_VERSION = '3.2,math';
in the l2hinit file.
This latex file renders properly under Miktex.
LaTeX (via MikTeX) is building up an image of a page for itself.
LaTeX2HTML is trying to encode the structure of your information
to present in a logical way to (many different) web-browsers, so that
they can build their own idea of how the page should appear.
That is a quite different problem, which in some senses is more
difficult. The hints as to the logical structure must come from the
markup commands that you use in the LaTeX source of your document.
If you use convoluted LaTeX coding constructions, then you are less
likely to get the result that you think you want.
Thank you.
Hope this helps,

Re: [l2h] tableofcontents UL type

Hi,

a.. 1.1.1 Chemometrics: an example
b.. 1.1.2 Chemometrics data matrices
c.. 1.1.3 Calibration and test problems

Is there a way to avoid the discs (bullets) in front of each line of the toc
?? I can think of one way: to post-process my html-document using a
perl-script and modify the toc UL's using a CSS class. But is there a easier
way?
That certainly should work.
It's easiest if you have $USE_STYLES set (automatic with HTML 4.0 and
later, but this is not set with the standard default of HTML 3.2),
for the laTeX2HTML inserts the attribute:CLASS=ChildLinks
as has been mentioned already on this list.
Post-processing to search for this string and extend it:
e.g. to CLASS=ChildLinks TYPE=square
should be quite easy to do.
You could even add a line of Perl coding to an initialisation file,
defining: sub post_post_process
to do a regular-expression search and replace.
This will then cause LaTeX2HTML to do the post-processing for you.
Alternatively, you could have LaTeX2HTML use a different set of
attributes from the outset. For this you will need to know that
the coding that controls this is within the subroutine:
add_real_child_links
within the main latex2html script.
You should be able to find the lines:
$list_class = ' CLASS=ChildLinks' if ($USING_STYLES);
$startlist = UL$list_class unless $CHILD_NOLIST;
You could then simply alter the first line to read something like:
$list_class = ' CLASS=ChildLinks TYPE=square';
If you do this, then you should copy the *entire* subroutine block
sub add_real_child_links { . }
into an initialisation file and make the changes there.
Best,

Hi again Bill,
On Sat, 1 Nov 2003, William Martin wrote:
I have been reading the Latex Web Companion very closely. I haven't
quite figured out out to use CSS styles, but I am really close. Is this
valid?:

OK; I was intending to answer this question, that you posted
earlier --- last week, wasn't it ?
So this message is going to the latex2html email list too.
There are several problems here.
Firstly, the syntax is:
\htmlsetstyle[UL]{junk}{list-style-type=square;
as the CLASS is 'junk' which need not qualify anything,
though in this case you want it for UL.junk .
That will write the rule into the .css file...
Secondly.
... *provided* you delete or rename the existing one.
That is, you must *force* LaTeX2HTML to write out the information.
If a CSS file of the correct name already exists, then a new one is
*not* created. This is a rather crude way of not writing .css files
which generally do not change often.
Thirdly,
\begin{document}
\begin[junk.UL]{itemize}
this should be \begin[junk]{itemize}
as the UL is implicit in the kind of environment being processed.
However, for some reason the 'CLASS=junk' isn't being
applied to the list tagging in the HTML output.
I'll need to diagnose why not.
Fourthly,
This will not write to .css properly:
list-style-image=url(http://www.orie.cornell.edu/redcircle.jpg)}
^
since the ':' is interpreted as a delimiter of CSS properties.
I guess the correct logic is to treat the '(' and ')' as delimiters
that bind more tightly, cancelling the special interpretation of ':'.
This means adding a line of Perl coding to the subroutine:
sub process_htmlstyles .
to revert some replacements ( ':' -- ' : ' ) made earlier,
or to rethink this processing altogether.
\item item1
\item item2
\item item3
\end{itemize}
\end{document}
The resulting UL stuff does not contain any tag information.
Thanks for the reports.
Clearly more work is needed to make use of CSS styles more robust.

Yes; the requested level of HTML output affects what LaTeX2HTML produces,

With lots of mathematics, including aligned environments, it's often
best to use larger images rather than lots of smaller images.

However, the non-local nature of the processing in LaTeX2HTML means that
separate methods are needed in Perl to implement them properly.
Thus you may need to be a bit more careful with how the preamble is setup.

thing that doesn't work the way i'd like is that each (included) comment
environment is turned into an image: they're perfectly good images, but
images weren't necessary, simple HTML could have done the job. is this
what you expect latex2html to do? is it difficult to stop it doing it?
Your code below simply says to include/exclude the environments.
It doesn't say how to translate their contents; that's why you get
the images.
You still need a \newenvironment definition, even if it
doesn't do much; e.g.
\begin{htmlonly}
\newenvironment{versionpub}{\begin{flushleft}}{\end{flushleft}}
\newenvironment{versionpriv}{\begin{flushleft}}{\end{flushleft}}
\end{htmlonly}
or
\begin{htmlonly}
\newenvironment{versionpub}{}{}
\newenvironment{versionpriv}{}{}
\end{htmlonly}
The \begin{htmlonly}...\end{htmlonly} restricts this
definition to processing by LaTeX2HTML, in case there
is already a sensible definition for LaTeX.
a minimal example:
= start =
\documentclass[a4paper]{article}
\usepackage{html}
\includecomment{versionpriv}
\excludecomment{versionpub}
%\includecomment{versionpub}
%\excludecomment{versionpriv}
\begin{document}
\begin{versionpriv}Secret info
\end{versionpriv}
\begin{versionpub}[Omitted from online version]
\end{versionpub}
\end{document}
== end ==
to the original poster: if you're seeing different problems, please go
ahead and post your own example.
Hmm; it seems that LaTeX doesn't need a separate definition for the
environment. It wasn't implemented that way for LaTeX2HTML.
I think that it is better to retain delimiters for such environments,
to that extra HTML markup can be added, if desired.
Hope this helps,
Ross

LaTeX2HTML has various mechanisms for applying graphics effects

Alternatively, you can try simple things like:
$\displaystyle \sigma =\frac{F_r}{A_o}$
or
\mbox{\scalebox{1.5}{$\sigma =\frac{F_r}{A_o}$}}
or
\(\scalebox{1.5}{$\sigma =\frac{F_r}{A_o}$\)
to get the enlarged size captured within an image.
The question must be asked of why are you using \scalebox{1.5}
with inline mathematics ?
How does this add to the meaning to be conveyed by your manuscript?
If it is simply that the \frac is too small, then you should be
using \displaystyle, or \dfrac (from amsmath.sty).
anyone can fix this?

