\Section{Package patching handling}
%%%%%%%%%%%%%%%%%%%%%%%%%

%%%%%%%%%%%%%%%%%%%%%%%%
% tutorial begin
%%%%%%%%%%%%%%%%%%%%%%%%

By default, .4ht files are loaded at begin document. When we need to patch 
a package at the moment when it is loaded, we can use the mechanism provided
by usepackage.4ht.

The obsolete way is to use the following construct:

\Verbatim
\<use package\><<<
packagename,>>>

\<add to usepackage\><<<
\def\:temp{packagename}\ifx\@currname\:temp
% package redefinitions
\fi
>>>
\EndVerbatim

The downside of this that it loads usepackage.4ht again for each package
it detects. This can slow down the compilation.

The recommended way is the following: 

\Verbatim
\<add to usepackage\><<<
% use package name as the second argument and name of the file
% that contains redefinitions as the third 
\Configure{PackageHooks}{packagename.sty}{packagename-hooks.4ht}
>>>

\<packagename-hooks.4ht\><<<
% packagename-hooks.4ht (|version), generated from |jobname.tex
% Copyright 2020 TeX Users Group
|<TeX4ht copywrite|>
% package redefinitions
>>>\AddFile{9}{packagename-hooks}
\EndVerbatim

The contents of the hooks file can be following:

\Verbatim
% code before package is loaded
% ...
\:AtEndOfPackage{
  % redefine package commands that are used in the preamble
  % ...
}
\EndVerbatim

You can use the following special commands in the hooks file:

\Verbatim
\:dontusepackage{packagename} % prevent the package from loading
\:AtEndOfPackage{code} % redefine macros that can be used in the document preamble
\EndVerbatim

 Latex prohibits content before the \`'\begin{document}' by putting
\`'\ht:everypar{\@nodocument}' before
\`'\begin{document}' to  get an error if text appears before the
beginning.  A possible solution is to put sensitive stuff
in, for instance,  \`'{ \let\@nodocument=\empty ...}'.

It is unsafe to define \''\romannumeral' because it is used
within immediate definition \''\edef', as well as definitions of macro
names \''\csname ...\romannumeral ...\endcsname'. Consider also
\''\Configure{enumerate}' (e.g.,

The \''\%' command needs to be redefined for TeX4ht source files,
but this redefinition causes compilation errors when it is used in
titles or captions. So we redefine it to the original LaTeX
definition. We can detect if we are in the literate sources by checking 
if the \''\MAKETITLE' command is defined.

See \Link[https://tex.stackexchange.com/q/652848/2891]{}{}

\`'\Configure{ref}{\Link}{\EndLink}{anchor}' tells what \''\Link'-type command
should be on insertions of \''\ref'.  If the third parameter is empty,
the anchor is the one provided by the system. If the first parameter
is empty, no Link is assumed.

\item
\''\Configure{newlabel}{\cur:th \:currentlabel}{#1}' supplies the
target address and the anchor.  
\item
\''\Configure{newlabel}{}{#1}' 
is equivalent to
\''\Configure{newlabel}{\cur:th \:currentlabel}{#1}' 
\item
The
\''\Configure{newlabel-ref}{\rEfLiNK}' command provides an
intermediate link command for the aux command, which
\`'\Configure{ref}{\Link}{\EndLink}{anchor}' configures.   If the first
field of the  last configuration command is empty, than the anchor is
provided without its surrounding.

Yes.  I believe the reason was to avoid ambiguities--unfortunately,

The second parameter of \''\anc:lbl' is a counter name, when such is know.

The \`'\@currentlabel' comes sometimes with font info.  Normally, it
comes from \''\refstepcounter' in the form of

name which is provided in the parameter of \''\cur:lbl'.

The following is late arrival into TeX4ht, inserted for handling
\''\newtheorem', and possibly other structures.  It might cause
duplicated anchors.  At least in the  case of figures and lists they
are overided by other anchors, and hence not needed. In case of 
lists and new theorems we ended to delete the overriden case. Still
need to do it
for pictures, and amybe also other cases.

The \''\refstepcounter' may appear in places (e.g., before first item
of a list) where no text is allowed, hence we have to ensure that
\''\anc:lbl' will not break this restriction.
How about within pictures?

To reduce conflicts, we deal with labels indirectly
through a counter. The counter is increased before
\''\getlabel' and after \''ref'. That is, this pair is assured
consistency of a label.  The separation between \''\GetLabel' and
\''\PutLabel' is
to allow the latter one into immediate arguments such as \''\HCode'
and \''\Tg'.

\''\label' sends its info to \''\getlabel'. It insert a

Biblatex recently started to complain about ifthenelse
patching. It is quite strange, as this patching code is quite 
old and there were no such errors previously. Anyway, 
this code should try to patch ifthenelse using TeX4ht built-in
mechanism for ifthenelse.

We defined the hook macro depending on presence of Hyperref. 
I don't remember why, but it seems to works with Hyperref now,
so the package condition seems unnecessary. It even produces
an error when Hyperref is used before BibLaTeX, so I think
we should remove it.

