<h2 class="ChapterHead"><a
name="QQ1-3-5"></a>From LaTeX to HTML</h2>
<!--l. 1791--><p class="noindent"><a
name="features"></a>The translation of a LaTeX source file into HTML involves of loading <span
class="cmtt-10">tex4ht.sty </span>and *.4ht style files, choosing the
desirable options for the translation, compiling the source into <span
class="cmtt-10">dvi </span>code with the native LaTeX engine, and
postprocessing the outcome with the <span
class="cmtt-10">tex4ht </span>and <span
class="cmtt-10">t4ht </span>programs (see <a
href="mn38.html" >overview</a>).
</p><!--l. 1800--><p class="indent"> <a
name="index3-5001"></a>The <span
class="cmtt-10">htlatex </span>command loads a script which takes on itself to invoke the different steps of the process, without
user intervention. The command assumes the form
</p>
<div

class="cmtt-10">" "</span><span
class="cmti-10">options3</span><span
class="cmtt-10">"</span></div>
<!--l. 1809--><p class="noindent">where the first set of options is for the <span
class="cmtt-10">tex4ht.sty </span>and <span
class="cmtt-10">*.4ht </span>style files, the second set is for the <span
class="cmtt-10">tex4ht</span>
postprocessor, and the third for the <span
class="cmtt-10">t4ht </span>postprocessor. For instance,
</p><!--l. 1822--><p class="indent">
</p><dl > <dt><span
class="cmtt-10">htlatex filename</span></dt><dd>
This command requests a translation according to the default conditions, which are set to produce HTML
transitional 4.0 code.
</dd><dt><span
class="cmtt-10">htlatex filename "html,2,info"</span></dt><dd>
This command is equivalent to the previous one, specifying explicitly the option <span
class="cmtt-10">html </span>for <span
class="cmtt-10">tex4ht.sty </span>instead of
doing so implicitly.
<!--l. 1831--><p class="indent"> In addition, the command requests a break up of the output into separate web pages, in accordance to the two
top sectioning levels of the document.
</p><!--l. 1835--><p class="indent"> Moreover, it asks for a listing in the log file of the information available for the style files in use. That
information, among other things, also introduces additional values available for the first list of options. </p></dd><dt><span
class="cmtt-10">htlatex</span>
<span
class="cmtt-10">filename "" "dbcs/!"</span></dt><dd>
This command requests the loading of the dbcs branch of Chinese hypertext fonts (on top of those already requested
by the default setting). </dd><dt> <a
name="index3-5002"></a> <a
name="index3-5003"></a> <a
name="index3-5004"></a> <a
name="index3-5005"></a> <a
name="index3-5006"></a><span
class="cmtt-10">htlatex filename "foo,frames" "" "-p"</span></dt><dd>
This command requests LaTeX to load a private configuration file, named <span
class="cmtt-10">foo.cfg</span>, and to place the content and
table of contents in separate frames. In addition, it asks <span
class="cmtt-10">t4ht </span>not to produce bitmaps for pictures.
</dd></dl>
<h2 class="ChapterHead"><a
name="QQ1-3-6"></a>Available Values for the Options</h2>
<!--l. 1864--><p class="noindent"><a
name="index3-6001"></a>The fields of <span
class="cmti-10">option1 </span>should be separated by commas. An ‘<span
class="cmtt-10">info</span>’ field requests a listing in the .log file of many of the
the available values. If the list is not empty, it must start with the entry ‘<span
class="cmtt-10">html</span>’, ‘<span
class="cmtt-10">xhtml</span>’, or a name of a private
configuration file.
</p><!--l. 1871--><p class="indent"> The fields of <span
class="cmti-10">option2 </span>and <span
class="cmti-10">options3 </span>should be separated by spaces. The available values can be listed by
executing the postprocessors <span
class="cmtt-10">tex4ht.c </span>and <span
class="cmtt-10">t4ht.c</span>, respectively, without arguments (or with wrong sets of
arguments).
</p><!--l. 1876--><p class="indent"> The first field of <span
class="cmti-10">option2 </span>should be empty or a subdirectory of <span
class="cmtt-10">ht-fonts </span>(typically augmented with an
exclamation mark ‘<span
class="cmtt-10">!</span>’). A space should separate the first field from the second one, also when the first field is
empty.
</p><!--l. 1881--><p class="indent"> The underlying output formats of available <span
class="cmtt-10">htlatex</span>-like commands are tailored into the commands through
fields of <span
class="cmti-10">option1</span>. The names of these fields are defined in <span
class="cmtt-10">tex4ht.4ht </span>and <span
class="cmtt-10">tex4ht.usr </span>(see <a
href="mn6.html#confFiles">General Configuration
Files</a>). These values should be of little interest to most users.
</p><!--l. 1889--><p class="indent"> <a
name="index3-6002"></a> <a
name="index3-6003"></a>Different variants of the <span
class="cmtt-10">htlatex </span>command may be invoked by introducing the commands as
arguments to a driver named <span
class="cmtt-10">mk4ht</span>. When provided without arguments, the driver lists the commands it
recognizes.

name="index3-7002"></a> <a
name="index3-7003"></a>The ‘<span
class="cmtt-10">xhlatex</span>’ command is a variant of the ‘<span
class="cmtt-10">htlatex</span>’ command requesting XHTML
output. It consists just of a call to ‘<span
class="cmtt-10">htlatex</span>’ with the entry ‘<span
class="cmtt-10">xhtml</span>’ in the first list of options. For instance,
‘<span
class="cmtt-10">xhlatex filename</span>’ or ‘<span
class="cmtt-10">htlatex filename "xhtml"</span>’.
<!--l. 1916--><p class="noindent">To request a Unicode representation of symbols, the first list of options should include the ‘<span
class="cmtt-10">uni-html4</span>’ entry, and
the second list should include the ‘<span
class="cmtt-10">-cunihtf</span>’ entry preceded by space. For instance, ‘<span

<span

configurations for translating LaTeX math into MathML, and extra configurations for adjusting the outcome to
Mozilla, MathPlayer, and PMathML CSS. Only presentational MathML is supported.

<!--l. 2435--><p class="noindent"><a
name="index3-18001"></a>The outcome of the translations should be checked by validators for proper syntax. Typically, with the presence of
validators, errors are easy to detect and correct, but they require human intervention.
</p><!--l. 2440--><p class="indent"> TeX4ht doesn’t offer a built-in parser to verify the correctness of the outcome. However, external validator(s)
can quite easily be integrated into the compilation process.

<h2 class="ChapterHead"><a
name="QQ1-3-19"></a>Recommendations</h2>
<!--l. 2449--><p class="noindent">To keep with the spirit of LaTeX and hypertext, in which style is assumed to be separated from content, the users
are encouraged to avoid inserting TeX4ht code into their source files. Instead, they should place their
modifications, to the default settings, within private configuration files to be loaded by htlatex-like
commands.
</p><!--l. 2456--><p class="indent"> On the other hand, it should be noted that hypertext markings should adhere to strict rules specified by
different standards. Consequently, it is strongly advised to check the output obtained from the default
configurations, before trying to tailor new ones.