Yes; no further philosophical discussion should be needed at this stage.
But in our bug tracking system there are some issues left, most of which
disappeared at the latest with the 2002-2-1 version of LaTeX2HTML.
Nevertheless, some of them are possibly interesting for this list and I
intend to discuss them here one by another.
First, please have a look at
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=72755
I've had a look at this, and do not regard any of them
(except some aspects of the 1st) as actual bugs.
Rather, the person who wrote the message is making assumptions,
leading to wishingful-thinking about features which are not
implemented.
I can reproduce all of the described problems with LaTeX2HTML 2002-2-1.
Here's a reproduction of the message:
Hi!
1. When using \HTMLsetenv{MAX_SPLIT_DEPTH}{0} in a TeX file latex2html
should put all its html output into one single document. But it does
not. Footnotes are still in extra documents. Furthermore, body tags, set
with \bodytext, are ignored in this case!
The \HTMLsetenv command is intended for setting values of Perl variables,
as an aid to storing information to be used later within a document.
While it *can* change variables concerning the global structure of the
website, this is not its intended use.
Indeed, if you try this with configuration parameters, then there is no
guarantee that there will be any effect at all; or if there is an effect,
then it may not be what you would like it to be.
There is nothing in the LaTeX2HTML documentation that suggests using
\HTMLset or \HTMLsetenv is a substitute for command-line parameters,
or setting values within initialisation files.
The simple explanation, in most cases, is that by the time Perl is
processing the contents of a document, the value of the particular
configuration variable may have been read already, and acted upon.
Subsequent changes have no effect because that particular parameter
is not used again.
(Basically, the timing is just wrong.)
In the case of $MAX_SPLIT_DEPTH, you *can* change the split-level
after document-processing has started, but not necessarily at all
possible levels of splitting. And if you change it several times
throughout the document, then the Table-of-Contents and mini-TOCs
may not be built correctly, since these are done at the end,
using the value of $MAX_SPLIT_DEPTH at that time.
Also, it's not overly surprising that setting the value to 0
does not result in all the content on one HTML page,
because certain actions regarding splitting will have been
performed before processing of the document is underway.
When using the command line argument -split 0 instead of \HTMLsetenv
latex2html works in the correct way, also \bodytext is o.k.
2. When using \HTMLsetenv{NO_SUBDIR}{1} in a TeX file, this command has
no effect. latex2html should put all generated files in the current
directory in this case.
This one *definitely* cannot be changed within the job being processed.
The file location has already been chosen by that time, and some
helper files have been written already.
Again, when using the command line argument -no_subdir everything is
fine.
3. When using \HTMLsetenv{INFO}{} or \HTMLsetenv{INFO}{0} there is no
document info (or 0 resp.) but the About this document... header
still appears in the output document. But there should be nothing!
A marker to determine the position of the INFO page is placed early
in the processing, though the page itself is not generated until later.
Perhaps the variable $INFO is not checked again, after this.
I'll take this message as a request to be able to cancel the INFO page
from within the LaTeX source --- that should be possible to program,
rather easily.
Once again, when using the command line argument -info or -info 0
everything is o.k.
Yes; the command-line arguments, or Perl coding within initialisation
files (e.g. using -init_file file as a command-line switch)
are the recommended ways to adjust non-content aspects of the HTML site
produced by LaTeX2HTML.

Re: [l2h] avoiding conversion of -- to -
Hi Fred,
On Wed, 17 Dec 2003, Fred L. Drake, Jr. wrote:
I'm using LaTeX2HTML to convert programmer's API documentation using a
fair bit of custom Perl code.
Over the years, I've dealt with many places in our documentation where
the text -- is contained as content rather than an markup for an
en-dash. In each case, I've avoided the en-dash conversion by adding
still more markup in the document text. While less than ideal, it has
worked.
I recently decided it was time to tackle this problem in a more
general way.
In each case where I've needed to deal with this conversion, the
affected -- has occurred in content which is known to never need the
conversion based on the surrounding markup. What I've tried to do in
these cases is to convert the -- to some other HTML spelling of
those two characters; I've tried both -#45; and the XHTML-ish
-#x2d;. In both cases, the conversion still takes place.
Where in LaTeX2HTML is this conversion being done? Is there some way
to suppress this without an uglier transformation of the --?
It happens in the text_cleanup routine:
# This routine must be called once on the text only,
# else it will eat up sensitive constructs.
sub text_cleanup {
# MRO: replaced $* with /m
s/(\s*\n){3,}/\n\n/gom; # Replace consecutive blank lines with one
s/(\/?)P\s*(\w)/$1P\n$2/gom; # clean up paragraph starts and ends
s/$O\d+$C//go; # Get rid of bracket id's
s/$OP\d+$CP//go;# Get rid of processed bracket id's
s/(!)?--?()?/(length($1) || length($2)) ? $1--$2 : -/ge;
_^^___^
here's the pattern!
HTML comment delimiters pass unchanged
other occurrences of -- are contracted
I will note that converting -- to -span-/span or
-!--junk--- works, but both are incredibly ugly ways of doing
this.
Sure.
I'd suggest that you replace the above line by a subroutine call,
then define the subroutine to do whatever replacements you think
are best for you -- perhaps none at all.
Theoretically, this replacement line is wrong, since it occurs
on 'output' rather than on 'input', as it would do with a TeX engine.
But I cannot find a better place for it, since it needs to act on the
result of macro expansions, as well as the normal text of the document.
Currently the replacement acts *after* all macro expansions have been
done, and all environments have been processed, but *before* verbatim
strings (and other 'sensitive' marked constructs) are re-inserted into
the document.
You say...

So perhaps you should be using a construct that creates a 'sensitive'
marker for the whole block of content, in a similar way to how
verbatim-like environments are handled. (These have their content
stored in a database, and a 'marker' inserted into the document;
to be replaced much later by the replace_sensitive_markers routine.)
However, environments like {alltt} cannot be done this way, as for
those macros still need to be expanded.
Any further ideas would be welcome.