This sections is kept here just for the future reference, the 
next section is actually used:
\<\><<<
\@ifpackageloaded{hyperref}{}{%
\ifdefined\TE@hook\else%
\def\TE@hook{}%
\fi%
}
>>>

Define TE@hook so BibLaTeX don't try to patch ifthenelse.
We put the hook ourselves thanks to Configure{ifthenelse}.

2022/07/25:  It seems that we don't need to redefine MakeUppercase and MakeLowercase, BiBLaTeX works without these
redefinitions, and on the contrary, we get compilation error with these, as they were changed in the LaTeX kernel. 
So I think it is best to remove them.

% <Kristian.Debrabant@cs.kuleuven.be> reported that After updating
% biblatex and biblatex.ht to versions 2.2 respectively
% 2012-09-28-17:49 (using MiKTeX 2.9 64 bit), tex4ht seemed no longer
% respected the defernumbers option in biblatex.sty: When applied to

%

% Version 2 configurations for nameref.4ht was added consequent to

% Bitouz\'e <dbitouze@wanadoo.fr>. A thorough revamping was needed to
% fix the problems. Apparently, in my tests, all reported problems
% seem to have been fixed, though, \label{...} when used inside the
% caption appears when \nameref'ed. Also, \@begintheorem with amsthm
% loaded needs to be tried and tested thoroughly. Otherwise, the fixes
% are OK as vouched by Martin and Denis.
%
% A new function \defineautorefname has been defined and included in

% names will resolve to the correct printed enunciation name when
% \nameref'd. Users need not separately define the same.

Bug 348: Support for amsmath environments

We can easily define \`|\NR:Type| and \`|\NR:Title| in 
\`|\Configure{@begin}{env name}{definitions}|. I didn't knew about this
configuration until now. It seems to be useful when we need to inject something
into the environment without messing the existing \`|\ConfigureEnv|
definitions.

This is a really nice variant of Computer Modern in OpenType format. The

Updata 2021/12/08: There is still error. I had to reintroduce Nameref to
hyperref-hooks.4ht, because it's removal broke lot of documents that don't 
use BibLaTeX. BibLaTeX + Hyperref remain broken.

Update 2021/11/04: the following information is here for the historical reasons.
We don't load Nameref from BibLaTeX anymore. I've found that we need to 
remove Nameref from hyperref-hooks.4ht and then everything works.

Historical info: 
BibLaTeX and TeX4ht both redefine the \Verb|\ifthenelse| command. We take care 
of it in biblatex.4ht by defining the \Verb|\TE@hook| command. But some BibLaTeX
styles still have issues (namely "anbt"). I've found that loading of "nameref"
package helps in this case. 
\Link[https://tex.stackexchange.com/a/619816/2891]{}{}More info\EndLink.

We also need to post-pone the Nameref loading outside of the hooks file, as
it seems to cause other issues if we used \Verb|\RequirePackage| directly.
We can utilize the LaTeX hook system for that.
\Link[https://tex.stackexchange.com/a/620503/2891]{}{}See this issue\EndLink.

Fix for French Polyglossia. It makes lot of characters active. This can clash 
with TeX4ht. For example : character in title results in fatal error.

We have to alter package fontspec loading, as it causes tex4ht to fail.  Some
macros are redefind to do nothing, as we don't really need OpenType fonts
handling in tex4ht

The defintions for fontspec are rather big, we moved them to standalone file
to save some time in package checking.

We also  want to load fontspec only once, it fails with Polyglossia otherwise.

are loaded latter, for example with calc.sty. The catcodes are stored in

We must declare support for used unicode characters when XeTeX is used. Support
for Latin script is loaded automatically, for other scripts Script option for
font family declaration must be used:

\Verbatim

\usepackage{polyglossia}
\setmainlanguage{czech}
\setotherlanguages{greek}
\newfontfamily\greekfont{Linux Libertine O}[Script=Greek]

Latin text
\begin{greek} 
  greek unicode text. this file is in latin1 encoding, so we 
  can't show it 
\end{greek}
\end{document}
\EndVerbatim

Alternatively, you can eiter directly declare unicode range using
\`|\xeuniregisterblock{start charcode}{end charcode}|, or load ranges for
given Script using \`|\xeuniuseblock{Script name}|.

There is a support for TikZ externalization. TikZ has been instucted to don't
externalize pictures when tex4ht is used. It is necessary to  create the PDF
images for TikZ pictures first, by compiling the document using a PDF producing
engine. 

The tex4ht configuration for PDF graphics is used for PDF inclusion, it will be

The following modification became necessary consequent to the bug
report filed by Alex Ball <a.ball@ukoln.ac.uk>. The bug was that
hyperref.4ht failed consequent to the combination of memoir + hyperref
deal with section headings that are below the numbering threshold as
set by secnumdepth. Alex vouched that the fix worked fine with his
documents.

This code comes from hyperref-hooks.4ht. As hyperref-hooks.4ht is not used in .cls files
it needs to be executed also here. I've left this code in hyperef-hooks, but it probably can 
be removed safely.

We need to load Nameref here, otherwise lot of documents
that use Hyperref fails. This caused issues with BibLaTeX,
as both Nameref, BibLaTeX and TeX4ht redefine ifthenelse command.

So we load explicitly the Ifthen package, let Nameref redefine it,
and then revert to it's original definition before applying of
TeX4ht hooks.

Hyperref defines following captions at the end of the package. 
The problem is that Hyperref detects TeX4ht, and stops its
loading too early, before the captions are declared. 
They are available in the document, but not in the preamble.
This can result in compilation errors if user tries to redefine 
one of these captions in the preamble.

The \''\nosp:arg' removes leading spaces from attribute names.
Why \`'\def\del:sp#1//{\def\nosp:arg{#1}}' doesn't work?

January 2017 (Michal): LaTeX core started to use new font encoding with
Unicode engines, TU. This encoding loads OpenType fonts by default.
It breaks tex4ht compilation due to a bug in tex4ht command.

We need to check for TU encoding and switch back to the old default one, OT1. 

LuaLaTeX and XeLaTeX also started to support basic Latin Unicode diacritics, 
so the following example should output all characters to the PDF:

\Verbatim
\documentclass{article}
\begin{document}
We can't use diacritics in the \Verbatim unfortunately, 
so just imagine that it is here.
\end{document}
\EndVerbatim

We should support that as well. For LuaLaTeX, we can use a callback which is used 
for Fontspec support. For XeLaTeX, we need to make Unicode characters active and
define them to output te4ht character code. Again, we can use the code which was
used for Fontspec support.

The \`'\ifx \EndPicture\:UnDef...\fi' should be inside
\''\recall:afterend', and not on top of it, because we want the conditions 
that exited before entering the group. It is expressed indirectly theough
\`'\chk:pic'.

A definition \''\HLet\end\...' would not work for cases that pictures
are initiated within  \''\begin{...}'. For instance, in eqnarray there
  is an embedded \`'$$' that can start a picture environment.

The \''\csname before:begin#1\endcsname' sends \''\csname

The  \''\thebibliography' contains a \`'chapter*'  which is
a problem here in case of cutoff because we get
\`'\SaveEverypar....\HPage...\RecallEverypar....\EndHPage', 
where the hypertext also saves and recalls the status. Hence, a partial 
overlap that would have forced a warning.

The \''\RecallEverypar' must appear first because it sets the
counter \''\n:list', the appropriate \''\ht:everypar' contents,
and \''\ShowIndent' or \''\IgnoreIndent'.

The \''\@doendpe' deals with piles of \''\end's.     The 
\`'\Protect\HtmlPar' goes to the first paragraph outside the
pile.

>>>

The \''\hfill\break' is to help prevent losses of space separators. But it seems to
insert spurious space when an environment is used inside paragraph, so I've removed
it. I hope that it will not break anything.

We might get here leading empty paragrphs after an \`'\end'. Is there
a way to remove them without a post processor.

We can't add grouping of the  form
\`'\append:defI\begin{\bgroup}.......\pend:defI\end{\egroup}'
 for catching enclosed fonts because \''\begin{...}' commands might
include parametric subcommands like in
\`'\begin{list}{default-label}{definitions}...\end{list}'.

La\TeX{} changes the meaning of \`'\ht:everypar' upon reaching
\`'\end'.  Hence, the \`'\ht:everypar{}\begin{...}...\end{...}' does
not let the effect of \`'\ht:everypar' through.

LaTeX release from October 2020 made spacing commands originally available only in the math
mode available also in the text mode. The following configurations are based on the LaTeX kernel
of this release. The configurable hooks are used only in the math mode, as they were used in 
this way originally. These configurations are used in the MathML mode.

A \big? is internally defined as a construct `\left?\right.', where
normally costructs of the form `\left?...\right?' are used for larger
formulas (that TeX4ht converts to formulas}.  I changed, at least for
the time being, the definition of \big to avoid creating pictures for
its arguments.

>   + to not be recognised as equal (i.e., two ['s in two places will be
>     written as two GIF files).

This is a problem that I don't have a satisfying solution for it
(except of providing some tools that allow with minimal user
intervention to eliminate duplications).  At some point I toyed with
the idea of using a perl script to reduce duplications, but I shelved
it as a low priority task.

> This is unpleasant, and I wonder if TeX4ht can do something about it (I

The code is fine in this case.  TeX4ht should take the full blame.

>>>

We insert the \''\leavevmode' to ensure that all \''\items'
at the beginnig of lists are true. Otherwise,  the lack of them causes 
a lose of html-info  during collapsing effects as is the case, e.g., in
the following code.

\Verbatim
    The ten characters
    \begin{quote}\begin{verbatim}
    #  $  %  &  ~  _  ^  \ {  }
    \end{verbatim}\end{quote}
    should no
\EndVerbatim

In addition, without the \''\leavevmode' we can end up with an
outcome \`'<CODE 
>
      <LI>
      \@</CODE>' instead of \`'<LI><CODE 
>
      \@</CODE>'.

Within \`'|<prepend @item[...]|>', \''\if@noitemarg' indicates
whether we have a non user supplied label.  Within
\`'|<append @item[...]|>', \''\if@inlabel' does the job before
we encounter the first paragraph.