Re: [l2h] alignmentproblem eqnarray - amsmath - test-case
Hi Peter,
On Tue, 30 Dec 2003, Peter Morling wrote:
Dear Ross,
here is a testcase of the problems.
Thanks for these.
Now I see what is the problem:
where to put the extra white-space, of undetermined amount.
(In TeX this is done using \hfill.)
1. first with AMSMATH
http://www.statmaster.sdu.dk/maskel/docs/eqnarray/withAMSMATH/index.html
2. without AMSMATH
http://www.statmaster.sdu.dk/maskel/docs/eqnarray/withoutAMSMATH/index.html
The reason that these are different when there is no numbering,
is that #2 uses a single image, which is then centered.
non-AMSMATH creates what I call 'novice'-mode mathematics HTML.
That is, very little mathematics is expected in the document,
so whatever there is causes a single large image to be generated,
whenever this is adequate.
with AMSMATH it is expected that more mathematics will occur,
and with greater use of alignments --- 'professional'-mode.
Here alignments are parsed, and images made of the cells.
'expert'-mode takes the parsing even further:
cell contents are parsed, making images only when needed
to construct something complicated; e.g. fractions, \sqrt{...},
special symbols, etc.
This usually results in many more but smaller images, which are
reused throughout the HTML of the document.
(It requires command-line switches, or an init-file setting
to get 'expert'-mode mathematics to be generated.)
Note that expert-mode is a prelude to generating MathML coding
for mathematical expressions. It has long been an aim of mine
to develop a MathML module for use with LaTeX2HTML.
After a bit of experimentation, I can now see how to get the
'proper' centering. The HTML needs to have:
td width=50% .
^^
for the left and right cells of the mathematics in the alignment
TABLE. (The eqn-number cells remain as fixed-width.)
It should be quite easy to adjust the LaTeX2HTML coding to add these
extra width attributes.
You can expect another email soon, telling you the required edits;
It will take a bit longer before the repository is updated at
www.latex2html.org
as I'm planning to submit many more changes than just these.
Best,
Peter

Hello,

Are you recording some of these names as constants, then creating
hyperlinks to them ? That's not a recommended technique.
Instead you should use LaTeX's symbolic \label--\ref mechanism,
which assigns your own choice of name for anchor targets.
Either syntax should work:
\subsection{... subsection name ...\label{..label...}}
\subsection{... subsection name ...}\label{..label...}
creating an anchor that immediately precedes the subsection title,
so that hyperlinks jump to the window location that has the title
at the top.
of the subsections and subsubsections as anchor names. I'm aware that
this causes trouble if a heading appears more than once within one html
file, but this is not a problem in our case. It's important that the
mnemonic anchors are the ones which are actually used in the document
(for example in the table of contents). How can this be achieved?
You will have to explain to me why this is necessary, for a single site.
It sounds like you have a complicated site which is not always updated
as a single unit, and want some parts to link into others.
The labels.pl file is designed for this.
It gives you perl-coding for the \label commands used within one
document, so that they can be referenced from another.
This is the basis of the \externalref mechanism, using
the \externallabels command.

Let's say in section 8 you add a new subsection foo at the beginning

points to foo. This is what I want to avoid.
I assume (and this has proven to be true) that most users actually copy
the link out of the table of contents or the listing of sub(sub)sections

talking about links within the document, but links from outside to the

OK; so it's meant as a convenience in non-LaTeX2HTML situations.
Are you recording some of these names as constants, then creating
hyperlinks to them ? That's not a recommended technique.
Yet this is indeed what you want to allow.
OK, that needs some thought.
Instead you should use LaTeX's symbolic \label--\ref mechanism,
which assigns your own choice of name for anchor targets.
Either syntax should work:
\subsection{... subsection name ...\label{..label...}}
\subsection{... subsection name ...}\label{..label...}
creating an anchor that immediately precedes the subsection title,
so that hyperlinks jump to the window location that has the title
at the top.
Actually I can do this, but most users won't see this link, because they
copypaste the link from the TOC and the listing of sub(sub)sections at
True. That \label is pretty-much only used when you make an explicit
\ref (or \hyperref or similar) to it from withhin the body of the
document.
It is *not* used in the structure of the document's web-site.

the links in the TOC stay the same like before if I use the technique
above.)
Nope; not at present.
Though this is probably what we want.
There should be a hierarchy of choices for the label to use
when building the TOC and mini-TOCs:
a. use a symbolic \label if there is one
else
b. construct a label from the section-title;
use this, if it is unique for the HTML-page
else
c. use the current label based on the section-numbers.
This should be possible to do; but a full solution will take some time
to develop.
of the subsections and subsubsections as anchor names. I'm aware that
this causes trouble if a heading appears more than once within one html
file, but this is not a problem in our case. It's important that the
mnemonic anchors are the ones which are actually used in the document
(for example in the table of contents). How can this be achieved?
You will have to explain to me why this is necessary, for a single site.
It sounds like you have a complicated site which is not always updated
as a single unit, and want some parts to link into others.
I already tried to explain it above. Links within the document are not a
problem.
I hope the problem is now clearer.
Yes, it is.
Do my comments above agree with your own thoughts ?

I've already done so for HTML 4.0 and 4.01
( -html_version 4.1 gives 4.01 )
Did you get my email where I discussed what is valid according
to the HTML recommendations ?
HTML 3.2 does *not* allow width=50% in th and td tags.

My nsgmls validator complains about these with 3.2, but not with 4.x.
(Browsers, however, will still recognise them, since they do not
seem to care about the DTD that has been specified.)
So I don't want to change the coding for LaTeX2HTML when generating
HTML 3.2.
But that doesn't stop you, either:
1. editing your own installed copy of /versions/html3_2.pl
(' width=\50%\' needs to be inserted in 3 places only!)
OR
2. within an init-file, putting an edited copy of the code-block
for the subroutine do_env_eqnarray , and use this for all
of your critical jobs that benefit from this.
I think it is useful for LaTeX2HTML to continue producing, by default,
coding that is valid against the stated DTD.
(Though for ease of generating output that corresponds with TeX
expectations yet is not overly complicated to read, this DTD need not
be the 'strict' version of the W3C's HTML recommendations).
Yet it should remain easy for authors to deviate from this path,
should they choose to do so --- perhaps without even knowing it.