Note that \''X1111
   Y2222
   X1111
   X2222'
is the output of \`'\ht:everypar{X\ht:everypar{Y}}
    \par
1111
    \par
2222
    \par
\ht:everypar{X\ht:everypar{Y}}
    \par
{1111}
    \par
{2222}
'.  That is, the everypars might happen within groups. Hence, 
probably the reason for \''\if@inlabel'

\<append @item[...]\><<<

   \if@newlist |<start new list|>\fi

   \ht:everypar{|<between list pars|>}}%
>>>

\<before each item\><<<
\global\let\empty:D:T:D|=\empty \:DT \hfill\break   
>>>

The \''\hfill\break' prevents collapsing of spaces.  We want to put
\'' \:DT ' at the end so it will gobble only the item mark.  However,
we can't because of the problem of collapsing spaces.

Because of the merging of into items lists that are

The \''\ConfigureEnv' is needed for getting paragraph breaks 
after collapsed lists.

Do we need to to globally define \''\:DLL' here to empty,

\item[The default.] The default partition to boot can be the first
one, the one with the active flag set, or can be configurable, depending
on the MBR. Some MBRs set the active flag in the MBR to the selected
partition, and hence default to it the next boot. This requires
rewriting the MBR, and therefore may conflict with virus protection
present in some BIOSes.

Note that there is another reason for setting the active flag to the
booted partition, and rewriting the MBR: MS-DOS gets horribly confused

In early version we got a coplain that \''\unpenality' is not allowed
in vertical mode from the following code.

\Verbatim
\begin{trivlist}  \item\relax
    \ht:everypar \expandafter{\the\ht:everypar \unpenalty}
......
\end{trivlist}
\EndVerbatim

When an item is encountered it calls \''\makelabe' to create the label.

Commands \''\setbox...= box{...}' might produce extra spaces because
of the \''\par\leavevmode', an undesirable phenomena for framed
pictures.  Since boxes are in any case a problem for us for standard
text, we are probably better-off deal properly at least with pictures.

The \''\verse' carries the following def.

The verse environment doesn't seem to need the 100\% width but we
include it because it costs nothing and without it there is a slight
deviation in the left margin from the quotation environments The
groups are for enclosed groups.

In LaTeX, these environment mainly enlarge the margins.

\Verbatim
         \newenvironment{quotation}
               {\list{}{\listparindent 1.5em%
                        \itemindent    \listparindent
                        \rightmargin   \leftmargin
                        \parsep        \z@ \@plus\p@}%

The zero margins are in particular important for avoiding 
extra spaces in nested verbatim environments.

\Section{Abstract}

Standard LaTeX classes use centering environment to place abstract title. 
We want to place some configurable tags instead of that centering. For example
header element. To do that, we can use the new LaTeX environment hook mechanism
to redefine configuration of centering at the beginning of abstract.

Boxes are occasionally before placing them within pictures. In such cases,
configurations of the form 
`\Verb!\Configure{lrbox}{\noexpand\PictureOff}!'
might be useful.  We don't want such configurations for a default,
because of possible nested pictures such as in 
  `\Verb!\newsavebox{\bx}

The \`'\picture' does not offer text substitute (too much pain to
create them).  Also note that \`'\Picture+{}' puts the picture in a box, but not so \`'\Picture+[]{}'

DON't we need in the following \''\LaTexEnv'

\<latex ltpictur\><<<
\let\lt:pic|=\picture
\def\picture{%
   \ifx \EndPicture\:UnDef
      \a:picture
      \let\end:lt:pic|=\endpicture
      \def\endpicture{\end:lt:pic \b:picture}%
   \else \let\EndPicture|=\empty
   \fi\lt:pic}
>>>

Picture environments, and other also, can be indirectly nested in
setbox comamnds. Hence the setting of \''\EndPicture' to empty
for nested occurances of \''\endpicture'.

\<latex ltpictur\><<<

% \ConfigureEnv{picture}{\leavevmode}{\HCode{<BR CLEAR="ALL">}\Indent}{}{}

The BR tag is used to force line breaks within text.
Normally, linebreaks are treated as a space by browsers
(except inside the PRE tag). The optional CLEAR
attribute is used when you have an IMG image in your
text. If that image uses ALIGN=LEFT or
ALIGN=RIGHT, the text will flow around it. If you have
text you want below the image, you can do this with
{\tt <BR CLEAR=LEFT>} or CLEAR=RIGHT to force
scrolling down to a clear left or right margin,
respectively. Using CLEAR=ALL will scroll down until
both marings are clear. CLEAR=NONE is the default,
and does nothing.

In latex.cls \''\@thm'  is defined with two arguments, and in
amsthm.sty with three parameters. In both cases we have a
\''\@currentlabel' defined through a \''refstepcounter', and
the latter command introducing its own identity, instead of that
of the theorem, into the xref file (and then the href fields
of the html tags). The following code corrects that behavior.

\<latex ltthm\><<<
\def\:thm{\o:@thm:}
\def\:temp{|<seed begin theorem|>\:thm}
\HLet\@thm|=\:temp
\let\o:@endtheorem:|=\@endtheorem

A page break before an item might have a different behavor than a
regular start of a paragraph at an item. Hence, the following code.

\<no page break before item\><<<

\Section{Shared Below Chapter Stuff}

Sectioning commands can be called directly through their default
definitions, or indirectly throught \''\rdef:sec'.  

The latter invocation calls a corresponding tex4ht command:
\''\:likefoo' in case of a starred commands, and \''\no:foo' in case
of non-starred commands. Then it invokes the original definition,
without a title, to extract the native changes in the environment,
such as counter numbers.

Redifine \''\index' and \''\glossary' to add the \`'\beforeentry{file
name}{tag}' before each \''\indexentry' and each \''\glossaryentry',
with default definition for \''\beforeentry' to eat its fields and do
nothing. 

In addition, The command inserts a tag at the file. To get a
pointer to the file, all we need to insert te redefinition
\`'\def\beforeentry#1#2#3#4{#3{\Link[#1]{#2}{}#4\EndLink}}' which puts
the link on the page number (for whatever the page number is good, or
replaces it with another mark).

The four parts indicate what should appear at the head, before
each label, after each label, and at the tail of the lists.

In the default setting, the lists that are not referenced through
block-environments are supposed to create no code. We made this choice
because there are many trivial lists that just create
indentation in LaTeX that is undesired in html. The outcome of such
lists would probably have been \`'<DL><DT><STRONG></STRONG><DD>.....</DL>'.

This can cause too much burdun on TeX as far as resources are
concerned.  Instead TeX4ht sets the lines and spaces to flexible
dimensions, and  hides the warning messages from the users.

You can turn the overfull warning messages on with the `fussy' option
of \Preamble.  So far I never found this option to be useful,
and I suspect that the only place it can become useful is when
dvi pictures overflow the page dimensions.

fussy option in \Preamble to see box overlows.  Typically, this

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

For center, flushleft, and flushright we don't want identation, so we
can't use tables for separating from above and below. Similarly is the
case for tabbing and verbatim, but they get separate treatment.

In TeX4ht, \''\begin{...}' and \''\end{...}' are redefined
to \''\SaveEverypar\begin{...}' and \''\end{...}\RecallEverypar' 
so it is pointless to directly deal with paragraph breaks 
and saving.  Since the saving and recalling are global
operations (in a pushdown fashion), the above
redefine the saved environment to eliminate 
paragraph breaks after the environment.

WE HAVE here a problem if someone goes directly, e.g., for
\''\quotation...\endquotation' instead of 
\''\begin{quotation}...\end{quotation}'. On the other hand, 
LaTeX doesn't mention the first case as an option.

\Chapter{Display-Paragraph Environments of LaTeX}

Environments to consider: quote, quotation, verse, center, flushleft,
flushright, tabarray (tabular/array), tabbing, and verbatim. The
last two may be combined into quote or quotations. With the exeption of
the last two, they are all displayed-paragraph environments (C.5 in LaTeX).

The above environments are built on top of \''\list...\endlist' and
\''\trivlist...\endtrivlist' in LaTeX, and there we impose the html
code.  That is, we use \''\Configure{lists}' that is common to both
constructs.

>   - More serious is that the verse and quote environments are still
> centered in Powerbrowser. 

The reason is probably that Powerbrowser does not recognize the
property WIDTH="1" in <TD>, a feature that should be legal in html 3.2.

> The html output for my address, for example,
> looks like this:
> 
>   <TABLE
>   WIDTH="100%" CELLPADDING="0" CELLSPACING="15"><TR><TD
>   WIDTH="1"></TD><TD
>   >
> 
>        XX XX<BR>
>        XX<BR>
>        XX xx<BR>
>        The xx<BR>
>        email: <A HREF="mailto:xx@xx.nl">xx@xx.xx</A>
>   </TD></TR></TABLE>
> 
> If I remove the ``WIDTH="100%"'' from the table tag, this is fixed,
> without breaking anything in MSIE or Netscape.

Once you remove the WIDTH property, the width of the table is
determined by its content instead of the page dimension.  This
can cause adversary conditions for nested environments.

For instance

   \documentstyle{article}
   
   \input tex4ht.sty \Preamble{html}  \begin{document}   \EndPreamble
   
   \begin{quote}
   The buck stops here.
   \begin{flushleft}1\\123\\12345\end{flushleft}
   \begin{flushright}1\\123\\12345\end{flushright}
   \end{quote}
   
   \end{document}

creates the outcome

   +-------------------------------------------------------+
   | The buck stops here.                                  |
   |       1                                               |
   |       123                                             |
   |       12345                                           |
   |                                                       |
   |                                                     1 |
   |                                                   123 |
   |                                                 12345 |
   +-------------------------------------------------------+

which translates to the following one when the WIDTH property 
is removed.

The following was for

and files like 
\`'/n/candy/0/tex/teTeX/texmf/tex/latex/base/latin1.def'.

But 2022 release of LaTeX don't need special handling of \`'\@tabacckcludge',
the accents works even when we remove the following redefinitions.

What is more serious is that these redefinitions of MakeUppercase and
MakeLowercase don't change text case anymore, and it also causes
compilation error for the \`'\chapter' command. So we need to 
disable it even if it was useful in some older documents.

I redefined \@tabacckludge to handle the problem for TeX4ht.  I don't
yet fully understand the purpose of \@tabacckludge, but I guess that
changing latin1.def will cause font problems in standard mode.

The issue of font decoration in math is currently problematic.   