Re: [l2h] tex counters cannot be used in html 4.0 for programming latex2html
Hi again Peter,
On Fri, 2 Jan 2004, Peter Morling wrote:
Dear Ross,
another problem occoured using html 4.0. Everytime you refer to a counter it
will be tagged with:
SPAN CLASS=arabic \thecounter /SPAN
...meaning you cannot use LaTeX counters for your own anchors!
e.g.,
\newcommand{\ltopanchor}{
\rawhtml
!-- Start of topanchor --
A NAME=SEC\endrawhtml\thesection\rawhtml
!-- End of topanchor --
\endrawhtml
}
In LaTeX \thesection gives a formatted representation of the value
of the counter. It is *not* the numerical value of the counter.
For example, in chapter 3 of a book, \thesection might give 3.2
whereas the value of the counter is just 2 .
To get the number itself, use:
\value{section}
In TeX, this will give you the internal (binary) representation
of the number, useful for calculations, or for passing to formatting
macros: e.g.
\number{\value{section}}
In LaTeX2HTML, either of \value{section} or \number{\value{section}}
should give the correct string, since Perl passes all (touchwood) data
around as strings, or pointers to strings.
will produce in html 4.0
!-- Start of topanchor --
A NAME=SECSPAN CLASS=arabic1/SPAN.SPAN CLASS=arabic0/SPAN
!-- End of topanchor --
Yes; you're pretty much on your own, when you play with rawhtml .
There's no guarantee of validity, or even correctness, when you
work with that.
You may find it easier to use \HTMLcode to construct raw HTML,
using information from the document-body:
\HTMLcode[name=SEC\value{section}.\value{subsection}]{A}
in html 3.2 everything works fine and will produce:
!-- Start of topanchor --
A NAME=SEC1.0
!-- End of topanchor --
Just lucky, I guess. :-)
HTML 4.0 is more complicated that 3.2, since you are *expected*
to use CSS styles --- much more so than with HTML 3.2.
Is there a solution to this problem? (except for post-processing html for
the excact span-tag ;) )
Try using \value{counter} rather than \thecounter .
Or try
\renewcommand{\thesection}{\number{\value{section}}.\number{\value{subsection}}}
--- though this will affect the display within the body of your document
as well as in these artificially constructed NAME attributes.
Just to check my statements above are correct, from the latex2html script
we have the following Perl coding:
sub do_cmd_value {
... read the arguments correctly ...
$val = get_counter_value($ctr);
if ($val) { $val.$_ }
else { join('', 0,$_) }
}
sub do_cmd_arabic {
local($ctr, $val, $id, $_) = read_counter_value($_[0]);
$val = ($val ? farabic($val) : 0);
styled_number_text('arabic', $val, $id);
}
where
sub read_counter_value {
... read the arguments correctly ...
$val = get_counter_value($ctr);
($ctr, $val, $br_id, $_)
}
So, the effective difference lies in the use of
styled_number_text for the output value from the counter.
sub styled_number_text {
local($num_style, $val, $txtID) = @_;
if ($USING_STYLES) {
$txt_style{$num_style} = unless ($txt_style{$num_style});
join('',SPAN CLASS=\$num_style\, $val, /SPAN, $_);
} else { $val.$_ }
}
With HTML3.2, the $USING_STYLES parameter is unset by default,
whereas with HTML4.0 it *is* set.
(You can turn it off, if you wish, in an init-file.)
Best,
Peter
Hopefully this makes it clear what options are available to you.
(There are many, at all levels: (La)TeX, Perl, HTML/CSS .)

The alignment in these was fine in Netscape, until they recently changed

As for IE, they have an interpretation which is quite different, and

Without the amsmath package, there is no problem, the equation in not split

You can get the single image, using \htmlimage{...} within the

Alternatively, try the -no_math and -no_math_parsing switches, to affect
the extent to which math-environments are parsed.

Ross Moore wrote:
Hello John,
Please send an example where this has failed for you.
Thanks Ross for your incredibly speedy response.
In comparison, I have been a little tardy in setting up the website.
I've looked at the examples, thanks.
As I thought, the problem was rather subtle:
The \providecommand replacement of \tabularnewline was not
taking place, when the document has sections --- unless the table
occurs *before* the first \section (or \chapter, etc.) command.
Following the logic of the command-replacement coding, it became
apparent that a Perl variable $within_preamble was not being
reset to 0 after the first sectioned-segment of the full document;
i.e., after the preamble has been fully processed, for documents
containing multiple (sub-)sections, etc.
The value of $within_preamble only affects the handling of macros
defined using \providecommand, and for which there is no
\renewcommand definition also. (It's used to indicate the need to
put the \providecommand line itself into the preamble constructed
for generating images.)
Also, if the macro was expanding into ordinary text, then there
would probably not have been a noticeable problem, as the replacement
would then have taken place later in the processing.
However, since the intended expansion is \tabularnewline -- \\
to create the delimiter for table rows, your example produces
something rather unexpected --- but explainable.
In fact, you would get the same result if you replace all
(in fact, the first is enough) instances of \tabularnewline
by \newline .
So here's a simple fix, which I'm rather confident is robust,
and will be included in the next update of LaTeX2HTML.
In the latex2html script (any version, so I won't give line
numbers),
find the following code portion, and insert the indicated lines:
} else { push(@pieces, $this_cmd) }
}
push(@pieces, $after);
INSERT the next 2 lines:
# after the first segment we should no longer be in the
preamble.
$within_preamble = 0;
end of INSERT
}
print $replacements new-command replacements\n
if (($VERBOSITY1) $replacements);
# recombine the processed pieces
Go to http://www.og.co.nz and follow the aubit4gl link.
I have agreed to do the documentation for the Aubit 4GL project.
I have put 3 triplets there based on table.lyx and badtable.lyx.
The generated .tex and html trees are href'd on that page.
These are the minimal examples of a good and a bad table. For me it
seems that putting a table after any section or subsection causes the
problem. Note that I am using -split 3 -link 4 in order to get a node
for each section with a toc at the top of the page.
The aubit file above are also big examples of the problem (the pdf is
good, the htmls have only the 1st row of tables int them.
Yes. When LaTeX2HTML finds excess cells in a line, they are omitted
altogether.
This is better than trying to guess the correct structure of a table,
because HTML browser do really weird, unfriendly things with incomplete
and badly-formed tables.
However, there should be a warning message that something is wrong;
so I'll look into adding that for future releases.
Happy hunting!
Thanks for the bug report.
That was a rather special combination of circumstances
which had not been anticipated, hence went untested,
when devising the support for \providecommand .

Hello,
I got rid of some of the problems with the image
processing my self:
Conclusion:
Image conversion/scaling of images works fine on win
XP as long as:
1) The .tex and the image files are on the same
partition
2) one specifies relative paths i.e. without using the
drive letter in the Latex include graphics command.
3) have a file extension in the include graphics
command.
There is a very peculiar thing when the full path
including drive letter is used in the \includegraphics
command, e.g.
\includegraphics[clip,scale=0.2]{c:/path_to_image/image.jpg}
When your image is a .jpg , and its not so large as to be
prohibitive to view via the web, then you don't actually
need to use \includegraphics .
The \htmladdimg command, from html.sty , is often a better
command to use. You can specify size and alignment for
the way the picture is to be shown in your HTML pages,
quite independently of how the image is handled in a typeset
LaTeX version of your document.
No processing at all is done on the image, so nothing
can go wrong.
%begin{latexonly}
\includegraphics[clip,scale=0.2]{c:/path_to_image/image}
%end{latexonly}
\htmladdimg[align=right width=400 height=300]
{rel_path_to_image/image.jpg}
where the rel_path_to_image needs to be relative to where
the HTML page will ultimately be located.
(e.g. .. if the image is in the same directory as the
source and you are just using default locations.)
then the resulting image is not scaled but resized by
L2H to the size specified in the image.bb and
resized image is in grayscale, whereas as the original
was in color.
If there is a platform-specific problem, then just use
\htmladdimg to avoid it.
In the case the tex source and the image files are on
separate partitions, maybe the variable $GRAPHICS_PATH
that could be set to take care of the problem?
If you are using a \graphicspath command in your LaTeX source,
then this could help find a .eps version of your image.
Afterall, it is just normal LaTeX processing that is taking
place when you use LaTeX+dvips+Ghostscript to resample the
image from an \includegraphics command.
see the previous mention thread on
gmane.editors.lyx.general