*  In unicode, decorated symbols get distinguished codes if 
   the decoration implies special math meaning.  Consequently,
   symbols with `meaningful' decorations should be embedded 
   in decorated unicode entries, whereas `meaningless' decorations
   should be set through style sheets (e.g., css or xslt). 

*  The behavior of latex doesn't seem to always be meaningful, for
   instance, \mathbf in the following example.

     \documentclass{amsart}
        \RequirePackage{bm}
     \begin{document}
     
       \def\x{ A + \alpha + \Delta }
     
       $ \x            $ \par       % none in bold
       $ \bm{ \x }     $ \par       % all in bold
       $ \mathbf{ \x } $            % just A and Delta in bold
     
     \end{document}
     
*   The decorations by \bm, I think, should be considered meaningless.
    Currently they can't be realized through style sheets, because the
    browsers don't seem to support such capabilities for mathml.

*   A few cases, like \mathbb, seem to have `meaningful' decorations.
    So tex4ht tries to implement these decorations.

I always hated this part, and I hope I'll have enough time to fix it
before the text will go out of my hand for publication.
(Historically, I introduced the \like... commands to save the users
employing code like \expandafter\foo\csname ...*\endcsname.  I suspect
that historical reason is not valid anymore.)

not to break paragraphs, we put line breaks.  So, for instance, 
centered paragraphs retain their shapes.

\`'\\[...]' and \''\\*[...]', in normal mode, are
 implied from \''\@xnewline', and in turn on \`'\newline' and \''\vspace'.
More recent definitions of latex rely on \''\@gnewline'.

The recent latex.ltx file introduced the code

\Verbatim
   \global\let\if@newlist\@@if@newlist
\EndVerbatim

at the end of the \''\@outputpage' macro.  In the case of plain latex, I
suspect, the task of this code is to avoid extra vertical space before
a list which starts at the top of a page.  This effect is achieved by
having the \''\if@newlist' changing to false from true at the page break.

In the case of tex4ht, the side effect of losing the list header
caused also the loss of the code \''<ul>'.

Latex 200 introduces \`'\global\let\if@newlist\@@if@newlist' at the
end of the \''\@outputpage' routine.
Without the following, we loose start of new lists at top of pages. 

\<latex 2000\><<<
\ifx \@@if@newlist\:UnDef \else
  \pend:def\@outputpage{\expandafter\global \expandafter\let
      \expandafter\@@if@newlist\csname if@newlist\endcsname}

We can't play with the following because we may get extra \''<BR>'s
for paragraph breaks \''<P>'.

Indexing support for Memoir. It supports split index like functionality,

they were stripped by the literate programming system.

\Section{Sectioning}
%%%%%%%%%%%%%%%%%%%%

The latex classes use \`'\@sec' and \`'\@ssect' for defining sections
and starred sections.  The ams classes use only the first feature for
both types of classes, but assume negative depth \''\@m' for the depth
of starred sections (tex4ht records the level value in
\''\c:secnumdepth').  Hence, the \`'like' versions of the sectioning
comamnds are (currently?) not provided for the ams classes. The
\''\Configure{@sec @ssect}' is needed only for the \''@sec'; a
configuration for \''@ssect' is ignored.

The split environment looks like 
  \`'\begin{split}...\begin{split}...\end{split}...\endmathdisplay@a'.
The folowing tries to compensate for the above extra openning split 
environment.   

But in 2023, this causes fatal error in the compilation. Furthermore,
the test cases that follows work in the picture and MathML modes, 
so it seems that it isn't necessary anymore.

Bug report for the fatal error can be

This should prevent compilation errors with commands declared using \''\DeclarePairedDelimiter' and MathML. 
We need to patch the command at the moment when it is declared, so it must be available
already in the preamble. This is why we use early hooks.

The \''\label'  gets a definition that differs a little than the one in LaTeX, and is more complicated because of cases like in the example:
\Verbatim
\documentclass[fleqn]{article}

\title{Test of subequations environment}
\author{mjd}

\usepackage[noamsfonts]{amstex}
\numberwithin{equation}{section}

\newcommand{\env}[1]{{\normalfont\texttt{#1}}}

   \begin{document}

`\section{Prime equation numbers}

Here is a,b,c sub-numbering.
\begin{subequations}{a}
\begin{eqnarray}
A&=&B\\
D&=&C \label{e:middle}\\
E&=&F
\end{eqnarray}
\end{subequations}
That was produced with the \env{eqnarray} environment; the middle line
was labeled as \eqref{e:middle}.

First an equation.
\begin{equation}\label{e:previous}
A=B
\end{equation}
That was equation \eqref{e:previous}.

\begin{equation}%
\tag{\ref{e:previous}$'$}
\label{e:prevprime}
C=D
\end{equation}

 And that was equation \eqref{e:prevprime}.

First an equation.
\begin{subequations}{a}
\begin{xalignat}{2}
\label{xalignat:a}A+B&=B&     B&=B+A\\
\label{xalignat:b}C&=D+E&     C\oplus D&=E\\
\label{xalignat:c}E&=F&       E'&=F'
\end{xalignat}
\end{subequations}

Label check: that was \eqref{xalignat:a}, \eqref{xalignat:b}, and
\eqref{xalignat:c}.

\end{document}
\EndVerbatim

We have llncs.cls for latex2e, and llncs.sty for latex2.9.

llncs.cls loads article.cls and then its definitions. Hence,
llncs.4ht asks article.4ht to load the definitions in llncs-a.4ht

\SubSection{Initialize the Hooks}

So far the hooks have been initialized to do nothing.

\SubSection{Fix}

The original file has the code \`'\setbox\curbox\box \ifdim\wd\@ne>\z@ \@ne \else\voidb@x\fi'.  That code is problematic because we can reach widths
larger than can be measured by the \`'\wd' command.

The space above the title is needed to separate it from the `typset by AMS-TeX'
that is automatically printed.

> A minor problem showed up with hyphenation hints. In the german

> a hyphen between them, e.g. "Select-Klausel" or "depends-Abh\"angigkeit", 
> to make the change of language clear (there are other reasons for
> explicit hyphens, too). Since TeX does not hyphenate such compounds,
> and they can get very long in german, we use a macro "" (with active
> doublequote), defined as \hskip\z@skip, so TeX will hyphenate again:
> Select-""Klausel, depends-""Abh"angigkeit ("a is short for \"{a}).
> tex4ht translates this to a space, which makes sense since browsers
> will not break the compounds without that space either. However, I'd
> prefer to not have such spaces. Could this be configurable?

Minted sometimes produces unexpected results. For example, << characters 
get translated to guilelemets. To prevent that, we define new configuration,
mintedfixes, where we can redefine macrod used by Minted to produce correct

The breaklines option for Minted environments and commands causes source code
lines to collapse into one line. We try to prevent that by basically disabling
this option.

As it can be declared in the preamble, we must patch the usepackage code.

It seems that TOC in Beamer doesn't work. It probably isn't that
important, as it is usually used only in frame outlines, which 
aren't used in \TeX4ht output anyway. I will remove the following

We must disable Beamer's framebreaking, as it can lead to tag mis-match.
It should still work in the picture mode, as we use the HLet command.

This should prevent insertion of SVG elements around columns:

 Beamer can break BibLaTeX's bibliography across several slides, 
 which can lead in tag mis-match, as the closing tags for the bibliography 
 are inserted as child of other element, than the opening tags.

 This redefinition uses Beamer's macros to insert tags for each individual
 bib item, without container item that would cause problems.

The calc package redefined \`'\setlength' to allow expressions of the
form `\Verb!width=.625\textwidth+5mm!'.  The macros \`'Gin@ewidth' and
\`'Gin@eheight' allow such values.  Hence, for such macros, we should
use  instructions like \`'\setlength\tmp:dim\Gin@ewidth'  instead of 
\`'\tmp:dim=\Gin@ewidth'.

Graphbox redefines \`'\Gin@setfile'  to make some manipulations with the

it isn't useful in XML anyway.

The first argument to SetHColor above is the XML code to be added for the
color, with the color itself referenced by \''\HColor'.  The second
argument is the same color name as provided to \''\color' of
color.sty.   That is, the configuration is employed in the following manner.

\Verbatim
   \Configure{SetHColor}
        {#1: XML code for color provided in \HColor}
        {#2: latex color name}
\EndVerbatim

The SetHColor typically is requsted indirectly in the following manner

\Verbatim
             \a:color{latex color name}
\EndVerbatim

Where \Verb=\a:color= is similar to.

\Verbatim
\Configure{color}
  {\Configure{SetHColor}
        {...XML code for color provided in \HColor...}%
  }
\EndVerbatim

The \Verb=\get:HColor= does the job of looking for XML color value,
and it assignes that value to \Verb=\HColor=.

The \Verb!\color{red}! instruction might be problematic since it does
not on its own determine the extent of the text to be colored.  As a
result, its effect can cross logical boundaries. That is against the
philosophy of markup languages in general and of XML in particular.

It is possible to implement the \Verb!\color{...}! feature but I'm not
sure it is desirable to do so.  I think it is preferable to expect
users to use commands of the form \Verb!\textcolor{red}{...}! for code
fragments.

\SubSection{Dimensions}

We put the picture into a box so that we will be able to measure its
dimensions. Now, we must be careful not to introduce strange stuff
into the box that will ruin the measurements.  In DraTeX we might be
less careful because
spaces are ignored due to their catcode of 9.

In DraTeX dimensions don't care about the color of the pixels, but
once we go to dvips and/or convert we loose the invisible character
around the visible picture.  This causes a statement for improper
dimensions, and so for a distortion of the picture when the dimensions
are stated in \`'IMG'.  To avoid this, we can put rulers 
\`'\hrule height 1pt  \vskip2pt  \vbox\bgroup'
and
\`'\egroup  \vskip2pt  \hrule height 1pt'
at the start and end of the vbox that span to the full width.
However, such rulers are not alway desirable.

Hence, we go for the following instead of
\`'\DrawIMG{ WIDTH="\DrawWidth" HEIGHT="\DrawHeight"}'.