So, inline equation is not aligned on the baseline of the text

The math latex code is ... $3 \times 3$ matrices... which has no
lower part.
While setting up a simplified example file, I tested it with Netscape
4.8
instead of my usual browser (Mozilla 1.5). Alignment is OK, but
the grey background is visible.
In fact one of the reasons to shift to Mozilla is that it could deal
correctly
with transparent png, but it clearly does not understand
the align=MIDDLE alignment directive in the tag.
Yes. That is a known, and now acknowledged, bug in Mozilla, according to
what I've been told.
Is this a known problem ? Did I miss something in the preferences ?
Is it Solaris-Sparc specific ?
No. Some time ago the Mozilla developers mistakenly thought that
it would be good to copy the buggy way that M$ IE aligns images inline.
That method makes it impossible to reliably align using middle
when the text is allowed to flow with changing window-size.
So this seems also an issue for the browser point of view:
- with Netscape 4.8, the alignment is correct, but the grey background
of the png is visible (I would like to stick to png);
- with Mozilla 1.5, the aligment is uncorrect, but the transparency of
the png is correct.
It has taking some convincing to get them to acknowledge the error.
Hopefully a newer version will have both correct alignment,
and full support for PNG images.
As the original code and the two snaphots are quite small,
I think I may attach them, I've added a second inline with a lower
part.
[snip: patch to control use of .t02 file with a Perl variable]
Thanks a lot for this patch, I will check if it is OK for the
whole document in question, which has a lot of inline math.
If I understand correctly how the code works, it is normal to
have extra space below because it allows to get a correct alignment
Yes; that is correct.
Sometimes a small amount can safely be shaved off;
e.g. at the bottom of {\cal S} which drops a little
below the baseline, but doesn't warrant align=middle
because of this.
It is because of things like {\cal S}, and other script letters,
that a small gap is always inserted below the baseline.
If no more than 3 rows of white can be shaved, then this is deemed
to be OK, and simply removes that extra bit --- a good thing.
Then the shaved image is used, with align=bottom.
However, if the 'shaving' removes too much, as in your example,
then the image is correct already and needs align=middle .
of the formulas with align=MIDDLE. Thus I guess that forcing cropping
may solve the particular problem I mentioned, but may make worse
other formulas (with integrals e.g.).
Yes, indeed that will happen.
The current mechanism is as good as can be done; assuming:
a. the browser aligns correctly
b. you don't want to go to the trouble of specifically
locating every paragraph, line and image on the HTML page,
and specifying all the font sizes and line-heights.
I'll keep the list posted on this.
Regards, and thanks agian for investigating the code.
I'm glad you found it readable and/or understandable.
It's good to have people out there who can hack at the
coding. But please don't distribute this particular hack,
because it will actually create some more problems that
are very hard to solve.
Hope this helps,

Re: [l2h] newbie, problem with \url + lyx

Hello!
Sorry to disturb you with this again, but i found this in the l2h web
archive and have a question for this:
You wrote on Wed, 13 Sep 2000 09:58:44 +1100 (EST):
There is no name clash in LaTeX, because e.g.
\begin_inset LatexCommand \htmlurl[LyX]{http://www.lyx.org/}
\end_inset
is translated as:
\IfFileExists{url.sty}{\usepackage{url}}
{\newcommand{\url}{\texttt}}
in the preamble (to cope with (La)TeX installation not knowing about
url.sty),
and:
LyX \url{http://www.lyx.org/}
in the LaTeX code.
Well, i'm just about having the same problem. I use LyX-1.3.4 and
latex2html-2002.2.1_2 here, and want to define URLs in a lyx file to
convert into html.
I find the above translated line in the tex file, but it seems that
latex2html doesn't know about \IfFileExists{} and so doesn't load
the url.sty and therefore the URLs are not generated.
Have you loaded html.sty ?
This is vital for proper use of hyperlinks with LaTeX2HTML,
since it
a. causes certain markup to be recognised in the LaTeX source
b. loads the translation modules for hyperlinking constructions
and features to be used with the document translation.
This includes defining \url and \htmlurl to do the
right thing, so that it is not necessary to load other packages.
*All* documents that make significant use of hyperlinking
should \usepackage{html} when being translated into HTML
using LaTeX2HTML.
That is a general rule for which there are no real exceptions,
in normal LaTeX usage.
If i export the LyX file into LaTeX and try to convert the LaTeX
file into html, i get the following eror:
Unknown commands: IfFileExists
Yes. \IfFileExists is a programming construction, which implies
that programming code (which LaTeX2HTML probably cannot deal with)
is about to be loaded.
LaTeX2HTML interprets markup; it does not execute arbitrary
(La)TeX programming code.
If i remove the if routine and put a plain \usepackage{url} into it,
the error sounds like this:
No implementation found for style `url'
though the url.sty is present (comes with latex2html in texinputs
subdir).
With html.sty there is no need for loading url.sty separately.
It has nothing to add that isn't already handled by LaTeX2HTML.
Do you have any idea where the problem might be?
Is there in fact a problem in the HTML that is generated ?
If not, then just ignore these warning messages.
If there are problems in the translation, or you really want to
suppress the warnings, then try starting your document as follows:
\documentclass..
\usepackage{html}
%begin{latexonly}
\IfFileExists{url.sty}{\usepackage{url}}
{\newcommand{\url}{\texttt}}
%end{latexonly}
Those special comments do not change the result when processing
with any TeX-based software, such as LaTeX or pdflatex or lyx,
but tell the Perl-based LaTeX2HTML to ignore the coding in-between.
Hope this helps,
Ross Moore

Well, and there's my question... i managed to manually change the

don't want to do that manually everytime, so my question was more
Is it really that hard to add a few lines to your LaTeX jobs ?
You could write a short script that does it for you.
LyX related... why doesn't lyx do what you suggest?
LyX and LaTeX2HTML were developed independently,
perhaps with different aims in mind.
Since LaTeX2HTML has been around longer, your question
is best addressed to the LyX development team.
LyX does add the already mentioned \usepackage{url} and after
converting it with LaTeX there's the already mentioned
IfFileExists{} routine in it.
So i assume there's a mistake either in LyX or in latex.
Not at all.
The url.sty package is a graft of the URL concept into
TeX --- which was devised long before the internet was
even conceived.
On the other hand, the URL idea was well-known when
LaTeX2HTML was developed, so is fully incorporated into
its design (and perhaps similarly for LyX).
However, since many LaTeX documents were already
in existence (and continue to be written) without reference
to hyperlinking, then it is quite understandable that
a package needs to be loaded to allow hyperlinking markup
to be properly interpreted.
For LaTeX2HTML this is html.sty --- which does all that
is done by url.sty plus a lot more.
LyX chooses to just use url.sty .
(It could choose to use either html.sty or hyperref.sty
as more sophisticated alternatives; each of these loads
url.sty as part of the extra features that are offered.)
If you use LyX to write your LaTeX documents, there is
no a priori reason why it should know that you intend
to also process your documents with LaTeX2HTML.
That is your choice, and you should be prepared to
adjust your manuscripts appropriately, or ...
Is there in fact a problem in the HTML that is generated ?
If not, then just ignore these warning messages.
If i builld it manually, the resulting HTML works, well. When trying
to get the same results with using the LyX internal export feature,
it doesn't.
... ask the LyX team to implement better compatibility
for subsequent processing with LaTeX2HTML.
\documentclass..
\usepackage{html}
%begin{latexonly}
\IfFileExists{url.sty}{\usepackage{url}}
{\newcommand{\url}{\texttt}}
%end{latexonly}
Those special comments do not change the result when processing
with any TeX-based software, such as LaTeX or pdflatex or lyx,
but tell the Perl-based LaTeX2HTML to ignore the coding in-between.
How do i add them to work in the automated LyX processing?
If you are using the LyX interface to compose your LaTeX
manuscripts, then that is a question for the LyX team to answer.

Hope this helps,

Re: [l2h] latex2html bug report when handling TEXINPUTS.
Hi Erling,
On 23/04/2004, at 10:09 PM, Erling D. Andersen wrote:
Hi

and it seems latex2html does not feed it properly to texpand.
No; it's not supposed to.
You are expected to supply a Perl definition to $TEXINPUTS
within a local .latex2html-init file.
If you change the code from
L2hos-syswait($TEXEXPAND $dbg -auto_exclude $unseg
. -save_styles $DESTDIR$dd$TMP_${dd}styles
. ($TEXINPUTS ? -texinputs $TEXINPUTS : '' )
. (($VERBOSITY 2) ? -verbose : '' )
. -out $DESTDIR$dd$TMP_$dd$FILE
. $texfilepath$dd$FILE.$EXT)
die texexpand failed: $!\n;
to
$MYTEXINPUTS = $ENV{'TEXINPUTS'};
Why not set $TEXINPUTS = .:$ENV{'TEXINPUTS'}; ...
L2hos-syswait($TEXEXPAND $dbg -auto_exclude $unseg
. -save_styles $DESTDIR$dd$TMP_${dd}styles
. ($MYTEXINPUTS ? -texinputs $MYTEXINPUTS : '' )
... and not edit this latter line at all ?
. (($VERBOSITY 2) ? -verbose : '' )
. -out $DESTDIR$dd$TMP_$dd$FILE
. $texfilepath$dd$FILE.$EXT)
die texexpand failed: $!\n;
then things works very well.
I think the problem is
$TEXINPUTS
only includes the current directory.
Is my bug report correct or have I misunderstood something?
Yes, you have misunderstood that LaTeX2HTML is *not* based
upon a TeX engine, but implements the translation of LaTeX
coding in a quite different way. Much TeX coding cannot
be translated sensibly by LaTeX2HTML.
(more explanations below.)
If you want to verify the bug then TEXINPUTS to something.
Do
latex2html -debug ...
Verify that texpand does not get the right -texinputs.
What you are missing is that the environment variable
TEXINPUTS is usually used for TeX \input files and packages,
most of which cannot be interpreted by LaTeX2HTML, since they
are designed for layout of material on a static paper page.
Most packages and Plain-TeX \input files will just cause errors
in the high-level LaTeX-based processing performed by LaTeX2HTML.
Furthermore, since TEXINPUTS is frequently set to include the
*whole* texmf/ tree, including documentation files, it is
actually quite easy to get completely unrelated files \input
into a LaTeX2HTML job, causing all sorts of mayhem --- and the
user will be quite unaware of why material from such a file
has managed to get into his/her HTML pages.
(Consider how many files named test.tex, example.tex, ex1.tex,
letter.tex, etc. are located within your texmf/ tree.
These are then candidates to be included accidentally.)
In short, if you have a sensibly-defined TEXINPUTS environment
variable, necessary for a particular LaTeX job, then you should
be prepared to define a similar $TEXINPUTS Perl variable for that
job. (There are too many TeX installations out there with
badly-defined TEXINPUTS env variables to have $TEXINPUTS
inherited from it by default.)
Erling
PS. I would prefer a LOT that
latex2html -texinputs whateverpath .
was possible.
It's fine for experienced users of LaTeX2HTML to set this up
for themselves, but it is *not* fine for this to be the
default behaviour imposed by simply installing the software.
Hope this helps,
Ross Moore

Andersen wrote: Hi I do latex2html -external_file somewhere/toolsinstall.aux but nevertheless I get the error message: Cannot open toolsinstall.aux No such file or directory Maybe you should have ../somewhere/toolsinstall.aux . Relative paths for LaTeX2HTML need to be relative to where the HTML pages are built. Usually this is a subdirectory of where the source .tex file is located, hence the '..'. However, there is the option of setting a $DESTDIR, so it cannot be assumed that '..' is always applicable. (You need to work out the correct relative path, according to the other options that you use.) As to your question about a -texinputs option switch, you can use -init_file file and have the $TEXINPUTS setting stored there. (In this case, the file needs to be the path to the file relative to where the LaTeX2HTML job is initiated, as it is read before any real processing has begun.) This is certainly a good option to use with a Makefile, especially when the same Makefile is used to build several projects that may require different options. Hope this helps, Ross Well, -external_file is poorly documented in latex2html -help bit the help seems to indicate that is the way to specify an aux file.

Only the .pl files are not needed for the finished job itself.
However, these .pl files are retained since they are very useful
for further development of the site.
e.g.
images.pl retains information about what images have been
created, so do not need to be made again if you make any changes
and rerun the job;
labels.pl is useful if you want to make links into this site,
from another web-page being made with latex2html .
It tells you the values of all NAME=... attributes of the
anchor-points within the document; that is, places that can
be linked-to.
images.log is retained, since this can be useful when there
have been errors in the images, or if you want to check what
packages etc. were needed;
contents.pl, sections.pl, index.pl, internals.pl etc.
are generated when the pages are part of a Segmented Document.
This is similar to LaTeX's \includeonly{} mechanism,
whereby a set of pages may use indexing/auxiliary information
from other runs using a different part of a multi-file
document.
Can (or does or should)
latex2html
tell which files are important? [I ship my HTML document somewhere

Right now my solution to that problem is starting at
index.html
and then see what it links in recursive way. [I have implemented
it yet but by reading the HREFs it should be possible to figure
what is important.]
Only .html .css and image files are needed for a completed site.
The other files (e.g. the .pl ones) are for other purposes, as
described above, while the site is still under construction,
or for combining the site with other sites (labels.pl).