\`'\affaddr{The Th{\large{\sf{\o}}}rv{$\ddot{\mbox{a}}$}ld Group}\\'
\item Empty picture in copyrightspace of acm-proc-article-sp
\item The definition \''\@ptsize{}' is improper---it should provide a number
\item
No defintion for \''\@xtitlenote'. Used in
\''\def\titlenote{\@ifnextchar[\@xtitlenote'
\item  \''\newfont' provides a tex font; not a latex font. Hence,
for instance, the braces in \''\confname{\the\conf}'  are useless (and
misleading for the human eyes). 
\item Missing \''\def\endthebibliography{\endlist}'
\item Use

\Verbatim
\def\thesubsubsection{\thesubsection.\arabic{subsubsection}}

We convert most of the musicography symbols to pictures.
It isn't optiomal, but I found that corresponding Unicode characters
are either missing, or produce weird overlapping with the following
character.

The biggest issue with pictures is that it can produce a huge number 
of images for repeated use of the each command. It could be 
better to use specific image for each symbol only once. And
also to better handle the vertical alignment to the baseline, 
similarly how the \''\PicMath' command does. But my tests
in this area failed so far, so I will leave it as it is now.

An entry takes the form \`'\--#1/#2/#3/'.  The first parameter \`'#1'
is the major entry, the second parameter \`'#2' is the secodary entry,
and the third parameter \`'#3' is a range entry (empty, the character
\`'<', or the character \`'>').

The current approach is a variant of the definition in section 17.8 of
Writing with TeX. It uses a direct approach in which the full entries
and subentries are recorded at each location, and so eliminating the
need for the \''<tag>'. It also eliminates the format entry, but one
can  always merge this entry into the range entry by employing an
appropriate encoding scheme.

>>>

The command \''\leavevmode' introduces a blank line before the
introduction of the vertical space. The command is needed because
\TeX{} removes the vertical spaces that appear at the top of the
HPages.

  The value of \''\rightskip' is
adjusted to allow for ragged margin on the right, and so to decrease
the probability of getting hyphenated words in the title.
Moreover,
the
paragraph that  the title makes  must be completed before leaving
the braced  group, because the values that
\''\baselineskip' and \''\righskip' hold at the end of the paragraph are
the ones that count. A task that is achieved here with
 \''\bigskip'.

\fi
>>>

The command  \''\magstep'$\,i\/$ increases the size of the characters by a
factor of $(1.2)^i$. On the other hand,
 the normal distance between base lines is 12pt.
 Hence, the motivation for increasing this distance to 29.85pt
\hbox{(${}=\hbox{12}\cdot\hbox{(1.2)}^5$pt)}.

\''\ChapterCounter' is 0 for \''\LikeChapter', positive for \''\Chapter',

The empty \''\mark' ensures that the ones from a sections will not
change the definition of \''\:rightheader' in first HPage of the
chapter (when \''\firtmark' is the choice) and that nothing will
propogate from previous HPages.

The \''\write', and \''\mark'(?), commands introduce whatsis so we want
them in horizontal mode to avoid extra spaces. Also, for correct HPage

The interparagraph space that \''\parskip' contributes is introduced
when a new paragraph (i.e., horizontal mode) is entered. Within a list
we don't want  the first item to introduce such vertical space
in addition to the one introduced by the
head of the list.
Hence, we before the first item, \''\parskip'  give 0 cotribution.
Also, we want the space around the list (together with parskip) to equal medskip.

\`'\par\:bigskip' instead of just \''\:bigskip' allows a \''\nobreak' before the end of the lis.

\Section{Html Tables}

We need  the \''\HTable{...}' version for handling
TeX tables and for not modifying \`'&' with other
catcode or replacement command. Otherwise, \''\HTable...\EndHtable' 
are better because that don't ask for expandable stuff.

Defining the \''\HTable' in terms of \''\halign' is problematic
for a few reasons.

\List{1}
\item
Paragraph breaks are treated as space characters within \''\halign'.
Defining\''\par' to equal \''\the\ht:everypar' causes multiple calls to
\''\ht:everypar'.

\item Don't know how to get the \''</TABLE>' in place.

The \''\tablefootnote| command tries to print list of footnotes 
at the end of a table where they were used. I haven't found
a good way how to do this in TeX4ht, so we just use normal footnote
instead.

For non-pictorial accents \''\c', \''\b', and \''\d', we want just the
accented part.  The default definitions provide an alternative options.
In the last two cases, the  \''\accent' command uses faked access
number.

The last two faked fonts, similar to the definition of \''\t' in
plain.tex. There, however, we have \''\the\textfont1' instead of
\''\rm' and \''\rmfamily', which doesn't work in LaTeX for some
reasons (what are the reasons?).

\Section{Accents through `accents' Configurations}

When \''\hat{foo}' is encountered, a search is made for an \`'??-i'
that equals  \`'foo' in the given accent table. If found, do-found is
executed; otherwise, do-not-found is executed. The do-found can reference the
??-out through \`'#1'. The do-not-found can reference the 
old definition of \`'\hat' through \`'#1' and the foo through \`'#2'.

\NewConfigure{accents}[2]{\def\a:accents##1##2{#1}%

\List{*}
\item \`'\HChar{...}' sends forward a character to the next printable
char (can be refined to specific characters).  That is, it uses the
character of the command, with the decoration of the character that
follows.
\item \`'\special{t4ht@+...}' sends forward a string to the next printable
chr
\EndList

The space in the definition of \`'\check:sc' is to deal with caese
like \`'cmcsc10 at 14.4pt'.