Is there a way to force it to use that package with all the related fonts, counting also the fact that Arabic words are written from right to left? LaTeX2HTML is *not* based on a TeX engine, so using there's no way to make those packages work. The logic needs to be recoded using Perl. Have you tried using the Omega variant of TeX ? That should give you HTML with Unicode.

Re: [l2h] Custom environments
Hello Prakash,
On 15/06/2004, at 6:20 AM, Prakash Countcham wrote:
Hello,
I have already sent this mail one week ago, but I retry as I didn't
find it in the archive. Sorry for duplicates.
The latex2html mailing list gets a lot of spam emails, and I don't
have
a lot of spare time to sift them for the legitimate mails from people
who haven't subscribed.
So it's better to subscribe first, then send messages.
I try to use latex2html to convert a document with custom
environments.
For example, here is a customized \input:
\RequirePackage{stack}
\NewStack{reldir}{.}
\newcommand\relinput[2]{%
\Push{reldir}{\Stack{reldir}/#1}%
\input{\Stack{reldir}/#2}%
\Pop{reldir}}
No, customising \input in this way cannot not work with LaTeX2HTML.
This is because LaTeX2HTML builds a single large job from the
main document, and its \input and \include'd files *before*
starting to process macros and environments.
Since \relinput is seen as an ordinary macro, it will not be
expanded to reveal the \input that it contains,
until after the job files have been amalgamated.
At that time, it is *too late* to add new material to be
interpreted within the job.
However, if you just want to make an image of the file's
(La)TeX contents...
First, I tried to let tex handle this command with:
process_commands_in_tex (_RAW_ARG_CMDS_);
relinput # {} # {}
_RAW_ARG_CMDS_
... then this approach can be made to work, ...
But the file in question is said not to be found even if it exists (I
don't know exactly why -- I guess it's because the generated files are
in a different directory).
... but note that TeX processing takes place in a different
directory to where your document sources are located.
Usually this is just one level deeper, so an extra '../'
in the directory path should be sufficient.
Then, I tried to adapt the subroutine do_cmd_input in the following
way,
but I have got the same problem.
$relinput_rep = .;
First try testing using
$relinput_rep = ..;
sub do_cmd_relinput {
local($_) = @_;
local($rep,$file,$output,$oldrep);
(s/\s*(.*)\s*\n/$rep =$1;''/s) unless (
(s/$next_pair_pr_rx/$rep=$2;''/eo)
||(s/$next_pair_rx/$rep=$2;''/eo));
(s/\s*(.*)\s*\n/$file =$1;''/s) unless (
(s/$next_pair_pr_rx/$file=$2;''/eo)
||(s/$next_pair_rx/$file=$2;''/eo));
local($after) = $_;
$oldrep = $relinput_rep;
$relinput_rep = $relinput_rep$dd$rep;
$file = revert_to_raw_tex(\\input{$relinput_rep$dd$file}\n) if
$file;
if ($PREAMBLE) { add_to_preamble('include',$file)}
elsif (!($file=~/^\s*$/)) {
$output = process_undefined_environment('center'
, ++$global{'max_id'},\\vbox{$file});
}
$relinput_rep = $oldrep;
$output.$after;
}
Any idea?
If no other errors were reported, then I think you just
need to sort out the path to the files to be read within
this context.
Hard-coding $relinput_rep = ..;
is not the most robust solution, since it'll be incompatible
with general settings for $DESTDIR .
More robust would be something like:
$relinput_rep = $RELINPUT_DIR||'..';
where, if necessary, you can set $RELINPUT_DIR
as a Perl variable in an initialization file.
I've also got other questions: Can I add a custom directory with my own
perl subroutines? Where can I find a documentation on how to add
personal
subroutines to latex2html (I tried to read the code, but a clear
documentation would be better)?
Initialization files are implemented for precisely this purpose.
See the -init_file filename switch.
You can use as many of these as you like; they'll be read,
and their Perl coding interpreted, in the order in which
they occur on the command-line.
There is a lot of documentation on this in the LaTeX2HTML
chapter of the book: The LaTeX Web Companion (Addison-Wesley).
Thanks for your help,
Prakash
Hopefully you'll be able to get your jobs working correctly now.
It's great to see someone willing to tackle the Perl coding
to get the job done.

Ross

Re: [l2h] LyX an LaTeX2html cannot handle tables

Hello Ross,

Many people process tables quite happily using LaTeX2HTML.
Yes, and I belonged to those people with the former versions in the

distributions of SuSE ;-).
It would help a great deal if you provided an example of the kind of
table
Yes, here it comes: the two examples are containing only a table of
two rows
with three columns. The first row contains the numbers 1, 2, 3 and the
second
the words one, two, three. But the first, correct one lies within a
section,
and the second, incorrect one within a subsection.
- schnipp first example only with section ---
%%LyX specific LaTeX commands.

\usepackage{babel}
\makeatother
\begin{document}
\section{This is a section}
\begin{tabular}{|c|c|c|}
\hline
1
2
3\tabularnewline
The problems stem from this use of \tabularnewline
instead of just using \\ as most authors would do.
LaTeX2HTML was initially written to cope with the kind
of markup that most authors can be expected to want to use.
Other constructions may need to be specially catered-for.
In fact, LaTeX2HTML does support use of \tabularnewline
when the {longtable} package is loaded:
\usepackage{longtable}
for tables that would extend over more than 1 printed page.
But it is only recognised within the environment:
\begin{longtable}
...
\end{longtable}
It seems that now \tabularnewline is recognised by LaTeX
in {tabular} environments, as well as {longtable}.
I don't know when that was introduced.
It would be appropriate for LaTeX2HTML to be updated
to support this too.
\hline
\hline
one
two
three\tabularnewline
\hline
\end{tabular}
\end{document}
--- end schnipp -
This leads to a correct translation of the site and the table appears
as the
listing shows:
H1A NAME=SECTION0001
This is a section/A
/H1
P

TRTD ALIGN=CENTER1/TD
TD ALIGN=CENTER2/TD
TD ALIGN=CENTER3/TD
/TR
TRTD ALIGN=CENTERone/TD
TD ALIGN=CENTERtwo/TD
TD ALIGN=CENTERthree/TD
/TR
/TABLE
The \providecommand{\tabularnewline}{\\} has resulted
in an early substitution of the \\s,
so this coding works as intended.
But the next example with subsections gets a bad result. The TeX-File
is:
schnipp example with section and
subsection-
%% LyX specific LaTeX commands.
%% Because html converters don't know tabularnewline
\providecommand{\tabularnewline}{\\}

two
three\tabularnewline
\hline
\end{tabular}
\end{document}
--- end schnipp ---
I cannot see any differences in the TeX-Files according to the
tabular-environment, but the HTML result this time is:
H2A NAME=SECTION00011000

/H2
P
TABLE CELLPADDING=3 BORDER=1
TRTD ALIGN=CENTER1/TD
TD ALIGN=CENTER2/TD
TD ALIGN=CENTER3
BR
one/TD
/TR
/TABLE
But here, the \tabularnewline has not been substituted-for early.
Instead it has been later treated as \newline within a table-cell.
Very peculiar is, that the first entry of the second row now appears
in the
last cell of the first line. But nothing else follows. All other rows
an
contents do not appear.
LaTeX2HTML has seen this as a table with just a single row of cells,
and discarded all the excess cells.
Hm, do you have an idea?
I'm not at all sure about why the 2 situations produced different
results.
I have some ideas about how this may have occurred; but in any case,
it's
not right that this is happening.
Anyway, until I patch this bug in LaTeX2HTML, there is an easy fix
that you can use:
replace the line
\providecommand{\tabularnewline}{\\}
with the TeX definition:
\def\tabularnewline{\\}
This certainly works with your example, both with and w/out subsections.
It should be OK for normal LaTeX too, except perhaps with some exotic
packages that redefine \tabularnewline for themselves.
Hope this helps,
Ross

Hello Hans,

Sorry, I've been away for the past few days, so have only now
had a look at the problem.
There are several ways to tackle it, each depending upon
just what you want to produce for the HTML of the listing
environment.
If you want just a simple verbatim listing of the code,
set within PRE ... /PRE tags, then one approach is
to hook into LaTeX2HTML's treatment of 'verbatim-like'
environments.
*Any* environment which has either 'verbatim' or 'Verbatim'
in the name will be processed that way automatically.
So you could do:
1. place the following coding in the preamble:
%begin{latexonly}
\lstnewenvironment{myverbatim}{}{}
%end{latexonly}
2. change all of your usages of:
\begin{lstlisting} to \begin{myverbatim}
\end{lstlisting} to \end{myverbatim}
Now the document should process fine in both
LaTeX and LaTeX2HTML.
*Any* environment name containing 'verbatim' could be
used here' it doesn't have to be 'myverbatim'.
One problem with this solution is that an optional
argument to the listing environment is not recognised
as such by LaTeX2HTML. There's no simple way to overcome
this without some edits to the coding of the 'texexpand'
and 'latex2html' Perl scripts.
However, maybe you want the HTML to be an image of the
environment that LaTeX would produce, as at present
where the {lstlisting} environment is treated as being
*unknown*.
In that case, best would be to write a short Perl
subroutine, named do_env_lstlisting as follows.
sub do_env_lstlisting {
local ($_) = @_;
my $env_id = ++$global{'max_id'};
$_ =~ s/\\par/\n\n/g;
process_undefined_environment('lstlisting', $env_id, $_);
}
This could be placed in an initialization file,
or in a file listings.perl for loading in response
to the \usepackage{listings} command.
Such a package module could then be expanded to provide
greater support for the options and syntax defined
in the listings.sty LaTeX package.
Hmm. That \n\n replacement may not work under DOS/Windows,
where the line-ending character is different.
If that's a problem, try instead:
sub do_env_lstlisting {
local ($_) = @_;
my $env_id = ++$global{'max_id'};
$_ =~ s/\\par/
/g;
process_undefined_environment('lstlisting', $env_id, $_);
}
... or buy a Unix box. :-)
The trick to produce an empty line which should not appear as '\par'
in latex2html's graphical output is to print something invisible in
that line, for example a white word on white background. You can
achieve this as follows:
Ouch; that's a pretty nasty kind of hack --- clever, mind you!
--- and it only works for an image as output.
\documentclass{article}
\usepackage{listings}
\usepackage{color}
\lstset{backgroundcolor=\color{white},frame=single,emph={EMPTY},emphsty
le=\color{white},}
\begin{document}
\begin{lstlisting}
print ``Hello World!''
EMPTY
print ``Done''
\end{lstlisting}
\end{document}
Note that the DVI output of this looks ugly (black boxes) but the PS
is okay (that is because the color-package does color using post
script commands so it is not expected to work for the dvi files).
Note also that the backgroundcolor for the listings environment has to
be set: listings seems to be quite clever and changes the background
to gray if you try to print something in white.
If anyone comes along a decent fix for this problem, please let me
know.
The big question is what do you want to see in the HTML?
an image, or preformatted text (i.e. PRE /PRE tags?
Hope this helps,
Ross

Is the images.dvi file constructed correctly --- have you looked at images.log ? Have you tried using the -debug switch ?

(I've frittered away endless hours so far on this. At one point I gave up and just used tex4ht instead, which can produce, as an option, html files that use MathML rather than graphics images. But tex4ht doesn't do the nice division of documents into separate pages that LaTeX2HTML is supposed to do.) Are browsers doing a good job of displaying MathML created this way ? If so, then that's an ability that I'd like to add to LaTeX2HTML also. Indeed it's been on the TODO list for some time. Finding time to do the required programming has been the main barrier to this.

Re: [l2h] Problem with Gif generation after MiKTeX 2.4
Hi Peter, On 27/10/2004, at 9:27 PM, Peter Morling wrote: Hi, after installing MiKTeX 2.4 the gif-generation causes errors, please se the attached image, a blick line at the bottom of the gif box. However, if you set the MATH_SCALE_FACTOR = 1.8; the problem will disappear again. But it'll force you to use a rather large presentation of your math statements. I have tried the excact same for MiKTeX 2.3 and this causes no problems. So i come to this conclusion, that MiKTeX distributes some new dimentinons of fonts or maths used by L2H when calling programs in NetPbm. Hmm; could be. More likely is that, with the update, you are now using bitmapped fonts, whereas previously you were using PostScript outlines (i.e. .pfb files) or perhaps vice-versa. I suggest that you run some tests of LateX2HTML, using the -debug switch. Observe in the log-window where the fonts are coming from. Also, look at images.dvi (and perhaps also at images.log ) to see if anything looks wrong. In images.dvi each image should be bracketed left below by an L-shape, which is used to control the size of the image by its inside height and width. If that L isn't formed cleanly then you'll get incomplete cropping to the correct size. How do i fix this problem? We need a fuller diagnosis first. Hopefully the above will help you do this.
